+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or

+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read

+
+	maint: update bootstrap, (re-)enable po file generation
+	In commit 4694c4e67, I disabled bootstrap pulling in po files, because
+	I got an error while attempting to get them, and remembered that while
+	the experimental 2.0 has a .pot file, branch-1.4 (and the 1.4.18
+	release) historically did not.  Basically, since the translation
+	project does not have any m4.pot corresponding to a released m4 that
+	needs it, they deleted tp/latest/m4, and with nothing to pull from,
+	rsync fails.  I did not, however, realize that commit 610290de had
+	intentionally added translation support, such that m4 1.4.19 WILL have
+	translations; so until I get that directory reinstated by releasing
+	1.4.18b, I'll just use './bootstrap --skip-po'.
+
+	Meanwhile, Gary's upstream bootstrap has had some commits
+	(https://github.com/gnulib-modules/bootstrap.git)
+	Regenerate them via:
+	for f in gl/build-aux/*; do cp ~/bootstrap/build-aux/$(basename $f) $f; done
+	gl/build-aux/inline-source gl/build-aux/bootstrap.in > bootstrap
+
+	* gl/build-aux/*: Sync from upstream.
+	* bootstrap: Regenerate.
+	* bootstrap.conf (m4_bootstrap_options_prep): Re-enable po.
+	* NEWS: Document this as intentional.
+	Fixes: 4694c4e67

+2021-05-07  Eric Blake  <eblake@redhat.com>
+
+	maint: fix syntax-check issues
+	* src/Makefile.am (m4_LDADD): Rename...
+	(LDADD): ...to this, and use spelling that satisfies syntax-check.
+	* po/POTFILES.in: Update to satisfy syntax-check.
+	* cfg.mk (old_NEWS_hash): Update with 'make update-NEWS-hash'.
+
+	maint: bump copyright year
+	* all: Use 'make update-copyright' to add 2021.
+
+	README: add GNU Project notice
+	* README: Add section to attract more people towards the GNU project.
+	Inspired by a suggestion from Jose E. Marchesi <jemarch@gnu.org> on
+	the gnu-prog-discuss mailing list.
+
+2021-04-22  Eric Blake  <eblake@redhat.com>
+

+
+	maint: another gnulib update
+	* gnulib: Update to latest, to fix build on rawhide.
+
+2021-04-21  Eric Blake  <eblake@redhat.com>
+
+	symtab: use less memory in pushdef stacks
+	No need to xstrdup identical names when we can share the same name
+	across the pushdef stack.
+
+	* src/symtab.c (free_symbol): Don't free shared name.
+	(lookup_symbol): Share name across pushdef stack.
+
+2021-04-21  Eric Blake  <eblake@redhat.com>
+
+	symtab: make symtab private
+	No need for a leaky abstraction of freezing to have to duplicate how
+	our symbol hash table is organized; use the public function
+	hack_all_symbols instead.  This will make it easier to refactor the
+	symbol table (such as automatic resizing, or switching to a trie).
+
+	* src/m4.h (symtab, SYMBOL_NEXT): Make private.
+	* src/freeze.c (produce_frozen_state): Split out...
+	(freeze_symbol): ...new helper, for use by hack_all_symbols.
+	* src/symtab.c (lookup_symbol, symtab_print_list): Update to treat
+	next as internal-only code.
+
+2021-04-21  Eric Blake  <eblake@redhat.com>
+
+	symtab: sort by hash before name
+	It is faster to do an integer compare than a string compare when
+	managing hash table collisions (reserving a string compare for ties).
+	Testing with CFLAGS=-DDEBUG_SYM=1 and 'time M4=src/m4 autoconf -f',
+	the results are noticeable; on my machine, execution speeds up from
+	2.3s to 2.2s, and the debug trace that used to report:
+
+	m4: lookup mode 0 called 1243301 times, 7859589 compares, 6734330 misses, 23941043 bytes
+
+	now reports
+
+	m4: lookup mode 0 called 1243301 times, 1125259 compares, 0 misses, 12433237 bytes
+
+	* src/m4.h (struct symbol): Add hash member.
+	* src/symtab.c (lookup_symbol): Sort by hash first, then name.
+	(symtab_print_list): Add hash debug.
+
+2021-04-21  Eric Blake  <eblake@redhat.com>
+
+	maint: switch from git:// to https:// for gnulib submodule
+	https:// is nicer than git:// for a transport for avoiding
+	man-in-the-middle attacks, provided that the server is using a
+	new-enough version of git to make https:// efficient (which
+	savannah does).
+	* .gitmodules: Prefer better URL.
+
+2021-04-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	maint: port to Solaris 10
+	Add libraries needed by current Gnulib.
+	* src/Makefile.am (m4_LDADD): Add LIB_CLOCK_GETTIME,
+	LIB_GETRANDOM, LIB_HARD_LOCALE, LIB_POSIX_SPAWN,
+	LIB_SETLOCALE_NULL, LIBUNISTRING, INTL_MACOSX_LIBS.
+	These are all needed by current Gnulib, according to gnulib-tool.
+	LIB_CLOCK_GETTIME is certainly needed for Solaris 10; otherwise
+	the m4 link fails with clock_gettime not found.
+
+	maint: port to macOS 11.2.3 (arm64)
+	* m4/gnulib-cache.m4: Add fopen-gnu, replacing cloexec and fopen.
+	Avoid getopt-posix-tests, since they are not needed for m4
+	and currently fail on macOS 11.2.3 (arm64).
+	* src/builtin.c (m4_incr, m4_decr): Avoid undefined behavior
+	on integer overflow that causes tests to fail on macOS.
+	* src/debug.c (debug_set_output):
+	* src/output.c (m4_tmpfile, m4_tmpopen):
+	* src/path.c (m4_fopen):
+	Use GNU fopen with "e" rather than set_cloexec_flag.  This is
+	simpler, and works around a Gnulib bug on macOS with fopen
+	being replaced by rpl_fopen sometimes but not other times.
+	* src/freeze.c (produce_frozen_state): Use GNU fopen with "e";
+	no need to expose the fd to subprocesses.
+
+	build: update gnulib submodule to latest
+
+2021-04-17  Eric Blake  <eblake@redhat.com>
+
+	symtab: drop redundant symbol flag
+	In writing the previous patch, I noticed that the shadow flag is only
+	ever set when a pushdef stack is present, which makes it redundant now
+	that the pushdef stack is separate from the hash collision stack.
+
+	* src/m4.h (SYMBOL_SHADOWED): Delete.
+	* src/builtin.c (dump_symbol): Simplify, now that hack_all_symbols
+	no longer visits shadowed macros.
+	* src/symtab.c (lookup_symbol, symtab_print_list): Simplify.
+
+2021-04-17  Eric Blake  <eblake@redhat.com>
+
+	symtab: better handling of macro stacks
+	I ran into a scenario where running a program took 22s with the
+	default -H509, but less than a second with -H517 1.  The culprit?  A
+	collision between 'stack' and 'substr' in the default hash table size
+	caused lookups for substr to get progressively slower as pushdef stack
+	got deeper.  This is easy enough to fix, and may also make it easier
+	to dynamically grow the hashtable.
+
+	1 https://lists.gnu.org/archive/html/bug-m4/2021-04/msg00000.html
+
+	* src/m4.h (struct symbol): Add stack member.
+	* src/symtab.c (lookup_symbol): Separate stack from bucket list.
+	(symtab_print_list): Update traversal to match.
+	* src/freeze.c (produce_frozen_state): Likewise.
+	(reverse_symbol_list): Reverse stack, not bucket.
+
+2021-04-17  Eric Blake  <eblake@redhat.com>
+
+	input: optimize macro tail-call memory usage
+	I encountered an m4 program that performed over 20 million iterations
+	of a tail-call recursion paradigm.  Without this patch, memory usage
+	grew to over 6 gigabytes, pausing the program for several seconds when
+	the recursion finally ended just to reclaim the memory.  But with the
+	patch, m4 never needed more than 3 megabytes of resident memory.
+
+	* src/input.c (push_string_init): Prune empty string blocks before
+	starting another one.
+
+2021-04-17  Eric Blake  <eblake@redhat.com>
+
+	maint: update gnulib and fix build failures
+	I got failures when trying to bootstrap:
+
+	bootstrap: getting translations into po/.reference for m4...
+	receiving incremental file list
+	rsync: change_dir "/latest/m4" (in tp) failed: No such file or directory (2)
+
+	since m4-1.4 has no translation files, and the translation project
+	dropped the stale .po files for the unreleased 1.9 development branch.
+
+	Once that was fixed, I also got compilation failures, from an
+	incomplete update to the gnulib execute module:
+
+	builtin.c: In function 'm4_syscmd':
+	builtin.c:968:44: error: passing argument 3 of 'execute' from incompatible pointer type -Werror=incompatible-pointer-types
+	  968 |   status = execute (ARG (0), SYSCMD_SHELL, prog_args, NULL, false,
+	      |                                            ^~~~~~~~~
+	      |                                            |

+
+	Port recent changes to AIX 7.1
+	* src/Makefile.am (m4_LDADD): Add LIB_MBRTOWC, LIB_SETLOCALE.

+
+2020-07-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Support gettext and proper names
+	This way, ‘m4 --version’ outputs “Written by René Seindal”

+	As the Translation project adds translations, NLS should
+	get better.
+	* .gitignore: Add translation-related file names.
+	* AUTHORS, ChangeLog-2014, NEWS, README, acinclude.m4, c-boxes.el:
+	Spell “François” and “René” without ASCIIfying.
+	* HACKING: Add Gettext as a prereq.
+	* Makefile.am (SUBDIRS): Add po.
+	* configure.ac: Do not use -Wvla.  Add AM_GNU_GETTEXT

+
+	maint: generate ChangeLog from git commits
+	Follow the practice set in numerous other GNU projects, where
+	the ChangeLog (since 2015) is generated from git commit messages.
+	This avoids duplication or subtle differences between the two,
+	as well as making it easier to merge patches across branches
+	(as good as Bruno Haible's 'git-merge-changelog' helper program
+	is, it still doesn't handle cross-branch cherry-picks very well).

+
+	maint: make silent builds the default
+	The user still has full control over verbosity levels, both setting
+	their per-project defaults at configure time (or even in a config.site
+	file), as well as a per-run override. But these days, most projects
+	are defaulting to silent rules without user intervention.
+
+	* configure.ac (AM_SILENT_RULES): Add, to match what most projects

+2016-12-31  Eric Blake  <eblake@redhat.com>
+
+	maint: release no longer creates a diff file
+	Ever since commit f1cf390 (1.4.14 release), we no longer create
+	diff files as part of the release process.  These days, it is
+	assumed that it is easier to download a fresh tarball rather
+	than to try and use a diff file to patch an older tarball.
+
+2016-12-30  Eric Blake  <eblake@redhat.com>
+
+	doc: drop obsolete @setcontentsaftertitlepage
+	texinfo 6.1 complains (during 'make dvi'):
+
+	/home/eblake/m4-1.4/doc/./m4.texi:9: @setcontentsaftertitlepage has been remove
+	d as a Texinfo command; move your @contents command if you want the contents af
+	ter the title page..
+
+	It turns out that eliminating the command has no effect - modern
+	tools correctly emit the contents in-place, right after the title
+	page, so it was leftover cruft from an older time.
+
+	* doc/m4.texi: Satisfy newer texinfo.

+	* doc/gendocs.sh: Don't save an old version in m4 CVS!
+	* doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case

+2005-02-03  Gary V. Vaughan  <gary@gnu.org>
+
+	Modernise the configury a little to prevent spurious errors from

+	* config-h.in: ...this to better support DOS 8.3 file systems.

+	* src/output.c (mkstemp): Make non-static, and build regardless of

+	Remove the sed filter after ansi2knr for debug.c.  Use $O instead
+	of $U, put underline in extensions rather than in basenames.  Use

+	Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
+	of ansi2knr whenever it is needed.
+	* configure.in: Adjusted for correct STACKOVF substitution.

+	Reported by Kaveh R. Ghazi.

+
+	* stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in

+
+	* builtin.c (numeric_arg): Use strtol and verify the conversion,

+	adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
+	handlers), and a default error message if the fault address is not
+	available (when neither siginfo.h nor BSD sigcontext are supported).
+	* configure.in: Changes for stackovf.h: Check for sigcontext,
+	sigaction, sigstack, and define rlim_t as int if necessary.
+	* acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
+	* examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.

+Sat Jul  2 00:58:47 1994  François Pinard  (pinard@icule)
+
+	* configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
+	because siginfo.h is unrelated to standard headers, and siginfo.h
+	is already checked for.
+	Reported by Joseph E. Sacco.
+
+	* acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
+	PROTOTYPES.
+	* aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
+	AC_PROTOTYPES.
+
+Wed Jun 29 22:41:53 1994  François Pinard  (pinard@icule)
+
+	* builtin.c (substitute): Use \& to represent this part of the
+	string which was matched by the whole regexp, instead of
+	representing the whole string.  Any usage of \0 issues a warning
+	and acts like \&, it will disappear in some subsequent release.
+
+Mon Jun 27 14:24:23 1994  François Pinard  (pinard@icule)
+
+	* m4.c: Complete prototype for forwarded declaration of usage.
+
+	* input.c (init_macro_token): Correct own reference in error
+	message.  Previous name get_macro_func was referred to instead.

+	prototype to forwarded declarations.  Declare parameter v1 as
+	eval_t * instead of int *.  Same for local variable v2 in dyadic
+	functions.  Same for result in exp_term.
+	* builtin.c (m4_eval): Declare value as eval_t instead of int.
+	(ntoa): Declare value as eval_t instead of int.  Declare uvalue as

+
+	* macro.c: Complete the prototypes of forwarded expand_macro and
+	expand_token.
+	Reported by Thorsten Ohl.
+
+	* m4.h: Define voidstar as void * or char * depending on __STDC__.

+	stamp-h does not exist yet.  This avoids running it a second time
+	just after the initial ./configure.
+	Reported by David MacKenzie and Tom McConnell.
+
+	* m4.h: Replace the enum debug_info declaration with a series of
+	#define's.  The Ultrix 3.1 compiler would otherwise need casting
+	(int) to most references, when used in expressions.
+	Reported by Tom McConnell.
+
+Sat Jun 25 00:10:05 1994  François Pinard  (pinard@icule)
+
+	* aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
+	following an idea from Brook G. Milligan.  AC_HAVE_PROTOTYPES
+	calls the compiler.  Previously, FP_PROTOTYPES was only calling
+	the preprocessor; by not being subject to CFLAGS, this was
+	discouraging those flags asking for ANSI compilation.
+	* acconfig.h: Document HAVE_PROTOTYPES.
+	* configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
+	* m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
+	Reported by Eric Backus.
+
+	* configure.in: Substitute CFLAGS and LDFLAGS, taking their value
+	from the environment.  Default CFLAGS to -g if not set.
+	* Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
+	* lib/Makefile.in: Have CFLAGS substituted from configure.
+	Reported by Eric Backus and Tom McConnell.
+
+	* configure.in: m4_undefine changeword before using AC_ENABLE.
+
+	* m4.h: Declare prototypes for error (for ANSI compilers only),
+	prefix_all_builtins and reference_error.
+	Reported by Tom McConnell.
+
+	* input.c (set_word_regexp): Do not try to initialize the array
+	test from a string, this does not work with non-ANSI compilers.
+	Reported by Eric Backus.
+
+	* Makefile.in (dist): Clean examples/ before saving it.
+	(distclean-local): Also remove stamp-h.
+	Reported by Eric Backus.
+
+	* Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
+	non ANSI compilers.
+	Reported by Tom McConnell.
+
+	* checks/Makefile.in (clean): Depends on mostlyclean.
+	(mostlyclean): New goal.

+	Declare TOKEN_DATA_FUNC macro.
+	* builtin.c: Declare changeword.

+	default_word_regexp is true.  Else, match using a new code.  Save
+	the original text.
+	* macro.c (expand_token): Ship out original text if not a macro
+	name.
+	Reported by Krste Asanovic and Pete Chown.
+
+	These modifs all depend upon ENABLE_CHANGEWORD
+	* m4.h: Declare external user_word_regexp.
+	* m4.c: Declare user_word_regexp, and initialize it from
+	--word-regexp or -W, or NULL if not specified.
+	* input.c: Use user_word_regexp if specified, instead of
+	DEFAULT_WORD_REGEXP.
+
+	* Makefile.in (m4): Revert Jan 3 1994 change.  I'm unable to
+	agree with it.
+
+	* Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
+	* checks/Makefile.in: Empty the suffix list.
+	Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
+
+	* m4.c: Declare nesting_limit and initialize it to 250.
+	Implement -LNUMBER or --nesting-limit=NUMBER to change its
+	value.
+	* m4.h: Declare nesting_limit as external.
+	* macro.c (expand_macro): Stop execution whenever nesting limit
+	is exceeded.
+	Reported by Bengt Mertensson.
+
+	* eval.c (evaluate): Diagnose excess characters in eval input.
+	Things like `eval(08)' used to return 0 with no diagnostic.
+
+	* m4.h: Capitalize first letter of all macro arguments in
+	definitions.
+
+	* m4.c: Declare warning_status, initialize it to 0.  Add new
+	option -E, or --fatal-warnings, which sets warning_status to
+	EXIT_FAILURE instead.
+	* m4.h: Declare external warning_status.  Define EXIT_SUCCESS and
+	EXIT_FAILURE if not otherwise done by header files.
+	* m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
+	* m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
+	eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
+	argument of all M4ERROR calls.
+	Reported by Noah Friedman.
+
+	* examples/incl-test.m4: Renamed from incl_test.m4.
+	* examples/include.m4: Include incl-test.m4 instead of
+	incl_test.m4.
+	* examples/multiquotes.m4: Renamed from multi-quotes.m.
+
+Wed Jun 22 21:58:54 1994  François Pinard  (pinard@icule)
+
+	* configure.in: Avoid USE_STACKOVF if <siginfo.h> not found.  Note
+	that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
+	also tested it on a Sun Sparc workstation running SunOS 4.x.
+
+	* format.c (format): When not HAVE_EFGCVT, m4 was failing the
+	49.format check, abusing a `union values' argument with sprintf
+	without selecting the proper field.  Now, save the formatting type
+	first, delaying the fetch of the corresponding argument.
+	Reported by Joseph E. Sacco and Tom Quinn.
+
+	* format.c (format): Remove const from char *fmt declaration when
+	not HAVE_EFGCVT, because a NUL may be forced into it.
+
+	* m4.h: Declare atof() when not STDC_HEADERS.
+	Reported by Joseph E. Sacco.
+
+	* Regenerate configure using Autoconf 1.11, this corrects a
+	problem about an incorrect cpp seting on NeXT 3.1.
+	Reported by Alexander Lehmann.
+
+Sun Jun  5 16:25:19 1994  François Pinard  (pinard@icule)

+
+Wed May  4 23:59:39 1994  François Pinard  (pinard@icule)

+
+	* m4.h: Rename Args() to _().

+	warning from gcc about `repl' possibly used before defined.
+	Reported by Jim Meyering.
+
+	* m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
+	Reported by Jim Meyering.
+
+Tue Jan 25 18:39:37 1994  François Pinard  (pinard at icule)
+
+	* m4.h: Move the conditional definition of volatile after the
+	inclusion of system files, because they may define it first.
+
+Tue Jan  4 19:46:50 1994  François Pinard  (pinard@icule)
+
+	* checks/Makefile.in (CHECKS): Add a useless `*' before `', to

+	Reported by Vern Paxson.
+
+Mon Jan  3 00:21:45 1994  François Pinard  (pinard@icule)

+
+	* m4.h: Delete extern sys_nerr, sys_errlist declarations, and
+	syserr() macro.  Delete errref, add reference_error and M4ERROR.
+	* m4.c: Replace errref, which was returning an input reference

+	* builtin.c, output.c: Use errno as second parameter to error,
+	instead of using syserr() with %s.
+	* *.c: Use M4ERROR instead of error: no more errref() with %s.
+	Doing so, the program name appears after the input reference

+
+Wed Nov 24 22:16:15 1993  François Pinard  (pinard@icule)

+
+	* builtin.c (m4_eval): Cast strlen to (int) before comparing.
+
+	* input.c (input_init): Initialize quote and comment strings

+	expected is on the left and the obtained on the right.
+

+Sat Dec 19 08:21:34 1992  François Pinard  (pinard at icule)
+
+	* Release 1.0.3
+	This is still a	beta release for the future GNU m4 version 1.1.
+
+	* lib/alloca.c: New, from elsewhere.
+	* lib/Makefile.in: Distribute it.  Define and use $(ALLOCA).
+
+	* m4.h: Do not define index/rindex if already defined.  If
+	FALSE/TRUE are already defined, do not redefine them, but merely
+	define boolean typedef to int.
+
+	* Makefile.in: Use $(DEFS) while compiling ansi2knr.
+	* ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
+	because some C compilers do not like connectives with #ifdef.
+	* m4.h: Define `volatile' only if __GNUC__, instead of once for
+	__GNUC__ and once for __STDC__.
+	* lib/regex.h: Leave const alone, AC_CONST will take care of it.
+
+	* checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
+	Makefile dependencies.  Without it, make keeps destroying and
+	remaking $(CHECKS) in a loop (why?).  Distribute .all_stamp.
+
+	* m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
+	to diversion/DIVERSION, this was a spelling error.

+	* m4.c: Declare version, remove #include "version.h".
+	* version.h: Deleted.
+	* Makefile.in: Remove references to version.h.
+
+	* output.c (shipout_text): Centralize all `#line NUM "FILE"'
+	production, by using a simpler and more robust algorithm.  This
+	solves the problem of synclines sometimes written in the middle of
+	an output line.  Delete sync_line() and output_lines variable.
+	* m4.h: Remove sync_line prototype and output_lines declaration.
+	* input.c (next_char), output.c (shipout_text): Remove references
+	to output_lines.
+	* input.c (push_file, pop_file): Merely put the value -1 in
+	output_current_line instead of calling sync_line, for delaying a
+	single `#line NUM FILE' before next output line.  Do not test
+	for sync_output, because this is unnecessary clutter.
+	* output.c (make_divertion, insert_divertion): Idem.
+	* input.c: Rename must_advance_line to start_of_input_line, for
+	consistency.
+
+	* debug.c (trace_header): Select a new debug line format, which
+	better complies with GNU standards for formatting error messages.
+	With option `-dfl', M-x next-error might be used on the output.
+	* m4.c (vmesg): Adjust format of error output to GNU standards.
+	* m4.texinfo: Adjust examples for `make check' to work.
+
+	* m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
+	case for enum debug_info constants, which were all lower case.
+
+	* builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
+	re_search_2.
+	* lib/regex.ch: Use new version from textutils 1.3.6, with some
+	collected patches.  I tried a few times using newer regex.ch, it
+	mysteriously stopped aborting with this one.  Insecure feeling...
+	* lib/Makefile.in: Distribute regex.ch.old, just in case!
+
+Fri Dec 18 11:08:03 1992  François Pinard  (pinard at icule)
+
+	* m4.c: Change `--no-warnings' to `--silent'.
+	Reported by David MacKenzie.
+
+	* m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
+	leave it off for now.  See comment in m4.c for justification.
+	Reported by David MacKenzie.
+
+	* configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
+	* m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
+
+	* Makefile.in: Add a new `info' goal.  Use macro MAKEINFO.
+
+	* Makefile.in: Ensure recursive cleaning is done before local
+	cleaning for all clean goals.
+
+	* builtin.c (ntoa): Ensure the value is always interpreted as a
+	signed quantity, whatever the radix is.
+
+Wed Nov 18 07:57:19 1992  Jim Meyering  (meyering@idefix)
+
+	* builtin.c, format.c, input.c: Split long lines.

+
+	* configure.in: Find some awk.
+	* Makefile.in: Add $(AWK) to MDEFINES.
+	* checks/Makefile.in: Transmit $(AWK) to get_them.
+	* checks/get_them: Use $AWK instead of gawk.  Add a close in the
+	awk script when switching files, because without this, mawk runs
+	out of file descriptors.
+
+Mon Nov 16 20:42:56 1992  François Pinard  (pinard at icule)
+
+	* Makefile.in (realclean): Delete m4.info*.

+	* Makefile.in: Adjust and link with checks/Makefile.
+	* checks/Makefile.in: New.
+	* configure.in: Output checks/Makefile.

+	recognizable by next-error, also use a better message.
+
+Mon Nov 16 07:48:52 1992  Jim Meyering  (meyering@idefix)
+
+	* m4.h __GNUC__: Use __volatile__ instead of `volatile.'
+	And use that only if __GNUC__ since we're using it's GCC-specific
+	semantics that tell the compiler the associated function doesn't
+	return.
+
+	* builtin.c (substitute): Don't use character as an array index.
+	(dumpdef_cmp): Make formal arguments `const void *' to avoid
+	warnings with gcc -W -Wall on systems with qsort prototype.
+	(m4_errprint): Cast obstack_finish to `char *' to avoid warnings
+	from gcc -W -Wall.
+
+	* eval.c (most functions): Add parentheses to assignments used
+	as truth values go avoid warnings from gcc -Wall.
+
+	* input.c, m4.c, output.c, path.c, symtab.c: Declare static
+	any functions that don't need external scope.
+
+	* builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
+	(many functions and arrays): Declare `const'.
+
+Sun Nov 15 09:42:09 1992  François Pinard  (pinard at icule)
+
+	* *.ch: Rename nil to NULL, using the declaration from <stdio.h>,
+	removing the declaration from m4.h.  Also rename false to FALSE
+	and true to TRUE.
+
+	* lib/Makefile.in (Makefile): New goal.
+
+	* Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
+	so heavily loaded.  It gets more easily overridable, calling make.
+	Reported by Jim Meyering.
+
+	* Makefile.in (dist): Get .fname from the current directory name,
+	instead of from version.h.  I need updating many files manually,
+	when the version changes, version.h is just one of them.
+
+Sat Nov 14 11:01:20 1992  François Pinard  (pinard at icule)
+
+	* m4.h: Remove the tag `boolean' on the enum introducing typedef
+	`boolean'.  This tag conflicts with <sys/types.h> on SVR4.
+	Reported by Tom McConnell.
+
+Fri Nov 13 00:12:50 1992  François Pinard  (pinard at icule)
+
+	* m4.texinfo: Correct the examples for 33.divert, 38.divnum,
+	39.cleardiv, which were describing missing or spurious newlines.
+	Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
+	do not depend on machine word size, `/bin/false' implementation,
+	or `wc' output format.  `make check' is more dependable, now.
+
+	* checks/check_them: Summarize the failed tests by listing their
+	name, at end.  If none, issue `All checks successful'.  Output
+	`Checking' instead of `Input file:'.
+
+	* checks/get_them, checks/check_them: Reindented.
+
+	* Makefile.in (dist): chmod a+r before making the tar file.
+
+Thu Nov 12 14:42:57 1992  François Pinard  (pinard at icule)
+
+	* builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
+
+	* input.c (next_token): Reinitialize token_buttom just after using
+	it as a watermark with obstack_free.  Or else, a future token, big
+	enough for triggering reallocation of the obstack chunk, could
+	void the initialized value of token_buttom, later causing panic in
+	obstack_free.  Rename token_buttom to token_bottom everywhere.
+
+	* m4.h: Before declaring errno, first include <errno.h> and
+	ensure that it does not define errno.
+	Reported by Richard Stallman.
+
+Wed Nov 11 17:40:35 1992  François Pinard  (pinard at icule)
+
+	* builtin.c: Define and use DECLARE macro for builtins.
+
+	* builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
+	argument, this is a common idiom for introducing long comments.
+
+	* builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
+	arguments.  The last argument was silently ignored.
+
+	* m4.c (cmd_error): Add a missing semicolon before va_end().
+
+Tue Nov 10 08:57:05 1992  François Pinard  (pinard at icule)
+
+	* Makefile.in: Now handle protoized sources.  Define and use U.
+	Compile and use ansi2knr with old compilers.  Update DISTFILES.
+	Add `aclocal.m4' to `configure' dependencies.
+	* ansi2knr.c: New, from Ghostscript distribution.
+	* configure.in: Define U through FP_PROTOTYPES for old compilers.
+	Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
+	* aclocal.m4: New, provide FP_PROTOTYPES.
+	* m4.h: Conditionnaly protoized through Args, save for varags.
+	* builtin.c: Protoized.  Then:
+	Include <sys/types.h> if size_t is not defined, before "regex.h".
+	(m4_ifelse): Fetch built-in name properly for diagnostic.
+	(m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
+	(m4_regexp): Add const to `msg' declaration.

+	(xfree): Accept void * instead of char *.
+	(xmalloc): Return void * instead of char *.
+	(xrealloc): Accept and return void * instead of char *.
+	* macro.c: Protoized.
+	* output.c: Protoized.
+	* path.c: Protoized.  Then cast some (char *) over xmalloc's.
+	* symtab.c: Protoized.
+
+Fri Nov  6 02:05:21 1992  François Pinard  (pinard at icule)
+
+	* m4.texinfo: Remove directory from diagnostics in 30.include,
+	51.eval, 56.errprint and 57.m4exit tests.
+
+	* m4.h: Remove declarations for int or void system functions, they
+	cause more conflicting trouble than they make good.
+

+Installation Instructions

+without warranty of any kind.
+
+Basic Installation
+==================
+
+   Briefly, the shell command './configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the 'README' file for
+instructions specific to this package.  Some packages provide this
+'INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package.
+It may also create one or more '.h' files containing system-dependent
+definitions.  Finally, it creates a shell script 'config.status' that
+you can run in the future to recreate the current configuration, and a
+file 'config.log' containing compiler output (useful mainly for
+debugging 'configure').
+
+   It can also use an optional file (typically called 'config.cache' and
+enabled with '--cache-file=config.cache' or simply '-C') that saves the
+results of its tests to speed up reconfiguring.  Caching is disabled by
+default to prevent problems with accidental use of stale cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how 'configure' could check whether to do them, and mail
+diffs or instructions to the address given in the 'README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point 'config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file 'configure.ac' (or 'configure.in') is used to create
+'configure' by a program called 'autoconf'.  You need 'configure.ac' if
+you want to change it or regenerate 'configure' using a newer version of
+'autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. 'cd' to the directory containing the package's source code and type
+     './configure' to configure the package for your system.
+
+     Running 'configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type 'make' to compile the package.
+
+  3. Optionally, type 'make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type 'make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the 'make install' phase executed with root
+     privileges.
+
+  5. Optionally, type 'make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior 'make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing 'make clean'.  To also remove the
+     files that 'configure' created (so you can compile the package for
+     a different kind of computer), type 'make distclean'.  There is
+     also a 'make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type 'make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide 'make
+     distcheck', which can by used by developers to test that all other
+     targets like 'make install' and 'make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the 'configure' script does not know about.  Run './configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give 'configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here is
+an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU 'make'.  'cd' to the
+directory where you want the object files and executables to go and run
+the 'configure' script.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.  This is known
+as a "VPATH" build.
+
+   With a non-GNU 'make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use 'make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple '-arch' options to the
+compiler but only a single '-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the 'lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, 'make install' installs the package's commands under
+'/usr/local/bin', include files under '/usr/local/include', etc.  You
+can specify an installation prefix other than '/usr/local' by giving
+'configure' the option '--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like '--bindir=DIR' to specify different values for particular
+kinds of files.  Run 'configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the default
+for these options is expressed in terms of '${prefix}', so that
+specifying just '--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to 'configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+'make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, 'make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+'${prefix}'.  Any directories that were specified during 'configure',
+but not in terms of '${prefix}', must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the 'DESTDIR' variable.  For
+example, 'make install DESTDIR=/alternate/directory' will prepend
+'/alternate/directory' before all installation names.  The approach of
+'DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of '${prefix}'
+at 'configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving 'configure' the
+option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
+
+   Some packages pay attention to '--enable-FEATURE' options to
+'configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to '--with-PACKAGE' options, where PACKAGE
+is something like 'gnu-as' or 'x' (for the X Window System).  The
+'README' should mention any '--enable-' and '--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, 'configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the 'configure' options '--x-includes=DIR' and
+'--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of 'make' will be.  For these packages, running './configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with 'make V=1'; while running './configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with 'make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
+is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX 'make' updates targets which have the same timestamps as their
+prerequisites, which makes it generally unusable when shipped generated
+files such as 'configure' are involved.  Use GNU 'make' instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
+workaround.  If GNU CC is not installed, it is therefore recommended to
+try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
+in your 'PATH', put it _after_ '/usr/bin'.
+
+   On Haiku, software installed for all users goes in '/boot/common',
+not '/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features 'configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, 'configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+'--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as 'sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file 'config.sub' for the possible values of each field.  If
+'config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option '--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with '--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for 'configure' scripts to share,
+you can create a site shell script called 'config.site' that gives
+default values for variables like 'CC', 'cache_file', and 'prefix'.
+'configure' looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all 'configure' scripts look for a site script.
+
+Defining Variables
+==================

+   Variables not defined in a site shell script can be set in the
+environment passed to 'configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the 'configure' command line, using 'VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified 'gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+'configure' Invocation
+======================
+
+   'configure' recognizes the following options to control how it
+operates.
+
+'--help'
+'-h'
+     Print a summary of all of the options to 'configure', and exit.
+
+'--help=short'
+'--help=recursive'
+     Print a summary of the options unique to this package's
+     'configure', and exit.  The 'short' variant lists options used only
+     in the top level, while the 'recursive' variant lists options also
+     present in any nested packages.
+
+'--version'
+'-V'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+'--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
+     disable caching.
+
+'--config-cache'
+'-C'
+     Alias for '--cache-file=config.cache'.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to '/dev/null' (any error
+     messages will still be shown).
+
+'--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names:: for
+     more details, including other options available for fine-tuning the
+     installation locations.
+
+'--no-create'
+'-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+'configure' also accepts some other, not widely useful, options.  Run
+'configure --help' for more details.

+GNU M4 NEWS - User visible changes.
+
+* Noteworthy changes in release 1.4.19 (2021-05-28) stable
+
+** A number of portability improvements inherited from gnulib, including
+   the ability to perform stack overflow detection on more platforms
+   without linking to GNU libsigsegv.
+
+* Noteworthy changes in release 1.4.18d (2021-05-11) beta
+
+** A number of portability improvements inherited from gnulib.
+
+
+* Noteworthy changes in release 1.4.18b (2021-05-07) beta
+
+** The symbol hash table now defaults to 65537 buckets instead of 509, as
+   modern systems have enough memory to benefit from fewer hash collisions
+   by default.
+
+** Introduce the use of gettext, with the immediate benefit of nicer
+   UTF-8 author names.  Over time, more translations of program messages
+   will become available.
+
+** A number of portability improvements inherited from gnulib.
+
+
+* Noteworthy changes in release 1.4.18 (2016-12-31) stable
+
+** Diagnose --word-regexp as unsupported if it was not configured.
+
+** Preliminary support for OS/2.
+
+** A number of portability improvements inherited from gnulib.
+
+
+* Noteworthy changes in release 1.4.17 (2013-09-22) stable
+
+** Fix compilation with newer glibc headers.
+
+** Fix a failure with diverting large amounts of text on mingw (does
+   not affect platforms that can rename an open file).
+
+** A number of portability improvements inherited from gnulib.
+
+
+* Noteworthy changes in release 1.4.16 (2011-03-01) stable
+
+** Fix regressions in the `index' builtin.  On glibc platforms, this
+   avoids false positives from a strstr bug in glibc 2.9 through 2.12;
+   on many other platforms, it fixes two separate regressions, a false
+   positive introduced in 1.4.11 and a false negative in 1.4.15.
+
+** A number of portability improvements inherited from gnulib.
+
+
+* Noteworthy changes in release 1.4.15 (2010-08-31) stable
+
+** Fix regression introduced in 1.4.9b where the `format' builtin could
+   crash on an invalid format string.
+
+** Fix compilation against newer glibc, and on AIX 7.1BETA.
+
+** A number of portability improvements inherited from gnulib.
+
+
+* Noteworthy changes in Version 1.4.14 (2010-02-24) stable
+  Released by Eric Blake, based on git version 1.4.13.*
+
+** Fix regression introduced in 1.4.12 where executing with stdout closed
+   could crash m4 on exit on some platforms.
+
+** Fix regressions introduced in 1.4.13 in the `esyscmd' builtin, where
+   closed file descriptors could interfere with child execution, and where
+   a child status of 127 made m4 print a spurious message to stderr.
+
+** Fix a security hole in 'make dist', present since at least M4 1.4, that
+   could affect anybody attempting to redistribute modified sources (see
+   Automake CVE-2009-4029).
+
+** A number of portability improvements inherited from gnulib.
+
+* Noteworthy changes in Version 1.4.13 (2009-04-01) stable
+  Released by Eric Blake, based on git version 1.4.12.*
+
+** The manual is now distributed under the terms of FDL 1.3.
+
+** The `divert' and `undivert' builtins have been made more efficient
+   when using temporary files for large diversions.
+
+** The `translit' builtin has been made more efficient when the second
+   argument is short.
+
+** The input engine has been optimized for faster processing.
+
+** The command line option `--debugfile', introduced in 1.4.7, now
+   treats its argument as optional, in order to allow setting the debug
+   output back to stderr when used without an argument; and order is now
+   significant with respect to command line files.  You must therefore use
+   `m4 --debugfile=trace file', not `m4 file --debugfile trace'.  This
+   change does not affect the deprecated `-o'/`--error-output' option.
+
+** The `syscmd' and `esyscmd' builtins can be configured to use an
+   alternate shell, via the new `configure' option `--with-syscmd-shell'.
+
+** A number of portability improvements inherited from gnulib.
+
+* Noteworthy changes in Version 1.4.12 (2008-10-10) stable
+  Released by Eric Blake, based on git version 1.4.11.*
+
+** Fix regression introduced in 1.4.4b where using `traceon' could delete
+   a macro.  This was most noticeable with `traceon(`traceon')', but
+   would also happen in cases such as `foo(traceon(`foo'))'.
+
+** Fix regression introduced in 1.4.7 where `m4 -N9' died with an assertion
+   failure.
+
+** Fix regression introduced in 1.4.11 where `defn' died with an assertion
+   failure on a traced but undefined macro.
+
+** New `-g'/`--gnu' command-line option overrides `-G'/`--traditional'.
+   For now, the environment variable POSIXLY_CORRECT has no effect on M4
+   behavior; but a future release of M4 will behave as though --traditional
+   is implied if POSIXLY_CORRECT is set (this future change is necessary,
+   because in the current release, there is no way to disable GNU
+   extensions that conflict with POSIX without the use of a non-POSIX
+   command-line argument).  Clients of M4 that want to use GNU extensions,
+   even when POSIXLY_CORRECT is set, should start using the -g command-line
+   argument, even though it is currently a no-op if -G did not appear
+   earlier in the command line, so that the client will not break in the
+   face of an upgraded m4 and a POSIXLY_CORRECT execution environment.
+
+** The `-L'/`--nesting-limit' command-line option now defaults to 0 for
+   unlimited on platforms that can detect and deal with stack overflow.  On
+   systems that lack alternate stack support, such as Cygwin, and on
+   systems that do not obey the POSIX semantics for distinguishing stack
+   overflow from other exceptions, such as Linux, you can optionally
+   install the libsigsegv library (version 2.6 or newer recommended) to
+   enhance m4's ability to accurately report stack overflow:
+   https://www.gnu.org/software/libsigsegv/
+
+** A number of portability improvements inherited from gnulib.
+
+* Noteworthy changes in Version 1.4.11 (2008-04-02) stable
+  Released by Eric Blake, based on git version 1.4.10a
+
+** Security fixes for the -F option, for bugs present since -F was
+   introduced in 1.3: Avoid core dump with 'm4 -F file -t undefined', and
+   avoid arbitrary code execution with certain file names.
+
+** Fix regression introduced in 1.4.9b in the `divert' builtin when more
+   than 512 kibibytes are saved in diversions on platforms like NetBSD
+   or darwin where fopen(name,"a+") seeks to the end of the file.
+
+** The output of the `maketemp' and `mkstemp' builtins is now quoted if a
+   file was created.  This is a minor security fix, because it was possible
+   (although rather unlikely) that an unquoted string could match an
+   existing macro name, such that use of the `mkstemp' output would trigger
+   inadvertent macro expansion and operate on the wrong file name.
+
+** Enhance the `defn' builtin to support concatenation of multiple text
+   arguments, as required by POSIX.  However, at this time, it is not
+   possible to concatenate a builtin macro with anything else; a warning is
+   now issued if this is attempted, although a future version of M4 may
+   lift this restriction to match other implementations.
+
+** Enhance the `format' builtin to parse all C99 floating point numbers,
+   even on platforms where strtod(3) is buggy, although the replacement
+   function does have the known issue of rounding errors when parsing
+   some decimal floating point values.  This fixes testsuite failures
+   introduced in 1.4.9b.
+
+** Enhance the `index' builtin to guarantee linear behavior, in spite of
+   the surprisingly large number of systems with a brain-dead quadratic
+   strstr(3).
+
+** A number of portability improvements inherited from gnulib.
+
+* Noteworthy changes in Version 1.4.10 (2007-07-09) stable
+  Released by Eric Blake, based on CVS version 1.4.9c
+
+** Upgrade from GPL version 2 to GPL version 3 or later.
+
+** A number of portability improvements inherited from gnulib.
+
+** Avoid undefined behavior introduced in 1.4.9b in the `format' builtin
+   when handling %c.  However, this area of code has never been documented,
+   and currently does not match the POSIX behavior of printf(1), so it may
+   have further changes in the next version.
+
+* Noteworthy changes in Version 1.4.9b (2007-05-29) beta
+  Released by Eric Blake, based on CVS version 1.4.9a
+
+** Fix regression introduced in 1.4.9 in the `eval' builtin when performing
+   division.
+
+** Fix regression introduced in 1.4.8 in the `-F' option that made it
+   impossible to freeze more than 512 kibibytes of diverted text.
+
+** The synclines option `-s' no longer generates sync lines in the middle of
+   multiline comments or quoted strings.
+
+** Work around a number of corner-case POSIX compliance bugs in various
+   broken stdio libraries.  In particular, the `syscmd' builtin behaves
+   more predictably when stdin is seekable.
+
+** The `format' builtin now understands formats such as %a, %A, and %'hhd,
+   and works around a number of platform printf bugs.  Furthermore, the
+   sequence format(%*.*d,-1,-1,1) no longer outputs random data.  However,
+   some non-compliant platforms such as mingw still have known bugs in
+   strtod that may cause testsuite failures.
+
+** The testsuite is improved to also run gnulib portability tests for the
+   features that M4 imports from gnulib.
+
+* Noteworthy changes in Version 1.4.9 (2007-03-23) stable
+  Released by Eric Blake, based on CVS version 1.4.8c
+
+** Minor documentation and portability cleanups.
+
+* Noteworthy changes in Version 1.4.8b (2007-02-24) beta
+  Released by Eric Blake, based on CVS version 1.4.8a
+
+** Fix a regression introduced in 1.4.8 that made m4 unable to process
+   files larger than 2GiB on some platforms.
+
+** Fix a regression introduced in 1.4.8 that made m4 dump core when
+   invoked as 'm4 -- file'.
+
+** The `eval' builtin now follows C precedence rules.  Additionally, the
+   short-circuit operators correctly short-circuit division by zero.  The
+   previously undocumented alias of '=' meaning '==' in eval now triggers a
+   deprecation warning, so that a future version of M4 can implement a form
+   of variable assignment as an extension.
+
+** The `include' builtin now affects exit status on failure, as required by
+   POSIX.  Use `sinclude' if you need a successful exit status.
+
+** The `-E'/`--fatal-warnings' command-line option now has two levels.  When
+   specified only once, warnings affect exit status, but execution
+   continues, so that you can see all warnings instead of fixing them one
+   at a time.  To achieve 1.4.8 behavior, where the first warning
+   immediately exits, specify -E twice on the command line.
+
+** A new `--warn-macro-sequence' command-line option allows detection of
+   sequences in `define' and `pushdef' definitions that match an optional
+   regular expression.  The default regular expression is
+   `\$${^}*}\|0-90-9+$', corresponding to the sequences that might
+   not behave correctly when upgrading to the eventual M4 2.0.  By default,
+   M4 2.0 will follow the POSIX requirement that a macro definition
+   containing `$11' must expand to the first argument concatenated with 1,
+   rather than the eleventh argument; and will take advantage of the POSIX
+   wording that allows implementations to treat `${11}' as the eleventh
+   argument instead of literal text.  Be aware that Autoconf 2.61 will not
+   work with this option enabled with the default regular expression; but
+   Autoconf 2.62 will be compatible with this option.
+
+** Improved portability to platforms such as BSD/OS and AIX.
+
+* Noteworthy changes in Version 1.4.8 (2006-11-20) stable
+  Released by Eric Blake, based on CVS version 1.4.7a
+
+** The `divert' macro and `-H'/`--hashsize' command line option no longer
+   cause a core dump when handed extra large values.  Also, `divert' now
+   uses memory proportional to the number of diversions in use, rather than
+   to the maximum diversion number encountered, so that large diversion
+   numbers are less likely to exhaust system memory; and is no longer
+   limited by the maximum number of file descriptors.
+
+** The `--help' and `--version' command line options now consistently
+   override all earlier options.  For example, `m4 --debugfile=trace
+   --help' now no longer accidentally creates an empty file `trace'.
+
+** The `-L'/`--nesting-limit' command line option can now be set to 0
+   to remove the default limit of 1024.  However, it is still possible that
+   heavily nested input can cause abrupt program termination due to stack
+   overflow.
+
+** Problems encountered when writing to standard error, such as with the
+   `errprint' macro, now always cause a non-zero exit status.
+
+** Warnings and errors issued during macro expansion are now consistently
+   reported at the line where the macro name was detected, rather than
+   where the close parenthesis resides.  Text wrapped by `m4wrap' now
+   remembers the location that was in effect when m4wrap was invoked,
+   rather than changing to line 0 and the empty string for a file.  The
+   macros `__line__' and `__file__' now work correctly even as the last
+   token in an included file.
+
+** The `builtin' and `indir' macros now transparently handle builtin
+   tokens generated by `defn'.
+
+** When diversions created by the `divert' macro collect enough text that
+   M4 must use temporary files, the environment variable $TMPDIR is now
+   consulted, and a better effort is made to clean up those files in the
+   event of a fatal signal.
+
+** The `mkstemp' builtin is added with the same GNU semantics as `maketemp',
+   based on the recommendation of POSIX to deprecate the POSIX semantics of
+   `maketemp' as inherently insecure.  In GNU mode (no -G supplied on the
+   command line), `maketemp' silently retains the secure GNU semantics, but
+   a future release of M4 will change this to emit a warning.  In
+   traditional mode (m4 -G), `maketemp' now uses the POSIX-mandated
+   insecure semantics, and issues a warning that you should convert your
+   script to use `mkstemp' instead.  Additionally, `mkstemp' and `maketemp'
+   are now well-defined even if the template argument does not end in six
+   `X' characters.
+
+** The manual has been improved, including a new section on a composite
+   macro `foreach'.
+
+** The `changecom' and `changequote' macros now treat an empty second
+   argument the same as if it were missing, rather than using the empty
+   string and making it impossible to end a comment or quote.
+
+** The `translit' macro now operates in linear instead of quadratic time,
+   and is now eight-bit clean.
+
+** The `-D', `-U', `-s', and `-t' command line options now take effect
+   after any files encountered earlier on the command line, rather than up
+   front, as is done in traditional implementations and required by POSIX.
+
+* Noteworthy changes in Version 1.4.7 (2006-09-25) stable
+  Released by Eric Blake, based on CVS version 1.4.6a
+
+** Fix regression from 1.4.5 in handling a file that ends in a macro
+   expansion without arguments instead of a newline.
+
+** The define and pushdef macros now warn when the first argument is not
+   a string, rather than silently doing nothing.
+
+** Standard input can now be read more than once, as in 'm4 - file -', and
+   is not closed until all wrapped text is handled.  This makes a
+   difference when stdin is not a regular file, and also fixes bugs when
+   using the syscmd or esyscmd macros from wrapped text.
+
+** When standard input is a seekable file, the m4exit, syscmd, and esyscmd
+   macros now restore the current position to the next unread byte rather
+   than discarding an arbitrary amount of buffered data.
+
+** SysV command-line compatibility is no longer a goal of GNU M4; the
+   focus will be instead on POSIX compatibility.  This release continues to
+   support previous usage, but adds warnings in areas which will allow a
+   future version of GNU M4 to use its own extensions without being tied to
+   the SysV command line interface.
+
+** The no-op compatibility command line options -B, -N, -S, -T, and
+   --diversions may be withdrawn or assigned new meanings in future
+   releases, so they now issue a warning if used.
+
+** A new command line option -i replaces the compatibility -e as the
+   short spelling of --interactive, for consistency with other GNU tools; a
+   warning is issued if the old spelling is used, and it may be assigned
+   new meaning in future releases.
+
+** A new command line option --debugfile replaces the options -o and
+   --error-output as the preferred spelling.  The old options were
+   misleading in their names and inconsistent with other GNU tools; they
+   are still silently accepted, but no longer documented in --help, and may
+   be assigned new meanings in future releases.
+
+* Noteworthy changes in Version 1.4.6 (2006-08-25) stable
+  Released by Eric Blake, based on CVS version 1.4.5a
+
+** Fix buffer overruns in regexp and patsubst macros when handed a trailing
+   backslash in the replacement text, or when handling \n substitutions
+   beyond the number of  groups.
+
+** Fix memory leak in regexp, patsubst, and changeword macros.
+
+** The format macro now understands %F, %g, and %G.
+
+** When loading frozen files, m4 now exits with status 63 if version
+   mismatch is detected.
+
+** Fix bugs that occurred when invoked with stdout or stderr closed,
+   and detect write failures to stdout or to the target of the debugfile
+   macro.  In particular, the syscmd and esyscmd macros can no longer
+   interfere with the debug stream or diversions.
+
+** The m4exit macro now converts values outside the range 0-255 to 1.
+
+** It is now an error if a command-line input file ends in the middle of a
+   comment, matching the behavior of mid-string and mid-argument
+   collection.
+
+** The dnl macro now warns if end of file is encountered instead of a
+   newline.
+
+** The error message when end of file is encountered now uses the file and
+   line where the dangling construct started, rather than `NONE:0:'.
+
+** The debugmode and __file__ macros, and the -s/--synclines option, now
+   show what directory a file was found in when the -I/--include option or
+   M4PATH variable had an effect.
+
+** The changequote and changecom macros now work with 8-bit characters, and
+   quotes and comments that begin with `(' are properly recognized
+   following a word.
+
+** The new macro __program__ is added, which allows the input file to issue
+   an error message that resembles messages from m4.  Warning and error
+   messages have been reformatted to comply with GNU Coding Standards.
+
+** The errprint, m4wrap, and shift macros are now recognized only with
+   arguments.
+
+** The index, substr, translit, regexp, and patsubst macros now produce
+   output when given only one argument, but still warn about a missing
+   second argument.
+
+** The patsubst macro now reliably finds zero-length matches at the end
+   of a string.
+
+* Noteworthy changes in Version 1.4.5 (2006-07-15) stable
+  Released by Eric Blake, based on CVS version 1.4.4c
+
+** Fix sysval on BeOS, OS/2, and other systems that store exit status
+   in the low-order byte.  Additionally, on Unix platforms, if syscmd was
+   terminated by a signal, sysval now displays the signal number shifted
+   left by eight bits, to match traditional m4 implementations.
+
+** The maketemp macro is no longer subject to platform limitations (such as
+   26 or 32 max files from a given template).
+
+** Frozen files now require that the first directive be V (version), to
+   better diagnose version mismatch.  Additionally, if the F directive
+   (builtin function) names an unknown builtin that existed in the m4 that
+   froze the file but not in the current m4 (for example, changeword), the
+   warning is deferred until an attempt is made to actually use the
+   builtin.  This allows downgrading from beta m4-1.4o to stable m4-1.4.5
+   without breaking autoconf.
+
+** The format and indir macros are now recognized only with arguments.
+
+** The eval macro no longer crashes on x86 architectures when dividing the
+   minimum integer by -1.
+
+** On systems with ecvt and fcvt, format no longer truncates trailing
+   zeroes on integers printed with %.0f.  On systems without these
+   functions, format is no longer subject to a buffer overflow that
+   permitted arbitrary code execution.
+
+** On native Windows builds, the macro __windows__ is provided instead of
+   __unix__.  Likewise, on OS/2 builds, the macro __os2__ is provided.
+   This allows input files to determine when syscmd might behave
+   differently.
+
+** Fix bug in 1.4.3 patch to use \n line-endings that did not work for
+   cygwin.
+
+** When given the empty string or 0, undivert is now documented as a no-op
+   rather than closing stdout, warning about a non-existent file, or trying
+   to read a directory as a file.
+
+** Many documentation improvements.  Also, the manual is now distributed
+   under FDL 1.2, rather than a stricter verbatim-only license.
+
+** Raise the -L (--nesting-limit) command line option limit from 250 to
+   1024.
+
+** The decr, incr, divert, m4exit, and substr macros treat an empty number
+   as 0, issue a warning, and expand as normal; rather than issuing an
+   error and expanding to the empty string.
+
+** The eval macro now treats an empty radix argument as 10, handles radix 1,
+   and treats the width argument as number of digits excluding the sign,
+   for compatibility with other m4 implementations.
+
+** The ifdef, divert, m4exit, substr, and translit macros now correctly
+   ignore extra arguments.
+
+** The popdef and undefine macros now correctly accept multiple arguments.
+
+** Although changeword is on its last leg, if enabled, it now reverts to the
+   default (faster) regexp when passed the empty string.
+
+** The regexp and substr macros now warn and ignore a trailing backslash in
+   the replacement, and warn on \n for n larger than the number of
+   sub-expressions in the regexp.
+
+* Noteworthy changes in Version 1.4.4b (2006-06-17) beta
+  Released by Eric Blake, based on CVS version 1.4.4a
+
+** Fix a recursive push_string crashing bug, which affected changequote of
+   three or more characters on some compilers.
+
+** Use automake to fix build portability issues.
+
+** Fix a recursive m4wrap crashing bug.
+
+** Fix a 1 in 2**32 hash crashing bug.
+
+** Tracing a macro by name is now persistent, even if the macro is
+   subsequently undefined or redefined.  The traceon and traceoff macros no
+   longer warn about undefined symbols.  This solves a crash when using
+   indir on an undefined macro traced with the -t option, as well as an
+   incorrect result of ifdef.  Furthermore, tracing is no longer
+   transferred with builtins, solving the bug of "m4 -tm4_eval" failing to
+   give trace output on the input
+   "define(`m4_eval',defn(`eval'))m4_eval(1)".
+
+** Fix a crash when a macro is undefined while collecting its arguments, by
+   always using the definition that was in effect before argument
+   collection.  This behavior matches the C pre-processor, and means that
+   the sequence "define(`f',`1')f(define(`f',`2'))f" is now documented to
+   result in "12", rather than the previously undocumented "22".
+
+** Update the regex engine to fix several bugs.
+
+** Fix a potential crash on machines where char is signed.
+
+* Noteworthy changes in Version 1.4.4 (Oct 2005) stable
+  Released by Gary V. Vaughan
+
+** ./configure --infodir=/usr/share/info now works correctly.
+
+** When any file named on the command line is missing exit with status 1.
+
+* Noteworthy changes in Version 1.4.3 (Mar 2005) stable
+  Released by Gary V. Vaughan
+
+** DESTDIR installs now work correctly.
+
+** Don't segfault with uncompilable regexps to changeword().
+
+** Always use \n line-endings for frozen files (fixes a Windows bug).
+
+** Portability fix for systems lacking mkstemp(3).
+
+** Approximately 20% speed up in the common case of usage with autoconf.
+
+** Supported on QNX 6.3.
+
+* Noteworthy changes in Version 1.4.2 (Aug 2004) stable
+  Released by Paul Eggert
+
+** No user visible changes; portability bug fixes only.
+
+* Noteworthy changes in Version 1.4.1 (Jun 2004) stable
+  Released by Paul Eggert
+
+** maketemp now creates an empty file with the given name, instead of merely
+   returning the name of a nonexistent file.  This closes a security hole.
+
+* Noteworthy changes in Version 1.4 (Oct 1994) stable
+  Released by Franc,ois Pinard
+
+** (No user visible changes)
+
+&#xc;
+Version 1.3 - September 1994, by Franc,ois Pinard
+
+* Diversions are created as needed.  Option `-N' is still accepted, but
+otherwise ignored.  Users should use only negative diversion numbers,
+instead of high positive numbers, for diverting to nowhere.
+
+* Diversions should also work faster.  No temporary files will be needed
+at all if all diversions taken altogether do not use more than 512K.
+
+* Frozen state files may be produced with the `--freeze-state' (-F)
+option and later brought back through the `--reload-state' (-R) option.
+&#xc;
+Version 1.2 - July 1994, by Franc,ois Pinard
+
+* In patsubst(STRING, REGEXP, REPLACEMENT), \& in REPLACEMENT has been
+changed to represent this part of STRING matched by the whole REGEXP,
+instead of the whole STRING as before.  \0 does the same, but emits a
+diagnostic saying it will disappear in some subsequent release.
+
+* eval(EXPR) emits a diagnostic if EXPR has suffixed crumb.  The same for
+other numeric conversions in incr(), decr(), divert(), etc.
+
+* `--fatal-warnings' (-E) stops execution at first warning.
+
+* `--nesting-limit=LEVEL' (-L LEVEL) sets a limit to macro nesting.
+It is initially fixed at 250.
+
+* `--word-regexp=REGEXP' (-W REGEXP) modifies macro name syntax, like
+does the new `changeword(REGEXP)' macro.  This feature is experimental,
+tell me your opinions about it.  You do need --enable-changeword at
+configure time to get these things.  Do *not* depend on them yet.
+
+* Trace output format is scannable by GNU Emacs' next-error function.
+
+* Stack overflow is detected and diagnosed on some capable systems.
+
+* Various bugs have been corrected, m4 should be more portable.  See the
+ChangeLog for details.
+&#xc;
+Version 1.1 - November 1993, by Franc,ois Pinard
+
+Changes which might affect existing GNU m4 scripts:
+
+* Option `-V' has been removed, use `--version' instead.  `--version'
+writes on standard output instead of standard error, and inhibits any
+script execution.
+
+* `--no-gnu-extensions' has been renamed `--traditional'.
+
+* In `eval', `^' used to indicate exponentiation, use `**' instead.
+
+* The automatic undiversion which takes place at end of all input is
+forced into the main output stream.
+
+Changes which are unlikely to affect existing scripts:
+
+* `--help' prints an usage summary on standard output.  Script execution
+is then inhibited.
+
+* `--prefix-builtins' (-P) prefixes all builtin macros by `m4_'.
+
+* Most builtin macros for which arguments are mandatory, called without
+any arguments, are no more recognized as builtin macros: they are
+consequently copied verbatim to the output stream.
+
+* `define' and `pushdef' are usable with only one argument, they give
+this argument an empty definition.
+
+* `eval' new operators for binary representation handling: `^' for
+exclusive-or, `~' for the bitwise negation, `<<' and `>>' for shifts.
+
+* `eval' recognizes the notation 0bDIGITS for binary numbers and the
+notation 0rRADIX:DIGITS for numbers in any radix from 1 to 36.
+&#xc;
+Version 1.0.3 - December 1992, by Franc,ois Pinard
+
+Changes for the user:
+
+* `dnl' outputs a diagnostic if immediately followed by `('.  Usually,
+`dnl' is followed by newline or whitespace.
+
+* `ifelse' accepts without complaining the common idiom of having only
+one argument.  This is useful for introducing long comments.
+
+* `eval' always expresses values as signed, whatever the radix.
+
+* M4OPTS environment variable is no longer obeyed.
+
+* `--no-warnings' option is renamed `--silent'.
+
+* Debug lines use a new format more compatible with GNU standards.
+
+* Various bugs have been corrected.  See the ChangeLog for details.
+
+Changes for the installer:
+
+* GNU m4 now uses an Autoconf-generated configure script, and should be
+more easily portable in many ways.  (Cray is not supported yet).
+
+* `make check' has been made more portable, expect no errors.
+
+Changes for the programmer:
+
+* Sources have been fully reindented to comply with GNU standards, and
+cleaned up in many ways.
+
+* Sources have been protoized.  Non-ANSI compilers are automatically
+detected, then sources are unprotoized on the fly before compilation.
+
+* GNU m4 uses newer versions of obstack, regex, getopt, etc.
+&#xc;
+Version 1.0 - October 1991, by René Seindal
+
+* Uses GNU configure, taken from the gdb distribution.
+
+* Uses GNU getopt(), with long option names.
+
+* The -Q/+quiet option is added, which suppresses warnings about missing
+or superflous arguments to built-in macros.
+
+* Added default options via the M4OPTS environment variable.
+
+* Several minor bugs have been fixed.
+&#xc;
+Version 0.99 - July 1991, by René Seindal
+
+* The builtins `incr' and `decr' are now implemented without use of
+`eval'.
+
+* The builtin `indir' is added, to allow for indirect macro calls
+(allows use of "illegal" macro names).
+
+* The debugging and tracing facilities has been enhanced considerably.
+See the manual for details.
+
+* The -tMACRO option is added, marks MACRO for tracing as soon as it
+is defined.
+
+* Builtins are traced after renaming iff they were before.
+
+* Named files can now be undiverted.
+
+* The -Nnum option can be used to increase the number of divertions
+available.
+
+* Calling changecom without arguments now disables all comment handling.
+
+* A bug in `dnl' is fixed.
+
+* A bug in the multi-character quoting code is fixed.
+
+* Several typos in the manual has been corrected.  More probably persist.
+&#xc;
+Version 0.75 - November 1990, by René Seindal
+
+* Implemented search path for include files (-I option and M4PATH
+environment variable).
+
+* Implemented builtin `format' for printf-like formatting.
+
+* Implemented builtin `regexp' for searching for regular expressions.
+
+* Implemented builtin `patsubst' for substitution with regular
+expressions.
+
+* Implemented builtin `esyscmd', which expands to a shell commands output.
+
+* Implemented `__file__' and `__line__' for use in error messages.
+
+* Implemented character ranges in `translit'.
+
+* Implemented control over debugging output.
+
+* Implemented multi-character quotes.
+
+* Implemented multi-character comment delimiters.
+
+* Changed predefined macro `gnu' to `__gnu__'.
+
+* Changed predefined macro `unix' to `__unix__', when the -G option is
+not used.  With -G, `unix' is still defined.
+
+* Added program name to error messages.
+
+* Fixed two missing null bytes bugs.
+&#xc;
+Version 0.50 - January 1990, by René Seindal
+
+* Initial beta release.

+GNU `m4' is an implementation of the traditional Unix macro
+processor.  It is mostly SVR4 compatible, although it has some
+extensions (for example, handling more than 9 positional parameters
+to macros).  `m4' also has built-in functions for including files,
+running shell commands, doing arithmetic, etc.  Autoconf needs GNU
+`m4' for generating `configure' scripts, but not for running them.
+
+GNU `m4' was originally written by René Seindal, from Denmark.
+This release is considered stable.
+
+If GNU `m4' is meant to serve GNU `autoconf', beware that `m4'
+should be fully installed *prior to* configuring `autoconf' itself.
+Likewise, if you intend on hacking GNU `m4' from git, the bootstrap
+process requires that you first install a released copy of GNU `m4'.
+
+If you are just trying to build `m4' from a released tarball, you
+should not normally need to run `./bootstrap' or `autoreconf'; just go
+ahead and start with `./configure'.  If you are trying to build `m4'
+from git, more information can be found in the version-control-only
+file HACKING.
+
+M4 has an optional dependency on the libsigsegv library:
+  https://www.gnu.org/software/libsigsegv/
+If the library has not been installed in the standard location, you
+can use `./configure --with-libsigsegv-prefix=/path/to/dir', to make
+the build of `m4' use /path/to/dir/include/sigsegv.h as appropriate.
+The use of this library is optional; the only difference in having it
+available is that it increases the number of platforms where `m4' can
+correctly distinguish stack overflow from an internal bug.  It is
+recommended that you use version 2.9 or newer.
+
+In the subdirectory `examples' you will find various m4 files, ranging
+from trivial test files to rather advanced macros.  If you intend to
+use m4 seriously, you might find useful material down there.
+
+See file `BACKLOG' for a summary of pending mail and articles.
+See file `COPYING' for copying conditions.  Note that M4 is distributed
+under the GNU Public License version 3 or later.  Some files in the
+distribution are copied from the gnulib project, and hence bear the
+designation version 2 or later because they are unmodified from gnulib;
+however, if you modify these files using M4 rather than gnulib as the
+source, you must update the license to be GPLv3 or later.
+See file `INSTALL' for compilation and installation instructions.
+See file `NEWS' for a list of major changes in the current release.
+See file `THANKS' for a list of contributors.
+
+By default, the `syscmd' and `esyscmd' macros try to use the first
+instance of `sh' found by `command -p getconf PATH' at configure time,
+with a default of `/bin/sh'.  If that default is inappropriate, you
+can use `./configure --with-syscmd-shell=location' to specify the
+shell to use.
+
+By using `./configure --enable-changeword', you get an experimental
+feature which allows for changing the syntax of what is a "word" in
+`m4'.  This feature will not be present in m4 2.0, but will be
+replaced by other new features which provide similar capability, so
+do not count on it.
+
+Send bug reports to `bug-m4@gnu.org'.  A bug report is an adequate
+description of the problem: your input, what you expected, what you got,
+and why this is wrong.  Diffs are welcome, but they only describe a
+solution, from which the problem might be uneasy to infer.
+
+For any copyright year range specified as YYYY-ZZZZ in this package
+note that the range specifies every single year in that closed interval.

+TODO file for GNU m4
+
+Tell <bug-m4@gnu.org> if you feel like volunteering for any
+of these ideas, listed more or less in decreasing order of priority.
+
+* Features or problems
+  - Fix format() builtin to handle %c more like printf(1) in the shell
+        http://lists.gnu.org/archive/html/bug-m4/2007-05/msg00047.html
+    Also, gnulib needs help to overcome mingw bugs related to format().
+  - Update documentation from accumulated mail about it
+  - Study synclines at the very beginning of each diverted sequence
+  - Make eval work on bignums - the 32 bits limit is artificial
+        From Krste Asanovic <krste@icsi.berkeley.edu>, 1993-03-20
+
+* Optimization and clean up
+  - Check for memory leaks and uninitialized reads
+        From Vern Paxson <vern@horse.ee.lbl.gov> on 1993-12-06
+  - Profile GNU m4 and speed it up
+        From David J. MacKenzie <djm@eng.umd.edu>, 1993-01-20
+
+        GNU m4 should be sped up by a factor of three for competing
+        with other versions (I think that the lexer is not agressive
+        enough and too often return single characters; obstacks might
+        be a little abused, too).
+  - Have NULs go really undisturbed through GNU m4
+        See `dumpdef' and debugging section, which abuses %s
+        From Thorsten Ohl <ohl@chico.harvard.edu>, 1992-12-21
+
+        path.c (add_include_directory): Why the '\0' terminator?
+
+        GNU m4 is lousy regarding NULs in streams (this would require
+        maintaining the string lengths, and avoiding strlen, strcpy,
+        etc.).

+# For projects using AC_CONFIG_AUX_DIR(foo), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative

+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*$.*$"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+# Bootstrap an Autotooled package from checked-out sources.
+# Written by Gary V. Vaughan, 2010
+# Inspired by a script written by Paul Eggert.

+
+## ------ ##
+## Usage. ##
+## ------ ##
+
+# Most GNUish projects do not keep all of the generated Autotool
+# files under version control, but running all of the right tools
+# with the right arguments, in the correct order to regenerate
+# all of those files in readiness for configuration and building
+# can be surprisingly involved!  Many projects have a 'bootstrap'
+# script under version control to invoke Autotools and perform
+# other assorted book-keeping with version numbers and the like.
+#
+# This bootstrap script aims to probe the configure.ac and top
+# Makefile.am of your project to automatically determine what
+# the correct ordering and arguments are and then run the tools for
+# you.  In order to use it, you can generate an initial standalone
+# script with:
+#
+#   gl/build-aux/inline-source gl/build-aux/bootstrap.in > bootstrap
+#
+# You should then store than script in version control for other
+# developers in you project.  It will give you instructions about
+# how to keep it up to date if the sources change.
+#
+# See gl/doc/bootstrap.texi for documentation on how to write
+# a bootstrap.conf to customize it for your project's
+# idiosyncracies.

+#   i) func_quote_arg_result
+#      double-quoted (when needed), suitable for a subsequent eval
+#  ii) func_quote_arg_unquoted_result
+#      has all characters that are still active within double
+#      quotes backslashified.  Available only if 'unquoted' is specified.
+#
+# Available modes:
+# ----------------
+# 'eval' (default)
+#       - escape shell special characters
+# 'expand'
+#       - the same as 'eval';  but do not quote variable references
+# 'pretty'
+#       - request aesthetic output, i.e. '"a b"' instead of 'a\ b'.  This might
+#         be used later in func_quote to get output like: 'echo "a b"' instead
+#         of 'echo a\ b'.  This is slower than default on some shells.
+# 'unquoted'
+#       - produce also $func_quote_arg_unquoted_result which does not contain
+#         wrapping double-quotes.
+#
+# Examples for 'func_quote_arg pretty,unquoted string':
+#
+#   string      | *_result              | *_unquoted_result
+#   ------------+-----------------------+-------------------

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# Copyright'.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug in processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath OPTION...'

+# Short help message in response to '-h' and '--help'.  Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+- a version-controlled .prev-version file
+- a NEWS file, with line 3 identical to this:

+discussion:
+  https://www.gnu.org/prep/maintain_toc.html
+
+Options:
+  --email ADR use ADR as contact in generated web pages; always give this.

+  -s SRCFILE   read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
+  -o OUTDIR    write files into OUTDIR, instead of manual/.
+  -I DIR       append DIR to the Texinfo search path.
+  --common ARG pass ARG in all invocations.
+  --html ARG   pass ARG to makeinfo or texi2html for HTML targets,
+                 instead of '$htmlarg'.
+  --info ARG   pass ARG to makeinfo for Info, instead of --no-split.

+  --version    display version information and exit successfully.
+
+Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"
+
+Typical sequence:
+  cd PACKAGESOURCE/doc
+  wget \"$scripturl\"
+  wget \"$templateurl\"
+  $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
+
+Output will be in a new subdirectory \"manual\" (by default;
+use -o OUTDIR to override).  Move all the new files into your web CVS
+tree, as explained in the Web Pages node of maintain.texi.
+
+Please use the --email ADDRESS option so your own bug-reporting
+address will be used in the generated HTML pages.
+
+MANUAL-TITLE is included as part of the HTML <title> of the overall
+manual/index.html file.  It should include the name of the package being
+documented.  manual/index.html is created by substitution from the file
+$GENDOCS_TEMPLATE_DIR/gendocs_template.  (Feel free to modify the
+generic template for your own purposes.)
+
+If you have several manuals, you'll need to run this script several
+times with different MANUAL values, specifying a different output
+directory with -o each time.  Then write (by hand) an overall index.html
+with links to them all.
+
+If a manual's Texinfo sources are spread across several directories,
+first copy or symlink all Texinfo sources into a single directory.
+(Part of the script's work is to make a tar.gz of the sources.)
+
+As implied above, by default monolithic Info files are generated.
+If you want split Info, or other Info options, use --info to override.
+
+You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML,
+and PERL to control the programs that get executed, and
+GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
+looked for.  With --docbook, the environment variables DOCBOOK2HTML,
+DOCBOOK2PDF, and DOCBOOK2TXT are also consulted.
+
+By default, makeinfo and texi2dvi are run in the default (English)
+locale, since that's the language of most Texinfo manuals.  If you
+happen to have a non-English manual and non-English web site, see the
+SETLANG setting in the source.
+
+Email bug reports or enhancement requests to bug-gnulib@gnu.org.

+# This script is derived from GIT-VERSION-GEN from GIT: https://git-scm.com/.
+# It may be run two ways:
+# - from a git repository in which the "git describe" command below
+#   produces useful output (thus requiring at least one signed tag)
+# - from a non-git-repo directory containing a .tarball-version file, which
+#   presumes this script is invoked like "./git-version-gen .tarball-version".
+
+# In order to use intra-version strings in your project, you will need two
+# separate generated version string files:
+#
+# .tarball-version - present only in a distribution tarball, and not in
+#   a checked-out repository.  Created with contents that were learned at
+#   the last time autoconf was run, and used by git-version-gen.  Must not
+#   be present in either $(srcdir) or $(builddir) for git-version-gen to
+#   give accurate answers during normal development with a checked out tree,
+#   but must be present in a tarball when there is no version control system.
+#   Therefore, it cannot be used in any dependencies.  GNUmakefile has
+#   hooks to force a reconfigure at distribution time to get the value
+#   correct, without penalizing normal development with extra reconfigures.
+#
+# .version - present in a checked-out repository and in a distribution
+#   tarball.  Usable in dependencies, particularly for files that don't
+#   want to depend on config.h but do want to track version changes.
+#   Delete this file prior to any autoconf run where you want to rebuild
+#   files to pick up a version string change; and leave it stale to
+#   minimize rebuild time after unrelated changes to configure sources.
+#
+# As with any generated file in a VC'd directory, you should add
+# /.version to .gitignore, so that you don't accidentally commit it.
+# .tarball-version is never generated in a VC'd directory, so needn't
+# be listed there.
+#
+# Use the following line in your configure.ac, so that $(VERSION) will
+# automatically be up-to-date each time configure is run (and note that
+# since configure.ac no longer includes a version string, Makefile rules
+# should not depend on configure.ac for version updates).
+#
+# AC_INIT(GNU project,
+#         m4_esyscmd(build-aux/git-version-gen .tarball-version),
+#         bug-project@example)
+#
+# Then use the following lines in your Makefile.am, so that .version
+# will be present for dependencies, and so that .version and
+# .tarball-version will exist in distribution tarballs.
+#

+
+OPTIONS:
+
+   --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+                  makes a change to SHA1's commit log text or metadata.
+   --append-dot append a dot to the first line of each commit message if
+                  there is no other punctuation or blank at the end.
+   --no-cluster never cluster commit messages under the same date/author
+                  header; the default is to cluster adjacent commit messages
+                  if their headers are the same and neither commit message
+                  contains multiple paragraphs.
+   --srcdir=DIR the root of the source tree, from which the .git/
+                  directory can be derived.
+   --since=DATE convert only the logs since DATE;
+                  the default is to convert all log entries.
+   --until=DATE convert only the logs older than DATE.
+   --ignore-matching=PAT ignore commit messages whose first lines match PAT.
+   --ignore-line=PAT ignore lines of commit messages that match PAT.
+   --format=FMT set format string for commit subject and body;
+                  see 'man git-log' for the list of format metacharacters;
+                  the default is '%s%n%b%n'
+   --strip-tab  remove one additional leading TAB from commit message lines.
+   --strip-cherry-pick  remove data inserted by "git cherry-pick";
+                  this includes the "cherry picked from commit ..." line,
+                  and the possible final "Conflicts:" paragraph.
+   --help       display this help and exit
+   --version    output version information and exit
+

+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line.  They are not copied to the output.
+
+  Copyright-paperwork-exempt: Yes
+    Append the "(tiny change)" notation to the usual "date name email"
+    ChangeLog header to mark a change that does not require a copyright
+    assignment.
+  Co-authored-by: Joe User <user\@example.com>
+    List the specified name and email address on a second
+    ChangeLog header, denoting a co-author.
+  Signed-off-by: Joe User <user\@example.com>
+    These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code.  Pairs must be separated by one or
+more blank line.

+Usage: $ME
+
+Run this script from top_srcdir (no arguments) after each non-alpha
+release, to update the web documentation at
+https://www.gnu.org/software/\$pkg/manual/
+
+This script assumes you're using git for revision control, and
+requires a .prev-version file as well as a Makefile, from which it
+extracts the version number and package name, respectively.  Also, it
+assumes all documentation is in the doc/ sub-directory.
+
+Options:
+  -C, --builddir=DIR  location of (configured) Makefile (default: .)
+  -n, --dry-run       don't actually commit anything
+  -m, --mirror        remove out of date files from document server
+  -u, --user          the name of the CVS user on Savannah
+  --help              print this help, then exit

+usage="Usage: $0 OPTION... CMD FILE... CMD FILE...
+
+Sign all FILES, and process them at the destinations specified with --to.
+If CMD is not given, it defaults to uploading.  See examples below.
+
+Commands:
+  --delete                 delete FILES from destination
+  --symlink                create symbolic links
+  --rmsymlink              remove symbolic links
+  --                       treat the remaining arguments as files to upload
+
+Options:
+  --to DEST                specify a destination DEST for FILES
+                           (multiple --to options are allowed)
+  --user NAME              sign with key NAME
+  --replace                allow replacements of existing files
+  --symlink-regex=EXPR   use sed script EXPR to compute symbolic link names
+  -n, --dry-run            do nothing, show what would have been done
+                           (including the constructed directive file)
+  --version                output version information and exit
+  -h, --help               print this help text and exit
+
+If --symlink-regex is given without EXPR, then the link target name
+is created by replacing the version information with '-latest', e.g.:
+  foo-1.3.4.tar.gz -> foo-latest.tar.gz
+
+Recognized destinations are:
+  alpha.gnu.org:DIRECTORY
+  savannah.gnu.org:DIRECTORY
+  savannah.nongnu.org:DIRECTORY
+  ftp.gnu.org:DIRECTORY
+                           build directive files and upload files by FTP
+  download.gnu.org.ua:{alpha|ftp}/DIRECTORY
+                           build directive files and upload files by SFTP
+  user@host:DIRECTORY    upload files with scp
+
+Options and commands are applied in order.  If the file $conffile exists
+in the current working directory, its contents are prepended to the
+actual command line options.  Use this to keep your defaults.  Comments
+(#) and empty lines in $conffile are allowed.
+
+<https://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
+gives some further background.
+
+Examples:
+1. Upload foobar-1.0.tar.gz to ftp.gnu.org:
+  gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
+
+2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
+  gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+3. Same as above, and also create symbolic links to foobar-latest.tar.*:
+  gnupload --to ftp.gnu.org:foobar \\
+           --symlink-regex \\
+           foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+4. Create a symbolic link foobar-latest.tar.gz -> foobar-1.0.tar.gz
+   and likewise for the corresponding .sig file:
+  gnupload --to ftp.gnu.org:foobar \\
+           --symlink foobar-1.0.tar.gz     foobar-latest.tar.gz \\
+                     foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
+  or (equivalent):
+  gnupload --to ftp.gnu.org:foobar \\
+           --symlink foobar-1.0.tar.gz     foobar-latest.tar.gz \\
+           --symlink foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
+
+5. Upload foobar-0.9.90.tar.gz to two sites:
+  gnupload --to alpha.gnu.org:foobar \\
+           --to sources.redhat.com:~ftp/pub/foobar \\
+           foobar-0.9.90.tar.gz
+
+6. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
+   (the -- terminates the list of files to delete):
+  gnupload --to alpha.gnu.org:foobar \\
+           --to sources.redhat.com:~ftp/pub/foobar \\
+           --delete oopsbar-0.9.91.tar.gz \\
+           -- foobar-0.9.91.tar.gz
+
+gnupload executes a program ncftpput to do the transfers; if you don't
+happen to have an ncftp package installed, the ncftpput-ftp script in
+the build-aux/ directory of the gnulib package
+(https://savannah.gnu.org/projects/gnulib) may serve as a replacement.

+% of date, so if that's what you're using, please check.

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+# Written by Jim Meyering and Joel E. Denny
+
+# This script updates an FSF copyright year list to include the current year.
+# Usage: update-copyright FILE...
+#
+# The arguments to this script should be names of files that contain
+# copyright statements to be updated.  The copyright holder's name
+# defaults to "Free Software Foundation, Inc." but may be changed to
+# any other name by using the "UPDATE_COPYRIGHT_HOLDER" environment
+# variable.
+#
+# For example, you might wish to use the update-copyright target rule
+# in maint.mk from gnulib's maintainer-makefile module.
+#
+# Iff a copyright statement is recognized in a file and the final
+# year is not the current year, then the statement is updated for the
+# new year and it is reformatted to:
+#
+#   1. Fit within 72 columns.
+#   2. Convert 2-digit years to 4-digit years by prepending "19".
+#   3. Expand copyright year intervals.  (See "Environment variables"
+#      below.)
+#
+# A warning is printed for every file for which no copyright
+# statement is recognized.
+#
+# Each file's copyright statement must be formatted correctly in
+# order to be recognized.  For example, each of these is fine:
+#
+#   Copyright @copyright{} 1990-2005, 2007-2009 Free Software
+#   Foundation, Inc.
+#
+#   # Copyright (C) 1990-2005, 2007-2009 Free Software
+#   # Foundation, Inc.
+#
+#   /*
+#    * Copyright &copy; 90,2005,2007-2009
+#    * Free Software Foundation, Inc.
+#    */
+#
+# However, the following format is not recognized because the line
+# prefix changes after the first line:
+#
+#   ## Copyright (C) 1990-2005, 2007-2009 Free Software
+#   #  Foundation, Inc.
+#
+# However, any correctly formatted copyright statement following
+# a non-matching copyright statements would be recognized.
+#
+# The exact conditions that a file's copyright statement must meet
+# to be recognized are:
+#
+#   1. It is the first copyright statement that meets all of the
+#      following conditions.  Subsequent copyright statements are
+#      ignored.
+#   2. Its format is "Copyright (C)", then a list of copyright years,
+#      and then the name of the copyright holder.
+#   3. The "(C)" takes one of the following forms or is omitted
+#      entirely:
+#
+#        A. (C)
+#        B. (c)
+#        C. @copyright{}
+#        D. &copy;
+#        E. ©
+#
+#   4. The "Copyright" appears at the beginning of a line, except that it
+#      may be prefixed by any sequence (e.g., a comment) of no more than
+#      5 characters -- including white space.
+#   5. Iff such a prefix is present, the same prefix appears at the
+#      beginning of each remaining line within the FSF copyright
+#      statement.  There is one exception in order to support C-style
+#      comments: if the first line's prefix contains nothing but
+#      whitespace surrounding a "/*", then the prefix for all subsequent
+#      lines is the same as the first line's prefix except with each of
+#      "/" and possibly "*" replaced by a " ".  The replacement of "*"
+#      by " " is consistent throughout all subsequent lines.
+#   6. Blank lines, even if preceded by the prefix, do not appear
+#      within the FSF copyright statement.
+#   7. Each copyright year is 2 or 4 digits, and years are separated by
+#      commas, "-", or "--".  Whitespace may appear after commas.
+#
+# Environment variables:
+#
+#   1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement
+#      is reformatted even if it does not need updating for the new
+#      year.  If unset or set to 0, only updated FSF copyright

+;;; I often refill paragraphs inside C comments, while stretching or
+;;; shrinking the surrounding box as needed.  This is a real pain to
+;;; do by hand.  Here is the code I made to ease my life on this,
+;;; usable from within GNU Emacs.  It would not be fair giving all
+;;; sources for a product without also giving the means for nicely
+;;; modifying them.
+;;;
+;;; The function rebox-c-comment adjust comment boxes without
+;;; refilling comment paragraphs, while reindent-c-comment adjust
+;;; comment boxes after refilling.  Numeric prefixes are used to add,
+;;; remove, or change the style of the box surrounding the comment.
+;;; Since refilling paragraphs in C mode does make sense only for
+;;; comments, this code redefines the M-q command in C mode.  I use
+;;; this hack by putting, in my .emacs file:
+;;;
+;;;	(setq c-mode-hook
+;;;	      '(lambda ()
+;;;		 (define-key c-mode-map "\M-q" 'reindent-c-comment)))
+;;;	(autoload 'rebox-c-comment "c-boxes" nil t)
+;;;	(autoload 'reindent-c-comment "c-boxes" nil t)
+;;;
+;;; The cursor should be within a comment before any of these
+;;; commands, or else it should be between two comments, in which case
+;;; the command applies to the next comment.  When the command is
+;;; given without prefix, the current comment box type is recognized
+;;; and preserved.  Given 0 as a prefix, the comment box disappears
+;;; and the comment stays between a single opening `/*' and a single
+;;; closing `*/'.  Given 1 or 2 as a prefix, a single or doubled lined
+;;; comment box is forced.  Given 3 as a prefix, a Taarna style box is
+;;; forced, but you do not even want to hear about those.  When a
+;;; negative prefix is given, the absolute value is used, but the
+;;; default style is changed.  Any other value (like C-u alone) forces
+;;; the default box style.
+;;;
+;;; I observed rounded corners first in some code from Warren Tucker

+\`configure' configures GNU M4 1.4.19 to adapt to many kinds of systems.
+
+Usage: $0 OPTION... VAR=VALUE...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE disabled
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR configure dir or \`..'
+
+Installation directories:

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          PREFIX
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+                          (use with caution on other systems).
+  --with-libsigsegv       use the GNU libsigsegv library, when present,
+                          instead of the gnulib module 'sigsegv'
+  --with-libsigsegv-prefix=DIR  search for libsigsegv in DIR/include and DIR/lib
+  --without-libsigsegv-prefix     don't search for libsigsegv in includedir and libdir

+  --with-libintl-prefix=DIR  search for libintl in DIR/include and DIR/lib
+  --without-libintl-prefix     don't search for libintl in includedir and libdir
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, La@TeX{} input
+format, SGML or XML using a publicly available
+DTD, and standard-conforming simple HTML,
+PostScript or PDF designed for human modification.  Examples
+of transparent image formats include PNG, XCF and
+JPG@.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, SGML or
+XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML,
+PostScript or PDF produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:

+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+@uref{https://www.gnu.org/licenses/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+
+@heading Preamble
+
+The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom
+to share and change all versions of a program---to make sure it remains
+free software for all its users.  We, the Free Software Foundation,
+use the GNU General Public License for most of our software; it
+applies also to any other work released this way by its authors.  You
+can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you
+have certain responsibilities if you distribute copies of the
+software, or if you modify it: responsibilities to respect the freedom
+of others.
+
+For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too,
+receive or can get the source code.  And you must show them these
+terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the
+manufacturer can do so.  This is fundamentally incompatible with the
+aim of protecting users' freedom to change the software.  The
+systematic pattern of such abuse occurs in the area of products for
+individuals to use, which is precisely where it is most unacceptable.
+Therefore, we have designed this version of the GPL to prohibit the
+practice for those products.  If such problems arise substantially in
+other domains, we stand ready to extend this provision to those
+domains in future versions of the GPL, as needed to protect the
+freedom of users.
+
+Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish
+to avoid the special danger that patents applied to a free program
+could make it effectively proprietary.  To prevent this, the GPL
+assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+@heading TERMS AND CONDITIONS
+
+@enumerate 0
+@item Definitions.
+
+``This License'' refers to version 3 of the GNU General Public License.
+
+``Copyright'' also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+
+``The Program'' refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as ``you''.  ``Licensees'' and
+``recipients'' may be individuals or organizations.
+
+To ``modify'' a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of
+an exact copy.  The resulting work is called a ``modified version'' of
+the earlier work or a work ``based on'' the earlier work.
+
+A ``covered work'' means either the unmodified Program or a work based
+on the Program.
+
+To ``propagate'' a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To ``convey'' a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user
+through a computer network, with no transfer of a copy, is not
+conveying.
+
+An interactive user interface displays ``Appropriate Legal Notices'' to
+the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+@item Source Code.
+
+The ``source code'' for a work means the preferred form of the work for
+making modifications to it.  ``Object code'' means any non-source form
+of a work.
+
+A ``Standard Interface'' means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The ``System Libraries'' of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+``Major Component'', in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The ``Corresponding Source'' for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can
+regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same
+work.
+
+@item Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey,
+without conditions so long as your license otherwise remains in force.
+You may convey covered works to others for the sole purpose of having
+them make modifications exclusively for you, or provide you with
+facilities for running those works, provided that you comply with the
+terms of this License in conveying all material for which you do not
+control copyright.  Those thus making or running the covered works for
+you must do so exclusively on your behalf, under your direction and
+control, on terms that prohibit them from making any copies of your
+copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the
+conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+@item Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such
+circumvention is effected by exercising rights under this License with
+respect to the covered work, and you disclaim any intention to limit
+operation or modification of the work as a means of enforcing, against
+the work's users, your or third parties' legal rights to forbid
+circumvention of technological measures.
+
+@item Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+@item Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these
+conditions:
+
+@enumerate a
+@item
+The work must carry prominent notices stating that you modified it,
+and giving a relevant date.
+
+@item
+The work must carry prominent notices stating that it is released
+under this License and any conditions added under section 7.  This
+requirement modifies the requirement in section 4 to ``keep intact all
+notices''.
+
+@item
+You must license the entire work, as a whole, under this License to
+anyone who comes into possession of a copy.  This License will
+therefore apply, along with any applicable section 7 additional terms,
+to the whole of the work, and all its parts, regardless of how they
+are packaged.  This License gives no permission to license the work in
+any other way, but it does not invalidate such permission if you have
+separately received it.
+
+@item
+If the work has interactive user interfaces, each must display
+Appropriate Legal Notices; however, if the Program has interactive
+interfaces that do not display Appropriate Legal Notices, your work
+need not make them do so.
+@end enumerate
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+``aggregate'' if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+@item  Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of
+sections 4 and 5, provided that you also convey the machine-readable
+Corresponding Source under the terms of this License, in one of these
+ways:
+
+@enumerate a
+@item
+Convey the object code in, or embodied in, a physical product
+(including a physical distribution medium), accompanied by the
+Corresponding Source fixed on a durable physical medium customarily
+used for software interchange.
+
+@item
+Convey the object code in, or embodied in, a physical product
+(including a physical distribution medium), accompanied by a written
+offer, valid for at least three years and valid for as long as you
+offer spare parts or customer support for that product model, to give
+anyone who possesses the object code either (1) a copy of the
+Corresponding Source for all the software in the product that is
+covered by this License, on a durable physical medium customarily used
+for software interchange, for a price no more than your reasonable
+cost of physically performing this conveying of source, or (2) access
+to copy the Corresponding Source from a network server at no charge.
+
+@item
+Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source.  This alternative is
+allowed only occasionally and noncommercially, and only if you
+received the object code with such an offer, in accord with subsection
+6b.
+
+@item
+Convey the object code by offering access from a designated place
+(gratis or for a charge), and offer equivalent access to the
+Corresponding Source in the same way through the same place at no
+further charge.  You need not require recipients to copy the
+Corresponding Source along with the object code.  If the place to copy
+the object code is a network server, the Corresponding Source may be
+on a different server (operated by you or a third party) that supports
+equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source.
+Regardless of what server hosts the Corresponding Source, you remain
+obligated to ensure that it is available for as long as needed to
+satisfy these requirements.
+
+@item
+Convey the object code using peer-to-peer transmission, provided you
+inform other peers where the object code and Corresponding Source of
+the work are being offered to the general public at no charge under
+subsection 6d.
+
+@end enumerate
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A ``User Product'' is either (1) a ``consumer product'', which means any
+tangible personal property which is normally used for personal,
+family, or household purposes, or (2) anything designed or sold for
+incorporation into a dwelling.  In determining whether a product is a
+consumer product, doubtful cases shall be resolved in favor of
+coverage.  For a particular product received by a particular user,
+``normally used'' refers to a typical or common use of that class of
+product, regardless of the status of the particular user or of the way
+in which the particular user actually uses, or expects or is expected
+to use, the product.  A product is a consumer product regardless of
+whether the product has substantial commercial, industrial or
+non-consumer uses, unless such uses represent the only significant
+mode of use of the product.
+
+``Installation Information'' for a User Product means any methods,
+procedures, authorization keys, or other information required to
+install and execute modified versions of a covered work in that User
+Product from a modified version of its Corresponding Source.  The
+information must suffice to ensure that the continued functioning of
+the modified object code is in no case prevented or interfered with
+solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or
+updates for a work that has been modified or installed by the
+recipient, or for the User Product in which it has been modified or
+installed.  Access to a network may be denied when the modification
+itself materially and adversely affects the operation of the network
+or violates the rules and protocols for communication across the
+network.
+
+Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+@item Additional Terms.
+
+``Additional permissions'' are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders
+of that material) supplement the terms of this License with terms:
+
+@enumerate a
+@item
+Disclaiming warranty or limiting liability differently from the terms
+of sections 15 and 16 of this License; or
+
+@item
+Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices
+displayed by works containing it; or
+
+@item
+Prohibiting misrepresentation of the origin of that material, or
+requiring that modified versions of such material be marked in
+reasonable ways as different from the original version; or
+
+@item
+Limiting the use for publicity purposes of names of licensors or
+authors of the material; or
+
+@item
+Declining to grant rights under trademark law for use of some trade
+names, trademarks, or service marks; or
+
+@item
+Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with
+contractual assumptions of liability to the recipient, for any
+liability that these contractual assumptions directly impose on those
+licensors and authors.
+@end enumerate
+
+All other non-permissive additional terms are considered ``further
+restrictions'' within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions; the
+above requirements apply either way.
+
+@item Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+@item Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run
+a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+@item Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+An ``entity transaction'' is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+@item Patents.
+
+A ``contributor'' is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's ``contributor version''.
+
+A contributor's ``essential patent claims'' are all patent claims owned
+or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, ``control'' includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a ``patent license'' is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To ``grant'' such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  ``Knowingly relying'' means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is ``discriminatory'' if it does not include within the
+scope of its coverage, prohibits the exercise of, or is conditioned on
+the non-exercise of one or more of the rights that are specifically
+granted under this License.  You may not convey a covered work if you
+are a party to an arrangement with a third party that is in the
+business of distributing software, under which you make payment to the
+third party based on the extent of your activity of conveying the
+work, and under which the third party grants, to any of the parties
+who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by
+you (or copies made from those copies), or (b) primarily for and in
+connection with specific products or compilations that contain the
+covered work, unless you entered into that arrangement, or that patent
+license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+@item No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey
+a covered work so as to satisfy simultaneously your obligations under
+this License and any other pertinent obligations, then as a
+consequence you may not convey it at all.  For example, if you agree
+to terms that obligate you to collect a royalty for further conveying
+from those to whom you convey the Program, the only way you could
+satisfy both those terms and this License would be to refrain entirely
+from conveying the Program.
+
+@item Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+@item Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions
+of the GNU General Public License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies that a certain numbered version of the GNU General Public
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that numbered version or
+of any later version published by the Free Software Foundation.  If
+the Program does not specify a version number of the GNU General
+Public License, you may choose any version ever published by the Free
+Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions
+of the GNU General Public License can be used, that proxy's public
+statement of acceptance of a version permanently authorizes you to
+choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+@item Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW@.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+A PARTICULAR PURPOSE@.  THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU@.  SHOULD THE PROGRAM PROVE
+DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+@item Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
+LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
+TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+@item Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+@end enumerate
+
+@heading END OF TERMS AND CONDITIONS
+
+@heading How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.
+
+@smallexample
+@var{one line to give the program's name and a brief idea of what it does.}
+Copyright (C) @var{year} @var{name of author}
+
+This program is free software: you can redistribute it and/or modify
+it under the terms of the GNU General Public License as published by
+the Free Software Foundation, either version 3 of the License, or (at
+your option) any later version.
+
+This program is distributed in the hope that it will be useful, but
+WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE@.  See the GNU
+General Public License for more details.
+
+You should have received a copy of the GNU General Public License
+along with this program.  If not, see @url{https://www.gnu.org/licenses/}.
+@end smallexample
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+@smallexample
+@var{program} Copyright (C) @var{year} @var{name of author}
+This program comes with ABSOLUTELY NO WARRANTY; for details type @samp{show w}.
+This is free software, and you are welcome to redistribute it
+under certain conditions; type @samp{show c} for details.
+@end smallexample
+
+The hypothetical commands @samp{show w} and @samp{show c} should show
+the appropriate parts of the General Public License.  Of course, your
+program's commands might be different; for a GUI interface, you would
+use an ``about box''.
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a ``copyright disclaimer'' for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+@url{https://www.gnu.org/licenses/}.
+
+The GNU General Public License does not permit incorporating your
+program into proprietary programs.  If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library.  If this is what you want to do, use
+the GNU Lesser General Public License instead of this License.  But
+first, please read @url{https://www.gnu.org/licenses/why-not-lgpl.html}.

+
+   GNU ‘m4’ is an implementation of the traditional UNIX macro
+processor.  It is mostly SVR4 compatible, although it has some
+extensions (for example, handling more than 9 positional parameters to
+macros).  ‘m4’ also has builtin functions for including files, running
+shell commands, doing arithmetic, etc.  Autoconf needs GNU ‘m4’ for
+generating ‘configure’ scripts, but not for running them.
+
+   GNU ‘m4’ was originally written by René Seindal, with subsequent
+changes by François Pinard and other volunteers on the Internet.  All
+names and email addresses can be found in the files ‘m4-1.4.19/AUTHORS’
+and ‘m4-1.4.19/THANKS’ from the GNU M4 distribution.
+
+   This is release 1.4.19.  It is now considered stable: future releases
+in the 1.4.x series are only meant to fix bugs, increase speed, or
+improve documentation.  However...
+
+   An experimental feature, which would improve ‘m4’ usefulness, allows
+for changing the syntax for what is a “word” in ‘m4’.  You should use:
+     ./configure --enable-changeword
+if you want this feature compiled in.  The current implementation slows
+down ‘m4’ considerably and is hardly acceptable.  In the future, ‘m4’
+2.0 will come with a different set of new features that provide similar
+capabilities, but without the inefficiencies, so changeword will go away
+and _you should not count on it_.

+
+1.1 Introduction to ‘m4’
+========================
+
+‘m4’ is a macro processor, in the sense that it copies its input to the
+output, expanding macros as it goes.  Macros are either builtin or
+user-defined, and can take any number of arguments.  Besides just doing
+macro expansion, ‘m4’ has builtin functions for including named files,
+running shell commands, doing integer arithmetic, manipulating text in
+various ways, performing recursion, etc.... ‘m4’ can be used either as a
+front-end to a compiler, or as a macro processor in its own right.
+
+   The ‘m4’ macro processor is widely available on all UNIXes, and has
+been standardized by POSIX. Usually, only a small percentage of users
+are aware of its existence.  However, those who find it often become
+committed users.  The popularity of GNU Autoconf, which requires GNU
+‘m4’ for _generating_ ‘configure’ scripts, is an incentive for many to
+install it, while these people will not themselves program in ‘m4’.  GNU
+‘m4’ is mostly compatible with the System V, Release 4 version, except
+for some minor differences.  *Note Compatibility::, for more details.
+
+   Some people find ‘m4’ to be fairly addictive.  They first use ‘m4’
+for simple problems, then take bigger and bigger challenges, learning
+how to write complex sets of ‘m4’ macros along the way.  Once really
+addicted, users pursue writing of sophisticated ‘m4’ applications even
+to solve simple problems, devoting more time debugging their ‘m4’
+scripts than doing real work.  Beware that ‘m4’ may be dangerous for the
+health of compulsive programmers.

+
+1.2 Historical references
+=========================
+
+Macro languages were invented early in the history of computing.  In the
+1950s Alan Perlis suggested that the macro language be independent of
+the language being processed.  Techniques such as conditional and
+recursive macros, and using macros to define other macros, were
+described by Doug McIlroy of Bell Labs in “Macro Instruction Extensions
+of Compiler Languages”, _Communications of the ACM_ 3, 4 (1960), 214–20,
+<https://dl.acm.org/doi/10.1145/367177.367223>.
+
+   An important precursor of ‘m4’ was GPM; see C. Strachey, “A general
+purpose macrogenerator”, _Computer Journal_ 8, 3 (1965), 225–41,
+<https://academic.oup.com/comjnl/article/8/3/225/336044>.  GPM is also
+succinctly described in David Gries’s book _Compiler Construction for
+Digital Computers_, Wiley (1971).  Strachey was a brilliant programmer:
+GPM fit into 250 machine instructions!
+
+   Inspired by GPM while visiting Strachey’s Lab in 1968, McIlroy wrote
+a model preprocessor in that fit into a page of Snobol 3 code, and
+McIlroy and Robert Morris developed a series of further models at Bell
+Labs.  Andrew D. Hall followed up with M6, a general purpose macro
+processor used to port the Fortran source code of the Altran computer
+algebra system; see Hall’s “The M6 Macro Processor”, Computing Science
+Technical Report #2, Bell Labs (1972),
+<http://cm.bell-labs.com/cm/cs/cstr/2.pdf>.  M6’s source code consisted
+of about 600 Fortran statements.  Its name was the first of the ‘m4’
+line.
+
+   The Brian Kernighan and P.J. Plauger book _Software Tools_,
+Addison-Wesley (1976), describes and implements a Unix macro-processor
+language, which inspired Dennis Ritchie to write ‘m3’, a macro processor
+for the AP-3 minicomputer.
+
+   Kernighan and Ritchie then joined forces to develop the original
+‘m4’, described in “The M4 Macro Processor”, Bell Laboratories (1977),
+<https://wolfram.schneider.org/bsd/7thEdManVol2/m4/m4.pdf>.  It had only
+21 builtin macros.
+
+   While ‘GPM’ was more _pure_, ‘m4’ is meant to deal with the true
+intricacies of real life: macros can be recognized without being
+pre-announced, skipping whitespace or end-of-lines is easier, more
+constructs are builtin instead of derived, etc.
+
+   Originally, the Kernighan and Plauger macro-processor, and then ‘m3’,
+formed the engine for the Rational FORTRAN preprocessor, that is, the
+‘Ratfor’ equivalent of ‘cpp’.  Later, ‘m4’ was used as a front-end for
+‘Ratfor’, ‘C’ and ‘Cobol’.
+
+   René Seindal released his implementation of ‘m4’, GNU ‘m4’, in 1990,
+with the aim of removing the artificial limitations in many of the
+traditional ‘m4’ implementations, such as maximum line length, macro
+size, or number of macros.
+
+   The late Professor A. Dain Samples described and implemented a
+further evolution in the form of ‘M5’: “User’s Guide to the M5 Macro
+Language: 2nd edition”, Electronic Announcement on comp.compilers
+newsgroup (1992).
+
+   François Pinard took over maintenance of GNU ‘m4’ in 1992, until 1994
+when he released GNU ‘m4’ 1.4, which was the stable release for 10
+years.  It was at this time that GNU Autoconf decided to require GNU
+‘m4’ as its underlying engine, since all other implementations of ‘m4’
+had too many limitations.
+
+   More recently, in 2004, Paul Eggert released 1.4.1 and 1.4.2 which
+addressed some long standing bugs in the venerable 1.4 release.  Then in
+2005, Gary V. Vaughan collected together the many patches to GNU ‘m4’
+1.4 that were floating around the net and released 1.4.3 and 1.4.4.  And
+in 2006, Eric Blake joined the team and prepared patches for the release
+of 1.4.5, with subsequent releases through intervening years, as recent
+as 1.4.18 in 2016.
+
+   Meanwhile, development has continued on new features for ‘m4’, such
+as dynamic module loading and additional builtins.  When complete, GNU

+
+1.3 Problems and bugs
+=====================
+
+If you have problems with GNU M4 or think you’ve found a bug, please
+report it.  Before reporting a bug, make sure you’ve actually found a
+real bug.  Carefully reread the documentation and see if it really says
+you can do what you’re trying to do.  If it’s not clear whether you
+should be able to do something or not, report that too; it’s a bug in
+the documentation!
+
+   Before reporting a bug or trying to fix it yourself, try to isolate
+it to the smallest possible input file that reproduces the problem.
+Then send us the input file and the exact results ‘m4’ gave you.  Also
+say what you expected to occur; this will help us decide whether the
+problem was really in the documentation.
+
+   Once you’ve got a precise problem, send e-mail to <bug-m4@gnu.org>.
+Please include the version number of ‘m4’ you are using.  You can get
+this information with the command ‘m4 --version’.  Also provide details
+about the platform you are executing on.
+
+   Non-bug suggestions are always welcome as well.  If you have
+questions about things that are unclear in the documentation or are just
+obscure features, please report them too.

+File: m4.info,  Node: Manual,  Prev: Bugs,  Up: Preliminaries
+
+1.4 Using this manual
+=====================
+
+This manual contains a number of examples of ‘m4’ input and output, and
+a simple notation is used to distinguish input, output and error
+messages from ‘m4’.  Examples are set out from the normal text, and
+shown in a fixed width font, like this
+
+     This is an example of an example!
+
+   To distinguish input from output, all output from ‘m4’ is prefixed by
+the string ‘⇒’, and all error messages by the string ‘error→’.  When
+showing how command line options affect matters, the command line is
+shown with a prompt ‘$ ‘like this’’, otherwise, you can assume that a
+simple ‘m4’ invocation will work.  Thus:
+
+     $ command line to invoke m4
+     Example of input line
+     ⇒Output line from m4
+     error→and an error message
+
+   The sequence ‘^D’ in an example indicates the end of the input file.
+The sequence ‘<NL>’ refers to the newline character.  The majority of
+these examples are self-contained, and you can run them with similar
+results by invoking ‘m4 -d’.  In fact, the testsuite that is bundled in
+the GNU M4 package consists of the examples in this document!  Some of
+the examples assume that your current directory is located where you
+unpacked the installation, so if you plan on following along, you may
+find it helpful to do this now:
+
+     $ cd m4-1.4.19
+
+   As each of the predefined macros in ‘m4’ is described, a prototype
+call of the macro will be shown, giving descriptive names to the
+arguments, e.g.,
+
+ -- Composite: example (STRING, COUNT = ‘1’, ARGUMENT...)
+     This is a sample prototype.  There is not really a macro named
+     ‘example’, but this documents that if there were, it would be a
+     Composite macro, rather than a Builtin.  It requires at least one
+     argument, STRING.  Remember that in ‘m4’, there must not be a space
+     between the macro name and the opening parenthesis, unless it was
+     intended to call the macro without any arguments.  The brackets
+     around COUNT and ARGUMENT show that these arguments are optional.
+     If COUNT is omitted, the macro behaves as if count were ‘1’,
+     whereas if ARGUMENT is omitted, the macro behaves as if it were the
+     empty string.  A blank argument is not the same as an omitted
+     argument.  For example, ‘example(`a')’, ‘example(`a',`1')’, and
+     ‘example(`a',`1',)’ would behave identically with COUNT set to ‘1’;
+     while ‘example(`a',)’ and ‘example(`a',`')’ would explicitly pass
+     the empty string for COUNT.  The ellipses (‘...’) show that the
+     macro processes additional arguments after ARGUMENT, rather than
+     ignoring them.
+
+   All macro arguments in ‘m4’ are strings, but some are given special
+interpretation, e.g., as numbers, file names, regular expressions, etc.
+The documentation for each macro will state how the parameters are
+interpreted, and what happens if the argument cannot be parsed according
+to the desired interpretation.  Unless specified otherwise, a parameter
+specified to be a number is parsed as a decimal, even if the argument
+has leading zeros; and parsing the empty string as a number results in 0
+rather than an error, although a warning will be issued.
+
+   This document consistently writes and uses “builtin”, without a
+hyphen, as if it were an English word.  This is how the ‘builtin’
+primitive is spelled within ‘m4’.

+
+2 Invoking ‘m4’
+***************
+
+The format of the ‘m4’ command is:
+
+     m4 OPTION... FILE...
+
+   All options begin with ‘-’, or if long option names are used, with
+‘--’.  A long option name need not be written completely, any
+unambiguous prefix is sufficient.  POSIX requires ‘m4’ to recognize
+arguments intermixed with files, even when ‘POSIXLY_CORRECT’ is set in
+the environment.  Most options take effect at startup regardless of
+their position, but some are documented below as taking effect after any
+files that occurred earlier in the command line.  The argument ‘--’ is a
+marker to denote the end of options.
+
+   With short options, options that do not take arguments may be
+combined into a single command line argument with subsequent options,
+options with mandatory arguments may be provided either as a single
+command line argument or as two arguments, and options with optional
+arguments must be provided as a single argument.  In other words, ‘m4
+-QPDfoo -d a -df’ is equivalent to ‘m4 -Q -P -D foo -d -df -- ./a’,
+although the latter form is considered canonical.
+
+   With long options, options with mandatory arguments may be provided
+with an equal sign (‘=’) in a single argument, or as two arguments, and
+options with optional arguments must be provided as a single argument.
+In other words, ‘m4 --def foo --debug a’ is equivalent to ‘m4
+--define=foo --debug= -- ./a’, although the latter form is considered
+canonical (not to mention more robust, in case a future version of ‘m4’
+introduces an option named ‘--default’).
+
+   ‘m4’ understands the following options, grouped by functionality.
+
+* Menu:
+
+* Operation modes::             Command line options for operation modes
+* Preprocessor features::       Command line options for preprocessor features

+&#x1f;
+File: m4.info,  Node: Operation modes,  Next: Preprocessor features,  Up: Invoking m4
+
+2.1 Command line options for operation modes
+============================================
+
+Several options control the overall operation of ‘m4’:
+
+‘--help’
+     Print a help summary on standard output, then immediately exit ‘m4’
+     without reading any input files or performing any other actions.
+
+‘--version’
+     Print the version number of the program on standard output, then
+     immediately exit ‘m4’ without reading any input files or performing
+     any other actions.
+
+‘-E’
+‘--fatal-warnings’
+     Controls the effect of warnings.  If unspecified, then execution
+     continues and exit status is unaffected when a warning is printed.
+     If specified exactly once, warnings become fatal; when one is
+     issued, execution continues, but the exit status will be non-zero.
+     If specified multiple times, then execution halts with non-zero
+     status the first time a warning is issued.  The introduction of
+     behavior levels is new to M4 1.4.9; for behavior consistent with
+     earlier versions, you should specify ‘-E’ twice.
+
+‘-i’
+‘--interactive’
+‘-e’
+     Makes this invocation of ‘m4’ interactive.  This means that all
+     output will be unbuffered, and interrupts will be ignored.  The
+     spelling ‘-e’ exists for compatibility with other ‘m4’
+     implementations, and issues a warning because it may be withdrawn
+     in a future version of GNU M4.
+
+‘-P’
+‘--prefix-builtins’
+     Internally modify _all_ builtin macro names so they all start with
+     the prefix ‘m4_’.  For example, using this option, one should write
+     ‘m4_define’ instead of ‘define’, and ‘m4___file__’ instead of
+     ‘__file__’.  This option has no effect if ‘-R’ is also specified.
+
+‘-Q’
+‘--quiet’
+‘--silent’
+     Suppress warnings, such as missing or superfluous arguments in
+     macro calls, or treating the empty string as zero.
+
+‘--warn-macro-sequence=REGEXP’
+     Issue a warning if the regular expression REGEXP has a non-empty
+     match in any macro definition (either by ‘define’ or ‘pushdef’).
+     Empty matches are ignored; therefore, supplying the empty string as
+     REGEXP disables any warning.  If the optional REGEXP is not
+     supplied, then the default regular expression is
+     ‘\$${^}*}\|0-90-9+$’ (a literal ‘$’ followed by multiple
+     digits or by an open brace), since these sequences will change
+     semantics in the default operation of GNU M4 2.0 (due to a change
+     in how more than 9 arguments in a macro definition will be handled,
+     *note Arguments::).  Providing an alternate regular expression can
+     provide a useful reverse lookup feature of finding where a macro is
+     defined to have a given definition.
+
+‘-W REGEXP’
+‘--word-regexp=REGEXP’
+     Use REGEXP as an alternative syntax for macro names.  This
+     experimental option will not be present in all GNU ‘m4’
+     implementations (*note Changeword::).
+
+&#x1f;
+File: m4.info,  Node: Preprocessor features,  Next: Limits control,  Prev: Operation modes,  Up: Invoking m4
+
+2.2 Command line options for preprocessor features
+==================================================
+
+Several options allow ‘m4’ to behave more like a preprocessor.  Macro
+definitions and deletions can be made on the command line, the search
+path can be altered, and the output file can track where the input came
+from.  These features occur with the following options:
+
+‘-D NAME=VALUE’
+‘--define=NAME=VALUE’
+     This enters NAME into the symbol table.  If ‘=VALUE’ is missing,
+     the value is taken to be the empty string.  The VALUE can be any
+     string, and the macro can be defined to take arguments, just as if
+     it was defined from within the input.  This option may be given
+     more than once; order with respect to file names is significant,
+     and redefining the same NAME loses the previous value.
+
+‘-I DIRECTORY’
+‘--include=DIRECTORY’
+     Make ‘m4’ search DIRECTORY for included files that are not found in
+     the current working directory.  *Note Search Path::, for more
+     details.  This option may be given more than once.
+
+‘-s’
+‘--synclines’
+     Generate synchronization lines, for use by the C preprocessor or
+     other similar tools.  Order is significant with respect to file
+     names.  This option is useful, for example, when ‘m4’ is used as a
+     front end to a compiler.  Source file name and line number
+     information is conveyed by directives of the form ‘#line LINENUM
+     "FILE"’, which are inserted as needed into the middle of the
+     output.  Such directives mean that the following line originated or
+     was expanded from the contents of input file FILE at line LINENUM.
+     The ‘"FILE"’ part is often omitted when the file name did not
+     change from the previous directive.
+
+     Synchronization directives are always given on complete lines by
+     themselves.  When a synchronization discrepancy occurs in the
+     middle of an output line, the associated synchronization directive
+     is delayed until the next newline that does not occur in the middle
+     of a quoted string or comment.
+
+          define(`twoline', `1
+          2')
+          ⇒#line 2 "stdin"
+          ⇒
+          changecom(`/*', `*/')
+          ⇒
+          define(`comment', `/*1
+          2*/')
+          ⇒#line 5
+          ⇒
+          dnl no line
+          hello
+          ⇒#line 7
+          ⇒hello
+          twoline
+          ⇒1
+          ⇒#line 8
+          ⇒2
+          comment
+          ⇒/*1
+          ⇒2*/
+          one comment `two
+          three'
+          ⇒#line 10
+          ⇒one /*1
+          ⇒2*/ two
+          ⇒three
+          goodbye
+          ⇒#line 12
+          ⇒goodbye
+
+‘-U NAME’
+‘--undefine=NAME’
+     This deletes any predefined meaning NAME might have.  Obviously,
+     only predefined macros can be deleted in this way.  This option may
+     be given more than once; undefining a NAME that does not have a
+     definition is silently ignored.  Order is significant with respect
+     to file names.

+File: m4.info,  Node: Limits control,  Next: Frozen state,  Prev: Preprocessor features,  Up: Invoking m4
+
+2.3 Command line options for limits control
+===========================================
+
+There are some limits within ‘m4’ that can be tuned.  For compatibility,
+‘m4’ also accepts some options that control limits in other
+implementations, but which are automatically unbounded (limited only by
+your hardware and operating system constraints) in GNU ‘m4’.
+
+‘-g’
+‘--gnu’
+     Enable all the extensions in this implementation.  In this release
+     of M4, this option is always on by default; it is currently only
+     useful when overriding a prior use of ‘--traditional’.  However,
+     having GNU behavior as default makes it impossible to write a
+     strictly POSIX-compliant client that avoids all incompatible GNU M4
+     extensions, since such a client would have to use the non-POSIX
+     command-line option to force full POSIX behavior.  Thus, a future
+     version of M4 will be changed to implicitly use the option
+     ‘--traditional’ if the environment variable ‘POSIXLY_CORRECT’ is
+     set.  Projects that intentionally use GNU extensions should
+     consider using ‘--gnu’ to state their intentions, so that the
+     project will not mysteriously break if the user upgrades to a newer
+     M4 and has ‘POSIXLY_CORRECT’ set in their environment.
+
+‘-G’
+‘--traditional’
+     Suppress all the extensions made in this implementation, compared
+     to the System V version.  *Note Compatibility::, for a list of
+     these.
+
+‘-H NUM’
+‘--hashsize=NUM’
+     Make the internal hash table for symbol lookup be NUM entries big.
+     For better performance, the number should be prime, but this is not
+     checked.  The default is 65537 entries.  It should not be necessary
+     to increase this value, unless you define an excessive number of
+     macros.
+
+‘-L NUM’
+‘--nesting-limit=NUM’
+     Artificially limit the nesting of macro calls to NUM levels,
+     stopping program execution if this limit is ever exceeded.  When
+     not specified, nesting defaults to unlimited on platforms that can
+     detect stack overflow, and to 1024 levels otherwise.  A value of
+     zero means unlimited; but then heavily nested code could
+     potentially cause a stack overflow.
+
+     The precise effect of this option is more correctly associated with
+     textual nesting than dynamic recursion.  It has been useful when
+     some complex ‘m4’ input was generated by mechanical means, and also
+     in diagnosing recursive algorithms that do not scale well.  Most
+     users never need to change this option from its default.
+
+     This option does _not_ have the ability to break endless rescanning
+     loops, since these do not necessarily consume much memory or stack
+     space.  Through clever usage of rescanning loops, one can request
+     complex, time-consuming computations from ‘m4’ with useful results.
+     Putting limitations in this area would break ‘m4’ power.  There are
+     many pathological cases: ‘define(`a', `a')a’ is only the simplest
+     example (but *note Compatibility::).  Expecting GNU ‘m4’ to detect
+     these would be a little like expecting a compiler system to detect
+     and diagnose endless loops: it is a quite _hard_ problem in
+     general, if not undecidable!
+
+‘-B NUM’
+‘-S NUM’
+‘-T NUM’
+     These options are present for compatibility with System V ‘m4’, but
+     do nothing in this implementation.  They may disappear in future
+     releases, and issue a warning to that effect.
+
+‘-N NUM’
+‘--diversions=NUM’
+     These options are present only for compatibility with previous
+     versions of GNU ‘m4’, and were controlling the number of possible
+     diversions which could be used at the same time.  They do nothing,
+     because there is no fixed limit anymore.  They may disappear in
+     future releases, and issue a warning to that effect.
+

+File: m4.info,  Node: Frozen state,  Next: Debugging options,  Prev: Limits control,  Up: Invoking m4
+
+2.4 Command line options for frozen state
+=========================================
+
+GNU ‘m4’ comes with a feature of freezing internal state (*note Frozen
+files::).  This can be used to speed up ‘m4’ execution when reusing a
+common initialization script.
+
+‘-F FILE’
+‘--freeze-state=FILE’
+     Once execution is finished, write out the frozen state on the
+     specified FILE.  It is conventional, but not required, for FILE to
+     end in ‘.m4f’.
+
+‘-R FILE’
+‘--reload-state=FILE’
+     Before execution starts, recover the internal state from the
+     specified frozen FILE.  The options ‘-D’, ‘-U’, and ‘-t’ take
+     effect after state is reloaded, but before the input files are
+     read.
+
+&#x1f;
+File: m4.info,  Node: Debugging options,  Next: Command line files,  Prev: Frozen state,  Up: Invoking m4
+
+2.5 Command line options for debugging
+======================================
+
+Finally, there are several options for aiding in debugging ‘m4’ scripts.
+
+‘-dFLAGS’
+‘--debug=FLAGS’
+     Set the debug-level according to the flags FLAGS.  The debug-level
+     controls the format and amount of information presented by the
+     debugging functions.  *Note Debug Levels::, for more details on the
+     format and meaning of FLAGS.  If omitted, FLAGS defaults to ‘aeq’.
+
+‘--debugfile=FILE’
+‘-o FILE’
+‘--error-output=FILE’
+     Redirect ‘dumpdef’ output, debug messages, and trace output to the
+     named FILE.  Warnings, error messages, and ‘errprint’ output are
+     still printed to standard error.  If these options are not used, or
+     if FILE is unspecified (only possible for ‘--debugfile’), debug
+     output goes to standard error; if FILE is the empty string, debug
+     output is discarded.  *Note Debug Output::, for more details.  The
+     option ‘--debugfile’ may be given more than once, and order is
+     significant with respect to file names.  The spellings ‘-o’ and
+     ‘--error-output’ are misleading and inconsistent with other GNU
+     tools; for now they are silently accepted as synonyms of
+     ‘--debugfile’ and only recognized once, but in a future version of
+     M4, using them will cause a warning to be issued.
+
+‘-l NUM’
+‘--arglength=NUM’
+     Restrict the size of the output generated by macro tracing to NUM
+     characters per trace line.  If unspecified or zero, output is
+     unlimited.  *Note Debug Levels::, for more details.
+
+‘-t NAME’
+‘--trace=NAME’
+     This enables tracing for the macro NAME, at any point where it is
+     defined.  NAME need not be defined when this option is given.  This
+     option may be given more than once, and order is significant with
+     respect to file names.  *Note Trace::, for more details.
+
+&#x1f;
+File: m4.info,  Node: Command line files,  Prev: Debugging options,  Up: Invoking m4
+
+2.6 Specifying input files on the command line
+==============================================
+
+The remaining arguments on the command line are taken to be input file
+names.  If no names are present, standard input is read.  A file name of
+‘-’ is taken to mean standard input.  It is conventional, but not
+required, for input files to end in ‘.m4’.
+
+   The input files are read in the sequence given.  Standard input can
+be read more than once, so the file name ‘-’ may appear multiple times
+on the command line; this makes a difference when input is from a
+terminal or other special file type.  It is an error if an input file
+ends in the middle of argument collection, a comment, or a quoted
+string.
+
+   The options ‘--define’ (‘-D’), ‘--undefine’ (‘-U’), ‘--synclines’
+(‘-s’), and ‘--trace’ (‘-t’) only take effect after processing input
+from any file names that occur earlier on the command line.  For
+example, assume the file ‘foo’ contains:
+
+     $ cat foo
+     bar
+
+   The text ‘bar’ can then be redefined over multiple uses of ‘foo’:
+
+     $ m4 -Dbar=hello foo -Dbar=world foo
+     ⇒hello
+     ⇒world
+
+   If none of the input files invoked ‘m4exit’ (*note M4exit::), the
+exit status of ‘m4’ will be 0 for success, 1 for general failure (such
+as problems with reading an input file), and 63 for version mismatch
+(*note Using frozen files::).
+
+   If you need to read a file whose name starts with a ‘-’, you can
+specify it as ‘./-file’, or use ‘--’ to mark the end of options.

+
+3 Lexical and syntactic conventions
+***********************************
+
+As ‘m4’ reads its input, it separates it into “tokens”.  A token is
+either a name, a quoted string, or any single character, that is not a
+part of either a name or a string.  Input to ‘m4’ can also contain
+comments.  GNU ‘m4’ does not yet understand multibyte locales; all
+operations are byte-oriented rather than character-oriented (although if
+your locale uses a single byte encoding, such as ISO-8859-1, you will
+not notice a difference).  However, ‘m4’ is eight-bit clean, so you can
+use non-ASCII characters in quoted strings (*note Changequote::),
+comments (*note Changecom::), and macro names (*note Indir::), with the
+exception of the NUL character (the zero byte ‘'\0'’).

+File: m4.info,  Node: Names,  Next: Quoted strings,  Up: Syntax
+
+3.1 Macro names
+===============
+
+A name is any sequence of letters, digits, and the character ‘_’
+(underscore), where the first character is not a digit.  ‘m4’ will use
+the longest such sequence found in the input.  If a name has a macro
+definition, it will be subject to macro expansion (*note Macros::).
+Names are case-sensitive.
+
+   Examples of legal names are: ‘foo’, ‘_tmp’, and ‘name01’.

+&#x1f;
+File: m4.info,  Node: Quoted strings,  Next: Comments,  Prev: Names,  Up: Syntax
+
+3.2 Quoting input to ‘m4’
+=========================
+
+A quoted string is a sequence of characters surrounded by quote strings,
+defaulting to ‘`’ and ‘'’, where the nested begin and end quotes within
+the string are balanced.  The value of a string token is the text, with
+one level of quotes stripped off.  Thus
+
+     `'
+     ⇒
+
+is the empty string, and double-quoting turns into single-quoting.
+
+     ``quoted''
+     ⇒`quoted'
+
+   The quote characters can be changed at any time, using the builtin
+macro ‘changequote’.  *Note Changequote::, for more information.
+
+&#x1f;
+File: m4.info,  Node: Comments,  Next: Other tokens,  Prev: Quoted strings,  Up: Syntax
+
+3.3 Comments in ‘m4’ input
+==========================
+
+Comments in ‘m4’ are normally delimited by the characters ‘#’ and
+newline.  All characters between the comment delimiters are ignored, but
+the entire comment (including the delimiters) is passed through to the
+output—comments are _not_ discarded by ‘m4’.
+
+   Comments cannot be nested, so the first newline after a ‘#’ ends the
+comment.  The commenting effect of the begin-comment string can be
+inhibited by quoting it.
+
+     $ m4
+     `quoted text' # `commented text'
+     ⇒quoted text # `commented text'
+     `quoting inhibits' `#' `comments'
+     ⇒quoting inhibits # comments
+
+   The comment delimiters can be changed to any string at any time,
+using the builtin macro ‘changecom’.  *Note Changecom::, for more
+information.

+3.4 Other kinds of input tokens
+===============================
+
+Any character, that is neither a part of a name, nor of a quoted string,
+nor a comment, is a token by itself.  When not in the context of macro
+expansion, all of these tokens are just copied to output.  However,
+during macro expansion, whitespace characters (space, tab, newline,
+formfeed, carriage return, vertical tab), parentheses (‘(’ and ‘)’),
+comma (‘,’), and dollar (‘$’) have additional roles, explained later.
+
+&#x1f;
+File: m4.info,  Node: Input processing,  Prev: Other tokens,  Up: Syntax
+
+3.5 How ‘m4’ copies input to output
+===================================
+
+As ‘m4’ reads the input token by token, it will copy each token directly
+to the output immediately.
+
+   The exception is when it finds a word with a macro definition.  In
+that case ‘m4’ will calculate the macro’s expansion, possibly reading
+more input to get the arguments.  It then inserts the expansion in front
+of the remaining input.  In other words, the resulting text from a macro
+call will be read and parsed into tokens again.
+
+   ‘m4’ expands a macro as soon as possible.  If it finds a macro call
+when collecting the arguments to another, it will expand the second call
+first.  This process continues until there are no more macro calls to
+expand and all the input has been consumed.
+
+   For a running example, examine how ‘m4’ handles this input:
+
+     format(`Result is %d', eval(`2**15'))
+
+First, ‘m4’ sees that the token ‘format’ is a macro name, so it collects
+the tokens ‘(’, ‘`Result is %d'’, ‘,’, and ‘ ’, before encountering
+another potential macro.  Sure enough, ‘eval’ is a macro name, so the
+nested argument collection picks up ‘(’, ‘`2**15'’, and ‘)’, invoking
+the eval macro with the lone argument of ‘2**15’.  The expansion of
+‘eval(2**15)’ is ‘32768’, which is then rescanned as the five tokens
+‘3’, ‘2’, ‘7’, ‘6’, and ‘8’; and combined with the next ‘)’, the format
+macro now has all its arguments, as if the user had typed:
+
+     format(`Result is %d', 32768)
+
+The format macro expands to ‘Result is 32768’, and we have another round
+of scanning for the tokens ‘Result’, ‘ ’, ‘is’, ‘ ’, ‘3’, ‘2’, ‘7’, ‘6’,
+and ‘8’.  None of these are macros, so the final output is
+
+     ⇒Result is 32768
+
+   As a more complicated example, we will contrast an actual code
+example from the Gnulib project(1), showing both a buggy approach and
+the desired results.  The user desires to output a shell assignment
+statement that takes its argument and turns it into a shell variable by
+converting it to uppercase and prepending a prefix.  The original
+attempt looks like this:
+
+     changequote(,)dnl
+     define(gl_STRING_MODULE_INDICATOR,
+       
+         dnl comment
+         GNULIB_translit($1,a-z,A-Z)=1
+       )dnl
+       gl_STRING_MODULE_INDICATOR(strcase)
+     ⇒  
+     ⇒        GNULIB_strcase=1
+     ⇒  
+
+   Oops – the argument did not get capitalized.  And although the manual
+is not able to easily show it, both lines that appear empty actually
+contain two trailing spaces.  By stepping through the parse, it is easy
+to see what happened.  First, ‘m4’ sees the token ‘changequote’, which
+it recognizes as a macro, followed by ‘(’, ‘’, ‘,’, ‘’, and ‘)’ to
+form the argument list.  The macro expands to the empty string, but
+changes the quoting characters to something more useful for generating
+shell code (unbalanced ‘`’ and ‘'’ appear all the time in shell scripts,
+but unbalanced ‘’ tend to be rare).  Also in the first line, ‘m4’ sees
+the token ‘dnl’, which it recognizes as a builtin macro that consumes
+the rest of the line, resulting in no output for that line.
+
+   The second line starts a macro definition.  ‘m4’ sees the token
+‘define’, which it recognizes as a macro, followed by a ‘(’,
+‘gl_STRING_MODULE_INDICATOR’, and ‘,’.  Because an unquoted comma was
+encountered, the first argument is known to be the expansion of the
+single-quoted string token, or ‘gl_STRING_MODULE_INDICATOR’.  Next, ‘m4’
+sees ‘<NL>’, ‘ ’, and ‘ ’, but this whitespace is discarded as part of
+argument collection.  Then comes a rather lengthy single-quoted string
+token, ‘<NL>    dnl comment<NL>    GNULIB_’.  This is followed by the
+token ‘translit’, which ‘m4’ recognizes as a macro name, so a nested
+macro expansion has started.
+
+   The arguments to the ‘translit’ are found by the tokens ‘(’, ‘$1’,
+‘,’, ‘a-z’, ‘,’, ‘A-Z’, and finally ‘)’.  All three string arguments
+are expanded (or in other words, the quotes are stripped), and since
+neither ‘$’ nor ‘1’ need capitalization, the result of the macro is
+‘$1’.  This expansion is rescanned, resulting in the two literal
+characters ‘$’ and ‘1’.
+
+   Scanning of the outer macro resumes, and picks up with ‘=1<NL>  ’,
+and finally ‘)’.  The collected pieces of expanded text are
+concatenated, with the end result that the macro
+‘gl_STRING_MODULE_INDICATOR’ is now defined to be the sequence
+‘<NL>    dnl comment<NL>    GNULIB_$1=1<NL>  ’.  Once again, ‘dnl’ is
+recognized and avoids a newline in the output.
+
+   The final line is then parsed, beginning with ‘ ’ and ‘ ’ that are
+output literally.  Then ‘gl_STRING_MODULE_INDICATOR’ is recognized as a
+macro name, with an argument list of ‘(’, ‘strcase’, and ‘)’.  Since
+the definition of the macro contains the sequence ‘$1’, that sequence is
+replaced with the argument ‘strcase’ prior to starting the rescan.  The
+rescan sees ‘<NL>’ and four spaces, which are output literally, then
+‘dnl’, which discards the text ‘ comment<NL>’.  Next comes four more
+spaces, also output literally, and the token ‘GNULIB_strcase’, which
+resulted from the earlier parameter substitution.  Since that is not a
+macro name, it is output literally, followed by the literal tokens ‘=’,
+‘1’, ‘<NL>’, and two more spaces.  Finally, the original ‘<NL>’ seen
+after the macro invocation is scanned and output literally.
+
+   Now for a corrected approach.  This rearranges the use of newlines
+and whitespace so that less whitespace is output (which, although
+harmless to shell scripts, can be visually unappealing), and fixes the
+quoting issues so that the capitalization occurs when the macro
+‘gl_STRING_MODULE_INDICATOR’ is invoked, rather then when it is defined.
+It also adds another layer of quoting to the first argument of
+‘translit’, to ensure that the output will be rescanned as a string
+rather than a potential uppercase macro name needing further expansion.
+
+     changequote(,)dnl
+     define(gl_STRING_MODULE_INDICATOR,
+       dnl comment
+       GNULIB_translit($1, a-z, A-Z)=1dnl
+     )dnl
+       gl_STRING_MODULE_INDICATOR(strcase)
+     ⇒    GNULIB_STRCASE=1
+
+   The parsing of the first line is unchanged.  The second line sees the
+name of the macro to define, then sees the discarded ‘<NL>’ and two
+spaces, as before.  But this time, the next token is ‘dnl
+comment<NL>  GNULIB_translit($1, a-z, A-Z)=1dnl<NL>’, which
+includes nested quotes, followed by ‘)’ to end the macro definition and
+‘dnl’ to skip the newline.  No early expansion of ‘translit’ occurs, so
+the entire string becomes the definition of the macro.
+
+   The final line is then parsed, beginning with two spaces that are
+output literally, and an invocation of ‘gl_STRING_MODULE_INDICATOR’ with
+the argument ‘strcase’.  Again, the ‘$1’ in the macro definition is
+substituted prior to rescanning.  Rescanning first encounters ‘dnl’, and
+discards ‘ comment<NL>’.  Then two spaces are output literally.  Next
+comes the token ‘GNULIB_’, but that is not a macro, so it is output
+literally.  The token ‘’ is an empty string, so it does not affect
+output.  Then the token ‘translit’ is encountered.
+
+   This time, the arguments to ‘translit’ are parsed as ‘(’,
+‘strcase’, ‘,’, ‘ ’, ‘a-z’, ‘,’, ‘ ’, ‘A-Z’, and ‘)’.  The two
+spaces are discarded, and the translit results in the desired result
+‘STRCASE’.  This is rescanned, but since it is a string, the quotes
+are stripped and the only output is a literal ‘STRCASE’.  Then the
+scanner sees ‘=’ and ‘1’, which are output literally, followed by ‘dnl’
+which discards the rest of the definition of
+‘gl_STRING_MODULE_INDICATOR’.  The newline at the end of output is the
+literal ‘<NL>’ that appeared after the invocation of the macro.
+
+   The order in which ‘m4’ expands the macros can be further explored
+using the trace facilities of GNU ‘m4’ (*note Trace::).

+4.1 Macro invocation
+====================
+
+Macro invocations has one of the forms
+
+     name
+
+which is a macro invocation without any arguments, or
+
+     name(arg1, arg2, ..., argN)
+
+which is a macro invocation with N arguments.  Macros can have any
+number of arguments.  All arguments are strings, but different macros
+might interpret the arguments in different ways.
+
+   The opening parenthesis _must_ follow the NAME directly, with no
+spaces in between.  If it does not, the macro is called with no
+arguments at all.
+
+   For a macro call to have no arguments, the parentheses _must_ be left
+out.  The macro call
+
+     name()
+
+is a macro call with one argument, which is the empty string, not a call
+with no arguments.
+
+&#x1f;
+File: m4.info,  Node: Inhibiting Invocation,  Next: Macro Arguments,  Prev: Invocation,  Up: Macros
+
+4.2 Preventing macro invocation
+===============================
+
+An innovation of the ‘m4’ language, compared to some of its predecessors
+(like Strachey’s ‘GPM’, for example), is the ability to recognize macro
+calls without resorting to any special, prefixed invocation character.
+While generally useful, this feature might sometimes be the source of
+spurious, unwanted macro calls.  So, GNU ‘m4’ offers several mechanisms
+or techniques for inhibiting the recognition of names as macro calls.
+
+   First of all, many builtin macros cannot meaningfully be called
+without arguments.  As a GNU extension, for any of these macros,
+whenever an opening parenthesis does not immediately follow their name,
+the builtin macro call is not triggered.  This solves the most usual
+cases, like for ‘include’ or ‘eval’.  Later in this document, the
+sentence “This macro is recognized only with parameters” refers to this
+specific provision of GNU M4, also known as a blind builtin macro.  For
+the builtins defined by POSIX that bear this disclaimer, POSIX
+specifically states that invoking those builtins without arguments is
+unspecified, because many other implementations simply invoke the
+builtin as though it were given one empty argument instead.
+
+     $ m4
+     eval
+     ⇒eval
+     eval(`1')
+     ⇒1
+
+   There is also a command line option (‘--prefix-builtins’, or ‘-P’,
+*note Invoking m4: Operation modes.) that renames all builtin macros
+with a prefix of ‘m4_’ at startup.  The option has no effect whatsoever
+on user defined macros.  For example, with this option, one has to write
+‘m4_dnl’ and even ‘m4_m4exit’.  It also has no effect on whether a macro
+requires parameters.
+
+     $ m4 -P
+     eval
+     ⇒eval
+     eval(`1')
+     ⇒eval(1)
+     m4_eval
+     ⇒m4_eval
+     m4_eval(`1')
+     ⇒1
+
+   Another alternative is to redefine problematic macros to a name less
+likely to cause conflicts, using *note Definitions::.
+
+   If your version of GNU ‘m4’ has the ‘changeword’ feature compiled in,
+it offers far more flexibility in specifying the syntax of macro names,
+both builtin or user-defined.  *Note Changeword::, for more information
+on this experimental feature.
+
+   Of course, the simplest way to prevent a name from being interpreted
+as a call to an existing macro is to quote it.  The remainder of this
+section studies a little more deeply how quoting affects macro
+invocation, and how quoting can be used to inhibit macro invocation.
+
+   Even if quoting is usually done over the whole macro name, it can
+also be done over only a few characters of this name (provided, of
+course, that the unquoted portions are not also a macro).  It is also
+possible to quote the empty string, but this works only _inside_ the
+name.  For example:
+
+     `divert'
+     ⇒divert
+     `d'ivert
+     ⇒divert
+     di`ver't
+     ⇒divert
+     div`'ert
+     ⇒divert
+
+all yield the string ‘divert’.  While in both:
+
+     `'divert
+     ⇒
+     divert`'
+     ⇒
+
+the ‘divert’ builtin macro will be called, which expands to the empty
+string.
+
+   The output of macro evaluations is always rescanned.  In the
+following example, the input ‘x`'y’ yields the string ‘bCD’, exactly as
+if ‘m4’ has been given ‘substr(ab`'cde, `1', `3')’ as input:
+
+     define(`cde', `CDE')
+     ⇒
+     define(`x', `substr(ab')
+     ⇒
+     define(`y', `cde, `1', `3')')
+     ⇒
+     x`'y
+     ⇒bCD
+
+   Unquoted strings on either side of a quoted string are subject to
+being recognized as macro names.  In the following example, quoting the
+empty string allows for the second ‘macro’ to be recognized as such:
+
+     define(`macro', `m')
+     ⇒
+     macro(`m')macro
+     ⇒mmacro
+     macro(`m')`'macro
+     ⇒mm
+
+   Quoting may prevent recognizing as a macro name the concatenation of
+a macro expansion with the surrounding characters.  In this example:
+
+     define(`macro', `di$1')
+     ⇒
+     macro(`v')`ert'
+     ⇒divert
+     macro(`v')ert
+     ⇒
+
+the input will produce the string ‘divert’.  When the quotes were
+removed, the ‘divert’ builtin was called instead.
+

+
+4.3 Macro arguments
+===================
+
+When a name is seen, and it has a macro definition, it will be expanded
+as a macro.
+
+   If the name is followed by an opening parenthesis, the arguments will
+be collected before the macro is called.  If too few arguments are
+supplied, the missing arguments are taken to be the empty string.
+However, some builtins are documented to behave differently for a
+missing optional argument than for an explicit empty string.  If there
+are too many arguments, the excess arguments are ignored.  Unquoted
+leading whitespace is stripped off all arguments, but whitespace
+generated by a macro expansion or occurring after a macro that expanded
+to an empty string remains intact.  Whitespace includes space, tab,
+newline, carriage return, vertical tab, and formfeed.
+
+     define(`macro', `$1')
+     ⇒
+     macro( unquoted leading space lost)
+     ⇒unquoted leading space lost
+     macro(` quoted leading space kept')
+     ⇒ quoted leading space kept
+     macro(
+      divert `unquoted space kept after expansion')
+     ⇒ unquoted space kept after expansion
+     macro(macro(`
+     ')`whitespace from expansion kept')
+     ⇒
+     ⇒whitespace from expansion kept
+     macro(`unquoted trailing whitespace kept'
+     )
+     ⇒unquoted trailing whitespace kept
+     ⇒
+
+   Normally ‘m4’ will issue warnings if a builtin macro is called with
+an inappropriate number of arguments, but it can be suppressed with the
+‘--quiet’ command line option (or ‘--silent’, or ‘-Q’, *note Invoking
+m4: Operation modes.).  For user defined macros, there is no check of
+the number of arguments given.
+
+     $ m4
+     index(`abc')
+     error→m4:stdin:1: Warning: too few arguments to builtin `index'
+     ⇒0
+     index(`abc',)
+     ⇒0
+     index(`abc', `b', `ignored')
+     error→m4:stdin:3: Warning: excess arguments to builtin `index' ignored
+     ⇒1
+
+     $ m4 -Q
+     index(`abc')
+     ⇒0
+     index(`abc',)
+     ⇒0
+     index(`abc', `b', `ignored')
+     ⇒1
+
+   Macros are expanded normally during argument collection, and whatever
+commas, quotes and parentheses that might show up in the resulting
+expanded text will serve to define the arguments as well.  Thus, if FOO
+expands to ‘, b, c’, the macro call
+
+     bar(a foo, d)
+
+is a macro call with four arguments, which are ‘a ’, ‘b’, ‘c’ and ‘d’.
+To understand why the first argument contains whitespace, remember that
+unquoted leading whitespace is never part of an argument, but trailing
+whitespace always is.
+
+   It is possible for a macro’s definition to change during argument
+collection, in which case the expansion uses the definition that was in
+effect at the time the opening ‘(’ was seen.
+
+     define(`f', `1')
+     ⇒
+     f(define(`f', `2'))
+     ⇒1
+     f
+     ⇒2
+
+   It is an error if the end of file occurs while collecting arguments.
+
+     hello world
+     ⇒hello world
+     define(
+     ^D
+     error→m4:stdin:2: ERROR: end of file in argument list
+
+&#x1f;
+File: m4.info,  Node: Quoting Arguments,  Next: Macro expansion,  Prev: Macro Arguments,  Up: Macros
+
+4.4 On Quoting Arguments to macros
+==================================
+
+Each argument has unquoted leading whitespace removed.  Within each
+argument, all unquoted parentheses must match.  For example, if FOO is a
+macro,
+
+     foo(() (`(') `(')
+
+is a macro call, with one argument, whose value is ‘() (() (’.  Commas
+separate arguments, except when they occur inside quotes, comments, or
+unquoted parentheses.  *Note Pseudo Arguments::, for examples.
+
+   It is common practice to quote all arguments to macros, unless you
+are sure you want the arguments expanded.  Thus, in the above example
+with the parentheses, the ‘right’ way to do it is like this:
+
+     foo(`() (() (')
+
+   It is, however, in certain cases necessary (because nested expansion
+must occur to create the arguments for the outer macro) or convenient
+(because it uses fewer characters) to leave out quotes for some
+arguments, and there is nothing wrong in doing it.  It just makes life a
+bit harder, if you are not careful to follow a consistent quoting style.
+For consistency, this manual follows the rule of thumb that each layer
+of parentheses introduces another layer of single quoting, except when
+showing the consequences of quoting rules.  This is done even when the
+quoted string cannot be a macro, such as with integers when you have not
+changed the syntax via ‘changeword’ (*note Changeword::).
+
+   The quoting rule of thumb of one level of quoting per parentheses has
+a nice property: when a macro name appears inside parentheses, you can
+determine when it will be expanded.  If it is not quoted, it will be
+expanded prior to the outer macro, so that its expansion becomes the
+argument.  If it is single-quoted, it will be expanded after the outer
+macro.  And if it is double-quoted, it will be used as literal text
+instead of a macro name.
+
+     define(`active', `ACT, IVE')
+     ⇒
+     define(`show', `$1 $1')
+     ⇒
+     show(active)
+     ⇒ACT ACT
+     show(`active')
+     ⇒ACT, IVE ACT, IVE
+     show(``active'')
+     ⇒active active
+

+File: m4.info,  Node: Macro expansion,  Prev: Quoting Arguments,  Up: Macros
+
+4.5 Macro expansion
+===================
+
+When the arguments, if any, to a macro call have been collected, the
+macro is expanded, and the expansion text is pushed back onto the input
+(unquoted), and reread.  The expansion text from one macro call might
+therefore result in more macros being called, if the calls are included,
+completely or partially, in the first macro calls’ expansion.
+
+   Taking a very simple example, if FOO expands to ‘bar’, and BAR
+expands to ‘Hello’, the input
+
+     $ m4 -Dbar=Hello -Dfoo=bar
+     foo
+     ⇒Hello
+
+will expand first to ‘bar’, and when this is reread and expanded, into
+‘Hello’.

+
+&#x1f;
+File: m4.info,  Node: Define,  Next: Arguments,  Up: Definitions
+
+5.1 Defining a macro
+====================
+
+The normal way to define or redefine macros is to use the builtin
+‘define’:
+
+ -- Builtin: define (NAME, EXPANSION)
+     Defines NAME to expand to EXPANSION.  If EXPANSION is not given, it
+     is taken to be empty.
+
+     The expansion of ‘define’ is void.  The macro ‘define’ is
+     recognized only with parameters.
+
+   The following example defines the macro FOO to expand to the text
+‘Hello World.’.
+
+     define(`foo', `Hello world.')
+     ⇒
+     foo
+     ⇒Hello world.
+
+   The empty line in the output is there because the newline is not a
+part of the macro definition, and it is consequently copied to the
+output.  This can be avoided by use of the macro ‘dnl’.  *Note Dnl::,
+for details.
+
+   The first argument to ‘define’ should be quoted; otherwise, if the
+macro is already defined, you will be defining a different macro.  This
+example shows the problems with underquoting, since we did not want to
+redefine ‘one’:
+
+     define(foo, one)
+     ⇒
+     define(foo, two)
+     ⇒
+     one
+     ⇒two
+
+   GNU ‘m4’ normally replaces only the _topmost_ definition of a macro
+if it has several definitions from ‘pushdef’ (*note Pushdef::).  Some
+other implementations of ‘m4’ replace all definitions of a macro with
+‘define’.  *Note Incompatibilities::, for more details.
+
+   As a GNU extension, the first argument to ‘define’ does not have to
+be a simple word.  It can be any text string, even the empty string.  A
+macro with a non-standard name cannot be invoked in the normal way, as
+the name is not recognized.  It can only be referenced by the builtins
+‘indir’ (*note Indir::) and ‘defn’ (*note Defn::).
+
+   Arrays and associative arrays can be simulated by using non-standard
+macro names.
+
+ -- Composite: array (INDEX)

+5.2 Arguments to macros
+=======================
+
+Macros can have arguments.  The Nth argument is denoted by ‘$n’ in the
+expansion text, and is replaced by the Nth actual argument, when the
+macro is expanded.  Replacement of arguments happens before rescanning,
+regardless of how many nesting levels of quoting appear in the
+expansion.  Here is an example of a macro with two arguments.
+
+ -- Composite: exch (ARG1, ARG2)
+     Expands to ARG2 followed by ARG1, effectively exchanging their
+     order.
+
+     define(`exch', `$2, $1')
+     ⇒
+     exch(`arg1', `arg2')
+     ⇒arg2, arg1
+
+   This can be used, for example, if you like the arguments to ‘define’
+to be reversed.
+
+     define(`exch', `$2, $1')
+     ⇒
+     define(exch(``expansion text'', ``macro''))
+     ⇒
+     macro
+     ⇒expansion text
+
+   *Note Quoting Arguments::, for an explanation of the double quotes.
+(You should try and improve this example so that clients of ‘exch’ do
+not have to double quote; or *note Answers: Improved exch.).
+
+   As a special case, the zeroth argument, ‘$0’, is always the name of
+the macro being expanded.
+
+     define(`test', ``Macro name: $0'')
+     ⇒
+     test
+     ⇒Macro name: test
+
+   If you want quoted text to appear as part of the expansion text,
+remember that quotes can be nested in quoted strings.  Thus, in
+
+     define(`foo', `This is macro `foo'.')
+     ⇒
+     foo
+     ⇒This is macro foo.
+
+The ‘foo’ in the expansion text is _not_ expanded, since it is a quoted
+string, and not a name.
+
+   GNU ‘m4’ allows the number following the ‘$’ to consist of one or
+more digits, allowing macros to have any number of arguments.  The
+extension of accepting multiple digits is incompatible with POSIX, and
+is different than traditional implementations of ‘m4’, which only
+recognize one digit.  Therefore, future versions of GNU M4 will phase
+out this feature.  To portably access beyond the ninth argument, you can
+use the ‘argn’ macro documented later (*note Shift::).
+
+   POSIX also states that ‘$’ followed immediately by ‘{’ in a macro
+definition is implementation-defined.  This version of M4 passes the
+literal characters ‘${’ through unchanged, but M4 2.0 will implement an
+optional feature similar to ‘sh’, where ‘${11}’ expands to the eleventh
+argument, to replace the current recognition of ‘$11’.  Meanwhile, if
+you want to guarantee that you will get a literal ‘${’ in output when
+expanding a macro, even when you upgrade to M4 2.0, you can use nested
+quoting to your advantage:
+
+     define(`foo', `single quoted $`'{1} output')
+     ⇒
+     define(`bar', ``double quoted $'`{2} output'')
+     ⇒
+     foo(`a', `b')
+     ⇒single quoted ${1} output
+     bar(`a', `b')
+     ⇒double quoted ${2} output
+
+   To help you detect places in your M4 input files that might change in
+behavior due to the changed behavior of M4 2.0, you can use the
+‘--warn-macro-sequence’ command-line option (*note Invoking m4:
+Operation modes.) with the default regular expression.  This will add a
+warning any time a macro definition includes ‘$’ followed by multiple
+digits, or by ‘{’.  The warning is not enabled by default, because it
+triggers a number of warnings in Autoconf 2.61 (and Autoconf uses ‘-E’
+to treat warnings as errors), and because it will still be possible to
+restore older behavior in M4 2.0.
+
+     $ m4 --warn-macro-sequence
+     define(`foo', `$001 ${1} $1')
+     error→m4:stdin:1: Warning: definition of `foo' contains sequence `$001'
+     error→m4:stdin:1: Warning: definition of `foo' contains sequence `${1}'
+     ⇒
+     foo(`bar')
+     ⇒bar ${1} bar
+

+
+5.3 Special arguments to macros
+===============================
+
+There is a special notation for the number of actual arguments supplied,
+and for all the actual arguments.
+
+   The number of actual arguments in a macro call is denoted by ‘$#’ in
+the expansion text.
+
+ -- Composite: nargs (...)
+     Expands to a count of the number of arguments supplied.
+
+     define(`nargs', `$#')
+     ⇒
+     nargs
+     ⇒0
+     nargs()
+     ⇒1
+     nargs(`arg1', `arg2', `arg3')
+     ⇒3
+     nargs(`commas can be quoted, like this')
+     ⇒1
+     nargs(arg1#inside comments, commas do not separate arguments
+     still arg1)
+     ⇒1
+     nargs((unquoted parentheses, like this, group arguments))
+     ⇒1
+
+   Remember that ‘#’ defaults to the comment character; if you forget
+quotes to inhibit the comment behavior, your macro definition may not
+end where you expected.
+
+     dnl Attempt to define a macro to just `$#'
+     define(underquoted, $#)
+     oops)
+     ⇒
+     underquoted
+     ⇒0)
+     ⇒oops
+
+   The notation ‘$*’ can be used in the expansion text to denote all the
+actual arguments, unquoted, with commas in between.  For example
+
+     define(`echo', `$*')
+     ⇒
+     echo(arg1,    arg2, arg3 , arg4)
+     ⇒arg1,arg2,arg3 ,arg4
+
+   Often each argument should be quoted, and the notation ‘$@’ handles
+that.  It is just like ‘$*’, except that it quotes each argument.  A
+simple example of that is:
+
+     define(`echo', `$@')
+     ⇒
+     echo(arg1,    arg2, arg3 , arg4)
+     ⇒arg1,arg2,arg3 ,arg4
+
+   Where did the quotes go?  Of course, they were eaten, when the
+expanded text were reread by ‘m4’.  To show the difference, try
+
+     define(`echo1', `$*')
+     ⇒
+     define(`echo2', `$@')
+     ⇒
+     define(`foo', `This is macro `foo'.')
+     ⇒
+     echo1(foo)
+     ⇒This is macro This is macro foo..
+     echo1(`foo')
+     ⇒This is macro foo.
+     echo2(foo)
+     ⇒This is macro foo.
+     echo2(`foo')
+     ⇒foo
+
+*Note Trace::, if you do not understand this.  As another example of the
+difference, remember that comments encountered in arguments are passed
+untouched to the macro, and that quoting disables comments.
+
+     define(`echo1', `$*')
+     ⇒
+     define(`echo2', `$@')
+     ⇒
+     define(`foo', `bar')
+     ⇒
+     echo1(#foo'foo
+     foo)
+     ⇒#foo'foo
+     ⇒bar
+     echo2(#foo'foo
+     foo)
+     ⇒#foobar
+     ⇒bar'
+
+   A ‘$’ sign in the expansion text, that is not followed by anything
+‘m4’ understands, is simply copied to the macro expansion, as any other
+text is.
+
+     define(`foo', `$$$ hello $$$')
+     ⇒
+     foo
+     ⇒$$$ hello $$$
+
+   If you want a macro to expand to something like ‘$12’, the judicious
+use of nested quoting can put a safe character between the ‘$’ and the
+next character, relying on the rescanning to remove the nested quote.
+This will prevent ‘m4’ from interpreting the ‘$’ sign as a reference to
+an argument.
+
+     define(`foo', `no nested quote: $1')
+     ⇒
+     foo(`arg')
+     ⇒no nested quote: arg
+     define(`foo', `nested quote around $: `$'1')
+     ⇒
+     foo(`arg')
+     ⇒nested quote around $: $1
+     define(`foo', `nested empty quote after $: $`'1')
+     ⇒
+     foo(`arg')
+     ⇒nested empty quote after $: $1
+     define(`foo', `nested quote around next character: $`1'')
+     ⇒
+     foo(`arg')
+     ⇒nested quote around next character: $1
+     define(`foo', `nested quote around both: `$1'')
+     ⇒
+     foo(`arg')
+     ⇒nested quote around both: arg

+
+5.4 Deleting a macro
+====================
+
+A macro definition can be removed with ‘undefine’:
+
+ -- Builtin: undefine (NAME...)
+     For each argument, remove the macro NAME.  The macro names must
+     necessarily be quoted, since they will be expanded otherwise.
+
+     The expansion of ‘undefine’ is void.  The macro ‘undefine’ is
+     recognized only with parameters.
+
+     foo bar blah
+     ⇒foo bar blah
+     define(`foo', `some')define(`bar', `other')define(`blah', `text')
+     ⇒
+     foo bar blah
+     ⇒some other text
+     undefine(`foo')
+     ⇒
+     foo bar blah
+     ⇒foo other text
+     undefine(`bar', `blah')
+     ⇒
+     foo bar blah
+     ⇒foo bar blah
+
+   Undefining a macro inside that macro’s expansion is safe; the macro
+still expands to the definition that was in effect at the ‘(’.
+
+     define(`f', ``$0':$1')
+     ⇒
+     f(f(f(undefine(`f')`hello world')))
+     ⇒f:f:f:hello world
+     f(`bye')
+     ⇒f(bye)
+
+   It is not an error for NAME to have no macro definition.  In that
+case, ‘undefine’ does nothing.
+

+
+5.5 Renaming macros
+===================
+
+It is possible to rename an already defined macro.  To do this, you need
+the builtin ‘defn’:
+
+ -- Builtin: defn (NAME...)
+     Expands to the _quoted definition_ of each NAME.  If an argument is
+     not a defined macro, the expansion for that argument is empty.
+
+     If NAME is a user-defined macro, the quoted definition is simply
+     the quoted expansion text.  If, instead, there is only one NAME and
+     it is a builtin, the expansion is a special token, which points to
+     the builtin’s internal definition.  This token is only meaningful
+     as the second argument to ‘define’ (and ‘pushdef’), and is silently
+     converted to an empty string in most other contexts.  Combining a
+     builtin with anything else is not supported; a warning is issued
+     and the builtin is omitted from the final expansion.
+
+     The macro ‘defn’ is recognized only with parameters.
+
+   Its normal use is best understood through an example, which shows how
+to rename ‘undefine’ to ‘zap’:
+
+     define(`zap', defn(`undefine'))
+     ⇒
+     zap(`undefine')
+     ⇒
+     undefine(`zap')
+     ⇒undefine(zap)
+
+   In this way, ‘defn’ can be used to copy macro definitions, and also
+definitions of builtin macros.  Even if the original macro is removed,
+the other name can still be used to access the definition.
+
+   The fact that macro definitions can be transferred also explains why
+you should use ‘$0’, rather than retyping a macro’s name in its
+definition:
+
+     define(`foo', `This is `$0'')
+     ⇒
+     define(`bar', defn(`foo'))
+     ⇒
+     bar
+     ⇒This is bar
+
+   Macros used as string variables should be referred through ‘defn’, to
+avoid unwanted expansion of the text:
+
+     define(`string', `The macro dnl is very useful
+     ')
+     ⇒
+     string
+     ⇒The macro 
+     defn(`string')
+     ⇒The macro dnl is very useful
+     ⇒
+
+   However, it is important to remember that ‘m4’ rescanning is purely
+textual.  If an unbalanced end-quote string occurs in a macro
+definition, the rescan will see that embedded quote as the termination
+of the quoted string, and the remainder of the macro’s definition will
+be rescanned unquoted.  Thus it is a good idea to avoid unbalanced
+end-quotes in macro definitions or arguments to macros.
+
+     define(`foo', a'a)
+     ⇒
+     define(`a', `A')
+     ⇒
+     define(`echo', `$@')
+     ⇒
+     foo
+     ⇒A'A
+     defn(`foo')
+     ⇒aA'
+     echo(foo)
+     ⇒AA'
+
+   On the other hand, it is possible to exploit the fact that ‘defn’ can
+concatenate multiple macros prior to the rescanning phase, in order to
+join the definitions of macros that, in isolation, have unbalanced
+quotes.  This is particularly useful when one has used several macros to
+accumulate text that M4 should rescan as a whole.  In the example below,
+note how the use of ‘defn’ on ‘l’ in isolation opens a string, which is
+not closed until the next line; but used on ‘l’ and ‘r’ together results
+in nested quoting.
+
+     define(`l', `<>')define(`r', `<>')
+     ⇒
+     changequote(`', `')
+     ⇒
+     defn(l)defn(r)
+     )
+     ⇒<>defn(r)
+     ⇒)
+     defn(l, r)
+     ⇒<><>
+
+   Using ‘defn’ to generate special tokens for builtin macros outside of
+expected contexts can sometimes trigger warnings.  But most of the time,
+such tokens are silently converted to the empty string.
+
+     $ m4 -d
+     defn(`defn')
+     ⇒
+     define(defn(`divnum'), `cannot redefine a builtin token')
+     error→m4:stdin:2: Warning: define: invalid macro name ignored
+     ⇒
+     divnum
+     ⇒0
+     len(defn(`divnum'))
+     ⇒0
+
+   Also note that ‘defn’ with multiple arguments can only join text
+macros, not builtins, although a future version of GNU M4 may lift this
+restriction.
+
+     $ m4 -d
+     define(`a', `A')define(`AA', `b')
+     ⇒
+     traceon(`defn', `define')
+     ⇒
+     defn(`a', `divnum', `a')
+     error→m4:stdin:3: Warning: cannot concatenate builtin `divnum'
+     error→m4trace: -1- defn(`a', `divnum', `a') -> ``A'`A''
+     ⇒AA

+
+5.6 Temporarily redefining macros
+=================================
+
+It is possible to redefine a macro temporarily, reverting to the
+previous definition at a later time.  This is done with the builtins
+‘pushdef’ and ‘popdef’:
+
+ -- Builtin: pushdef (NAME, EXPANSION)
+ -- Builtin: popdef (NAME...)
+     Analogous to ‘define’ and ‘undefine’.
+
+     These macros work in a stack-like fashion.  A macro is temporarily
+     redefined with ‘pushdef’, which replaces an existing definition of
+     NAME, while saving the previous definition, before the new one is
+     installed.  If there is no previous definition, ‘pushdef’ behaves
+     exactly like ‘define’.
+
+     If a macro has several definitions (of which only one is
+     accessible), the topmost definition can be removed with ‘popdef’.
+     If there is no previous definition, ‘popdef’ behaves like
+     ‘undefine’.
+
+     The expansion of both ‘pushdef’ and ‘popdef’ is void.  The macros
+     ‘pushdef’ and ‘popdef’ are recognized only with parameters.
+
+     define(`foo', `Expansion one.')
+     ⇒
+     foo
+     ⇒Expansion one.
+     pushdef(`foo', `Expansion two.')
+     ⇒
+     foo
+     ⇒Expansion two.
+     pushdef(`foo', `Expansion three.')
+     ⇒
+     pushdef(`foo', `Expansion four.')
+     ⇒
+     popdef(`foo')
+     ⇒
+     foo
+     ⇒Expansion three.
+     popdef(`foo', `foo')
+     ⇒
+     foo
+     ⇒Expansion one.
+     popdef(`foo')
+     ⇒
+     foo
+     ⇒foo
+
+   If a macro with several definitions is redefined with ‘define’, the
+topmost definition is _replaced_ with the new definition.  If it is
+removed with ‘undefine’, _all_ the definitions are removed, and not only
+the topmost one.  However, POSIX allows other implementations that treat
+‘define’ as replacing an entire stack of definitions with a single new
+definition, so to be portable to other implementations, it may be worth
+explicitly using ‘popdef’ and ‘pushdef’ rather than relying on the GNU
+behavior of ‘define’.
+
+     define(`foo', `Expansion one.')
+     ⇒
+     foo
+     ⇒Expansion one.
+     pushdef(`foo', `Expansion two.')
+     ⇒
+     foo
+     ⇒Expansion two.
+     define(`foo', `Second expansion two.')
+     ⇒
+     foo
+     ⇒Second expansion two.
+     undefine(`foo')
+     ⇒
+     foo
+     ⇒foo
+
+   Local variables within macros are made with ‘pushdef’ and ‘popdef’.
+At the start of the macro a new definition is pushed, within the macro
+it is manipulated and at the end it is popped, revealing the former
+definition.
+
+   It is possible to temporarily redefine a builtin with ‘pushdef’ and
+‘defn’.

+
+5.7 Indirect call of macros
+===========================
+
+Any macro can be called indirectly with ‘indir’:
+
+ -- Builtin: indir (NAME, ARGS...)
+     Results in a call to the macro NAME, which is passed the rest of
+     the arguments ARGS.  If NAME is not defined, an error message is
+     printed, and the expansion is void.
+
+     The macro ‘indir’ is recognized only with parameters.
+
+   This can be used to call macros with computed or “invalid” names
+(‘define’ allows such names to be defined):
+
+     define(`$$internal$macro', `Internal macro (name `$0')')
+     ⇒
+     $$internal$macro
+     ⇒$$internal$macro
+     indir(`$$internal$macro')
+     ⇒Internal macro (name $$internal$macro)
+
+   The point is, here, that larger macro packages can have private
+macros defined, that will not be called by accident.  They can _only_ be
+called through the builtin ‘indir’.
+
+   One other point to observe is that argument collection occurs before
+‘indir’ invokes NAME, so if argument collection changes the value of
+NAME, that will be reflected in the final expansion.  This is different
+than the behavior when invoking macros directly, where the definition
+that was in effect before argument collection is used.
+
+     $ m4 -d
+     define(`f', `1')
+     ⇒
+     f(define(`f', `2'))

+     error→m4:stdin:4: undefined macro `f'
+     ⇒
+
+   When handed the result of ‘defn’ (*note Defn::) as one of its
+arguments, ‘indir’ defers to the invoked NAME for whether a token
+representing a builtin is recognized or flattened to the empty string.

+5.8 Indirect call of builtins
+=============================
+
+Builtin macros can be called indirectly with ‘builtin’:
+
+ -- Builtin: builtin (NAME, ARGS...)
+     Results in a call to the builtin NAME, which is passed the rest of
+     the arguments ARGS.  If NAME does not name a builtin, an error
+     message is printed, and the expansion is void.
+
+     The macro ‘builtin’ is recognized only with parameters.
+
+   This can be used even if NAME has been given another definition that
+has covered the original, or been undefined so that no macro maps to the
+builtin.
+
+     pushdef(`define', `hidden')
+     ⇒
+     undefine(`undefine')
+     ⇒
+     define(`foo', `bar')
+     ⇒hidden
+     foo
+     ⇒foo
+     builtin(`define', `foo', defn(`divnum'))
+     ⇒
+     foo
+     ⇒0
+     builtin(`define', `foo', `BAR')

+     foo
+     ⇒BAR
+     builtin(`undefine', `foo')
+     ⇒
+     foo
+     ⇒foo
+
+   The NAME argument only matches the original name of the builtin, even
+when the ‘--prefix-builtins’ option (or ‘-P’, *note Invoking m4:
+Operation modes.) is in effect.  This is different from ‘indir’, which
+only tracks current macro names.
+
+     $ m4 -P

+     m4_indir(`m4_divnum')
+     ⇒0
+
+   Note that ‘indir’ and ‘builtin’ can be used to invoke builtins
+without arguments, even when they normally require parameters to be
+recognized; but it will provoke a warning, and result in a void
+expansion.

+6 Conditionals, loops, and recursion
+************************************
+
+Macros, expanding to plain text, perhaps with arguments, are not quite
+enough.  We would like to have macros expand to different things, based
+on decisions taken at run-time.  For that, we need some kind of
+conditionals.  Also, we would like to have some kind of loop construct,
+so we could do something a number of times, or while some condition is
+true.

+
+6.1 Testing if a macro is defined
+=================================
+
+There are two different builtin conditionals in ‘m4’.  The first is
+‘ifdef’:
+
+ -- Builtin: ifdef (NAME, STRING-1, STRING-2)
+     If NAME is defined as a macro, ‘ifdef’ expands to STRING-1,
+     otherwise to STRING-2.  If STRING-2 is omitted, it is taken to be
+     the empty string (according to the normal rules).
+
+     The macro ‘ifdef’ is recognized only with parameters.
+
+     ifdef(`foo', ``foo' is defined', ``foo' is not defined')
+     ⇒foo is not defined
+     define(`foo', `')
+     ⇒
+     ifdef(`foo', ``foo' is defined', ``foo' is not defined')
+     ⇒foo is defined
+     ifdef(`no_such_macro', `yes', `no', `extra argument')
+     error→m4:stdin:4: Warning: excess arguments to builtin `ifdef' ignored
+     ⇒no
+
+&#x1f;
+File: m4.info,  Node: Ifelse,  Next: Shift,  Prev: Ifdef,  Up: Conditionals
+
+6.2 If-else construct, or multibranch
+=====================================
+
+The other conditional, ‘ifelse’, is much more powerful.  It can be used
+as a way to introduce a long comment, as an if-else construct, or as a
+multibranch, depending on the number of arguments supplied:
+
+ -- Builtin: ifelse (COMMENT)
+ -- Builtin: ifelse (STRING-1, STRING-2, EQUAL, NOT-EQUAL)
+ -- Builtin: ifelse (STRING-1, STRING-2, EQUAL-1, STRING-3, STRING-4,
+          EQUAL-2, ..., NOT-EQUAL)
+     Used with only one argument, the ‘ifelse’ simply discards it and
+     produces no output.
+
+     If called with three or four arguments, ‘ifelse’ expands into
+     EQUAL, if STRING-1 and STRING-2 are equal (character for
+     character), otherwise it expands to NOT-EQUAL.  A final fifth
+     argument is ignored, after triggering a warning.
+
+     If called with six or more arguments, and STRING-1 and STRING-2 are
+     equal, ‘ifelse’ expands into EQUAL-1, otherwise the first three
+     arguments are discarded and the processing starts again.
+
+     The macro ‘ifelse’ is recognized only with parameters.
+
+   Using only one argument is a common ‘m4’ idiom for introducing a
+block comment, as an alternative to repeatedly using ‘dnl’.  This
+special usage is recognized by GNU ‘m4’, so that in this case, the
+warning about missing arguments is never triggered.
+
+     ifelse(`some comments')
+     ⇒
+     ifelse(`foo', `bar')
+     error→m4:stdin:2: Warning: too few arguments to builtin `ifelse'
+     ⇒
+
+   Using three or four arguments provides decision points.
+
+     ifelse(`foo', `bar', `true')
+     ⇒
+     ifelse(`foo', `foo', `true')
+     ⇒true
+     define(`foo', `bar')
+     ⇒
+     ifelse(foo, `bar', `true', `false')
+     ⇒true
+     ifelse(foo, `foo', `true', `false')
+     ⇒false
+
+   Notice how the first argument was used unquoted; it is common to
+compare the expansion of a macro with a string.  With this macro, you
+can now reproduce the behavior of blind builtins, where the macro is
+recognized only with arguments.
+
+     define(`foo', `ifelse(`$#', `0', ``$0'', `arguments:$#')')
+     ⇒
+     foo
+     ⇒foo
+     foo()
+     ⇒arguments:1
+     foo(`a', `b', `c')
+     ⇒arguments:3
+
+   For an example of a way to make defining blind macros easier, see
+*note Composition::.
+
+   The macro ‘ifelse’ can take more than four arguments.  If given more
+than four arguments, ‘ifelse’ works like a ‘case’ or ‘switch’ statement
+in traditional programming languages.  If STRING-1 and STRING-2 are
+equal, ‘ifelse’ expands into EQUAL-1, otherwise the procedure is
+repeated with the first three arguments discarded.  This calls for an
+example:
+
+     ifelse(`foo', `bar', `third', `gnu', `gnats')
+     error→m4:stdin:1: Warning: excess arguments to builtin `ifelse' ignored
+     ⇒gnu
+     ifelse(`foo', `bar', `third', `gnu', `gnats', `sixth')
+     ⇒
+     ifelse(`foo', `bar', `third', `gnu', `gnats', `sixth', `seventh')
+     ⇒seventh
+     ifelse(`foo', `bar', `3', `gnu', `gnats', `6', `7', `8')
+     error→m4:stdin:4: Warning: excess arguments to builtin `ifelse' ignored
+     ⇒7
+
+   Naturally, the normal case will be slightly more advanced than these
+examples.  A common use of ‘ifelse’ is in macros implementing loops of
+various kinds.
+
+&#x1f;
+File: m4.info,  Node: Shift,  Next: Forloop,  Prev: Ifelse,  Up: Conditionals
+
+6.3 Recursion in ‘m4’
+=====================
+
+There is no direct support for loops in ‘m4’, but macros can be
+recursive.  There is no limit on the number of recursion levels, other
+than those enforced by your hardware and operating system.
+
+   Loops can be programmed using recursion and the conditionals
+described previously.
+
+   There is a builtin macro, ‘shift’, which can, among other things, be
+used for iterating through the actual arguments to a macro:
+
+ -- Builtin: shift (ARG1, ...)
+     Takes any number of arguments, and expands to all its arguments
+     except ARG1, separated by commas, with each argument quoted.
+
+     The macro ‘shift’ is recognized only with parameters.
+
+     shift
+     ⇒shift
+     shift(`bar')
+     ⇒
+     shift(`foo', `bar', `baz')
+     ⇒bar,baz
+
+   An example of the use of ‘shift’ is this macro:
+
+ -- Composite: reverse (...)
+     Takes any number of arguments, and reverses their order.
+
+   It is implemented as:
+
+     define(`reverse', `ifelse(`$#', `0', , `$#', `1', ``$1'',
+                               `reverse(shift($@)), `$1'')')
+     ⇒
+     reverse
+     ⇒
+     reverse(`foo')
+     ⇒foo
+     reverse(`foo', `bar', `gnats', `and gnus')
+     ⇒and gnus, gnats, bar, foo
+
+   While not a very interesting macro, it does show how simple loops can
+be made with ‘shift’, ‘ifelse’ and recursion.  It also shows that
+‘shift’ is usually used with ‘$@’.  Another example of this is an
+implementation of a short-circuiting conditional operator.
+
+ -- Composite: cond (TEST-1, STRING-1, EQUAL-1, TEST-2, STRING-2,
+          EQUAL-2, ..., NOT-EQUAL)
+     Similar to ‘ifelse’, where an equal comparison between the first
+     two strings results in the third, otherwise the first three
+     arguments are discarded and the process repeats.  The difference is
+     that each TEST-<N> is expanded only when it is encountered.  This
+     means that every third argument to ‘cond’ is normally given one
+     more level of quoting than the corresponding argument to ‘ifelse’.
+
+   Here is the implementation of ‘cond’, along with a demonstration of
+how it can short-circuit the side effects in ‘side’.  Notice how all the
+unquoted side effects happen regardless of how many comparisons are made
+with ‘ifelse’, compared with only the relevant effects with ‘cond’.
+
+     define(`cond',
+     `ifelse(`$#', `1', `$1',
+             `ifelse($1, `$2', `$3',
+                     `$0(shift(shift(shift($@))))')')')dnl
+     define(`side', `define(`counter', incr(counter))$1')dnl
+     define(`example1',
+     `define(`counter', `0')dnl
+     ifelse(side(`$1'), `yes', `one comparison: ',
+            side(`$1'), `no', `two comparisons: ',
+            side(`$1'), `maybe', `three comparisons: ',
+            `side(`default answer: ')')counter')dnl
+     define(`example2',
+     `define(`counter', `0')dnl
+     cond(`side(`$1')', `yes', `one comparison: ',
+          `side(`$1')', `no', `two comparisons: ',
+          `side(`$1')', `maybe', `three comparisons: ',
+          `side(`default answer: ')')counter')dnl
+     example1(`yes')
+     ⇒one comparison: 3
+     example1(`no')
+     ⇒two comparisons: 3
+     example1(`maybe')
+     ⇒three comparisons: 3
+     example1(`feeling rather indecisive today')
+     ⇒default answer: 4
+     example2(`yes')
+     ⇒one comparison: 1
+     example2(`no')
+     ⇒two comparisons: 2
+     example2(`maybe')
+     ⇒three comparisons: 3
+     example2(`feeling rather indecisive today')
+     ⇒default answer: 4
+
+   Another common task that requires iteration is joining a list of
+arguments into a single string.
+
+ -- Composite: join (SEPARATOR, ARGS...)
+ -- Composite: joinall (SEPARATOR, ARGS...)
+     Generate a single-quoted string, consisting of each ARG separated
+     by SEPARATOR.  While ‘joinall’ always outputs a SEPARATOR between
+     arguments, ‘join’ avoids the SEPARATOR for an empty ARG.
+
+   Here are some examples of its usage, based on the implementation
+‘m4-1.4.19/examples/join.m4’ distributed in this package:
+
+     $ m4 -I examples
+     include(`join.m4')
+     ⇒
+     join,join(`-'),join(`-', `'),join(`-', `', `')
+     ⇒,,,
+     joinall,joinall(`-'),joinall(`-', `'),joinall(`-', `', `')
+     ⇒,,,-
+     join(`-', `1')
+     ⇒1
+     join(`-', `1', `2', `3')
+     ⇒1-2-3
+     join(`', `1', `2', `3')
+     ⇒123
+     join(`-', `', `1', `', `', `2', `')
+     ⇒1-2
+     joinall(`-', `', `1', `', `', `2', `')
+     ⇒-1---2-
+     join(`,', `1', `2', `3')
+     ⇒1,2,3
+     define(`nargs', `$#')dnl
+     nargs(join(`,', `1', `2', `3'))
+     ⇒1
+
+   Examining the implementation shows some interesting points about
+several m4 programming idioms.
+
+     $ m4 -I examples
+     undivert(`join.m4')dnl
+     ⇒divert(`-1')
+     ⇒# join(sep, args) - join each non-empty ARG into a single
+     ⇒# string, with each element separated by SEP
+     ⇒define(`join',
+     ⇒`ifelse(`$#', `2', ``$2'',
+     ⇒  `ifelse(`$2', `', `', ``$2'_')$0(`$1', shift(shift($@)))')')
+     ⇒define(`_join',
+     ⇒`ifelse(`$#$2', `2', `',
+     ⇒  `ifelse(`$2', `', `', ``$1$2'')$0(`$1', shift(shift($@)))')')
+     ⇒# joinall(sep, args) - join each ARG, including empty ones,
+     ⇒# into a single string, with each element separated by SEP
+     ⇒define(`joinall', ``$2'_$0(`$1', shift($@))')
+     ⇒define(`_joinall',
+     ⇒`ifelse(`$#', `2', `', ``$1$3'$0(`$1', shift(shift($@)))')')
+     ⇒divert`'dnl
+
+   First, notice that this implementation creates helper macros ‘_join’
+and ‘_joinall’.  This division of labor makes it easier to output the
+correct number of SEPARATOR instances: ‘join’ and ‘joinall’ are
+responsible for the first argument, without a separator, while ‘_join’
+and ‘_joinall’ are responsible for all remaining arguments, always
+outputting a separator when outputting an argument.
+
+   Next, observe how ‘join’ decides to iterate to itself, because the
+first ARG was empty, or to output the argument and swap over to ‘_join’.
+If the argument is non-empty, then the nested ‘ifelse’ results in an
+unquoted ‘_’, which is concatenated with the ‘$0’ to form the next macro
+name to invoke.  The ‘joinall’ implementation is simpler since it does
+not have to suppress empty ARG; it always executes once then defers to
+‘_joinall’.
+
+   Another important idiom is the idea that SEPARATOR is reused for each
+iteration.  Each iteration has one less argument, but rather than
+discarding ‘$1’ by iterating with ‘$0(shift($@))’, the macro discards
+‘$2’ by using ‘$0(`$1', shift(shift($@)))’.
+
+   Next, notice that it is possible to compare more than one condition
+in a single ‘ifelse’ test.  The test of ‘$#$2’ against ‘2’ allows
+‘_join’ to iterate for two separate reasons—either there are still more
+than two arguments, or there are exactly two arguments but the last
+argument is not empty.
+
+   Finally, notice that these macros require exactly two arguments to
+terminate recursion, but that they still correctly result in empty
+output when given no ARGS (i.e., zero or one macro argument).  On the
+first pass when there are too few arguments, the ‘shift’ results in no
+output, but leaves an empty string to serve as the required second
+argument for the second pass.  Put another way, ‘`$1', shift($@)’ is not
+the same as ‘$@’, since only the former guarantees at least two
+arguments.
+
+   Sometimes, a recursive algorithm requires adding quotes to each
+element, or treating multiple arguments as a single element:
+
+ -- Composite: quote (...)
+ -- Composite: dquote (...)
+ -- Composite: dquote_elt (...)
+     Takes any number of arguments, and adds quoting.  With ‘quote’,
+     only one level of quoting is added, effectively removing whitespace
+     after commas and turning multiple arguments into a single string.
+     With ‘dquote’, two levels of quoting are added, one around each
+     element, and one around the list.  And with ‘dquote_elt’, two
+     levels of quoting are added around each element.
+
+   An actual implementation of these three macros is distributed as
+‘m4-1.4.19/examples/quote.m4’ in this package.  First, let’s examine
+their usage:
+
+     $ m4 -I examples
+     include(`quote.m4')
+     ⇒
+     -quote-dquote-dquote_elt-
+     ⇒----
+     -quote()-dquote()-dquote_elt()-
+     ⇒--`'-`'-
+     -quote(`1')-dquote(`1')-dquote_elt(`1')-
+     ⇒-1-`1'-`1'-
+     -quote(`1', `2')-dquote(`1', `2')-dquote_elt(`1', `2')-
+     ⇒-1,2-`1',`2'-`1',`2'-
+     define(`n', `$#')dnl
+     -n(quote(`1', `2'))-n(dquote(`1', `2'))-n(dquote_elt(`1', `2'))-
+     ⇒-1-1-2-
+     dquote(dquote_elt(`1', `2'))
+     ⇒``1'',``2''
+     dquote_elt(dquote(`1', `2'))
+     ⇒``1',`2''
+
+   The last two lines show that when given two arguments, ‘dquote’
+results in one string, while ‘dquote_elt’ results in two.  Now, examine
+the implementation.  Note that ‘quote’ and ‘dquote_elt’ make decisions
+based on their number of arguments, so that when called without
+arguments, they result in nothing instead of a quoted empty string; this
+is so that it is possible to distinguish between no arguments and an
+empty first argument.  ‘dquote’, on the other hand, results in a string
+no matter what, since it is still possible to tell whether it was
+invoked without arguments based on the resulting string.
+
+     $ m4 -I examples
+     undivert(`quote.m4')dnl
+     ⇒divert(`-1')
+     ⇒# quote(args) - convert args to single-quoted string
+     ⇒define(`quote', `ifelse(`$#', `0', `', ``$*'')')
+     ⇒# dquote(args) - convert args to quoted list of quoted strings
+     ⇒define(`dquote', ``$@'')
+     ⇒# dquote_elt(args) - convert args to list of double-quoted strings
+     ⇒define(`dquote_elt', `ifelse(`$#', `0', `', `$#', `1', ```$1''',
+     ⇒                             ```$1'',$0(shift($@))')')
+     ⇒divert`'dnl
+
+   It is worth pointing out that ‘quote(ARGS)’ is more efficient than
+‘joinall(`,', ARGS)’ for producing the same output.
+
+   One more useful macro based on ‘shift’ allows portably selecting an
+arbitrary argument (usually greater than the ninth argument), without
+relying on the GNU extension of multi-digit arguments (*note
+Arguments::).
+
+ -- Composite: argn (N, ...)
+     Expands to argument N out of the remaining arguments.  N must be a
+     positive number.  Usually invoked as ‘argn(`N',$@)’.
+
+   It is implemented as:
+
+     define(`argn', `ifelse(`$1', 1, ``$2'',
+       `argn(decr(`$1'), shift(shift($@)))')')
+     ⇒
+     argn(`1', `a')
+     ⇒a
+     define(`foo', `argn(`11', $@)')
+     ⇒
+     foo(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k', `l')
+     ⇒k
+
+&#x1f;

+
+6.4 Iteration by counting
+=========================
+
+Here is an example of a loop macro that implements a simple for loop.
+
+ -- Composite: forloop (ITERATOR, START, END, TEXT)
+     Takes the name in ITERATOR, which must be a valid macro name, and
+     successively assign it each integer value from START to END,
+     inclusive.  For each assignment to ITERATOR, append TEXT to the
+     expansion of the ‘forloop’.  TEXT may refer to ITERATOR.  Any
+     definition of ITERATOR prior to this invocation is restored.
+
+   It can, for example, be used for simple counting:
+
+     $ m4 -I examples
+     include(`forloop.m4')
+     ⇒
+     forloop(`i', `1', `8', `i ')
+     ⇒1 2 3 4 5 6 7 8 
+
+   For-loops can be nested, like:
+
+     $ m4 -I examples
+     include(`forloop.m4')
+     ⇒
+     forloop(`i', `1', `4', `forloop(`j', `1', `8', ` (i, j)')
+     ')
+     ⇒ (1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6) (1, 7) (1, 8)
+     ⇒ (2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6) (2, 7) (2, 8)
+     ⇒ (3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) (3, 7) (3, 8)
+     ⇒ (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6) (4, 7) (4, 8)
+     ⇒
+
+   The implementation of the ‘forloop’ macro is fairly straightforward.
+The ‘forloop’ macro itself is simply a wrapper, which saves the previous
+definition of the first argument, calls the internal macro ‘_forloop’,
+and re-establishes the saved definition of the first argument.
+
+   The macro ‘_forloop’ expands the fourth argument once, and tests to
+see if the iterator has reached the final value.  If it has not
+finished, it increments the iterator (using the predefined macro ‘incr’,
+*note Incr::), and recurses.
+
+   Here is an actual implementation of ‘forloop’, distributed as
+‘m4-1.4.19/examples/forloop.m4’ in this package:
+
+     $ m4 -I examples
+     undivert(`forloop.m4')dnl
+     ⇒divert(`-1')
+     ⇒# forloop(var, from, to, stmt) - simple version
+     ⇒define(`forloop', `pushdef(`$1', `$2')_forloop($@)popdef(`$1')')
+     ⇒define(`_forloop',
+     ⇒       `$4`'ifelse($1, `$3', `', `define(`$1', incr($1))$0($@)')')
+     ⇒divert`'dnl
+
+   Notice the careful use of quotes.  Certain macro arguments are left
+unquoted, each for its own reason.  Try to find out _why_ these
+arguments are left unquoted, and see what happens if they are quoted.
+(As presented, these two macros are useful but not very robust for
+general use.  They lack even basic error handling for cases like START
+less than END, END not numeric, or ITERATOR not being a macro name.  See
+if you can improve these macros; or *note Answers: Improved forloop.).

+
+6.5 Iteration by list contents
+==============================
+
+Here is an example of a loop macro that implements list iteration.
+
+ -- Composite: foreach (ITERATOR, PAREN-LIST, TEXT)
+ -- Composite: foreachq (ITERATOR, QUOTE-LIST, TEXT)
+     Takes the name in ITERATOR, which must be a valid macro name, and
+     successively assign it each value from PAREN-LIST or QUOTE-LIST.
+     In ‘foreach’, PAREN-LIST is a comma-separated list of elements
+     contained in parentheses.  In ‘foreachq’, QUOTE-LIST is a
+     comma-separated list of elements contained in a quoted string.  For
+     each assignment to ITERATOR, append TEXT to the overall expansion.
+     TEXT may refer to ITERATOR.  Any definition of ITERATOR prior to
+     this invocation is restored.
+
+   As an example, this displays each word in a list inside of a
+sentence, using an implementation of ‘foreach’ distributed as
+‘m4-1.4.19/examples/foreach.m4’, and ‘foreachq’ in
+‘m4-1.4.19/examples/foreachq.m4’.
+
+     $ m4 -I examples
+     include(`foreach.m4')
+     ⇒
+     foreach(`x', (foo, bar, foobar), `Word was: x
+     ')dnl
+     ⇒Word was: foo
+     ⇒Word was: bar
+     ⇒Word was: foobar
+     include(`foreachq.m4')
+     ⇒
+     foreachq(`x', `foo, bar, foobar', `Word was: x
+     ')dnl
+     ⇒Word was: foo
+     ⇒Word was: bar
+     ⇒Word was: foobar
+
+   It is possible to be more complex; each element of the PAREN-LIST or
+QUOTE-LIST can itself be a list, to pass as further arguments to a
+helper macro.  This example generates a shell case statement:
+
+     $ m4 -I examples
+     include(`foreach.m4')
+     ⇒
+     define(`_case', `  $1)
+         $2=" $1";;
+     ')dnl
+     define(`_cat', `$1$2')dnl
+     case $`'1 in
+     ⇒case $1 in
+     foreach(`x', `(`(`a', `vara')', `(`b', `varb')', `(`c', `varc')')',
+             `_cat(`_case', x)')dnl
+     ⇒  a)
+     ⇒    vara=" a";;
+     ⇒  b)
+     ⇒    varb=" b";;
+     ⇒  c)
+     ⇒    varc=" c";;
+     esac
+     ⇒esac
+
+   The implementation of the ‘foreach’ macro is a bit more involved; it
+is a wrapper around two helper macros.  First, ‘_arg1’ is needed to grab
+the first element of a list.  Second, ‘_foreach’ implements the
+recursion, successively walking through the original list.  Here is a
+simple implementation of ‘foreach’:
+
+     $ m4 -I examples
+     undivert(`foreach.m4')dnl
+     ⇒divert(`-1')
+     ⇒# foreach(x, (item_1, item_2, ..., item_n), stmt)
+     ⇒#   parenthesized list, simple version
+     ⇒define(`foreach', `pushdef(`$1')_foreach($@)popdef(`$1')')
+     ⇒define(`_arg1', `$1')
+     ⇒define(`_foreach', `ifelse(`$2', `()', `',
+     ⇒  `define(`$1', _arg1$2)$3`'$0(`$1', (shift$2), `$3')')')
+     ⇒divert`'dnl
+
+   Unfortunately, that implementation is not robust to macro names as
+list elements.  Each iteration of ‘_foreach’ is stripping another layer
+of quotes, leading to erratic results if list elements are not already
+fully expanded.  The first cut at implementing ‘foreachq’ takes this
+into account.  Also, when using quoted elements in a PAREN-LIST, the
+overall list must be quoted.  A QUOTE-LIST has the nice property of
+requiring fewer characters to create a list containing the same quoted
+elements.  To see the difference between the two macros, we attempt to
+pass double-quoted macro names in a list, expecting the macro name on
+output after one layer of quotes is removed during list iteration and
+the final layer removed during the final rescan:
+
+     $ m4 -I examples
+     define(`a', `1')define(`b', `2')define(`c', `3')
+     ⇒
+     include(`foreach.m4')
+     ⇒
+     include(`foreachq.m4')
+     ⇒
+     foreach(`x', `(``a'', ``(b'', ``c)'')', `x
+     ')
+     ⇒1
+     ⇒(2)1
+     ⇒
+     ⇒, x
+     ⇒)
+     foreachq(`x', ```a'', ``(b'', ``c)''', `x
+     ')dnl
+     ⇒a
+     ⇒(b
+     ⇒c)
+
+   Obviously, ‘foreachq’ did a better job; here is its implementation:
+
+     $ m4 -I examples
+     undivert(`foreachq.m4')dnl
+     ⇒include(`quote.m4')dnl
+     ⇒divert(`-1')
+     ⇒# foreachq(x, `item_1, item_2, ..., item_n', stmt)
+     ⇒#   quoted list, simple version
+     ⇒define(`foreachq', `pushdef(`$1')_foreachq($@)popdef(`$1')')
+     ⇒define(`_arg1', `$1')
+     ⇒define(`_foreachq', `ifelse(quote($2), `', `',
+     ⇒  `define(`$1', `_arg1($2)')$3`'$0(`$1', `shift($2)', `$3')')')
+     ⇒divert`'dnl
+
+   Notice that ‘_foreachq’ had to use the helper macro ‘quote’ defined
+earlier (*note Shift::), to ensure that the embedded ‘ifelse’ call does
+not go haywire if a list element contains a comma.  Unfortunately, this
+implementation of ‘foreachq’ has its own severe flaw.  Whereas the
+‘foreach’ implementation was linear, this macro is quadratic in the
+number of list elements, and is much more likely to trip up the limit
+set by the command line option ‘--nesting-limit’ (or ‘-L’, *note
+Invoking m4: Limits control.).  Additionally, this implementation does
+not expand ‘defn(`ITERATOR')’ very well, when compared with ‘foreach’.
+
+     $ m4 -I examples
+     include(`foreach.m4')include(`foreachq.m4')
+     ⇒
+     foreach(`name', `(`a', `b')', ` defn(`name')')
+     ⇒ a b
+     foreachq(`name', ``a', `b'', ` defn(`name')')
+     ⇒ _arg1(`a', `b') _arg1(shift(`a', `b'))
+
+   It is possible to have robust iteration with linear behavior and sane
+ITERATOR contents for either list style.  See if you can learn from the
+best elements of both of these implementations to create robust macros
+(or *note Answers: Improved foreach.).

+
+6.6 Working with definition stacks
+==================================
+
+Thanks to ‘pushdef’, manipulation of a stack is an intrinsic operation
+in ‘m4’.  Normally, only the topmost definition in a stack is important,
+but sometimes, it is desirable to manipulate the entire definition
+stack.
+
+ -- Composite: stack_foreach (MACRO, ACTION)
+ -- Composite: stack_foreach_lifo (MACRO, ACTION)
+     For each of the ‘pushdef’ definitions associated with MACRO, invoke
+     the macro ACTION with a single argument of that definition.
+     ‘stack_foreach’ visits the oldest definition first, while
+     ‘stack_foreach_lifo’ visits the current definition first.  ACTION
+     should not modify or dereference MACRO.  There are a few special
+     macros, such as ‘defn’, which cannot be used as the MACRO
+     parameter.
+
+   A sample implementation of these macros is distributed in the file
+‘m4-1.4.19/examples/stack.m4’.
+
+     $ m4 -I examples
+     include(`stack.m4')
+     ⇒
+     pushdef(`a', `1')pushdef(`a', `2')pushdef(`a', `3')
+     ⇒
+     define(`show', ``$1'
+     ')
+     ⇒
+     stack_foreach(`a', `show')dnl
+     ⇒1
+     ⇒2
+     ⇒3
+     stack_foreach_lifo(`a', `show')dnl
+     ⇒3
+     ⇒2
+     ⇒1
+
+   Now for the implementation.  Note the definition of a helper macro,
+‘_stack_reverse’, which destructively swaps the contents of one stack of
+definitions into the reverse order in the temporary macro ‘tmp-$1’.  By
+calling the helper twice, the original order is restored back into the
+macro ‘$1’; since the operation is destructive, this explains why ‘$1’
+must not be modified or dereferenced during the traversal.  The caller
+can then inject additional code to pass the definition currently being
+visited to ‘$2’.  The choice of helper names is intentional; since ‘-’
+is not valid as part of a macro name, there is no risk of conflict with
+a valid macro name, and the code is guaranteed to use ‘defn’ where
+necessary.  Finally, note that any macro used in the traversal of a
+‘pushdef’ stack, such as ‘pushdef’ or ‘defn’, cannot be handled by
+‘stack_foreach’, since the macro would temporarily be undefined during
+the algorithm.
+
+     $ m4 -I examples
+     undivert(`stack.m4')dnl
+     ⇒divert(`-1')
+     ⇒# stack_foreach(macro, action)

+
+6.7 Building macros with macros
+===============================
+
+Since m4 is a macro language, it is possible to write macros that can
+build other macros.  First on the list is a way to automate the creation
+of blind macros.
+
+ -- Composite: define_blind (NAME, VALUE)
+     Defines NAME as a blind macro, such that NAME will expand to VALUE
+     only when given explicit arguments.  VALUE should not be the result
+     of ‘defn’ (*note Defn::).  This macro is only recognized with
+     parameters, and results in an empty string.
+
+   Defining a macro to define another macro can be a bit tricky.  We
+want to use a literal ‘$#’ in the argument to the nested ‘define’.
+However, if ‘$’ and ‘#’ are adjacent in the definition of
+‘define_blind’, then it would be expanded as the number of arguments to
+‘define_blind’ rather than the intended number of arguments to NAME.
+The solution is to pass the difficult characters through extra arguments
+to a helper macro ‘_define_blind’.  When composing macros, it is a
+common idiom to need a helper macro to concatenate text that forms
+parameters in the composed macro, rather than interpreting the text as a
+parameter of the composing macro.
+
+   As for the limitation against using ‘defn’, there are two reasons.
+If a macro was previously defined with ‘define_blind’, then it can
+safely be renamed to a new blind macro using plain ‘define’; using
+‘define_blind’ to rename it just adds another layer of ‘ifelse’,
+occupying memory and slowing down execution.  And if a macro is a
+builtin, then it would result in an attempt to define a macro consisting
+of both text and a builtin token; this is not supported, and the builtin
+token is flattened to an empty string.
+
+   With that explanation, here’s the definition, and some sample usage.
+Notice that ‘define_blind’ is itself a blind macro.
+
+     $ m4 -d
+     define(`define_blind', `ifelse(`$#', `0', ``$0'',
+     `_$0(`$1', `$2', `$'`#', `$'`0')')')
+     ⇒
+     define(`_define_blind', `define(`$1',
+     `ifelse(`$3', `0', ``$4'', `$2')')')
+     ⇒
+     define_blind
+     ⇒define_blind
+     define_blind(`foo', `arguments were $*')
+     ⇒
+     foo
+     ⇒foo
+     foo(`bar')
+     ⇒arguments were bar
+     define(`blah', defn(`foo'))
+     ⇒
+     blah
+     ⇒blah
+     blah(`a', `b')
+     ⇒arguments were a,b
+     defn(`blah')
+     ⇒ifelse(`$#', `0', ``$0'', `arguments were $*')
+
+   Another interesting composition tactic is argument “currying”, or
+factoring a macro that takes multiple arguments for use in a context
+that provides exactly one argument.
+
+ -- Composite: curry (MACRO, ...)
+     Expand to a macro call that takes exactly one argument, then
+     appends that argument to the original arguments and invokes MACRO
+     with the resulting list of arguments.
+
+   A demonstration of currying makes the intent of this macro a little
+more obvious.  The macro ‘stack_foreach’ mentioned earlier is an example
+of a context that provides exactly one argument to a macro name.  But
+coupled with currying, we can invoke ‘reverse’ with two arguments for
+each definition of a macro stack.  This example uses the file
+‘m4-1.4.19/examples/curry.m4’ included in the distribution.
+
+     $ m4 -I examples
+     include(`curry.m4')include(`stack.m4')
+     ⇒
+     define(`reverse', `ifelse(`$#', `0', , `$#', `1', ``$1'',
+                               `reverse(shift($@)), `$1'')')
+     ⇒
+     pushdef(`a', `1')pushdef(`a', `2')pushdef(`a', `3')
+     ⇒
+     stack_foreach(`a', `:curry(`reverse', `4')')
+     ⇒:1, 4:2, 4:3, 4
+     curry(`curry', `reverse', `1')(`2')(`3')
+     ⇒3, 2, 1
+
+   Now for the implementation.  Notice how ‘curry’ leaves off with a
+macro name but no open parenthesis, while still in the middle of
+collecting arguments for ‘$1’.  The macro ‘_curry’ is the helper macro
+that takes one argument, then adds it to the list and finally supplies
+the closing parenthesis.  The use of a comma inside the ‘shift’ call
+allows currying to also work for a macro that takes one argument,
+although it often makes more sense to invoke that macro directly rather
+than going through ‘curry’.
+
+     $ m4 -I examples
+     undivert(`curry.m4')dnl
+     ⇒divert(`-1')
+     ⇒# curry(macro, args)
+     ⇒# Expand to a macro call that takes one argument, then invoke
+     ⇒# macro(args, extra).
+     ⇒define(`curry', `$1(shift($@,)_$0')
+     ⇒define(`_curry', ``$1')')
+     ⇒divert`'dnl
+
+   Unfortunately, with M4 1.4.x, ‘curry’ is unable to handle builtin
+tokens, which are silently flattened to the empty string when passed
+through another text macro.  This limitation will be lifted in a future
+release of M4.
+
+   Putting the last few concepts together, it is possible to copy or
+rename an entire stack of macro definitions.
+
+ -- Composite: copy (SOURCE, DEST)
+ -- Composite: rename (SOURCE, DEST)
+     Ensure that DEST is undefined, then define it to the same stack of
+     definitions currently in SOURCE.  ‘copy’ leaves SOURCE unchanged,
+     while ‘rename’ undefines SOURCE.  There are only a few macros, such
+     as ‘copy’ or ‘defn’, which cannot be copied via this macro.
+
+   The implementation is relatively straightforward (although since it
+uses ‘curry’, it is unable to copy builtin macros, such as the second
+definition of ‘a’ as a synonym for ‘divnum’.  See if you can design a
+version that works around this limitation, or *note Answers: Improved
+copy.).
+
+     $ m4 -I examples
+     include(`curry.m4')include(`stack.m4')
+     ⇒
+     define(`rename', `copy($@)undefine(`$1')')dnl
+     define(`copy', `ifdef(`$2', `errprint(`$2 already defined
+     ')m4exit(`1')',
+        `stack_foreach(`$1', `curry(`pushdef', `$2')')')')dnl
+     pushdef(`a', `1')pushdef(`a', defn(`divnum'))pushdef(`a', `2')
+     ⇒
+     copy(`a', `b')
+     ⇒
+     rename(`b', `c')
+     ⇒
+     a b c
+     ⇒2 b 2
+     popdef(`a', `c')c a
+     ⇒ 0
+     popdef(`a', `c')a c
+     ⇒1 1

+7 How to debug macros and input
+*******************************
+
+When writing macros for ‘m4’, they often do not work as intended on the
+first try (as is the case with most programming languages).
+Fortunately, there is support for macro debugging in ‘m4’.
+
+* Menu:
+
+* Dumpdef::                     Displaying macro definitions
+* Trace::                       Tracing macro calls
+* Debug Levels::                Controlling debugging output
+* Debug Output::                Saving debugging output
+
+&#x1f;
+File: m4.info,  Node: Dumpdef,  Next: Trace,  Up: Debugging
+
+7.1 Displaying macro definitions
+================================
+
+If you want to see what a name expands into, you can use the builtin
+‘dumpdef’:
+
+ -- Builtin: dumpdef (NAMES...)
+     Accepts any number of arguments.  If called without any arguments,
+     it displays the definitions of all known names, otherwise it
+     displays the definitions of the NAMES given.  The output is printed
+     to the current debug file (usually standard error), and is sorted
+     by name.  If an unknown name is encountered, a warning is printed.
+
+     The expansion of ‘dumpdef’ is void.
+
+     $ m4 -d
+     define(`foo', `Hello world.')
+     ⇒
+     dumpdef(`foo')
+     error→foo: ⇒
+     dumpdef(`define')
+     error→define: ⇒
+
+   The last example shows how builtin macros definitions are displayed.
+The definition that is dumped corresponds to what would occur if the
+macro were to be called at that point, even if other definitions are
+still live due to redefining a macro during argument collection.
+
+     $ m4 -d
+     pushdef(`f', ``$0'1')pushdef(`f', ``$0'2')
+     ⇒
+     f(popdef(`f')dumpdef(`f'))
+     error→f: ⇒f2
+     f(popdef(`f')dumpdef(`f'))
+     error→m4:stdin:3: undefined macro `f'
+     ⇒f1
+
+   *Note Debug Levels::, for information on controlling the details of
+the display.

+&#x1f;
+File: m4.info,  Node: Trace,  Next: Debug Levels,  Prev: Dumpdef,  Up: Debugging
+
+7.2 Tracing macro calls
+=======================
+
+It is possible to trace macro calls and expansions through the builtins
+‘traceon’ and ‘traceoff’:
+
+ -- Builtin: traceon (NAMES...)
+ -- Builtin: traceoff (NAMES...)
+     When called without any arguments, ‘traceon’ and ‘traceoff’ will
+     turn tracing on and off, respectively, for all currently defined
+     macros.
+
+     When called with arguments, only the macros listed in NAMES are
+     affected, whether or not they are currently defined.
+
+     The expansion of ‘traceon’ and ‘traceoff’ is void.
+
+   Whenever a traced macro is called and the arguments have been
+collected, the call is displayed.  If the expansion of the macro call is
+not void, the expansion can be displayed after the call.  The output is
+printed to the current debug file (defaulting to standard error, *note
+Debug Output::).
+
+     $ m4 -d
+     define(`foo', `Hello World.')
+     ⇒
+     define(`echo', `$@')
+     ⇒
+     traceon(`foo', `echo')
+     ⇒
+     foo
+     error→m4trace: -1- foo -> `Hello World.'
+     ⇒Hello World.
+     echo(`gnus', `and gnats')
+     error→m4trace: -1- echo(`gnus', `and gnats') -> ``gnus',`and gnats''
+     ⇒gnus,and gnats
+
+   The number between dashes is the depth of the expansion.  It is one
+most of the time, signifying an expansion at the outermost level, but it
+increases when macro arguments contain unquoted macro calls.  The
+maximum number that will appear between dashes is controlled by the
+option ‘--nesting-limit’ (or ‘-L’, *note Invoking m4: Limits control.).
+Additionally, the option ‘--trace’ (or ‘-t’) can be used to invoke
+‘traceon(NAME)’ before parsing input.
+
+     $ m4 -L 3 -t ifelse
+     ifelse(`one level')
+     error→m4trace: -1- ifelse
+     ⇒
+     ifelse(ifelse(ifelse(`three levels')))
+     error→m4trace: -3- ifelse
+     error→m4trace: -2- ifelse
+     error→m4trace: -1- ifelse
+     ⇒
+     ifelse(ifelse(ifelse(ifelse(`four levels'))))
+     error→m4:stdin:3: recursion limit of 3 exceeded, use -L<N> to change it
+
+   Tracing by name is an attribute that is preserved whether the macro
+is defined or not.  This allows the selection of macros to trace before
+those macros are defined.
+
+     $ m4 -d
+     traceoff(`foo')
+     ⇒
+     traceon(`foo')
+     ⇒
+     foo
+     ⇒foo
+     defn(`foo')
+     ⇒
+     define(`foo', `bar')
+     ⇒
+     foo
+     error→m4trace: -1- foo -> `bar'
+     ⇒bar
+     undefine(`foo')
+     ⇒
+     ifdef(`foo', `yes', `no')
+     ⇒no
+     indir(`foo')
+     error→m4:stdin:9: undefined macro `foo'
+     ⇒
+     define(`foo', `blah')
+     ⇒
+     foo
+     error→m4trace: -1- foo -> `blah'
+     ⇒blah
+     traceoff
+     ⇒
+     foo
+     ⇒blah
+
+   Tracing even works on builtins.  However, ‘defn’ (*note Defn::) does
+not transfer tracing status.
+
+     $ m4 -d
+     traceon(`traceon')
+     ⇒
+     traceon(`traceoff')
+     error→m4trace: -1- traceon(`traceoff')
+     ⇒
+     traceoff(`traceoff')
+     error→m4trace: -1- traceoff(`traceoff')
+     ⇒
+     traceoff(`traceon')
+     ⇒
+     traceon(`eval', `m4_divnum')
+     ⇒
+     define(`m4_eval', defn(`eval'))
+     ⇒
+     define(`m4_divnum', defn(`divnum'))
+     ⇒
+     eval(divnum)
+     error→m4trace: -1- eval(`0') -> `0'
+     ⇒0
+     m4_eval(m4_divnum)
+     error→m4trace: -2- m4_divnum -> `0'
+     ⇒0
+
+   *Note Debug Levels::, for information on controlling the details of
+the display.  The format of the trace output is not specified by POSIX,
+and varies between implementations of ‘m4’.
+
+&#x1f;
+File: m4.info,  Node: Debug Levels,  Next: Debug Output,  Prev: Trace,  Up: Debugging
+
+7.3 Controlling debugging output
+================================
+
+The ‘-d’ option to ‘m4’ (or ‘--debug’, *note Invoking m4: Debugging
+options.) controls the amount of details presented in three categories
+of output.  Trace output is requested by ‘traceon’ (*note Trace::), and
+each line is prefixed by ‘m4trace:’ in relation to a macro invocation.
+Debug output tracks useful events not associated with a macro
+invocation, and each line is prefixed by ‘m4debug:’.  Finally, ‘dumpdef’
+(*note Dumpdef::) output is affected, with no prefix added to the output
+lines.
+
+   The FLAGS following the option can be one or more of the following:
+
+‘a’
+     In trace output, show the actual arguments that were collected
+     before invoking the macro.  This applies to all macro calls if the
+     ‘t’ flag is used, otherwise only the macros covered by calls of
+     ‘traceon’.  Arguments are subject to length truncation specified by
+     the command line option ‘--arglength’ (or ‘-l’).
+
+‘c’
+     In trace output, show several trace lines for each macro call.  A
+     line is shown when the macro is seen, but before the arguments are
+     collected; a second line when the arguments have been collected and
+     a third line after the call has completed.
+
+‘e’
+     In trace output, show the expansion of each macro call, if it is
+     not void.  This applies to all macro calls if the ‘t’ flag is used,
+     otherwise only the macros covered by calls of ‘traceon’.  The
+     expansion is subject to length truncation specified by the command
+     line option ‘--arglength’ (or ‘-l’).
+
+‘f’
+     In debug and trace output, include the name of the current input
+     file in the output line.
+
+‘i’
+     In debug output, print a message each time the current input file
+     is changed.
+
+‘l’
+     In debug and trace output, include the current input line number in
+     the output line.
+
+‘p’
+     In debug output, print a message when a named file is found through
+     the path search mechanism (*note Search Path::), giving the actual
+     file name used.
+
+‘q’
+     In trace and dumpdef output, quote actual arguments and macro
+     expansions in the display with the current quotes.  This is useful
+     in connection with the ‘a’ and ‘e’ flags above.
+
+‘t’
+     In trace output, trace all macro calls made in this invocation of
+     ‘m4’, regardless of the settings of ‘traceon’.
+
+‘x’
+     In trace output, add a unique ‘macro call id’ to each line of the
+     trace output.  This is useful in connection with the ‘c’ flag
+     above.
+
+‘V’
+     A shorthand for all of the above flags.
+
+   If no flags are specified with the ‘-d’ option, the default is ‘aeq’.
+The examples throughout this manual assume the default flags.
+
+   There is a builtin macro ‘debugmode’, which allows on-the-fly control
+of the debugging output format:
+
+ -- Builtin: debugmode (FLAGS)
+     The argument FLAGS should be a subset of the letters listed above.
+     As special cases, if the argument starts with a ‘+’, the flags are
+     added to the current debug flags, and if it starts with a ‘-’, they
+     are removed.  If no argument is present, all debugging flags are
+     cleared (as if no ‘-d’ was given), and with an empty argument the
+     flags are reset to the default of ‘aeq’.
+
+     The expansion of ‘debugmode’ is void.

+7.4 Saving debugging output
+===========================
+
+Debug and tracing output can be redirected to files using either the
+‘--debugfile’ option to ‘m4’ (*note Invoking m4: Debugging options.), or
+with the builtin macro ‘debugfile’:
+
+ -- Builtin: debugfile (FILE)
+     Sends all further debug and trace output to FILE, opened in append
+     mode.  If FILE is the empty string, debug and trace output are
+     discarded.  If ‘debugfile’ is called without any arguments, debug
+     and trace output are sent to standard error.  This does not affect
+     warnings, error messages, or ‘errprint’ output, which are always
+     sent to standard error.  If FILE cannot be opened, the current
+     debug file is unchanged, and an error is issued.
+
+     The expansion of ‘debugfile’ is void.

+
+8.1 Deleting whitespace in input
+================================
+
+The builtin ‘dnl’ stands for “Discard to Next Line”:
+
+ -- Builtin: dnl
+     All characters, up to and including the next newline, are discarded
+     without performing any macro expansion.  A warning is issued if the
+     end of the file is encountered without a newline.
+
+     The expansion of ‘dnl’ is void.
+
+   It is often used in connection with ‘define’, to remove the newline
+that follows the call to ‘define’.  Thus
+
+     define(`foo', `Macro `foo'.')dnl A very simple macro, indeed.
+     foo
+     ⇒Macro foo.
+
+   The input up to and including the next newline is discarded, as
+opposed to the way comments are treated (*note Comments::).
+
+   Usually, ‘dnl’ is immediately followed by an end of line or some
+other whitespace.  GNU ‘m4’ will produce a warning diagnostic if ‘dnl’
+is followed by an open parenthesis.  In this case, ‘dnl’ will collect
+and process all arguments, looking for a matching close parenthesis.
+All predictable side effects resulting from this collection will take
+place.  ‘dnl’ will return no output.  The input following the matching
+close parenthesis up to and including the next newline, on whatever line
+containing it, will still be discarded.
+
+     dnl(`args are ignored, but side effects occur',
+     define(`foo', `like this')) while this text is ignored: undefine(`foo')
+     error→m4:stdin:1: Warning: excess arguments to builtin `dnl' ignored
+     See how `foo' was defined, foo?
+     ⇒See how foo was defined, like this?
+
+   If the end of file is encountered without a newline character, a
+warning is issued and dnl stops consuming input.
+
+     m4wrap(`m4wrap(`2 hi
+     ')0 hi dnl 1 hi')
+     ⇒
+     define(`hi', `HI')

+     error→m4:stdin:1: Warning: end of file treated as newline

+
+8.2 Changing the quote characters
+=================================
+
+The default quote delimiters can be changed with the builtin
+‘changequote’:
+
+ -- Builtin: changequote (START = ‘`’, END = ‘'’)
+     This sets START as the new begin-quote delimiter and END as the new
+     end-quote delimiter.  If both arguments are missing, the default
+     quotes (‘`’ and ‘'’) are used.  If START is void, then quoting is
+     disabled.  Otherwise, if END is missing or void, the default
+     end-quote delimiter (‘'’) is used.  The quote delimiters can be of
+     any length.
+
+     The expansion of ‘changequote’ is void.
+
+     changequote(`', `')
+     ⇒
+     define(foo, Macro foo.)
+     ⇒
+     foo
+     ⇒Macro foo.
+
+   The quotation strings can safely contain non-ASCII characters.
+
+     define(`a', `b')
+     ⇒
+     «a»
+     ⇒«b»
+     changequote(`«', `»')
+     ⇒
+     «a»
+     ⇒a
+
+   If no single character is appropriate, START and END can be of any
+length.  Other implementations cap the delimiter length to five
+characters, but GNU has no inherent limit.
+
+     changequote(`', `')
+     ⇒
+     define(foo, Macro foo.)
+     ⇒
+     foo
+     ⇒Macro foo.
+
+   Calling ‘changequote’ with START as the empty string will effectively
+disable the quoting mechanism, leaving no way to quote text.  However,
+using an empty string is not portable, as some other implementations of
+‘m4’ revert to the default quoting, while others preserve the prior
+non-empty delimiter.  If START is not empty, then an empty END will use
+the default end-quote delimiter of ‘'’, as otherwise, it would be
+impossible to end a quoted string.  Again, this is not portable, as some
+other ‘m4’ implementations reuse START as the end-quote delimiter, while
+others preserve the previous non-empty value.  Omitting both arguments
+restores the default begin-quote and end-quote delimiters; fortunately
+this behavior is portable to all implementations of ‘m4’.
+
+     define(`foo', `Macro `FOO'.')
+     ⇒
+     changequote(`', `')
+     ⇒
+     foo
+     ⇒Macro `FOO'.
+     `foo'
+     ⇒`Macro `FOO'.'
+     changequote(`,)
+     ⇒
+     foo
+     ⇒Macro FOO.
+
+   There is no way in ‘m4’ to quote a string containing an unmatched
+begin-quote, except using ‘changequote’ to change the current quotes.
+
+   If the quotes should be changed from, say, ‘’ to ‘’, temporary
+quote characters have to be defined.  To achieve this, two calls of
+‘changequote’ must be made, one for the temporary quotes and one for the
+new quotes.
+
+   Macros are recognized in preference to the begin-quote string, so if
+a prefix of START can be recognized as part of a potential macro name,
+the quoting mechanism is effectively disabled.  Unless you use
+‘changeword’ (*note Changeword::), this means that START should not
+begin with a letter, digit, or ‘_’ (underscore).  However, even though
+quoted strings are not recognized, the quote characters can still be
+discerned in macro expansion and in trace output.
+
+     define(`echo', `$@')
+     ⇒
+     define(`hi', `HI')
+     ⇒
+     changequote(`q', `Q')
+     ⇒
+     q hi Q hi
+     ⇒q HI Q HI
+     echo(hi)
+     ⇒qHIQ
+     changequote
+     ⇒
+     changequote(`-', `EOF')
+     ⇒
+     - hi EOF hi
+     ⇒ hi  HI
+     changequote
+     ⇒
+     changequote(`1', `2')
+     ⇒
+     hi1hi2
+     ⇒hi1hi2
+     hi 1hi2
+     ⇒HI hi
+
+   Quotes are recognized in preference to argument collection.  In
+particular, if START is a single ‘(’, then argument collection is
+effectively disabled.  For portability with other implementations, it is
+a good idea to avoid ‘(’, ‘,’, and ‘)’ as the first character in START.
+
+     define(`echo', `$#:$@:')
+     ⇒
+     define(`hi', `HI')
+     ⇒
+     changequote(`(',`)')
+     ⇒
+     echo(hi)
+     ⇒0::hi
+     changequote
+     ⇒
+     changequote(`((', `))')
+     ⇒
+     echo(hi)
+     ⇒1:HI:
+     echo((hi))
+     ⇒0::hi
+     changequote
+     ⇒
+     changequote(`,', `)')
+     ⇒
+     echo(hi,hi)bye)
+     ⇒1:HIhibye:
+
+   However, if you are not worried about portability, using ‘(’ and ‘)’
+as quoting characters has an interesting property—you can use it to
+compute a quoted string containing the expansion of any quoted text, as
+long as the expansion results in both balanced quotes and balanced
+parentheses.  The trick is realizing ‘expand’ uses ‘$1’ unquoted, to
+trigger its expansion using the normal quoting characters, but uses
+extra parentheses to group unquoted commas that occur in the expansion
+without consuming whitespace following those commas.  Then ‘_expand’
+uses ‘changequote’ to convert the extra parentheses back into quoting
+characters.  Note that it takes two more ‘changequote’ invocations to
+restore the original quotes.  Contrast the behavior on whitespace when
+using ‘$*’, via ‘quote’, to attempt the same task.
+
+     changequote(`', `')dnl
+     define(a, 1, (b))dnl
+     define(b, 2)dnl
+     define(quote, $*)dnl
+     define(expand, _$0(($1)))dnl
+     define(_expand,
+       changequote((, ))$1changequote`'changequote(`', `'))dnl
+     expand(a, a, a, a, a, a)
+     ⇒1, (2), 1, (2), a, a, a, a
+     quote(a, a, a, a, a, a)
+     ⇒1,(2),1,(2),a, a,a, a
+
+   If END is a prefix of START, the end-quote will be recognized in
+preference to a nested begin-quote.  In particular, changing the quotes
+to have the same string for START and END disables nesting of quotes.
+When quote nesting is disabled, it is impossible to double-quote strings
+across macro expansions, so using the same string is not done very
+often.
+
+     define(`hi', `HI')
+     ⇒
+     changequote(`""', `"')
+     ⇒
+     ""hi"""hi"
+     ⇒hihi
+     ""hi" ""hi"
+     ⇒hi hi
+     ""hi"" "hi"
+     ⇒hi" "HI"
+     changequote
+     ⇒
+     `hi`hi'hi'
+     ⇒hi`hi'hi
+     changequote(`"', `"')
+     ⇒
+     "hi"hi"hi"
+     ⇒hiHIhi
+
+   It is an error if the end of file occurs within a quoted string.
+
+     `hello world'
+     ⇒hello world
+     `dangling quote
+     ^D

+
+8.3 Changing the comment delimiters
+===================================
+
+The default comment delimiters can be changed with the builtin macro
+‘changecom’:
+
+ -- Builtin: changecom (START, END = ‘<NL>’)
+     This sets START as the new begin-comment delimiter and END as the
+     new end-comment delimiter.  If both arguments are missing, or START
+     is void, then comments are disabled.  Otherwise, if END is missing
+     or void, the default end-comment delimiter of newline is used.  The
+     comment delimiters can be of any length.
+
+     The expansion of ‘changecom’ is void.
+
+     define(`comment', `COMMENT')
+     ⇒
+     # A normal comment
+     ⇒# A normal comment
+     changecom(`/*', `*/')
+     ⇒
+     # Not a comment anymore
+     ⇒# Not a COMMENT anymore
+     But: /* this is a comment now */ while this is not a comment
+     ⇒But: /* this is a comment now */ while this is not a COMMENT
+
+   Note how comments are copied to the output, much as if they were
+quoted strings.  If you want the text inside a comment expanded, quote
+the begin-comment delimiter.
+
+   Calling ‘changecom’ without any arguments, or with START as the empty
+string, will effectively disable the commenting mechanism.  To restore
+the original comment start of ‘#’, you must explicitly ask for it.  If
+START is not empty, then an empty END will use the default end-comment
+delimiter of newline, as otherwise, it would be impossible to end a
+comment.  However, this is not portable, as some other ‘m4’
+implementations preserve the previous non-empty delimiters instead.
+
+     define(`comment', `COMMENT')
+     ⇒
+     changecom
+     ⇒
+     # Not a comment anymore
+     ⇒# Not a COMMENT anymore
+     changecom(`#', `')
+     ⇒
+     # comment again
+     ⇒# comment again
+
+   The comment strings can safely contain non-ASCII characters.
+
+     define(`a', `b')
+     ⇒
+     «a»
+     ⇒«b»
+     changecom(`«', `»')
+     ⇒
+     «a»
+     ⇒«a»
+
+   If no single character is appropriate, START and END can be of any
+length.  Other implementations cap the delimiter length to five
+characters, but GNU has no inherent limit.
+
+   Comments are recognized in preference to macros.  However, this is
+not compatible with other implementations, where macros and even quoting
+takes precedence over comments, so it may change in a future release.
+For portability, this means that START should not begin with a letter,
+digit, or ‘_’ (underscore), and that neither the start-quote nor the
+start-comment string should be a prefix of the other.
+
+     define(`hi', `HI')
+     ⇒
+     define(`hi1hi2', `hello')
+     ⇒
+     changecom(`q', `Q')
+     ⇒
+     q hi Q hi
+     ⇒q hi Q HI
+     changecom(`1', `2')
+     ⇒
+     hi1hi2
+     ⇒hello
+     hi 1hi2
+     ⇒HI 1hi2
+
+   Comments are recognized in preference to argument collection.  In
+particular, if START is a single ‘(’, then argument collection is
+effectively disabled.  For portability with other implementations, it is
+a good idea to avoid ‘(’, ‘,’, and ‘)’ as the first character in START.
+
+     define(`echo', `$#:$*:$@:')
+     ⇒
+     define(`hi', `HI')

+8.4 Changing the lexical structure of words
+===========================================
+
+     The macro ‘changeword’ and all associated functionality is
+     experimental.  It is only available if the ‘--enable-changeword’
+     option was given to ‘configure’, at GNU ‘m4’ installation time.
+     The functionality will go away in the future, to be replaced by
+     other new features that are more efficient at providing the same
+     capabilities.  _Do not rely on it_.  Please direct your comments
+     about it the same way you would do for bugs.
+
+   A file being processed by ‘m4’ is split into quoted strings, words
+(potential macro names) and simple tokens (any other single character).
+Initially a word is defined by the following regular expression:
+
+     _a-zA-Z_a-zA-Z0-9*
+
+   Using ‘changeword’, you can change this regular expression:
+
+ -- Optional builtin: changeword (REGEX)
+     Changes the regular expression for recognizing macro names to be
+     REGEX.  If REGEX is empty, use ‘_a-zA-Z_a-zA-Z0-9*’.  REGEX
+     must obey the constraint that every prefix of the desired final
+     pattern is also accepted by the regular expression.  If REGEX
+     contains grouping parentheses, the macro invoked is the portion
+     that matched the first group, rather than the entire matching
+     string.
+
+     The expansion of ‘changeword’ is void.  The macro ‘changeword’ is
+     recognized only with parameters.
+
+   Relaxing the lexical rules of ‘m4’ might be useful (for example) if
+you wanted to apply translations to a file of numbers:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     changeword(`_a-zA-Z0-9+')
+     ⇒
+     define(`1', `0')1
+     ⇒0
+
+   Tightening the lexical rules is less useful, because it will
+generally make some of the builtins unavailable.  You could use it to
+prevent accidental call of builtins, for example:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     define(`_indir', defn(`indir'))
+     ⇒
+     changeword(`__a-zA-Z0-9*')
+     ⇒
+     esyscmd(`foo')
+     ⇒esyscmd(foo)
+     _indir(`esyscmd', `echo hi')
+     ⇒hi
+     ⇒
+
+   Because ‘m4’ constructs its words a character at a time, there is a
+restriction on the regular expressions that may be passed to
+‘changeword’.  This is that if your regular expression accepts ‘foo’, it
+must also accept ‘f’ and ‘fo’.
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     define(`foo
+     ', `bar
+     ')
+     ⇒
+     dnl This example wants to recognize changeword, dnl, and `foo\n'.
+     dnl First, we check that our regexp will match.
+     regexp(`changeword', `cda-z*\|foo
+     ')
+     ⇒0
+     regexp(`foo
+     ', `cda-z*\|foo
+     ')
+     ⇒0
+     regexp(`f', `cda-z*\|foo
+     ')
+     ⇒-1
+     foo
+     ⇒foo
+     changeword(`cda-z*\|foo
+     ')
+     ⇒
+     dnl Even though `foo\n' matches, we forgot to allow `f'.
+     foo
+     ⇒foo
+     changeword(`cda-z*\|fo*
+     ?')
+     ⇒
+     dnl Now we can call `foo\n'.
+     foo
+     ⇒bar
+
+   ‘changeword’ has another function.  If the regular expression
+supplied contains any grouped subexpressions, then text outside the
+first of these is discarded before symbol lookup.  So:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     ifdef(`__unix__', ,
+           `errprint(` skipping: syscmd does not have unix semantics
+     ')m4exit(`77')')dnl
+     changecom(`/*', `*/')dnl
+     define(`foo', `bar')dnl
+     changeword(`#$_a-zA-Z0-9*$')
+     ⇒
+     #esyscmd(`echo foo \#foo')
+     ⇒foo bar
+     ⇒
+
+   ‘m4’ now requires a ‘#’ mark at the beginning of every macro
+invocation, so one can use ‘m4’ to preprocess plain text without losing
+various words like ‘divert’.
+
+   In ‘m4’, macro substitution is based on text, while in TeX, it is
+based on tokens.  ‘changeword’ can throw this difference into relief.
+For example, here is the same idea represented in TeX and ‘m4’.  First,
+the TeX version:
+
+     \def\a{\message{Hello}}
+     \catcode`\@=0
+     \catcode`\\=12
+     @a
+     @bye
+     ⇒Hello
+
+Then, the ‘m4’ version:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     define(`a', `errprint(`Hello')')dnl
+     changeword(`@$_a-zA-Z0-9*$')
+     ⇒
+     @a
+     ⇒errprint(Hello)
+
+   In the TeX example, the first line defines a macro ‘a’ to print the
+message ‘Hello’.  The second line defines <@> to be usable instead of
+<\> as an escape character.  The third line defines <\> to be a normal
+printing character, not an escape.  The fourth line invokes the macro
+‘a’.  So, when TeX is run on this file, it displays the message ‘Hello’.
+
+   When the ‘m4’ example is passed through ‘m4’, it outputs
+‘errprint(Hello)’.  The reason for this is that TeX does lexical
+analysis of macro definition when the macro is _defined_.  ‘m4’ just
+stores the text, postponing the lexical analysis until the macro is
+_used_.
+
+   You should note that using ‘changeword’ will slow ‘m4’ down by a
+factor of about seven, once it is changed to something other than the
+default regular expression.  You can invoke ‘changeword’ with the empty
+string to restore the default word definition, and regain the parsing
+speed.

+
+8.5 Saving text until end of input
+==================================
+
+It is possible to ‘save’ some text until the end of the normal input has
+been seen.  Text can be saved, to be read again by ‘m4’ when the normal
+input has been exhausted.  This feature is normally used to initiate
+cleanup actions before normal exit, e.g., deleting temporary files.
+
+   To save input text, use the builtin ‘m4wrap’:
+
+ -- Builtin: m4wrap (STRING, ...)
+     Stores STRING in a safe place, to be reread when end of input is
+     reached.  As a GNU extension, additional arguments are concatenated
+     with a space to the STRING.
+
+     The expansion of ‘m4wrap’ is void.  The macro ‘m4wrap’ is
+     recognized only with parameters.
+
+     define(`cleanup', `This is the `cleanup' action.
+     ')
+     ⇒
+     m4wrap(`cleanup')
+     ⇒
+     This is the first and last normal input line.
+     ⇒This is the first and last normal input line.
+     ^D
+     ⇒This is the cleanup action.
+
+   The saved input is only reread when the end of normal input is seen,
+and not if ‘m4exit’ is used to exit ‘m4’.
+
+   It is safe to call ‘m4wrap’ from saved text, but then the order in
+which the saved text is reread is undefined.  If ‘m4wrap’ is not used
+recursively, the saved pieces of text are reread in the opposite order
+in which they were saved (LIFO—last in, first out).  However, this
+behavior is likely to change in a future release, to match POSIX, so you
+should not depend on this order.
+
+   It is possible to emulate POSIX behavior even with older versions of
+GNU M4 by including the file ‘m4-1.4.19/examples/wrapfifo.m4’ from the
+distribution:
+
+     $ m4 -I examples
+     undivert(`wrapfifo.m4')dnl
+     ⇒dnl Redefine m4wrap to have FIFO semantics.
+     ⇒define(`_m4wrap_level', `0')dnl
+     ⇒define(`m4wrap',
+     ⇒`ifdef(`m4wrap'_m4wrap_level,
+     ⇒       `define(`m4wrap'_m4wrap_level,
+     ⇒               defn(`m4wrap'_m4wrap_level)`$1')',
+     ⇒       `builtin(`m4wrap', `define(`_m4wrap_level',
+     ⇒                                  incr(_m4wrap_level))dnl
+     ⇒m4wrap'_m4wrap_level)dnl
+     ⇒define(`m4wrap'_m4wrap_level, `$1')')')dnl
+     include(`wrapfifo.m4')
+     ⇒
+     m4wrap(`a`'m4wrap(`c
+     ', `d')')m4wrap(`b')
+     ⇒
+     ^D
+     ⇒abc
+
+   It is likewise possible to emulate LIFO behavior without resorting to
+the GNU M4 extension of ‘builtin’, by including the file
+‘m4-1.4.19/examples/wraplifo.m4’ from the distribution.  (Unfortunately,
+both examples shown here share some subtle bugs.  See if you can find
+and correct them; or *note Answers: Improved m4wrap.).
+
+     $ m4 -I examples
+     undivert(`wraplifo.m4')dnl
+     ⇒dnl Redefine m4wrap to have LIFO semantics.

+     ⇒       `_m4wrap(`define(`_m4wrap_level', incr(_m4wrap_level))dnl
+     ⇒m4wrap'_m4wrap_level)dnl
+     ⇒define(`m4wrap'_m4wrap_level, `$1')')')dnl
+     include(`wraplifo.m4')
+     ⇒
+     m4wrap(`a`'m4wrap(`c
+     ', `d')')m4wrap(`b')
+     ⇒
+     ^D
+     ⇒bac
+
+   Here is an example of implementing a factorial function using
+‘m4wrap’:
+
+     define(`f', `ifelse(`$1', `0', `Answer: 0!=1
+     ', eval(`$1>1'), `0', `Answer: $2$1=eval(`$2$1')
+     ', `m4wrap(`f(decr(`$1'), `$2$1*')')')')
+     ⇒
+     f(`10')
+     ⇒
+     ^D
+     ⇒Answer: 10*9*8*7*6*5*4*3*2*1=3628800
+
+   Invocations of ‘m4wrap’ at the same recursion level are concatenated
+and rescanned as usual:
+
+     define(`aa', `AA
+     ')
+     ⇒
+     m4wrap(`a')m4wrap(`a')
+     ⇒
+     ^D
+     ⇒AA
+
+however, the transition between recursion levels behaves like an end of
+file condition between two input files.

+9 File inclusion
+****************
+
+‘m4’ allows you to include named files at any point in the input.
+
+* Menu:
+
+* Include::                     Including named files
+* Search Path::                 Searching for include files
+
+&#x1f;
+File: m4.info,  Node: Include,  Next: Search Path,  Up: File Inclusion
+
+9.1 Including named files
+=========================
+
+There are two builtin macros in ‘m4’ for including files:
+
+ -- Builtin: include (FILE)
+ -- Builtin: sinclude (FILE)
+     Both macros cause the file named FILE to be read by ‘m4’.  When the
+     end of the file is reached, input is resumed from the previous
+     input file.
+
+     The expansion of ‘include’ and ‘sinclude’ is therefore the contents
+     of FILE.
+
+     If FILE does not exist, is a directory, or cannot otherwise be
+     read, the expansion is void, and ‘include’ will fail with an error
+     while ‘sinclude’ is silent.  The empty string counts as a file that
+     does not exist.
+
+     The macros ‘include’ and ‘sinclude’ are recognized only with
+     parameters.
+
+     include(`none')
+     error→m4:stdin:1: cannot open `none': No such file or directory
+     ⇒
+     include()
+     error→m4:stdin:2: cannot open `': No such file or directory
+     ⇒
+     sinclude(`none')
+     ⇒
+     sinclude()
+     ⇒
+
+   The rest of this section assumes that ‘m4’ is invoked with the ‘-I’
+option (*note Invoking m4: Preprocessor features.) pointing to the
+‘m4-1.4.19/examples’ directory shipped as part of the GNU ‘m4’ package.
+The file ‘m4-1.4.19/examples/incl.m4’ in the distribution contains the
+lines:
+
+     $ cat examples/incl.m4
+     ⇒Include file start
+     ⇒foo
+     ⇒Include file end
+
+   Normally file inclusion is used to insert the contents of a file into
+the input stream.  The contents of the file will be read by ‘m4’ and
+macro calls in the file will be expanded:
+
+     $ m4 -I examples
+     define(`foo', `FOO')
+     ⇒
+     include(`incl.m4')
+     ⇒Include file start
+     ⇒FOO
+     ⇒Include file end
+     ⇒
+
+   The fact that ‘include’ and ‘sinclude’ expand to the contents of the
+file can be used to define macros that operate on entire files.  Here is
+an example, which defines ‘bar’ to expand to the contents of ‘incl.m4’:
+
+     $ m4 -I examples
+     define(`bar', include(`incl.m4'))
+     ⇒
+     This is `bar':  >>bar<<
+     ⇒This is bar:  >>Include file start
+     ⇒foo
+     ⇒Include file end
+     ⇒<<
+
+   This use of ‘include’ is not trivial, though, as files can contain
+quotes, commas, and parentheses, which can interfere with the way the
+‘m4’ parser works.  GNU ‘m4’ seamlessly concatenates the file contents
+with the next character, even if the included file ended in the middle
+of a comment, string, or macro call.  These conditions are only treated
+as end of file errors if specified as input files on the command line.
+
+   In GNU ‘m4’, an alternative method of reading files is using
+‘undivert’ (*note Undivert::) on a named file.
+
+&#x1f;
+File: m4.info,  Node: Search Path,  Prev: Include,  Up: File Inclusion
+
+9.2 Searching for include files
+===============================
+
+GNU ‘m4’ allows included files to be found in other directories than the
+current working directory.
+
+   If the ‘--prepend-include’ or ‘-B’ command-line option was provided
+(*note Invoking m4: Preprocessor features.), those directories are
+searched first, in reverse order that those options were listed on the
+command line.  Then ‘m4’ looks in the current working directory.  Next
+comes the directories specified with the ‘--include’ or ‘-I’ option, in
+the order found on the command line.  Finally, if the ‘M4PATH’
+environment variable is set, it is expected to contain a colon-separated
+list of directories, which will be searched in order.
+
+   If the automatic search for include-files causes trouble, the ‘p’
+debug flag (*note Debug Levels::) can help isolate the problem.

+
+10 Diverting and undiverting output
+***********************************
+
+Diversions are a way of temporarily saving output.  The output of ‘m4’
+can at any time be diverted to a temporary file, and be reinserted into
+the output stream, “undiverted”, again at a later time.
+
+   Numbered diversions are counted from 0 upwards, diversion number 0
+being the normal output stream.  GNU ‘m4’ tries to keep diversions in
+memory.  However, there is a limit to the overall memory usable by all
+diversions taken together (512K, currently).  When this maximum is about
+to be exceeded, a temporary file is opened to receive the contents of
+the biggest diversion still in memory, freeing this memory for other
+diversions.  When creating the temporary file, ‘m4’ honors the value of
+the environment variable ‘TMPDIR’, and falls back to ‘/tmp’.  Thus, the
+amount of available disk space provides the only real limit on the
+number and aggregate size of diversions.
+
+   Diversions make it possible to generate output in a different order
+than the input was read.  It is possible to implement topological
+sorting dependencies.  For example, GNU Autoconf makes use of diversions
+under the hood to ensure that the expansion of a prerequisite macro
+appears in the output prior to the expansion of a dependent macro,
+regardless of which order the two macros were invoked in the user’s
+input file.

+
+10.1 Diverting output
+=====================
+
+Output is diverted using ‘divert’:
+
+ -- Builtin: divert (NUMBER = ‘0’)
+     The current diversion is changed to NUMBER.  If NUMBER is left out
+     or empty, it is assumed to be zero.  If NUMBER cannot be parsed,
+     the diversion is unchanged.
+
+     The expansion of ‘divert’ is void.
+
+   When all the ‘m4’ input will have been processed, all existing
+diversions are automatically undiverted, in numerical order.
+
+     divert(`1')
+     This text is diverted.
+     divert
+     ⇒
+     This text is not diverted.
+     ⇒This text is not diverted.
+     ^D
+     ⇒
+     ⇒This text is diverted.
+
+   Several calls of ‘divert’ with the same argument do not overwrite the
+previous diverted text, but append to it.  Diversions are printed after
+any wrapped text is expanded.
+
+     define(`text', `TEXT')
+     ⇒
+     divert(`1')`diverted text.'
+     divert
+     ⇒
+     m4wrap(`Wrapped text precedes ')
+     ⇒
+     ^D
+     ⇒Wrapped TEXT precedes diverted text.
+
+   If output is diverted to a negative diversion, it is simply
+discarded.  This can be used to suppress unwanted output.  A common
+example of unwanted output is the trailing newlines after macro
+definitions.  Here is a common programming idiom in ‘m4’ for avoiding
+them.
+
+     divert(`-1')
+     define(`foo', `Macro `foo'.')
+     define(`bar', `Macro `bar'.')
+     divert
+     ⇒
+
+   Traditional implementations only supported ten diversions.  But as a
+GNU extension, diversion numbers can be as large as positive integers
+will allow, rather than treating a multi-digit diversion number as a
+request to discard text.
+
+     divert(eval(`1<<28'))world
+     divert(`2')hello
+     ^D
+     ⇒hello
+     ⇒world
+
+   Note that ‘divert’ is an English word, but also an active macro
+without arguments.  When processing plain text, the word might appear in
+normal text and be unintentionally swallowed as a macro invocation.  One
+way to avoid this is to use the ‘-P’ option to rename all builtins
+(*note Invoking m4: Operation modes.).  Another is to write a wrapper
+that requires a parameter to be recognized.
+
+     We decided to divert the stream for irrigation.
+     ⇒We decided to  the stream for irrigation.
+     define(`divert', `ifelse(`$#', `0', ``$0'', `builtin(`$0', $@)')')

+
+10.2 Undiverting output
+=======================
+
+Diverted text can be undiverted explicitly using the builtin ‘undivert’:
+
+ -- Builtin: undivert (DIVERSIONS...)
+     Undiverts the numeric DIVERSIONS given by the arguments, in the
+     order given.  If no arguments are supplied, all diversions are
+     undiverted, in numerical order.
+
+     As a GNU extension, DIVERSIONS may contain non-numeric strings,
+     which are treated as the names of files to copy into the output
+     without expansion.  A warning is issued if a file could not be
+     opened.
+
+     The expansion of ‘undivert’ is void.
+
+     divert(`1')
+     This text is diverted.
+     divert
+     ⇒
+     This text is not diverted.
+     ⇒This text is not diverted.
+     undivert(`1')
+     ⇒
+     ⇒This text is diverted.
+     ⇒
+
+   Notice the last two blank lines.  One of them comes from the newline
+following ‘undivert’, the other from the newline that followed the
+‘divert’!  A diversion often starts with a blank line like this.
+
+   When diverted text is undiverted, it is _not_ reread by ‘m4’, but
+rather copied directly to the current output, and it is therefore not an
+error to undivert into a diversion.  Undiverting the empty string is the
+same as specifying diversion 0; in either case nothing happens since the
+output has already been flushed.
+
+     divert(`1')diverted text
+     divert
+     ⇒
+     undivert()
+     ⇒
+     undivert(`0')
+     ⇒

+     ⇒diverted text
+     ⇒
+     divert(`1')more
+     divert(`2')undivert(`1')diverted text`'divert
+     ⇒
+     undivert(`1')
+     ⇒
+     undivert(`2')
+     ⇒more
+     ⇒diverted text
+
+   When a diversion has been undiverted, the diverted text is discarded,
+and it is not possible to bring back diverted text more than once.
+
+     divert(`1')
+     This text is diverted first.
+     divert(`0')undivert(`1')dnl
+     ⇒
+     ⇒This text is diverted first.
+     undivert(`1')
+     ⇒
+     divert(`1')
+     This text is also diverted but not appended.
+     divert(`0')undivert(`1')dnl
+     ⇒
+     ⇒This text is also diverted but not appended.
+
+   Attempts to undivert the current diversion are silently ignored.
+Thus, when the current diversion is not 0, the current diversion does
+not get rearranged among the other diversions.
+
+     divert(`1')one
+     divert(`2')two
+     divert(`3')three
+     divert(`2')undivert`'dnl
+     divert`'undivert`'dnl
+     ⇒two
+     ⇒one
+     ⇒three
+
+   GNU ‘m4’ allows named files to be undiverted.  Given a non-numeric
+argument, the contents of the file named will be copied, uninterpreted,
+to the current output.  This complements the builtin ‘include’ (*note
+Include::).  To illustrate the difference, assume the file ‘foo’
+contains:
+
+     $ cat foo
+     bar
+
+then
+
+     define(`bar', `BAR')
+     ⇒
+     undivert(`foo')
+     ⇒bar
+     ⇒
+     include(`foo')
+     ⇒BAR
+     ⇒
+
+   If the file is not found (or cannot be read), an error message is
+issued, and the expansion is void.  It is possible to intermix files and
+diversion numbers.

+     divert(`1')diversion one

+10.3 Diversion numbers
+======================
+
+The current diversion is tracked by the builtin ‘divnum’:
+
+ -- Builtin: divnum
+     Expands to the number of the current diversion.
+
+     Initial divnum
+     ⇒Initial 0
+     divert(`1')
+     Diversion one: divnum
+     divert(`2')
+     Diversion two: divnum

+
+&#x1f;
+File: m4.info,  Node: Cleardivert,  Prev: Divnum,  Up: Diversions
+
+10.4 Discarding diverted text
+=============================
+
+Often it is not known, when output is diverted, whether the diverted
+text is actually needed.  Since all non-empty diversion are brought back
+on the main output stream when the end of input is seen, a method of
+discarding a diversion is needed.  If all diversions should be
+discarded, the easiest is to end the input to ‘m4’ with ‘divert(`-1')’
+followed by an explicit ‘undivert’:
+
+     divert(`1')
+     Diversion one: divnum
+     divert(`2')
+     Diversion two: divnum
+     divert(`-1')
+     undivert
+     ^D
+
+No output is produced at all.
+
+   Clearing selected diversions can be done with the following macro:
+
+ -- Composite: cleardivert (DIVERSIONS...)
+     Discard the contents of each of the listed numeric DIVERSIONS.
+
+     define(`cleardivert',
+     `pushdef(`_n', divnum)divert(`-1')undivert($@)divert(_n)popdef(`_n')')
+     ⇒
+
+   It is called just like ‘undivert’, but the effect is to clear the
+diversions, given by the arguments.  (This macro has a nasty bug!  You
+should try to see if you can find it and correct it; or *note Answers:
+Improved cleardivert.).

+11.1 Calculating length of strings
+==================================
+
+The length of a string can be calculated by ‘len’:
+
+ -- Builtin: len (STRING)
+     Expands to the length of STRING, as a decimal number.
+
+     The macro ‘len’ is recognized only with parameters.
+
+     len()
+     ⇒0
+     len(`abcdef')
+     ⇒6

+
+11.2 Searching for substrings
+=============================
+
+Searching for substrings is done with ‘index’:
+
+ -- Builtin: index (STRING, SUBSTRING)
+     Expands to the index of the first occurrence of SUBSTRING in
+     STRING.  The first character in STRING has index 0.  If SUBSTRING
+     does not occur in STRING, ‘index’ expands to ‘-1’.
+
+     The macro ‘index’ is recognized only with parameters.
+
+     index(`gnus, gnats, and armadillos', `nat')
+     ⇒7
+     index(`gnus, gnats, and armadillos', `dag')
+     ⇒-1
+
+   Omitting SUBSTRING evokes a warning, but still produces output;
+contrast this with an empty SUBSTRING.
+
+     index(`abc')
+     error→m4:stdin:1: Warning: too few arguments to builtin `index'
+     ⇒0

+
+11.3 Searching for regular expressions
+======================================
+
+Searching for regular expressions is done with the builtin ‘regexp’:
+
+ -- Builtin: regexp (STRING, REGEXP, REPLACEMENT)
+     Searches for REGEXP in STRING.  The syntax for regular expressions
+     is the same as in GNU Emacs, which is similar to BRE, Basic Regular
+     Expressions in POSIX. *Note Syntax of Regular Expressions:
+     (emacs)Regexps.  Support for ERE, Extended Regular Expressions is
+     not available, but will be added in GNU M4 2.0.
+
+     If REPLACEMENT is omitted, ‘regexp’ expands to the index of the
+     first match of REGEXP in STRING.  If REGEXP does not match anywhere
+     in STRING, it expands to -1.
+
+     If REPLACEMENT is supplied, and there was a match, ‘regexp’ changes
+     the expansion to this argument, with ‘\N’ substituted by the text
+     matched by the Nth parenthesized sub-expression of REGEXP, up to
+     nine sub-expressions.  The escape ‘\&’ is replaced by the text of
+     the entire regular expression matched.  For all other characters,
+     ‘\’ treats the next character literally.  A warning is issued if
+     there were fewer sub-expressions than the ‘\N’ requested, or if
+     there is a trailing ‘\’.  If there was no match, ‘regexp’ expands
+     to the empty string.
+
+     The macro ‘regexp’ is recognized only with parameters.
+
+     regexp(`GNUs not Unix', `\<a-z\w+')
+     ⇒5
+     regexp(`GNUs not Unix', `\<Q\w*')
+     ⇒-1
+     regexp(`GNUs not Unix', `\w$\w+$$', `*** \& *** \1 ***')
+     ⇒*** Unix *** nix ***
+     regexp(`GNUs not Unix', `\<Q\w*', `*** \& *** \1 ***')
+     ⇒
+
+   Here are some more examples on the handling of backslash:
+
+     regexp(`abc', `$b$', `\\\10\a')
+     ⇒\b0a
+     regexp(`abc', `b', `\1\')
+     error→m4:stdin:2: Warning: sub-expression 1 not present
+     error→m4:stdin:2: Warning: trailing \ ignored in replacement
+     ⇒
+     regexp(`abc', `$\(d$?\)$c$', `\1\2\3\4\5\6')
+     error→m4:stdin:3: Warning: sub-expression 4 not present
+     error→m4:stdin:3: Warning: sub-expression 5 not present
+     error→m4:stdin:3: Warning: sub-expression 6 not present
+     ⇒c
+
+   Omitting REGEXP evokes a warning, but still produces output; contrast
+this with an empty REGEXP argument.
+
+     regexp(`abc')
+     error→m4:stdin:1: Warning: too few arguments to builtin `regexp'
+     ⇒0
+     regexp(`abc', `')

+File: m4.info,  Node: Substr,  Next: Translit,  Prev: Regexp,  Up: Text handling
+
+11.4 Extracting substrings
+==========================
+
+Substrings are extracted with ‘substr’:
+
+ -- Builtin: substr (STRING, FROM, LENGTH)
+     Expands to the substring of STRING, which starts at index FROM, and
+     extends for LENGTH characters, or to the end of STRING, if LENGTH
+     is omitted.  The starting index of a string is always 0.  The
+     expansion is empty if there is an error parsing FROM or LENGTH, if
+     FROM is beyond the end of STRING, or if LENGTH is negative.
+
+     The macro ‘substr’ is recognized only with parameters.
+
+     substr(`gnus, gnats, and armadillos', `6')
+     ⇒gnats, and armadillos
+     substr(`gnus, gnats, and armadillos', `6', `5')
+     ⇒gnats
+
+   Omitting FROM evokes a warning, but still produces output.
+
+     substr(`abc')
+     error→m4:stdin:1: Warning: too few arguments to builtin `substr'
+     ⇒abc
+     substr(`abc',)
+     error→m4:stdin:2: empty string treated as 0 in builtin `substr'
+     ⇒abc
+
+&#x1f;
+File: m4.info,  Node: Translit,  Next: Patsubst,  Prev: Substr,  Up: Text handling
+
+11.5 Translating characters
+===========================
+
+Character translation is done with ‘translit’:
+
+ -- Builtin: translit (STRING, CHARS, REPLACEMENT)
+     Expands to STRING, with each character that occurs in CHARS
+     translated into the character from REPLACEMENT with the same index.
+
+     If REPLACEMENT is shorter than CHARS, the excess characters of
+     CHARS are deleted from the expansion; if CHARS is shorter, the
+     excess characters in REPLACEMENT are silently ignored.  If
+     REPLACEMENT is omitted, all characters in STRING that are present
+     in CHARS are deleted from the expansion.  If a character appears
+     more than once in CHARS, only the first instance is used in making
+     the translation.  Only a single translation pass is made, even if
+     characters in REPLACEMENT also appear in CHARS.
+
+     As a GNU extension, both CHARS and REPLACEMENT can contain
+     character-ranges, e.g., ‘a-z’ (meaning all lowercase letters) or
+     ‘0-9’ (meaning all digits).  To include a dash ‘-’ in CHARS or
+     REPLACEMENT, place it first or last in the entire string, or as the
+     last character of a range.  Back-to-back ranges can share a common
+     endpoint.  It is not an error for the last character in the range
+     to be ‘larger’ than the first.  In that case, the range runs
+     backwards, i.e., ‘9-0’ means the string ‘9876543210’.  The
+     expansion of a range is dependent on the underlying encoding of
+     characters, so using ranges is not always portable between
+     machines.
+
+     The macro ‘translit’ is recognized only with parameters.
+
+     translit(`GNUs not Unix', `A-Z')
+     ⇒s not nix
+     translit(`GNUs not Unix', `a-z', `A-Z')
+     ⇒GNUS NOT UNIX
+     translit(`GNUs not Unix', `A-Z', `z-a')
+     ⇒tmfs not fnix
+     translit(`+,-12345', `+--1-5', `<;>a-c-a')
+     ⇒<;>abcba
+     translit(`abcdef', `aabdef', `bcged')
+     ⇒bgced
+
+   In the ASCII encoding, the first example deletes all uppercase
+letters, the second converts lowercase to uppercase, and the third
+‘mirrors’ all uppercase letters, while converting them to lowercase.
+The two first cases are by far the most common, even though they are not
+portable to EBCDIC or other encodings.  The fourth example shows a range
+ending in ‘-’, as well as back-to-back ranges.  The final example shows
+that ‘a’ is mapped to ‘b’, not ‘c’; the resulting ‘b’ is not further
+remapped to ‘g’; the ‘d’ and ‘e’ are swapped, and the ‘f’ is discarded.
+
+   Omitting CHARS evokes a warning, but still produces output.
+
+     translit(`abc')
+     error→m4:stdin:1: Warning: too few arguments to builtin `translit'
+     ⇒abc
+
+&#x1f;
+File: m4.info,  Node: Patsubst,  Next: Format,  Prev: Translit,  Up: Text handling
+
+11.6 Substituting text by regular expression
+============================================
+
+Global substitution in a string is done by ‘patsubst’:
+
+ -- Builtin: patsubst (STRING, REGEXP, REPLACEMENT)
+     Searches STRING for matches of REGEXP, and substitutes REPLACEMENT
+     for each match.  The syntax for regular expressions is the same as
+     in GNU Emacs (*note Regexp::).
+
+     The parts of STRING that are not covered by any match of REGEXP are
+     copied to the expansion.  Whenever a match is found, the search
+     proceeds from the end of the match, so a character from STRING will
+     never be substituted twice.  If REGEXP matches a string of zero
+     length, the start position for the search is incremented, to avoid
+     infinite loops.
+
+     When a replacement is to be made, REPLACEMENT is inserted into the
+     expansion, with ‘\N’ substituted by the text matched by the Nth
+     parenthesized sub-expression of PATSUBST, for up to nine
+     sub-expressions.  The escape ‘\&’ is replaced by the text of the
+     entire regular expression matched.  For all other characters, ‘\’
+     treats the next character literally.  A warning is issued if there
+     were fewer sub-expressions than the ‘\N’ requested, or if there is
+     a trailing ‘\’.
+
+     The REPLACEMENT argument can be omitted, in which case the text
+     matched by REGEXP is deleted.
+
+     The macro ‘patsubst’ is recognized only with parameters.
+
+     patsubst(`GNUs not Unix', `^', `OBS: ')
+     ⇒OBS: GNUs not Unix
+     patsubst(`GNUs not Unix', `\<', `OBS: ')
+     ⇒OBS: GNUs OBS: not OBS: Unix
+     patsubst(`GNUs not Unix', `\w*', `(\&)')
+     ⇒(GNUs)() (not)() (Unix)()
+     patsubst(`GNUs not Unix', `\w+', `(\&)')
+     ⇒(GNUs) (not) (Unix)
+     patsubst(`GNUs not Unix', `A-Za-z+')
+     ⇒GN not 
+     patsubst(`GNUs not Unix', `not', `NOT\')
+     error→m4:stdin:6: Warning: trailing \ ignored in replacement
+     ⇒GNUs NOT Unix
+
+   Here is a slightly more realistic example, which capitalizes
+individual words or whole sentences, by substituting calls of the macros
+‘upcase’ and ‘downcase’ into the strings.
+
+ -- Composite: upcase (TEXT)
+ -- Composite: downcase (TEXT)
+ -- Composite: capitalize (TEXT)
+     Expand to TEXT, but with capitalization changed: ‘upcase’ changes
+     all letters to upper case, ‘downcase’ changes all letters to lower
+     case, and ‘capitalize’ changes the first character of each word to
+     upper case and the remaining characters to lower case.
+
+   First, an example of their usage, using implementations distributed
+in ‘m4-1.4.19/examples/capitalize.m4’.
+
+     $ m4 -I examples
+     include(`capitalize.m4')
+     ⇒
+     upcase(`GNUs not Unix')
+     ⇒GNUS NOT UNIX
+     downcase(`GNUs not Unix')
+     ⇒gnus not unix
+     capitalize(`GNUs not Unix')
+     ⇒Gnus Not Unix
+
+   Now for the implementation.  There is a helper macro ‘_capitalize’
+which puts only its first word in mixed case.  Then ‘capitalize’ merely
+parses out the words, and replaces them with an invocation of
+‘_capitalize’.  (As presented here, the ‘capitalize’ macro has some
+subtle flaws.  You should try to see if you can find and correct them;
+or *note Answers: Improved capitalize.).
+
+     $ m4 -I examples
+     undivert(`capitalize.m4')dnl
+     ⇒divert(`-1')
+     ⇒# upcase(text)
+     ⇒# downcase(text)
+     ⇒# capitalize(text)
+     ⇒#   change case of text, simple version
+     ⇒define(`upcase', `translit(`$*', `a-z', `A-Z')')
+     ⇒define(`downcase', `translit(`$*', `A-Z', `a-z')')
+     ⇒define(`_capitalize',
+     ⇒       `regexp(`$1', `^$\w$$\w*$',
+     ⇒               `upcase(`\1')`'downcase(`\2')')')
+     ⇒define(`capitalize', `patsubst(`$1', `\w+', `_$0(`\&')')')
+     ⇒divert`'dnl
+
+   While ‘regexp’ replaces the whole input with the replacement as soon
+as there is a match, ‘patsubst’ replaces each _occurrence_ of a match
+and preserves non-matching pieces:
+
+     define(`patreg',
+     `patsubst($@)
+     regexp($@)')dnl
+     patreg(`bar foo baz Foo', `foo\|Foo', `FOO')
+     ⇒bar FOO baz FOO
+     ⇒FOO
+     patreg(`aba abb 121', `$.$$.$\1', `\2\1\2')
+     ⇒bab abb 212
+     ⇒bab
+
+   Omitting REGEXP evokes a warning, but still produces output; contrast
+this with an empty REGEXP argument.
+
+     patsubst(`abc')
+     error→m4:stdin:1: Warning: too few arguments to builtin `patsubst'
+     ⇒abc
+     patsubst(`abc', `')
+     ⇒abc
+     patsubst(`abc', `', `\\-')
+     ⇒\-a\-b\-c\-
+
+&#x1f;
+File: m4.info,  Node: Format,  Prev: Patsubst,  Up: Text handling
+
+11.7 Formatting strings (printf-like)
+=====================================
+
+Formatted output can be made with ‘format’:
+
+ -- Builtin: format (FORMAT-STRING, ...)
+     Works much like the C function ‘printf’.  The first argument
+     FORMAT-STRING can contain ‘%’ specifications which are satisfied by
+     additional arguments, and the expansion of ‘format’ is the
+     formatted string.
+
+     The macro ‘format’ is recognized only with parameters.
+
+   Its use is best described by a few examples:
+
+     define(`foo', `The brown fox jumped over the lazy dog')
+     ⇒
+     format(`The string "%s" uses %d characters', foo, len(foo))
+     ⇒The string "The brown fox jumped over the lazy dog" uses 38 characters
+     format(`%*.*d', `-1', `-1', `1')
+     ⇒1
+     format(`%.0f', `56789.9876')
+     ⇒56790
+     len(format(`%-*X', `5000', `1'))
+     ⇒5000
+     ifelse(format(`%010F', `infinity'), `       INF', `success',
+            format(`%010F', `infinity'), `  INFINITY', `success',
+            format(`%010F', `infinity'))
+     ⇒success
+     ifelse(format(`%.1A', `1.999'), `0X1.0P+1', `success',
+            format(`%.1A', `1.999'), `0X2.0P+0', `success',
+            format(`%.1A', `1.999'))
+     ⇒success
+     format(`%g', `0xa.P+1')
+     ⇒20
+
+   Using the ‘forloop’ macro defined earlier (*note Forloop::), this
+example shows how ‘format’ can be used to produce tabular output.
+
+     $ m4 -I examples
+     include(`forloop.m4')
+     ⇒
+     forloop(`i', `1', `10', `format(`%6d squared is %10d
+     ', i, eval(i**2))')
+     ⇒     1 squared is          1
+     ⇒     2 squared is          4
+     ⇒     3 squared is          9
+     ⇒     4 squared is         16
+     ⇒     5 squared is         25
+     ⇒     6 squared is         36
+     ⇒     7 squared is         49
+     ⇒     8 squared is         64
+     ⇒     9 squared is         81
+     ⇒    10 squared is        100
+     ⇒
+
+   The builtin ‘format’ is modeled after the ANSI C ‘printf’ function,
+and supports these ‘%’ specifiers: ‘c’, ‘s’, ‘d’, ‘o’, ‘x’, ‘X’, ‘u’,
+‘a’, ‘A’, ‘e’, ‘E’, ‘f’, ‘F’, ‘g’, ‘G’, and ‘%’; it supports field
+widths and precisions, and the flags ‘+’, ‘-’, ‘ ’, ‘0’, ‘#’, and ‘'’.
+For integer specifiers, the width modifiers ‘hh’, ‘h’, and ‘l’ are
+recognized, and for floating point specifiers, the width modifier ‘l’ is
+recognized.  Items not yet supported include positional arguments, the
+‘n’, ‘p’, ‘S’, and ‘C’ specifiers, the ‘z’, ‘t’, ‘j’, ‘L’ and ‘ll’
+modifiers, and any platform extensions available in the native ‘printf’.
+For more details on the functioning of ‘printf’, see the C Library
+Manual, or the POSIX specification (for example, ‘%a’ is supported even
+on platforms that haven’t yet implemented C99 hexadecimal floating point
+output natively).
+
+   Unrecognized specifiers result in a warning.  It is anticipated that
+a future release of GNU ‘m4’ will support more specifiers, and give
+better warnings when various problems such as overflow are encountered.
+Likewise, escape sequences are not yet recognized.

+     Expand to the numerical value of NUMBER, incremented or

+
+12.2 Evaluating integer expressions
+===================================
+
+Integer expressions are evaluated with ‘eval’:
+
+ -- Builtin: eval (EXPRESSION, RADIX = ‘10’, WIDTH)
+     Expands to the value of EXPRESSION.  The expansion is empty if a
+     problem is encountered while parsing the arguments.  If specified,
+     RADIX and WIDTH control the format of the output.
+
+     Calculations are done with 32-bit signed numbers.  Overflow
+     silently results in wraparound.  A warning is issued if division by
+     zero is attempted, or if EXPRESSION could not be parsed.
+
+     Expressions can contain the following operators, listed in order of
+     decreasing precedence.
+
+     ‘()’
+          Parentheses
+     ‘+ - ~ !’
+          Unary plus and minus, and bitwise and logical negation
+     ‘**’
+          Exponentiation
+     ‘* / %’
+          Multiplication, division, and modulo
+     ‘+ -’
+          Addition and subtraction
+     ‘<< >>’
+          Shift left or right
+     ‘> >= < <=’
+          Relational operators
+     ‘== !=’
+          Equality operators
+     ‘&’
+          Bitwise and
+     ‘^’
+          Bitwise exclusive-or
+     ‘|’
+          Bitwise or
+     ‘&&’
+          Logical and
+     ‘||’
+          Logical or
+
+     The macro ‘eval’ is recognized only with parameters.
+
+   All binary operators, except exponentiation, are left associative.  C
+operators that perform variable assignment, such as ‘+=’ or ‘--’, are
+not implemented, since ‘eval’ only operates on constants, not variables.
+Attempting to use them results in an error.  However, since traditional
+implementations treated ‘=’ as an undocumented alias for ‘==’ as opposed
+to an assignment operator, this usage is supported as a special case.
+Be aware that a future version of GNU M4 may support assignment
+semantics as an extension when POSIX mode is not requested, and that
+using ‘=’ to check equality is not portable.
+
+     eval(`2 = 2')
+     error→m4:stdin:1: Warning: recommend ==, not =, for equality operator
+     ⇒1
+     eval(`++0')
+     error→m4:stdin:2: invalid operator in eval: ++0
+     ⇒
+     eval(`0 |= 1')
+     error→m4:stdin:3: invalid operator in eval: 0 |= 1
+     ⇒
+
+   Note that some older ‘m4’ implementations use ‘^’ as an alternate
+operator for the exponentiation, although POSIX requires the C behavior
+of bitwise exclusive-or.  The precedence of the negation operators, ‘~’
+and ‘!’, was traditionally lower than equality.  The unary operators
+could not be used reliably more than once on the same term without
+intervening parentheses.  The traditional precedence of the equality
+operators ‘==’ and ‘!=’ was identical instead of lower than the
+relational operators such as ‘<’, even through GNU M4 1.4.8.  Starting
+with version 1.4.9, GNU M4 correctly follows POSIX precedence rules.  M4
+scripts designed to be portable between releases must be aware that
+parentheses may be required to enforce C precedence rules.  Likewise,
+division by zero, even in the unused branch of a short-circuiting
+operator, is not always well-defined in other implementations.
+
+   Following are some examples where the current version of M4 follows C

+
+   As a GNU extension, the operator ‘**’ performs integral
+exponentiation.  The operator is right-associative, and if evaluated,
+the exponent must be non-negative, and at least one of the arguments
+must be non-zero, or a warning is issued.

+     ⇒
+
+   Within EXPRESSION, (but not RADIX or WIDTH), numbers without a
+special prefix are decimal.  A simple ‘0’ prefix introduces an octal
+number.  ‘0x’ introduces a hexadecimal number.  As GNU extensions, ‘0b’
+introduces a binary number.  ‘0r’ introduces a number expressed in any
+radix between 1 and 36: the prefix should be immediately followed by the
+decimal expression of the radix, a colon, then the digits making the
+number.  For radix 1, leading zeros are ignored, and all remaining
+digits must be ‘1’; for all other radices, the digits are ‘0’, ‘1’, ‘2’,
+....  Beyond ‘9’, the digits are ‘a’, ‘b’ ... up to ‘z’.  Lower and
+upper case letters can be used interchangeably in numbers prefixes and
+as number digits.
+
+   Parentheses may be used to group subexpressions whenever needed.  For
+the relational operators, a true relation returns ‘1’, and a false
+relation return ‘0’.
+
+   Here are a few examples of use of ‘eval’.
+
+     eval(`-3 * 5')
+     ⇒-15
+     eval(`-99 / 10')
+     ⇒-9
+     eval(`-99 % 10')
+     ⇒-9
+     eval(`99 % -10')
+     ⇒9
+     eval(index(`Hello world', `llo') >= 0)

+     error→m4:stdin:11: bad expression in eval: foo / 6
+     ⇒
+     eval(foo / 6)
+     ⇒111
+
+   As the last two lines show, ‘eval’ does not handle macro names, even
+if they expand to a valid expression (or part of a valid expression).
+Therefore all macros must be expanded before they are passed to ‘eval’.
+
+   Some calculations are not portable to other implementations, since
+they have undefined semantics in C, but GNU ‘m4’ has well-defined
+behavior on overflow.  When shifting, an out-of-range shift amount is
+implicitly brought into the range of 32-bit signed integers using an
+implicit bit-wise and with 0x1f).
+
+     define(`max_int', eval(`0x7fffffff'))
+     ⇒
+     define(`min_int', incr(max_int))

+     eval(`-4 >> 1')
+     ⇒-2
+     eval(`-4 >> 33')
+     ⇒-2
+
+   If RADIX is specified, it specifies the radix to be used in the
+expansion.  The default radix is 10; this is also the case if RADIX is
+the empty string.  A warning results if the radix is outside the range
+of 1 through 36, inclusive.  The result of ‘eval’ is always taken to be
+signed.  No radix prefix is output, and for radices greater than 10, the
+digits are lower case.  The WIDTH argument specifies the minimum output
+width, excluding any negative sign.  The result is zero-padded to extend
+the expansion to the requested width.  A warning results if the width is
+negative.  If RADIX or WIDTH is out of bounds, the expansion of ‘eval’
+is empty.

+13 Macros for running shell commands
+************************************
+
+There are a few builtin macros in ‘m4’ that allow you to run shell
+commands from within ‘m4’.
+
+   Note that the definition of a valid shell command is system
+dependent.  On UNIX systems, this is the typical ‘/bin/sh’.  But on
+other systems, such as native Windows, the shell has a different syntax
+of commands that it understands.  Some examples in this chapter assume
+‘/bin/sh’, and also demonstrate how to quit early with a known exit
+value if this is not the case.

+File: m4.info,  Node: Platform macros,  Next: Syscmd,  Up: Shell commands
+
+13.1 Determining the platform
+=============================
+
+Sometimes it is desirable for an input file to know which platform ‘m4’
+is running on.  GNU ‘m4’ provides several macros that are predefined to
+expand to the empty string; checking for their existence will confirm
+platform details.
+
+ -- Optional builtin: __gnu__
+ -- Optional builtin: __os2__
+ -- Optional builtin: os2
+ -- Optional builtin: __unix__
+ -- Optional builtin: unix
+ -- Optional builtin: __windows__
+ -- Optional builtin: windows
+     Each of these macros is conditionally defined as needed to describe
+     the environment of ‘m4’.  If defined, each macro expands to the
+     empty string.  For now, these macros silently ignore all arguments,
+     but in a future release of M4, they might warn if arguments are
+     present.
+
+   When GNU extensions are in effect (that is, when you did not use the
+‘-G’ option, *note Invoking m4: Limits control.), GNU ‘m4’ will define
+the macro ‘__gnu__’ to expand to the empty string.
+
+     $ m4
+     __gnu__
+     ⇒
+     __gnu__(`ignored')
+     ⇒
+     Extensions are ifdef(`__gnu__', `active', `inactive')
+     ⇒Extensions are active
+
+     $ m4 -G
+     __gnu__
+     ⇒__gnu__
+     __gnu__(`ignored')
+     ⇒__gnu__(ignored)
+     Extensions are ifdef(`__gnu__', `active', `inactive')
+     ⇒Extensions are inactive
+
+   On UNIX systems, GNU ‘m4’ will define ‘__unix__’ by default, or
+‘unix’ when the ‘-G’ option is specified.
+
+   On native Windows systems, GNU ‘m4’ will define ‘__windows__’ by
+default, or ‘windows’ when the ‘-G’ option is specified.
+
+   On OS/2 systems, GNU ‘m4’ will define ‘__os2__’ by default, or ‘os2’
+when the ‘-G’ option is specified.
+
+   If GNU ‘m4’ does not provide a platform macro for your system, please
+report that as a bug.
+
+     define(`provided', `0')
+     ⇒
+     ifdef(`__unix__', `define(`provided', incr(provided))')
+     ⇒
+     ifdef(`__windows__', `define(`provided', incr(provided))')
+     ⇒
+     ifdef(`__os2__', `define(`provided', incr(provided))')
+     ⇒
+     provided
+     ⇒1
+
+&#x1f;
+File: m4.info,  Node: Syscmd,  Next: Esyscmd,  Prev: Platform macros,  Up: Shell commands
+
+13.2 Executing simple commands
+==============================
+
+Any shell command can be executed, using ‘syscmd’:
+
+ -- Builtin: syscmd (SHELL-COMMAND)
+     Executes SHELL-COMMAND as a shell command.
+
+     The expansion of ‘syscmd’ is void, _not_ the output from
+     SHELL-COMMAND!  Output or error messages from SHELL-COMMAND are not
+     read by ‘m4’.  *Note Esyscmd::, if you need to process the command
+     output.
+
+     Prior to executing the command, ‘m4’ flushes its buffers.  The
+     default standard input, output and error of SHELL-COMMAND are the
+     same as those of ‘m4’.
+
+     By default, the SHELL-COMMAND will be used as the argument to the
+     ‘-c’ option of the ‘/bin/sh’ shell (or the version of ‘sh’
+     specified by ‘command -p getconf PATH’, if your system supports
+     that).  If you prefer a different shell, the ‘configure’ script can
+     be given the option ‘--with-syscmd-shell=LOCATION’ to set the
+     location of an alternative shell at GNU ‘m4’ installation; the
+     alternative shell must still support ‘-c’.
+
+     The macro ‘syscmd’ is recognized only with parameters.
+
+     define(`foo', `FOO')
+     ⇒
+     syscmd(`echo foo')
+     ⇒foo
+     ⇒
+
+   Note how the expansion of ‘syscmd’ keeps the trailing newline of the
+command, as well as using the newline that appeared after the macro.
+
+   The following is an example of SHELL-COMMAND using the same standard
+input as ‘m4’:
+
+     $ echo "m4wrap(\`syscmd(\`cat')')" | m4
+     ⇒
+
+   It tells ‘m4’ to read all of its input before executing the wrapped
+text, then hand a valid (albeit emptied) pipe as standard input for the
+‘cat’ subcommand.  Therefore, you should be careful when using standard
+input (either by specifying no files, or by passing ‘-’ as a file name
+on the command line, *note Invoking m4: Command line files.), and also
+invoking subcommands via ‘syscmd’ or ‘esyscmd’ that consume data from
+standard input.  When standard input is a seekable file, the subprocess
+will pick up with the next character not yet processed by ‘m4’; when it
+is a pipe or other non-seekable file, there is no guarantee how much
+data will already be buffered by ‘m4’ and thus unavailable to the child.
+
+&#x1f;
+File: m4.info,  Node: Esyscmd,  Next: Sysval,  Prev: Syscmd,  Up: Shell commands
+
+13.3 Reading the output of commands
+===================================
+
+If you want ‘m4’ to read the output of a shell command, use ‘esyscmd’:
+
+ -- Builtin: esyscmd (SHELL-COMMAND)
+     Expands to the standard output of the shell command SHELL-COMMAND.
+
+     Prior to executing the command, ‘m4’ flushes its buffers.  The
+     default standard input and standard error of SHELL-COMMAND are the
+     same as those of ‘m4’.  The error output of SHELL-COMMAND is not a
+     part of the expansion: it will appear along with the error output
+     of ‘m4’.
+
+     By default, the SHELL-COMMAND will be used as the argument to the
+     ‘-c’ option of the ‘/bin/sh’ shell (or the version of ‘sh’
+     specified by ‘command -p getconf PATH’, if your system supports
+     that).  If you prefer a different shell, the ‘configure’ script can
+     be given the option ‘--with-syscmd-shell=LOCATION’ to set the
+     location of an alternative shell at GNU ‘m4’ installation; the
+     alternative shell must still support ‘-c’.
+
+     The macro ‘esyscmd’ is recognized only with parameters.
+
+     define(`foo', `FOO')
+     ⇒
+     esyscmd(`echo foo')
+     ⇒FOO
+     ⇒
+
+   Note how the expansion of ‘esyscmd’ keeps the trailing newline of the
+command, as well as using the newline that appeared after the macro.
+
+   Just as with ‘syscmd’, care must be exercised when sharing standard
+input between ‘m4’ and the child process of ‘esyscmd’.
+
+&#x1f;
+File: m4.info,  Node: Sysval,  Next: Mkstemp,  Prev: Esyscmd,  Up: Shell commands
+
+13.4 Exit status
+================
+
+To see whether a shell command succeeded, use ‘sysval’:
+
+ -- Builtin: sysval
+     Expands to the exit status of the last shell command run with
+     ‘syscmd’ or ‘esyscmd’.  Expands to 0 if no command has been run
+     yet.
+
+     sysval
+     ⇒0
+     syscmd(`false')
+     ⇒
+     ifelse(sysval, `0', `zero', `non-zero')
+     ⇒non-zero
+     syscmd(`exit 2')
+     ⇒
+     sysval
+     ⇒2
+     syscmd(`true')
+     ⇒
+     sysval
+     ⇒0
+     esyscmd(`false')
+     ⇒
+     ifelse(sysval, `0', `zero', `non-zero')
+     ⇒non-zero
+     esyscmd(`echo dnl && exit 127')
+     ⇒
+     sysval
+     ⇒127
+     esyscmd(`true')
+     ⇒
+     sysval
+     ⇒0
+
+   ‘sysval’ results in 127 if there was a problem executing the command,
+for example, if the system-imposed argument length is exceeded, or if
+there were not enough resources to fork.  It is not possible to
+distinguish between failed execution and successful execution that had
+an exit status of 127, unless there was output from the child process.
+
+   On UNIX platforms, where it is possible to detect when command
+execution is terminated by a signal, rather than a normal exit, the
+result is the signal number shifted left by eight bits.
+
+     dnl This test assumes kill is a shell builtin, and that signals are
+     dnl recognizable.
+     ifdef(`__unix__', ,
+           `errprint(` skipping: syscmd does not have unix semantics

+     ⇒
+     syscmd(/bin/sh -c 'kill -9 $$'; st=$?; test $st = 137 || test $st = 265)

+     ⇒2304
+
+&#x1f;
+File: m4.info,  Node: Mkstemp,  Prev: Sysval,  Up: Shell commands
+
+13.5 Making temporary files
+===========================
+
+Commands specified to ‘syscmd’ or ‘esyscmd’ might need a temporary file,
+for output or for some other purpose.  There is a builtin macro,
+‘mkstemp’, for making a temporary file:
+
+ -- Builtin: mkstemp (TEMPLATE)
+ -- Builtin: maketemp (TEMPLATE)
+     Expands to the quoted name of a new, empty file, made from the
+     string TEMPLATE, which should end with the string ‘XXXXXX’.  The
+     six ‘X’ characters are then replaced with random characters
+     matching the regular expression ‘a-zA-Z0-9._-’, in order to make
+     the file name unique.  If fewer than six ‘X’ characters are found
+     at the end of ‘template’, the result will be longer than the
+     template.  The created file will have access permissions as if by
+     ‘chmod =rw,go=’, meaning that the current umask of the ‘m4’ process
+     is taken into account, and at most only the current user can read
+     and write the file.
+
+     The traditional behavior, standardized by POSIX, is that ‘maketemp’
+     merely replaces the trailing ‘X’ with the process id, without
+     creating a file or quoting the expansion, and without ensuring that
+     the resulting string is a unique file name.  In part, this means
+     that using the same TEMPLATE twice in the same input file will
+     result in the same expansion.  This behavior is a security hole, as
+     it is very easy for another process to guess the name that will be
+     generated, and thus interfere with a subsequent use of ‘syscmd’
+     trying to manipulate that file name.  Hence, POSIX has recommended
+     that all new implementations of ‘m4’ provide the secure ‘mkstemp’
+     builtin, and that users of ‘m4’ check for its existence.
+
+     The expansion is void and an error issued if a temporary file could
+     not be created.
+
+     The macros ‘mkstemp’ and ‘maketemp’ are recognized only with
+     parameters.
+
+   If you try this next example, you will most likely get different
+output for the two file names, since the replacement characters are
+randomly chosen:
+
+     $ m4
+     define(`tmp', `oops')
+     ⇒
+     maketemp(`/tmp/fooXXXXXX')
+     ⇒/tmp/fooa07346
+     ifdef(`mkstemp', `define(`maketemp', defn(`mkstemp'))',
+           `define(`mkstemp', defn(`maketemp'))dnl
+     errprint(`warning: potentially insecure maketemp implementation
+     ')')
+     ⇒
+     mkstemp(`doc')
+     ⇒docQv83Uw
+
+   Unless you use the ‘--traditional’ command line option (or ‘-G’,
+*note Invoking m4: Limits control.), the GNU version of ‘maketemp’ is
+secure.  This means that using the same template to multiple calls will
+generate multiple files.  However, we recommend that you use the new
+‘mkstemp’ macro, introduced in GNU M4 1.4.8, which is secure even in
+traditional mode.  Also, as of M4 1.4.11, the secure implementation
+quotes the resulting file name, so that you are guaranteed to know what
+file was created even if the random file name happens to match an
+existing macro.  Notice that this example is careful to use ‘defn’ to
+avoid unintended expansion of ‘foo’.
+
+     $ m4
+     define(`foo', `errprint(`oops')')
+     ⇒
+     syscmd(`rm -f foo-??????')sysval
+     ⇒0
+     define(`file1', maketemp(`foo-XXXXXX'))dnl
+     ifelse(esyscmd(`echo \` foo-?????? \''), ` foo-?????? ',
+            `no file', `created')
+     ⇒created
+     define(`file2', maketemp(`foo-XX'))dnl
+     define(`file3', mkstemp(`foo-XXXXXX'))dnl
+     ifelse(len(defn(`file1')), len(defn(`file2')),
+            `same length', `different')
+     ⇒same length
+     ifelse(defn(`file1'), defn(`file2'), `same', `different file')
+     ⇒different file
+     ifelse(defn(`file2'), defn(`file3'), `same', `different file')
+     ⇒different file
+     ifelse(defn(`file1'), defn(`file3'), `same', `different file')
+     ⇒different file
+     syscmd(`rm 'defn(`file1') defn(`file2') defn(`file3'))
+     ⇒
+     sysval
+     ⇒0

+14 Miscellaneous builtin macros

+
+This chapter describes various builtins, that do not really belong in
+any of the previous chapters.

+File: m4.info,  Node: Errprint,  Next: Location,  Up: Miscellaneous
+
+14.1 Printing error messages
+============================
+
+You can print error messages using ‘errprint’:
+
+ -- Builtin: errprint (MESSAGE, ...)
+     Prints MESSAGE and the rest of the arguments to standard error,
+     separated by spaces.  Standard error is used, regardless of the
+     ‘--debugfile’ option (*note Invoking m4: Debugging options.).
+
+     The expansion of ‘errprint’ is void.  The macro ‘errprint’ is
+     recognized only with parameters.
+
+     errprint(`Invalid arguments to forloop
+     ')
+     error→Invalid arguments to forloop
+     ⇒
+     errprint(`1')errprint(`2',`3
+     ')
+     error→12 3
+     ⇒
+
+   A trailing newline is _not_ printed automatically, so it should be
+supplied as part of the argument, as in the example.  Unfortunately, the
+exact output of ‘errprint’ is not very portable to other ‘m4’
+implementations: POSIX requires that all arguments be printed, but some
+implementations of ‘m4’ only print the first.  Furthermore, some BSD
+implementations always append a newline for each ‘errprint’ call,
+regardless of whether the last argument already had one, and POSIX is
+silent on whether this is acceptable.
+
+&#x1f;
+File: m4.info,  Node: Location,  Next: M4exit,  Prev: Errprint,  Up: Miscellaneous
+
+14.2 Printing current location
+==============================
+
+To make it possible to specify the location of an error, three utility
+builtins exist:
+
+ -- Builtin: __file__
+ -- Builtin: __line__
+ -- Builtin: __program__
+     Expand to the quoted name of the current input file, the current
+     input line number in that file, and the quoted name of the current
+     invocation of ‘m4’.
+
+     errprint(__program__:__file__:__line__: `input error
+     ')
+     error→m4:stdin:1: input error
+     ⇒
+
+   Line numbers start at 1 for each file.  If the file was found due to
+the ‘-I’ option or ‘M4PATH’ environment variable, that is reflected in
+the file name.  The syncline option (‘-s’, *note Invoking m4:
+Preprocessor features.), and the ‘f’ and ‘l’ flags of ‘debugmode’ (*note
+Debug Levels::), also use this notion of current file and line.
+Redefining the three location macros has no effect on syncline, debug,
+warning, or error message output.
+
+   This example reuses the file ‘incl.m4’ mentioned earlier (*note
+Include::):
+
+     $ m4 -I examples
+     define(`foo', ``$0' called at __file__:__line__')
+     ⇒
+     foo
+     ⇒foo called at stdin:2
+     include(`incl.m4')
+     ⇒Include file start
+     ⇒foo called at examples/incl.m4:2
+     ⇒Include file end
+     ⇒
+
+   The location of macros invoked during the rescanning of macro
+expansion text corresponds to the location in the file where the
+expansion was triggered, regardless of how many newline characters the
+expansion text contains.  As of GNU M4 1.4.8, the location of text
+wrapped with ‘m4wrap’ (*note M4wrap::) is the point at which the
+‘m4wrap’ was invoked.  Previous versions, however, behaved as though
+wrapped text came from line 0 of the file “”.
+
+     define(`echo', `$@')
+     ⇒
+     define(`foo', `echo(__line__
+     __line__)')
+     ⇒
+     echo(__line__
+     __line__)
+     ⇒4
+     ⇒5
+     m4wrap(`foo
+     ')
+     ⇒
+     foo(errprint(__line__
+     __line__
+     ))
+     error→8
+     error→9
+     ⇒8
+     ⇒8
+     __line__
+     ⇒11
+     m4wrap(`__line__
+     ')
+     ⇒
+     ^D
+     ⇒12
+     ⇒6
+     ⇒6
+
+   The ‘__program__’ macro behaves like ‘$0’ in shell terminology.  If
+you invoke ‘m4’ through an absolute path or a link with a different
+spelling, rather than by relying on a ‘PATH’ search for plain ‘m4’, it
+will affect how ‘__program__’ expands.  The intent is that you can use
+it to produce error messages with the same formatting that ‘m4’ produces
+internally.  It can also be used within ‘syscmd’ (*note Syscmd::) to
+pick the same version of ‘m4’ that is currently running, rather than
+whatever version of ‘m4’ happens to be first in ‘PATH’.  It was first
+introduced in GNU M4 1.4.6.

+
+14.3 Exiting from ‘m4’
+======================
+
+If you need to exit from ‘m4’ before the entire input has been read, you
+can use ‘m4exit’:
+
+ -- Builtin: m4exit (CODE = ‘0’)
+     Causes ‘m4’ to exit, with exit status CODE.  If CODE is left out,
+     the exit status is zero.  If CODE cannot be parsed, or is outside
+     the range of 0 to 255, the exit status is one.  No further input is
+     read, and all wrapped and diverted text is discarded.
+
+     m4wrap(`This text is lost due to `m4exit'.')
+     ⇒
+     divert(`1') So is this.
+     divert
+     ⇒
+     m4exit And this is never read.
+
+   A common use of this is to abort processing:
+
+ -- Composite: fatal_error (MESSAGE)
+     Abort processing with an error message and non-zero status.  Prefix
+     MESSAGE with details about where the error occurred, and print the
+     resulting string to standard error.
+
+     define(`fatal_error',
+            `errprint(__program__:__file__:__line__`: fatal error: $*
+     ')m4exit(`1')')
+     ⇒
+     fatal_error(`this is a BAD one, buster')
+     error→m4:stdin:4: fatal error: this is a BAD one, buster
+
+   After this macro call, ‘m4’ will exit with exit status 1.  This macro
+is only intended for error exits, since the normal exit procedures are
+not followed, i.e., diverted text is not undiverted, and saved text
+(*note M4wrap::) is not reread.  (This macro could be made more robust
+to earlier versions of ‘m4’.  You should try to see if you can find
+weaknesses and correct them; or *note Answers: Improved fatal_error.).
+
+   Note that it is still possible for the exit status to be different
+than what was requested by ‘m4exit’.  If ‘m4’ detects some other error,
+such as a write error on standard output, the exit status will be
+non-zero even if ‘m4exit’ requested zero.
+
+   If standard input is seekable, then the file will be positioned at
+the next unread character.  If it is a pipe or other non-seekable file,
+then there are no guarantees how much data ‘m4’ might have read into
+buffers, and thus discarded.

+15 Fast loading of frozen state
+*******************************
+
+Some bigger ‘m4’ applications may be built over a common base containing
+hundreds of definitions and other costly initializations.  Usually, the
+common base is kept in one or more declarative files, which files are
+listed on each ‘m4’ invocation prior to the user’s input file, or else
+each input file uses ‘include’.
+
+   Reading the common base of a big application, over and over again,
+may be time consuming.  GNU ‘m4’ offers some machinery to speed up the
+start of an application using lengthy common bases.

+
+&#x1f;
+File: m4.info,  Node: Using frozen files,  Next: Frozen file format,  Up: Frozen files
+
+15.1 Using frozen files
+=======================
+
+Suppose a user has a library of ‘m4’ initializations in ‘base.m4’, which
+is then used with multiple input files:
+
+     $ m4 base.m4 input1.m4
+     $ m4 base.m4 input2.m4
+     $ m4 base.m4 input3.m4
+
+   Rather than spending time parsing the fixed contents of ‘base.m4’
+every time, the user might rather execute:
+
+     $ m4 -F base.m4f base.m4
+
+once, and further execute, as often as needed:
+
+     $ m4 -R base.m4f input1.m4
+     $ m4 -R base.m4f input2.m4
+     $ m4 -R base.m4f input3.m4
+
+with the varying input.  The first call, containing the ‘-F’ option,
+only reads and executes file ‘base.m4’, defining various application
+macros and computing other initializations.  Once the input file
+‘base.m4’ has been completely processed, GNU ‘m4’ produces in ‘base.m4f’
+a “frozen” file, that is, a file which contains a kind of snapshot of
+the ‘m4’ internal state.
+
+   Later calls, containing the ‘-R’ option, are able to reload the
+internal state of ‘m4’, from ‘base.m4f’, _prior_ to reading any other
+input files.  This means instead of starting with a virgin copy of ‘m4’,
+input will be read after having effectively recovered the effect of a
+prior run.  In our example, the effect is the same as if file ‘base.m4’
+has been read anew.  However, this effect is achieved a lot faster.
+
+   Only one frozen file may be created or read in any one ‘m4’
+invocation.  It is not possible to recover two frozen files at once.
+However, frozen files may be updated incrementally, through using ‘-R’
+and ‘-F’ options simultaneously.  For example, if some care is taken,
+the command:
+
+     $ m4 file1.m4 file2.m4 file3.m4 file4.m4
+
+could be broken down in the following sequence, accumulating the same
+output:
+
+     $ m4 -F file1.m4f file1.m4
+     $ m4 -R file1.m4f -F file2.m4f file2.m4
+     $ m4 -R file2.m4f -F file3.m4f file3.m4
+     $ m4 -R file3.m4f file4.m4
+
+   Some care is necessary because not every effort has been made for
+this to work in all cases.  In particular, the trace attribute of macros
+is not handled, nor the current setting of ‘changeword’.  Currently,
+‘m4wrap’ and ‘sysval’ also have problems.  Also, interactions for some
+options of ‘m4’, being used in one call and not in the next, have not
+been fully analyzed yet.  On the other end, you may be confident that
+stacks of ‘pushdef’ definitions are handled correctly, as well as
+undefined or renamed builtins, and changed strings for quotes or
+comments.  And future releases of GNU M4 will improve on the utility of
+frozen files.
+
+   When an ‘m4’ run is to be frozen, the automatic undiversion which
+takes place at end of execution is inhibited.  Instead, all positively
+numbered diversions are saved into the frozen file.  The active
+diversion number is also transmitted.
+
+   A frozen file to be reloaded need not reside in the current
+directory.  It is looked up the same way as an ‘include’ file (*note
+Search Path::).
+
+   If the frozen file was generated with a newer version of ‘m4’, and
+contains directives that an older ‘m4’ cannot parse, attempting to load
+the frozen file with option ‘-R’ will cause ‘m4’ to exit with status 63
+to indicate version mismatch.
+
+&#x1f;
+File: m4.info,  Node: Frozen file format,  Prev: Using frozen files,  Up: Frozen files
+
+15.2 Frozen file format
+=======================
+
+Frozen files are sharable across architectures.  It is safe to write a
+frozen file on one machine and read it on another, given that the second
+machine uses the same or newer version of GNU ‘m4’.  It is conventional,
+but not required, to give a frozen file the suffix of ‘.m4f’.
+
+   These are simple (editable) text files, made up of directives, each
+starting with a capital letter and ending with a newline (<NL>).
+Wherever a directive is expected, the character ‘#’ introduces a comment
+line; empty lines are also ignored if they are not part of an embedded
+string.  In the following descriptions, each LEN refers to the length of
+the corresponding strings STR in the next line of input.  Numbers are
+always expressed in decimal.  There are no escape characters.  The
+directives are:
+
+‘C LEN1 , LEN2 <NL> STR1 STR2 <NL>’
+     Uses STR1 and STR2 as the begin-comment and end-comment strings.
+     If omitted, then ‘#’ and <NL> are the comment delimiters.
+
+‘D NUMBER, LEN <NL> STR <NL>’
+     Selects diversion NUMBER, making it current, then copy STR in the
+     current diversion.  NUMBER may be a negative number for a
+     non-existing diversion.  To merely specify an active selection, use
+     this command with an empty STR.  With 0 as the diversion NUMBER,
+     STR will be issued on standard output at reload time.  GNU ‘m4’
+     will not produce the ‘D’ directive with non-zero length for
+     diversion 0, but this can be done with manual edits.  This
+     directive may appear more than once for the same diversion, in
+     which case the diversion is the concatenation of the various uses.
+     If omitted, then diversion 0 is current.
+
+‘F LEN1 , LEN2 <NL> STR1 STR2 <NL>’
+     Defines, through ‘pushdef’, a definition for STR1 expanding to the
+     function whose builtin name is STR2.  If the builtin does not exist
+     (for example, if the frozen file was produced by a copy of ‘m4’
+     compiled with changeword support, but the version of ‘m4’ reloading
+     was compiled without it), the reload is silent, but any subsequent
+     use of the definition of STR1 will result in a warning.  This
+     directive may appear more than once for the same name, and its
+     order, along with ‘T’, is important.  If omitted, you will have no
+     access to any builtins.
+
+‘Q LEN1 , LEN2 <NL> STR1 STR2 <NL>’
+     Uses STR1 and STR2 as the begin-quote and end-quote strings.  If
+     omitted, then ‘`’ and ‘'’ are the quote delimiters.
+
+‘T LEN1 , LEN2 <NL> STR1 STR2 <NL>’
+     Defines, though ‘pushdef’, a definition for STR1 expanding to the
+     text given by STR2.  This directive may appear more than once for
+     the same name, and its order, along with ‘F’, is important.
+
+‘V NUMBER <NL>’
+     Confirms the format of the file.  ‘m4’ 1.4.19 only creates and
+     understands frozen files where NUMBER is 1.  This directive must be
+     the first non-comment in the file, and may not appear more than
+     once.

+16 Compatibility with other versions of ‘m4’
+********************************************
+
+This chapter describes the many of the differences between this
+implementation of ‘m4’, and of other implementations found under UNIX,
+such as System V Release 4, Solaris, and BSD flavors.  In particular, it
+lists the known differences and extensions to POSIX. However, the list
+is not necessarily comprehensive.
+
+   At the time of this writing, POSIX 2001 (also known as IEEE Std
+1003.1-2001) is the latest standard, although a new version of POSIX is
+under development and includes several proposals for modifying what ‘m4’
+is required to do.  The requirements for ‘m4’ are shared between SUSv3
+and POSIX, and can be viewed at
+<https://www.opengroup.org/onlinepubs/000095399/utilities/m4.html>.

+
+&#x1f;
+File: m4.info,  Node: Extensions,  Next: Incompatibilities,  Up: Compatibility
+
+16.1 Extensions in GNU M4
+=========================
+
+This version of ‘m4’ contains a few facilities that do not exist in
+System V ‘m4’.  These extra facilities are all suppressed by using the
+‘-G’ command line option (*note Invoking m4: Limits control.), unless
+overridden by other command line options.
+
+   • In the ‘$N’ notation for macro arguments, N can contain several
+     digits, while the System V ‘m4’ only accepts one digit.  This
+     allows macros in GNU ‘m4’ to take any number of arguments, and not
+     only nine (*note Arguments::).
+
+     This means that ‘define(`foo', `$11')’ is ambiguous between
+     implementations.  To portably choose between grabbing the first
+     parameter and appending 1 to the expansion, or grabbing the
+     eleventh parameter, you can do the following:
+
+          define(`a1', `A1')
+          ⇒
+          dnl First argument, concatenated with 1
+          define(`_1', `$1')define(`first1', `_1($@)1')
+          ⇒
+          dnl Eleventh argument, portable
+          define(`_9', `$9')define(`eleventh', `_9(shift(shift($@)))')
+          ⇒
+          dnl Eleventh argument, GNU style
+          define(`Eleventh', `$11')
+          ⇒
+          first1(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k')
+          ⇒A1
+          eleventh(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k')
+          ⇒k
+          Eleventh(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k')
+          ⇒k
+
+     Also see the ‘argn’ macro (*note Shift::).
+
+   • The ‘divert’ (*note Divert::) macro can manage more than 9
+     diversions.  GNU ‘m4’ treats all positive numbers as valid
+     diversions, rather than discarding diversions greater than 9.
+
+   • Files included with ‘include’ and ‘sinclude’ are sought in a user
+     specified search path, if they are not found in the working
+     directory.  The search path is specified by the ‘-I’ option and the
+     ‘M4PATH’ environment variable (*note Search Path::).
+
+   • Arguments to ‘undivert’ can be non-numeric, in which case the named
+     file will be included uninterpreted in the output (*note
+     Undivert::).
+
+   • Formatted output is supported through the ‘format’ builtin, which
+     is modeled after the C library function ‘printf’ (*note Format::).
+
+   • Searches and text substitution through basic regular expressions
+     are supported by the ‘regexp’ (*note Regexp::) and ‘patsubst’
+     (*note Patsubst::) builtins.  Some BSD implementations use extended
+     regular expressions instead.
+
+   • The output of shell commands can be read into ‘m4’ with ‘esyscmd’
+     (*note Esyscmd::).
+
+   • There is indirect access to any builtin macro with ‘builtin’ (*note
+     Builtin::).
+
+   • Macros can be called indirectly through ‘indir’ (*note Indir::).
+
+   • The name of the program, the current input file, and the current
+     input line number are accessible through the builtins
+     ‘__program__’, ‘__file__’, and ‘__line__’ (*note Location::).
+
+   • The format of the output from ‘dumpdef’ and macro tracing can be
+     controlled with ‘debugmode’ (*note Debug Levels::).
+
+   • The destination of trace and debug output can be controlled with
+     ‘debugfile’ (*note Debug Output::).
+
+   • The ‘maketemp’ (*note Mkstemp::) macro behaves like ‘mkstemp’,
+     creating a new file with a unique name on every invocation, rather
+     than following the insecure behavior of replacing the trailing ‘X’
+     characters with the ‘m4’ process id.
+
+   • POSIX only requires support for the command line options ‘-s’,
+     ‘-D’, and ‘-U’, so all other options accepted by GNU M4 are
+     extensions.  *Note Invoking m4::, for a description of these
+     options.
+
+     The debugging and tracing facilities in GNU ‘m4’ are much more
+     extensive than in most other versions of ‘m4’.

+
+16.2 Facilities in System V ‘m4’ not in GNU ‘m4’
+================================================
+
+The version of ‘m4’ from System V contains a few facilities that have
+not been implemented in GNU ‘m4’ yet.  Additionally, POSIX requires some
+behaviors that GNU ‘m4’ has not implemented yet.  Relying on these
+behaviors is non-portable, as a future release of GNU ‘m4’ may change.
+
+   • POSIX requires support for multiple arguments to ‘defn’, without
+     any clarification on how ‘defn’ behaves when one of the multiple
+     arguments names a builtin.  System V ‘m4’ and some other
+     implementations allow mixing builtins and text macros into a single
+     macro.  GNU ‘m4’ only supports joining multiple text arguments,
+     although a future implementation may lift this restriction to
+     behave more like System V.  The only portable way to join text
+     macros with builtins is via helper macros and implicit
+     concatenation of macro results.
+
+   • POSIX requires an application to exit with non-zero status if it
+     wrote an error message to stderr.  This has not yet been
+     consistently implemented for the various builtins that are required
+     to issue an error (such as ‘eval’ (*note Eval::) when an argument
+     cannot be parsed).
+
+   • Some traditional implementations only allow reading standard input
+     once, but GNU ‘m4’ correctly handles multiple instances of ‘-’ on
+     the command line.
+
+   • POSIX requires ‘m4wrap’ (*note M4wrap::) to act in FIFO (first-in,
+     first-out) order, but GNU ‘m4’ currently uses LIFO order.
+     Furthermore, POSIX states that only the first argument to ‘m4wrap’
+     is saved for later evaluation, but GNU ‘m4’ saves and processes all
+     arguments, with output separated by spaces.
+
+   • POSIX states that builtins that require arguments, but are called
+     without arguments, have undefined behavior.  Traditional
+     implementations simply behave as though empty strings had been
+     passed.  For example, ‘a`'define`'b’ would expand to ‘ab’.  But GNU
+     ‘m4’ ignores certain builtins if they have missing arguments,
+     giving ‘adefineb’ for the above example.
+
+   • Traditional implementations handle ‘define(`f',`1')’ (*note
+     Define::) by undefining the entire stack of previous definitions,
+     and if doing ‘undefine(`f')’ first.  GNU ‘m4’ replaces just the top
+     definition on the stack, as if doing ‘popdef(`f')’ followed by
+     ‘pushdef(`f',`1')’.  POSIX allows either behavior.
+
+   • POSIX 2001 requires ‘syscmd’ (*note Syscmd::) to evaluate command
+     output for macro expansion, but this was a mistake that is
+     anticipated to be corrected in the next version of POSIX. GNU ‘m4’
+     follows traditional behavior in ‘syscmd’ where output is not
+     rescanned, and provides the extension ‘esyscmd’ that does scan the
+     output.
+
+   • At one point, POSIX required ‘changequote(ARG)’ (*note
+     Changequote::) to use newline as the close quote, but this was a
+     bug, and the next version of POSIX is anticipated to state that
+     using empty strings or just one argument is unspecified.
+     Meanwhile, the GNU ‘m4’ behavior of treating an empty end-quote
+     delimiter as ‘'’ is not portable, as Solaris treats it as repeating
+     the start-quote delimiter, and BSD treats it as leaving the
+     previous end-quote delimiter unchanged.  For predictable results,
+     never call changequote with just one argument, or with empty
+     strings for arguments.
+
+   • At one point, POSIX required ‘changecom(ARG,)’ (*note Changecom::)
+     to make it impossible to end a comment, but this is a bug, and the
+     next version of POSIX is anticipated to state that using empty
+     strings is unspecified.  Meanwhile, the GNU ‘m4’ behavior of
+     treating an empty end-comment delimiter as newline is not portable,
+     as BSD treats it as leaving the previous end-comment delimiter
+     unchanged.  It is also impossible in BSD implementations to disable
+     comments, even though that is required by POSIX. For predictable
+     results, never call changecom with empty strings for arguments.
+
+   • Most implementations of ‘m4’ give macros a higher precedence than
+     comments when parsing, meaning that if the start delimiter given to
+     ‘changecom’ (*note Changecom::) starts with a macro name, comments
+     are effectively disabled.  POSIX does not specify what the
+     precedence is, so this version of GNU ‘m4’ parser recognizes
+     comments, then macros, then quoted strings.
+
+   • Traditional implementations allow argument collection, but not
+     string and comment processing, to span file boundaries.  Thus, if
+     ‘a.m4’ contains ‘len(’, and ‘b.m4’ contains ‘abc)’, ‘m4 a.m4 b.m4’
+     outputs ‘3’ with traditional ‘m4’, but gives an error message that
+     the end of file was encountered inside a macro with GNU ‘m4’.  On
+     the other hand, traditional implementations do end of file
+     processing for files included with ‘include’ or ‘sinclude’ (*note
+     Include::), while GNU ‘m4’ seamlessly integrates the content of
+     those files.  Thus ‘include(`a.m4')include(`b.m4')’ will output ‘3’
+     instead of giving an error.
+
+   • Traditional ‘m4’ treats ‘traceon’ (*note Trace::) without arguments
+     as a global variable, independent of named macro tracing.  Also,
+     once a macro is undefined, named tracing of that macro is lost.  On
+     the other hand, when GNU ‘m4’ encounters ‘traceon’ without
+     arguments, it turns tracing on for all existing definitions at the
+     time, but does not trace future definitions; ‘traceoff’ without
+     arguments turns tracing off for all definitions regardless of
+     whether they were also traced by name; and tracing by name, such as
+     with ‘-tfoo’ at the command line or ‘traceon(`foo')’ in the input,
+     is an attribute that is preserved even if the macro is currently
+     undefined.
+
+     Additionally, while POSIX requires trace output, it makes no
+     demands on the formatting of that output.  Parsing trace output is
+     not guaranteed to be reliable, even between different releases of
+     GNU M4; however, the intent is that any future changes in trace
+     output will only occur under the direction of additional
+     ‘debugmode’ flags (*note Debug Levels::).
+
+   • POSIX requires ‘eval’ (*note Eval::) to treat all operators with
+     the same precedence as C.  However, earlier versions of GNU ‘m4’
+     followed the traditional behavior of other ‘m4’ implementations,
+     where bitwise and logical negation (‘~’ and ‘!’) have lower
+     precedence than equality operators; and where equality operators
+     (‘==’ and ‘!=’) had the same precedence as relational operators
+     (such as ‘<’).  Use explicit parentheses to ensure proper
+     precedence.  As extensions to POSIX, GNU ‘m4’ gives well-defined
+     semantics to operations that C leaves undefined, such as when
+     overflow occurs, when shifting negative numbers, or when performing
+     division by zero.  POSIX also requires ‘=’ to cause an error, but
+     many traditional implementations allowed it as an alias for ‘==’.
+
+   • POSIX 2001 requires ‘translit’ (*note Translit::) to treat each
+     character of the second and third arguments literally.  However, it
+     is anticipated that the next version of POSIX will allow the GNU
+     ‘m4’ behavior of treating ‘-’ as a range operator.
+
+   • POSIX requires ‘m4’ to honor the locale environment variables of
+     ‘LANG’, ‘LC_ALL’, ‘LC_CTYPE’, ‘LC_MESSAGES’, and ‘NLSPATH’, but
+     this has not yet been implemented in GNU ‘m4’.
+
+   • POSIX states that only unquoted leading newlines and blanks (that
+     is, space and tab) are ignored when collecting macro arguments.
+     However, this appears to be a bug in POSIX, since most traditional
+     implementations also ignore all whitespace (formfeed, carriage
+     return, and vertical tab).  GNU ‘m4’ follows tradition and ignores
+     all leading unquoted whitespace.
+
+   • A strictly-compliant POSIX client is not allowed to use
+     command-line arguments not specified by POSIX. However, since this
+     version of M4 ignores ‘POSIXLY_CORRECT’ and enables the option
+     ‘--gnu’ by default (*note Invoking m4: Limits control.), a client
+     desiring to be strictly compliant has no way to disable GNU
+     extensions that conflict with POSIX when directly invoking the
+     compiled ‘m4’.  A future version of ‘GNU’ M4 will honor the
+     environment variable ‘POSIXLY_CORRECT’, implicitly enabling
+     ‘--traditional’ if it is set, in order to allow a
+     strictly-compliant client.  In the meantime, a client needing
+     strict POSIX compliance can use the workaround of invoking a shell
+     script wrapper, where the wrapper then adds ‘--traditional’ to the
+     arguments passed to the compiled ‘m4’.

+
+16.3 Other incompatibilities
+============================
+
+There are a few other incompatibilities between this implementation of
+‘m4’, and the System V version.
+
+   • GNU ‘m4’ implements sync lines differently from System V ‘m4’, when
+     text is being diverted.  GNU ‘m4’ outputs the sync lines when the
+     text is being diverted, and System V ‘m4’ when the diverted text is
+     being brought back.
+
+     The problem is which lines and file names should be attached to
+     text that is being, or has been, diverted.  System V ‘m4’ regards
+     all the diverted text as being generated by the source line
+     containing the ‘undivert’ call, whereas GNU ‘m4’ regards the
+     diverted text as being generated at the time it is diverted.
+
+     The sync line option is used mostly when using ‘m4’ as a front end
+     to a compiler.  If a diverted line causes a compiler error, the
+     error messages should most probably refer to the place where the
+     diversion was made, and not where it was inserted again.
+
+          divert(2)2
+          divert(1)1
+          divert`'0
+          ⇒#line 3 "stdin"
+          ⇒0
+          ^D
+          ⇒#line 2 "stdin"
+          ⇒1
+          ⇒#line 1 "stdin"
+          ⇒2
+
+     The current ‘m4’ implementation has a limitation that the syncline
+     output at the start of each diversion occurs no matter what, even
+     if the previous diversion did not end with a newline.  This goes
+     contrary to the claim that synclines appear on a line by
+     themselves, so this limitation may be corrected in a future version
+     of ‘m4’.  In the meantime, when using ‘-s’, it is wisest to make
+     sure all diversions end with newline.
+
+   • GNU ‘m4’ makes no attempt at prohibiting self-referential
+     definitions like:
+
+          define(`x', `x')
+          ⇒
+          define(`x', `x ')
+          ⇒
+
+     There is nothing inherently wrong with defining ‘x’ to return ‘x’.
+     The wrong thing is to expand ‘x’ unquoted, because that would cause
+     an infinite rescan loop.  In ‘m4’, one might use macros to hold
+     strings, as we do for variables in other programming languages,
+     further checking them with:
+
+          ifelse(defn(`HOLDER'), `VALUE', ...)
+
+     In cases like this one, an interdiction for a macro to hold its own
+     name would be a useless limitation.  Of course, this leaves more
+     rope for the GNU ‘m4’ user to hang himself!  Rescanning hangs may
+     be avoided through careful programming, a little like for endless
+     loops in traditional programming languages.

+17.1 Solution for ‘exch’
+========================
+
+The ‘exch’ macro (*note Arguments::) as presented requires clients to
+double quote their arguments.  A nicer definition, which lets clients
+follow the rule of thumb of one level of quoting per level of
+parentheses, involves adding quotes in the definition of ‘exch’, as
+follows:
+
+     define(`exch', ``$2', `$1'')
+     ⇒
+     define(exch(`expansion text', `macro'))
+     ⇒
+     macro
+     ⇒expansion text

+
+17.2 Solution for ‘forloop’
+===========================
+
+The ‘forloop’ macro (*note Forloop::) as presented earlier can go into
+an infinite loop if given an iterator that is not parsed as a macro
+name.  It does not do any sanity checking on its numeric bounds, and
+only permits decimal numbers for bounds.  Here is an improved version,
+shipped as ‘m4-1.4.19/examples/forloop2.m4’; this version also optimizes
+overhead by calling four macros instead of six per iteration (excluding
+those in TEXT), by not dereferencing the ITERATOR in the helper
+‘_forloop’.
+
+     $ m4 -d -I examples
+     undivert(`forloop2.m4')dnl
+     ⇒divert(`-1')
+     ⇒# forloop(var, from, to, stmt) - improved version:
+     ⇒#   works even if VAR is not a strict macro name
+     ⇒#   performs sanity check that FROM is larger than TO
+     ⇒#   allows complex numerical expressions in TO and FROM
+     ⇒define(`forloop', `ifelse(eval(`($2) <= ($3)'), `1',
+     ⇒  `pushdef(`$1')_$0(`$1', eval(`$2'),
+     ⇒    eval(`$3'), `$4')popdef(`$1')')')
+     ⇒define(`_forloop',
+     ⇒  `define(`$1', `$2')$4`'ifelse(`$2', `$3', `',
+     ⇒    `$0(`$1', incr(`$2'), `$3', `$4')')')
+     ⇒divert`'dnl
+     include(`forloop2.m4')
+     ⇒
+     forloop(`i', `2', `1', `no iteration occurs')
+     ⇒
+     forloop(`', `1', `2', ` odd iterator name')
+     ⇒ odd iterator name odd iterator name
+     forloop(`i', `5 + 5', `0xc', ` 0x`'eval(i, `16')')
+     ⇒ 0xa 0xb 0xc
+     forloop(`i', `a', `b', `non-numeric bounds')
+     error→m4:stdin:6: bad expression in eval (bad input): (a) <= (b)
+     ⇒
+
+   One other change to notice is that the improved version used ‘_$0’
+rather than ‘_foreach’ to invoke the helper routine.  In general, this
+is a good practice to follow, because then the set of macros can be
+uniformly transformed.  The following example shows a transformation
+that doubles the current quoting and appends a suffix ‘2’ to each
+transformed macro.  If ‘foreach’ refers to the literal ‘_foreach’, then
+‘foreach2’ invokes ‘_foreach’ instead of the intended ‘_foreach2’, and
+the mixing of quoting paradigms leads to an infinite recursion loop in
+this example.

+     error→m4:stdin:12: recursion limit of 9 exceeded, use -L<N> to change it
+
+   One more optimization is still possible.  Instead of repeatedly
+assigning a variable then invoking or dereferencing it, it is possible
+to pass the current iterator value as a single argument.  Coupled with
+‘curry’ if other arguments are needed (*note Composition::), or with
+helper macros if the argument is needed in more than one place in the
+expansion, the output can be generated with three, rather than four,
+macros of overhead per iteration.  Notice how the file
+‘m4-1.4.19/examples/forloop3.m4’ rearranges the arguments of the helper
+‘_forloop’ to take two arguments that are placed around the current
+value.  By splitting a balanced set of parantheses across multiple
+arguments, the helper macro can now be shared by ‘forloop’ and the new
+‘forloop_arg’.
+
+     $ m4 -I examples
+     include(`forloop3.m4')
+     ⇒
+     undivert(`forloop3.m4')dnl
+     ⇒divert(`-1')

+     ⇒# forloop(var, from, to, stmt) - refactored to share code
+     ⇒define(`forloop', `ifelse(eval(`($2) <= ($3)'), `1',

+     ⇒divert`'dnl
+     forloop(`i', `1', `3', ` i')
+     ⇒ 1 2 3
+     define(`echo', `$@')
+     ⇒
+     forloop_arg(`1', `3', ` echo')
+     ⇒ 1 2 3
+     include(`curry.m4')
+     ⇒

+     ⇒2
+     popdef(`a')a
+     ⇒1
+     popdef(`a')a
+     ⇒a
+
+   Of course, it is possible to make even more improvements, such as
+adding an optional step argument, or allowing iteration through
+descending sequences.  GNU Autoconf provides some of these additional
+bells and whistles in its ‘m4_for’ macro.

+
+17.3 Solution for ‘foreach’
+===========================
+
+The ‘foreach’ and ‘foreachq’ macros (*note Foreach::) as presented
+earlier each have flaws.  First, we will examine and fix the quadratic
+behavior of ‘foreachq’:
+
+     $ m4 -I examples
+     include(`foreachq.m4')
+     ⇒
+     traceon(`shift')debugmode(`aq')
+     ⇒
+     foreachq(`x', ``1', `2', `3', `4'', `x
+     ')dnl
+     ⇒1
+     error→m4trace: -3- shift(`1', `2', `3', `4')
+     error→m4trace: -2- shift(`1', `2', `3', `4')
+     ⇒2
+     error→m4trace: -4- shift(`1', `2', `3', `4')
+     error→m4trace: -3- shift(`2', `3', `4')
+     error→m4trace: -3- shift(`1', `2', `3', `4')
+     error→m4trace: -2- shift(`2', `3', `4')
+     ⇒3
+     error→m4trace: -5- shift(`1', `2', `3', `4')
+     error→m4trace: -4- shift(`2', `3', `4')
+     error→m4trace: -3- shift(`3', `4')
+     error→m4trace: -4- shift(`1', `2', `3', `4')
+     error→m4trace: -3- shift(`2', `3', `4')
+     error→m4trace: -2- shift(`3', `4')
+     ⇒4
+     error→m4trace: -6- shift(`1', `2', `3', `4')
+     error→m4trace: -5- shift(`2', `3', `4')
+     error→m4trace: -4- shift(`3', `4')
+     error→m4trace: -3- shift(`4')
+
+   Each successive iteration was adding more quoted ‘shift’ invocations,
+and the entire list contents were passing through every iteration.  In
+general, when recursing, it is a good idea to make the recursion use
+fewer arguments, rather than adding additional quoted uses of ‘shift’.
+By doing so, ‘m4’ uses less memory, invokes fewer macros, is less likely
+to run into machine limits, and most importantly, performs faster.  The
+fixed version of ‘foreachq’ can be found in
+‘m4-1.4.19/examples/foreachq2.m4’:
+
+     $ m4 -I examples
+     include(`foreachq2.m4')
+     ⇒
+     undivert(`foreachq2.m4')dnl
+     ⇒include(`quote.m4')dnl
+     ⇒divert(`-1')
+     ⇒# foreachq(x, `item_1, item_2, ..., item_n', stmt)
+     ⇒#   quoted list, improved version
+     ⇒define(`foreachq', `pushdef(`$1')_$0($@)popdef(`$1')')
+     ⇒define(`_arg1q', ``$1'')
+     ⇒define(`_rest', `ifelse(`$#', `1', `', `dquote(shift($@))')')
+     ⇒define(`_foreachq', `ifelse(`$2', `', `',
+     ⇒  `define(`$1', _arg1q($2))$3`'$0(`$1', _rest($2), `$3')')')
+     ⇒divert`'dnl
+     traceon(`shift')debugmode(`aq')
+     ⇒
+     foreachq(`x', ``1', `2', `3', `4'', `x
+     ')dnl
+     ⇒1
+     error→m4trace: -3- shift(`1', `2', `3', `4')
+     ⇒2
+     error→m4trace: -3- shift(`2', `3', `4')
+     ⇒3
+     error→m4trace: -3- shift(`3', `4')
+     ⇒4
+
+   Note that the fixed version calls unquoted helper macros in
+‘_foreachq’ to trim elements immediately; those helper macros in turn
+must re-supply the layer of quotes lost in the macro invocation.
+Contrast the use of ‘_arg1q’, which quotes the first list element, with
+‘_arg1’ of the earlier implementation that returned the first list
+element directly.  Additionally, by calling the helper method
+immediately, the ‘defn(`ITERATOR')’ no longer contains unexpanded
+macros.
+
+   The astute m4 programmer might notice that the solution above still
+uses more memory and macro invocations, and thus more time, than
+strictly necessary.  Note that ‘$2’, which contains an arbitrarily long
+quoted list, is expanded and rescanned three times per iteration of
+‘_foreachq’.  Furthermore, every iteration of the algorithm effectively
+unboxes then reboxes the list, which costs a couple of macro
+invocations.  It is possible to rewrite the algorithm for a bit more
+speed by swapping the order of the arguments to ‘_foreachq’ in order to
+operate on an unboxed list in the first place, and by using the
+fixed-length ‘$#’ instead of an arbitrary length list as the key to end
+recursion.  The result is an overhead of six macro invocations per loop
+(excluding any macros in TEXT), instead of eight.  This alternative
+approach is available as ‘m4-1.4.19/examples/foreach3.m4’:
+
+     $ m4 -I examples
+     include(`foreachq3.m4')
+     ⇒

+     error→m4trace: -2- shift(`3', `4')
+
+   In the current version of M4, every instance of ‘$@’ is rescanned as
+it is encountered.  Thus, the ‘foreachq3.m4’ alternative uses much less
+memory than ‘foreachq2.m4’, and executes as much as 10% faster, since
+each iteration encounters fewer ‘$@’.  However, the implementation of
+rescanning every byte in ‘$@’ is quadratic in the number of bytes
+scanned (for example, making the broken version in ‘foreachq.m4’ cubic,
+rather than quadratic, in behavior).  A future release of M4 will
+improve the underlying implementation by reusing results of previous
+scans, so that both styles of ‘foreachq’ can become linear in the number
+of bytes scanned.  Notice how the implementation injects an empty
+argument prior to expanding ‘$2’ within ‘foreachq’; the helper macro
+‘_foreachq’ then ignores the third argument altogether, and ends
+recursion when there are three arguments left because there was nothing
+left to pass through ‘shift’.  Thus, each iteration only needs one
+‘ifelse’, rather than the two conditionals used in the version from
+‘foreachq2.m4’.
+
+   So far, all of the implementations of ‘foreachq’ presented have been
+quadratic with M4 1.4.x.  But ‘forloop’ is linear, because each
+iteration parses a constant amount of arguments.  So, it is possible to
+design a variant that uses ‘forloop’ to do the iteration, then uses ‘$@’
+only once at the end, giving a linear result even with older M4
+implementations.  This implementation relies on the GNU extension that
+‘$10’ expands to the tenth argument rather than the first argument
+concatenated with ‘0’.  The trick is to define an intermediate macro
+that repeats the text ‘m4_define(`$1', `$N')$2`'’, with ‘n’ set to
+successive integers corresponding to each argument.  The helper macro
+‘_foreachq_’ is needed in order to generate the literal sequences such
+as ‘$1’ into the intermediate macro, rather than expanding them as the
+arguments of ‘_foreachq’.  With this approach, no ‘shift’ calls are even
+needed!  Even though there are seven macros of overhead per iteration
+instead of six in ‘foreachq3.m4’, the linear scaling is apparent at
+relatively small list sizes.  However, this approach will need
+adjustment when a future version of M4 follows POSIX by no longer
+treating ‘$10’ as the tenth argument; the anticipation is that ‘${10}’
+can be used instead, although that alternative syntax is not yet
+supported.

+
+   For yet another approach, the improved version of ‘foreach’,
+available in ‘m4-1.4.19/examples/foreach2.m4’, simply overquotes the
+arguments to ‘_foreach’ to begin with, using ‘dquote_elt’.  Then
+‘_foreach’ can just use ‘_arg1’ to remove the extra layer of quoting
+that was added up front:

+     ⇒3
+     error→m4trace: -3- shift(``3'', ``4'')
+     ⇒4
+     error→m4trace: -3- shift(``4'')
+
+   It is likewise possible to write a variant of ‘foreach’ that performs
+in linear time on M4 1.4.x; the easiest method is probably writing a
+version of ‘foreach’ that unboxes its list, then invokes ‘_foreachq’ as
+previously defined in ‘foreachq4.m4’.
+
+   In summary, recursion over list elements is trickier than it appeared
+at first glance, but provides a powerful idiom within ‘m4’ processing.
+As a final demonstration, both list styles are now able to handle
+several scenarios that would wreak havoc on one or both of the original
+implementations.  This points out one other difference between the list
+styles.  ‘foreach’ evaluates unquoted list elements only once, in
+preparation for calling ‘_foreach’, similary for ‘foreachq’ as provided
+by ‘foreachq3.m4’ or ‘foreachq4.m4’.  But ‘foreachq’, as provided by
+‘foreachq2.m4’, evaluates unquoted list elements twice while visiting
+the first list element, once in ‘_arg1q’ and once in ‘_rest’.  When
+deciding which list style to use, one must take into account whether
+repeating the side effects of unquoted list elements will have any
+detrimental effects.

+17.4 Solution for ‘copy’
+========================
+
+The macro ‘copy’ presented above is unable to handle builtin tokens with
+M4 1.4.x, because it tries to pass the builtin token through the macro
+‘curry’, where it is silently flattened to an empty string (*note
+Composition::).  Rather than using the problematic ‘curry’ to work
+around the limitation that ‘stack_foreach’ expects to invoke a macro
+that takes exactly one argument, we can write a new macro that lets us
+form the exact two-argument ‘pushdef’ call sequence needed, so that we
+are no longer passing a builtin token through a text macro.
+
+ -- Composite: stack_foreach_sep (MACRO, PRE, POST, SEP)
+ -- Composite: stack_foreach_sep_lifo (MACRO, PRE, POST, SEP)
+     For each of the ‘pushdef’ definitions associated with MACRO, expand
+     the sequence ‘PRE`'definition`'POST’.  Additionally, expand SEP
+     between definitions.  ‘stack_foreach_sep’ visits the oldest
+     definition first, while ‘stack_foreach_sep_lifo’ visits the current
+     definition first.  The expansion may dereference MACRO, but should
+     not modify it.  There are a few special macros, such as ‘defn’,
+     which cannot be used as the MACRO parameter.
+
+   Note that ‘stack_foreach(`MACRO', `ACTION')’ is equivalent to
+‘stack_foreach_sep(`MACRO', `ACTION(', `)')’.  By supplying explicit
+parentheses, split among the PRE and POST arguments to
+‘stack_foreach_sep’, it is now possible to construct macro calls with
+more than one argument, without passing builtin tokens through a macro
+call.  It is likewise possible to directly reference the stack
+definitions without a macro call, by leaving PRE and POST empty.  Thus,
+in addition to fixing ‘copy’ on builtin tokens, it also executes with
+fewer macro invocations.
+
+   The new macro also adds a separator that is only output after the
+first iteration of the helper ‘_stack_reverse_sep’, implemented by
+prepending the original SEP to PRE and omitting a SEP argument in
+subsequent iterations.  Note that the empty string that separates SEP
+from PRE is provided as part of the fourth argument when originally
+calling ‘_stack_reverse_sep’, and not by writing ‘$4`'$3’ as the third
+argument in the recursive call; while the other approach would give the
+same output, it does so at the expense of increasing the argument size
+on each iteration of ‘_stack_reverse_sep’, which results in quadratic
+instead of linear execution time.  The improved stack walking macros are
+available in ‘m4-1.4.19/examples/stack_sep.m4’:
+
+     $ m4 -I examples
+     include(`stack_sep.m4')

+
+17.5 Solution for ‘m4wrap’
+==========================
+
+The replacement ‘m4wrap’ versions presented above, designed to guarantee
+FIFO or LIFO order regardless of the underlying M4 implementation, share
+a bug when dealing with wrapped text that looks like parameter
+expansion.  Note how the invocation of ‘m4wrapN’ interprets these
+parameters, while using the builtin preserves them for their intended
+use.
+
+     $ m4 -I examples
+     include(`wraplifo.m4')
+     ⇒
+     m4wrap(`define(`foo', ``$0:'-$1-$*-$#-')foo(`a', `b')
+     ')
+     ⇒
+     builtin(`m4wrap', ``'define(`bar', ``$0:'-$1-$*-$#-')bar(`a', `b')
+     ')
+     ⇒
+     ^D
+     ⇒bar:-a-a,b-2-
+     ⇒m4wrap0:---0-
+
+   Additionally, the computation of ‘_m4wrap_level’ and creation of
+multiple ‘m4wrapN’ placeholders in the original examples is more
+expensive in time and memory than strictly necessary.  Notice how the
+improved version grabs the wrapped text via ‘defn’ to avoid parameter
+expansion, then undefines ‘_m4wrap_text’, before stripping a level of
+quotes with ‘_arg1’ to expand the text.  That way, each level of
+wrapping reuses the single placeholder, which starts each nesting level
+in an undefined state.
+
+   Finally, it is worth emulating the GNU M4 extension of saving all
+arguments to ‘m4wrap’, separated by a space, rather than saving just the
+first argument.  This is done with the ‘join’ macro documented
+previously (*note Shift::).  The improved LIFO example is shipped as
+‘m4-1.4.19/examples/wraplifo2.m4’, and can easily be converted to a FIFO
+solution by swapping the adjacent invocations of ‘joinall’ and ‘defn’.
+
+     $ m4 -I examples
+     include(`wraplifo2.m4')
+     ⇒

+
+The ‘cleardivert’ macro (*note Cleardivert::) cannot, as it stands, be

+
+17.7 Solution for ‘capitalize’
+==============================
+
+The ‘capitalize’ macro (*note Patsubst::) as presented earlier does not
+allow clients to follow the quoting rule of thumb.  Consider the three
+macros ‘active’, ‘Active’, and ‘ACTIVE’, and the difference between
+calling ‘capitalize’ with the expansion of a macro, expanding the result
+of a case change, and changing the case of a double-quoted string:
+
+     $ m4 -I examples
+     include(`capitalize.m4')dnl
+     define(`active', `act1, ive')dnl
+     define(`Active', `Act2, Ive')dnl
+     define(`ACTIVE', `ACT3, IVE')dnl
+     upcase(active)
+     ⇒ACT1,IVE
+     upcase(`active')
+     ⇒ACT3, IVE
+     upcase(``active'')
+     ⇒ACTIVE
+     downcase(ACTIVE)
+     ⇒act3,ive
+     downcase(`ACTIVE')
+     ⇒act1, ive
+     downcase(``ACTIVE'')
+     ⇒active
+     capitalize(active)
+     ⇒Act1
+     capitalize(`active')
+     ⇒Active
+     capitalize(``active'')
+     ⇒_capitalize(`active')
+     define(`A', `OOPS')
+     ⇒
+     capitalize(active)
+     ⇒OOPSct1
+     capitalize(`active')
+     ⇒OOPSctive
+
+   First, when ‘capitalize’ is called with more than one argument, it
+was throwing away later arguments, whereas ‘upcase’ and ‘downcase’ used
+‘$*’ to collect them all.  The fix is simple: use ‘$*’ consistently.
+
+   Next, with single-quoting, ‘capitalize’ outputs a single character, a
+set of quotes, then the rest of the characters, making it impossible to
+invoke ‘Active’ after the fact, and allowing the alternate macro ‘A’ to
+interfere.  Here, the solution is to use additional quoting in the
+helper macros, then pass the final over-quoted output string through
+‘_arg1’ to remove the extra quoting and finally invoke the concatenated
+portions as a single string.
+
+   Finally, when passed a double-quoted string, the nested macro
+‘_capitalize’ is never invoked because it ended up nested inside quotes.
+This one is the toughest to fix.  In short, we have no idea how many
+levels of quotes are in effect on the substring being altered by
+‘patsubst’.  If the replacement string cannot be expressed entirely in
+terms of literal text and backslash substitutions, then we need a
+mechanism to guarantee that the helper macros are invoked outside of
+quotes.  In other words, this sounds like a job for ‘changequote’ (*note
+Changequote::).  By changing the active quoting characters, we can
+guarantee that replacement text injected by ‘patsubst’ always occurs in
+the middle of a string that has exactly one level of over-quoting using
+alternate quotes; so the replacement text closes the quoted string,
+invokes the helper macros, then reopens the quoted string.  In turn,
+that means the replacement text has unbalanced quotes, necessitating
+another round of ‘changequote’.
+
+   In the fixed version below, (also shipped as
+‘m4-1.4.19/examples/capitalize2.m4’), ‘capitalize’ uses the alternate
+quotes of ‘<<’ and ‘>>’ (the longer strings are chosen so as to be
+less likely to appear in the text being converted).  The helpers
+‘_to_alt’ and ‘_from_alt’ merely reduce the number of characters
+required to perform a ‘changequote’, since the definition changes twice.
+The outermost pair means that ‘patsubst’ and ‘_capitalize_alt’ are
+invoked with alternate quoting; the innermost pair is used so that the
+third argument to ‘patsubst’ can contain an unbalanced ‘>>’/‘<<’ pair.
+Note that ‘upcase’ and ‘downcase’ must be redefined as ‘_upcase_alt’ and
+‘_downcase_alt’, since they contain nested quotes but are invoked with
+the alternate quoting scheme in effect.

+17.8 Solution for ‘fatal_error’
+===============================
+
+The ‘fatal_error’ macro (*note M4exit::) is not robust to versions of
+GNU M4 earlier than 1.4.8, where invoking ‘__file__’ (*note Location::)
+inside ‘m4wrap’ would result in an empty string, and ‘__line__’ resulted
+in ‘0’ even though all files start at line 1.  Furthermore, versions
+earlier than 1.4.6 did not support the ‘__program__’ macro.  If you want
+‘fatal_error’ to work across the entire 1.4.x release series, a better
+implementation would be:
+
+     define(`fatal_error',
+       `errprint(ifdef(`__program__', `__program__', ``m4'')'dnl
+     `:ifelse(__line__, `0', `',

+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+   Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+   For the developers’ and authors’ protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users’ and
+authors’ sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+   Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users’ freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+   Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+   The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS
+====================
+
+  0. Definitions.
+
+     “This License” refers to version 3 of the GNU General Public
+     License.
+
+     “Copyright” also means copyright-like laws that apply to other
+     kinds of works, such as semiconductor masks.
+
+     “The Program” refers to any copyrightable work licensed under this
+     License.  Each licensee is addressed as “you”.  “Licensees” and
+     “recipients” may be individuals or organizations.
+
+     To “modify” a work means to copy from or adapt all or part of the
+     work in a fashion requiring copyright permission, other than the
+     making of an exact copy.  The resulting work is called a “modified
+     version” of the earlier work or a work “based on” the earlier work.
+
+     A “covered work” means either the unmodified Program or a work
+     based on the Program.
+
+     To “propagate” a work means to do anything with it that, without
+     permission, would make you directly or secondarily liable for
+     infringement under applicable copyright law, except executing it on
+     a computer or modifying a private copy.  Propagation includes
+     copying, distribution (with or without modification), making
+     available to the public, and in some countries other activities as
+     well.
+
+     To “convey” a work means any kind of propagation that enables other
+     parties to make or receive copies.  Mere interaction with a user
+     through a computer network, with no transfer of a copy, is not
+     conveying.
+
+     An interactive user interface displays “Appropriate Legal Notices”
+     to the extent that it includes a convenient and prominently visible
+     feature that (1) displays an appropriate copyright notice, and (2)
+     tells the user that there is no warranty for the work (except to
+     the extent that warranties are provided), that licensees may convey
+     the work under this License, and how to view a copy of this
+     License.  If the interface presents a list of user commands or
+     options, such as a menu, a prominent item in the list meets this
+     criterion.
+
+  1. Source Code.
+
+     The “source code” for a work means the preferred form of the work
+     for making modifications to it.  “Object code” means any non-source
+     form of a work.
+
+     A “Standard Interface” means an interface that either is an
+     official standard defined by a recognized standards body, or, in
+     the case of interfaces specified for a particular programming
+     language, one that is widely used among developers working in that
+     language.
+
+     The “System Libraries” of an executable work include anything,
+     other than the work as a whole, that (a) is included in the normal
+     form of packaging a Major Component, but which is not part of that
+     Major Component, and (b) serves only to enable use of the work with
+     that Major Component, or to implement a Standard Interface for
+     which an implementation is available to the public in source code
+     form.  A “Major Component”, in this context, means a major
+     essential component (kernel, window system, and so on) of the
+     specific operating system (if any) on which the executable work
+     runs, or a compiler used to produce the work, or an object code
+     interpreter used to run it.
+
+     The “Corresponding Source” for a work in object code form means all
+     the source code needed to generate, install, and (for an executable
+     work) run the object code and to modify the work, including scripts
+     to control those activities.  However, it does not include the
+     work’s System Libraries, or general-purpose tools or generally
+     available free programs which are used unmodified in performing
+     those activities but which are not part of the work.  For example,
+     Corresponding Source includes interface definition files associated
+     with source files for the work, and the source code for shared
+     libraries and dynamically linked subprograms that the work is
+     specifically designed to require, such as by intimate data
+     communication or control flow between those subprograms and other
+     parts of the work.
+
+     The Corresponding Source need not include anything that users can
+     regenerate automatically from other parts of the Corresponding
+     Source.
+
+     The Corresponding Source for a work in source code form is that
+     same work.
+
+  2. Basic Permissions.
+
+     All rights granted under this License are granted for the term of
+     copyright on the Program, and are irrevocable provided the stated
+     conditions are met.  This License explicitly affirms your unlimited
+     permission to run the unmodified Program.  The output from running
+     a covered work is covered by this License only if the output, given
+     its content, constitutes a covered work.  This License acknowledges
+     your rights of fair use or other equivalent, as provided by
+     copyright law.
+
+     You may make, run and propagate covered works that you do not
+     convey, without conditions so long as your license otherwise
+     remains in force.  You may convey covered works to others for the
+     sole purpose of having them make modifications exclusively for you,
+     or provide you with facilities for running those works, provided
+     that you comply with the terms of this License in conveying all
+     material for which you do not control copyright.  Those thus making
+     or running the covered works for you must do so exclusively on your
+     behalf, under your direction and control, on terms that prohibit
+     them from making any copies of your copyrighted material outside
+     their relationship with you.
+
+     Conveying under any other circumstances is permitted solely under
+     the conditions stated below.  Sublicensing is not allowed; section
+     10 makes it unnecessary.
+
+  3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
+
+     No covered work shall be deemed part of an effective technological
+     measure under any applicable law fulfilling obligations under
+     article 11 of the WIPO copyright treaty adopted on 20 December
+     1996, or similar laws prohibiting or restricting circumvention of
+     such measures.
+
+     When you convey a covered work, you waive any legal power to forbid
+     circumvention of technological measures to the extent such
+     circumvention is effected by exercising rights under this License
+     with respect to the covered work, and you disclaim any intention to
+     limit operation or modification of the work as a means of
+     enforcing, against the work’s users, your or third parties’ legal
+     rights to forbid circumvention of technological measures.
+
+  4. Conveying Verbatim Copies.
+
+     You may convey verbatim copies of the Program’s source code as you
+     receive it, in any medium, provided that you conspicuously and
+     appropriately publish on each copy an appropriate copyright notice;
+     keep intact all notices stating that this License and any
+     non-permissive terms added in accord with section 7 apply to the
+     code; keep intact all notices of the absence of any warranty; and
+     give all recipients a copy of this License along with the Program.
+
+     You may charge any price or no price for each copy that you convey,
+     and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+     You may convey a work based on the Program, or the modifications to
+     produce it from the Program, in the form of source code under the
+     terms of section 4, provided that you also meet all of these
+     conditions:
+
+       a. The work must carry prominent notices stating that you
+          modified it, and giving a relevant date.
+
+       b. The work must carry prominent notices stating that it is
+          released under this License and any conditions added under
+          section 7.  This requirement modifies the requirement in
+          section 4 to “keep intact all notices”.
+
+       c. You must license the entire work, as a whole, under this
+          License to anyone who comes into possession of a copy.  This
+          License will therefore apply, along with any applicable
+          section 7 additional terms, to the whole of the work, and all
+          its parts, regardless of how they are packaged.  This License
+          gives no permission to license the work in any other way, but
+          it does not invalidate such permission if you have separately
+          received it.
+
+       d. If the work has interactive user interfaces, each must display
+          Appropriate Legal Notices; however, if the Program has
+          interactive interfaces that do not display Appropriate Legal
+          Notices, your work need not make them do so.
+
+     A compilation of a covered work with other separate and independent
+     works, which are not by their nature extensions of the covered
+     work, and which are not combined with it such as to form a larger
+     program, in or on a volume of a storage or distribution medium, is
+     called an “aggregate” if the compilation and its resulting
+     copyright are not used to limit the access or legal rights of the
+     compilation’s users beyond what the individual works permit.
+     Inclusion of a covered work in an aggregate does not cause this
+     License to apply to the other parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+     You may convey a covered work in object code form under the terms
+     of sections 4 and 5, provided that you also convey the
+     machine-readable Corresponding Source under the terms of this
+     License, in one of these ways:
+
+       a. Convey the object code in, or embodied in, a physical product
+          (including a physical distribution medium), accompanied by the
+          Corresponding Source fixed on a durable physical medium
+          customarily used for software interchange.
+
+       b. Convey the object code in, or embodied in, a physical product
+          (including a physical distribution medium), accompanied by a
+          written offer, valid for at least three years and valid for as
+          long as you offer spare parts or customer support for that
+          product model, to give anyone who possesses the object code
+          either (1) a copy of the Corresponding Source for all the
+          software in the product that is covered by this License, on a
+          durable physical medium customarily used for software
+          interchange, for a price no more than your reasonable cost of
+          physically performing this conveying of source, or (2) access
+          to copy the Corresponding Source from a network server at no
+          charge.
+
+       c. Convey individual copies of the object code with a copy of the
+          written offer to provide the Corresponding Source.  This
+          alternative is allowed only occasionally and noncommercially,
+          and only if you received the object code with such an offer,
+          in accord with subsection 6b.
+
+       d. Convey the object code by offering access from a designated
+          place (gratis or for a charge), and offer equivalent access to
+          the Corresponding Source in the same way through the same
+          place at no further charge.  You need not require recipients
+          to copy the Corresponding Source along with the object code.
+          If the place to copy the object code is a network server, the
+          Corresponding Source may be on a different server (operated by
+          you or a third party) that supports equivalent copying
+          facilities, provided you maintain clear directions next to the
+          object code saying where to find the Corresponding Source.
+          Regardless of what server hosts the Corresponding Source, you
+          remain obligated to ensure that it is available for as long as
+          needed to satisfy these requirements.
+
+       e. Convey the object code using peer-to-peer transmission,
+          provided you inform other peers where the object code and
+          Corresponding Source of the work are being offered to the
+          general public at no charge under subsection 6d.
+
+     A separable portion of the object code, whose source code is
+     excluded from the Corresponding Source as a System Library, need
+     not be included in conveying the object code work.
+
+     A “User Product” is either (1) a “consumer product”, which means
+     any tangible personal property which is normally used for personal,
+     family, or household purposes, or (2) anything designed or sold for
+     incorporation into a dwelling.  In determining whether a product is
+     a consumer product, doubtful cases shall be resolved in favor of
+     coverage.  For a particular product received by a particular user,
+     “normally used” refers to a typical or common use of that class of
+     product, regardless of the status of the particular user or of the
+     way in which the particular user actually uses, or expects or is
+     expected to use, the product.  A product is a consumer product
+     regardless of whether the product has substantial commercial,
+     industrial or non-consumer uses, unless such uses represent the
+     only significant mode of use of the product.
+
+     “Installation Information” for a User Product means any methods,
+     procedures, authorization keys, or other information required to
+     install and execute modified versions of a covered work in that
+     User Product from a modified version of its Corresponding Source.
+     The information must suffice to ensure that the continued
+     functioning of the modified object code is in no case prevented or
+     interfered with solely because modification has been made.
+
+     If you convey an object code work under this section in, or with,
+     or specifically for use in, a User Product, and the conveying
+     occurs as part of a transaction in which the right of possession
+     and use of the User Product is transferred to the recipient in
+     perpetuity or for a fixed term (regardless of how the transaction
+     is characterized), the Corresponding Source conveyed under this
+     section must be accompanied by the Installation Information.  But
+     this requirement does not apply if neither you nor any third party
+     retains the ability to install modified object code on the User
+     Product (for example, the work has been installed in ROM).
+
+     The requirement to provide Installation Information does not
+     include a requirement to continue to provide support service,
+     warranty, or updates for a work that has been modified or installed
+     by the recipient, or for the User Product in which it has been
+     modified or installed.  Access to a network may be denied when the
+     modification itself materially and adversely affects the operation
+     of the network or violates the rules and protocols for
+     communication across the network.
+
+     Corresponding Source conveyed, and Installation Information
+     provided, in accord with this section must be in a format that is
+     publicly documented (and with an implementation available to the
+     public in source code form), and must require no special password
+     or key for unpacking, reading or copying.
+
+  7. Additional Terms.
+
+     “Additional permissions” are terms that supplement the terms of
+     this License by making exceptions from one or more of its
+     conditions.  Additional permissions that are applicable to the
+     entire Program shall be treated as though they were included in
+     this License, to the extent that they are valid under applicable
+     law.  If additional permissions apply only to part of the Program,
+     that part may be used separately under those permissions, but the
+     entire Program remains governed by this License without regard to
+     the additional permissions.
+
+     When you convey a copy of a covered work, you may at your option
+     remove any additional permissions from that copy, or from any part
+     of it.  (Additional permissions may be written to require their own
+     removal in certain cases when you modify the work.)  You may place
+     additional permissions on material, added by you to a covered work,
+     for which you have or can give appropriate copyright permission.
+
+     Notwithstanding any other provision of this License, for material
+     you add to a covered work, you may (if authorized by the copyright
+     holders of that material) supplement the terms of this License with
+     terms:
+
+       a. Disclaiming warranty or limiting liability differently from
+          the terms of sections 15 and 16 of this License; or
+
+       b. Requiring preservation of specified reasonable legal notices
+          or author attributions in that material or in the Appropriate
+          Legal Notices displayed by works containing it; or
+
+       c. Prohibiting misrepresentation of the origin of that material,
+          or requiring that modified versions of such material be marked
+          in reasonable ways as different from the original version; or
+
+       d. Limiting the use for publicity purposes of names of licensors
+          or authors of the material; or
+
+       e. Declining to grant rights under trademark law for use of some
+          trade names, trademarks, or service marks; or
+
+       f. Requiring indemnification of licensors and authors of that
+          material by anyone who conveys the material (or modified
+          versions of it) with contractual assumptions of liability to
+          the recipient, for any liability that these contractual
+          assumptions directly impose on those licensors and authors.
+
+     All other non-permissive additional terms are considered “further
+     restrictions” within the meaning of section 10.  If the Program as
+     you received it, or any part of it, contains a notice stating that
+     it is governed by this License along with a term that is a further
+     restriction, you may remove that term.  If a license document
+     contains a further restriction but permits relicensing or conveying
+     under this License, you may add to a covered work material governed
+     by the terms of that license document, provided that the further
+     restriction does not survive such relicensing or conveying.
+
+     If you add terms to a covered work in accord with this section, you
+     must place, in the relevant source files, a statement of the
+     additional terms that apply to those files, or a notice indicating
+     where to find the applicable terms.
+
+     Additional terms, permissive or non-permissive, may be stated in
+     the form of a separately written license, or stated as exceptions;
+     the above requirements apply either way.
+
+  8. Termination.
+
+     You may not propagate or modify a covered work except as expressly
+     provided under this License.  Any attempt otherwise to propagate or
+     modify it is void, and will automatically terminate your rights
+     under this License (including any patent licenses granted under the
+     third paragraph of section 11).
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly and
+     finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from you
+     under this License.  If your rights have been terminated and not
+     permanently reinstated, you do not qualify to receive new licenses
+     for the same material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+     You are not required to accept this License in order to receive or
+     run a copy of the Program.  Ancillary propagation of a covered work
+     occurring solely as a consequence of using peer-to-peer
+     transmission to receive a copy likewise does not require
+     acceptance.  However, nothing other than this License grants you
+     permission to propagate or modify any covered work.  These actions
+     infringe copyright if you do not accept this License.  Therefore,
+     by modifying or propagating a covered work, you indicate your
+     acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+     Each time you convey a covered work, the recipient automatically
+     receives a license from the original licensors, to run, modify and
+     propagate that work, subject to this License.  You are not
+     responsible for enforcing compliance by third parties with this
+     License.
+
+     An “entity transaction” is a transaction transferring control of an
+     organization, or substantially all assets of one, or subdividing an
+     organization, or merging organizations.  If propagation of a
+     covered work results from an entity transaction, each party to that
+     transaction who receives a copy of the work also receives whatever
+     licenses to the work the party’s predecessor in interest had or
+     could give under the previous paragraph, plus a right to possession
+     of the Corresponding Source of the work from the predecessor in
+     interest, if the predecessor has it or can get it with reasonable
+     efforts.
+
+     You may not impose any further restrictions on the exercise of the
+     rights granted or affirmed under this License.  For example, you
+     may not impose a license fee, royalty, or other charge for exercise
+     of rights granted under this License, and you may not initiate
+     litigation (including a cross-claim or counterclaim in a lawsuit)
+     alleging that any patent claim is infringed by making, using,
+     selling, offering for sale, or importing the Program or any portion
+     of it.
+
+  11. Patents.
+
+     A “contributor” is a copyright holder who authorizes use under this
+     License of the Program or a work on which the Program is based.
+     The work thus licensed is called the contributor’s “contributor
+     version”.
+
+     A contributor’s “essential patent claims” are all patent claims
+     owned or controlled by the contributor, whether already acquired or
+     hereafter acquired, that would be infringed by some manner,
+     permitted by this License, of making, using, or selling its
+     contributor version, but do not include claims that would be
+     infringed only as a consequence of further modification of the
+     contributor version.  For purposes of this definition, “control”
+     includes the right to grant patent sublicenses in a manner
+     consistent with the requirements of this License.
+
+     Each contributor grants you a non-exclusive, worldwide,
+     royalty-free patent license under the contributor’s essential
+     patent claims, to make, use, sell, offer for sale, import and
+     otherwise run, modify and propagate the contents of its contributor
+     version.
+
+     In the following three paragraphs, a “patent license” is any
+     express agreement or commitment, however denominated, not to
+     enforce a patent (such as an express permission to practice a
+     patent or covenant not to sue for patent infringement).  To “grant”
+     such a patent license to a party means to make such an agreement or
+     commitment not to enforce a patent against the party.
+
+     If you convey a covered work, knowingly relying on a patent
+     license, and the Corresponding Source of the work is not available
+     for anyone to copy, free of charge and under the terms of this
+     License, through a publicly available network server or other
+     readily accessible means, then you must either (1) cause the
+     Corresponding Source to be so available, or (2) arrange to deprive
+     yourself of the benefit of the patent license for this particular
+     work, or (3) arrange, in a manner consistent with the requirements
+     of this License, to extend the patent license to downstream
+     recipients.  “Knowingly relying” means you have actual knowledge
+     that, but for the patent license, your conveying the covered work
+     in a country, or your recipient’s use of the covered work in a
+     country, would infringe one or more identifiable patents in that
+     country that you have reason to believe are valid.
+
+     If, pursuant to or in connection with a single transaction or
+     arrangement, you convey, or propagate by procuring conveyance of, a
+     covered work, and grant a patent license to some of the parties
+     receiving the covered work authorizing them to use, propagate,
+     modify or convey a specific copy of the covered work, then the
+     patent license you grant is automatically extended to all
+     recipients of the covered work and works based on it.
+
+     A patent license is “discriminatory” if it does not include within
+     the scope of its coverage, prohibits the exercise of, or is
+     conditioned on the non-exercise of one or more of the rights that
+     are specifically granted under this License.  You may not convey a
+     covered work if you are a party to an arrangement with a third
+     party that is in the business of distributing software, under which
+     you make payment to the third party based on the extent of your
+     activity of conveying the work, and under which the third party
+     grants, to any of the parties who would receive the covered work
+     from you, a discriminatory patent license (a) in connection with
+     copies of the covered work conveyed by you (or copies made from
+     those copies), or (b) primarily for and in connection with specific
+     products or compilations that contain the covered work, unless you
+     entered into that arrangement, or that patent license was granted,
+     prior to 28 March 2007.
+
+     Nothing in this License shall be construed as excluding or limiting
+     any implied license or other defenses to infringement that may
+     otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others’ Freedom.
+
+     If conditions are imposed on you (whether by court order, agreement
+     or otherwise) that contradict the conditions of this License, they
+     do not excuse you from the conditions of this License.  If you
+     cannot convey a covered work so as to satisfy simultaneously your
+     obligations under this License and any other pertinent obligations,
+     then as a consequence you may not convey it at all.  For example,
+     if you agree to terms that obligate you to collect a royalty for
+     further conveying from those to whom you convey the Program, the
+     only way you could satisfy both those terms and this License would
+     be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+     Notwithstanding any other provision of this License, you have
+     permission to link or combine any covered work with a work licensed
+     under version 3 of the GNU Affero General Public License into a
+     single combined work, and to convey the resulting work.  The terms
+     of this License will continue to apply to the part which is the
+     covered work, but the special requirements of the GNU Affero
+     General Public License, section 13, concerning interaction through
+     a network will apply to the combination as such.
+
+  14. Revised Versions of this License.
+
+     The Free Software Foundation may publish revised and/or new
+     versions of the GNU General Public License from time to time.  Such
+     new versions will be similar in spirit to the present version, but
+     may differ in detail to address new problems or concerns.
+
+     Each version is given a distinguishing version number.  If the
+     Program specifies that a certain numbered version of the GNU
+     General Public License “or any later version” applies to it, you
+     have the option of following the terms and conditions either of
+     that numbered version or of any later version published by the Free
+     Software Foundation.  If the Program does not specify a version
+     number of the GNU General Public License, you may choose any
+     version ever published by the Free Software Foundation.
+
+     If the Program specifies that a proxy can decide which future
+     versions of the GNU General Public License can be used, that
+     proxy’s public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Program.
+
+     Later license versions may give you additional or different
+     permissions.  However, no additional obligations are imposed on any
+     author or copyright holder as a result of your choosing to follow a
+     later version.
+
+  15. Disclaimer of Warranty.
+
+     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+     APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+     COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS”
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+     INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+     MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE
+     RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
+     SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+     NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+     WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
+     AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+     DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+     CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
+     THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
+     BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+     PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF
+     THE POSSIBILITY OF SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+     If the disclaimer of warranty and limitation of liability provided
+     above cannot be given local legal effect according to their terms,
+     reviewing courts shall apply local law that most closely
+     approximates an absolute waiver of all civil liability in
+     connection with the Program, unless a warranty or assumption of
+     liability accompanies a copy of the Program in return for a fee.

+END OF TERMS AND CONDITIONS
+===========================
+
+How to Apply These Terms to Your New Programs
+=============================================
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+   To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least the
+“copyright” line and a pointer to where the full notice is found.
+
+     ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.
+     Copyright (C) YEAR NAME OF AUTHOR
+
+     This program is free software: you can redistribute it and/or modify
+     it under the terms of the GNU General Public License as published by
+     the Free Software Foundation, either version 3 of the License, or (at
+     your option) any later version.
+
+     This program is distributed in the hope that it will be useful, but
+     WITHOUT ANY WARRANTY; without even the implied warranty of
+     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+     General Public License for more details.
+
+     You should have received a copy of the GNU General Public License
+     along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+   Also add information on how to contact you by electronic and paper
+mail.
+
+   If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+     PROGRAM Copyright (C) YEAR NAME OF AUTHOR
+     This program comes with ABSOLUTELY NO WARRANTY; for details type ‘show w’.
+     This is free software, and you are welcome to redistribute it
+     under certain conditions; type ‘show c’ for details.
+
+   The hypothetical commands ‘show w’ and ‘show c’ should show the
+appropriate parts of the General Public License.  Of course, your
+program’s commands might be different; for a GUI interface, you would
+use an “about box”.
+
+   You should also get your employer (if you work as a programmer) or
+school, if any, to sign a “copyright disclaimer” for the program, if
+necessary.  For more information on this, and how to apply and follow
+the GNU GPL, see <https://www.gnu.org/licenses/>.
+
+   The GNU General Public License does not permit incorporating your
+program into proprietary programs.  If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library.  If this is what you want to do, use the
+GNU Lesser General Public License instead of this License.  But first,
+please read <https://www.gnu.org/licenses/why-not-lgpl.html>.

+===================================
+
+                     Version 1.3, 3 November 2008
+
+     Copyright © 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+     <https://fsf.org/>
+
+     Everyone is permitted to copy and distribute verbatim copies
+     of this license document, but changing it is not allowed.
+
+  0. PREAMBLE
+
+     The purpose of this License is to make a manual, textbook, or other
+     functional and useful document “free” in the sense of freedom: to
+     assure everyone the effective freedom to copy and redistribute it,
+     with or without modifying it, either commercially or
+     noncommercially.  Secondarily, this License preserves for the
+     author and publisher a way to get credit for their work, while not
+     being considered responsible for modifications made by others.
+
+     This License is a kind of “copyleft”, which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.  We
+     recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it can
+     be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     “Document”, below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as “you”.  You accept
+     the license if you copy, modify or distribute the work in a way
+     requiring permission under copyright law.
+
+     A “Modified Version” of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A “Secondary Section” is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document’s overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The “Invariant Sections” are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in the
+     notice that says that the Document is released under this License.
+     If a section does not fit the above definition of Secondary then it
+     is not allowed to be designated as Invariant.  The Document may
+     contain zero Invariant Sections.  If the Document does not identify
+     any Invariant Sections then there are none.
+
+     The “Cover Texts” are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A “Transparent” copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images composed
+     of pixels) generic paint programs or (for drawings) some widely
+     available drawing editor, and that is suitable for input to text
+     formatters or for automatic translation to a variety of formats
+     suitable for input to text formatters.  A copy made in an otherwise
+     Transparent file format whose markup, or absence of markup, has
+     been arranged to thwart or discourage subsequent modification by
+     readers is not Transparent.  An image format is not Transparent if
+     used for any substantial amount of text.  A copy that is not
+     “Transparent” is called “Opaque”.
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and standard-conforming
+     simple HTML, PostScript or PDF designed for human modification.
+     Examples of transparent image formats include PNG, XCF and JPG.
+     Opaque formats include proprietary formats that can be read and
+     edited only by proprietary word processors, SGML or XML for which
+     the DTD and/or processing tools are not generally available, and
+     the machine-generated HTML, PostScript or PDF produced by some word
+     processors for output purposes only.
+
+     The “Title Page” means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, “Title
+     Page” means the text near the most prominent appearance of the
+     work’s title, preceding the beginning of the body of the text.
+
+     The “publisher” means any person or entity that distributes copies
+     of the Document to the public.
+
+     A section “Entitled XYZ” means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.)
+     To “Preserve the Title” of such a section when you modify the
+     Document means that it remains a section “Entitled XYZ” according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow the
+     conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document’s license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the title
+     equally prominent and visible.  You may add other material on the
+     covers in addition.  Copying with changes limited to the covers, as
+     long as they preserve the title of the Document and satisfy these
+     conditions, can be treated as verbatim copying in other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a machine-readable
+     Transparent copy along with each Opaque copy, or state in or with
+     each Opaque copy a computer-network location from which the general
+     network-using public has access to download using public-standard
+     network protocols a complete Transparent copy of the Document, free
+     of added material.  If you use the latter option, you must take
+     reasonably prudent steps, when you begin distribution of Opaque
+     copies in quantity, to ensure that this Transparent copy will
+     remain thus accessible at the stated location until at least one
+     year after the last time you distribute an Opaque copy (directly or
+     through your agents or retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of copies,
+     to give them a chance to provide you with an updated version of the
+     Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with the
+     Modified Version filling the role of the Document, thus licensing
+     distribution and modification of the Modified Version to whoever
+     possesses a copy of it.  In addition, you must do these things in
+     the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of previous
+          versions (which should, if there were any, be listed in the
+          History section of the Document).  You may use the same title
+          as a previous version if the original publisher of that
+          version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document’s
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled “History”, Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on the
+          Title Page.  If there is no section Entitled “History” in the
+          Document, create one stating the title, year, authors, and
+          publisher of the Document as given on its Title Page, then add
+          an item describing the Modified Version as stated in the
+          previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in the
+          “History” section.  You may omit a network location for a work
+          that was published at least four years before the Document
+          itself, or if the original publisher of the version it refers
+          to gives permission.
+
+       K. For any section Entitled “Acknowledgements” or “Dedications”,
+          Preserve the Title of the section, and preserve in the section
+          all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document, unaltered
+          in their text and in their titles.  Section numbers or the
+          equivalent are not considered part of the section titles.
+
+       M. Delete any section Entitled “Endorsements”.  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          “Endorsements” or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option designate
+     some or all of these sections as invariant.  To do this, add their
+     titles to the list of Invariant Sections in the Modified Version’s
+     license notice.  These titles must be distinct from any other
+     section titles.
+
+     You may add a section Entitled “Endorsements”, provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties—for example, statements of peer review or that the text has
+     been approved by an organization as the authoritative definition of
+     a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end of
+     the list of Cover Texts in the Modified Version.  Only one passage
+     of Front-Cover Text and one of Back-Cover Text may be added by (or
+     through arrangements made by) any one entity.  If the Document
+     already includes a cover text for the same cover, previously added
+     by you or by arrangement made by the same entity you are acting on
+     behalf of, you may not add another; but you may replace the old
+     one, on explicit permission from the previous publisher that added
+     the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination all
+     of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     “History” in the various original documents, forming one section
+     Entitled “History”; likewise combine any sections Entitled
+     “Acknowledgements”, and any sections Entitled “Dedications”.  You
+     must delete all sections Entitled “Endorsements.”
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the documents
+     in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow this
+     License in all other respects regarding verbatim copying of that
+     document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of a
+     storage or distribution medium, is called an “aggregate” if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation’s users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document’s Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled “Acknowledgements”,
+     “Dedications”, or “History”, the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided under this License.  Any attempt
+     otherwise to copy, modify, sublicense, or distribute it is void,
+     and will automatically terminate your rights under this License.
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly and
+     finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from you
+     under this License.  If your rights have been terminated and not
+     permanently reinstated, receipt of a copy of some or all of the
+     same material does not give you any rights to use it.
+
+  10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     <https://www.gnu.org/licenses/>.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License “or any later version” applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If the
+     Document does not specify a version number of this License, you may
+     choose any version ever published (not as a draft) by the Free
+     Software Foundation.  If the Document specifies that a proxy can
+     decide which future versions of this License can be used, that
+     proxy’s public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Document.
+
+  11. RELICENSING
+
+     “Massive Multiauthor Collaboration Site” (or “MMC Site”) means any
+     World Wide Web server that publishes copyrightable works and also
+     provides prominent facilities for anybody to edit those works.  A
+     public wiki that anybody can edit is an example of such a server.
+     A “Massive Multiauthor Collaboration” (or “MMC”) contained in the
+     site means any set of copyrightable works thus published on the MMC
+     site.
+
+     “CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0
+     license published by Creative Commons Corporation, a not-for-profit
+     corporation with a principal place of business in San Francisco,
+     California, as well as future copyleft versions of that license
+     published by that same organization.
+
+     “Incorporate” means to publish or republish a Document, in whole or
+     in part, as part of another Document.
+
+     An MMC is “eligible for relicensing” if it is licensed under this
+     License, and if all works that were first published under this
+     License somewhere other than this MMC, and subsequently
+     incorporated in whole or in part into the MMC, (1) had no cover
+     texts or invariant sections, and (2) were thus incorporated prior
+     to November 1, 2008.
+
+     The operator of an MMC Site may republish an MMC contained in the
+     site under CC-BY-SA on the same site at any time before August 1,
+     2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.3
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the “with...Texts.” line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+
+GNU @code{m4} is an implementation of the traditional UNIX macro
+processor.  It is mostly SVR4 compatible, although it has some
+extensions (for example, handling more than 9 positional parameters
+to macros).  @code{m4} also has builtin functions for including
+files, running shell commands, doing arithmetic, etc.  Autoconf needs
+GNU @code{m4} for generating @file{configure} scripts, but not for
+running them.
+
+GNU @code{m4} was originally written by Ren@'e Seindal, with
+subsequent changes by Fran@,{c}ois Pinard and other volunteers
+on the Internet.  All names and email addresses can be found in the
+files @file{m4-@value{VERSION}/@/AUTHORS} and
+@file{m4-@value{VERSION}/@/THANKS} from the GNU M4
+distribution.
+
+This is release @value{VERSION}.  It is now considered stable:  future
+releases in the 1.4.x series are only meant to fix bugs, increase speed,
+or improve documentation.  However@dots{}
+
+An experimental feature, which would improve @code{m4} usefulness,
+allows for changing the syntax for what is a @dfn{word} in @code{m4}.
+You should use:
+@comment ignore
+@example
+./configure --enable-changeword
+@end example
+@noindent
+if you want this feature compiled in.  The current implementation
+slows down @code{m4} considerably and is hardly acceptable.  In the
+future, @code{m4} 2.0 will come with a different set of new features
+that provide similar capabilities, but without the inefficiencies, so
+changeword will go away and @emph{you should not count on it}.

+@node Intro
+@section Introduction to @code{m4}
+
+@cindex overview of @code{m4}
+@code{m4} is a macro processor, in the sense that it copies its
+input to the output, expanding macros as it goes.  Macros are either
+builtin or user-defined, and can take any number of arguments.
+Besides just doing macro expansion, @code{m4} has builtin functions
+for including named files, running shell commands, doing integer
+arithmetic, manipulating text in various ways, performing recursion,
+etc.@dots{}  @code{m4} can be used either as a front-end to a compiler,
+or as a macro processor in its own right.
+
+The @code{m4} macro processor is widely available on all UNIXes, and has
+been standardized by POSIX.
+Usually, only a small percentage of users are aware of its existence.
+However, those who find it often become committed users.  The
+popularity of GNU Autoconf, which requires GNU
+@code{m4} for @emph{generating} @file{configure} scripts, is an incentive
+for many to install it, while these people will not themselves
+program in @code{m4}.  GNU @code{m4} is mostly compatible with the
+System V, Release 4 version, except for some minor differences.
+@xref{Compatibility}, for more details.
+
+Some people find @code{m4} to be fairly addictive.  They first use
+@code{m4} for simple problems, then take bigger and bigger challenges,
+learning how to write complex sets of @code{m4} macros along the way.
+Once really addicted, users pursue writing of sophisticated @code{m4}
+applications even to solve simple problems, devoting more time
+debugging their @code{m4} scripts than doing real work.  Beware that
+@code{m4} may be dangerous for the health of compulsive programmers.
+
+@node History
+@section Historical references
+
+@cindex history of @code{m4}
+@cindex GNU M4, history of
+Macro languages were invented early in the history of computing.  In the
+1950s Alan Perlis suggested that the macro language be independent of the
+language being processed.  Techniques such as conditional and recursive
+macros, and using macros to define other macros, were described by Doug
+McIlroy of Bell Labs in ``Macro Instruction Extensions of Compiler
+Languages'', @emph{Communications of the ACM} 3, 4 (1960), 214--20,
+@url{https://dl.acm.org/doi/10.1145/367177.367223}.
+
+An important precursor of @code{m4} was GPM; see C. Strachey,
+@c The title uses lower case and has no space between "macro" and "generator".
+``A general purpose macrogenerator'', @emph{Computer Journal} 8, 3
+(1965), 225--41,
+@url{https://academic.oup.com/comjnl/article/8/3/225/336044}.  GPM is
+also succinctly described in David Gries's book @emph{Compiler
+Construction for Digital Computers}, Wiley (1971).  Strachey was a
+brilliant programmer: GPM fit into 250 machine instructions!
+
+Inspired by GPM while visiting Strachey's Lab in 1968, McIlroy wrote a
+model preprocessor in that fit into a page of Snobol 3 code, and McIlroy
+and Robert Morris developed a series of further models at Bell Labs.
+Andrew D. Hall followed up with M6, a general purpose macro processor
+used to port the Fortran source code of the Altran computer algebra
+system; see Hall's ``The M6 Macro Processor'', Computing Science
+Technical Report #2, Bell Labs (1972),
+@url{http://cm.bell-labs.com/cm/cs/cstr/2.pdf}.  M6's source code
+consisted of about 600 Fortran statements.  Its name was the first of
+the @code{m4} line.
+
+The Brian Kernighan and P.J. Plauger book @emph{Software Tools},
+Addison-Wesley (1976), describes and implements a Unix
+macro-processor language, which inspired Dennis Ritchie to write
+@code{m3}, a macro processor for the AP-3 minicomputer.
+
+Kernighan and Ritchie then joined forces to develop the original
+@code{m4}, described in ``The M4 Macro Processor'', Bell Laboratories
+(1977), @url{https://wolfram.schneider.org/bsd/7thEdManVol2/m4/m4.pdf}.
+It had only 21 builtin macros.
+
+While @code{GPM} was more @emph{pure}, @code{m4} is meant to deal with
+the true intricacies of real life: macros can be recognized without
+being pre-announced, skipping whitespace or end-of-lines is easier,
+more constructs are builtin instead of derived, etc.
+
+Originally, the Kernighan and Plauger macro-processor, and then
+@code{m3}, formed the engine for the Rational FORTRAN preprocessor,
+that is, the @code{Ratfor} equivalent of @code{cpp}.  Later, @code{m4}
+was used as a front-end for @code{Ratfor}, @code{C} and @code{Cobol}.
+
+Ren@'e Seindal released his implementation of @code{m4}, GNU
+@code{m4},
+in 1990, with the aim of removing the artificial limitations in many
+of the traditional @code{m4} implementations, such as maximum line
+length, macro size, or number of macros.
+
+The late Professor A. Dain Samples described and implemented a further
+evolution in the form of @code{M5}: ``User's Guide to the M5 Macro
+Language: 2nd edition'', Electronic Announcement on comp.compilers
+newsgroup (1992).
+
+Fran@,{c}ois Pinard took over maintenance of GNU @code{m4} in
+1992, until 1994 when he released GNU @code{m4} 1.4, which was
+the stable release for 10 years.  It was at this time that GNU
+Autoconf decided to require GNU @code{m4} as its underlying
+engine, since all other implementations of @code{m4} had too many
+limitations.
+
+More recently, in 2004, Paul Eggert released 1.4.1 and 1.4.2 which
+addressed some long standing bugs in the venerable 1.4 release.  Then in
+2005, Gary V. Vaughan collected together the many patches to
+GNU @code{m4} 1.4 that were floating around the net and
+released 1.4.3 and 1.4.4.  And in 2006, Eric Blake joined the team and
+prepared patches for the release of 1.4.5, with subsequent releases
+through intervening years, as recent as 1.4.18 in 2016.
+
+Meanwhile, development has continued on new features for @code{m4}, such
+as dynamic module loading and additional builtins.  When complete,
+GNU @code{m4} 2.0 will start a new series of releases.

+@node Bugs
+@section Problems and bugs
+
+@cindex reporting bugs
+@cindex bug reports
+@cindex suggestions, reporting
+If you have problems with GNU M4 or think you've found a bug,
+please report it.  Before reporting a bug, make sure you've actually
+found a real bug.  Carefully reread the documentation and see if it
+really says you can do what you're trying to do.  If it's not clear
+whether you should be able to do something or not, report that too; it's
+a bug in the documentation!
+
+Before reporting a bug or trying to fix it yourself, try to isolate it
+to the smallest possible input file that reproduces the problem.  Then
+send us the input file and the exact results @code{m4} gave you.  Also
+say what you expected to occur; this will help us decide whether the
+problem was really in the documentation.
+
+Once you've got a precise problem, send e-mail to
+@email{bug-m4@@gnu.org}.  Please include the version number of @code{m4}
+you are using.  You can get this information with the command
+@kbd{m4 --version}.  Also provide details about the platform you are
+executing on.
+
+Non-bug suggestions are always welcome as well.  If you have questions
+about things that are unclear in the documentation or are just obscure
+features, please report them too.
+
+@node Manual
+@section Using this manual
+
+@cindex examples, understanding
+This manual contains a number of examples of @code{m4} input and output,
+and a simple notation is used to distinguish input, output and error
+messages from @code{m4}.  Examples are set out from the normal text, and
+shown in a fixed width font, like this
+
+@comment ignore
+@example
+This is an example of an example!
+@end example
+
+To distinguish input from output, all output from @code{m4} is prefixed
+by the string @samp{@result{}}, and all error messages by the string
+@samp{@error{}}.  When showing how command line options affect matters,
+the command line is shown with a prompt @samp{$ @kbd{like this}},
+otherwise, you can assume that a simple @kbd{m4} invocation will work.
+Thus:
+
+@comment ignore
+@example
+$ @kbd{command line to invoke m4}
+Example of input line
+@result{}Output line from m4
+@error{}and an error message
+@end example
+
+The sequence @samp{^D} in an example indicates the end of the input
+file.  The sequence @samp{@key{NL}} refers to the newline character.
+The majority of these examples are self-contained, and you can run them
+with similar results by invoking @kbd{m4 -d}.  In fact, the testsuite
+that is bundled in the GNU M4 package consists of the examples
+in this document!  Some of the examples assume that your current
+directory is located where you unpacked the installation, so if you plan
+on following along, you may find it helpful to do this now:
+
+@comment ignore
+@example
+$ @kbd{cd m4-@value{VERSION}}
+@end example
+
+As each of the predefined macros in @code{m4} is described, a prototype
+call of the macro will be shown, giving descriptive names to the
+arguments, e.g.,
+
+@deffn Composite example (@var{string}, @dvar{count, 1}, @
+  @ovar{argument}@dots{})
+This is a sample prototype.  There is not really a macro named
+@code{example}, but this documents that if there were, it would be a
+Composite macro, rather than a Builtin.  It requires at least one
+argument, @var{string}.  Remember that in @code{m4}, there must not be a
+space between the macro name and the opening parenthesis, unless it was
+intended to call the macro without any arguments.  The brackets around
+@var{count} and @var{argument} show that these arguments are optional.
+If @var{count} is omitted, the macro behaves as if count were @samp{1},
+whereas if @var{argument} is omitted, the macro behaves as if it were
+the empty string.  A blank argument is not the same as an omitted
+argument.  For example, @samp{example(`a')}, @samp{example(`a',`1')},
+and @samp{example(`a',`1',)} would behave identically with @var{count}
+set to @samp{1}; while @samp{example(`a',)} and @samp{example(`a',`')}
+would explicitly pass the empty string for @var{count}.  The ellipses
+(@samp{@dots{}}) show that the macro processes additional arguments
+after @var{argument}, rather than ignoring them.
+@end deffn
+
+@cindex numbers
+All macro arguments in @code{m4} are strings, but some are given
+special interpretation, e.g., as numbers, file names, regular
+expressions, etc.  The documentation for each macro will state how the
+parameters are interpreted, and what happens if the argument cannot be
+parsed according to the desired interpretation.  Unless specified
+otherwise, a parameter specified to be a number is parsed as a decimal,
+even if the argument has leading zeros; and parsing the empty string as
+a number results in 0 rather than an error, although a warning will be
+issued.
+
+This document consistently writes and uses @dfn{builtin}, without a
+hyphen, as if it were an English word.  This is how the @code{builtin}
+primitive is spelled within @code{m4}.
+
+@node Invoking m4
+@chapter Invoking @code{m4}
+
+@cindex command line
+@cindex invoking @code{m4}
+The format of the @code{m4} command is:
+
+@comment ignore
+@example
+@code{m4} @r{}@var{option}@dots{}@r{} @r{}@var{file}@dots{}@r{}
+@end example
+
+@cindex command line, options
+@cindex options, command line
+@cindex @env{POSIXLY_CORRECT}
+All options begin with @samp{-}, or if long option names are used, with
+@samp{--}.  A long option name need not be written completely, any
+unambiguous prefix is sufficient.  POSIX requires @code{m4} to
+recognize arguments intermixed with files, even when
+@env{POSIXLY_CORRECT} is set in the environment.  Most options take
+effect at startup regardless of their position, but some are documented
+below as taking effect after any files that occurred earlier in the
+command line.  The argument @option{--} is a marker to denote the end of
+options.
+
+With short options, options that do not take arguments may be combined
+into a single command line argument with subsequent options, options
+with mandatory arguments may be provided either as a single command line
+argument or as two arguments, and options with optional arguments must
+be provided as a single argument.  In other words,
+@kbd{m4 -QPDfoo -d a -df} is equivalent to
+@kbd{m4 -Q -P -D foo -d -df -- ./a}, although the latter form is
+considered canonical.
+
+With long options, options with mandatory arguments may be provided with
+an equal sign (@samp{=}) in a single argument, or as two arguments, and
+options with optional arguments must be provided as a single argument.
+In other words, @kbd{m4 --def foo --debug a} is equivalent to
+@kbd{m4 --define=foo --debug= -- ./a}, although the latter form is
+considered canonical (not to mention more robust, in case a future
+version of @code{m4} introduces an option named @option{--default}).
+
+@code{m4} understands the following options, grouped by functionality.

+
+@node Operation modes
+@section Command line options for operation modes
+
+Several options control the overall operation of @code{m4}:
+
+@table @code
+@item --help
+Print a help summary on standard output, then immediately exit
+@code{m4} without reading any input files or performing any other
+actions.
+
+@item --version
+Print the version number of the program on standard output, then
+immediately exit @code{m4} without reading any input files or
+performing any other actions.
+
+@item -E
+@itemx --fatal-warnings
+@cindex errors, fatal
+@cindex fatal errors
+Controls the effect of warnings.  If unspecified, then execution
+continues and exit status is unaffected when a warning is printed.  If
+specified exactly once, warnings become fatal; when one is issued,
+execution continues, but the exit status will be non-zero.  If specified
+multiple times, then execution halts with non-zero status the first time
+a warning is issued.  The introduction of behavior levels is new to M4
+1.4.9; for behavior consistent with earlier versions, you should specify
+@option{-E} twice.
+
+@item -i
+@itemx --interactive
+@itemx -e
+Makes this invocation of @code{m4} interactive.  This means that all
+output will be unbuffered, and interrupts will be ignored.  The
+spelling @option{-e} exists for compatibility with other @code{m4}
+implementations, and issues a warning because it may be withdrawn in a
+future version of GNU M4.
+
+@item -P
+@itemx --prefix-builtins
+Internally modify @emph{all} builtin macro names so they all start with
+the prefix @samp{m4_}.  For example, using this option, one should write
+@samp{m4_define} instead of @samp{define}, and @samp{m4___file__}
+instead of @samp{__file__}.  This option has no effect if @option{-R}
+is also specified.
+
+@item -Q
+@itemx --quiet
+@itemx --silent
+Suppress warnings, such as missing or superfluous arguments in macro
+calls, or treating the empty string as zero.
+
+@item --warn-macro-sequence@r{}=@var{regexp}@r{}
+Issue a warning if the regular expression @var{regexp} has a non-empty
+match in any macro definition (either by @code{define} or
+@code{pushdef}).  Empty matches are ignored; therefore, supplying the
+empty string as @var{regexp} disables any warning.  If the optional
+@var{regexp} is not supplied, then the default regular expression is
+@samp{\$$@{^@}*@}\|0-90-9+$} (a literal @samp{$} followed by
+multiple digits or by an open brace), since these sequences will
+change semantics in the default operation of GNU M4 2.0 (due
+to a change in how more than 9 arguments in a macro definition will be
+handled, @pxref{Arguments}).  Providing an alternate regular
+expression can provide a useful reverse lookup feature of finding
+where a macro is defined to have a given definition.
+
+@item -W @var{regexp}
+@itemx --word-regexp=@var{regexp}
+Use @var{regexp} as an alternative syntax for macro names.  This
+experimental option will not be present in all GNU @code{m4}
+implementations (@pxref{Changeword}).
+@end table
+
+@node Preprocessor features
+@section Command line options for preprocessor features
+
+@cindex macro definitions, on the command line
+@cindex command line, macro definitions on the
+@cindex preprocessor features
+Several options allow @code{m4} to behave more like a preprocessor.
+Macro definitions and deletions can be made on the command line, the
+search path can be altered, and the output file can track where the
+input came from.  These features occur with the following options:
+
+@table @code
+@item -D @var{name}@r{}=@var{value}@r{}
+@itemx --define=@var{name}@r{}=@var{value}@r{}
+This enters @var{name} into the symbol table.  If @samp{=@var{value}} is
+missing, the value is taken to be the empty string.  The @var{value} can
+be any string, and the macro can be defined to take arguments, just as
+if it was defined from within the input.  This option may be given more
+than once; order with respect to file names is significant, and
+redefining the same @var{name} loses the previous value.
+
+@item -I @var{directory}
+@itemx --include=@var{directory}
+Make @code{m4} search @var{directory} for included files that are not
+found in the current working directory.  @xref{Search Path}, for more
+details.  This option may be given more than once.
+
+@item -s
+@itemx --synclines
+@cindex synchronization lines
+@cindex location, input
+@cindex input location
+Generate synchronization lines, for use by the C preprocessor or other
+similar tools.  Order is significant with respect to file names.  This
+option is useful, for example, when @code{m4} is used as a
+front end to a compiler.  Source file name and line number information
+is conveyed by directives of the form @samp{#line @var{linenum}
+"@var{file}"}, which are inserted as needed into the middle of the
+output.  Such directives mean that the following line originated or was
+expanded from the contents of input file @var{file} at line
+@var{linenum}.  The @samp{"@var{file}"} part is often omitted when
+the file name did not change from the previous directive.
+
+Synchronization directives are always given on complete lines by
+themselves.  When a synchronization discrepancy occurs in the middle of
+an output line, the associated synchronization directive is delayed
+until the next newline that does not occur in the middle of a quoted
+string or comment.
+
+@comment options: -s
+@example
+define(`twoline', `1
+2')
+@result{}#line 2 "stdin"
+@result{}
+changecom(`/*', `*/')
+@result{}
+define(`comment', `/*1
+2*/')
+@result{}#line 5
+@result{}
+dnl no line
+hello
+@result{}#line 7
+@result{}hello
+twoline
+@result{}1
+@result{}#line 8
+@result{}2

+one comment `two
+three'
+@result{}#line 10
+@result{}one /*1
+@result{}2*/ two
+@result{}three
+goodbye
+@result{}#line 12
+@result{}goodbye
+@end example
+
+@item -U @var{name}
+@itemx --undefine=@var{name}
+This deletes any predefined meaning @var{name} might have.  Obviously,
+only predefined macros can be deleted in this way.  This option may be
+given more than once; undefining a @var{name} that does not have a
+definition is silently ignored.  Order is significant with respect to
+file names.
+@end table
+
+@node Limits control
+@section Command line options for limits control
+
+There are some limits within @code{m4} that can be tuned.  For
+compatibility, @code{m4} also accepts some options that control limits
+in other implementations, but which are automatically unbounded (limited
+only by your hardware and operating system constraints) in GNU
+@code{m4}.
+
+@table @code
+@item -g
+@itemx --gnu
+Enable all the extensions in this implementation.  In this release of
+M4, this option is always on by default; it is currently only useful
+when overriding a prior use of @option{--traditional}.  However, having
+GNU behavior as default makes it impossible to write a
+strictly POSIX-compliant client that avoids all incompatible
+GNU M4 extensions, since such a client would have to use the
+non-POSIX command-line option to force full POSIX
+behavior.  Thus, a future version of M4 will be changed to implicitly
+use the option @option{--traditional} if the environment variable
+@env{POSIXLY_CORRECT} is set.  Projects that intentionally use
+GNU extensions should consider using @option{--gnu} to state
+their intentions, so that the project will not mysteriously break if the
+user upgrades to a newer M4 and has @env{POSIXLY_CORRECT} set in their
+environment.
+
+@item -G
+@itemx --traditional
+Suppress all the extensions made in this implementation, compared to the
+System V version.  @xref{Compatibility}, for a list of these.
+
+@item -H @var{num}
+@itemx --hashsize=@var{num}
+Make the internal hash table for symbol lookup be @var{num} entries big.
+For better performance, the number should be prime, but this is not
+checked.  The default is 65537 entries.  It should not be necessary to
+increase this value, unless you define an excessive number of macros.
+
+@item -L @var{num}
+@itemx --nesting-limit=@var{num}
+@cindex nesting limit
+@cindex limit, nesting
+Artificially limit the nesting of macro calls to @var{num} levels,
+stopping program execution if this limit is ever exceeded.  When not
+specified, nesting defaults to unlimited on platforms that can detect
+stack overflow, and to 1024 levels otherwise.  A value of zero means
+unlimited; but then heavily nested code could potentially cause a stack
+overflow.
+
+The precise effect of this option is more correctly associated
+with textual nesting than dynamic recursion.  It has been useful
+when some complex @code{m4} input was generated by mechanical means, and
+also in diagnosing recursive algorithms that do not scale well.
+Most users never need to change this option from its default.
+
+@cindex rescanning
+This option does @emph{not} have the ability to break endless
+rescanning loops, since these do not necessarily consume much memory
+or stack space.  Through clever usage of rescanning loops, one can
+request complex, time-consuming computations from @code{m4} with useful
+results.  Putting limitations in this area would break @code{m4} power.
+There are many pathological cases: @w{@samp{define(`a', `a')a}} is
+only the simplest example (but @pxref{Compatibility}).  Expecting GNU
+@code{m4} to detect these would be a little like expecting a compiler
+system to detect and diagnose endless loops: it is a quite @emph{hard}
+problem in general, if not undecidable!
+
+@item -B @var{num}
+@itemx -S @var{num}
+@itemx -T @var{num}
+These options are present for compatibility with System V @code{m4}, but
+do nothing in this implementation.  They may disappear in future
+releases, and issue a warning to that effect.
+
+@item -N @var{num}
+@itemx --diversions=@var{num}
+These options are present only for compatibility with previous
+versions of GNU @code{m4}, and were controlling the number of
+possible diversions which could be used at the same time.  They do nothing,
+because there is no fixed limit anymore.  They may disappear in future
+releases, and issue a warning to that effect.

+@node Frozen state
+@section Command line options for frozen state

+
+@item --debugfile@r{}=@var{file}@r{}
+@itemx -o @var{file}
+@itemx --error-output=@var{file}
+Redirect @code{dumpdef} output, debug messages, and trace output to the
+named @var{file}.  Warnings, error messages, and @code{errprint} output
+are still printed to standard error.  If these options are not used, or
+if @var{file} is unspecified (only possible for @option{--debugfile}),
+debug output goes to standard error; if @var{file} is the empty string,
+debug output is discarded.  @xref{Debug Output}, for more details.  The
+option @option{--debugfile} may be given more than once, and order is
+significant with respect to file names.  The spellings @option{-o} and
+@option{--error-output} are misleading and inconsistent with other
+GNU tools; for now they are silently accepted as synonyms of

+@node Command line files
+@section Specifying input files on the command line
+
+@cindex command line, file names on the
+@cindex file names, on the command line
+The remaining arguments on the command line are taken to be input file
+names.  If no names are present, standard input is read.  A file
+name of @file{-} is taken to mean standard input.  It is
+conventional, but not required, for input files to end in @samp{.m4}.
+
+The input files are read in the sequence given.  Standard input can be
+read more than once, so the file name @file{-} may appear multiple times
+on the command line; this makes a difference when input is from a
+terminal or other special file type.  It is an error if an input file
+ends in the middle of argument collection, a comment, or a quoted

+
+The options @option{--define} (@option{-D}), @option{--undefine}
+(@option{-U}), @option{--synclines} (@option{-s}), and @option{--trace}
+(@option{-t}) only take effect after processing input from any file
+names that occur earlier on the command line.  For example, assume the
+file @file{foo} contains:
+
+@comment ignore
+@example
+$ @kbd{cat foo}
+bar
+@end example
+
+The text @samp{bar} can then be redefined over multiple uses of

+If none of the input files invoked @code{m4exit} (@pxref{M4exit}), the
+exit status of @code{m4} will be 0 for success, 1 for general failure
+(such as problems with reading an input file), and 63 for version
+mismatch (@pxref{Using frozen files}).

+specify it as @samp{./-file}, or use @option{--} to mark the end of

+@cindex input tokens
+@cindex tokens
+As @code{m4} reads its input, it separates it into @dfn{tokens}.  A
+token is either a name, a quoted string, or any single character, that
+is not a part of either a name or a string.  Input to @code{m4} can also
+contain comments.  GNU @code{m4} does not yet understand
+multibyte locales; all operations are byte-oriented rather than
+character-oriented (although if your locale uses a single byte
+encoding, such as @sc{ISO-8859-1}, you will not notice a difference).
+However, @code{m4} is eight-bit clean, so you can
+use non-@sc{ascii} characters in quoted strings (@pxref{Changequote}),
+comments (@pxref{Changecom}), and macro names (@pxref{Indir}), with the
+exception of the @sc{nul} character (the zero byte @samp{'\0'}).

+@node Names
+@section Macro names
+
+@cindex names
+@cindex words
+A name is any sequence of letters, digits, and the character @samp{_}
+(underscore), where the first character is not a digit.  @code{m4} will
+use the longest such sequence found in the input.  If a name has a
+macro definition, it will be subject to macro expansion
+(@pxref{Macros}).  Names are case-sensitive.
+
+Examples of legal names are: @samp{foo}, @samp{_tmp}, and @samp{name01}.
+
+@node Quoted strings
+@section Quoting input to @code{m4}
+
+@cindex quoted string
+@cindex string, quoted
+A quoted string is a sequence of characters surrounded by quote
+strings, defaulting to
+@samp{`} and @samp{'}, where the nested begin and end quotes within the
+string are balanced.  The value of a string token is the text, with one
+level of quotes stripped off.  Thus
+
+@comment ignore
+@example
+`'
+@result{}
+@end example
+
+@noindent
+is the empty string, and double-quoting turns into single-quoting.
+
+@comment ignore
+@example
+``quoted''
+@result{}`quoted'
+@end example
+
+The quote characters can be changed at any time, using the builtin macro
+@code{changequote}.  @xref{Changequote}, for more information.
+
+@node Comments
+@section Comments in @code{m4} input
+
+@cindex comments
+Comments in @code{m4} are normally delimited by the characters @samp{#}
+and newline.  All characters between the comment delimiters are ignored,
+but the entire comment (including the delimiters) is passed through to
+the output---comments are @emph{not} discarded by @code{m4}.
+
+Comments cannot be nested, so the first newline after a @samp{#} ends
+the comment.  The commenting effect of the begin-comment string
+can be inhibited by quoting it.
+
+@example
+$ @kbd{m4}
+`quoted text' # `commented text'
+@result{}quoted text # `commented text'
+`quoting inhibits' `#' `comments'
+@result{}quoting inhibits # comments

+
+@node Other tokens
+@section Other kinds of input tokens
+
+@cindex tokens, special
+Any character, that is neither a part of a name, nor of a quoted string,
+nor a comment, is a token by itself.  When not in the context of macro
+expansion, all of these tokens are just copied to output.  However,
+during macro expansion, whitespace characters (space, tab, newline,
+formfeed, carriage return, vertical tab), parentheses (@samp{(} and
+@samp{)}), comma (@samp{,}), and dollar (@samp{$}) have additional
+roles, explained later.
+
+@node Input processing
+@section How @code{m4} copies input to output
+
+As @code{m4} reads the input token by token, it will copy each token
+directly to the output immediately.
+
+The exception is when it finds a word with a macro definition.  In that
+case @code{m4} will calculate the macro's expansion, possibly reading
+more input to get the arguments.  It then inserts the expansion in front
+of the remaining input.  In other words, the resulting text from a macro
+call will be read and parsed into tokens again.
+
+@code{m4} expands a macro as soon as possible.  If it finds a macro call
+when collecting the arguments to another, it will expand the second call
+first.  This process continues until there are no more macro calls to
+expand and all the input has been consumed.
+
+For a running example, examine how @code{m4} handles this input:
+
+@comment ignore
+@example
+format(`Result is %d', eval(`2**15'))
+@end example
+
+@noindent
+First, @code{m4} sees that the token @samp{format} is a macro name, so
+it collects the tokens @samp{(}, @samp{`Result is %d'}, @samp{,},
+and @samp{@w{ }}, before encountering another potential macro.  Sure
+enough, @samp{eval} is a macro name, so the nested argument collection
+picks up @samp{(}, @samp{`2**15'}, and @samp{)}, invoking the eval macro
+with the lone argument of @samp{2**15}.  The expansion of
+@samp{eval(2**15)} is @samp{32768}, which is then rescanned as the five
+tokens @samp{3}, @samp{2}, @samp{7}, @samp{6}, and @samp{8}; and
+combined with the next @samp{)}, the format macro now has all its
+arguments, as if the user had typed:
+
+@comment ignore
+@example
+format(`Result is %d', 32768)
+@end example
+
+@noindent
+The format macro expands to @samp{Result is 32768}, and we have another
+round of scanning for the tokens @samp{Result}, @samp{@w{ }},
+@samp{is}, @samp{@w{ }}, @samp{3}, @samp{2}, @samp{7}, @samp{6}, and
+@samp{8}.  None of these are macros, so the final output is
+
+@comment ignore
+@example
+@result{}Result is 32768
+@end example
+
+As a more complicated example, we will contrast an actual code
+example from the Gnulib project@footnote{Derived from a patch in
+@uref{https://lists.gnu.org/archive/html/bug-gnulib/@/2007-01/@/msg00389.html},
+and a followup patch in
+@uref{https://lists.gnu.org/archive/html/bug-gnulib/@/2007-02/@/msg00000.html}},
+showing both a buggy approach and the desired results.  The user desires
+to output a shell assignment statement that takes its argument and turns
+it into a shell variable by converting it to uppercase and prepending a
+prefix.  The original attempt looks like this:
+
+@example
+changequote(,)dnl
+define(gl_STRING_MODULE_INDICATOR,
+  
+    dnl comment
+    GNULIB_translit($1,a-z,A-Z)=1
+  )dnl
+  gl_STRING_MODULE_INDICATOR(strcase)
+@result{} @w{ }
+@result{}        GNULIB_strcase=1
+@result{} @w{ }
+@end example
+
+Oops -- the argument did not get capitalized.  And although the manual
+is not able to easily show it, both lines that appear empty actually
+contain two trailing spaces.  By stepping through the parse, it is easy
+to see what happened.  First, @code{m4} sees the token
+@samp{changequote}, which it recognizes as a macro, followed by
+@samp{(}, @samp{}, @samp{,}, @samp{}, and @samp{)} to form the
+argument list.  The macro expands to the empty string, but changes the
+quoting characters to something more useful for generating shell code
+(unbalanced @samp{`} and @samp{'} appear all the time in shell scripts,
+but unbalanced @samp{} tend to be rare).  Also in the first line,
+@code{m4} sees the token @samp{dnl}, which it recognizes as a builtin
+macro that consumes the rest of the line, resulting in no output for
+that line.
+
+The second line starts a macro definition.  @code{m4} sees the token
+@samp{define}, which it recognizes as a macro, followed by a @samp{(},
+@samp{gl_STRING_MODULE_INDICATOR}, and @samp{,}.  Because an unquoted
+comma was encountered, the first argument is known to be the expansion
+of the single-quoted string token, or @samp{gl_STRING_MODULE_INDICATOR}.
+Next, @code{m4} sees @samp{@key{NL}}, @samp{ }, and @samp{ }, but this
+whitespace is discarded as part of argument collection.  Then comes a
+rather lengthy single-quoted string token, @samp{@key{NL}@ @ @ @ dnl
+comment@key{NL}@ @ @ @ GNULIB_}.  This is followed by the token
+@samp{translit}, which @code{m4} recognizes as a macro name, so a nested
+macro expansion has started.
+
+The arguments to the @code{translit} are found by the tokens @samp{(},
+@samp{$1}, @samp{,}, @samp{a-z}, @samp{,}, @samp{A-Z}, and finally
+@samp{)}.  All three string arguments are expanded (or in other words,
+the quotes are stripped), and since neither @samp{$} nor @samp{1} need
+capitalization, the result of the macro is @samp{$1}.  This expansion is
+rescanned, resulting in the two literal characters @samp{$} and
+@samp{1}.
+
+Scanning of the outer macro resumes, and picks up with
+@samp{=1@key{NL}@ @ }, and finally @samp{)}.  The collected pieces of
+expanded text are concatenated, with the end result that the macro
+@samp{gl_STRING_MODULE_INDICATOR} is now defined to be the sequence
+@samp{@key{NL}@ @ @ @ dnl comment@key{NL}@ @ @ @ GNULIB_$1=1@key{NL}@ @ }.
+Once again, @samp{dnl} is recognized and avoids a newline in the output.
+
+The final line is then parsed, beginning with @samp{ } and @samp{ }
+that are output literally.  Then @samp{gl_STRING_MODULE_INDICATOR} is
+recognized as a macro name, with an argument list of @samp{(},
+@samp{strcase}, and @samp{)}.  Since the definition of the macro
+contains the sequence @samp{$1}, that sequence is replaced with the
+argument @samp{strcase} prior to starting the rescan.  The rescan sees
+@samp{@key{NL}} and four spaces, which are output literally, then
+@samp{dnl}, which discards the text @samp{ comment@key{NL}}.  Next
+comes four more spaces, also output literally, and the token
+@samp{GNULIB_strcase}, which resulted from the earlier parameter
+substitution.  Since that is not a macro name, it is output literally,
+followed by the literal tokens @samp{=}, @samp{1}, @samp{@key{NL}}, and
+two more spaces.  Finally, the original @samp{@key{NL}} seen after the
+macro invocation is scanned and output literally.
+
+Now for a corrected approach.  This rearranges the use of newlines and
+whitespace so that less whitespace is output (which, although harmless
+to shell scripts, can be visually unappealing), and fixes the quoting
+issues so that the capitalization occurs when the macro
+@samp{gl_STRING_MODULE_INDICATOR} is invoked, rather then when it is
+defined.  It also adds another layer of quoting to the first argument of
+@code{translit}, to ensure that the output will be rescanned as a string
+rather than a potential uppercase macro name needing further expansion.
+
+@example
+changequote(,)dnl
+define(gl_STRING_MODULE_INDICATOR,
+  dnl comment
+  GNULIB_translit($1, a-z, A-Z)=1dnl
+)dnl
+  gl_STRING_MODULE_INDICATOR(strcase)
+@result{}    GNULIB_STRCASE=1
+@end example
+
+The parsing of the first line is unchanged.  The second line sees the
+name of the macro to define, then sees the discarded @samp{@key{NL}}
+and two spaces, as before.  But this time, the next token is
+@samp{dnl comment@key{NL}@ @ GNULIB_translit($1, a-z,
+A-Z)=1dnl@key{NL}}, which includes nested quotes, followed by
+@samp{)} to end the macro definition and @samp{dnl} to skip the
+newline.  No early expansion of @code{translit} occurs, so the entire
+string becomes the definition of the macro.
+
+The final line is then parsed, beginning with two spaces that are
+output literally, and an invocation of
+@code{gl_STRING_MODULE_INDICATOR} with the argument @samp{strcase}.
+Again, the @samp{$1} in the macro definition is substituted prior to
+rescanning.  Rescanning first encounters @samp{dnl}, and discards
+@samp{ comment@key{NL}}.  Then two spaces are output literally.  Next
+comes the token @samp{GNULIB_}, but that is not a macro, so it is
+output literally.  The token @samp{} is an empty string, so it does
+not affect output.  Then the token @samp{translit} is encountered.
+
+This time, the arguments to @code{translit} are parsed as @samp{(},
+@samp{strcase}, @samp{,}, @samp{ }, @samp{a-z}, @samp{,}, @samp{ },
+@samp{A-Z}, and @samp{)}.  The two spaces are discarded, and the
+translit results in the desired result @samp{STRCASE}.  This is
+rescanned, but since it is a string, the quotes are stripped and the
+only output is a literal @samp{STRCASE}.
+Then the scanner sees @samp{=} and @samp{1}, which are output
+literally, followed by @samp{dnl} which discards the rest of the
+definition of @code{gl_STRING_MODULE_INDICATOR}.  The newline at the
+end of output is the literal @samp{@key{NL}} that appeared after the
+invocation of the macro.
+
+The order in which @code{m4} expands the macros can be further explored
+using the trace facilities of GNU @code{m4} (@pxref{Trace}).

+
+For a macro call to have no arguments, the parentheses @emph{must} be
+left out.  The macro call
+
+@comment ignore
+@example
+name()

+
+@noindent
+is a macro call with one argument, which is the empty string, not a call
+with no arguments.
+
+@node Inhibiting Invocation
+@section Preventing macro invocation
+
+An innovation of the @code{m4} language, compared to some of its
+predecessors (like Strachey's @code{GPM}, for example), is the ability
+to recognize macro calls without resorting to any special, prefixed
+invocation character.  While generally useful, this feature might
+sometimes be the source of spurious, unwanted macro calls.  So, GNU
+@code{m4} offers several mechanisms or techniques for inhibiting the
+recognition of names as macro calls.
+
+@cindex GNU extensions
+@cindex blind macro
+@cindex macro, blind
+First of all, many builtin macros cannot meaningfully be called without
+arguments.  As a GNU extension, for any of these macros,
+whenever an opening parenthesis does not immediately follow their name,
+the builtin macro call is not triggered.  This solves the most usual
+cases, like for @samp{include} or @samp{eval}.  Later in this document,
+the sentence ``This macro is recognized only with parameters'' refers to
+this specific provision of GNU M4, also known as a blind
+builtin macro.  For the builtins defined by POSIX that bear
+this disclaimer, POSIX specifically states that invoking those
+builtins without arguments is unspecified, because many other
+implementations simply invoke the builtin as though it were given one
+empty argument instead.
+
+@example
+$ @kbd{m4}
+eval
+@result{}eval
+eval(`1')
+@result{}1
+@end example
+
+There is also a command line option (@option{--prefix-builtins}, or
+@option{-P}, @pxref{Operation modes, , Invoking m4}) that renames all
+builtin macros with a prefix of @samp{m4_} at startup.  The option has
+no effect whatsoever on user defined macros.  For example, with this option,
+one has to write @code{m4_dnl} and even @code{m4_m4exit}.  It also has
+no effect on whether a macro requires parameters.
+
+@comment options: -P
+@example
+$ @kbd{m4 -P}
+eval
+@result{}eval
+eval(`1')
+@result{}eval(1)
+m4_eval
+@result{}m4_eval
+m4_eval(`1')
+@result{}1
+@end example
+
+Another alternative is to redefine problematic macros to a name less
+likely to cause conflicts, using @ref{Definitions}.
+
+If your version of GNU @code{m4} has the @code{changeword} feature
+compiled in, it offers far more flexibility in specifying the
+syntax of macro names, both builtin or user-defined.  @xref{Changeword},
+for more information on this experimental feature.
+
+Of course, the simplest way to prevent a name from being interpreted
+as a call to an existing macro is to quote it.  The remainder of
+this section studies a little more deeply how quoting affects macro
+invocation, and how quoting can be used to inhibit macro invocation.
+
+Even if quoting is usually done over the whole macro name, it can also
+be done over only a few characters of this name (provided, of course,
+that the unquoted portions are not also a macro).  It is also possible
+to quote the empty string, but this works only @emph{inside} the name.
+For example:
+
+@example
+`divert'
+@result{}divert
+`d'ivert
+@result{}divert
+di`ver't
+@result{}divert
+div`'ert
+@result{}divert
+@end example
+
+@noindent
+all yield the string @samp{divert}.  While in both:
+
+@example
+`'divert
+@result{}
+divert`'
+@result{}
+@end example
+
+@noindent
+the @code{divert} builtin macro will be called, which expands to the
+empty string.
+
+@cindex rescanning
+The output of macro evaluations is always rescanned.  In the following
+example, the input @samp{x`'y} yields the string @samp{bCD}, exactly as
+if @code{m4}
+has been given @w{@samp{substr(ab`'cde, `1', `3')}} as input:
+
+@example
+define(`cde', `CDE')
+@result{}
+define(`x', `substr(ab')
+@result{}
+define(`y', `cde, `1', `3')')
+@result{}
+x`'y
+@result{}bCD
+@end example
+
+@ignore
+@comment Similar, but with argument references, to ensure good test
+@comment coverage.
+@example
+define(`x1', `len(`$1'')
+@result{}
+define(`y1', ``$1')')
+@result{}
+x1(`01234567890123456789')y1(`98765432109876543210')
+@result{}40
+@end example
+@end ignore
+
+Unquoted strings on either side of a quoted string are subject to
+being recognized as macro names.  In the following example, quoting the
+empty string allows for the second @code{macro} to be recognized as such:
+
+@example
+define(`macro', `m')
+@result{}
+macro(`m')macro
+@result{}mmacro
+macro(`m')`'macro
+@result{}mm
+@end example
+
+Quoting may prevent recognizing as a macro name the concatenation of a
+macro expansion with the surrounding characters.  In this example:
+
+@example
+define(`macro', `di$1')
+@result{}
+macro(`v')`ert'
+@result{}divert
+macro(`v')ert
+@result{}
+@end example
+
+@noindent
+the input will produce the string @samp{divert}.  When the quotes were
+removed, the @code{divert} builtin was called instead.
+
+@node Macro Arguments
+@section Macro arguments
+
+@cindex macros, arguments to
+@cindex arguments to macros
+When a name is seen, and it has a macro definition, it will be expanded
+as a macro.
+
+If the name is followed by an opening parenthesis, the arguments will be
+collected before the macro is called.  If too few arguments are
+supplied, the missing arguments are taken to be the empty string.
+However, some builtins are documented to behave differently for a
+missing optional argument than for an explicit empty string.  If there
+are too many arguments, the excess arguments are ignored.  Unquoted
+leading whitespace is stripped off all arguments, but whitespace
+generated by a macro expansion or occurring after a macro that expanded
+to an empty string remains intact.  Whitespace includes space, tab,
+newline, carriage return, vertical tab, and formfeed.
+
+@example
+define(`macro', `$1')
+@result{}
+macro( unquoted leading space lost)
+@result{}unquoted leading space lost
+macro(` quoted leading space kept')
+@result{} quoted leading space kept
+macro(
+ divert `unquoted space kept after expansion')
+@result{} unquoted space kept after expansion
+macro(macro(`
+')`whitespace from expansion kept')
+@result{}
+@result{}whitespace from expansion kept
+macro(`unquoted trailing whitespace kept'
+)
+@result{}unquoted trailing whitespace kept
+@result{}
+@end example
+
+@cindex warnings, suppressing
+@cindex suppressing warnings
+Normally @code{m4} will issue warnings if a builtin macro is called
+with an inappropriate number of arguments, but it can be suppressed with
+the @option{--quiet} command line option (or @option{--silent}, or
+@option{-Q}, @pxref{Operation modes, , Invoking m4}).  For user
+defined macros, there is no check of the number of arguments given.
+
+@example
+$ @kbd{m4}
+index(`abc')
+@error{}m4:stdin:1: Warning: too few arguments to builtin `index'
+@result{}0
+index(`abc',)
+@result{}0
+index(`abc', `b', `ignored')
+@error{}m4:stdin:3: Warning: excess arguments to builtin `index' ignored
+@result{}1
+@end example
+
+@comment options: -Q
+@example
+$ @kbd{m4 -Q}
+index(`abc')
+@result{}0
+index(`abc',)
+@result{}0
+index(`abc', `b', `ignored')
+@result{}1
+@end example
+
+Macros are expanded normally during argument collection, and whatever
+commas, quotes and parentheses that might show up in the resulting
+expanded text will serve to define the arguments as well.  Thus, if
+@var{foo} expands to @samp{, b, c}, the macro call
+
+@comment ignore
+@example
+bar(a foo, d)
+@end example
+
+@noindent
+is a macro call with four arguments, which are @samp{a }, @samp{b},
+@samp{c} and @samp{d}.  To understand why the first argument contains
+whitespace, remember that unquoted leading whitespace is never part
+of an argument, but trailing whitespace always is.
+
+It is possible for a macro's definition to change during argument
+collection, in which case the expansion uses the definition that was in
+effect at the time the opening @samp{(} was seen.
+
+@example
+define(`f', `1')
+@result{}
+f(define(`f', `2'))
+@result{}1
+f
+@result{}2
+@end example
+
+It is an error if the end of file occurs while collecting arguments.
+
+@comment status: 1
+@example
+hello world
+@result{}hello world
+define(
+^D
+@error{}m4:stdin:2: ERROR: end of file in argument list
+@end example
+
+@node Quoting Arguments
+@section On Quoting Arguments to macros
+
+@cindex quoted macro arguments
+@cindex macros, quoted arguments to
+@cindex arguments, quoted macro
+Each argument has unquoted leading whitespace removed.  Within each
+argument, all unquoted parentheses must match.  For example, if
+@var{foo} is a macro,
+
+@comment ignore
+@example
+foo(() (`(') `(')
+@end example
+
+@noindent
+is a macro call, with one argument, whose value is @samp{() (() (}.
+Commas separate arguments, except when they occur inside quotes,
+comments, or unquoted parentheses.  @xref{Pseudo Arguments}, for
+examples.
+
+It is common practice to quote all arguments to macros, unless you are
+sure you want the arguments expanded.  Thus, in the above
+example with the parentheses, the `right' way to do it is like this:
+
+@comment ignore
+@example
+foo(`() (() (')
+@end example
+
+@cindex quoting rule of thumb
+@cindex rule of thumb, quoting
+It is, however, in certain cases necessary (because nested expansion
+must occur to create the arguments for the outer macro) or convenient
+(because it uses fewer characters) to leave out quotes for some
+arguments, and there is nothing wrong in doing it.  It just makes life a
+bit harder, if you are not careful to follow a consistent quoting style.
+For consistency, this manual follows the rule of thumb that each layer
+of parentheses introduces another layer of single quoting, except when
+showing the consequences of quoting rules.  This is done even when the
+quoted string cannot be a macro, such as with integers when you have not
+changed the syntax via @code{changeword} (@pxref{Changeword}).
+
+The quoting rule of thumb of one level of quoting per parentheses has a
+nice property: when a macro name appears inside parentheses, you can
+determine when it will be expanded.  If it is not quoted, it will be
+expanded prior to the outer macro, so that its expansion becomes the
+argument.  If it is single-quoted, it will be expanded after the outer
+macro.  And if it is double-quoted, it will be used as literal text
+instead of a macro name.
+
+@example
+define(`active', `ACT, IVE')
+@result{}
+define(`show', `$1 $1')
+@result{}
+show(active)
+@result{}ACT ACT
+show(`active')
+@result{}ACT, IVE ACT, IVE
+show(``active'')
+@result{}active active
+@end example
+
+@node Macro expansion
+@section Macro expansion
+
+@cindex macros, expansion of
+@cindex expansion of macros
+When the arguments, if any, to a macro call have been collected, the
+macro is expanded, and the expansion text is pushed back onto the input
+(unquoted), and reread.  The expansion text from one macro call might
+therefore result in more macros being called, if the calls are included,
+completely or partially, in the first macro calls' expansion.
+
+Taking a very simple example, if @var{foo} expands to @samp{bar}, and
+@var{bar} expands to @samp{Hello}, the input
+
+@comment options: -Dbar=Hello -Dfoo=bar
+@example
+$ @kbd{m4 -Dbar=Hello -Dfoo=bar}
+foo
+@result{}Hello
+@end example
+
+@noindent
+will expand first to @samp{bar}, and when this is reread and
+expanded, into @samp{Hello}.

+@node Define
+@section Defining a macro
+
+The normal way to define or redefine macros is to use the builtin
+@code{define}:
+
+@deffn Builtin define (@var{name}, @ovar{expansion})
+Defines @var{name} to expand to @var{expansion}.  If
+@var{expansion} is not given, it is taken to be empty.
+
+The expansion of @code{define} is void.
+The macro @code{define} is recognized only with parameters.
+@end deffn
+
+The following example defines the macro @var{foo} to expand to the text
+@samp{Hello World.}.
+
+@example
+define(`foo', `Hello world.')
+@result{}
+foo
+@result{}Hello world.
+@end example
+
+The empty line in the output is there because the newline is not
+a part of the macro definition, and it is consequently copied to
+the output.  This can be avoided by use of the macro @code{dnl}.
+@xref{Dnl}, for details.
+
+The first argument to @code{define} should be quoted; otherwise, if the
+macro is already defined, you will be defining a different macro.  This
+example shows the problems with underquoting, since we did not want to
+redefine @code{one}:
+
+@example
+define(foo, one)
+@result{}
+define(foo, two)
+@result{}
+one
+@result{}two
+@end example
+
+@cindex GNU extensions
+GNU @code{m4} normally replaces only the @emph{topmost}
+definition of a macro if it has several definitions from @code{pushdef}
+(@pxref{Pushdef}).  Some other implementations of @code{m4} replace all
+definitions of a macro with @code{define}.  @xref{Incompatibilities},
+for more details.
+
+As a GNU extension, the first argument to @code{define} does
+not have to be a simple word.
+It can be any text string, even the empty string.  A macro with a
+non-standard name cannot be invoked in the normal way, as the name is
+not recognized.  It can only be referenced by the builtins @code{indir}
+(@pxref{Indir}) and @code{defn} (@pxref{Defn}).
+
+@cindex arrays
+Arrays and associative arrays can be simulated by using non-standard
+macro names.
+
+@deffn Composite array (@var{index})
+@deffnx Composite array_set (@var{index}, @ovar{value})
+Provide access to entries within an array.  @code{array} reads the entry
+at location @var{index}, and @code{array_set} assigns @var{value} to
+location @var{index}.
+@end deffn
+
+@example
+define(`array', `defn(format(``array%d'', `$1'))')
+@result{}
+define(`array_set', `define(format(``array%d'', `$1'), `$2')')
+@result{}
+array_set(`4', `array element no. 4')

+array_set(`17', `array element no. 17')
+@result{}
+array(`4')
+@result{}array element no. 4
+array(eval(`10 + 7'))
+@result{}array element no. 17

+@node Arguments
+@section Arguments to macros
+
+@cindex macros, arguments to
+@cindex arguments to macros
+Macros can have arguments.  The @var{n}th argument is denoted by
+@code{$n} in the expansion text, and is replaced by the @var{n}th actual
+argument, when the macro is expanded.  Replacement of arguments happens
+before rescanning, regardless of how many nesting levels of quoting
+appear in the expansion.  Here is an example of a macro with
+two arguments.
+
+@deffn Composite exch (@var{arg1}, @var{arg2})
+Expands to @var{arg2} followed by @var{arg1}, effectively exchanging
+their order.
+@end deffn
+
+@example
+define(`exch', `$2, $1')
+@result{}
+exch(`arg1', `arg2')
+@result{}arg2, arg1
+@end example
+
+This can be used, for example, if you like the arguments to
+@code{define} to be reversed.
+
+@example
+define(`exch', `$2, $1')
+@result{}
+define(exch(``expansion text'', ``macro''))
+@result{}
+macro
+@result{}expansion text
+@end example
+
+@xref{Quoting Arguments}, for an explanation of the double quotes.
+(You should try and improve this example so that clients of @code{exch}
+do not have to double quote; or @pxref{Improved exch, , Answers}).
+
+As a special case, the zeroth argument, @code{$0}, is always the name
+of the macro being expanded.
+
+@example
+define(`test', ``Macro name: $0'')
+@result{}
+test
+@result{}Macro name: test
+@end example
+
+If you want quoted text to appear as part of the expansion text,
+remember that quotes can be nested in quoted strings.  Thus, in
+
+@example
+define(`foo', `This is macro `foo'.')
+@result{}
+foo
+@result{}This is macro foo.
+@end example
+
+@noindent
+The @samp{foo} in the expansion text is @emph{not} expanded, since it is
+a quoted string, and not a name.
+
+@cindex GNU extensions
+@cindex nine arguments, more than
+@cindex more than nine arguments
+@cindex arguments, more than nine
+@cindex positional parameters, more than nine
+GNU @code{m4} allows the number following the @samp{$} to
+consist of one or more digits, allowing macros to have any number of
+arguments.  The extension of accepting multiple digits is incompatible
+with POSIX, and is different than traditional implementations
+of @code{m4}, which only recognize one digit.  Therefore, future
+versions of GNU M4 will phase out this feature.  To portably
+access beyond the ninth argument, you can use the @code{argn} macro
+documented later (@pxref{Shift}).
+
+POSIX also states that @samp{$} followed immediately by
+@samp{@{} in a macro definition is implementation-defined.  This version
+of M4 passes the literal characters @samp{$@{} through unchanged, but M4
+2.0 will implement an optional feature similar to @command{sh}, where
+@samp{$@{11@}} expands to the eleventh argument, to replace the current
+recognition of @samp{$11}.  Meanwhile, if you want to guarantee that you
+will get a literal @samp{$@{} in output when expanding a macro, even
+when you upgrade to M4 2.0, you can use nested quoting to your
+advantage:
+
+@example
+define(`foo', `single quoted $`'@{1@} output')
+@result{}
+define(`bar', ``double quoted $'`@{2@} output'')
+@result{}
+foo(`a', `b')
+@result{}single quoted $@{1@} output
+bar(`a', `b')
+@result{}double quoted $@{2@} output
+@end example
+
+To help you detect places in your M4 input files that might change in
+behavior due to the changed behavior of M4 2.0, you can use the
+@option{--warn-macro-sequence} command-line option (@pxref{Operation
+modes, , Invoking m4}) with the default regular expression.  This will
+add a warning any time a macro definition includes @samp{$} followed by
+multiple digits, or by @samp{@{}.  The warning is not enabled by
+default, because it triggers a number of warnings in Autoconf 2.61 (and
+Autoconf uses @option{-E} to treat warnings as errors), and because it
+will still be possible to restore older behavior in M4 2.0.
+
+@comment options: --warn-macro-sequence

+
+Remember that @samp{#} defaults to the comment character; if you forget

+
+@example
+define(`echo', `$*')
+@result{}
+echo(arg1,    arg2, arg3 , arg4)
+@result{}arg1,arg2,arg3 ,arg4
+@end example
+
+Often each argument should be quoted, and the notation @code{$@@} handles
+that.  It is just like @code{$*}, except that it quotes each argument.
+A simple example of that is:
+
+@example
+define(`echo', `$@@')
+@result{}
+echo(arg1,    arg2, arg3 , arg4)
+@result{}arg1,arg2,arg3 ,arg4

+
+Where did the quotes go?  Of course, they were eaten, when the expanded

+define(`echo2', `$@@')
+@result{}

+@result{}foo
+@end example
+
+@noindent
+@xref{Trace}, if you do not understand this.  As another example of the

+@section Renaming macros
+
+@cindex macros, how to rename
+@cindex renaming macros
+@cindex macros, displaying definitions
+@cindex definitions, displaying macro
+It is possible to rename an already defined macro.  To do this, you need
+the builtin @code{defn}:
+
+@deffn Builtin defn (@var{name}@dots{})
+Expands to the @emph{quoted definition} of each @var{name}.  If an
+argument is not a defined macro, the expansion for that argument is
+empty.
+
+If @var{name} is a user-defined macro, the quoted definition is simply
+the quoted expansion text.  If, instead, there is only one @var{name}
+and it is a builtin, the
+expansion is a special token, which points to the builtin's internal
+definition.  This token is only meaningful as the second argument to
+@code{define} (and @code{pushdef}), and is silently converted to an
+empty string in most other contexts.  Combining a builtin with anything
+else is not supported; a warning is issued and the builtin is omitted
+from the final expansion.
+
+The macro @code{defn} is recognized only with parameters.
+@end deffn
+
+Its normal use is best understood through an example, which shows how to
+rename @code{undefine} to @code{zap}:
+
+@example
+define(`zap', defn(`undefine'))
+@result{}
+zap(`undefine')
+@result{}
+undefine(`zap')
+@result{}undefine(zap)
+@end example
+
+In this way, @code{defn} can be used to copy macro definitions, and also
+definitions of builtin macros.  Even if the original macro is removed,
+the other name can still be used to access the definition.
+
+The fact that macro definitions can be transferred also explains why you
+should use @code{$0}, rather than retyping a macro's name in its
+definition:
+
+@example
+define(`foo', `This is `$0'')
+@result{}
+define(`bar', defn(`foo'))
+@result{}
+bar
+@result{}This is bar
+@end example
+
+Macros used as string variables should be referred through @code{defn},
+to avoid unwanted expansion of the text:
+
+@example
+define(`string', `The macro dnl is very useful
+')
+@result{}
+string
+@result{}The macro@w{ }
+defn(`string')
+@result{}The macro dnl is very useful
+@result{}
+@end example
+
+@cindex rescanning
+However, it is important to remember that @code{m4} rescanning is purely
+textual.  If an unbalanced end-quote string occurs in a macro
+definition, the rescan will see that embedded quote as the termination
+of the quoted string, and the remainder of the macro's definition will
+be rescanned unquoted.  Thus it is a good idea to avoid unbalanced
+end-quotes in macro definitions or arguments to macros.
+
+@example
+define(`foo', a'a)
+@result{}
+define(`a', `A')
+@result{}
+define(`echo', `$@@')
+@result{}
+foo
+@result{}A'A
+defn(`foo')
+@result{}aA'
+echo(foo)
+@result{}AA'
+@end example
+
+On the other hand, it is possible to exploit the fact that @code{defn}
+can concatenate multiple macros prior to the rescanning phase, in order
+to join the definitions of macros that, in isolation, have unbalanced
+quotes.  This is particularly useful when one has used several macros to
+accumulate text that M4 should rescan as a whole.  In the example below,
+note how the use of @code{defn} on @code{l} in isolation opens a string,
+which is not closed until the next line; but used on @code{l} and
+@code{r} together results in nested quoting.
+
+@example
+define(`l', `<>')define(`r', `<>')
+@result{}
+changequote(`', `')
+@result{}
+defn(l)defn(r)
+)
+@result{}<>defn(r)
+@result{})
+defn(l, r)
+@result{}<><>
+@end example
+
+@cindex builtins, special tokens
+@cindex tokens, builtin macro
+Using @code{defn} to generate special tokens for builtin macros outside
+of expected contexts can sometimes trigger warnings.  But most of the
+time, such tokens are silently converted to the empty string.
+
+@example
+$ @kbd{m4 -d}

+define(defn(`divnum'), `cannot redefine a builtin token')
+@error{}m4:stdin:2: Warning: define: invalid macro name ignored

+lift this restriction.

+$ @kbd{m4 -d}

+@cindex stack, macro definition
+It is possible to redefine a macro temporarily, reverting to the

+@code{pushdef} and @code{popdef}:
+
+@deffn Builtin pushdef (@var{name}, @ovar{expansion})
+@deffnx Builtin popdef (@var{name}@dots{})
+Analogous to @code{define} and @code{undefine}.
+
+These macros work in a stack-like fashion.  A macro is temporarily
+redefined with @code{pushdef}, which replaces an existing definition of
+@var{name}, while saving the previous definition, before the new one is
+installed.  If there is no previous definition, @code{pushdef} behaves
+exactly like @code{define}.
+
+If a macro has several definitions (of which only one is accessible),
+the topmost definition can be removed with @code{popdef}.  If there is
+no previous definition, @code{popdef} behaves like @code{undefine}.
+
+The expansion of both @code{pushdef} and @code{popdef} is void.
+The macros @code{pushdef} and @code{popdef} are recognized only with
+parameters.

+
+If a macro with several definitions is redefined with @code{define}, the
+topmost definition is @emph{replaced} with the new definition.  If it is
+removed with @code{undefine}, @emph{all} the definitions are removed,
+and not only the topmost one.  However, POSIX allows other
+implementations that treat @code{define} as replacing an entire stack
+of definitions with a single new definition, so to be portable to other
+implementations, it may be worth explicitly using @code{popdef} and
+@code{pushdef} rather than relying on the GNU behavior of
+@code{define}.
+
+@example
+define(`foo', `Expansion one.')
+@result{}
+foo
+@result{}Expansion one.
+pushdef(`foo', `Expansion two.')

+The point is, here, that larger macro packages can have private macros

+
+One other point to observe is that argument collection occurs before

+value of @var{name}, that will be reflected in the final expansion.
+This is different than the behavior when invoking macros directly,
+where the definition that was in effect before argument collection is

+The other conditional, @code{ifelse}, is much more powerful.  It can be
+used as a way to introduce a long comment, as an if-else construct, or
+as a multibranch, depending on the number of arguments supplied:
+
+@deffn Builtin ifelse (@var{comment})
+@deffnx Builtin ifelse (@var{string-1}, @var{string-2}, @var{equal}, @

+Used with only one argument, the @code{ifelse} simply discards it and
+produces no output.
+
+If called with three or four arguments, @code{ifelse} expands into
+@var{equal}, if @var{string-1} and @var{string-2} are equal (character
+for character), otherwise it expands to @var{not-equal}.  A final fifth
+argument is ignored, after triggering a warning.
+
+If called with six or more arguments, and @var{string-1} and
+@var{string-2} are equal, @code{ifelse} expands into @var{equal-1},
+otherwise the first three arguments are discarded and the processing
+starts again.
+
+The macro @code{ifelse} is recognized only with parameters.
+@end deffn
+
+Using only one argument is a common @code{m4} idiom for introducing a
+block comment, as an alternative to repeatedly using @code{dnl}.  This
+special usage is recognized by GNU @code{m4}, so that in this
+case, the warning about missing arguments is never triggered.

+@example
+ifelse(`some comments')
+@result{}
+ifelse(`foo', `bar')
+@error{}m4:stdin:2: Warning: too few arguments to builtin `ifelse'

+define(`foo', `bar')

+@end example
+
+@cindex macro, blind
+@cindex blind macro
+Notice how the first argument was used unquoted; it is common to compare
+the expansion of a macro with a string.  With this macro, you can now
+reproduce the behavior of blind builtins, where the macro is recognized
+only with arguments.
+
+@example
+define(`foo', `ifelse(`$#', `0', ``$0'', `arguments:$#')')
+@result{}
+foo
+@result{}foo
+foo()

+
+For an example of a way to make defining blind macros easier, see
+@ref{Composition}.
+
+@cindex multibranches
+@cindex switch statement
+@cindex case statement
+The macro @code{ifelse} can take more than four arguments.  If given more
+than four arguments, @code{ifelse} works like a @code{case} or @code{switch}
+statement in traditional programming languages.  If @var{string-1} and
+@var{string-2} are equal, @code{ifelse} expands into @var{equal-1}, otherwise
+the procedure is repeated with the first three arguments discarded.  This
+calls for an example:

+@example

+@end ignore
+
+Naturally, the normal case will be slightly more advanced than these
+examples.  A common use of @code{ifelse} is in macros implementing loops
+of various kinds.
+
+@node Shift
+@section Recursion in @code{m4}
+
+@cindex recursive macros
+@cindex macros, recursive
+There is no direct support for loops in @code{m4}, but macros can be
+recursive.  There is no limit on the number of recursion levels, other
+than those enforced by your hardware and operating system.
+
+@cindex loops
+Loops can be programmed using recursion and the conditionals described
+previously.
+
+There is a builtin macro, @code{shift}, which can, among other things,
+be used for iterating through the actual arguments to a macro:
+
+@deffn Builtin shift (@var{arg1}, @dots{})
+Takes any number of arguments, and expands to all its arguments except
+@var{arg1}, separated by commas, with each argument quoted.
+
+The macro @code{shift} is recognized only with parameters.
+@end deffn
+
+@example
+shift
+@result{}shift
+shift(`bar')
+@result{}
+shift(`foo', `bar', `baz')
+@result{}bar,baz
+@end example
+
+An example of the use of @code{shift} is this macro:
+
+@cindex reversing arguments
+@cindex arguments, reversing
+@deffn Composite reverse (@dots{})
+Takes any number of arguments, and reverses their order.
+@end deffn
+
+It is implemented as:
+
+@example
+define(`reverse', `ifelse(`$#', `0', , `$#', `1', ``$1'',
+                          `reverse(shift($@@)), `$1'')')
+@result{}
+reverse
+@result{}
+reverse(`foo')
+@result{}foo
+reverse(`foo', `bar', `gnats', `and gnus')
+@result{}and gnus, gnats, bar, foo
+@end example
+
+While not a very interesting macro, it does show how simple loops can be
+made with @code{shift}, @code{ifelse} and recursion.  It also shows
+that @code{shift} is usually used with @samp{$@@}.  Another example of
+this is an implementation of a short-circuiting conditional operator.
+
+@cindex short-circuiting conditional
+@cindex conditional, short-circuiting
+@deffn Composite cond (@var{test-1}, @var{string-1}, @var{equal-1}, @
+  @ovar{test-2}, @ovar{string-2}, @ovar{equal-2}, @dots{}, @ovar{not-equal})
+Similar to @code{ifelse}, where an equal comparison between the first
+two strings results in the third, otherwise the first three arguments
+are discarded and the process repeats.  The difference is that each
+@var{test-<n>} is expanded only when it is encountered.  This means that
+every third argument to @code{cond} is normally given one more level of
+quoting than the corresponding argument to @code{ifelse}.
+@end deffn
+
+Here is the implementation of @code{cond}, along with a demonstration of
+how it can short-circuit the side effects in @code{side}.  Notice how
+all the unquoted side effects happen regardless of how many comparisons
+are made with @code{ifelse}, compared with only the relevant effects
+with @code{cond}.
+
+@example
+define(`cond',
+`ifelse(`$#', `1', `$1',
+        `ifelse($1, `$2', `$3',
+                `$0(shift(shift(shift($@@))))')')')dnl
+define(`side', `define(`counter', incr(counter))$1')dnl
+define(`example1',
+`define(`counter', `0')dnl
+ifelse(side(`$1'), `yes', `one comparison: ',
+       side(`$1'), `no', `two comparisons: ',
+       side(`$1'), `maybe', `three comparisons: ',
+       `side(`default answer: ')')counter')dnl
+define(`example2',
+`define(`counter', `0')dnl
+cond(`side(`$1')', `yes', `one comparison: ',
+     `side(`$1')', `no', `two comparisons: ',
+     `side(`$1')', `maybe', `three comparisons: ',
+     `side(`default answer: ')')counter')dnl
+example1(`yes')
+@result{}one comparison: 3
+example1(`no')
+@result{}two comparisons: 3
+example1(`maybe')
+@result{}three comparisons: 3
+example1(`feeling rather indecisive today')
+@result{}default answer: 4
+example2(`yes')
+@result{}one comparison: 1
+example2(`no')
+@result{}two comparisons: 2
+example2(`maybe')
+@result{}three comparisons: 3
+example2(`feeling rather indecisive today')
+@result{}default answer: 4
+@end example
+
+@cindex joining arguments
+@cindex arguments, joining
+@cindex concatenating arguments
+Another common task that requires iteration is joining a list of
+arguments into a single string.
+
+@deffn Composite join (@ovar{separator}, @ovar{args@dots{}})
+@deffnx Composite joinall (@ovar{separator}, @ovar{args@dots{}})
+Generate a single-quoted string, consisting of each @var{arg} separated
+by @var{separator}.  While @code{joinall} always outputs a
+@var{separator} between arguments, @code{join} avoids the
+@var{separator} for an empty @var{arg}.
+@end deffn
+
+Here are some examples of its usage, based on the implementation
+@file{m4-@value{VERSION}/@/examples/@/join.m4} distributed in this
+package:
+
+@comment examples

+
+Examining the implementation shows some interesting points about several
+m4 programming idioms.
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+undivert(`join.m4')dnl
+@result{}divert(`-1')
+@result{}# join(sep, args) - join each non-empty ARG into a single
+@result{}# string, with each element separated by SEP
+@result{}define(`join',
+@result{}`ifelse(`$#', `2', ``$2'',
+@result{}  `ifelse(`$2', `', `', ``$2'_')$0(`$1', shift(shift($@@)))')')
+@result{}define(`_join',
+@result{}`ifelse(`$#$2', `2', `',
+@result{}  `ifelse(`$2', `', `', ``$1$2'')$0(`$1', shift(shift($@@)))')')
+@result{}# joinall(sep, args) - join each ARG, including empty ones,
+@result{}# into a single string, with each element separated by SEP
+@result{}define(`joinall', ``$2'_$0(`$1', shift($@@))')
+@result{}define(`_joinall',
+@result{}`ifelse(`$#', `2', `', ``$1$3'$0(`$1', shift(shift($@@)))')')
+@result{}divert`'dnl
+@end example
+
+First, notice that this implementation creates helper macros
+@code{_join} and @code{_joinall}.  This division of labor makes it
+easier to output the correct number of @var{separator} instances:
+@code{join} and @code{joinall} are responsible for the first argument,
+without a separator, while @code{_join} and @code{_joinall} are
+responsible for all remaining arguments, always outputting a separator
+when outputting an argument.
+
+Next, observe how @code{join} decides to iterate to itself, because the
+first @var{arg} was empty, or to output the argument and swap over to
+@code{_join}.  If the argument is non-empty, then the nested
+@code{ifelse} results in an unquoted @samp{_}, which is concatenated
+with the @samp{$0} to form the next macro name to invoke.  The
+@code{joinall} implementation is simpler since it does not have to
+suppress empty @var{arg}; it always executes once then defers to
+@code{_joinall}.
+
+Another important idiom is the idea that @var{separator} is reused for
+each iteration.  Each iteration has one less argument, but rather than
+discarding @samp{$1} by iterating with @code{$0(shift($@@))}, the macro
+discards @samp{$2} by using @code{$0(`$1', shift(shift($@@)))}.
+
+Next, notice that it is possible to compare more than one condition in a
+single @code{ifelse} test.  The test of @samp{$#$2} against @samp{2}
+allows @code{_join} to iterate for two separate reasons---either there
+are still more than two arguments, or there are exactly two arguments
+but the last argument is not empty.
+
+Finally, notice that these macros require exactly two arguments to
+terminate recursion, but that they still correctly result in empty
+output when given no @var{args} (i.e., zero or one macro argument).  On
+the first pass when there are too few arguments, the @code{shift}
+results in no output, but leaves an empty string to serve as the
+required second argument for the second pass.  Put another way,
+@samp{`$1', shift($@@)} is not the same as @samp{$@@}, since only the
+former guarantees at least two arguments.
+
+@cindex quote manipulation
+@cindex manipulating quotes
+Sometimes, a recursive algorithm requires adding quotes to each element,
+or treating multiple arguments as a single element:
+
+@deffn Composite quote (@dots{})
+@deffnx Composite dquote (@dots{})
+@deffnx Composite dquote_elt (@dots{})
+Takes any number of arguments, and adds quoting.  With @code{quote},
+only one level of quoting is added, effectively removing whitespace
+after commas and turning multiple arguments into a single string.  With
+@code{dquote}, two levels of quoting are added, one around each element,
+and one around the list.  And with @code{dquote_elt}, two levels of
+quoting are added around each element.
+@end deffn
+
+An actual implementation of these three macros is distributed as
+@file{m4-@value{VERSION}/@/examples/@/quote.m4} in this package.  First,
+let's examine their usage:
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+include(`quote.m4')
+@result{}
+-quote-dquote-dquote_elt-
+@result{}----
+-quote()-dquote()-dquote_elt()-
+@result{}--`'-`'-
+-quote(`1')-dquote(`1')-dquote_elt(`1')-
+@result{}-1-`1'-`1'-
+-quote(`1', `2')-dquote(`1', `2')-dquote_elt(`1', `2')-
+@result{}-1,2-`1',`2'-`1',`2'-
+define(`n', `$#')dnl
+-n(quote(`1', `2'))-n(dquote(`1', `2'))-n(dquote_elt(`1', `2'))-
+@result{}-1-1-2-
+dquote(dquote_elt(`1', `2'))
+@result{}``1'',``2''
+dquote_elt(dquote(`1', `2'))
+@result{}``1',`2''
+@end example
+
+The last two lines show that when given two arguments, @code{dquote}
+results in one string, while @code{dquote_elt} results in two.  Now,
+examine the implementation.  Note that @code{quote} and
+@code{dquote_elt} make decisions based on their number of arguments, so
+that when called without arguments, they result in nothing instead of a
+quoted empty string; this is so that it is possible to distinguish
+between no arguments and an empty first argument.  @code{dquote}, on the
+other hand, results in a string no matter what, since it is still
+possible to tell whether it was invoked without arguments based on the
+resulting string.
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+undivert(`quote.m4')dnl
+@result{}divert(`-1')
+@result{}# quote(args) - convert args to single-quoted string
+@result{}define(`quote', `ifelse(`$#', `0', `', ``$*'')')
+@result{}# dquote(args) - convert args to quoted list of quoted strings
+@result{}define(`dquote', ``$@@'')
+@result{}# dquote_elt(args) - convert args to list of double-quoted strings
+@result{}define(`dquote_elt', `ifelse(`$#', `0', `', `$#', `1', ```$1''',
+@result{}                             ```$1'',$0(shift($@@))')')
+@result{}divert`'dnl
+@end example
+
+It is worth pointing out that @samp{quote(@var{args})} is more efficient
+than @samp{joinall(`,', @var{args})} for producing the same output.
+
+@cindex nine arguments, more than
+@cindex more than nine arguments
+@cindex arguments, more than nine
+One more useful macro based on @code{shift} allows portably selecting
+an arbitrary argument (usually greater than the ninth argument), without
+relying on the GNU extension of multi-digit arguments
+(@pxref{Arguments}).
+
+@deffn Composite argn (@var{n}, @dots{})
+Expands to argument @var{n} out of the remaining arguments.  @var{n}
+must be a positive number.  Usually invoked as
+@samp{argn(`@var{n}',$@@)}.
+@end deffn
+
+It is implemented as:
+
+@example
+define(`argn', `ifelse(`$1', 1, ``$2'',
+  `argn(decr(`$1'), shift(shift($@@)))')')
+@result{}
+argn(`1', `a')

+@cindex for loops
+@cindex loops, counting
+@cindex counting loops
+Here is an example of a loop macro that implements a simple for loop.
+
+@deffn Composite forloop (@var{iterator}, @var{start}, @var{end}, @var{text})
+Takes the name in @var{iterator}, which must be a valid macro name, and
+successively assign it each integer value from @var{start} to @var{end},
+inclusive.  For each assignment to @var{iterator}, append @var{text} to
+the expansion of the @code{forloop}.  @var{text} may refer to
+@var{iterator}.  Any definition of @var{iterator} prior to this
+invocation is restored.
+@end deffn
+
+It can, for example, be used for simple counting:

+
+For-loops can be nested, like:

+@result{}
+@end example
+
+The implementation of the @code{forloop} macro is fairly
+straightforward.  The @code{forloop} macro itself is simply a wrapper,
+which saves the previous definition of the first argument, calls the
+internal macro @code{@w{_forloop}}, and re-establishes the saved
+definition of the first argument.
+
+The macro @code{@w{_forloop}} expands the fourth argument once, and
+tests to see if the iterator has reached the final value.  If it has
+not finished, it increments the iterator (using the predefined macro
+@code{incr}, @pxref{Incr}), and recurses.
+
+Here is an actual implementation of @code{forloop}, distributed as
+@file{m4-@value{VERSION}/@/examples/@/forloop.m4} in this package:
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}

+@result{}       `$4`'ifelse($1, `$3', `', `define(`$1', incr($1))$0($@@)')')
+@result{}divert`'dnl
+@end example
+
+Notice the careful use of quotes.  Certain macro arguments are left
+unquoted, each for its own reason.  Try to find out @emph{why} these
+arguments are left unquoted, and see what happens if they are quoted.
+(As presented, these two macros are useful but not very robust for
+general use.  They lack even basic error handling for cases like
+@var{start} less than @var{end}, @var{end} not numeric, or
+@var{iterator} not being a macro name.  See if you can improve these
+macros; or @pxref{Improved forloop, , Answers}).

+@node Foreach
+@section Iteration by list contents
+
+@cindex for each loops
+@cindex loops, list iteration
+@cindex iterating over lists
+Here is an example of a loop macro that implements list iteration.
+
+@deffn Composite foreach (@var{iterator}, @var{paren-list}, @var{text})
+@deffnx Composite foreachq (@var{iterator}, @var{quote-list}, @var{text})
+Takes the name in @var{iterator}, which must be a valid macro name, and
+successively assign it each value from @var{paren-list} or
+@var{quote-list}.  In @code{foreach}, @var{paren-list} is a
+comma-separated list of elements contained in parentheses.  In
+@code{foreachq}, @var{quote-list} is a comma-separated list of elements
+contained in a quoted string.  For each assignment to @var{iterator},
+append @var{text} to the overall expansion.  @var{text} may refer to
+@var{iterator}.  Any definition of @var{iterator} prior to this
+invocation is restored.
+@end deffn
+
+As an example, this displays each word in a list inside of a sentence,
+using an implementation of @code{foreach} distributed as

+in @file{m4-@value{VERSION}/@/examples/@/foreachq.m4}.

+@end example
+
+It is possible to be more complex; each element of the @var{paren-list}
+or @var{quote-list} can itself be a list, to pass as further arguments
+to a helper macro.  This example generates a shell case statement:
+
+@comment examples
+@example

+include(`foreach.m4')
+@result{}
+define(`_case', `  $1)

+@result{}  b)

+@result{}  c)
+@result{}    varc=" c";;
+esac
+@result{}esac
+@end example
+
+The implementation of the @code{foreach} macro is a bit more involved;
+it is a wrapper around two helper macros.  First, @code{@w{_arg1}} is
+needed to grab the first element of a list.  Second,
+@code{@w{_foreach}} implements the recursion, successively walking
+through the original list.  Here is a simple implementation of
+@code{foreach}:
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+undivert(`foreach.m4')dnl
+@result{}divert(`-1')
+@result{}# foreach(x, (item_1, item_2, ..., item_n), stmt)
+@result{}#   parenthesized list, simple version
+@result{}define(`foreach', `pushdef(`$1')_foreach($@@)popdef(`$1')')
+@result{}define(`_arg1', `$1')
+@result{}define(`_foreach', `ifelse(`$2', `()', `',
+@result{}  `define(`$1', _arg1$2)$3`'$0(`$1', (shift$2), `$3')')')
+@result{}divert`'dnl
+@end example
+
+Unfortunately, that implementation is not robust to macro names as list
+elements.  Each iteration of @code{@w{_foreach}} is stripping another
+layer of quotes, leading to erratic results if list elements are not
+already fully expanded.  The first cut at implementing @code{foreachq}
+takes this into account.  Also, when using quoted elements in a
+@var{paren-list}, the overall list must be quoted.  A @var{quote-list}
+has the nice property of requiring fewer characters to create a list
+containing the same quoted elements.  To see the difference between the
+two macros, we attempt to pass double-quoted macro names in a list,
+expecting the macro name on output after one layer of quotes is removed
+during list iteration and the final layer removed during the final
+rescan:

+contains a comma.  Unfortunately, this implementation of @code{foreachq}
+has its own severe flaw.  Whereas the @code{foreach} implementation was
+linear, this macro is quadratic in the number of list elements, and is
+much more likely to trip up the limit set by the command line option
+@option{--nesting-limit} (or @option{-L}, @pxref{Limits control, ,
+Invoking m4}).  Additionally, this implementation does not expand
+@samp{defn(`@var{iterator}')} very well, when compared with
+@code{foreach}.

+@node Stacks

+
+@cindex definition stack
+@cindex pushdef stack
+@cindex stack, macro definition
+Thanks to @code{pushdef}, manipulation of a stack is an intrinsic
+operation in @code{m4}.  Normally, only the topmost definition in a
+stack is important, but sometimes, it is desirable to manipulate the
+entire definition stack.
+
+@deffn Composite stack_foreach (@var{macro}, @var{action})
+@deffnx Composite stack_foreach_lifo (@var{macro}, @var{action})
+For each of the @code{pushdef} definitions associated with @var{macro},
+invoke the macro @var{action} with a single argument of that definition.
+@code{stack_foreach} visits the oldest definition first, while
+@code{stack_foreach_lifo} visits the current definition first.
+@var{action} should not modify or dereference @var{macro}.  There are a
+few special macros, such as @code{defn}, which cannot be used as the
+@var{macro} parameter.
+@end deffn
+
+A sample implementation of these macros is distributed in the file
+@file{m4-@value{VERSION}/@/examples/@/stack.m4}.
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+include(`stack.m4')

+stack_foreach_lifo(`a', `show')dnl
+@result{}3
+@result{}2
+@result{}1
+@end example
+
+Now for the implementation.  Note the definition of a helper macro,
+@code{_stack_reverse}, which destructively swaps the contents of one
+stack of definitions into the reverse order in the temporary macro
+@samp{tmp-$1}.  By calling the helper twice, the original order is
+restored back into the macro @samp{$1}; since the operation is
+destructive, this explains why @samp{$1} must not be modified or
+dereferenced during the traversal.  The caller can then inject
+additional code to pass the definition currently being visited to
+@samp{$2}.  The choice of helper names is intentional; since @samp{-} is
+not valid as part of a macro name, there is no risk of conflict with a
+valid macro name, and the code is guaranteed to use @code{defn} where
+necessary.  Finally, note that any macro used in the traversal of a
+@code{pushdef} stack, such as @code{pushdef} or @code{defn}, cannot be
+handled by @code{stack_foreach}, since the macro would temporarily be
+undefined during the algorithm.

+@node Composition
+@section Building macros with macros
+
+@cindex macro composition
+@cindex composing macros
+Since m4 is a macro language, it is possible to write macros that
+can build other macros.  First on the list is a way to automate the
+creation of blind macros.
+
+@cindex macro, blind
+@cindex blind macro
+@deffn Composite define_blind (@var{name}, @ovar{value})
+Defines @var{name} as a blind macro, such that @var{name} will expand to
+@var{value} only when given explicit arguments.  @var{value} should not
+be the result of @code{defn} (@pxref{Defn}).  This macro is only
+recognized with parameters, and results in an empty string.
+@end deffn
+
+Defining a macro to define another macro can be a bit tricky.  We want
+to use a literal @samp{$#} in the argument to the nested @code{define}.
+However, if @samp{$} and @samp{#} are adjacent in the definition of
+@code{define_blind}, then it would be expanded as the number of
+arguments to @code{define_blind} rather than the intended number of
+arguments to @var{name}.  The solution is to pass the difficult
+characters through extra arguments to a helper macro
+@code{_define_blind}.  When composing macros, it is a common idiom to
+need a helper macro to concatenate text that forms parameters in the
+composed macro, rather than interpreting the text as a parameter of the
+composing macro.
+
+As for the limitation against using @code{defn}, there are two reasons.
+If a macro was previously defined with @code{define_blind}, then it can
+safely be renamed to a new blind macro using plain @code{define}; using
+@code{define_blind} to rename it just adds another layer of
+@code{ifelse}, occupying memory and slowing down execution.  And if a
+macro is a builtin, then it would result in an attempt to define a macro
+consisting of both text and a builtin token; this is not supported, and
+the builtin token is flattened to an empty string.
+
+With that explanation, here's the definition, and some sample usage.
+Notice that @code{define_blind} is itself a blind macro.
+
+@example
+$ @kbd{m4 -d}
+define(`define_blind', `ifelse(`$#', `0', ``$0'',
+`_$0(`$1', `$2', `$'`#', `$'`0')')')
+@result{}
+define(`_define_blind', `define(`$1',
+`ifelse(`$3', `0', ``$4'', `$2')')')
+@result{}
+define_blind
+@result{}define_blind
+define_blind(`foo', `arguments were $*')
+@result{}
+foo
+@result{}foo
+foo(`bar')
+@result{}arguments were bar
+define(`blah', defn(`foo'))
+@result{}
+blah
+@result{}blah
+blah(`a', `b')
+@result{}arguments were a,b
+defn(`blah')
+@result{}ifelse(`$#', `0', ``$0'', `arguments were $*')
+@end example
+
+@cindex currying arguments
+@cindex argument currying
+Another interesting composition tactic is argument @dfn{currying}, or
+factoring a macro that takes multiple arguments for use in a context
+that provides exactly one argument.
+
+@deffn Composite curry (@var{macro}, @dots{})
+Expand to a macro call that takes exactly one argument, then appends
+that argument to the original arguments and invokes @var{macro} with the
+resulting list of arguments.
+@end deffn
+
+A demonstration of currying makes the intent of this macro a little more
+obvious.  The macro @code{stack_foreach} mentioned earlier is an example
+of a context that provides exactly one argument to a macro name.  But
+coupled with currying, we can invoke @code{reverse} with two arguments
+for each definition of a macro stack.  This example uses the file
+@file{m4-@value{VERSION}/@/examples/@/curry.m4} included in the
+distribution.
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+include(`curry.m4')include(`stack.m4')
+@result{}
+define(`reverse', `ifelse(`$#', `0', , `$#', `1', ``$1'',
+                          `reverse(shift($@@)), `$1'')')
+@result{}
+pushdef(`a', `1')pushdef(`a', `2')pushdef(`a', `3')
+@result{}
+stack_foreach(`a', `:curry(`reverse', `4')')
+@result{}:1, 4:2, 4:3, 4
+curry(`curry', `reverse', `1')(`2')(`3')
+@result{}3, 2, 1
+@end example
+
+Now for the implementation.  Notice how @code{curry} leaves off with a
+macro name but no open parenthesis, while still in the middle of
+collecting arguments for @samp{$1}.  The macro @code{_curry} is the
+helper macro that takes one argument, then adds it to the list and
+finally supplies the closing parenthesis.  The use of a comma inside the
+@code{shift} call allows currying to also work for a macro that takes
+one argument, although it often makes more sense to invoke that macro
+directly rather than going through @code{curry}.
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+undivert(`curry.m4')dnl
+@result{}divert(`-1')
+@result{}# curry(macro, args)
+@result{}# Expand to a macro call that takes one argument, then invoke
+@result{}# macro(args, extra).
+@result{}define(`curry', `$1(shift($@@,)_$0')
+@result{}define(`_curry', ``$1')')
+@result{}divert`'dnl
+@end example
+
+Unfortunately, with M4 1.4.x, @code{curry} is unable to handle builtin
+tokens, which are silently flattened to the empty string when passed
+through another text macro.  This limitation will be lifted in a future
+release of M4.
+
+@cindex renaming macros
+@cindex copying macros
+@cindex macros, copying
+Putting the last few concepts together, it is possible to copy or rename
+an entire stack of macro definitions.
+
+@deffn Composite copy (@var{source}, @var{dest})
+@deffnx Composite rename (@var{source}, @var{dest})
+Ensure that @var{dest} is undefined, then define it to the same stack of
+definitions currently in @var{source}.  @code{copy} leaves @var{source}
+unchanged, while @code{rename} undefines @var{source}.  There are only a
+few macros, such as @code{copy} or @code{defn}, which cannot be copied
+via this macro.
+@end deffn
+
+The implementation is relatively straightforward (although since it uses
+@code{curry}, it is unable to copy builtin macros, such as the second
+definition of @code{a} as a synonym for @code{divnum}.  See if you can
+design a version that works around this limitation, or @pxref{Improved
+copy, , Answers}).

+@cindex input, discarding
+The builtin @code{dnl} stands for ``Discard to Next Line'':
+
+@deffn Builtin dnl
+All characters, up to and including the next newline, are discarded
+without performing any macro expansion.  A warning is issued if the end
+of the file is encountered without a newline.
+
+The expansion of @code{dnl} is void.
+@end deffn
+
+It is often used in connection with @code{define}, to remove the
+newline that follows the call to @code{define}.  Thus
+
+@example
+define(`foo', `Macro `foo'.')dnl A very simple macro, indeed.
+foo
+@result{}Macro foo.
+@end example
+
+The input up to and including the next newline is discarded, as opposed
+to the way comments are treated (@pxref{Comments}).
+
+Usually, @code{dnl} is immediately followed by an end of line or some
+other whitespace.  GNU @code{m4} will produce a warning diagnostic if
+@code{dnl} is followed by an open parenthesis.  In this case, @code{dnl}
+will collect and process all arguments, looking for a matching close
+parenthesis.  All predictable side effects resulting from this
+collection will take place.  @code{dnl} will return no output.  The
+input following the matching close parenthesis up to and including the
+next newline, on whatever line containing it, will still be discarded.
+
+@example
+dnl(`args are ignored, but side effects occur',
+define(`foo', `like this')) while this text is ignored: undefine(`foo')
+@error{}m4:stdin:1: Warning: excess arguments to builtin `dnl' ignored

+
+If the end of file is encountered without a newline character, a

+@cindex delimiters, changing
+The default quote delimiters can be changed with the builtin
+@code{changequote}:
+
+@deffn Builtin changequote (@dvar{start, `}, @dvar{end, '})
+This sets @var{start} as the new begin-quote delimiter and @var{end} as
+the new end-quote delimiter.  If both arguments are missing, the default
+quotes (@code{`} and @code{'}) are used.  If @var{start} is void, then
+quoting is disabled.  Otherwise, if @var{end} is missing or void, the
+default end-quote delimiter (@code{'}) is used.  The quote delimiters
+can be of any length.
+
+The expansion of @code{changequote} is void.
+@end deffn
+
+@example
+changequote(`', `')
+@result{}
+define(foo, Macro foo.)
+@result{}
+foo
+@result{}Macro foo.
+@end example
+
+The quotation strings can safely contain non-@sc{ascii} characters.
+
+@example
+define(`a', `b')
+@result{}
+«a»
+@result{}«b»
+changequote(`«', `»')
+@result{}
+«a»
+@result{}a
+@end example
+
+If no single character is appropriate, @var{start} and @var{end} can be
+of any length.  Other implementations cap the delimiter length to five
+characters, but GNU has no inherent limit.
+
+@example
+changequote(`', `')
+@result{}
+define(foo, Macro foo.)
+@result{}
+foo
+@result{}Macro foo.
+@end example
+
+Calling @code{changequote} with @var{start} as the empty string will
+effectively disable the quoting mechanism, leaving no way to quote text.
+However, using an empty string is not portable, as some other
+implementations of @code{m4} revert to the default quoting, while others
+preserve the prior non-empty delimiter.  If @var{start} is not empty,
+then an empty @var{end} will use the default end-quote delimiter of
+@samp{'}, as otherwise, it would be impossible to end a quoted string.
+Again, this is not portable, as some other @code{m4} implementations
+reuse @var{start} as the end-quote delimiter, while others preserve the
+previous non-empty value.  Omitting both arguments restores the default
+begin-quote and end-quote delimiters; fortunately this behavior is
+portable to all implementations of @code{m4}.
+
+@example
+define(`foo', `Macro `FOO'.')
+@result{}
+changequote(`', `')
+@result{}
+foo
+@result{}Macro `FOO'.
+`foo'
+@result{}`Macro `FOO'.'
+changequote(`,)
+@result{}
+foo
+@result{}Macro FOO.
+@end example
+
+There is no way in @code{m4} to quote a string containing an unmatched
+begin-quote, except using @code{changequote} to change the current
+quotes.
+
+If the quotes should be changed from, say, @samp{} to @samp{},
+temporary quote characters have to be defined.  To achieve this, two
+calls of @code{changequote} must be made, one for the temporary quotes
+and one for the new quotes.
+
+Macros are recognized in preference to the begin-quote string, so if a
+prefix of @var{start} can be recognized as part of a potential macro
+name, the quoting mechanism is effectively disabled.  Unless you use
+@code{changeword} (@pxref{Changeword}), this means that @var{start}
+should not begin with a letter, digit, or @samp{_} (underscore).
+However, even though quoted strings are not recognized, the quote
+characters can still be discerned in macro expansion and in trace
+output.
+
+@example
+define(`echo', `$@@')
+@result{}
+define(`hi', `HI')
+@result{}
+changequote(`q', `Q')
+@result{}
+q hi Q hi
+@result{}q HI Q HI
+echo(hi)
+@result{}qHIQ
+changequote
+@result{}
+changequote(`-', `EOF')
+@result{}
+- hi EOF hi
+@result{} hi  HI
+changequote
+@result{}
+changequote(`1', `2')
+@result{}
+hi1hi2
+@result{}hi1hi2
+hi 1hi2
+@result{}HI hi
+@end example
+
+Quotes are recognized in preference to argument collection.  In
+particular, if @var{start} is a single @samp{(}, then argument
+collection is effectively disabled.  For portability with other
+implementations, it is a good idea to avoid @samp{(}, @samp{,}, and
+@samp{)} as the first character in @var{start}.
+
+@example
+define(`echo', `$#:$@@:')
+@result{}
+define(`hi', `HI')
+@result{}
+changequote(`(',`)')
+@result{}
+echo(hi)
+@result{}0::hi
+changequote
+@result{}
+changequote(`((', `))')
+@result{}
+echo(hi)
+@result{}1:HI:
+echo((hi))
+@result{}0::hi
+changequote
+@result{}
+changequote(`,', `)')
+@result{}
+echo(hi,hi)bye)
+@result{}1:HIhibye:
+@end example
+
+However, if you are not worried about portability, using @samp{(} and
+@samp{)} as quoting characters has an interesting property---you can use
+it to compute a quoted string containing the expansion of any quoted
+text, as long as the expansion results in both balanced quotes and
+balanced parentheses.  The trick is realizing @code{expand} uses
+@samp{$1} unquoted, to trigger its expansion using the normal quoting
+characters, but uses extra parentheses to group unquoted commas that
+occur in the expansion without consuming whitespace following those
+commas.  Then @code{_expand} uses @code{changequote} to convert the
+extra parentheses back into quoting characters.  Note that it takes two
+more @code{changequote} invocations to restore the original quotes.
+Contrast the behavior on whitespace when using @samp{$*}, via
+@code{quote}, to attempt the same task.
+
+@example
+changequote(`', `')dnl
+define(a, 1, (b))dnl
+define(b, 2)dnl
+define(quote, $*)dnl
+define(expand, _$0(($1)))dnl
+define(_expand,
+  changequote((, ))$1changequote`'changequote(`', `'))dnl
+expand(a, a, a, a, a, a)
+@result{}1, (2), 1, (2), a, a, a, a
+quote(a, a, a, a, a, a)
+@result{}1,(2),1,(2),a, a,a, a
+@end example
+
+If @var{end} is a prefix of @var{start}, the end-quote will be
+recognized in preference to a nested begin-quote.  In particular,
+changing the quotes to have the same string for @var{start} and
+@var{end} disables nesting of quotes.  When quote nesting is disabled,
+it is impossible to double-quote strings across macro expansions, so
+using the same string is not done very often.
+
+@example
+define(`hi', `HI')
+@result{}
+changequote(`""', `"')
+@result{}
+""hi"""hi"
+@result{}hihi
+""hi" ""hi"
+@result{}hi hi
+""hi"" "hi"
+@result{}hi" "HI"
+changequote

+@result{}hi`hi'hi
+changequote(`"', `"')
+@result{}
+"hi"hi"hi"
+@result{}hiHIhi

+The macro @code{changeword} and all associated functionality is
+experimental.  It is only available if the @option{--enable-changeword}
+option was given to @command{configure}, at GNU @code{m4}
+installation
+time.  The functionality will go away in the future, to be replaced by
+other new features that are more efficient at providing the same
+capabilities.  @emph{Do not rely on it}.  Please direct your comments
+about it the same way you would do for bugs.
+@end quotation
+
+A file being processed by @code{m4} is split into quoted strings, words
+(potential macro names) and simple tokens (any other single character).
+Initially a word is defined by the following regular expression:
+
+@comment ignore
+@example
+_a-zA-Z_a-zA-Z0-9*
+@end example
+
+Using @code{changeword}, you can change this regular expression:
+
+@deffn {Optional builtin} changeword (@var{regex})
+Changes the regular expression for recognizing macro names to be
+@var{regex}.  If @var{regex} is empty, use
+@samp{_a-zA-Z_a-zA-Z0-9*}.  @var{regex} must obey the constraint
+that every prefix of the desired final pattern is also accepted by the
+regular expression.  If @var{regex} contains grouping parentheses, the
+macro invoked is the portion that matched the first group, rather than
+the entire matching string.
+
+The expansion of @code{changeword} is void.
+The macro @code{changeword} is recognized only with parameters.
+@end deffn
+
+Relaxing the lexical rules of @code{m4} might be useful (for example) if
+you wanted to apply translations to a file of numbers:
+
+@example
+ifdef(`changeword', `', `errprint(` skipping: no changeword support
+')m4exit(`77')')dnl
+changeword(`_a-zA-Z0-9+')
+@result{}
+define(`1', `0')1
+@result{}0
+@end example
+
+Tightening the lexical rules is less useful, because it will generally
+make some of the builtins unavailable.  You could use it to prevent
+accidental call of builtins, for example:
+
+@example
+ifdef(`changeword', `', `errprint(` skipping: no changeword support
+')m4exit(`77')')dnl
+define(`_indir', defn(`indir'))
+@result{}
+changeword(`__a-zA-Z0-9*')
+@result{}
+esyscmd(`foo')
+@result{}esyscmd(foo)
+_indir(`esyscmd', `echo hi')
+@result{}hi
+@result{}
+@end example
+
+Because @code{m4} constructs its words a character at a time, there
+is a restriction on the regular expressions that may be passed to
+@code{changeword}.  This is that if your regular expression accepts
+@samp{foo}, it must also accept @samp{f} and @samp{fo}.
+
+@example
+ifdef(`changeword', `', `errprint(` skipping: no changeword support
+')m4exit(`77')')dnl
+define(`foo
+', `bar
+')
+@result{}
+dnl This example wants to recognize changeword, dnl, and `foo\n'.
+dnl First, we check that our regexp will match.
+regexp(`changeword', `cda-z*\|foo
+')
+@result{}0
+regexp(`foo
+', `cda-z*\|foo
+')
+@result{}0
+regexp(`f', `cda-z*\|foo
+')
+@result{}-1
+foo
+@result{}foo
+changeword(`cda-z*\|foo
+')
+@result{}
+dnl Even though `foo\n' matches, we forgot to allow `f'.
+foo
+@result{}foo
+changeword(`cda-z*\|fo*
+?')
+@result{}
+dnl Now we can call `foo\n'.
+foo
+@result{}bar
+@end example
+
+@ignore
+@comment One more test of including newline in a macro name; but this
+@comment does not need to be displayed in the manual.  This ensures
+@comment that line numbering is correct when dnl cuts across include
+@comment file boundaries, and when __file__ or __line__ is the last
+@comment token in an include file.
+
+@example
+ifdef(`changeword', `', `errprint(` skipping: no changeword support
+')m4exit(`77')')dnl
+define(`bar
+', defn(`dnl'))dnl
+define(`baz', `dnl
+include(`foo') ignored
+dnl')dnl
+changeword(`$_a-zA-Z_a-zA-Z0-9*\|bar
+$')
+@result{}
+__file__:__line__
+@result{}stdin:10
+include(`foo') ignored
+__file__:__line__
+@result{}stdin:12
+baz ignored
+__file__:__line__
+@result{}stdin:14
+define(`bar
+', defn(`__file__'))
+@result{}
+include(`foo')
+@result{}examples/foo
+define(`bar
+', defn(`__line__'))
+@result{}
+include(`foo')
+@result{}1
+__file__:__line__
+@result{}stdin:21
+@end example
+@end ignore
+
+@code{changeword} has another function.  If the regular expression
+supplied contains any grouped subexpressions, then text outside
+the first of these is discarded before symbol lookup.  So:
+
+@example
+ifdef(`changeword', `', `errprint(` skipping: no changeword support
+')m4exit(`77')')dnl
+ifdef(`__unix__', ,
+      `errprint(` skipping: syscmd does not have unix semantics
+')m4exit(`77')')dnl
+changecom(`/*', `*/')dnl
+define(`foo', `bar')dnl
+changeword(`#$_a-zA-Z0-9*$')
+@result{}
+#esyscmd(`echo foo \#foo')
+@result{}foo bar
+@result{}
+@end example
+
+@code{m4} now requires a @samp{#} mark at the beginning of every
+macro invocation, so one can use @code{m4} to preprocess plain
+text without losing various words like @samp{divert}.
+
+In @code{m4}, macro substitution is based on text, while in @TeX{}, it
+is based on tokens.  @code{changeword} can throw this difference into
+relief.  For example, here is the same idea represented in @TeX{} and
+@code{m4}.  First, the @TeX{} version:
+
+@comment ignore
+@example
+\def\a@{\message@{Hello@}@}
+\catcode`\@@=0
+\catcode`\\=12
+@@a
+@@bye
+@result{}Hello
+@end example
+
+@noindent
+Then, the @code{m4} version:
+
+@example
+ifdef(`changeword', `', `errprint(` skipping: no changeword support
+')m4exit(`77')')dnl
+define(`a', `errprint(`Hello')')dnl
+changeword(`@@$_a-zA-Z0-9*$')
+@result{}
+@@a
+@result{}errprint(Hello)
+@end example
+
+In the @TeX{} example, the first line defines a macro @code{a} to
+print the message @samp{Hello}.  The second line defines @key{@@} to
+be usable instead of @key{\} as an escape character.  The third line
+defines @key{\} to be a normal printing character, not an escape.
+The fourth line invokes the macro @code{a}.  So, when @TeX{} is run
+on this file, it displays the message @samp{Hello}.
+
+When the @code{m4} example is passed through @code{m4}, it outputs
+@samp{errprint(Hello)}.  The reason for this is that @TeX{} does
+lexical analysis of macro definition when the macro is @emph{defined}.
+@code{m4} just stores the text, postponing the lexical analysis until
+the macro is @emph{used}.
+
+You should note that using @code{changeword} will slow @code{m4} down
+by a factor of about seven, once it is changed to something other
+than the default regular expression.  You can invoke @code{changeword}
+with the empty string to restore the default word definition, and regain
+the parsing speed.

+It is possible to `save' some text until the end of the normal input has
+been seen.  Text can be saved, to be read again by @code{m4} when the
+normal input has been exhausted.  This feature is normally used to
+initiate cleanup actions before normal exit, e.g., deleting temporary
+files.
+
+To save input text, use the builtin @code{m4wrap}:
+
+@deffn Builtin m4wrap (@var{string}, @dots{})
+Stores @var{string} in a safe place, to be reread when end of input is
+reached.  As a GNU extension, additional arguments are
+concatenated with a space to the @var{string}.
+
+The expansion of @code{m4wrap} is void.
+The macro @code{m4wrap} is recognized only with parameters.
+@end deffn
+
+@example
+define(`cleanup', `This is the `cleanup' action.
+')
+@result{}
+m4wrap(`cleanup')
+@result{}
+This is the first and last normal input line.
+@result{}This is the first and last normal input line.
+^D
+@result{}This is the cleanup action.
+@end example
+
+The saved input is only reread when the end of normal input is seen, and
+not if @code{m4exit} is used to exit @code{m4}.
+
+@comment FIXME: this contradicts POSIX, which requires that "If the
+@comment m4wrap macro is used multiple times, the arguments specified
+@comment shall be processed in the order in which the m4wrap macros were
+@comment processed."
+It is safe to call @code{m4wrap} from saved text, but then the order in
+which the saved text is reread is undefined.  If @code{m4wrap} is not used
+recursively, the saved pieces of text are reread in the opposite order
+in which they were saved (LIFO---last in, first out).  However, this
+behavior is likely to change in a future release, to match
+POSIX, so you should not depend on this order.
+
+It is possible to emulate POSIX behavior even
+with older versions of GNU M4 by including the file
+@file{m4-@value{VERSION}/@/examples/@/wrapfifo.m4} from the
+distribution:

+@section Including named files
+
+There are two builtin macros in @code{m4} for including files:
+
+@deffn Builtin include (@var{file})
+@deffnx Builtin sinclude (@var{file})
+Both macros cause the file named @var{file} to be read by
+@code{m4}.  When the end of the file is reached, input is resumed from
+the previous input file.
+
+The expansion of @code{include} and @code{sinclude} is therefore the
+contents of @var{file}.
+
+If @var{file} does not exist, is a directory, or cannot otherwise be
+read, the expansion is void,
+and @code{include} will fail with an error while @code{sinclude} is
+silent.  The empty string counts as a file that does not exist.
+
+The macros @code{include} and @code{sinclude} are recognized only with
+parameters.

+The rest of this section assumes that @code{m4} is invoked with the
+@option{-I} option (@pxref{Preprocessor features, , Invoking m4})
+pointing to the @file{m4-@value{VERSION}/@/examples}
+directory shipped as part of the GNU @code{m4} package.  The
+file @file{m4-@value{VERSION}/@/examples/@/incl.m4} in the distribution
+contains the lines:
+
+@comment ignore
+@example
+$ @kbd{cat examples/incl.m4}
+@result{}Include file start
+@result{}foo
+@result{}Include file end
+@end example
+
+Normally file inclusion is used to insert the contents of a file
+into the input stream.  The contents of the file will be read by
+@code{m4} and macro calls in the file will be expanded:
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+define(`foo', `FOO')
+@result{}
+include(`incl.m4')
+@result{}Include file start
+@result{}FOO
+@result{}Include file end
+@result{}
+@end example
+
+The fact that @code{include} and @code{sinclude} expand to the contents
+of the file can be used to define macros that operate on entire files.
+Here is an example, which defines @samp{bar} to expand to the contents
+of @file{incl.m4}:
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+define(`bar', include(`incl.m4'))
+@result{}
+This is `bar':  >>bar<<
+@result{}This is bar:  >>Include file start
+@result{}foo
+@result{}Include file end
+@result{}<<
+@end example
+
+This use of @code{include} is not trivial, though, as files can contain
+quotes, commas, and parentheses, which can interfere with the way the
+@code{m4} parser works.  GNU @code{m4} seamlessly concatenates
+the file contents with the next character, even if the included file
+ended in the middle of a comment, string, or macro call.  These
+conditions are only treated as end of file errors if specified as input
+files on the command line.
+
+In GNU @code{m4}, an alternative method of reading files is
+using @code{undivert} (@pxref{Undivert}) on a named file.

+
+@node Diversions
+@chapter Diverting and undiverting output
+
+@cindex deferring output
+Diversions are a way of temporarily saving output.  The output of
+@code{m4} can at any time be diverted to a temporary file, and be
+reinserted into the output stream, @dfn{undiverted}, again at a later
+time.
+
+@cindex @env{TMPDIR}
+Numbered diversions are counted from 0 upwards, diversion number 0
+being the normal output stream.  GNU
+@code{m4} tries to keep diversions in memory.  However, there is a
+limit to the overall memory usable by all diversions taken together
+(512K, currently).  When this maximum is about to be exceeded,
+a temporary file is opened to receive the contents of the biggest
+diversion still in memory, freeing this memory for other diversions.
+When creating the temporary file, @code{m4} honors the value of the
+environment variable @env{TMPDIR}, and falls back to @file{/tmp}.
+Thus, the amount of available disk space provides the only real limit on
+the number and aggregate size of diversions.

+Diversions make it possible to generate output in a different order than

+macro appears in the output prior to the expansion of a dependent macro,
+regardless of which order the two macros were invoked in the user's

+If output is diverted to a negative diversion, it is simply discarded.
+This can be used to suppress unwanted output.  A common example of

+
+@cindex GNU extensions
+Traditional implementations only supported ten diversions.  But as a

+
+@example
+divert(eval(`1<<28'))world
+divert(`2')hello

+@end example
+
+Note that @code{divert} is an English word, but also an active macro

+normal text and be unintentionally swallowed as a macro invocation.  One
+way to avoid this is to use the @option{-P} option to rename all
+builtins (@pxref{Operation modes, , Invoking m4}).  Another is to write
+a wrapper that requires a parameter to be recognized.

+@cindex inclusion, of files
+@cindex GNU extensions
+As a GNU extension, @var{diversions} may contain non-numeric
+strings, which are treated as the names of files to copy into the output
+without expansion.  A warning is issued if a file could not be opened.
+
+The expansion of @code{undivert} is void.
+@end deffn
+
+@example
+divert(`1')
+This text is diverted.

+This text is not diverted.
+@result{}This text is not diverted.
+undivert(`1')
+@result{}
+@result{}This text is diverted.
+@result{}
+@end example
+
+Notice the last two blank lines.  One of them comes from the newline
+following @code{undivert}, the other from the newline that followed the
+@code{divert}!  A diversion often starts with a blank line like this.
+
+When diverted text is undiverted, it is @emph{not} reread by @code{m4},
+but rather copied directly to the current output, and it is therefore
+not an error to undivert into a diversion.  Undiverting the empty string
+is the same as specifying diversion 0; in either case nothing happens
+since the output has already been flushed.

+@example
+divert(`1')diverted text

+This text is diverted first.
+divert(`0')undivert(`1')dnl

+@end example
+
+Attempts to undivert the current diversion are silently ignored.  Thus,

+@cindex inclusion, of files
+GNU @code{m4} allows named files to be undiverted.  Given a

+the file @file{foo} contains:

+Character translation is done with @code{translit}:

+Expands to @var{string}, with each character that occurs in
+@var{chars} translated into the character from @var{replacement} with
+the same index.
+
+If @var{replacement} is shorter than @var{chars}, the excess characters
+of @var{chars} are deleted from the expansion; if @var{chars} is
+shorter, the excess characters in @var{replacement} are silently
+ignored.  If @var{replacement} is omitted, all characters in
+@var{string} that are present in @var{chars} are deleted from the
+expansion.  If a character appears more than once in @var{chars}, only
+the first instance is used in making the translation.  Only a single
+translation pass is made, even if characters in @var{replacement} also
+appear in @var{chars}.
+
+As a GNU extension, both @var{chars} and @var{replacement} can
+contain character-ranges, e.g., @samp{a-z} (meaning all lowercase
+letters) or @samp{0-9} (meaning all digits).  To include a dash @samp{-}
+in @var{chars} or @var{replacement}, place it first or last in the
+entire string, or as the last character of a range.  Back-to-back ranges
+can share a common endpoint.  It is not an error for the last character
+in the range to be `larger' than the first.  In that case, the range
+runs backwards, i.e., @samp{9-0} means the string @samp{9876543210}.
+The expansion of a range is dependent on the underlying encoding of
+characters, so using ranges is not always portable between machines.

+
+In the @sc{ascii} encoding, the first example deletes all uppercase
+letters, the second converts lowercase to uppercase, and the third
+`mirrors' all uppercase letters, while converting them to lowercase.
+The two first cases are by far the most common, even though they are not
+portable to @sc{ebcdic} or other encodings.  The fourth example shows a
+range ending in @samp{-}, as well as back-to-back ranges.  The final
+example shows that @samp{a} is mapped to @samp{b}, not @samp{c}; the
+resulting @samp{b} is not further remapped to @samp{g}; the @samp{d} and
+@samp{e} are swapped, and the @samp{f} is discarded.

+
+The parts of @var{string} that are not covered by any match of
+@var{regexp} are copied to the expansion.  Whenever a match is found, the
+search proceeds from the end of the match, so a character from
+@var{string} will never be substituted twice.  If @var{regexp} matches a
+string of zero length, the start position for the search is incremented,
+to avoid infinite loops.
+
+When a replacement is to be made, @var{replacement} is inserted into

+Here is a slightly more realistic example, which capitalizes individual

+
+@deffn Composite upcase (@var{text})
+@deffnx Composite downcase (@var{text})
+@deffnx Composite capitalize (@var{text})

+to lower case, and @code{capitalize} changes the first character of each
+word to upper case and the remaining characters to lower case.

+downcase(`GNUs not Unix')
+@result{}gnus not unix
+capitalize(`GNUs not Unix')
+@result{}Gnus Not Unix
+@end example
+
+Now for the implementation.  There is a helper macro @code{_capitalize}
+which puts only its first word in mixed case.  Then @code{capitalize}
+merely parses out the words, and replaces them with an invocation of
+@code{_capitalize}.  (As presented here, the @code{capitalize} macro has
+some subtle flaws.  You should try to see if you can find and correct
+them; or @pxref{Improved capitalize, , Answers}).

+@result{}divert`'dnl
+@end example
+
+While @code{regexp} replaces the whole input with the replacement as
+soon as there is a match, @code{patsubst} replaces each
+@emph{occurrence} of a match and preserves non-matching pieces:
+
+@example
+define(`patreg',

+regexp($@@)')dnl
+patreg(`bar foo baz Foo', `foo\|Foo', `FOO')

+All binary operators, except exponentiation, are left associative.  C
+operators that perform variable assignment, such as @samp{+=} or
+@samp{--}, are not implemented, since @code{eval} only operates on
+constants, not variables.  Attempting to use them results in an error.
+However, since traditional implementations treated @samp{=} as an
+undocumented alias for @samp{==} as opposed to an assignment operator,
+this usage is supported as a special case.  Be aware that a future
+version of GNU M4 may support assignment semantics as an
+extension when POSIX mode is not requested, and that using
+@samp{=} to check equality is not portable.

+@end example
+
+Note that some older @code{m4} implementations use @samp{^} as an
+alternate operator for the exponentiation, although POSIX
+requires the C behavior of bitwise exclusive-or.  The precedence of the
+negation operators, @samp{~} and @samp{!}, was traditionally lower than
+equality.  The unary operators could not be used reliably more than once
+on the same term without intervening parentheses.  The traditional
+precedence of the equality operators @samp{==} and @samp{!=} was
+identical instead of lower than the relational operators such as
+@samp{<}, even through GNU M4 1.4.8.  Starting with version
+1.4.9, GNU M4 correctly follows POSIX precedence
+rules.  M4 scripts designed to be portable between releases must be
+aware that parentheses may be required to enforce C precedence rules.
+Likewise, division by zero, even in the unused branch of a
+short-circuiting operator, is not always well-defined in other
+implementations.
+
+Following are some examples where the current version of M4 follows C
+precedence rules, but where older versions and some other
+implementations of @code{m4} require explicit parentheses to get the
+correct result:
+
+@example
+eval(`1 == 2 > 0')

+eval(`(1 == 2) > 0')
+@result{}0
+eval(`! 0 * 2')

+
+@cindex GNU extensions
+As a GNU extension, the operator @samp{**} performs integral
+exponentiation.  The operator is right-associative, and if evaluated,
+the exponent must be non-negative, and at least one of the arguments
+must be non-zero, or a warning is issued.
+
+@example
+eval(`2 ** 3 ** 2')
+@result{}512
+eval(`(2 ** 3) ** 2')
+@result{}64
+eval(`0 ** 1')
+@result{}0

+@result{}
+@end example
+
+Within @var{expression}, (but not @var{radix} or @var{width}), numbers
+without a special prefix are decimal.  A simple @samp{0} prefix
+introduces an octal number.  @samp{0x} introduces a hexadecimal number.
+As GNU extensions, @samp{0b} introduces a binary number.
+@samp{0r} introduces a number expressed in any radix between 1 and 36:
+the prefix should be immediately followed by the decimal expression of
+the radix, a colon, then the digits making the number.  For radix 1,
+leading zeros are ignored, and all remaining digits must be @samp{1};
+for all other radices, the digits are @samp{0}, @samp{1}, @samp{2},
+@dots{}.  Beyond @samp{9}, the digits are @samp{a}, @samp{b} @dots{} up
+to @samp{z}.  Lower and upper case letters can be used interchangeably
+in numbers prefixes and as number digits.
+
+Parentheses may be used to group subexpressions whenever needed.  For the
+relational operators, a true relation returns @code{1}, and a false
+relation return @code{0}.
+
+Here are a few examples of use of @code{eval}.
+
+@example
+eval(`-3 * 5')
+@result{}-15
+eval(`-99 / 10')
+@result{}-9
+eval(`-99 % 10')
+@result{}-9
+eval(`99 % -10')

+eval(`foo / 6')
+@error{}m4:stdin:11: bad expression in eval: foo / 6
+@result{}
+eval(foo / 6)
+@result{}111
+@end example
+
+As the last two lines show, @code{eval} does not handle macro
+names, even if they expand to a valid expression (or part of a valid
+expression).  Therefore all macros must be expanded before they are
+passed to @code{eval}.
+
+Some calculations are not portable to other implementations, since they
+have undefined semantics in C, but GNU @code{m4} has
+well-defined behavior on overflow.  When shifting, an out-of-range shift
+amount is implicitly brought into the range of 32-bit signed integers
+using an implicit bit-wise and with 0x1f).
+
+@example
+define(`max_int', eval(`0x7fffffff'))
+@result{}
+define(`min_int', incr(max_int))
+@result{}
+eval(min_int` < 0')
+@result{}1
+eval(max_int` > 0')
+@result{}1
+ifelse(eval(min_int` / -1'), min_int, `overflow occurred')

+@result{}0
+eval(`-4 >> 1')
+@result{}-2
+eval(`-4 >> 33')
+@result{}-2
+@end example
+
+If @var{radix} is specified, it specifies the radix to be used in the
+expansion.  The default radix is 10; this is also the case if
+@var{radix} is the empty string.  A warning results if the radix is
+outside the range of 1 through 36, inclusive.  The result of @code{eval}
+is always taken to be signed.  No radix prefix is output, and for
+radices greater than 10, the digits are lower case.  The @var{width}
+argument specifies the minimum output width, excluding any negative
+sign.  The result is zero-padded to extend the expansion to the
+requested width.  A warning results if the width is negative.  If
+@var{radix} or @var{width} is out of bounds, the expansion of
+@code{eval} is empty.
+

+@section Determining the platform
+
+@cindex platform macros
+Sometimes it is desirable for an input file to know which platform
+@code{m4} is running on.  GNU @code{m4} provides several
+macros that are predefined to expand to the empty string; checking for
+their existence will confirm platform details.
+
+@deffn {Optional builtin} __gnu__
+@deffnx {Optional builtin} __os2__
+@deffnx {Optional builtin} os2
+@deffnx {Optional builtin} __unix__
+@deffnx {Optional builtin} unix
+@deffnx {Optional builtin} __windows__
+@deffnx {Optional builtin} windows
+Each of these macros is conditionally defined as needed to describe the
+environment of @code{m4}.  If defined, each macro expands to the empty
+string.  For now, these macros silently ignore all arguments, but in a
+future release of M4, they might warn if arguments are present.
+@end deffn
+
+When GNU extensions are in effect (that is, when you did not
+use the @option{-G} option, @pxref{Limits control, , Invoking m4}),
+GNU @code{m4} will define the macro @code{@w{__gnu__}} to
+expand to the empty string.
+
+@example
+$ @kbd{m4}
+__gnu__
+@result{}
+__gnu__(`ignored')
+@result{}
+Extensions are ifdef(`__gnu__', `active', `inactive')
+@result{}Extensions are active

+
+@comment options: -G
+@example
+$ @kbd{m4 -G}
+__gnu__
+@result{}__gnu__
+__gnu__(`ignored')
+@result{}__gnu__(ignored)
+Extensions are ifdef(`__gnu__', `active', `inactive')
+@result{}Extensions are inactive
+@end example
+
+On UNIX systems, GNU @code{m4} will define @code{@w{__unix__}}
+by default, or @code{unix} when the @option{-G} option is specified.
+
+On native Windows systems, GNU @code{m4} will define
+@code{@w{__windows__}} by default, or @code{windows} when the
+@option{-G} option is specified.
+
+On OS/2 systems, GNU @code{m4} will define @code{@w{__os2__}}
+by default, or @code{os2} when the @option{-G} option is specified.
+
+If GNU @code{m4} does not provide a platform macro for your system,
+please report that as a bug.

+@node Syscmd
+@section Executing simple commands
+
+Any shell command can be executed, using @code{syscmd}:
+
+@deffn Builtin syscmd (@var{shell-command})
+Executes @var{shell-command} as a shell command.
+
+The expansion of @code{syscmd} is void, @emph{not} the output from
+@var{shell-command}!  Output or error messages from @var{shell-command}
+are not read by @code{m4}.  @xref{Esyscmd}, if you need to process the
+command output.
+
+Prior to executing the command, @code{m4} flushes its buffers.
+The default standard input, output and error of @var{shell-command} are
+the same as those of @code{m4}.
+
+By default, the @var{shell-command} will be used as the argument to the
+@option{-c} option of the @command{/bin/sh} shell (or the version of
+@command{sh} specified by @samp{command -p getconf PATH}, if your system
+supports that).  If you prefer a different shell, the
+@command{configure} script can be given the option
+@option{--with-syscmd-shell=@var{location}} to set the location of an
+alternative shell at GNU @code{m4} installation; the
+alternative shell must still support @option{-c}.
+
+The macro @code{syscmd} is recognized only with parameters.
+@end deffn
+
+@example
+define(`foo', `FOO')
+@result{}
+syscmd(`echo foo')
+@result{}foo
+@result{}
+@end example
+
+Note how the expansion of @code{syscmd} keeps the trailing newline of
+the command, as well as using the newline that appeared after the macro.
+
+The following is an example of @var{shell-command} using the same
+standard input as @code{m4}:
+
+@comment ignore
+@example
+$ @kbd{echo "m4wrap(\`syscmd(\`cat')')" | m4}
+@result{}
+@end example
+
+@ignore
+@comment If the user types the example below with stdin being an
+@comment interactive terminal, then cat will hang waiting for additional
+@comment input after m4 has exited.  But the testsuite is using a pipe
+@comment for stdin.  Hence, we have two versions - the one we feed the
+@comment testsuite below, and the one we display to the user above that
+@comment more accurately shows what the testsuite is really doing but
+@comment which the testsuite cannot parse.
+
+@example
+m4wrap(`syscmd(`cat')')
+@result{}
+^D
+@end example
+@end ignore
+
+It tells @code{m4} to read all of its input before executing the wrapped
+text, then hand a valid (albeit emptied) pipe as standard input for the
+@code{cat} subcommand.  Therefore, you should be careful when using
+standard input (either by specifying no files, or by passing @samp{-} as
+a file name on the command line, @pxref{Command line files, , Invoking
+m4}), and also invoking subcommands via @code{syscmd} or @code{esyscmd}
+that consume data from standard input.  When standard input is a
+seekable file, the subprocess will pick up with the next character not
+yet processed by @code{m4}; when it is a pipe or other non-seekable
+file, there is no guarantee how much data will already be buffered by
+@code{m4} and thus unavailable to the child.
+
+@node Esyscmd
+@section Reading the output of commands
+
+@cindex GNU extensions
+If you want @code{m4} to read the output of a shell command, use
+@code{esyscmd}:
+
+@deffn Builtin esyscmd (@var{shell-command})
+Expands to the standard output of the shell command
+@var{shell-command}.
+
+Prior to executing the command, @code{m4} flushes its buffers.
+The default standard input and standard error of @var{shell-command} are
+the same as those of @code{m4}.  The error output of @var{shell-command}
+is not a part of the expansion: it will appear along with the error
+output of @code{m4}.
+
+By default, the @var{shell-command} will be used as the argument to the
+@option{-c} option of the @command{/bin/sh} shell (or the version of
+@command{sh} specified by @samp{command -p getconf PATH}, if your system
+supports that).  If you prefer a different shell, the
+@command{configure} script can be given the option
+@option{--with-syscmd-shell=@var{location}} to set the location of an
+alternative shell at GNU @code{m4} installation; the
+alternative shell must still support @option{-c}.
+
+The macro @code{esyscmd} is recognized only with parameters.
+@end deffn
+
+@example
+define(`foo', `FOO')
+@result{}
+esyscmd(`echo foo')
+@result{}FOO
+@result{}
+@end example
+
+Note how the expansion of @code{esyscmd} keeps the trailing newline of
+the command, as well as using the newline that appeared after the macro.
+
+Just as with @code{syscmd}, care must be exercised when sharing standard
+input between @code{m4} and the child process of @code{esyscmd}.

+
+@code{sysval} results in 127 if there was a problem executing the
+command, for example, if the system-imposed argument length is exceeded,
+or if there were not enough resources to fork.  It is not possible to
+distinguish between failed execution and successful execution that had
+an exit status of 127, unless there was output from the child process.
+
+On UNIX platforms, where it is possible to detect when command execution
+is terminated by a signal, rather than a normal exit, the result is the
+signal number shifted left by eight bits.
+
+@comment This test has difficulties being portable, even on platforms
+@comment where syscmd invokes /bin/sh.  Kill is not portable with signal
+@comment names.  According to autoconf, the only portable signal numbers
+@comment are 1 (HUP), 2 (INT), 9 (KILL), 13 (PIPE) and 15 (TERM).  But
+@comment all shells handle SIGINT, and ksh handles HUP (as in, the shell
+@comment exits normally rather than letting the signal terminate it).
+@comment Also, TERM is flaky, as it can also kill the running m4 on
+@comment systems where /bin/sh does not create its own process group.
+@comment And PIPE is unreliable, since people tend to run with it
+@comment ignored, with m4 inheriting that choice.  That leaves KILL as
+@comment the only signal we can reliably test, but even that is tricky:
+@comment on Haiku, 'kill -9' actually causes a process to die with

+@node Mkstemp
+@section Making temporary files
+
+@cindex temporary file names
+@cindex files, names of temporary
+Commands specified to @code{syscmd} or @code{esyscmd} might need a
+temporary file, for output or for some other purpose.  There is a
+builtin macro, @code{mkstemp}, for making a temporary file:
+
+@deffn Builtin mkstemp (@var{template})
+@deffnx Builtin maketemp (@var{template})
+Expands to the quoted name of a new, empty file, made from the string
+@var{template}, which should end with the string @samp{XXXXXX}.  The six
+@samp{X} characters are then replaced with random characters matching
+the regular expression @samp{a-zA-Z0-9._-}, in order to make the file
+name unique.  If fewer than six @samp{X} characters are found at the end
+of @code{template}, the result will be longer than the template.  The
+created file will have access permissions as if by @kbd{chmod =rw,go=},
+meaning that the current umask of the @code{m4} process is taken into
+account, and at most only the current user can read and write the file.
+
+The traditional behavior, standardized by POSIX, is that
+@code{maketemp} merely replaces the trailing @samp{X} with the process
+id, without creating a file or quoting the expansion, and without
+ensuring that the resulting
+string is a unique file name.  In part, this means that using the same
+@var{template} twice in the same input file will result in the same
+expansion.  This behavior is a security hole, as it is very easy for
+another process to guess the name that will be generated, and thus
+interfere with a subsequent use of @code{syscmd} trying to manipulate
+that file name.  Hence, POSIX has recommended that all new
+implementations of @code{m4} provide the secure @code{mkstemp} builtin,
+and that users of @code{m4} check for its existence.
+
+The expansion is void and an error issued if a temporary file could
+not be created.
+
+The macros @code{mkstemp} and @code{maketemp} are recognized only with
+parameters.
+@end deffn
+
+If you try this next example, you will most likely get different output
+for the two file names, since the replacement characters are randomly
+chosen:
+
+@comment ignore
+@example
+$ @kbd{m4}
+define(`tmp', `oops')
+@result{}
+maketemp(`/tmp/fooXXXXXX')
+@result{}/tmp/fooa07346
+ifdef(`mkstemp', `define(`maketemp', defn(`mkstemp'))',
+      `define(`mkstemp', defn(`maketemp'))dnl
+errprint(`warning: potentially insecure maketemp implementation
+')')
+@result{}
+mkstemp(`doc')
+@result{}docQv83Uw
+@end example
+
+@cindex GNU extensions
+Unless you use the @option{--traditional} command line option (or
+@option{-G}, @pxref{Limits control, , Invoking m4}), the GNU
+version of @code{maketemp} is secure.  This means that using the same
+template to multiple calls will generate multiple files.  However, we
+recommend that you use the new @code{mkstemp} macro, introduced in
+GNU M4 1.4.8, which is secure even in traditional mode.  Also,
+as of M4 1.4.11, the secure implementation quotes the resulting file
+name, so that you are guaranteed to know what file was created even if
+the random file name happens to match an existing macro.  Notice that
+this example is careful to use @code{defn} to avoid unintended expansion
+of @samp{foo}.
+
+@example
+$ @kbd{m4}
+define(`foo', `errprint(`oops')')
+@result{}

+You can print error messages using @code{errprint}:
+
+@deffn Builtin errprint (@var{message}, @dots{})
+Prints @var{message} and the rest of the arguments to standard error,
+separated by spaces.  Standard error is used, regardless of the
+@option{--debugfile} option (@pxref{Debugging options, , Invoking m4}).
+
+The expansion of @code{errprint} is void.
+The macro @code{errprint} is recognized only with parameters.

+@error{}12 3
+@result{}
+@end example
+
+A trailing newline is @emph{not} printed automatically, so it should be
+supplied as part of the argument, as in the example.  Unfortunately, the
+exact output of @code{errprint} is not very portable to other @code{m4}
+implementations: POSIX requires that all arguments be printed,
+but some implementations of @code{m4} only print the first.
+Furthermore, some BSD implementations always append a newline
+for each @code{errprint} call, regardless of whether the last argument
+already had one, and POSIX is silent on whether this is
+acceptable.
+
+@node Location
+@section Printing current location
+
+@cindex location, input
+@cindex input location
+To make it possible to specify the location of an error, three
+utility builtins exist:
+
+@deffn Builtin __file__
+@deffnx Builtin __line__
+@deffnx Builtin __program__
+Expand to the quoted name of the current input file, the
+current input line number in that file, and the quoted name of the
+current invocation of @code{m4}.
+@end deffn
+
+@example
+errprint(__program__:__file__:__line__: `input error
+')
+@error{}m4:stdin:1: input error
+@result{}
+@end example
+
+Line numbers start at 1 for each file.  If the file was found due to the
+@option{-I} option or @env{M4PATH} environment variable, that is
+reflected in the file name.  The syncline option (@option{-s},
+@pxref{Preprocessor features, , Invoking m4}), and the
+@samp{f} and @samp{l} flags of @code{debugmode} (@pxref{Debug Levels}),
+also use this notion of current file and line.  Redefining the three
+location macros has no effect on syncline, debug, warning, or error
+message output.
+
+This example reuses the file @file{incl.m4} mentioned earlier
+(@pxref{Include}):
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+define(`foo', ``$0' called at __file__:__line__')
+@result{}
+foo
+@result{}foo called at stdin:2
+include(`incl.m4')
+@result{}Include file start
+@result{}foo called at examples/incl.m4:2
+@result{}Include file end
+@result{}
+@end example
+
+The location of macros invoked during the rescanning of macro expansion
+text corresponds to the location in the file where the expansion was
+triggered, regardless of how many newline characters the expansion text
+contains.  As of GNU M4 1.4.8, the location of text wrapped
+with @code{m4wrap} (@pxref{M4wrap}) is the point at which the
+@code{m4wrap} was invoked.  Previous versions, however, behaved as
+though wrapped text came from line 0 of the file ``''.
+
+@example
+define(`echo', `$@@')
+@result{}
+define(`foo', `echo(__line__
+__line__)')
+@result{}
+echo(__line__
+__line__)
+@result{}4
+@result{}5
+m4wrap(`foo
+')
+@result{}
+foo(errprint(__line__
+__line__
+))
+@error{}8
+@error{}9
+@result{}8
+@result{}8
+__line__
+@result{}11
+m4wrap(`__line__
+')
+@result{}
+^D
+@result{}12
+@result{}6
+@result{}6
+@end example
+
+The @code{@w{__program__}} macro behaves like @samp{$0} in shell
+terminology.  If you invoke @code{m4} through an absolute path or a link
+with a different spelling, rather than by relying on a @env{PATH} search
+for plain @samp{m4}, it will affect how @code{@w{__program__}} expands.
+The intent is that you can use it to produce error messages with the
+same formatting that @code{m4} produces internally.  It can also be used
+within @code{syscmd} (@pxref{Syscmd}) to pick the same version of
+@code{m4} that is currently running, rather than whatever version of
+@code{m4} happens to be first in @env{PATH}.  It was first introduced in
+GNU M4 1.4.6.
+
+@node M4exit
+@section Exiting from @code{m4}
+
+@cindex exiting from @code{m4}
+@cindex status, setting @code{m4} exit
+If you need to exit from @code{m4} before the entire input has been
+read, you can use @code{m4exit}:
+
+@deffn Builtin m4exit (@dvar{code, 0})
+Causes @code{m4} to exit, with exit status @var{code}.  If @var{code} is
+left out, the exit status is zero.  If @var{code} cannot be parsed, or
+is outside the range of 0 to 255, the exit status is one.  No further
+input is read, and all wrapped and diverted text is discarded.
+@end deffn
+
+@example
+m4wrap(`This text is lost due to `m4exit'.')
+@result{}
+divert(`1') So is this.
+divert
+@result{}
+m4exit And this is never read.
+@end example
+
+A common use of this is to abort processing:
+
+@deffn Composite fatal_error (@var{message})
+Abort processing with an error message and non-zero status.  Prefix
+@var{message} with details about where the error occurred, and print the
+resulting string to standard error.
+@end deffn
+
+@comment status: 1
+@example
+define(`fatal_error',
+       `errprint(__program__:__file__:__line__`: fatal error: $*
+')m4exit(`1')')
+@result{}
+fatal_error(`this is a BAD one, buster')
+@error{}m4:stdin:4: fatal error: this is a BAD one, buster
+@end example
+
+After this macro call, @code{m4} will exit with exit status 1.  This macro
+is only intended for error exits, since the normal exit procedures are
+not followed, i.e., diverted text is not undiverted, and saved text
+(@pxref{M4wrap}) is not reread.  (This macro could be made more robust
+to earlier versions of @code{m4}.  You should try to see if you can find
+weaknesses and correct them; or @pxref{Improved fatal_error, , Answers}).
+
+Note that it is still possible for the exit status to be different than
+what was requested by @code{m4exit}.  If @code{m4} detects some other
+error, such as a write error on standard output, the exit status will be
+non-zero even if @code{m4exit} requested zero.
+
+If standard input is seekable, then the file will be positioned at the
+next unread character.  If it is a pipe or other non-seekable file,
+then there are no guarantees how much data @code{m4} might have read
+into buffers, and thus discarded.
+
+@node Frozen files
+@chapter Fast loading of frozen state
+
+Some bigger @code{m4} applications may be built over a common base
+containing hundreds of definitions and other costly initializations.
+Usually, the common base is kept in one or more declarative files,
+which files are listed on each @code{m4} invocation prior to the
+user's input file, or else each input file uses @code{include}.
+
+Reading the common base of a big application, over and over again, may
+be time consuming.  GNU @code{m4} offers some machinery to
+speed up the start of an application using lengthy common bases.

+@cindex reloading a frozen file
+@cindex GNU extensions
+Suppose a user has a library of @code{m4} initializations in
+@file{base.m4}, which is then used with multiple input files:
+
+@comment ignore
+@example
+$ @kbd{m4 base.m4 input1.m4}
+$ @kbd{m4 base.m4 input2.m4}
+$ @kbd{m4 base.m4 input3.m4}
+@end example
+
+Rather than spending time parsing the fixed contents of @file{base.m4}
+every time, the user might rather execute:
+
+@comment ignore
+@example
+$ @kbd{m4 -F base.m4f base.m4}
+@end example
+
+@noindent
+once, and further execute, as often as needed:
+
+@comment ignore
+@example
+$ @kbd{m4 -R base.m4f input1.m4}
+$ @kbd{m4 -R base.m4f input2.m4}
+$ @kbd{m4 -R base.m4f input3.m4}
+@end example
+
+@noindent
+with the varying input.  The first call, containing the @option{-F}
+option, only reads and executes file @file{base.m4}, defining
+various application macros and computing other initializations.
+Once the input file @file{base.m4} has been completely processed, GNU
+@code{m4} produces in @file{base.m4f} a @dfn{frozen} file, that is, a
+file which contains a kind of snapshot of the @code{m4} internal state.
+
+Later calls, containing the @option{-R} option, are able to reload
+the internal state of @code{m4}, from @file{base.m4f},
+@emph{prior} to reading any other input files.  This means
+instead of starting with a virgin copy of @code{m4}, input will be
+read after having effectively recovered the effect of a prior run.
+In our example, the effect is the same as if file @file{base.m4} has
+been read anew.  However, this effect is achieved a lot faster.
+
+Only one frozen file may be created or read in any one @code{m4}
+invocation.  It is not possible to recover two frozen files at once.
+However, frozen files may be updated incrementally, through using
+@option{-R} and @option{-F} options simultaneously.  For example, if
+some care is taken, the command:
+
+@comment ignore
+@example
+$ @kbd{m4 file1.m4 file2.m4 file3.m4 file4.m4}
+@end example
+
+@noindent
+could be broken down in the following sequence, accumulating the same
+output:
+
+@comment ignore
+@example
+$ @kbd{m4 -F file1.m4f file1.m4}
+$ @kbd{m4 -R file1.m4f -F file2.m4f file2.m4}
+$ @kbd{m4 -R file2.m4f -F file3.m4f file3.m4}
+$ @kbd{m4 -R file3.m4f file4.m4}
+@end example
+
+Some care is necessary because not every effort has been made for
+this to work in all cases.  In particular, the trace attribute of
+macros is not handled, nor the current setting of @code{changeword}.
+Currently, @code{m4wrap} and @code{sysval} also have problems.
+Also, interactions for some options of @code{m4}, being used in one call
+and not in the next, have not been fully analyzed yet.  On the other
+end, you may be confident that stacks of @code{pushdef} definitions
+are handled correctly, as well as undefined or renamed builtins, and
+changed strings for quotes or comments.  And future releases of
+GNU M4 will improve on the utility of frozen files.

+When an @code{m4} run is to be frozen, the automatic undiversion

+A frozen file to be reloaded need not reside in the current directory.
+It is looked up the same way as an @code{include} file (@pxref{Search

+@section Frozen file format
+
+@cindex frozen file format
+@cindex file format, frozen file
+Frozen files are sharable across architectures.  It is safe to write
+a frozen file on one machine and read it on another, given that the
+second machine uses the same or newer version of GNU @code{m4}.
+It is conventional, but not required, to give a frozen file the suffix
+of @code{.m4f}.
+
+These are simple (editable) text files, made up of directives,
+each starting with a capital letter and ending with a newline
+(@key{NL}).  Wherever a directive is expected, the character
+@samp{#} introduces a comment line; empty lines are also ignored if they
+are not part of an embedded string.
+In the following descriptions, each @var{len} refers to the length of
+the corresponding strings @var{str} in the next line of input.  Numbers
+are always expressed in decimal.  There are no escape characters.  The
+directives are:
+
+@table @code
+@item C @var{len1} , @var{len2} @key{NL} @var{str1} @var{str2} @key{NL}
+Uses @var{str1} and @var{str2} as the begin-comment and
+end-comment strings.  If omitted, then @samp{#} and @key{NL} are the
+comment delimiters.
+
+@item D @var{number}, @var{len} @key{NL} @var{str} @key{NL}
+Selects diversion @var{number}, making it current, then copy
+@var{str} in the current diversion.  @var{number} may be a negative
+number for a non-existing diversion.  To merely specify an active
+selection, use this command with an empty @var{str}.  With 0 as the
+diversion @var{number}, @var{str} will be issued on standard output
+at reload time.  GNU @code{m4} will not produce the @samp{D}
+directive with non-zero length for diversion 0, but this can be done
+with manual edits.  This directive may
+appear more than once for the same diversion, in which case the
+diversion is the concatenation of the various uses.  If omitted, then
+diversion 0 is current.
+
+@item F @var{len1} , @var{len2} @key{NL} @var{str1} @var{str2} @key{NL}
+Defines, through @code{pushdef}, a definition for @var{str1}
+expanding to the function whose builtin name is @var{str2}.  If the
+builtin does not exist (for example, if the frozen file was produced by
+a copy of @code{m4} compiled with changeword support, but the version
+of @code{m4} reloading was compiled without it), the reload is silent,
+but any subsequent use of the definition of @var{str1} will result in
+a warning.  This directive may appear more than once for the same name,
+and its order, along with @samp{T}, is important.  If omitted, you will
+have no access to any builtins.
+
+@item Q @var{len1} , @var{len2} @key{NL} @var{str1} @var{str2} @key{NL}
+Uses @var{str1} and @var{str2} as the begin-quote and end-quote
+strings.  If omitted, then @samp{`} and @samp{'} are the quote
+delimiters.
+
+@item T @var{len1} , @var{len2} @key{NL} @var{str1} @var{str2} @key{NL}
+Defines, though @code{pushdef}, a definition for @var{str1}
+expanding to the text given by @var{str2}.  This directive may appear
+more than once for the same name, and its order, along with @samp{F}, is
+important.
+
+@item V @var{number} @key{NL}
+Confirms the format of the file.  @code{m4} @value{VERSION} only creates
+and understands frozen files where @var{number} is 1.  This directive
+must be the first non-comment in the file, and may not appear more than
+once.

+Invoking m4}), unless overridden by other command line options.
+
+@itemize @bullet
+@item
+In the @code{$@var{n}} notation for macro arguments, @var{n} can contain
+several digits, while the System V @code{m4} only accepts one digit.
+This allows macros in GNU @code{m4} to take any number of
+arguments, and not only nine (@pxref{Arguments}).
+
+This means that @code{define(`foo', `$11')} is ambiguous between
+implementations.  To portably choose between grabbing the first
+parameter and appending 1 to the expansion, or grabbing the eleventh
+parameter, you can do the following:
+
+@example

+define(`_1', `$1')define(`first1', `_1($@@)1')

+
+@noindent
+Also see the @code{argn} macro (@pxref{Shift}).
+
+@item
+The @code{divert} (@pxref{Divert}) macro can manage more than 9
+diversions.  GNU @code{m4} treats all positive numbers as valid
+diversions, rather than discarding diversions greater than 9.
+
+@item
+Files included with @code{include} and @code{sinclude} are sought in a
+user specified search path, if they are not found in the working
+directory.  The search path is specified by the @option{-I} option and the
+@env{M4PATH} environment variable (@pxref{Search Path}).
+
+@item
+Arguments to @code{undivert} can be non-numeric, in which case the named
+file will be included uninterpreted in the output (@pxref{Undivert}).
+
+@item
+Formatted output is supported through the @code{format} builtin, which
+is modeled after the C library function @code{printf} (@pxref{Format}).
+
+@item
+Searches and text substitution through basic regular expressions are

+@node Incompatibilities
+@section Facilities in System V @code{m4} not in GNU @code{m4}
+
+The version of @code{m4} from System V contains a few facilities that
+have not been implemented in GNU @code{m4} yet.  Additionally,
+POSIX requires some behaviors that GNU @code{m4} has not
+implemented yet.  Relying on these behaviors is non-portable, as a
+future release of GNU @code{m4} may change.
+
+@itemize @bullet
+@item
+POSIX requires support for multiple arguments to @code{defn},
+without any clarification on how @code{defn} behaves when one of the
+multiple arguments names a builtin.  System V @code{m4} and some other
+implementations allow mixing builtins and text macros into a single
+macro.  GNU @code{m4} only supports joining multiple text
+arguments, although a future implementation may lift this restriction to
+behave more like System V@.  The only portable way to join text macros
+with builtins is via helper macros and implicit concatenation of macro
+results.
+
+@item
+POSIX requires an application to exit with non-zero status if
+it wrote an error message to stderr.  This has not yet been consistently
+implemented for the various builtins that are required to issue an error
+(such as @code{eval} (@pxref{Eval}) when an argument cannot be parsed).
+
+@item
+Some traditional implementations only allow reading standard input
+once, but GNU @code{m4} correctly handles multiple instances
+of @samp{-} on the command line.
+
+@item
+POSIX requires @code{m4wrap} (@pxref{M4wrap}) to act in FIFO
+(first-in, first-out) order, but GNU @code{m4} currently uses
+LIFO order.  Furthermore, POSIX states that only the first
+argument to @code{m4wrap} is saved for later evaluation, but
+GNU @code{m4} saves and processes all arguments, with output
+separated by spaces.
+
+@item
+POSIX states that builtins that require arguments, but are
+called without arguments, have undefined behavior.  Traditional
+implementations simply behave as though empty strings had been passed.
+For example, @code{a`'define`'b} would expand to @code{ab}.  But
+GNU @code{m4} ignores certain builtins if they have missing
+arguments, giving @code{adefineb} for the above example.
+
+@item
+Traditional implementations handle @code{define(`f',`1')} (@pxref{Define})
+by undefining the entire stack of previous definitions, and if doing
+@code{undefine(`f')} first.  GNU @code{m4} replaces just the top
+definition on the stack, as if doing @code{popdef(`f')} followed by
+@code{pushdef(`f',`1')}.  POSIX allows either behavior.
+
+@item
+POSIX 2001 requires @code{syscmd} (@pxref{Syscmd}) to evaluate
+command output for macro expansion, but this was a mistake that is
+anticipated to be corrected in the next version of POSIX.
+GNU @code{m4} follows traditional behavior in @code{syscmd}
+where output is not rescanned, and provides the extension @code{esyscmd}
+that does scan the output.
+
+@item
+At one point, POSIX required @code{changequote(@var{arg})}
+(@pxref{Changequote}) to use newline as the close quote, but this was a
+bug, and the next version of POSIX is anticipated to state
+that using empty strings or just one argument is unspecified.
+Meanwhile, the GNU @code{m4} behavior of treating an empty
+end-quote delimiter as @samp{'} is not portable, as Solaris treats it as
+repeating the start-quote delimiter, and BSD treats it as leaving the
+previous end-quote delimiter unchanged.  For predictable results, never
+call changequote with just one argument, or with empty strings for
+arguments.
+
+@item
+At one point, POSIX required @code{changecom(@var{arg},)}
+(@pxref{Changecom}) to make it impossible to end a comment, but this is
+a bug, and the next version of POSIX is anticipated to state
+that using empty strings is unspecified.  Meanwhile, the GNU
+@code{m4} behavior of treating an empty end-comment delimiter as newline
+is not portable, as BSD treats it as leaving the previous end-comment
+delimiter unchanged.  It is also impossible in BSD implementations to
+disable comments, even though that is required by POSIX.  For
+predictable results, never call changecom with empty strings for
+arguments.
+
+@item
+Most implementations of @code{m4} give macros a higher precedence than
+comments when parsing, meaning that if the start delimiter given to
+@code{changecom} (@pxref{Changecom}) starts with a macro name, comments
+are effectively disabled.  POSIX does not specify what the
+precedence is, so this version of GNU @code{m4} parser
+recognizes comments, then macros, then quoted strings.
+
+@item
+Traditional implementations allow argument collection, but not string
+and comment processing, to span file boundaries.  Thus, if @file{a.m4}
+contains @samp{len(}, and @file{b.m4} contains @samp{abc)},
+@kbd{m4 a.m4 b.m4} outputs @samp{3} with traditional @code{m4}, but
+gives an error message that the end of file was encountered inside a
+macro with GNU @code{m4}.  On the other hand, traditional
+implementations do end of file processing for files included with
+@code{include} or @code{sinclude} (@pxref{Include}), while GNU
+@code{m4} seamlessly integrates the content of those files.  Thus
+@code{include(`a.m4')include(`b.m4')} will output @samp{3} instead of
+giving an error.
+
+@item
+Traditional @code{m4} treats @code{traceon} (@pxref{Trace}) without
+arguments as a global variable, independent of named macro tracing.
+Also, once a macro is undefined, named tracing of that macro is lost.
+On the other hand, when GNU @code{m4} encounters
+@code{traceon} without
+arguments, it turns tracing on for all existing definitions at the time,
+but does not trace future definitions; @code{traceoff} without arguments
+turns tracing off for all definitions regardless of whether they were
+also traced by name; and tracing by name, such as with @option{-tfoo} at
+the command line or @code{traceon(`foo')} in the input, is an attribute
+that is preserved even if the macro is currently undefined.
+
+Additionally, while POSIX requires trace output, it makes no
+demands on the formatting of that output.  Parsing trace output is not
+guaranteed to be reliable, even between different releases of
+GNU M4; however, the intent is that any future changes in
+trace output will only occur under the direction of additional
+@code{debugmode} flags (@pxref{Debug Levels}).
+
+@item
+POSIX requires @code{eval} (@pxref{Eval}) to treat all
+operators with the same precedence as C@.  However, earlier versions of
+GNU @code{m4} followed the traditional behavior of other
+@code{m4} implementations, where bitwise and logical negation (@samp{~}
+and @samp{!}) have lower precedence than equality operators; and where
+equality operators (@samp{==} and @samp{!=}) had the same precedence as
+relational operators (such as @samp{<}).  Use explicit parentheses to
+ensure proper precedence.  As extensions to POSIX,
+GNU @code{m4} gives well-defined semantics to operations that
+C leaves undefined, such as when overflow occurs, when shifting negative
+numbers, or when performing division by zero.  POSIX also
+requires @samp{=} to cause an error, but many traditional
+implementations allowed it as an alias for @samp{==}.
+
+@item
+POSIX 2001 requires @code{translit} (@pxref{Translit}) to
+treat each character of the second and third arguments literally.
+However, it is anticipated that the next version of POSIX will
+allow the GNU @code{m4} behavior of treating @samp{-} as a
+range operator.
+
+@item
+POSIX requires @code{m4} to honor the locale environment
+variables of @env{LANG}, @env{LC_ALL}, @env{LC_CTYPE},
+@env{LC_MESSAGES}, and @env{NLSPATH}, but this has not yet been
+implemented in GNU @code{m4}.
+
+@item
+POSIX states that only unquoted leading newlines and blanks
+(that is, space and tab) are ignored when collecting macro arguments.
+However, this appears to be a bug in POSIX, since most
+traditional implementations also ignore all whitespace (formfeed,
+carriage return, and vertical tab).  GNU @code{m4} follows
+tradition and ignores all leading unquoted whitespace.
+
+@item
+@cindex @env{POSIXLY_CORRECT}
+A strictly-compliant POSIX client is not allowed to use
+command-line arguments not specified by POSIX.  However, since
+this version of M4 ignores @env{POSIXLY_CORRECT} and enables the option
+@code{--gnu} by default (@pxref{Limits control, , Invoking m4}), a
+client desiring to be strictly compliant has no way to disable
+GNU extensions that conflict with POSIX when
+directly invoking the compiled @code{m4}.  A future version of
+@code{GNU} M4 will honor the environment variable @env{POSIXLY_CORRECT},
+implicitly enabling @option{--traditional} if it is set, in order to
+allow a strictly-compliant client.  In the meantime, a client needing
+strict POSIX compliance can use the workaround of invoking a
+shell script wrapper, where the wrapper then adds @option{--traditional}
+to the arguments passed to the compiled @code{m4}.

+
+@node Other Incompatibilities
+@section Other incompatibilities
+
+There are a few other incompatibilities between this implementation of
+@code{m4}, and the System V version.
+
+@itemize @bullet
+@item
+GNU @code{m4} implements sync lines differently from System V
+@code{m4}, when text is being diverted.  GNU @code{m4} outputs
+the sync lines when the text is being diverted, and System V @code{m4}
+when the diverted text is being brought back.
+
+The problem is which lines and file names should be attached to text
+that is being, or has been, diverted.  System V @code{m4} regards all
+the diverted text as being generated by the source line containing the
+@code{undivert} call, whereas GNU @code{m4} regards the
+diverted text as being generated at the time it is diverted.
+
+The sync line option is used mostly when using @code{m4} as
+a front end to a compiler.  If a diverted line causes a compiler error,
+the error messages should most probably refer to the place where the
+diversion was made, and not where it was inserted again.
+
+@comment options: -s
+@example
+divert(2)2
+divert(1)1
+divert`'0
+@result{}#line 3 "stdin"
+@result{}0
+^D
+@result{}#line 2 "stdin"
+@result{}1
+@result{}#line 1 "stdin"
+@result{}2
+@end example
+
+The current @code{m4} implementation has a limitation that the syncline
+output at the start of each diversion occurs no matter what, even if the
+previous diversion did not end with a newline.  This goes contrary to
+the claim that synclines appear on a line by themselves, so this
+limitation may be corrected in a future version of @code{m4}.  In the
+meantime, when using @option{-s}, it is wisest to make sure all
+diversions end with newline.
+
+@item
+GNU @code{m4} makes no attempt at prohibiting self-referential
+definitions like:
+
+@example
+define(`x', `x')
+@result{}
+define(`x', `x ')
+@result{}
+@end example
+
+@cindex rescanning
+There is nothing inherently wrong with defining @samp{x} to
+return @samp{x}.  The wrong thing is to expand @samp{x} unquoted,
+because that would cause an infinite rescan loop.
+In @code{m4}, one might use macros to hold strings, as we do for
+variables in other programming languages, further checking them with:
+
+@comment ignore
+@example
+ifelse(defn(`@var{holder}'), `@var{value}', @dots{})
+@end example
+
+@noindent
+In cases like this one, an interdiction for a macro to hold its own name
+would be a useless limitation.  Of course, this leaves more rope for the
+GNU @code{m4} user to hang himself!  Rescanning hangs may be
+avoided through careful programming, a little like for endless loops in
+traditional programming languages.

+@section Solution for @code{exch}
+
+The @code{exch} macro (@pxref{Arguments}) as presented requires clients
+to double quote their arguments.  A nicer definition, which lets
+clients follow the rule of thumb of one level of quoting per level of
+parentheses, involves adding quotes in the definition of @code{exch}, as
+follows:
+
+@example
+define(`exch', ``$2', `$1'')
+@result{}
+define(exch(`expansion text', `macro'))
+@result{}
+macro
+@result{}expansion text
+@end example
+
+@node Improved forloop
+@section Solution for @code{forloop}
+
+The @code{forloop} macro (@pxref{Forloop}) as presented earlier can go
+into an infinite loop if given an iterator that is not parsed as a macro
+name.  It does not do any sanity checking on its numeric bounds, and
+only permits decimal numbers for bounds.  Here is an improved version,
+shipped as @file{m4-@value{VERSION}/@/examples/@/forloop2.m4}; this
+version also optimizes overhead by calling four macros instead of six
+per iteration (excluding those in @var{text}), by not dereferencing the
+@var{iterator} in the helper @code{@w{_forloop}}.
+
+@comment examples
+@example
+$ @kbd{m4 -d -I examples}

+@result{}  `define(`$1', `$2')$4`'ifelse(`$2', `$3', `',

+@result{} 0xa 0xb 0xc
+forloop(`i', `a', `b', `non-numeric bounds')
+@error{}m4:stdin:6: bad expression in eval (bad input): (a) <= (b)
+@result{}
+@end example
+
+One other change to notice is that the improved version used @samp{_$0}
+rather than @samp{_foreach} to invoke the helper routine.  In general,
+this is a good practice to follow, because then the set of macros can be
+uniformly transformed.  The following example shows a transformation
+that doubles the current quoting and appends a suffix @samp{2} to each
+transformed macro.  If @code{foreach} refers to the literal
+@samp{_foreach}, then @code{foreach2} invokes @code{_foreach} instead of
+the intended @code{_foreach2}, and the mixing of quoting paradigms leads
+to an infinite recursion loop in this example.

+@end example
+
+One more optimization is still possible.  Instead of repeatedly
+assigning a variable then invoking or dereferencing it, it is possible
+to pass the current iterator value as a single argument.  Coupled with
+@code{curry} if other arguments are needed (@pxref{Composition}), or
+with helper macros if the argument is needed in more than one place in
+the expansion, the output can be generated with three, rather than four,
+macros of overhead per iteration.  Notice how the file
+@file{m4-@value{VERSION}/@/examples/@/forloop3.m4} rearranges the
+arguments of the helper @code{_forloop} to take two arguments that are
+placed around the current value.  By splitting a balanced set of
+parantheses across multiple arguments, the helper macro can now be
+shared by @code{forloop} and the new @code{forloop_arg}.

+@cindex quadratic behavior, avoiding
+@cindex avoiding quadratic behavior
+Each successive iteration was adding more quoted @code{shift}
+invocations, and the entire list contents were passing through every
+iteration.  In general, when recursing, it is a good idea to make the
+recursion use fewer arguments, rather than adding additional quoted
+uses of @code{shift}.  By doing so, @code{m4} uses less memory, invokes
+fewer macros, is less likely to run into machine limits, and most

+be found in @file{m4-@value{VERSION}/@/examples/@/foreachq2.m4}:

+
+Note that the fixed version calls unquoted helper macros in
+@code{@w{_foreachq}} to trim elements immediately; those helper macros
+in turn must re-supply the layer of quotes lost in the macro invocation.
+Contrast the use of @code{@w{_arg1q}}, which quotes the first list
+element, with @code{@w{_arg1}} of the earlier implementation that
+returned the first list element directly.  Additionally, by calling the
+helper method immediately, the @samp{defn(`@var{iterator}')} no longer
+contains unexpanded macros.
+
+The astute m4 programmer might notice that the solution above still uses
+more memory and macro invocations, and thus more time, than strictly
+necessary.  Note that @samp{$2}, which contains an arbitrarily long
+quoted list, is expanded and rescanned three times per iteration of
+@code{_foreachq}. Furthermore, every iteration of the algorithm
+effectively unboxes then reboxes the list, which costs a couple of macro
+invocations.  It is possible to rewrite the algorithm for a bit more
+speed by swapping the order of the arguments to @code{_foreachq} in
+order to operate on an unboxed list in the first place, and by using the
+fixed-length @samp{$#} instead of an arbitrary length list as the key to
+end recursion.  The result is an overhead of six macro invocations per
+loop (excluding any macros in @var{text}), instead of eight.  This
+alternative approach is available as

+
+In the current version of M4, every instance of @samp{$@@} is rescanned
+as it is encountered.  Thus, the @file{foreachq3.m4} alternative uses
+much less memory than @file{foreachq2.m4}, and executes as much as 10%
+faster, since each iteration encounters fewer @samp{$@@}.  However, the
+implementation of rescanning every byte in @samp{$@@} is quadratic in
+the number of bytes scanned (for example, making the broken version in
+@file{foreachq.m4} cubic, rather than quadratic, in behavior).  A future
+release of M4 will improve the underlying implementation by reusing
+results of previous scans, so that both styles of @code{foreachq} can
+become linear in the number of bytes scanned.  Notice how the
+implementation injects an empty argument prior to expanding @samp{$2}
+within @code{foreachq}; the helper macro @code{_foreachq} then ignores
+the third argument altogether, and ends recursion when there are three
+arguments left because there was nothing left to pass through
+@code{shift}.  Thus, each iteration only needs one @code{ifelse}, rather
+than the two conditionals used in the version from @file{foreachq2.m4}.

+@cindex nine arguments, more than
+@cindex more than nine arguments
+@cindex arguments, more than nine
+So far, all of the implementations of @code{foreachq} presented have
+been quadratic with M4 1.4.x.  But @code{forloop} is linear, because
+each iteration parses a constant amount of arguments.  So, it is
+possible to design a variant that uses @code{forloop} to do the
+iteration, then uses @samp{$@@} only once at the end, giving a linear
+result even with older M4 implementations.  This implementation relies
+on the GNU extension that @samp{$10} expands to the tenth
+argument rather than the first argument concatenated with @samp{0}.  The
+trick is to define an intermediate macro that repeats the text
+@code{m4_define(`$1', `$@var{n}')$2`'}, with @samp{n} set to successive
+integers corresponding to each argument.  The helper macro
+@code{_foreachq_} is needed in order to generate the literal sequences
+such as @samp{$1} into the intermediate macro, rather than expanding
+them as the arguments of @code{_foreachq}.  With this approach, no
+@code{shift} calls are even needed!  Even though there are seven macros
+of overhead per iteration instead of six in @file{foreachq3.m4}, the
+linear scaling is apparent at relatively small list sizes.  However,
+this approach will need adjustment when a future version of M4 follows
+POSIX by no longer treating @samp{$10} as the tenth argument;
+the anticipation is that @samp{$@{10@}} can be used instead, although
+that alternative syntax is not yet supported.

+
+It is likewise possible to write a variant of @code{foreach} that
+performs in linear time on M4 1.4.x; the easiest method is probably
+writing a version of @code{foreach} that unboxes its list, then invokes
+@code{_foreachq} as previously defined in @file{foreachq4.m4}.
+
+In summary, recursion over list elements is trickier than it appeared at
+first glance, but provides a powerful idiom within @code{m4} processing.
+As a final demonstration, both list styles are now able to handle
+several scenarios that would wreak havoc on one or both of the original
+implementations.  This points out one other difference between the
+list styles.  @code{foreach} evaluates unquoted list elements only once,
+in preparation for calling @code{@w{_foreach}}, similary for
+@code{foreachq} as provided by @file{foreachq3.m4} or
+@file{foreachq4.m4}.  But
+@code{foreachq}, as provided by @file{foreachq2.m4},
+evaluates unquoted list elements twice while visiting the first list
+element, once in @code{@w{_arg1q}} and once in @code{@w{_rest}}.  When
+deciding which list style to use, one must take into account whether
+repeating the side effects of unquoted list elements will have any
+detrimental effects.

+@node Improved copy
+@section Solution for @code{copy}
+
+The macro @code{copy} presented above
+is unable to handle builtin tokens with M4 1.4.x, because it tries to
+pass the builtin token through the macro @code{curry}, where it is
+silently flattened to an empty string (@pxref{Composition}).  Rather
+than using the problematic @code{curry} to work around the limitation
+that @code{stack_foreach} expects to invoke a macro that takes exactly
+one argument, we can write a new macro that lets us form the exact
+two-argument @code{pushdef} call sequence needed, so that we are no
+longer passing a builtin token through a text macro.
+
+@deffn Composite stack_foreach_sep (@var{macro}, @var{pre}, @var{post}, @
+  @var{sep})
+@deffnx Composite stack_foreach_sep_lifo (@var{macro}, @var{pre}, @
+  @var{post}, @var{sep})
+For each of the @code{pushdef} definitions associated with @var{macro},
+expand the sequence @samp{@var{pre}`'definition`'@var{post}}.
+Additionally, expand @var{sep} between definitions.
+@code{stack_foreach_sep} visits the oldest definition first, while
+@code{stack_foreach_sep_lifo} visits the current definition first.  The
+expansion may dereference @var{macro}, but should not modify it.  There
+are a few special macros, such as @code{defn}, which cannot be used as
+the @var{macro} parameter.
+@end deffn
+
+Note that @code{stack_foreach(`@var{macro}', `@var{action}')} is
+equivalent to @code{stack_foreach_sep(`@var{macro}', `@var{action}(',
+`)')}.  By supplying explicit parentheses, split among the @var{pre} and
+@var{post} arguments to @code{stack_foreach_sep}, it is now possible to
+construct macro calls with more than one argument, without passing
+builtin tokens through a macro call.  It is likewise possible to
+directly reference the stack definitions without a macro call, by
+leaving @var{pre} and @var{post} empty.  Thus, in addition to fixing
+@code{copy} on builtin tokens, it also executes with fewer macro
+invocations.
+
+The new macro also adds a separator that is only output after the first
+iteration of the helper @code{_stack_reverse_sep}, implemented by
+prepending the original @var{sep} to @var{pre} and omitting a @var{sep}
+argument in subsequent iterations.  Note that the empty string that
+separates @var{sep} from @var{pre} is provided as part of the fourth
+argument when originally calling @code{_stack_reverse_sep}, and not by
+writing @code{$4`'$3} as the third argument in the recursive call; while
+the other approach would give the same output, it does so at the expense
+of increasing the argument size on each iteration of
+@code{_stack_reverse_sep}, which results in quadratic instead of linear
+execution time.  The improved stack walking macros are available in
+@file{m4-@value{VERSION}/@/examples/@/stack_sep.m4}:

+
+The replacement @code{m4wrap} versions presented above, designed to
+guarantee FIFO or LIFO order regardless of the underlying M4
+implementation, share a bug when dealing with wrapped text that looks
+like parameter expansion.  Note how the invocation of
+@code{m4wrap@var{n}} interprets these parameters, while using the
+builtin preserves them for their intended use.
+
+@comment examples

+
+Additionally, the computation of @code{_m4wrap_level} and creation of
+multiple @code{m4wrap@var{n}} placeholders in the original examples is
+more expensive in time and memory than strictly necessary.  Notice how
+the improved version grabs the wrapped text via @code{defn} to avoid
+parameter expansion, then undefines @code{_m4wrap_text}, before
+stripping a level of quotes with @code{_arg1} to expand the text.  That
+way, each level of wrapping reuses the single placeholder, which starts
+each nesting level in an undefined state.
+
+Finally, it is worth emulating the GNU M4 extension of saving
+all arguments to @code{m4wrap}, separated by a space, rather than saving
+just the first argument.  This is done with the @code{join} macro
+documented previously (@pxref{Shift}).  The improved LIFO example is

+
+The @code{capitalize} macro (@pxref{Patsubst}) as presented earlier does

+three macros @code{active}, @code{Active}, and @code{ACTIVE}, and the
+difference between calling @code{capitalize} with the expansion of a
+macro, expanding the result of a case change, and changing the case of a
+double-quoted string:
+
+@comment examples
+@example
+$ @kbd{m4 -I examples}
+include(`capitalize.m4')dnl
+define(`active', `act1, ive')dnl
+define(`Active', `Act2, Ive')dnl

+define(`A', `OOPS')
+@result{}
+capitalize(active)
+@result{}OOPSct1
+capitalize(`active')
+@result{}OOPSctive
+@end example
+
+First, when @code{capitalize} is called with more than one argument, it
+was throwing away later arguments, whereas @code{upcase} and
+@code{downcase} used @samp{$*} to collect them all.  The fix is simple:
+use @samp{$*} consistently.
+
+Next, with single-quoting, @code{capitalize} outputs a single character,
+a set of quotes, then the rest of the characters, making it impossible
+to invoke @code{Active} after the fact, and allowing the alternate macro
+@code{A} to interfere.  Here, the solution is to use additional quoting
+in the helper macros, then pass the final over-quoted output string
+through @code{_arg1} to remove the extra quoting and finally invoke the
+concatenated portions as a single string.
+
+Finally, when passed a double-quoted string, the nested macro
+@code{_capitalize} is never invoked because it ended up nested inside
+quotes.  This one is the toughest to fix.  In short, we have no idea how
+many levels of quotes are in effect on the substring being altered by
+@code{patsubst}.  If the replacement string cannot be expressed entirely
+in terms of literal text and backslash substitutions, then we need a
+mechanism to guarantee that the helper macros are invoked outside of
+quotes.  In other words, this sounds like a job for @code{changequote}
+(@pxref{Changequote}).  By changing the active quoting characters, we
+can guarantee that replacement text injected by @code{patsubst} always
+occurs in the middle of a string that has exactly one level of
+over-quoting using alternate quotes; so the replacement text closes the
+quoted string, invokes the helper macros, then reopens the quoted
+string.  In turn, that means the replacement text has unbalanced quotes,
+necessitating another round of @code{changequote}.
+
+In the fixed version below, (also shipped as
+@file{m4-@value{VERSION}/@/examples/@/capitalize2.m4}), @code{capitalize}
+uses the alternate quotes of @samp{<<} and @samp{>>} (the longer
+strings are chosen so as to be less likely to appear in the text being
+converted).  The helpers @code{_to_alt} and @code{_from_alt} merely
+reduce the number of characters required to perform a
+@code{changequote}, since the definition changes twice.  The outermost
+pair means that @code{patsubst} and @code{_capitalize_alt} are invoked
+with alternate quoting; the innermost pair is used so that the third
+argument to @code{patsubst} can contain an unbalanced
+@samp{>>}/@samp{<<} pair.  Note that @code{upcase} and @code{downcase}
+must be redefined as @code{_upcase_alt} and @code{_downcase_alt}, since
+they contain nested quotes but are invoked with the alternate quoting
+scheme in effect.

+@node Improved fatal_error
+@section Solution for @code{fatal_error}
+
+The @code{fatal_error} macro (@pxref{M4exit}) is not robust to versions
+of GNU M4 earlier than 1.4.8, where invoking
+@code{@w{__file__}} (@pxref{Location}) inside @code{m4wrap} would result
+in an empty string, and @code{@w{__line__}} resulted in @samp{0} even
+though all files start at line 1.  Furthermore, versions earlier than
+1.4.6 did not support the @code{@w{__program__}} macro.  If you want
+@code{fatal_error} to work across the entire 1.4.x release series, a
+better implementation would be:
+
+@comment status: 1
+@example
+define(`fatal_error',
+  `errprint(ifdef(`__program__', `__program__', ``m4'')'dnl
+`:ifelse(__line__, `0', `',
+    `__file__:__line__:')` fatal error: $*
+')m4exit(`1')')
+@result{}
+m4wrap(`divnum(`demo of internal message')
+fatal_error(`inside wrapped text')')
+@result{}
+^D
+@error{}m4:stdin:6: Warning: excess arguments to builtin `divnum' ignored
+@result{}0
+@error{}m4:stdin:6: fatal error: inside wrapped text

+   Why?  We need a data structure that
+
+     1) Can contain an arbitrary number of 'char *' values.  The strings
+        are compared via strcmp, not pointer comparison.
+     2) Has insertion and deletion operations that are fast: ideally O(1),
+        or possibly O(log n).  This is important for GNU sort, which may
+        create a large number of temporary files.
+     3) Allows iteration through all elements from within a signal handler.
+     4) May or may not allow duplicates.  It doesn't matter here, since
+        any file or subdir can only be removed once.
+
+   Criterion 1) would allow any gl_list_t or gl_oset_t implementation.
+
+   Criterion 2) leaves only GL_LINKEDHASH_LIST, GL_TREEHASH_LIST, or
+   GL_TREE_OSET.
+
+   Criterion 3) puts at disadvantage GL_TREEHASH_LIST and GL_TREE_OSET.
+   Namely, iteration through the elements of a binary tree requires access
+   to many ->left, ->right, ->parent pointers. However, the rebalancing
+   code for insertion and deletion in an AVL or red-black tree is so
+   complicated that we cannot assume that >left, ->right, ->parent pointers
+   are in a consistent state throughout these operations.  Therefore, to
+   avoid a crash in the signal handler, all destructive operations to the
+   lists would have to be protected by a
+       block_fatal_signals ();
+       ...
+       unblock_fatal_signals ();
+   pair.  Which causes extra system calls.
+
+   Criterion 3) would also discourage GL_ARRAY_LIST and GL_CARRAY_LIST,
+   if they were not already excluded.  Namely, these implementations use
+   xrealloc(), leaving a time window in which in the list->elements pointer
+   points to already deallocated memory.  To avoid a crash in the signal
+   handler at such a moment, all destructive operations would have to
+   protected by block/unblock_fatal_signals (), in this case too.
+
+   A list of type GL_LINKEDHASH_LIST without duplicates fulfills all
+   requirements:
+     2) Insertion and deletion are O(1) on average.
+     3) The gl_list_iterator, gl_list_iterator_next implementations do
+        not trigger memory allocations, nor other system calls, and are
+        therefore safe to be called from a signal handler.
+        Furthermore, since SIGNAL_SAFE_LIST is defined, the implementation
+        of the destructive functions ensures that the list structure is
+        safe to be traversed at any moment, even when interrupted by an
+        asynchronous signal.

+/* Temporary directories and temporary files should be automatically removed
+   when the program exits either normally or through a fatal signal.  We can't
+   rely on the "unlink before close" idiom, because it works only on Unix and
+   also - if no signal blocking is used - leaves a time window where a fatal
+   signal would not clean up the temporary file.
+
+   Also, open file descriptors need to be closed before the temporary files
+   and the temporary directories can be removed, because only on Unix
+   (excluding Cygwin) can one remove directories containing open files.
+
+   There are two modules:
+     - 'clean-temp' provides support for temporary directories and temporary
+       files inside these temporary directories,
+     - 'clean-temp-simple' provides support for temporary files without
+       temporary directories.
+   The temporary directories and files are automatically cleaned up (at the
+   latest) when the program exits or dies from a fatal signal such as SIGINT,
+   SIGTERM, SIGHUP, but not if it dies from a fatal signal such as SIGQUIT,
+   SIGKILL, or SIGABRT, SIGSEGV, SIGBUS, SIGILL, SIGFPE.
+
+   For the cleanup in the normal case, programs that use this module need to
+   call 'cleanup_temp_dir' for each successful return of 'create_temp_dir'.
+   The cleanup in the case of a fatal signal such as SIGINT, SIGTERM, SIGHUP,
+   is done entirely automatically by the functions of this module.
+
+   Limitations: Files or directories can still be left over if
+     - the program is dies from a fatal signal such as SIGQUIT, SIGKILL, or
+       SIGABRT, SIGSEGV, SIGBUS, SIGILL, SIGFPE, or
+     - in a multithreaded program, the fatal signal handler is already running
+       while another thread of the program creates a new temporary directory
+       or temporary file, or
+     - on native Windows, some temporary files are used by a subprocess while
+       the fatal signal interrupts the program.

+   Suppress extern inline with HP-UX cc, as it appears to be broken; see
+   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
+
+   Suppress extern inline with Sun C in standards-conformance mode, as it
+   mishandles inline functions that call each other.  E.g., for 'inline void f
+   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+   'reference to static identifier "f" in extern inline function'.
+   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement
+   functions or macros in standard C headers like <ctype.h>.  For example,
+   if isdigit is mistakenly implemented via a static inline function,
+   a program containing an extern inline function that calls isdigit
+   may not work since the C standard prohibits extern inline functions
+   from calling static functions (ISO C 99 section 6.7.4.(3).
+   This bug is known to occur on:
+
+     OS X 10.8 and earlier; see:
+     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+     DragonFly; see
+     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
+
+     FreeBSD; see:
+     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+   Assume DragonFly and FreeBSD will be similar.
+
+   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+   inline semantics, unless -fgnu89-inline is used.  It defines a macro
+   __GNUC_STDC_INLINE__ to indicate this situation or a macro

+/* The i386 floating point hardware (the 387 compatible FPU, not the modern
+   SSE/SSE2 hardware) has a controllable rounding precision.  It is specified
+   through the 'PC' bits in the FPU control word ('fctrl' register).  (See
+   the GNU libc i386 <fpu_control.h> header for details.)
+
+   On some platforms, such as Linux or Solaris, the default precision setting
+   is set to "extended precision".  This means that 'long double' instructions
+   operate correctly, but 'double' computations often produce slightly
+   different results as on strictly IEEE 754 conforming systems.
+
+   On some platforms, such as NetBSD, the default precision is set to
+   "double precision".  This means that 'long double' instructions will operate
+   only as 'double', i.e. lead to wrong results.  Similarly on FreeBSD 6.4, at
+   least for the division of 'long double' numbers.
+
+   The FPU control word is under control of the application, i.e. it is
+   not required to be set either way by the ABI.  (In fact, the i386 ABI
+   https://www.linux-mips.org/pub/linux/mips/doc/ABI/abi386-4.pdf page 3-12 = page 38
+   is not clear about it.  But in any case, gcc treats the control word
+   like a "preserved" register: it emits code that assumes that the control
+   word is preserved across calls, and it restores the control word at the
+   end of functions that modify it.)
+
+   See Vincent Lefèvre's page https://www.vinc17.net/research/extended.en.html
+   for a good explanation.
+   See https://web.archive.org/web/20060905133417/http://www.uwsg.iu.edu/hypermail/linux/kernel/0103.0/0453.html

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If 'getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If 'getopt' finds another option character, it returns that character,
+   updating 'optind' and 'nextchar' so that the next call to 'getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, 'getopt' returns -1.
+   Then 'optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set 'opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in 'optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in 'optarg', otherwise 'optarg' is set to zero.
+
+   If OPTSTRING starts with '-' or '+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with '--' instead of '-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a '=', or else the in next ARGV-element.
+   When 'getopt' finds a long-named option, it returns 0 if that option's
+   'flag' field is nonzero, the value of the option's 'val' field
+   if the 'flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of 'struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */

+/* gl_list is an abstract list data type.  It can contain any number of
+   objects ('void *' or 'const void *' pointers) in any given order.
+   Duplicates are allowed, but can optionally be forbidden.
+
+   There are several implementations of this list datatype, optimized for
+   different operations or for memory.  You can start using the simplest list
+   implementation, GL_ARRAY_LIST, and switch to a different implementation
+   later, when you realize which operations are performed the most frequently.
+   The API of the different implementations is exactly the same; when
+   switching to a different implementation, you only have to change the
+   gl_list_create call.
+
+   The implementations are:
+     GL_ARRAY_LIST        a growable array
+     GL_CARRAY_LIST       a growable circular array
+     GL_LINKED_LIST       a linked list
+     GL_AVLTREE_LIST      a binary tree (AVL tree)
+     GL_RBTREE_LIST       a binary tree (red-black tree)
+     GL_LINKEDHASH_LIST   a hash table with a linked list
+     GL_AVLTREEHASH_LIST  a hash table with a binary tree (AVL tree)
+     GL_RBTREEHASH_LIST   a hash table with a binary tree (red-black tree)
+
+   The memory consumption is asymptotically the same: O(1) for every object
+   in the list.  When looking more closely at the average memory consumed
+   for an object, GL_ARRAY_LIST is the most compact representation, and
+   GL_LINKEDHASH_LIST and GL_TREEHASH_LIST need more memory.
+
+   The guaranteed average performance of the operations is, for a list of
+   n elements:
+
+   Operation                  ARRAY    LINKED    TREE    LINKEDHASH   TREEHASH
+                              CARRAY                   with|without with|without

+/* gl_oset is an abstract ordered set data type.  It can contain any number
+   of objects ('void *' or 'const void *' pointers) in the order of a given
+   comparator function.  Duplicates (in the sense of the comparator) are
+   forbidden.
+
+   There are several implementations of this ordered set datatype, optimized
+   for different operations or for memory.  You can start using the simplest
+   ordered set implementation, GL_ARRAY_OSET, and switch to a different
+   implementation later, when you realize which operations are performed
+   the most frequently.  The API of the different implementations is exactly
+   the same; when switching to a different implementation, you only have to
+   change the gl_oset_create call.
+
+   The implementations are:
+     GL_ARRAY_OSET        a growable array
+     GL_AVLTREE_OSET      a binary tree (AVL tree)
+     GL_RBTREE_OSET       a binary tree (red-black tree)
+
+   The memory consumption is asymptotically the same: O(1) for every object
+   in the set.  When looking more closely at the average memory consumed
+   for an object, GL_ARRAY_OSET is the most compact representation, and
+   GL_AVLTREE_OSET, GL_RBTREE_OSET need more memory.
+
+   The guaranteed average performance of the operations is, for a set of
+   n elements:
+
+   Operation                  ARRAY     TREE
+
+   gl_oset_size                O(1)     O(1)
+   gl_oset_add                 O(n)   O(log n)
+   gl_oset_remove              O(n)   O(log n)
+   gl_oset_update              O(n)   O(log n)
+   gl_oset_search            O(log n) O(log n)
+   gl_oset_search_atleast    O(log n) O(log n)
+   gl_oset_iterator            O(1)   O(log n)
+   gl_oset_iterator_atleast  O(log n) O(log n)
+   gl_oset_iterator_next       O(1)   O(log n)

+   entry contents may be hashed by a randomization function (the hashing
+   function, or just "hasher" for short) into a number (or "slot") between 0
+   and the current table size.  At each slot position in the hash table,
+   starts a linked chain of entries for which the user data all hash to this
+   slot.  A bucket is the collection of all entries hashing to the same slot.
+
+   A good "hasher" function will distribute entries rather evenly in buckets.
+   In the ideal case, the length of each bucket is roughly the number of
+   entries divided by the table size.  Finding the slot for a data is usually
+   done in constant time by the "hasher", and the later finding of a precise
+   entry is linear in time with the size of the bucket.  Consequently, a
+   larger hash table size (that is, a larger number of buckets) is prone to
+   yielding shorter chains, *given* the "hasher" function behaves properly.
+
+   Long buckets slow down the lookup algorithm.  One might use big hash table
+   sizes in hope to reduce the average length of buckets, but this might
+   become inordinate, as unused slots in the hash table take some space.  The
+   best bet is to make sure you are using a good "hasher" function (beware

+
+/* The type 'idx_t' holds an (array) index or an (object) size.
+   Its implementation promotes to a signed integer type,
+   which can hold the values
+     0..2^63-1 (on 64-bit platforms) or
+     0..2^31-1 (on 32-bit platforms).
+
+   Why a signed integer type?
+
+     * Security: Signed types can be checked for overflow via
+       '-fsanitize=undefined', but unsigned types cannot.
+
+     * Comparisons without surprises: ISO C99 § 6.3.1.8 specifies a few
+       surprising results for comparisons, such as
+
+           (int) -3 < (unsigned long) 7  =>  false
+           (int) -3 < (unsigned int) 7   =>  false
+       and on 32-bit machines:
+           (long) -3 < (unsigned int) 7  =>  false
+
+       This is surprising because the natural comparison order is by
+       value in the realm of infinite-precision signed integers (ℤ).
+
+       The best way to get rid of such surprises is to use signed types
+       for numerical integer values, and use unsigned types only for
+       bit masks and enums.
+
+   Why not use 'size_t' directly?
+
+     * Because 'size_t' is an unsigned type, and a signed type is better.
+       See above.
+
+   Why not use 'ptrdiff_t' directly?
+
+     * Maintainability: When reading and modifying code, it helps to know that
+       a certain variable cannot have negative values.  For example, when you
+       have a loop
+
+         int n = ...;
+         for (int i = 0; i < n; i++) ...
+
+       or
+
+         ptrdiff_t n = ...;
+         for (ptrdiff_t i = 0; i < n; i++) ...
+
+       you have to ask yourself "what if n < 0?".  Whereas in
+
+         idx_t n = ...;
+         for (idx_t i = 0; i < n; i++) ...
+
+       you know that this case cannot happen.
+
+       Similarly, when a programmer writes
+
+         idx_t = ptr2 - ptr1;
+
+       there is an implied assertion that ptr1 and ptr2 point into the same
+       object and that ptr1 <= ptr2.
+
+     * Being future-proof: In the future, range types (integers which are
+       constrained to a certain range of values) may be added to C compilers
+       or to the C standard.  Several programming languages (Ada, Haskell,
+       Common Lisp, Pascal) already have range types.  Such range types may
+       help producing good code and good warnings.  The type 'idx_t' could
+       then be typedef'ed to a range type that is signed after promotion.  */
+
+/* In the future, idx_t could be typedef'ed to a signed range type.
+   The clang "extended integer types", supported in Clang 11 or newer
+   <https://clang.llvm.org/docs/LanguageExtensions.html#extended-integer-types>,
+   are a special case of range types.  However, these types don't support binary
+   operators with plain integer types (e.g. expressions such as x > 1).
+   Therefore, they don't behave like signed types (and not like unsigned types
+   either).  So, we cannot use them here.  */
+
+/* Use the signed type 'ptrdiff_t'.  */
+/* Note: ISO C does not mandate that 'size_t' and 'ptrdiff_t' have the same
+   size, but it is so on all platforms we have seen since 1990.  */

+
+   The INT_<op>_OVERFLOW macros return 1 if the corresponding C operators
+   might not yield numerically correct answers due to arithmetic overflow.
+   The INT_<op>_WRAPV macros compute the low-order bits of the sum,
+   difference, and product of two C integers, and return 1 if these
+   low-order bits are not numerically correct.
+   These macros work correctly on all known practical hosts, and do not rely
+   on undefined behavior due to signed arithmetic overflow.
+
+   Example usage, assuming A and B are long int:
+
+     if (INT_MULTIPLY_OVERFLOW (a, b))
+       printf ("result would overflow\n");
+     else
+       printf ("result is %ld (no overflow)\n", a * b);
+
+   Example usage with WRAPV flavor:
+
+     long int result;
+     bool overflow = INT_MULTIPLY_WRAPV (a, b, &result);
+     printf ("result is %ld (%s)\n", result,
+             overflow ? "after overflow" : "no overflow");
+
+   Restrictions on these macros:
+
+   These macros do not check for all possible numerical problems or
+   undefined or unspecified behavior: they do not check for division
+   by zero, for bad shift counts, or for shifting negative numbers.
+
+   These macros may evaluate their arguments zero or multiple times, so the
+   arguments should not have side effects.
+
+   The WRAPV macros are not constant expressions.  They support only
+   +, binary -, and *.
+
+   Because the WRAPV macros convert the result, they report overflow
+   in different circumstances than the OVERFLOW macros do.  For
+   example, in the typical case with 16-bit 'short' and 32-bit 'int',
+   if A, B and R are all of type 'short' then INT_ADD_OVERFLOW (A, B)
+   returns false because the addition cannot overflow after A and B
+   are converted to 'int', whereas INT_ADD_WRAPV (A, B, &R) returns
+   true or false depending on whether the sum fits into 'short'.
+
+   These macros are tuned for their last input argument being a constant.
+
+   Return 1 if the integer expressions A * B, A - B, -A, A * B, A / B,
+   A % B, and A << B would overflow, respectively.  */

+         LC_CTYPE file.
+       - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+         the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+       - The documentation says:
+           "... all code that calls BSD system routines should ensure
+            that the const *char parameters of these routines are in UTF-8
+            encoding. All BSD system functions expect their string
+            parameters to be in UTF-8 encoding and nothing else."
+         It also says
+           "An additional caveat is that string parameters for files,
+            paths, and other file-system entities must be in canonical
+            UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+            characters are decomposed ..."
+         but this is not true: You can pass non-decomposed UTF-8 strings
+         to file system functions, and it is the OS which will convert
+         them to decomposed UTF-8 before accessing the file system.
+       - The Apple Terminal application displays UTF-8 by default.
+       - However, other applications are free to use different encodings:
+         - xterm uses ISO-8859-1 by default.
+         - TextEdit uses MacRoman by default.
+       We prefer UTF-8 over decomposed UTF-8-MAC because one should
+       minimize the use of decomposed Unicode. Unfortunately, through the
+       Darwin file system, decomposed UTF-8 strings are leaked into user
+       space nevertheless.
+       Then there are also the locales with encodings other than US-ASCII
+       and UTF-8. These locales can be occasionally useful to users (e.g.
+       when grepping through ISO-8859-1 encoded text files), when all their
+       file names are in US-ASCII.

+/* Pre-processor macros which act as parameters:
+
+   DYNARRAY_STRUCT
+      The struct tag of dynamic array to be defined.
+   DYNARRAY_ELEMENT
+      The type name of the element type.  Elements are copied
+      as if by memcpy, and can change address as the dynamic
+      array grows.
+   DYNARRAY_PREFIX
+      The prefix of the functions which are defined.
+
+   The following parameters are optional:
+
+   DYNARRAY_ELEMENT_FREE
+      DYNARRAY_ELEMENT_FREE (E) is evaluated to deallocate the
+      contents of elements. E is of type  DYNARRAY_ELEMENT *.
+   DYNARRAY_ELEMENT_INIT
+      DYNARRAY_ELEMENT_INIT (E) is evaluated to initialize a new
+      element.  E is of type  DYNARRAY_ELEMENT *.
+      If DYNARRAY_ELEMENT_FREE but not DYNARRAY_ELEMENT_INIT is
+      defined, new elements are automatically zero-initialized.
+      Otherwise, new elements have undefined contents.
+   DYNARRAY_INITIAL_SIZE
+      The size of the statically allocated array (default:
+      at least 2, more elements if they fit into 128 bytes).
+      Must be a preprocessor constant.  If DYNARRAY_INITIAL_SIZE is 0,
+      there is no statically allocated array at, and all non-empty
+      arrays are heap-allocated.
+   DYNARRAY_FINAL_TYPE
+      The name of the type which holds the final array.  If not
+      defined, is PREFIX##finalize not provided.  DYNARRAY_FINAL_TYPE
+      must be a struct type, with members of type DYNARRAY_ELEMENT and
+      size_t at the start (in this order).
+
+   These macros are undefined after this header file has been
+   included.
+
+   The following types are provided (their members are private to the
+   dynarray implementation):

+/* To use the dynarray facility, you need to include
+   <malloc/dynarray-skeleton.c> and define the parameter macros
+   documented in that file.
+
+   A minimal example which provides a growing list of integers can be
+   defined like this:
+
+     struct int_array
+     {
+       // Pointer to result array followed by its length,
+       // as required by DYNARRAY_FINAL_TYPE.
+       int *array;
+       size_t length;
+     };
+
+     #define DYNARRAY_STRUCT dynarray_int
+     #define DYNARRAY_ELEMENT int
+     #define DYNARRAY_PREFIX dynarray_int_
+     #define DYNARRAY_FINAL_TYPE struct int_array
+     #include <malloc/dynarray-skeleton.c>
+
+   To create a three-element array with elements 1, 2, 3, use this
+   code:
+
+     struct dynarray_int dyn;
+     dynarray_int_init (&dyn);
+     for (int i = 1; i <= 3; ++i)
+       {
+         int *place = dynarray_int_emplace (&dyn);
+         assert (place != NULL);
+         *place = i;
+       }
+     struct int_array result;
+     bool ok = dynarray_int_finalize (&dyn, &result);
+     assert (ok);
+     assert (result.length == 3);
+     assert (result.array0 == 1);
+     assert (result.array1 == 2);
+     assert (result.array2 == 3);
+     free (result.array);
+
+   If the elements contain resources which must be freed, define
+   DYNARRAY_ELEMENT_FREE appropriately, like this:
+
+     struct str_array
+     {
+       char **array;
+       size_t length;
+     };
+
+     #define DYNARRAY_STRUCT dynarray_str
+     #define DYNARRAY_ELEMENT char *
+     #define DYNARRAY_ELEMENT_FREE(ptr) free (*ptr)
+     #define DYNARRAY_PREFIX dynarray_str_
+     #define DYNARRAY_FINAL_TYPE struct str_array
+     #include <malloc/dynarray-skeleton.c>
+
+   Compared to scratch buffers, dynamic arrays have the following
+   features:
+
+   - They have an element type, and are not just an untyped buffer of
+     bytes.
+
+   - When growing, previously stored elements are preserved.  (It is
+     expected that scratch_buffer_grow_preserve and
+     scratch_buffer_set_array_size eventually go away because all
+     current users are moved to dynamic arrays.)
+
+   - Scratch buffers have a more aggressive growth policy because
+     growing them typically means a retry of an operation (across an
+     NSS service module boundary), which is expensive.
+
+   - For the same reason, scratch buffers have a much larger initial
+     stack allocation.  */

+/* Scratch buffers with a default stack allocation and fallback to

+   The allocation functions (scratch_buffer_grow,

+/* A multibyte character is a short subsequence of a char* string,
+   representing a single wide character.
+
+   We use multibyte characters instead of wide characters because of
+   the following goals:
+   1) correct multibyte handling, i.e. operate according to the LC_CTYPE
+      locale,
+   2) ease of maintenance, i.e. the maintainer needs not know all details
+      of the ISO C 99 standard,
+   3) don't fail grossly if the input is not in the encoding set by the
+      locale, because often different encodings are in use in the same
+      countries (ISO-8859-1/UTF-8, EUC-JP/Shift_JIS, ...),
+   4) fast in the case of ASCII characters,
+   5) portability, i.e. don't make unportable assumptions about wchar_t.
+
+   Multibyte characters are only accessed through the mb* macros.
+
+   mb_ptr (mbc)
+     return a pointer to the beginning of the multibyte sequence.
+
+   mb_len (mbc)
+     returns the number of bytes occupied by the multibyte sequence.
+     Always > 0.
+
+   mb_iseq (mbc, sc)
+     returns true if mbc is the standard ASCII character sc.
+
+   mb_isnul (mbc)
+     returns true if mbc is the nul character.
+
+   mb_cmp (mbc1, mbc2)
+     returns a positive, zero, or negative value depending on whether mbc1
+     sorts after, same or before mbc2.
+
+   mb_casecmp (mbc1, mbc2)
+     returns a positive, zero, or negative value depending on whether mbc1
+     sorts after, same or before mbc2, modulo upper/lowercase conversion.
+
+   mb_equal (mbc1, mbc2)
+     returns true if mbc1 and mbc2 are equal.
+
+   mb_caseequal (mbc1, mbc2)
+     returns true if mbc1 and mbc2 are equal modulo upper/lowercase conversion.
+
+   mb_isalnum (mbc)
+     returns true if mbc is alphanumeric.
+
+   mb_isalpha (mbc)
+     returns true if mbc is alphabetic.
+
+   mb_isascii(mbc)
+     returns true if mbc is plain ASCII.
+
+   mb_isblank (mbc)
+     returns true if mbc is a blank.
+
+   mb_iscntrl (mbc)
+     returns true if mbc is a control character.
+
+   mb_isdigit (mbc)
+     returns true if mbc is a decimal digit.
+
+   mb_isgraph (mbc)
+     returns true if mbc is a graphic character.
+
+   mb_islower (mbc)
+     returns true if mbc is lowercase.
+
+   mb_isprint (mbc)
+     returns true if mbc is a printable character.
+
+   mb_ispunct (mbc)
+     returns true if mbc is a punctuation character.
+
+   mb_isspace (mbc)
+     returns true if mbc is a space character.
+
+   mb_isupper (mbc)
+     returns true if mbc is uppercase.
+
+   mb_isxdigit (mbc)
+     returns true if mbc is a hexadecimal digit.
+
+   mb_width (mbc)
+     returns the number of columns on the output device occupied by mbc.
+     Always >= 0.
+
+   mb_putc (mbc, stream)
+     outputs mbc on stream, a byte oriented FILE stream opened for output.
+
+   mb_setascii (&mbc, sc)
+     assigns the standard ASCII character sc to mbc.
+
+   mb_copy (&destmbc, &srcmbc)
+     copies srcmbc to destmbc.
+
+   Here are the function prototypes of the macros.

+
+/* The macros in this file implement forward iteration through a
+   multi-byte string.
+
+   With these macros, an iteration loop that looks like
+
+      char *iter;
+      for (iter = buf; iter < buf + buflen; iter++)
+        {
+          do_something (*iter);
+        }
+
+   becomes
+
+      mbi_iterator_t iter;
+      for (mbi_init (iter, buf, buflen); mbi_avail (iter); mbi_advance (iter))
+        {
+          do_something (mbi_cur_ptr (iter), mb_len (mbi_cur (iter)));
+        }
+
+   The benefit of these macros over plain use of mbrtowc is:
+   - Handling of invalid multibyte sequences is possible without
+     making the code more complicated, while still preserving the
+     invalid multibyte sequences.
+
+   mbi_iterator_t
+     is a type usable for variable declarations.
+
+   mbi_init (iter, startptr, length)
+     initializes the iterator, starting at startptr and crossing length bytes.
+
+   mbi_avail (iter)
+     returns true if there are more multibyte characters available before
+     the end of string is reached. In this case, mbi_cur (iter) is
+     initialized to the next multibyte character.
+
+   mbi_advance (iter)
+     advances the iterator by one multibyte character.
+
+   mbi_cur (iter)
+     returns the current multibyte character, of type mbchar_t.  All the
+     macros defined in mbchar.h can be used on it.
+
+   mbi_cur_ptr (iter)
+     return a pointer to the beginning of the current multibyte character.
+
+   mbi_reloc (iter, ptrdiff)
+     relocates iterator when the string is moved by ptrdiff bytes.
+
+   mbi_copy (&destiter, &srciter)
+     copies srciter to destiter.
+

+
+/* Written by Bruno Haible <bruno@clisp.org>.  */
+
+/* The macros in this file implement forward iteration through a
+   multi-byte string, without knowing its length a-priori.
+
+   With these macros, an iteration loop that looks like
+
+      char *iter;
+      for (iter = buf; *iter != '\0'; iter++)
+        {
+          do_something (*iter);
+        }
+
+   becomes
+
+      mbui_iterator_t iter;
+      for (mbui_init (iter, buf); mbui_avail (iter); mbui_advance (iter))
+        {
+          do_something (mbui_cur_ptr (iter), mb_len (mbui_cur (iter)));
+        }
+
+   The benefit of these macros over plain use of mbrtowc is:
+   - Handling of invalid multibyte sequences is possible without
+     making the code more complicated, while still preserving the
+     invalid multibyte sequences.
+
+   Compared to mbiter.h, the macros here don't need to know the string's
+   length a-priori.  The downside is that at each step, the look-ahead
+   that guards against overrunning the terminating '\0' is more expensive.
+   The mbui_* macros are therefore suitable when there is a high probability
+   that only the first few multibyte characters need to be inspected.
+   Whereas the mbi_* macros are better if usually the iteration runs
+   through the entire string.
+
+   mbui_iterator_t
+     is a type usable for variable declarations.
+
+   mbui_init (iter, startptr)
+     initializes the iterator, starting at startptr.
+
+   mbui_avail (iter)
+     returns true if there are more multibyte characters available before
+     the end of string is reached. In this case, mbui_cur (iter) is
+     initialized to the next multibyte character.
+
+   mbui_advance (iter)
+     advances the iterator by one multibyte character.
+
+   mbui_cur (iter)
+     returns the current multibyte character, of type mbchar_t.  All the
+     macros defined in mbchar.h can be used on it.
+
+   mbui_cur_ptr (iter)
+     return a pointer to the beginning of the current multibyte character.
+
+   mbui_reloc (iter, ptrdiff)
+     relocates iterator when the string is moved by ptrdiff bytes.
+
+   mbui_copy (&destiter, &srciter)
+     copies srciter to destiter.
+
+   Here are the function prototypes of the macros.
+
+   extern void          mbui_init (mbui_iterator_t iter, const char *startptr);
+   extern bool          mbui_avail (mbui_iterator_t iter);

+     with repeated_c.  This reduces the task to testing whether *any of the
+     four* bytes in longword1 is zero.
+
+     We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more

+     an xor with repeated_c1 and repeated_c2, respectively.  This reduces
+     the task to testing whether *any of the four* bytes in longword1 or
+     longword2 is zero.
+
+     Let's consider longword1.  We compute tmp1 =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp1 is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     Similarly, we compute tmp2 =
+       ((longword2 - repeated_one) & ~longword2) & (repeated_one << 7).
+
+     The test whether any byte in longword1 or longword2 is zero is equivalent
+     to testing whether tmp1 is nonzero or tmp2 is nonzero.  We can combine
+     this into a single test, whether (tmp1 | tmp2) is nonzero.  */

+/* Summary:
+
+   All the apparent functions defined here are macros. The idea
+   is that you would use these pre-tested macros to solve a
+   very specific set of problems, and they would run fast.
+   Caution: no side-effects in arguments please!! They may be
+   evaluated MANY times!!
+
+   These macros operate a stack of objects.  Each object starts life
+   small, and may grow to maturity.  (Consider building a word syllable
+   by syllable.)  An object can move while it is growing.  Once it has
+   been "finished" it never changes address again.  So the "top of the
+   stack" is typically an immature growing object, while the rest of the
+   stack is of mature, fixed size and fixed address objects.
+
+   These routines grab large chunks of memory, using a function you
+   supply, called 'obstack_chunk_alloc'.  On occasion, they free chunks,
+   by calling 'obstack_chunk_free'.  You must define them and declare
+   them before using any obstack macros.
+
+   Each independent stack is represented by a 'struct obstack'.
+   Each of the obstack macros expects a pointer to such a structure
+   as the first argument.
+
+   One motivation for this package is the problem of growing char strings
+   in symbol tables.  Unless you are "fascist pig with a read-only mind"
+   --Gosper's immortal quote from HAKMEM item 154, out of context--you
+   would not like to put any arbitrary upper limit on the length of your
+   symbols.
+
+   In practice this often means you will build many short symbols and a
+   few long symbols.  At the time you are reading a symbol you don't know
+   how long it is.  One traditional method is to read a symbol into a
+   buffer, realloc()ating the buffer every time you try to read a symbol
+   that is longer than the buffer.  This is beaut, but you still will
+   want to copy the symbol from the buffer to a more permanent
+   symbol-table entry say about half the time.
+
+   With obstacks, you can work differently.  Use one obstack for all symbol
+   names.  As you read a symbol, grow the name in the obstack gradually.
+   When the name is complete, finalize it.  Then, if the symbol exists already,
+   free the newly read name.
+
+   The way we do this is to take a large chunk, allocating memory from
+   low addresses.  When you want to build a symbol in the chunk you just
+   add chars above the current "high water mark" in the chunk.  When you
+   have finished adding chars, because you got to the end of the symbol,
+   you know how long the chars are, and you can create a new object.
+   Mostly the chars will not burst over the highest address of the chunk,
+   because you would typically expect a chunk to be (say) 100 times as
+   long as an average object.
+
+   In case that isn't clear, when we have enough chars to make up
+   the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+   so we just point to it where it lies.  No moving of chars is
+   needed and this is the second win: potentially long strings need
+   never be explicitly shuffled. Once an object is formed, it does not
+   change its address during its lifetime.
+
+   When the chars burst over a chunk boundary, we allocate a larger
+   chunk, and then copy the partly formed object from the end of the old
+   chunk to the beginning of the new larger chunk.  We then carry on
+   accreting characters to the end of the object as we normally would.
+
+   A special macro is provided to add a single char at a time to a
+   growing object.  This allows the use of register variables, which
+   break the ordinary 'growth' macro.
+
+   Summary:
+        We allocate large chunks.
+        We carve out one object at a time from the current chunk.
+        Once carved, an object never moves.
+        We are free to append data of any size to the currently
+          growing object.
+        Exactly one object is growing in an obstack at any one time.
+        You can run one obstack per control block.
+        You may have as many control blocks as you dare.
+        Because of the way we do it, you can "unwind" an obstack
+          back to a previous state. (You may remove objects much
+          as you would with a stack.)

+/* INTRODUCTION
+
+   What do
+
+      Torbjörn Granlund    (coreutils)
+      François Pinard      (coreutils)
+      Danilo Šegan         (gettext)
+
+   have in common?
+
+   A non-ASCII name. This causes trouble in the --version output. The simple
+   "solution" unfortunately mutilates the name.
+
+     $ du --version | grep Granlund
+     Écrit par Torbjorn Granlund, David MacKenzie, Paul Eggert et Jim Meyering.
+
+     $ ptx --version | grep Pinard
+     Écrit par F. Pinard.
+
+   What is desirable, is to print the full name if the output character set
+   allows it, and the ASCIIfied name only as a fallback.
+
+     $ recode-sr-latin --version
+     ...
+     Written by Danilo Šegan and Bruno Haible.
+
+     $ LC_ALL=C recode-sr-latin --version
+     ...
+     Written by Danilo Segan and Bruno Haible.
+
+   The 'propername' module does exactly this. Plus, for languages that use
+   a different writing system than the Latin alphabet, it allows a translator
+   to write the name using that different writing system. In that case the
+   output will look like this:
+      <translated name> (<original name in English>)
+
+   To use the 'propername' module requires three simple steps:
+
+     1) Add it to the list of gnulib modules to import,
+
+     2) Change the arguments of version_etc(),
+
+          from "Paul Eggert"
+          to   proper_name ("Paul Eggert")
+
+          from "Torbjorn Granlund"
+          to   proper_name_utf8 ("Torbjorn Granlund", "Torbj\303\266rn Granlund")
+
+          from "F. Pinard"
+          to   proper_name_utf8 ("Franc,ois Pinard", "Fran\303\247ois Pinard")
+
+        (Optionally, here you can also add / * TRANSLATORS: ... * / comments
+        explaining how the name is written or pronounced.)
+
+     3) If you are using GNU gettext version 0.16.1 or older, in po/Makevars,
+        in the definition of the XGETTEXT_OPTIONS variable, add:
+
+           --keyword='proper_name:1,"This is a proper name. See the gettext manual, section Names."'
+           --keyword='proper_name_utf8:1,"This is a proper name. See the gettext manual, section Names."'
+
+        This specifies automatic comments for the translator. (Requires
+        xgettext >= 0.15. The double-quotes inside the quoted string are on
+        purpose: they are part of the --keyword argument syntax.)

+     the four* bytes in the longword in question are equal to NUL or
+     c.  We first use an xor with repeated_c.  This reduces the task
+     to testing whether *any of the four* bytes in longword1 is zero.
+
+     We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     The test whether any byte in longword1 is zero is equivalent
+     to testing whether tmp is nonzero.
+
+     This test can read beyond the end of a string, depending on where
+     C_IN is encountered.  However, this is considered safe since the
+     initialization phase ensured that the read will be aligned,
+     therefore, the read will not cross page boundaries and will not
+     cause a fault.  */

+   The former two functions operate on STRING with length LENGTH,

+
+   re_match() matches the compiled pattern in BUFP against the string,

+
+   re_search() first tries matching at index START, then it tries to match

+   the first STOP characters of the concatenation of the strings should be
+   concerned.
+
+   If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+   and all groups is stored in REGS.  (For the "_2" variants, the offsets are
+   computed relative to the concatenation, not relative to the individual
+   strings.)

+   signal() has SysV semantics (ie. the handler is uninstalled before
+   it is invoked).  This is an inherent data race if an asynchronous
+   signal is sent twice in a row before we can reinstall our handler,
+   but there's nothing we can do about it.  Meanwhile, sigprocmask()
+   is not present, and while we can use the gnulib replacement to
+   provide critical sections, it too suffers from potential data races
+   in the face of an ill-timed asynchronous signal.  And we compound
+   the situation by reading static storage in a signal handler, which
+   POSIX warns is not generically async-signal-safe.  Oh well.
+
+   Additionally:
+     - We don't implement SA_NOCLDSTOP or SA_NOCLDWAIT, because SIGCHLD
+       is not defined.
+     - We don't implement SA_ONSTACK, because sigaltstack() is not present.
+     - We ignore SA_RESTART, because blocking native Windows API calls are
+       not interrupted anyway when an asynchronous signal occurs, and the
+       MSVCRT runtime never sets errno to EINTR.
+     - We don't implement SA_SIGINFO because it is impossible to do so
+       portably.
+
+   POSIX states that an application should not mix signal() and
+   sigaction().  We support the use of signal() within the gnulib
+   sigprocmask() substitute, but all other application code linked
+   with this module should stick with only sigaction().  */

+
+   HAVE_STACK_OVERFLOW_RECOVERY
+       if HAVE_SIGALTSTACK is set and
+       at least two of the following are true:
+       A) There is a fault-*.h include file which defines
+          SIGSEGV_FAULT_HANDLER_ARGLIST and SIGSEGV_FAULT_ADDRESS.
+       B) There is a fault-*.h include file which defines
+          SIGSEGV_FAULT_HANDLER_ARGLIST and SIGSEGV_FAULT_STACKPOINTER.
+       C) There is a stackvma-*.c, other than stackvma-none.c, which
+          defines sigsegv_get_vma.
+
+   Why? Obviously, to catch stack overflow, we need an alternate signal
+   stack; this requires kernel support. But we also need to distinguish
+   (with a reasonable confidence) a stack overflow from a regular SIGSEGV.
+   If we have A) and B), we use the
+     Heuristic AB: If the fault address is near the stack pointer, it's a
+     stack overflow.
+   If we have A) and C), we use the
+     Heuristic AC: If the fault address is near and beyond the bottom of
+     the stack's virtual memory area, it's a stack overflow.
+   If we have B) and C), we use the
+     Heuristic BC: If the stack pointer is near the bottom of the stack's
+     virtual memory area, it's a stack overflow.
+     This heuristic comes in two flavours: On OSes which let the stack's
+     VMA grow continuously, we determine the bottom by use of getrlimit().
+     On OSes which preallocate the stack's VMA with its maximum size
+     (like BeOS), we use the stack's VMA directly.

+/* All these functions create a subprocess and don't wait for its termination.
+   They return the process id of the subprocess.  They also return in fd
+   one or two file descriptors for communication with the subprocess.
+   If the subprocess creation fails: if exit_on_error is true, the main
+   process exits with an error message; otherwise, an error message is given
+   if null_stderr is false, then -1 is returned, with errno set, and fd
+   remain uninitialized.
+
+   After finishing communication, the caller should call wait_subprocess()
+   to get rid of the subprocess in the process table.
+
+   progname is the name of the program to be executed by the subprocess, used
+   for error messages.
+   prog_path is the file name of the program to be executed by the subprocess.
+   If it contains no slashes, a search is conducted in $PATH.  An operating
+   system dependent suffix is added, if necessary.
+   prog_argv is the array of strings that the subprocess shall receive in
+   argv.  It is a NULL-terminated array.  prog_argv0 should normally be
+   identical to prog_path.
+
+   If directory is not NULL, the subprocess is started in that directory.  If
+   prog_path is a relative file name, it resolved before changing to that
+   directory.  The current directory of the current process remains unchanged.
+
+   If slave_process is true, the child process will be terminated when its
+   creator receives a catchable fatal signal or exits normally.  If
+   slave_process is false, the child process will continue running in this
+   case, until it is lucky enough to attempt to communicate with its creator
+   and thus get a SIGPIPE signal.
+
+   If exit_on_error is false, a child process id of -1 should be treated the
+   same way as a subprocess which accepts no input, produces no output and
+   terminates with exit code 127.  Why?  Some errors during posix_spawnp()
+   cause the function posix_spawnp() to return an error code; some other
+   errors cause the subprocess to exit with return code 127.  It is
+   implementation dependent which error is reported which way.  The caller
+   must treat both cases as equivalent.
+
+   It is recommended that no signal is blocked or ignored (i.e. have a
+   signal handler with value SIG_IGN) while any of these functions is called.
+   The reason is that child processes inherit the mask of blocked signals
+   from their parent (both through posix_spawn() and fork()/exec());
+   likewise, signals ignored in the parent are also ignored in the child
+   (except possibly for SIGCHLD).  And POSIX:2001 says in the description
+   of exec():
+       "it should be noted that many existing applications wrongly
+        assume that they start with certain signals set to the default
+        action and/or unblocked. In particular, applications written
+        with a simpler signal model that does not include blocking of
+        signals, such as the one in the ISO C standard, may not behave
+        properly if invoked with some signals blocked. Therefore, it is
+        best not to block or ignore signals across execs without explicit
+        reason to do so, and especially not to block signals across execs
+        of arbitrary (not closely co-operating) programs."  */

+           - vm_region_64. It has arguments that depend on whether the current
+             process is 32-bit or 64-bit. It interprets a flavor
+             VM_REGION_BASIC_INFO as VM_REGION_BASIC_INFO_64, which is

+             VM_REGION_BASIC_INFO_64 explicitly.
+           - mach_vm_region. It has arguments that are 64-bit always. This
+             function is useful when you want to access the VM of a process
+             other than the current process.
+         In 64-bit processes, we could use vm_region_64 or mach_vm_region.

+
+   Programs that use <stdbool.h> should be aware of some limitations
+   and standards compliance issues.
+
+   Standards compliance:
+
+       - <stdbool.h> must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+       - C99 allows the use of (_Bool)0.0 in constant expressions, but
+         this substitute cannot always provide this property.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';

+/* Set up the following warnings, based on which modules are in use.
+   GNU Coding Standards discourage the use of fseek, since it imposes
+   an arbitrary limitation on some 32-bit hosts.  Remember that the
+   fseek module depends on the fseeko module, so we only have three
+   cases to consider:
+
+   1. The developer is not using either module.  Issue a warning under
+   GNULIB_POSIXCHECK for both functions, to remind them that both
+   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
+   impact on this warning.
+
+   2. The developer is using both modules.  They may be unaware of the
+   arbitrary limitations of fseek, so issue a warning under
+   GNULIB_POSIXCHECK.  On the other hand, they may be using both
+   modules intentionally, so the developer can define
+   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+   is safe, to silence the warning.
+
+   3. The developer is using the fseeko module, but not fseek.  Gnulib
+   guarantees that fseek will still work around platform bugs in that
+   case, but we presume that the developer is aware of the pitfalls of
+   fseek and was trying to avoid it, so issue a warning even when
+   GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
+   defined to silence the warning in particular compilation units.
+   In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
+   fseek gets defined as a macro, it is recommended that the developer
+   uses the fseek module, even if he is not calling the fseek function.
+
+   Most gnulib clients that perform stream operations should fall into

+
+   The global period of a string is the smallest index (possibly its
+   length) at which all remaining bytes in the string are repetitions
+   of the prefix (the last repetition may be a subset of the prefix).
+
+   When NEEDLE is factored into two halves, a local period is the

+   and shares a prefix with the right half.  All factorizations of a
+   non-empty NEEDLE have a local period of at least 1 and no greater
+   than NEEDLE_LEN.
+
+   A critical factorization has the property that the local period
+   equals the global period.  All strings have at least one critical
+   factorization with the left half smaller than the global period.
+   And while some strings have more than one critical factorization,
+   it is provable that with an ordered alphabet, at least one of the
+   critical factorizations corresponds to a maximal suffix.
+
+   Given an ordered alphabet, a critical factorization can be computed
+   in linear time, with 2 * NEEDLE_LEN comparisons, by computing the
+   shorter of two ordered maximal suffixes.  The ordered maximal
+   suffixes are determined by lexicographic comparison while tracking

+     test a longword at a time.  The tricky part is testing if *any of
+     the four* bytes in the longword in question are equal to NUL or
+     c.  We first use an xor with repeated_c.  This reduces the task
+     to testing whether *any of the four* bytes in longword1 or
+     longword2 is zero.
+
+     Let's consider longword1.  We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     The test whether any byte in longword1 or longword2 is zero is equivalent
+     to testing whether tmp1 is nonzero or tmp2 is nonzero.  We can combine
+     this into a single test, whether (tmp1 | tmp2) is nonzero.
+
+     This test can read more than one byte beyond the end of a string,
+     depending on where the terminating NUL is encountered.  However,
+     this is considered safe since the initialization phase ensured
+     that the read will be aligned, therefore, the read will not cross
+     page boundaries and will not cause a fault.  */

+
+   All functions prefixed with u8_ operate on UTF-8 encoded strings.
+   Their unit is an uint8_t (1 byte).
+
+   All functions prefixed with u16_ operate on UTF-16 encoded strings.
+   Their unit is an uint16_t (a 2-byte word).
+
+   All functions prefixed with u32_ operate on UCS-4 encoded strings.
+   Their unit is an uint32_t (a 4-byte word).
+
+   All argument pairs (s, n) denote a Unicode string s0..n-1 with exactly
+   n units.
+
+   All arguments starting with "str" and the arguments of functions starting
+   with u8_str/u16_str/u32_str denote a NUL terminated string, i.e. a string
+   which terminates at the first NUL unit.  This termination unit is
+   considered part of the string for all memory allocation purposes, but
+   is not considered part of the string for all other logical purposes.
+
+   Functions returning a string result take a (resultbuf, lengthp) argument
+   pair.  If resultbuf is not NULL and the result fits into *lengthp units,
+   it is put in resultbuf, and resultbuf is returned.  Otherwise, a freshly
+   allocated string is returned.  In both cases, *lengthp is set to the
+   length (number of units) of the returned string.  In case of error,

+                       <https://android.googlesource.com/platform/bionic/+/41398d03b7e8e0dfb951660ae713e682e9fc0336>).
+                   On these platforms, HAVE_SNPRINTF_RETVAL_C99 and
+                   HAVE_SNPRINTF_TRUNCATION_C99 are 1. We have listed them
+                   explicitly in the condition above, in case of cross-
+                   compilation (just to be sure).  */
+                /* On native Windows systems (such as mingw), we can avoid using
+                   %n because:
+                     - Although the gl_SNPRINTF_TRUNCATION_C99 test fails,
+                       snprintf does not write more than the specified number
+                       of bytes. (snprintf (buf, 3, "%d %d", 4567, 89) writes
+                       '4', '5', '6' into buf, not '4', '5', '\0'.)
+                     - Although the gl_SNPRINTF_RETVAL_C99 test fails, snprintf
+                       allows us to recognize the case of an insufficient
+                       buffer size: it returns -1 in this case.
+                   On native Windows systems (such as mingw) where the OS is
+                   Windows Vista, the use of %n in format strings by default
+                   crashes the program. See

+/* Each of these macros verifies that its argument R is nonzero.  To
+   be portable, R should be an integer constant expression.  Unlike
+   assert (R), there is no run-time overhead.
+
+   If _Static_assert works, verify (R) uses it directly.  Similarly,
+   _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
+   that is an operand of sizeof.
+
+   The code below uses several ideas for C++ compilers, and for C
+   compilers that do not support _Static_assert:
+
+   * The first step is ((R) ? 1 : -1).  Given an expression R, of
+     integral or boolean or floating-point type, this yields an
+     expression of integral type, whose value is later verified to be
+     constant and nonnegative.
+
+   * Next this expression W is wrapped in a type
+     struct _gl_verify_type {
+       unsigned int _gl_verify_error_if_negative: W;
+     }.
+     If W is negative, this yields a compile-time error.  No compiler can
+     deal with a bit-field of negative size.
+
+     One might think that an array size check would have the same
+     effect, that is, that the type struct { unsigned int dummyW; }
+     would work as well.  However, inside a function, some compilers
+     (such as C++ compilers and GNU C) allow local parameters and
+     variables inside array size expressions.  With these compilers,
+     an array size check would not properly diagnose this misuse of
+     the verify macro:
+
+       void function (int n) { verify (n < 0); }
+
+   * For the verify macro, the struct _gl_verify_type will need to
+     somehow be embedded into a declaration.  To be portable, this
+     declaration must declare an object, a constant, a function, or a
+     typedef name.  If the declared entity uses the type directly,
+     such as in
+
+       struct dummy {...};
+       typedef struct {...} dummy;
+       extern struct {...} *dummy;
+       extern void dummy (struct {...} *);
+       extern struct {...} *dummy (void);
+
+     two uses of the verify macro would yield colliding declarations
+     if the entity names are not disambiguated.  A workaround is to
+     attach the current line number to the entity name:
+
+       #define _GL_CONCAT0(x, y) x##y
+       #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
+       extern struct {...} * _GL_CONCAT (dummy, __LINE__);
+
+     But this has the problem that two invocations of verify from
+     within the same macro would collide, since the __LINE__ value
+     would be the same for both invocations.  (The GCC __COUNTER__
+     macro solves this problem, but is not portable.)
+
+     A solution is to use the sizeof operator.  It yields a number,
+     getting rid of the identity of the type.  Declarations like
+
+       extern int dummy sizeof (struct {...});
+       extern void dummy (int sizeof (struct {...}));
+       extern int (*dummy (void)) sizeof (struct {...});
+
+     can be repeated.
+
+   * Should the implementation use a named struct or an unnamed struct?
+     Which of the following alternatives can be used?
+
+       extern int dummy sizeof (struct {...});
+       extern int dummy sizeof (struct _gl_verify_type {...});
+       extern void dummy (int sizeof (struct {...}));
+       extern void dummy (int sizeof (struct _gl_verify_type {...}));
+       extern int (*dummy (void)) sizeof (struct {...});
+       extern int (*dummy (void)) sizeof (struct _gl_verify_type {...});
+
+     In the second and sixth case, the struct type is exported to the
+     outer scope; two such declarations therefore collide.  GCC warns
+     about the first, third, and fourth cases.  So the only remaining
+     possibility is the fifth case:
+
+       extern int (*dummy (void)) sizeof (struct {...});
+
+   * GCC warns about duplicate declarations of the dummy function if
+     -Wredundant-decls is used.  GCC 4.3 and later have a builtin
+     __COUNTER__ macro that can let us generate unique identifiers for
+     each dummy function, to suppress this warning.
+
+   * This implementation exploits the fact that older versions of GCC,
+     which do not support _Static_assert, also do not warn about the
+     last declaration mentioned above.
+
+   * GCC warns if -Wnested-externs is enabled and 'verify' is used
+     within a function body; but inside a function, you can always
+     arrange to use verify_expr instead.
+
+   * In C++, any struct definition inside sizeof is invalid.
+     Use a template type to work around the problem.  */

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
+   this feature, it expands to empty.
+
+   These macros are useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.
+   _GL_WARN_ON_USE is for functions with 'extern' linkage.
+   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+   linkage.
+
+   However, one of the reasons that a function is a portability trap is
+   if it has the wrong signature.  Declaring FUNCTION with a different
+   signature in C is a compilation error, so this macro must use the
+   same type as any existing declaration so that programs that avoid
+   the problematic FUNCTION do not fail to compile merely because they
+   included a header that poisoned the function.  But this implies that
+   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+   have a declaration.  Use of this macro implies that there must not
+   be any other macro hiding the declaration of FUNCTION; but
+   undefining FUNCTION first is part of the poisoning process anyway
+   (although for symbols that are provided only via a macro, the result
+   is a compilation error rather than a warning containing
+   "literal string").  Also note that in C++, it is only safe to use if
+   FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+   - adding a call to gl_WARN_ON_USE_PREPARE(#include <stdio.h>,
+     getline) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     rpl_environ (void) { return &environ; }
+     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+     # undef environ
+     # define environ (*rpl_environ ())
+     #endif
+   or better (avoiding contradictory use of 'static' and 'extern'):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
+     rpl_environ (void) { return &environ; }

+   - Space and tab are interpreted as delimiters. They are not treated as
+     delimiters if they are surrounded by double quotes: "...".
+   - Unescaped double quotes are removed from the input. Their only effect is
+     that within double quotes, space and tab are treated like normal
+     characters.
+   - Backslashes not followed by double quotes are not special.
+   - But 2*n+1 backslashes followed by a double quote become
+     n backslashes followed by a double quote (n >= 0):
+       \" -> "
+       \\\" -> \"
+       \\\\\" -> \\"

+
+   Repeated reallocations are guaranteed to make progress, either by

+
+   This causes x2nrealloc to allocate a block of some nonzero size the
+   first time it is called.
+
+   To have finer-grained control over the initial size, set *PN to a
+   nonzero value before calling this function with P == NULL.  For
+   example:
+
+     int *p = NULL;
+     size_t used = 0;
+     size_t allocated = 0;
+     size_t allocated1 = 1000;

+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT(INTLSYMBOL, NEEDSYMBOL, INTLDIR).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+
+dnl From Bruno Haible and Sam Steingold.
+
+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl   will not run on SPARC CPUs and vice versa. They have different
+dnl   instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl   mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl   different argument passing and return conventions for C functions, and
+dnl   although the instruction set of 'mips' is a large subset of the
+dnl   instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl   different sizes for the C types like 'int' and 'void *', and although
+dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl   determine the endianness through preprocessor symbols:
+dnl   - 'arm': test __ARMEL__.
+dnl   - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl   - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl     assembly language source files use such instructions, you will
+dnl     need to make the distinction.
+dnl   - Speed of execution of the common instruction set is reasonable across
+dnl     the entire family of CPUs. If you have assembly language source files
+dnl     that are optimized for particular CPU types (like GNU gmp has), you
+dnl     will need to make the distinction.

+dnl From Paul Eggert and Derek Price.
+
+dnl Sets INCLUDE_NEXT, INCLUDE_NEXT_AS_FIRST_DIRECTIVE, PRAGMA_SYSTEM_HEADER,
+dnl and PRAGMA_COLUMNS.
+dnl
+dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
+dnl 'include' otherwise.
+dnl
+dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
+dnl supports it in the special case that it is the first include directive in
+dnl the given file, or to 'include' otherwise.
+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as
+dnl opposed to the search path specified with '-I' options). Namely, gcc
+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
+dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
+dnl of plain '__STDC__'.
+dnl
+dnl PRAGMA_COLUMNS can be used in files that override system header files, so
+dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
+dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
+dnl has the effect of truncating the lines of that file and all files that it
+dnl includes to 80 columns) and the gnulib file has lines longer than 80
+dnl columns.

+dnl From Bruno Haible.
+dnl Inspired by
+dnl https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_rwlock_rdlock/2-2.c
+dnl by Intel Corporation.
+
+dnl Test whether in a situation where
+dnl   - an rwlock is taken by a reader and has a writer waiting,
+dnl   - an additional reader requests the lock,
+dnl   - the waiting writer and the requesting reader threads have the same
+dnl     priority,
+dnl the requesting reader thread gets blocked, so that at some point the
+dnl waiting writer can acquire the lock.
+dnl Without such a guarantee, when there a N readers and each of the readers
+dnl spends more than 1/Nth of the time with the lock held, there is a high
+dnl probability that the waiting writer will not get the lock in a given finite
+dnl time, a phenomenon called "writer starvation".
+dnl Without such a guarantee, applications have a hard time avoiding writer
+dnl starvation.
+dnl
+dnl POSIX:2017 makes this requirement only for implementations that support TPS
+dnl (Thread Priority Scheduling) and only for the scheduling policies SCHED_FIFO
+dnl and SCHED_RR, see
+dnl https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_rdlock.html
+dnl but this test verifies the guarantee regardless of TPS and regardless of
+dnl scheduling policy.
+dnl Glibc does not provide this guarantee (and never will on Linux), see

+AC_PREREQ(2.60)
+
+dnl The general structure of the multithreading modules in gnulib is that we

+dnl
+dnl   * POSIX API:
+dnl     pthread, which combines
+dnl       pthread-h

+dnl       pthread-tss
+dnl       pthread-spin
+dnl     sched_yield
+dnl
+dnl   * ISO C API:
+dnl     threads, which combines
+dnl       threads-h
+dnl       thrd
+dnl       mtx
+dnl       cnd
+dnl       tss
+dnl
+dnl   * Gnulib API, with an implementation that can be chosen at configure
+dnl     time through the option --enable-threads=...
+dnl       thread
+dnl       lock
+dnl       cond
+dnl       tls
+dnl       yield
+dnl
+dnl They are independent, except for the fact that
+dnl   - the implementation of the ISO C API may use the POSIX (or some other
+dnl     platform dependent) API,
+dnl   - the implementation of the Gnulib API may use the POSIX or ISO C or

+dnl ------------
+dnl Tests for a multithreading library to be used.
+dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO
+dnl (it must be placed before the invocation of gl_THREADLIB_EARLY!), then the
+dnl default is 'no', otherwise it is system dependent. In both cases, the user
+dnl can change the choice through the options --enable-threads=choice or
+dnl --disable-threads.
+dnl Defines at most one of the macros USE_ISOC_THREADS, USE_POSIX_THREADS,
+dnl USE_ISOC_AND_POSIX_THREADS, USE_WINDOWS_THREADS.
+dnl The choice --enable-threads=isoc+posix is available only on platforms that
+dnl have both the ISO C and the POSIX threads APIs. It has the effect of using
+dnl the ISO C API for most things and the POSIX API only for creating and
+dnl controlling threads (because there is no equivalent to pthread_atfork in
+dnl the ISO C API).
+dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
+dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
+dnl libtool).
+dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
+dnl programs that really need multithread functionality. The difference
+dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
+dnl symbols, typically LIBTHREAD is empty whereas LIBMULTITHREAD is not.
+dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
+dnl multithread-safe programs.
+dnl Since support for GNU pth was removed, $LTLIBTHREAD and $LIBTHREAD have the
+dnl same value, and similarly $LTLIBMULTITHREAD and $LIBMULTITHREAD have the
+dnl same value. Only system libraries are needed.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the

+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. The message catalog should translate "`" to a left

+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.

+#. If the catalog has no translation, we will try to

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to

+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the

+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations

+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'".  For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK).  If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this".  You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <https://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>

+
+/* Unread input can be either files, that should be read (eg. included
+   files), strings, which should be rescanned (eg. macro expansion text),
+   or quoted macro definitions (as returned by the builtin "defn").
+   Unread input are organised in a stack, implemented with an obstack.
+   Each input source is described by a "struct input_block".  The obstack
+   is "current_input".  The top of the input stack is "isp".
+
+   The macro "m4wrap" places the text to be saved on another input
+   stack, on the obstack "wrapup_stack", whose top is "wsp".  When EOF
+   is seen on normal input (eg, when "current_input" is empty), input is
+   switched over to "wrapup_stack", and the original "current_input" is
+   freed.  A new stack is allocated for "wrapup_stack", which will
+   accept any text produced by calls to "m4wrap" from within the
+   wrapped text.  This process of shuffling "wrapup_stack" to
+   "current_input" can continue indefinitely, even generating infinite
+   loops (e.g. "define(`f',`m4wrap(`f')')f"), without memory leaks.
+
+   Pushing new input on the input stack is done by push_file (),
+   push_string (), push_wrapup () (for wrapup text), and push_macro ()
+   (for macro definitions).  Because macro expansion needs direct access
+   to the current input obstack (for optimisation), push_string () are
+   split in two functions, push_string_init (), which returns a pointer
+   to the current input stack, and push_string_finish (), which return a
+   pointer to the final text.  The input_block *next is used to manage
+   the coordination between the different push routines.
+
+   The current file and line number are stored in two global
+   variables, for use by the error handling functions in m4.c.  Macro
+   expansion wants to report the line where a macro name was detected,
+   rather than where it finished collecting arguments.  This also
+   applies to text resulting from macro expansions.  So each input
+   block maintains its own notion of the current file and line, and
+   swapping between input blocks updates the global variables
+   accordingly.  */

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

+# Using this file in a test
+# =========================
+#
+# The typical skeleton of a test looks like this:
+#
+#   #!/bin/sh
+#   . "${srcdir=.}/init.sh"; path_prepend_ .
+#   Execute some commands.
+#   Note that these commands are executed in a subdirectory, therefore you
+#   need to prepend "../" to relative filenames in the build directory.
+#   Note that the "path_prepend_ ." is useful only if the body of your
+#   test invokes programs residing in the initial directory.
+#   For example, if the programs you want to test are in src/, and this test
+#   script is named tests/test-1, then you would use "path_prepend_ ../src",
+#   or perhaps export PATH='$(abs_top_builddir)/src$(PATH_SEPARATOR)'"$$PATH"
+#   to all tests via automake's TESTS_ENVIRONMENT.
+#   Set the exit code 0 for success, 77 for skipped, or 1 or other for failure.
+#   Use the skip_ and fail_ functions to print a diagnostic and then exit
+#   with the corresponding exit code.
+#   Exit $?
+
+# Executing a test that uses this file
+# ====================================
+#
+# Running a single test:
+#   $ make check TESTS=test-foo.sh
+#
+# Running a single test, with verbose output:
+#   $ make check TESTS=test-foo.sh VERBOSE=yes
+#
+# Running a single test, keeping the temporary directory:
+#   $ make check TESTS=test-foo.sh KEEP=yes
+#
+# Running a single test, with single-stepping:
+#   1. Go into a sub-shell:
+#   $ bash
+#   2. Set relevant environment variables from TESTS_ENVIRONMENT in the
+#      Makefile:
+#   $ export srcdir=../../tests # this is an example
+#   3. Execute the commands from the test, copy&pasting them one by one:
+#   $ . "$srcdir/init.sh"; path_prepend_ .
+#   ...
+#   4. Finally
+#   $ exit

+         mach_vm_address_t and mach_vm_size_t are always 64 bits large.
+         Mac OS X 10.5 has three vm_region like methods:
+           - vm_region. It has arguments that depend on whether the current
+             process is 32-bit or 64-bit. When linking dynamically, this
+             function exists only in 32-bit processes. Therefore we use it only
+             in 32-bit processes.
+           - vm_region_64. It has arguments that depend on whether the current
+             process is 32-bit or 64-bit. It interprets a flavor
+             VM_REGION_BASIC_INFO as VM_REGION_BASIC_INFO_64, which is
+             dangerous since 'struct vm_region_basic_info_64' is larger than
+             'struct vm_region_basic_info'; therefore let's write
+             VM_REGION_BASIC_INFO_64 explicitly.
+           - mach_vm_region. It has arguments that are 64-bit always. This
+             function is useful when you want to access the VM of a process
+             other than the current process.
+         In 64-bit processes, we could use vm_region_64 or mach_vm_region.
+         I choose vm_region_64 because it uses the same types as vm_region,
+         resulting in less conditional code.  */
