+                    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;

+This file contains generic instructions on how to build and
+install software using autoconf. For specific instructions
+on how to build "less", see the README or README.VER file.
+
+
+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   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, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   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 at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.ac' is used to create `configure' by a program
+called `autoconf'.  You only 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.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  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.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. 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.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+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 must use a version of `make' that
+supports the `VPATH' variable, such as 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 `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have 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.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' 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.
+
+   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'.
+
+Optional Features
+=================
+
+   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.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+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 host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+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.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+
+    Please report any problems at https://github.com/gwsw/less/issues.
+    See https://greenwoodsoftware.com/less for the latest info.
+    Source repository is at https://github.com/gwsw/less.git.
+
+=========================================================================
+
+You should build from a clone of a git repository 
+ONLY IF you are doing development on the less source itself.
+If you are merely using less as a tool, you should download a release
+from https://greenwoodsoftware.com and NOT from github.
+
+The formatted manual page is in less.man.
+The manual page nroff source is in less.nro.
+Major changes made since the last posted version are in NEWS.
+
+=======================================================================
+INSTALLATION (Unix & Linux systems only):
+
+1. Move the distributed source to its own directory and unpack it,
+   if you have not already done so.  
+
+2. If you are building from a clone of a git repository,
+   type "make -f Makefile.aut distfiles".
+   If you are building from a numbered release package (a tar or 
+   zip file with a name like less-999.tar.gz or less-999.zip downloaded 
+   from greenwoodsoftware.com, not from github), you should skip this step. 
+
+3. Type "sh configure".
+   This will generate a Makefile and a defines.h.
+   Warning: if you have a GNU sed, make sure it is version 2.05 or later.
+
+   The file INSTALL describes the usage of the configure program in
+   general.  In addition, these options to configure are supported:
+
+   --with-editor=program
+     Specifies the default editor program used by the "v" command.
+     The default is "vi".
+
+   --with-regex=lib
+     Specifies the regular expression library used by less for pattern
+     matching.  The default is "auto", which means the configure program 
+     finds a regular expression library automatically.  Other values are:
+        gnu            Use the GNU regex library.
+        pcre           Use the PCRE library.
+        pcre2          Use the PCRE2 library.
+        posix          Use the POSIX-compatible regcomp.
+        regcmp         Use the regcmp library.
+        re_comp        Use the re_comp library.
+        regcomp        Use the V8-compatible regcomp.
+        regcomp-local  Use Henry Spencer's V8-compatible regcomp
+                       (source is supplied with less).
+        none           No regular expressions, only simple string matching.
+
+   --with-secure
+     Builds a "secure" version of less, with some features disabled
+     to prevent users from viewing other files, accessing shell
+     commands, etc.
+
+
+4. It is a good idea to look over the generated Makefile and defines.h
+   and make sure they look ok.  If you know of any peculiarities of
+   your system that configure might not have detected, you may fix the
+   Makefile now.  Take particular notice of the list of "terminal" 
+   libraries in the LIBS definition in the Makefile; these may need 
+   to be edited.  The terminal libraries will be some subset of
+       -lncurses  -lcurses  -ltermcap  -ltermlib
+
+   If you wish, you may edit defines.h to remove some optional features.
+   If you choose not to include some features in your version, you may
+   wish to edit the manual page "less.nro" and the help page "less.hlp" 
+   to remove the descriptions of the features which you are removing.
+   If you edit less.hlp, you should run "make -f Makefile.aut help.c".
+
+5. Type "make" and watch the fun.
+
+6. If the make succeeds, it will generate the programs "less",
+   "lesskey" and "lessecho" in your current directory.  Test the 
+   generated programs.
+
+7. When satisfied that it works, if you wish to install it
+   in a public place, type "make install".
+
+   The default install destinations are:
+        Executables (less, lesskey, lessecho) in /usr/local/bin
+        Documentation (less.nro, lesskey.nro) in /usr/local/man/man1
+   If you want to install any of these files elsewhere, define
+   bindir and/or mandir to the appropriate directories.
+
+
+Note to hackers: comments noting possible improvements are enclosed
+in double curly brackets {{ like this }}.
+
+(Note that the above note was originally written at a time when 
+"hackers" most commonly meant "enthusiastic and dedicated computer 
+programmers", not "persons who attempt to circumvent computer security".)
+
+
+
+=======================================================================
+INSTALLATION (MS-DOS systems only,
+              with Microsoft C, Borland C, or DJGPP)
+
+1. Move the distributed source to its own directory.
+   Depending on your compiler, you may need to convert the source 
+   to have CR-LF rather than LF as line terminators.
+
+2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE.
+   If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE.
+   If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE.
+
+3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR
+   are correct.  CC should be the name of your C compiler and
+   LIBDIR should be the directory where the C libraries reside (for
+   Microsoft C only).  If these definitions need to be changed, you can
+   either modify the definitions directly in MAKEFILE, or set your
+   environment variables CC and/or LIBDIR to override the definitions
+   in MAKEFILE.
+
+4. If you wish, you may edit DEFINES.DS to remove some optional features.
+   If you choose not to include some features in your version, you may
+   wish to edit the manual page LESS.MAN and the help page HELP.C
+   to remove the descriptions of the features which you are removing.
+
+5. Run your "make" program and watch the fun.
+   If your "make" requires a flag to import environment variables,
+   you should use that flag.
+   If your compiler runs out of memory, try running "make -n >cmds.bat" 
+   and then run cmds.bat.
+
+6. If the make succeeds, it will generate the programs "LESS.EXE" and
+   "LESSKEY.EXE" in your current directory.  Test the generated programs.
+
+7. When satisfied that it works, you may wish to install LESS.EXE and
+   LESSKEY.EXE in a directory which is included in your PATH.
+
+
+
+=======================================================================
+INSTALLATION (Windows-95, Windows-98 and Windows-NT systems only,
+              with Borland C or Microsoft Visual C++)
+
+1. Move the distributed source to its own directory.
+
+2. If you are using Borland C, rename Makefile.wnb to Makefile.
+   If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.wn to remove some optional features.
+   If you choose not to include some features in your version, you may
+   wish to edit the manual page less.man and the help page help.c
+   to remove the descriptions of the features which you are removing.
+
+5. Type "make" and watch the fun.
+
+6. If the make succeeds, it will generate the programs "less.exe" and
+   "lesskey.exe" in your current directory.  Test the generated programs.
+
+7. When satisfied that it works, if you wish to install it
+   in a public place, type "make install".
+   See step 6 of the Unix installation instructions for details
+   on how to change the default installation directories.
+
+
+
+=======================================================================
+INSTALLATION (OS/2 systems only,
+              with EMX C)
+
+1. Move the distributed source to its own directory.
+
+2. Rename Makefile.o2e to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.o2 to remove some optional features.
+   If you choose not to include some features in your version, you may
+   wish to edit the manual page less.man and the help page help.c
+   to remove the descriptions of the features which you are removing.
+
+5. Type "make" and watch the fun.
+
+6. If the make succeeds, it will generate the programs "less.exe" and
+   "lesskey.exe" in your current directory.  Test the generated programs.
+
+7. Make sure you have the emx runtime installed. You need the emx DLLs

+
+&#x1b;1mDESCRIPTION&#x1b;0m
+       &#x1b;4mLess&#x1b;24m is a program similar to &#x1b;4mmore&#x1b;24m(1), but which allows  backward  move-
+       ment in the file as well as forward movement.  Also, &#x1b;4mless&#x1b;24m does not have
+       to read the entire input file before  starting,  so  with  large  input
+       files  it  starts  up  faster  than text editors like &#x1b;4mvi&#x1b;24m(1).  &#x1b;4mLess&#x1b;24m uses
+       termcap (or terminfo on some systems), so it can run on  a  variety  of
+       terminals.   There is even limited support for hardcopy terminals.  (On
+       a hardcopy terminal, lines which should be printed at the  top  of  the
+       screen are prefixed with a caret.)
+
+       Commands  are based on both &#x1b;4mmore&#x1b;24m and &#x1b;4mvi&#x1b;24m.  Commands may be preceded by a
+       decimal number, called N in the descriptions below.  The number is used
+       by some commands, as indicated.
+
+&#x1b;1mCOMMANDS&#x1b;0m
+       In  the following descriptions, ^X means control-X.  ESC stands for the
+       ESCAPE key; for example ESC-v means the  two  character  sequence  "ES-
+       CAPE", then "v".
+
+       h or H Help:  display  a  summary of these commands.  If you forget all
+              the other commands, remember this one.
+
+       SPACE or ^V or f or ^F
+              Scroll forward N lines, default one window (see  option  -z  be-
+              low).  If N is more than the screen size, only the final screen-
+              ful is displayed.  Warning: some systems use  ^V  as  a  special
+              literalization character.
+
+       z      Like  SPACE,  but  if  N is specified, it becomes the new window
+              size.
+
+       ESC-SPACE
+              Like SPACE, but scrolls a full screenful,  even  if  it  reaches
+              end-of-file in the process.
+
+       ENTER or RETURN or ^N or e or ^E or j or ^J
+              Scroll  forward N lines, default 1.  The entire N lines are dis-
+              played, even if N is more than the screen size.
+
+       d or ^D
+              Scroll forward N lines, default one half of the screen size.  If
+              N  is specified, it becomes the new default for subsequent d and
+              u commands.
+
+       b or ^B or ESC-v
+              Scroll backward N lines, default one window (see option  -z  be-
+              low).  If N is more than the screen size, only the final screen-
+              ful is displayed.
+
+       w      Like ESC-v, but if N is specified, it  becomes  the  new  window
+              size.
+
+       y or ^Y or ^P or k or ^K
+              Scroll backward N lines, default 1.  The entire N lines are dis-
+              played, even if N is more than the screen size.   Warning:  some
+              systems use ^Y as a special job control character.
+
+       u or ^U
+              Scroll  backward  N  lines, default one half of the screen size.
+              If N is specified, it becomes the new default for  subsequent  d
+              and u commands.
+
+       J      Like j, but continues to scroll beyond the end of the file.
+
+       K or Y Like  k,  but  continues  to  scroll beyond the beginning of the
+              file.
+
+       ESC-) or RIGHTARROW
+              Scroll horizontally right N characters, default half the  screen
+              width  (see  the -# option).  If a number N is specified, it be-
+              comes the default for future RIGHTARROW and LEFTARROW  commands.
+              While  the  text  is  scrolled,  it acts as though the -S option
+              (chop lines) were in effect.
+
+       ESC-( or LEFTARROW
+              Scroll horizontally left N characters, default half  the  screen
+              width  (see  the -# option).  If a number N is specified, it be-
+              comes the default for future RIGHTARROW and LEFTARROW commands.
+
+       ESC-} or ^RIGHTARROW
+              Scroll horizontally right to show the end of  the  longest  dis-
+              played line.
+
+       ESC-{ or ^LEFTARROW
+              Scroll horizontally left back to the first column.
+
+       r or ^R or ^L
+              Repaint the screen.
+
+       R      Repaint  the  screen,  discarding  any buffered input.  That is,
+              reload the current file.  Useful if the file is  changing  while
+              it is being viewed.
+
+       F      Scroll  forward, and keep trying to read when the end of file is
+              reached.  Normally this command would be used  when  already  at
+              the  end of the file.  It is a way to monitor the tail of a file
+              which is growing while it is being  viewed.   (The  behavior  is
+              similar  to  the  "tail  -f" command.)  To stop waiting for more
+              data, enter the interrupt character (usually ^C).  On some  sys-
+              tems  you  can  also  use  ^X.   If  the input is a pipe and the
+              --exit-follow-on-close option is in effect, &#x1b;4mless&#x1b;24m will  automati-
+              cally  stop  waiting for data when the input side of the pipe is
+              closed.
+
+       ESC-F  Like F, but as soon as a line is found which  matches  the  last
+              search  pattern, the terminal bell is rung and forward scrolling
+              stops.
+
+       g or < or ESC-<
+              Go to line N in the file, default 1 (beginning of file).  (Warn-
+              ing: this may be slow if N is large.)
+
+       G or > or ESC->
+              Go  to  line N in the file, default the end of the file.  (Warn-
+              ing: this may be slow if N is large, or if N  is  not  specified
+              and standard input, rather than a file, is being read.)
+
+       ESC-G  Same  as  G, except if no number N is specified and the input is
+              standard input,  goes  to  the  last  line  which  is  currently
+              buffered.
+
+       p or % Go to a position N percent into the file.  N should be between 0
+              and 100, and may contain a decimal point.
+
+       P      Go to the line containing byte offset N in the file.
+
+       {      If a left curly bracket appears in the top line displayed on the
+              screen,  the  {  command  will  go  to  the matching right curly
+              bracket.  The matching right curly bracket is positioned on  the
+              bottom line of the screen.  If there is more than one left curly
+              bracket on the top line, a number N may be used to  specify  the
+              N-th bracket on the line.
+
+       }      If a right curly bracket appears in the bottom line displayed on
+              the screen, the } command will go to  the  matching  left  curly
+              bracket.   The  matching left curly bracket is positioned on the
+              top line of the screen.  If there is more than one  right  curly
+              bracket  on  the  bottom line, a number N may be used to specify
+              the N-th bracket on the line.
+
+       (      Like {, but applies to parentheses rather than curly brackets.
+
+       )      Like }, but applies to parentheses rather than curly brackets.
+
+             Like {, but applies to square brackets rather than curly  brack-
+              ets.
+
+             Like  }, but applies to square brackets rather than curly brack-
+              ets.
+
+       ESC-^F Followed by two characters, acts like {, but uses the two  char-
+              acters  as  open and close brackets, respectively.  For example,
+              "ESC ^F < >" could be used to go forward to the > which  matches
+              the < in the top displayed line.
+
+       ESC-^B Followed  by two characters, acts like }, but uses the two char-
+              acters as open and close brackets, respectively.   For  example,
+              "ESC ^B < >" could be used to go backward to the < which matches
+              the > in the bottom displayed line.
+
+       m      Followed by any lowercase or uppercase letter, marks  the  first
+              displayed  line  with  that letter.  If the status column is en-
+              abled via the -J option, the  status  column  shows  the  marked
+              line.
+
+       M      Acts  like  m,  except  the last displayed line is marked rather
+              than the first displayed line.
+
+       '      (Single quote.)  Followed by any lowercase or uppercase  letter,
+              returns  to  the  position which was previously marked with that
+              letter.  Followed by another single quote, returns to the  posi-
+              tion  at  which  the last "large" movement command was executed.
+              Followed by a ^ or $, jumps to the beginning or end of the  file
+              respectively.   Marks are preserved when a new file is examined,
+              so the ' command can be used to switch between input files.
+
+       ^X^X   Same as single quote.
+
+       ESC-m  Followed by any lowercase or uppercase letter, clears  the  mark

+.SH DESCRIPTION
+.I Less
+is a program similar to
+.IR more (1),
+but which allows backward movement
+in the file as well as forward movement.
+Also,
+.I less
+does not have to read the entire input file before starting,
+so with large input files it starts up faster than text editors like
+.IR vi (1).
+.I Less
+uses termcap (or terminfo on some systems),
+so it can run on a variety of terminals.
+There is even limited support for hardcopy terminals.
+(On a hardcopy terminal, lines which should be printed at the top
+of the screen are prefixed with a caret.)
+.PP
+Commands are based on both
+.I more
+and
+.IR vi .
+Commands may be preceded by a decimal number,
+called N in the descriptions below.
+The number is used by some commands, as indicated.
+.
+.SH COMMANDS
+In the following descriptions, ^X means control-X.
+ESC stands for the ESCAPE key; for example ESC-v means the
+two character sequence "ESCAPE", then "v".
+.IP "h or H"
+Help: display a summary of these commands.
+If you forget all the other commands, remember this one.
+.IP "SPACE or ^V or f or ^F"
+Scroll forward N lines, default one window (see option \-z below).
+If N is more than the screen size, only the final screenful is displayed.
+Warning: some systems use ^V as a special literalization character.
+.IP "z"
+Like SPACE, but if N is specified, it becomes the new window size.
+.IP "ESC-SPACE"
+Like SPACE, but scrolls a full screenful, even if it reaches
+end-of-file in the process.
+.IP "ENTER or RETURN or ^N or e or ^E or j or ^J"
+Scroll forward N lines, default 1.
+The entire N lines are displayed, even if N is more than the screen size.
+.IP "d or ^D"
+Scroll forward N lines, default one half of the screen size.
+If N is specified, it becomes the new default for
+subsequent d and u commands.
+.IP "b or ^B or ESC-v"
+Scroll backward N lines, default one window (see option \-z below).
+If N is more than the screen size, only the final screenful is displayed.
+.IP "w"
+Like ESC-v, but if N is specified, it becomes the new window size.
+.IP "y or ^Y or ^P or k or ^K"
+Scroll backward N lines, default 1.
+The entire N lines are displayed, even if N is more than the screen size.
+Warning: some systems use ^Y as a special job control character.
+.IP "u or ^U"
+Scroll backward N lines, default one half of the screen size.
+If N is specified, it becomes the new default for
+subsequent d and u commands.
+.IP "J"
+Like j, but continues to scroll beyond the end of the file.
+.IP "K or Y"
+Like k, but continues to scroll beyond the beginning of the file.
+.IP "ESC-) or RIGHTARROW"
+Scroll horizontally right N characters, default half the screen width
+(see the \-# option).
+If a number N is specified, it becomes the default for future RIGHTARROW
+and LEFTARROW commands.
+While the text is scrolled, it acts as though the \-S option
+(chop lines) were in effect.
+.IP "ESC-( or LEFTARROW"
+Scroll horizontally left N characters, default half the screen width
+(see the \-# option).
+If a number N is specified, it becomes the default for future RIGHTARROW
+and LEFTARROW commands.
+.IP "ESC-} or ^RIGHTARROW"
+Scroll horizontally right to show the end of the longest displayed line.
+.IP "ESC-{ or ^LEFTARROW"
+Scroll horizontally left back to the first column.
+.IP "r or ^R or ^L"
+Repaint the screen.
+.IP R
+Repaint the screen, discarding any buffered input.
+That is, reload the current file.
+Useful if the file is changing while it is being viewed.
+.IP "F"
+Scroll forward, and keep trying to read when the
+end of file is reached.
+Normally this command would be used when already at the end of the file.
+It is a way to monitor the tail of a file which is growing
+while it is being viewed.
+(The behavior is similar to the "tail \-f" command.)
+To stop waiting for more data, enter the interrupt character (usually ^C).
+On some systems you can also use ^X.
+If the input is a pipe and the \-\-exit-follow-on-close option is in effect,
+.I less
+will automatically stop waiting for data when the input side 
+of the pipe is closed.
+.IP "ESC-F"
+Like F, but as soon as a line is found which matches
+the last search pattern, the terminal bell is rung
+and forward scrolling stops.
+.IP "g or < or ESC-<"
+Go to line N in the file, default 1 (beginning of file).
+(Warning: this may be slow if N is large.)
+.IP "G or > or ESC->"
+Go to line N in the file, default the end of the file.
+(Warning: this may be slow if N is large,
+or if N is not specified and
+standard input, rather than a file, is being read.)
+.IP "ESC-G"
+Same as G, except if no number N is specified and the input is standard input,
+goes to the last line which is currently buffered.
+.IP "p or %"
+Go to a position N percent into the file.
+N should be between 0 and 100, and may contain a decimal point.
+.IP "P"
+Go to the line containing byte offset N in the file.
+.IP "{"
+If a left curly bracket appears in the top line displayed
+on the screen,
+the { command will go to the matching right curly bracket.
+The matching right curly bracket is positioned on the bottom
+line of the screen.
+If there is more than one left curly bracket on the top line,
+a number N may be used to specify the N-th bracket on the line.
+.IP "}"
+If a right curly bracket appears in the bottom line displayed
+on the screen,
+the } command will go to the matching left curly bracket.
+The matching left curly bracket is positioned on the top
+line of the screen.
+If there is more than one right curly bracket on the bottom line,
+a number N may be used to specify the N-th bracket on the line.
+.IP "("
+Like {, but applies to parentheses rather than curly brackets.
+.IP ")"
+Like }, but applies to parentheses rather than curly brackets.
+.IP ""
+Like {, but applies to square brackets rather than curly brackets.
+.IP ""
+Like }, but applies to square brackets rather than curly brackets.
+.IP "ESC-^F"
+Followed by two characters,
+acts like {, but uses the two characters as open and close brackets,
+respectively.
+For example, "ESC ^F < >" could be used to
+go forward to the > which matches the < in the top displayed line.
+.IP "ESC-^B"
+Followed by two characters,
+acts like }, but uses the two characters as open and close brackets,
+respectively.
+For example, "ESC ^B < >" could be used to
+go backward to the < which matches the > in the bottom displayed line.
+.IP m
+Followed by any lowercase or uppercase letter,
+marks the first displayed line with that letter.
+If the status column is enabled via the \-J option,
+the status column shows the marked line.
+.IP M
+Acts like m, except the last displayed line is marked
+rather than the first displayed line.
+.IP "'"
+(Single quote.)
+Followed by any lowercase or uppercase letter, returns to the position which
+was previously marked with that letter.
+Followed by another single quote, returns to the position at
+which the last "large" movement command was executed.
+Followed by a ^ or $, jumps to the beginning or end of the
+file respectively.
+Marks are preserved when a new file is examined,

+.TH LESSECHO 1 "Version 608: 22 Jul 2022"
+.SH NAME
+lessecho \- expand metacharacters
+.SH SYNOPSIS
+.B lessecho
+.I "-ox -cx -pn -dn -mx -nn -ex -a file ..."
+.SH "DESCRIPTION"
+.I lessecho
+is a program that simply echos its arguments on standard output.
+But any metacharacter in the output is preceded by an "escape"
+character, which by default is a backslash.
+.SH OPTIONS
+A summary of options is included below.
+.TP
+.B \-ex
+Specifies "x", rather than backslash, to be the escape char for metachars.
+If x is "-", no escape char is used and arguments containing metachars
+are surrounded by quotes instead.
+.TP
+.B \-ox
+Specifies "x", rather than double-quote, to be the open quote character,
+which is used if the \-e- option is specified.
+.TP
+.B \-cx
+Specifies "x" to be the close quote character.
+.TP
+.B \-pn
+Specifies "n" to be the open quote character, as an integer.
+.TP
+.B \-dn
+Specifies "n" to be the close quote character, as an integer.
+.TP
+.B \-mx
+Specifies "x" to be a metachar.
+By default, no characters are considered metachars.
+.TP
+.B \-nn
+Specifies "n" to be a metachar, as an integer.
+.TP
+.B \-fn
+Specifies "n" to be the escape char for metachars, as an integer.
+.TP
+.B \-a
+Specifies that all arguments are to be quoted.
+The default is that only arguments containing metacharacters are quoted.

+ *  If no input file is specified, standard input is used.
+ *  If no output file is specified, $HOME/.less is used.
+ *
+ *  The .less file is used to specify (to "less") user-defined

+ *  keystrokes may be bound to an existing less function.
+ *
+ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 
+ *
+ *  The input file is an ascii file consisting of a 
+ *  sequence of lines of the form:
+ *          string <whitespace> action chars <newline>
+ *
+ *      "string" is a sequence of command characters which form
+ *              the new user-defined command.  The command
+ *              characters may be:
+ *              1. The actual character itself.
+ *              2. A character preceded by ^ to specify a
+ *                 control character (e.g. ^X means control-X).
+ *              3. A backslash followed by one to three octal digits
+ *                 to specify a character by its octal value.
+ *              4. A backslash followed by b, e, n, r or t
+ *                 to specify \b, ESC, \n, \r or \t, respectively.
+ *              5. Any character (other than those mentioned above) preceded 
+ *                 by a \ to specify the character itself (characters which
+ *                 must be preceded by \ include ^, \, and whitespace.
+ *      "action" is the name of a "less" action, from the table below.
+ *      "chars" is an optional sequence of characters which is treated
+ *              as keyboard input after the command is executed.
+ *
+ *      Blank lines and lines which start with # are ignored, 
+ *      except for the special control lines:
+ *              #command        Signals the beginning of the command
+ *                              keys section.
+ *              #line-edit      Signals the beginning of the line-editing
+ *                              keys section.
+ *              #env            Signals the beginning of the environment

+ *                              causes all default keys to be disabled.
+ *
+ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 
+ *
+ *      The output file is a non-ascii file, consisting of a header,
+ *      one or more sections, and a trailer.
+ *      Each section begins with a section header, a section length word
+ *      and the section data.  Normally there are three sections:
+ *              CMD_SECTION     Definition of command keys.
+ *              EDIT_SECTION    Definition of editing keys.
+ *              END_SECTION     A special section header, with no 
+ *                              length word or section data.
+ *
+ *      Section data consists of zero or more byte sequences of the form:
+ *              string <0> <action>
+ *      or
+ *              string <0> <action|A_EXTRA> chars <0>
+ *
+ *      "string" is the command string.
+ *      "<0>" is one null byte.
+ *      "<action>" is one byte containing the action code (the A_xxx value).
+ *      If action is ORed with A_EXTRA, the action byte is followed
+ *              by the null-terminated "chars" string.

+       lesskey - customize key bindings for less
+
+&#x1b;1mSYNOPSIS (deprecated)&#x1b;0m
+       &#x1b;1mlesskey -o output -- input&#x1b;0m
+       &#x1b;1mlesskey --output=output -- input&#x1b;0m

+
+&#x1b;1mSCOPE&#x1b;0m
+       This document describes the format of the &#x1b;4mlesskey&#x1b;24m source file, which is
+       used by &#x1b;4mless&#x1b;24m version 582 and later.  In previous versions  of  &#x1b;4mless&#x1b;24m,  a
+       separate  program called &#x1b;4mlesskey&#x1b;24m was used to compile the &#x1b;4mlesskey&#x1b;24m source
+       file into a format understood by &#x1b;4mless&#x1b;24m.  This  compilation  step  is  no
+       longer  required  and  the &#x1b;4mlesskey&#x1b;24m program is therefore deprecated, al-
+       though the file format remains supported by &#x1b;4mless&#x1b;24m itself.
+
+&#x1b;1mDESCRIPTION&#x1b;0m
+       A &#x1b;4mlesskey&#x1b;24m file specifies a set of key bindings  and  environment  vari-
+       ables to be used by subsequent invocations of &#x1b;4mless.&#x1b;0m
+
+&#x1b;1mFILE FORMAT&#x1b;0m
+       The  input  file consists of one or more &#x1b;4msections.&#x1b;24m  Each section starts
+       with a line that identifies the type  of  section.   Possible  sections
+       are:
+
+       #command
+              Customizes command key bindings.
+
+       #line-edit
+              Customizes line-editing key bindings.
+
+       #env   Defines environment variables.
+
+       Blank  lines  and  lines which start with a pound sign (#) are ignored,
+       except as noted below.
+
+&#x1b;1mCOMMAND SECTION&#x1b;0m
+       The command section begins with the line
+
+       #command
+
+       If the command section is the first section in the file, this line  may
+       be omitted.  The command section consists of lines of the form:
+
+            &#x1b;4mstring&#x1b;24m <whitespace> &#x1b;4maction&#x1b;24m extra-string <newline>
+
+       Whitespace  is  any  sequence  of  one or more spaces and/or tabs.  The
+       &#x1b;4mstring&#x1b;24m is the command key(s) which invoke the action.  The  &#x1b;4mstring&#x1b;24m  may
+       be a single command key, or a sequence of up to 15 keys.  The &#x1b;4maction&#x1b;24m is
+       the name of the less action, from the list below.   The  characters  in
+       the  &#x1b;4mstring&#x1b;24m may appear literally, or be prefixed by a caret to indicate
+       a control key.  A backslash followed by one to three octal  digits  may
+       be  used  to  specify a character by its octal value.  A backslash fol-
+       lowed by certain characters specifies input characters as follows:
+
+            \b   BACKSPACE   (0x08)
+            \e   ESCAPE      (0x1B)
+            \n   NEWLINE     (0x0A)
+            \r   RETURN      (0x0D)
+            \t   TAB         (0x09)
+
+            \k followed by a single character represents the char(s)  produced
+            when one of these keys is pressed:
+
+            \kb   BACKSPACE (the BACKSPACE key)
+            \kB   ctrl-BACKSPACE
+            \kd   DOWN ARROW
+            \kD   PAGE DOWN
+            \ke   END
+            \kh   HOME
+            \ki   INSERT
+            \kl   LEFT ARROW
+            \kL   ctrl-LEFT ARROW

+            \kx   DELETE
+            \kX   ctrl-DELETE
+            \k1   F1
+
+
+            A backslash followed by any other character indicates that charac-
+            ter is to be taken literally.  Characters which must  be  preceded
+            by backslash include caret, space, tab and the backslash itself.
+
+            An  action may be followed by an "extra" string.  When such a com-
+            mand is entered while running &#x1b;4mless&#x1b;24m, the action is  performed,  and
+            then  the  extra  string is parsed, just as if it were typed in to
+            &#x1b;4mless&#x1b;24m.  This feature can be used in certain  cases  to  extend  the
+            functionality  of  a  command.   For example, see the "{" and ":t"
+            commands in the example below.  The extra  string  has  a  special
+            meaning  for the "quit" action: when &#x1b;4mless&#x1b;24m quits, the first charac-
+            ter of the extra string is used as its exit status.
+
+&#x1b;1mEXAMPLE&#x1b;0m
+       The following input file describes the set of default command keys used
+       by  &#x1b;4mless&#x1b;24m.   Documentation on each command can be found in the man page,
+       under the key sequence which invokes the command.

+.TH LESSKEY 1 "Version 608: 22 Jul 2022"
+.SH NAME
+lesskey \- customize key bindings for less
+.SH "SYNOPSIS (deprecated)"
+.B "lesskey \-o output \-\- input"
+.br
+.B "lesskey \-\-output=output \-\- input"
+.br
+.B "lesskey \-V"
+.br
+.B "lesskey \-\-version"
+.SH SCOPE
+This document describes the format of the 
+.I lesskey
+source file, which is used by
+.I less
+version 582 and later.
+In previous versions of 
+.IR less ,
+a separate program called
+.I lesskey
+was used to compile the 
+.I lesskey 
+source file into a format understood by
+.IR less .
+This compilation step is no longer required and the
+.I lesskey
+program is therefore deprecated, although the file format remains supported by
+.I less
+itself.
+.PP
+.SH DESCRIPTION
+A
+.I lesskey
+file specifies a set of key bindings and environment variables
+to be used by subsequent invocations of
+.I less.
+.SH FILE FORMAT
+The input file consists of one or more
+.I sections.
+Each section starts with a line that identifies the type of section.
+Possible sections are:
+.IP #command
+Customizes command key bindings.
+.IP #line-edit
+Customizes line-editing key bindings.
+.IP #env
+Defines environment variables.
+.PP
+Blank lines and lines which start with a pound sign (#) are ignored,
+except as noted below.
+.
+.SH "COMMAND SECTION"
+The command section begins with the line
+.sp
+#command
+.sp
+If the command section is the first section in the file,
+this line may be omitted.
+The command section consists of lines of the form:
+.sp
+	\fIstring\fP <whitespace> \fIaction\fP extra-string <newline>
+.sp
+Whitespace is any sequence of one or more spaces and/or tabs.
+The \fIstring\fP is the command key(s) which invoke the action.
+The \fIstring\fP may be a single command key, or a sequence of up to 15 keys.
+The \fIaction\fP is the name of the less action, from the list below.
+The characters in the \fIstring\fP may appear literally, or be
+prefixed by a caret to indicate a control key.
+A backslash followed by one to three octal digits may be used to
+specify a character by its octal value.
+A backslash followed by certain characters specifies input
+characters as follows:
+.RS 5m
+.TS
+l l l.
+\eb	BACKSPACE	(0x08)
+\ee	ESCAPE	(0x1B)
+\en	NEWLINE	(0x0A)
+\er	RETURN	(0x0D)
+\et	TAB	(0x09)
+.TE
+.sp
+\ek followed by a single character represents the char(s) produced when one of these keys is pressed:
+.TS
+l l.
+\ekb	BACKSPACE (the BACKSPACE key)
+\ekB	ctrl-BACKSPACE
+\ekd	DOWN ARROW
+\ekD	PAGE DOWN
+\eke	END
+\ekh	HOME
+\eki	INSERT
+\ekl	LEFT ARROW
+\ekL	ctrl-LEFT ARROW
+\ekr	RIGHT ARROW
+\ekR	ctrl-RIGHT ARROW
+\ekt	BACKTAB
+\eku	UP ARROW
+\ekU	PAGE UP
+\ekx	DELETE
+\ekX	ctrl-DELETE
+\ek1	F1
+.TE
+
+.PP
+A backslash followed by any other character indicates that character is
+to be taken literally.
+Characters which must be preceded by backslash include
+caret, space, tab and the backslash itself.
+.PP
+An action may be followed by an "extra" string.
+When such a command is entered while running
+.IR less ,
+the action is performed, and then the extra
+string is parsed, just as if it were typed in to
+.IR less .
+This feature can be used in certain cases to extend
+the functionality of a command.
+For example, see the "{" and ":t" commands in the example below.
+The extra string has a special meaning for the "quit" action:
+when
+.I less
+quits, the first character of the extra string is used as its exit status.
+.
+.SH EXAMPLE
+The following input file describes the set of
+default command keys used by 
+.IR less .
+Documentation on each command can be found in the
+.less
+man page, under the key sequence which invokes the command.
