+Version 10.0.0 (2021-10-16)
+---------------------------
+.Breaking Changes
+AsciiDoc.py has been rewritten to be a https://pypi.org/project/asciidoc/proper Python package, installable via pip. Downloading and running asciidoc from the repo is not recommended, but can be done through `python3 -m asciidoc` or `python3 -m asciidoc.a2x`. CLI usage should remain the same where both `asciidoc` and `a2x` CLI commands are available after pip installation. Support for overriding the bundled *.conf files is done through CLI flags, environment variables, etc., and not through directly editing the files within the installation. Importing asciidoc should no longer require the `asciidocapi.py` script, and can be done through regular python import, e.g. `import asciidoc; asciidoc.execute(...)`.
+
+The APIs of the asciidoc and a2x scripts are now considered "provisional" with no guarantee of BC between releases with the exception of the `asciidoc.execute` method. Please post an issue on our tracker for any method you directly rely on and would like to have BC for.
+
+.Features
+- Install using `pip install asciidoc`
+
+.Miscellaneous
+- Changed website domain to https://asciidoc-py.github.io/. The old domain will redirect for a period of time, but will be updated at some point to point at website created by the https://asciidoc-wg.eclipse.org/AsciiDoc Working Group.
+
+.Testing
+- Test against 3.10 stable
+

+
+Version 9.1.0 (2021-02-08)

+--------------------------
+.Release highlights
+No major enhancements but quite a few bug fixes which, among other
+things, fixes Jython compatibility and improves Windows compatibility.
+
+.All additions and changes
+- Vim syntax highlighter: highlight entity refs in macro arguments.
+- Added files with `.asciidoc` extension to Vim file type detection.
+  http://groups.google.com/group/asciidoc/browse_thread/thread/a9762e21ec0cc244/5d3a4ebf20e6847ePatch
+  submitted by Dag Wiers.
+- Added 'replacement3' substitution to enable
+  http://groups.google.com/group/asciidoc/browse_thread/thread/843d7d3d671006fb/25628e14c829db3fODT
+  whitespace processing.
+- Added 'unbreakable' option to XHTML and HTML 5 backends.
+- Implemented toc:: block macro and 'toc-placement' attribute for
+  HTML backends to allow the Table of Contents placement to be set
+  manually by the author.
+- Added FAQs: 'How can I control page breaks when printing HTML
+  outputs?' and 'Is it possible to reposition the Table of Contents
+  in HTML outputs?'.
+- Added `--backend` and `--backend-opts` options to the 'a2x' command
+  to allow 'a2x' to use backend plugin code extensions.
+  http://groups.google.com/group/asciidoc/browse_thread/thread/b8e93740b7cd0e1d/b5e0b83fe37ae31aPatch
+  submitted by Lex Trotman.

+  http://groups.google.com/group/asciidoc/browse_thread/thread/3d06b0105dfbb780/8c60eb7a62f522e4args
+  block attribute to source highlight blocks to allow arbitrary
+  parameters to be passed to the source highlighters.
+- If the 'ascii-ids' attribute is defined then non-ascii characters in
+  auto-generated IDs
+  http://groups.google.com/group/asciidoc/browse_thread/thread/33e99b78e2472122are
+  replaced by their nearest ascii equivalents (to work around DocBook
+  processor limitations).
+- Added global 'blockname' attribute which is dynamically updated to
+  identify the current block.  See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/8200e29815c40f72discussion
+  list.
+- 'xhtml11', 'html5' backends: Include book part TOC entries for

+  backends implemented as external plugins can compile the manual. See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/849e5ea91f43adf2discussion
+  list.
+- If the delimited block 'skip' option is set then do not consume
+  block title and attributes. This makes it possible for the comment
+  delimited blocks to use an attribute list (previously the comment
+  delimited block was hardwired to skip preceding attributes and
+  titles). See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/e92a75abcc382701discussion
+  list.
+- Added `backend-confdir` intrinsic attribute.
+
+.Bug fixes

+  submitted by Dag Wieers.
+- *FIXED*: Use configured normal substitution in preference to the
+  default one.
+- *FIXED*: The 'eval' block macro would execute multiple times if it
+  evaluated to 'None'.
+- *FIXED*: Duplicated entries in TOC of large document.
+  http://groups.google.com/group/asciidoc/browse_thread/thread/103445ab9d95cb0cPatch

+- *FIXED*: Python 2.4 backward
+  http://code.google.com/p/asciidoc/issues/detail?id=9incompatibility.
+- *FIXED*: 8.6.6 regression broke Jython compatibility.  See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/4608b77ec289f6c4discussion
+  list.
+- *FIXED*: Leaky file handles in a2x and music and latex filters which
+  created incompatibility problems for Jython.
+- *FIXED*: All Python filters are executed with the same Python
+  interpreter that executes the asciidoc parent (previously filters
+  were hardwired to execute the 'python' interpreter). This prevents
+  http://groups.google.com/group/asciidoc/browse_thread/thread/14e8fcb289a135b/3af3b4e57b827c78?lnk=gst&q=archlinux#3af3b4e57b827c78Python
+  mix-ups.

+  caused shelled commands to fail e.g. the 'data-uri' attribute
+  failure.
+
+
+Version 8.6.6 (2011-09-04)
+--------------------------
+.Release highlights
+- The AsciiDoc plugin architecture has been enhanced, unified and
+  extended:
+  * Plugin commands have been added to the asciidoc(1) `--backend`
+    option.
+  * An asciidoc(1) `--theme` option has been implemented to specify a
+    theme and to manage theme plugins.
+  * A plugin 'build' command (for creating plugins) added.
+  * 'build', 'install', 'list' and 'remove' plugin commands are all
+    recognized by asciidoc(1) `--backend`, `--filter` and `--theme`
+    options.
+- A security update by Kenny MacDermid removes the use of `eval()` on
+  untrusted input (to disallow code malicious execution).
+
+.All additions and changes
+- 'xhtml11', 'html5': Made verse and quote block text darker to print
+  legibly in Google Chrome browser.
+- Added plugin 'build' command for plugin file creation.
+- Merged `--help plugins` back to `--help manpage` so it matches the
+  asciidoc(1) manpage.
+- The `--filter` command-line option can specify the name of filters
+  that will be unconditionally loaded.
+- If a filter directory contains a file named `__noautoload__` then
+  the filter is not automatically loaded (you can used the `--filter`
+  command-line option to override this behavior).
+- tests: Add Italian language tests.  Patch submitted by Simon
+  Ruderich. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/5e2e6f4dd740d51a
+- tests: Add tests for localized man pages.  Patch submitted by Simon
+  Ruderich. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/5e2e6f4dd740d51a
+- If the section name is prefixed with a '+' character then the
+  section contents is appended to the contents of an already existing
+  same-named section (the default behavior is to replace the the
+  section).
+- If a configuration file section named 'docinfo' is loaded then it
+  will be included in the document header.  Typically the 'docinfo'
+  section name will be prefixed with a '+' character so that it is
+  appended to (rather than replace) other 'docinfo' sections.
+- Added `{sp}` intrinsic attribute for single space character.  See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/a839aa01db0765d2
+- Fixed TOC and footnotes generator. Patch submitted by Will.  See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/734ac5afed736987
+- The `asciidoc-confdir` attribute is set to the asciidoc executable
+  directory if it contains global configuration files i.e. a local
+  asciidoc installation.
+- asciidoc now throws an error instead of just a warning of the
+  backend configuration file is not found.
+- latex filter: write MD5 file after successful PNG file generation.
+  Always delete temp files irrespective of outcome.

+- Added verbose message for `ifeval::` macro evaluation.
+- Added test case for `ifeval::` evaluation.
+- Security update to remove the use of `eval()` on untrusted input (to

+- a2x: Pass `--format` option value to asciidoc as 'a2x-format'
+  attribute.  Patch submitted by Lex Trotman
+  (http://groups.google.com/group/asciidoc/browse_thread/thread/3e177b84bc133ca9/659796dfadad30ea?lnk=gst&q=a2x+format#659796dfadad30ea).
+- Added two FAQs submitted by Lex Trotman. See:

+  from the theme icons directory (if they exist) will be embedded in
+  the generated document.
+- Added optional 'warnings' argument to include macros.
+- The asciidoc `--verbose` option now prints file inclusion messages.
+- xhtml11, html5: Remove necessity for separate manpage CSS files.
+- Added 'css-signature' attribute to tests.
+- Add 'css-signature' attribute to set a CSS signature for the
+  document.  Patch submitted by Peg Russell, see:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/bacbf8aeb8ad6a3a

+  content does not obscure the the TOC.  Patch submitted by Lionel
+  Orry, see: http://code.google.com/p/asciidoc/issues/detail?id=8
+
+.Bug fixes
+- *FIXED*: Plugin install command: Delete backend directory is install
+  fails.
+- *FIXED*: Plugin install command: Fixed bug extracting binary files
+  on Windows (reported by Jean-Michel Inglebert).
+- *FIXED*: tests: Skip blank sections in testasciidoc.conf test
+  configuration file instead of throwing an exception (reported by
+  Jean-Michel Inglebert).
+- *FIXED*: If a plugin Zip file does not contain file permissions
+  (probably because it was created under Windows) then install it
+  using the default permissions.
+- *FIXED*: Fixed missing quote in preceding LaTeX filter patch. Fix
+  submitted by Simon Ruderich. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/6436788a10561851
+- *FIXED*: Some path attributes were processed as escaped Python
+  strings which could result in corrupted path names with backslash
+  separated Windows path names. Reported by Will. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/e8f3938bcb4c8bb4/44d13113a35738ef
+- *FIXED*: Vertically spanned table cells resulted in incorrect column

+  by Fabrice Flore-Thebault.  See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/eaf25f21d1da180a
+
+
+Version 8.6.5 (2011-05-20)
+--------------------------
+.Release highlights
+- The addition of an 'html5' backend to generate HTML 5 output. Apart
+  from the inclusion of 'audio' and 'video' block macros the 'html5'
+  backend is functionally identical to the 'xhtml11' backend.
+
+- A new 'flask' theme for 'xhtml11' and 'html5' backends inspired by
+  the http://flask.pocoo.org/docs/Flask website styling (see 'toc2'
+  example in the next item below).
+
+- The new 'toc2' attribute generates a table of contents in
+  the left hand margin ('xhtml11' and 'html5' backends).
+  link:article-html5-toc2.htmlThis example was generated using
+  the following command:
+
+  asciidoc -b html5 -a icons -a toc2 -a theme=flask article.txt
+
+- `a2x(1)` now has a flexible mechanism for copying arbitrary
+  resource files to HTML based outputs -- this is very handy for
+  generating EPUB files with embedded fonts and other resources.
+
+  * The `a2x(1)` `--resource` option can be used to inject any file
+    into EPUB output documents e.g. CSS resources such as fonts and
+    background images.
+  * Explicitly specified resources are added to the EPUB OPF manifest
+    automatically.
+  * You can explicitly specify file extension MIME types.
+  * The enhanced resource processing works around a couple of DocBook
+    XSL bugs (see link:epub-notes.htmlEPUB Notes).
+
+.All additions and changes
+- A new 'flask' theme for 'xhtml11' and 'html5' backends.  A shameless
+  knock-off of the http://flask.pocoo.org/docs/Flask website
+  styling.
+- Added HTML 5 article with 'toc2' table of contents to the example on
+  the AsciiDoc website home page.
+- Added 'filters' and 'topics' help topics.  Fixed documentation
+  errors in help text.  Patch submitted by Lionel Orry, see:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/9da9d48a6461ff14
+- Pass parent configuration files, command-line attributes and header
+  attributes to table asciidoc filters. Based on patch submitted by
+  Simon Ruderich, see:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/5c792cbb395b753b
+- Allow a 'title' attribute entry in the document header so that HTML
+  backends can set the 'title' element separately from the displayed
+  document title (the 'doctitle' attribute).
+- Pass 'lang' attribute to 'asciidoc' table style filter. Patch
+  submitted by Simon Ruderich, see:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/e2100b7cb29283ce
+- xhtml11,html5: Added 'toc2' attribute which generates a scrollable
+  table of contents in the left hand margin. Based on customized CSS
+  written by Suraj Kurapati, see
+  http://groups.google.com/group/asciidoc/browse_thread/thread/c5e30ee5555877f5
+- Added 'asciidoc-confdir' intrinsic attribute which expands to the
+  global conf directory.
+- Documented that you can specify multiple CSS files with the a2x(1)
+  `--stylesheet` command option. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/baf3218551d05a05
+- Improved xhtml11 backend's table of contents generation latency.
+  Patch submitted by Hongli Lai. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/5a7fe64fbfd65ad
+- Added html5 backend.
+- For consistency converted all DOS formatted configuration and text
+  files to UNIX format.
+- html4: Added ability to use 'role' attribute with most block
+  elements. Patch contributed by Simon Ruderich.  See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/5620ba634fdb030a
+- Added Dutch language configuration file and accompanying test file
+  (contributed by Dag Wieers, see
+  http://groups.google.com/group/asciidoc/browse_thread/thread/f969b9ce987d7f5d).
+- Configuration files are loaded in two passes when the -e
+  command-line option is used (the same behavior as when the -e option
+  is not used). Patch submitted by haad. See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/cd0f47495fd04181
+  and
+  http://code.google.com/p/asciidoc/issues/detail?id=6&q=label%3APriority-Medium
+- Documented how to include embedded fonts in an EPUB document.
+- a2x: Added `.<ext>=<mimetype>` resource specifier syntax.
+- a2x: Enable admonition icons in example EPUBs.
+- a2x: allow environment variables and tilde home directories in
+  resource manifest files.
+- a2x: don't process non-existent resource directories.
+- a2x: assume resource option is a directory if the name ends with a
+  directory separator.
+- a2x: Added a new syntax to the `--resource` option specifier which
+  allows the destination path to be specified.
+- a2x: Copy resources referenced in the OPF and resources referenced
+  by the generated HTML (in theory DocBook XSL should ensure they are
+  identical but this is not always the case e.g.
+  http://sourceforge.net/tracker/?func=detail&atid=373747&aid=2854075&group_id=21935).
+- Drop border from callout list image links.
+- html4: Moved manpage NAME section out of header so that the name
+  section is rendered when the asciidoc(1) `--no-header-footer` option
+  is specified (so that manpages processed blogpost include the NAME
+  section).
+- Vim syntax highlighter: TODO markers now appear in list items and
+  literal paragraphs and blocks.
+- Constrained quotes can now be bounded on the left by a } character.
+  See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/b24cc3362f35b801
+- Added text-decoration roles (underline, overline, line-through,
+  blink) for xhtml11 and html5 outputs.
+
+.Bug fixes
+- *FIXED*: epubcheck 1.1 previously issued a warning for files not
+  registered in the manifest (epubcheck 1.0.5 did not). This resulted
+  in a problem compiling the adventures-of-sherlock-holmes.txt example
+  (the `underline.png` resource was not in the manifest).
+
+
+Version 8.6.4 (2011-02-20)
+--------------------------
+.Additions and changes

+- Vim Syntax highlighter: Highlight closing OpenBlocks which
+  immediately follow a literal paragraph.
+- Changed UNIX `/dev/null` to OS independent `os.devnull` in filters
+  code.  Suggested by Henrik Maier:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/5ac8e8ea895147e9
+- Vim syntax highlighter: Single and double quoted text now highlights
+  correctly when preceded by an attributes list.
+- Added Ukrainian language file (`lang-uk.conf`). Added double-quote
+  characters to Russian language file.conf). Patches contributed by
+  Lavruschenko Oleksandr, see
+  http://groups.google.com/group/asciidoc/browse_thread/thread/e15282f072413940
+- Single and double quote characters are now set using the `{lsquo}`,
+  `{rsquo}`, `{ldquo}` and `{rdquo}` attributes. This makes is easy to
+  customise language specific quotes. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/e15282f072413940
+- Implemented 'conf-files' attribute to allow configuration files to
+  be specified in the source document. Suggested by Lex Trotman, see:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/b11066a828ab45b9
+
+.Bug fixes
+- *FIXED*: Auto-generated section title ids are now Unicode aware.
+- *FIXED*: Setting 'quotes' configuration entries using document
+  attribute entries failed if the attribute entry was not in the
+  document header.  See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/a1dd0562dee8b939
+- *FIXED*: If the input and output file names were different then the
+  output file name was incorrectly used to synthesize 'docinfo' file
+  names. Reported by Christian Zuckschwerdt.
+- *FIXED*: An error can occur when more than one consecutive quotes
+  are defined as a blank string. Reported by Peggy Russell.
+- *FIXED*: Encoding error in automatically generated author initials.
+  Patch submitted by Xin Wang. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/f44615dca0b834e9
+
+
+Version 8.6.3 (2010-11-14)
+--------------------------
+.Additions and changes
+- Added and 'unbreakable' option to bulleted and numbered lists
+  (thanks to Henrik Maier for this patch).
+- Added `ifeval::` system macro (thanks to Henrik Maier for
+  suggesting this feature).
+- The image 'scale' attribute sets the DocBook 'imagedata' element
+  'scale' attribute.  Patch submitted by Henrik Maier.
+- DocBook 'preface', 'colophon' and 'dedication' style section titles
+  now work. Based on patch submitted by Henrik Maier.
+- 'a2x': Do not inject xsltproc parameters if they were specified on
+  the command-line (parameter double-ups generate xsltproc 'Global
+  parameter already defined' errors).
+- 'a2x': Refactored xsltproc parameter injection.
+- 'a2x': articles chunked at section level by default.
+- 'attributes', 'titles' and 'specialcharacters' sections are now read
+  from the local `asciidoc.conf` file before the header is parsed.
+  This fixes a regression problem. See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/1b3f88f1f8118ab3
+- Document header attributes take precedence over configuration file
+  attributes.
+- Refactored 'music', 'graphviz' and 'latex' filter configurations.
+- Refactored source filter configuration and added literal paragraph
+  source style.
+- Separated paragraph styles from paragraph syntax -- any style can be
+  applied to any syntax.
+- Added 'listing' and 'quote' paragraph styles.
+- Renamed paragraph 'default' style to 'normal'.
+- Updated `--help` option text.
+- 'a2x': The `asciidoc_opts`, `dblatex_opts`, `fop_opts` and
+  `xsltproc_opts` command-line options can be specified multiple
+  times.  This makes embedding multiple 'a2x' options in document
+  headers easier to manage and less error prone.
+- Added ASCIIMathML and LaTeXMathML support to slidy backend.
+- Pass the 'encoding' attribute to the Pygments source highlight
+  filter command.
+- 'a2x': HTML Help `.hhk` file named after AsciiDoc source file.
+- 'a2x': Added `--xsl-file` option to allow custom XSL stylesheets to
+  be specified.
+- Make builds the man pages. Patch submitted by Sebastian Pipping.  See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/c21c2902c29bae64
+
+.Bug fixes
+- *FIXED*: Sometimes double backquotes were misinterpreted as inline
+  literal macros.  See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/f510ea82a88aaee8
+- *FIXED*: Regression in 8.6.2: command-line attributes were not
+  available to the global asciidoc.conf.
+- *FIXED*: Postponed document title substitutions until backend conf
+  files have been loaded (8.6.2 regression). See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/42b63ce90c2563b8
+- *FIXED*: The XSL Stylesheets customizations were preventing chapter
+  and section level TOCs from being generated when using XSL
+  Stylesheets via 'a2x'.  See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/42b63ce90c2563b8
+- *FIXED*: ``UnicodeDecodeError: \'ascii' codec can't decode byte''
+  error.  This error is due to a limitation in the Python HTMLParser
+  module, see: http://bugs.python.org/issue3932
+- *FIXED*: Broken `--no-conf` option (8.6.2 regression).
+- *FIXED*: Regression in 8.6.2: configuration attribute entries set in
+  the document header may cause a 'FAILED: incomplete configuration
+  files' error.
+- *FIXED*: 'html4': corrected self closed meta tags.
+- *FIXED*: 'a2x' regression in 8.6.2: HTML Help `.hhp` file name had
+  reverted to default name instead of the AsciiDoc source file name.
+  See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/dedc961b23e9ac56
+- *FIXED*: Attributes in man page title caused it to be dropped
+  resulting in invalid DocBook output.
+- *FIXED*: `make uninstall` now deletes the `asciidoc.1` and `a2x.1`
+  man pages.
+
+
+Version 8.6.2 (2010-10-03)
+--------------------------
+.Additions and changes
+- 'docbook45': Enclosed bibliographic lists in a 'bibliodiv' -- you
+  can now include block titles with bibliographic lists.
+- Added optional 'keywords', 'description' and 'title' document header
+  meta-data attributes to HTML backends for SEO.
+- AttributeEntry values can span multiple lines with a ' +' line
+  continuation.
+- Added 'slidy' backend (based on Phillip Lord's slidy backend
+  https://phillordbio-asciidoc-fixes.googlecode.com/hg/).
+- Implemented 'OpenBlock' 'partintro' style for book part
+  introductions.
+- Comment lines substitute special characters only.
+- Backend specific global configuration files (all except
+  `asciidoc.conf`) are loaded *after* the header has been parsed --
+  virtually any attribute can now be specified in the document header.
+- 'xhtml11': Volnitsky theme: allow bulleted lists to have intervening
+  children.
+- 'xhtml11': refactored CSS font-family rules to start of file.
+- 'xhtml11': list bullets colored gray.
+- 'ifdef' and 'ifndef' system block macros accept multiple attribute
+  names: multiple names separated by commas are 'ored'; multiple
+  attribute names separated by pluses are 'anded'.
+- 'xhtml11': Volnitsky theme: set max-width on labeled lists.
+- Vim syntax highlighter: Entities inside quoted text are now
+  highlighted.
+- Added 'role' and 'id' attributes to HTML outputs generated by
+  'OpenBlocks'.
+- Allow floating titles to generate 'h1' (level 0) titles in HTML
+  outputs.
+- Added a 'start' attribute to numbered lists to set the start number.
+  See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/c14a4c3b1e4f6dc5
+- Added two more docinfo attributes 'docinfo1' and 'docinfo2' to allow
+  and control inclusion of a shared docinfo file. See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/c948697943432e24
+- Vim syntax highlighter highlights multi-name conditional attributes.
+- LaTeX backend patch submitted by Andreas Hermann Braml (see
+  http://groups.google.com/group/asciidoc/browse_thread/thread/1c415fc4540ce5e5).
+- Implemented 'backend aliases'; renamed `docbook.conf` to
+  `docbook45.conf` and aliased 'docbook45' backend to 'docbook';
+  aliased 'xhtml11' to 'html'.
+
+.Bug fixes
+- *FIXED*: Filter commands located in filter directories local to the
+  source document that where not in the search 'PATH' where not found.
+- *FIXED*: Volnitsky theme: Verseblock font set normal instead of
+  monospaced.
+- *FIXED*: 'xhtml11': Callout icons were not rendered as Data URIs
+  when 'icons' and 'data-uri' attributes were specified.
+- *FIXED*: Long standing bug: nested include macros did not restore
+  the parent document 'infile' and 'indir' attributes. See:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/8712a95e95a292a7
+- *FIXED*: 'html4': set preamble ID anchor.
+- *FIXED*: 'xhtml11': dropped unusable 'id' and 'role' attributes from
+  preamble template.
+- *FIXED*: Bug in multi-name conditional attributes e.g. `{x,y#}`
+  fails if x or y is undefined.
+- *FIXED*: latex filter not being installed by Makefile. Thanks to
+  Grant Edwards for this patch. See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/c4427a3902d130a8
+- *FIXED*: 'a2x': Long-standing bug in a2x which always passes
+  `--string-param navig.graphics 0` to 'xsltproc', regardless of
+  whether icons are enabled or not.  Reported by Michael Wild:
+  http://groups.google.com/group/asciidoc/browse_thread/thread/59a610068e4acb58
+
+
+Version 8.6.1 (2010-08-22)
+--------------------------
+.Additions and changes
+- 'a2x': `--resource-dir` option renamed to `--resource`.
+- 'a2x': `--resource` option accepts both file and directory names.
+- 'a2x': Added `-m,--resource-manifest` option.
+- Added Vim syntax highlighting for quote attribute lists.
+- Load 'asciidoc.conf' from all configuration directories before any
+  other configuration files. This ensures that attributes used for
+  conditional inclusion are set before backend configuration files are
+  processed. Previously if you wanted to control global conf file
+  inclusion your only choice was to modify the global 'asciidoc.conf'
+  file.
+- AsciiDoc 'Quote element' attributes have been simplified and
+  generalized -- positional color and size attributes and named 'role'
+  attribute have been replaced by a single positional attribute.
+
+.Bug fixes
+- *FIXED*: 'testasciidoc.py': `BACKEND` command argument was being
+  ignored.
+- *FIXED*: Broken 'docinfo' file functionality in 'html4' and
+  'xhtml11' backends (previously the docinfo file was included in
+  the 'body' instead of the 'header').
+
+Regression issues
+~~~~~~~~~~~~~~~~~
+This release breaks compatibility with quoted element positional color
+and size attributes (HTML backends). To revert to the deprecated quote
+behavior define the 'deprecated-quotes' attribute in the global
+`asciidoc.conf` file or on the command-line.  For a more detailed
+explanation of the rationale behind this change see
+http://groups.google.com/group/asciidoc/browse_thread/thread/b22603bfb879418c.
+
+
+Version 8.6.0 (2010-08-16)
+--------------------------
+.Additions and changes
+- The AsciiDoc distribution can now be built ``out of the box''
+  from the distribution tarball or the Mercurial repository
+  (provided you have the requisite build applications installed).
+- The global configuration files directory is ignored by both
+  'asciidoc' and 'a2x' if AsciiDoc configuration files are installed
+  in the same directory as the asciidoc executable.  This change
+  allows both a system wide copy and multiple local copies of AsciiDoc
+  to coexist on the same host PC.
+- CSS 'quirks' mode is no longer the default 'xhtml11' output
+  (http://groups.google.com/group/asciidoc/browse_thread/thread/1c02d27d49221aa2).
+- Relaxed anchor ID name syntax
+  (http://groups.google.com/group/asciidoc/browse_thread/thread/5f3e825c74ed30c).
+- Added document files: `doc/epub-notes.txt`,
+  `doc/publishing-ebooks-with-asciidoc.txt`.
+- 'a2x': If all other resource locations are exhausted then recursively
+  search directories named 'images' and 'stylesheets' in the
+  'asciidoc' configuration files directory.
+- 'a2x': options can also be set in the AsciiDoc source file. If the
+  source file contains a line beginning with '// a2x:' then the
+  remainder of the line will be treated as a2x command-line options.
+- Added dblatex table-width processing instruction -- tables generated
+  by dblatex now observe the AsciiDoc table width as a percentage
+  (thanks to Gustav Broberg for suggesting this enhancement).
+- 'a2x': Don't exit if the `--epubcheck` option is set and 'epubcheck'
+  is missing, issue warning and continue.
+- Added a global 'plaintext' attribute for dealing with large amounts
+  of imported text.
+- The author name format has been relaxed, if the the author does not
+  match the formal specification then it is assigned to the
+  'firstname' attribute (previously asciidoc exited with an error
+  message).
+- FAQ and documentation updates.
+- Refactored chunked.xsl and epub.xsl files.
+- Exchanged article.epub for more relevant book.epub on website.
+- Put asciidoc.epub User Guide on website.
+- 'a2x': Chunking EPUB and HTML outputs set to a per chapter basis and
+  the first chapter is separate from preceding contents.
+- Changed dates format in example article and books to suppress EPUB
+  validation error.
+- Added 'style' and 'role' CSS classes to xhtml11 section templates.
+- Added the 'role' element to xhtml11 backend block templates.
+- Suppressed md5 module deprecation warning from music and Graphviz filters.
+- Pygments (https://pygments.org/) option added to source code
+  highlight filter.  Based on Pygments source code filter written by
+  David Hajage
+  (http://groups.google.com/group/asciidoc/browse_thread/thread/d8d042f5a3021369/8934ebbb8cb7144b).
+- xhtml11: Added a new theme (volnitsky). Written and contributed by
+  Leonid V. Volnitsky.
+- xhtml11: Set body element class name to document type.
+- Added refentryinfo element and contents (including revdate) to man
+  page DocBook output. Man pages are now dated using the revdate
+  attribute value if it has been defined.  Based on patch supplied by
+  Rainer Muller
+  http://groups.google.com/group/asciidoc/browse_frm/thread/319e5cd94493e330/3fcb83fab067af42.
+- Added `{template:...}` system attribute.
+- Table of contents attribute 'toc' can now be specified in the
+  document header.
+- Reimplemented music and latex filter -m option functionality when
+  the input is stdin using MD5 checksums.
+- Added 'latex' filter.
+- Added auto file name generation to image generating filters
+  (latex,music, graphviz).
+- Added `counter2` and `set2` system attributes (to implement image
+  auto file name generation).
+- Undefined attribute in filter command generates error but does not
+  exit.
+- Attribute substitution proceeds from start line to end line
+  (previously was in reverse order which was really confusing).
+- Tidied up music filter code:
+  * Format option is optional and default to 'abc' unless Lilypond
+    notation detected.
+  * The -m option does not apply to stdin input.
+- Added paragraph styles to music and graphviz filters.
+- Documented dynamic template names.  753: Graphviz filter can now
+  generate SVG format images. Patch submitted by Elmo Todurov, see:
+  http://groups.google.com/group/asciidoc/browse_frm/thread/fe9b33d8f5f1e0af
+  The xhtml11 SVG Graphviz template marked EXPERIMENTAL. No SVG
+  support for other backends.
+- AsciiDoc template names can now contain embedded attribute
+  references.
+- Added 'legalnotice' tag to `doc/article-docinfo.xml` example.
+- xhtml11 backend: Callouts and callout lists display callout icons
+  when the 'icons' attribute is defined. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/8eda3ea812968854
+- Document attribute names are case insensitive everywhere, this makes using
+attribute entries more consistent e.g. previously :VERS: had to be referred to
+with {vers} ({VERS} did not work).
+- Hungarian translation of footer-text (submitted by Miklos Vajna).
+  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72#
+- asciidocapi.py 0.1.2: Can now load AsciiDoc script named asciidoc.
+  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/66e7b59d12cd2f91
+  Based on patch submitted by Phillip Lord.
+- German translation of footer-text (submitted by Simon Ruderich). See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72
+- Pushed HTML footer text into language conf files with the
+  introduction of a footer-text configuration file template section.
+  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72
+
+.Bug fixes
+- *FIXED*: Sometimes multiple double quoted text elements in the same
+  paragraph were mistakenly seen as starting with an inline literal.
+  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/219c86ae25b79a21
+- *FIXED*: 'localtime' and 'doctime' attributes calculated incorrect
+  daylight saving / non daylight saving timezones and consequently so
+  did HTML footers.  Patch submitted by Slawomir Testowy. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/af652507caf6cec9
+- *FIXED*: Missing selector for 'List of examples' title in DocBook
+  CSS file. Patch submitted by Laurent Laville. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/3f96900f7fbf5620
+- *FIXED*: Broken accents in lang-hu.conf. See:
+  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72
+- *FIXED*: DocBook XSL generated HTML callout lists are properly
+  aligned.  Submitted by Lionel Orry. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/2ff802547b6a75ea
+- *FIXED*: Filter execution now occurs prior to filter markup template
+  substitution to ensure image data URI encoding happens after image
+  generation (see
+  http://groups.google.com/group/asciidoc/browse_thread/thread/14e8fcb289a135b).
+- *FIXED*: The section numbers no longer increment when the 'numbered'
+  attribute is undefined (see
+  http://groups.google.com/group/asciidoc/browse_thread/thread/faa36e9e5c7da019/d24cab3fe363e58d).
+
+
+Version 8.5.3 (2010-01-18)
+--------------------------
+.Additions and changes
+- a2x: Added a2x configuration file options ASCIIDOC_OPTS,
+  DBLATEX_OPTS, FOP_OPTS, XSLTPROC_OPTS (appended to same-named
+  command-line options). See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/ac4b9bfa2116db28
+- Dropped `.hgignore` from the repository. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/c17abd175778f5ea
+- Don't pass verbose options to asciidoc table filter so that
+  asciidocapi messages are not discarded. See:
+  http://groups.google.com/group/asciidoc/browse_frm/thread/c17abd175778f5ea
+- Added `./tests/data/lang-pt-BR-test.txt` file to the repository.
+- xhtml11: Verse block and verse paragraph content enveloped in a
+  'pre' tag (instead of a 'div') so it renders better in text-only
+  browsers. See:
+  http://groups.google.com/group/asciidoc/browse_frm/thread/1b6b66adb24e710
+- User Guide: Clarified Passthrough Blocks (suggested by Simon
+  Ruderich).

+- FAQ errata and updates (submitted by Simon Ruderich).
+- User Guide errata.
+- Simplified 'asciidoc-toc' processing instruction and included lists
+  of figures, tables, examples and equations in books (i.e. revert to
+  pre-8.5.0 behavior).
+- Attempted to have dblatex recognise the 'asciidoc-toc' processing
+  instruction but couldn't get it to work.
+- Added 'notitle' attribute to allow the document title to be hidden.
+
+
+.Bug fixes
+- *FIXED*: Regression: system attribute escaping did not work.
+- *FIXED*: Website: broken image links in chunked User Guide.
+
+
+Version 8.5.2 (2009-12-07)
+--------------------------
+.Additions and changes
+- Updated example article and book documents with the recommended
+  explicit section name syntax (see  the 'Special section titles
+  vs. explicit template names' sidebar in the AsciiDoc 'User Guide').
+- Added Italian language configuration file (contributed by Fabio
+  Inguaggiato).
+- Added 'header' table style. See:
+  http://groups.google.com/group/asciidoc/browse_frm/thread/a23fea28394c8ca9
+- Pass 'icons', 'data-uri', 'imagesdir', 'iconsdir' attributes to
+  'asciidoc' table style filter so that images are rendered in table
+  cells.
+- Pass 'trace' and 'verbose' attributes to 'asciidoc' table style
+  filter so diagnostic information is printed from table cell source.
+- The 'eval' system attribute can be nested inside other system
+  attributes.
+- HTML outputs: Table and figure caption punctuation set to more usual
+  syntax.
+- docbook backend: footnotes can now contain embedded images.  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/50b28f6941de111a
+- CSS tweaks so that tables processed by DocBook XSL Stylesheets have
+  the default asciidoc xhtml11 backend styling.  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/dfe5204d5b2c9685
+- Block titles take precedence over section titles to avoid titled
+  delimited blocks being mistaken for two line section titles (see
+  http://groups.google.com/group/asciidoc/browse_frm/thread/f0b6f9989f828c3).
+- Section title trace displays level and title text.

+- *FIXED*: Absolute 'imagesdir' and 'iconsdir' attribute  path names
+  do not work with the xhtml11 data-uri encoding. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/cb8b7694bbc82a6
+- *FIXED*: Regression issue with inline data-uri images. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/cb8b7694bbc82a6
+- *FIXED*: An unexpected error occurred when processing a table

+
+Version 8.5.1 (2009-10-31)
+--------------------------
+.Additions and changes
+- If an AsciiDoc document file begins with a UTF-8 BOM (byte order
+  mark) then it is passed transparently through to the output file.
+  The BOM is stripped from included files.  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/e5e61823ff4203cd
+- Added AsciiDoc 'role' attribute to quoted text. Sets 'class'
+  attribute in HTML outputs; 'role' attribute in DocBook outputs. See:
+  http://groups.google.com/group/asciidoc/browse_frm/thread/2aa3e5711d243045
+- Conditional attribute syntax extended: they now accept multiple ORed
+  or ANDed attribute names.
+- The 'xhtml11' backend dynamically processes footnotes using
+  JavaScript.
+- Tidied up and namespaced 'xhtml11' JavaScript.
+- Superseded `javascripts/toc.js` with `javascripts/asciidoc-xhtml11.js`.
+- Added 'disable-javascript' attribute ('xhtml11' backend).
+- Styled HTML footnotes.
+- Added links to HTML footnote refs.
+- Added title attribute to inline image macros to display popup
+  ``tooltip'' (HTML outputs only).
+- Single-quoted attribute values are substituted in block macros (just
+  like the AttributeList element).
+- For consistency changed underscores to dashes in attribute names.
+  Public attributes with underscores retained for compatibility.
+- Added Brazilian Portuguese language configuration file (contributed
+  by Thiago Farina).
+- Added 'leveloffset' attribute to make it easier to combine
+  documents.
+
+.Bug fixes
+- *FIXED:* a2x: `--dblatex-opts` is now processed last so
+  `asciidoc-dblatex.xsl` params can be overridden. Patch submitted by
+  Mark Fernandes (see
+  http://groups.google.com/group/asciidoc/browse_frm/thread/5215c99dcc865e7d).
+- *FIXED:* An error occurred if a directory in current path with same
+  name as executable.
+
+Regression issues
+~~~~~~~~~~~~~~~~~
+There's been quite a bit of tiding up to the xhtml11 JavaScript. The
+most obvious change is that the toc.js script has been superseded by
+asciidoc-xhtml11.js so if you're linking you'll need get a copy of
+the new file from the distribution javascripts directory.
+
+If you use customised xhtml11 configuration file `header` and
+`footer` sections and you want them to use the new footnotes feature
+then you've got a bit more work to do:
+
+. The onload event expression changed.
+. The new `<div id="content">...</div>` div envelopes document
+  content.
+. You need to add `<div id="footnotes">...</div>` div to the
+  `footnotes` section for footnotes to work.
+. Drop the `ifdef::toc` macro that surround JavaScript inclusion.
+
+Take a look at the header and footer changes in the xhtml11.conf
+diff to see what's going on:
+http://hg.sharesource.org/asciidoc/diff/55a5999bfd04/xhtml11.conf
+
+
+Version 8.5.0 (2009-10-04)
+--------------------------
+.Additions and changes
+- Implemented a 'float' attribute for tables and block images (HTML
+  outputs only).
+- Added `unfloat::` block macro to cancel floating.
+- Added table 'align' attribute to (HTML outputs only).
+- The image 'align' attribute now works with HTML backends.
+- Renamed table cell 'align' attribute to 'halign' so it doesn't clash
+  with the new table 'align' attribute.
+- Added 'breakable' and 'unbreakable' options to AsciiDoc example and
+  block image elements.
+- `miscellaneous` section entries now update properly when set from
+  a document 'AttributeEntry'.
+- `miscellaneous` section `pagewidth` entry accepts fractional
+  values.
+- Fractional column widths are now calculated correctly when using
+  fractional 'pageunits' (DocBook tables).
+- Use DocBook XSL table width processing instructions.
+- asciidoc 'KeyboardInterrupt' exits with error code 1.
+- Added 'set' system attribute to  allow attributes to be set from
+  configuration file templates.
+- Allow constrained quotes to be bounded on the left by a colons and
+  semicolons, see
+  http://groups.google.com/group/asciidoc/browse_frm/thread/b276a927fdc87995
+- Titled listing and literal blocks (DocBook outputs) no longer default
+  to examples. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/f4df7c9eec01a9bd
+- Updated language file table, figure and example captions to
+  accommodate new auto-numbering in html4 and xhtml11 backends.
+- Titled source highlight filter listings generated by docbook backend
+  are now rendered as examples. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/f4df7c9eec01a9bd
+- Implemented 'counter' system attribute.
+- Use 'counter' system attributes to number titled tables and block
+  images in HTML backends.
+- Added program name suffix to console messages.
+- Added substitution to the 'AttributeEntry' passthrough syntax, this
+  replaces the now unnecessary 'attributeentry-subs' attribute.
+- Allow passthrough inline macro syntax to be used in
+  'AttributeEntrys'.
+- Reinstated 8.4.4 default 'lang' attribute behavior. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/d29924043e21cb6a.
+- Added 'max-width' attribute to the 'xhtml11' backend to set maximum
+  display width. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/74d9a542b79ccd50.
+- Added 'a2x.py', a rewritten and much enhanced version of the old
+  'a2x' bash script.
+- The new 'a2x' can output EPUB formatted documents.
+- Added `--safe` option and deprecated `--unsafe` option. Patch
+  submitted by Todd Zullinger. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/ea3a8ea399ae5d2a
+  and
+  http://groups.google.com/group/asciidoc/browse_frm/thread/69b3183fdab7c6a5
+- Added 'CHECK' and 'TEST' todo highlight words to Vim syntax
+  highlighter.
+- Line breaks, page breaks, and horizontal rulers are now processed by
+  dblatex, thanks to a patch submitted by Mark Fernandes
+  (http://groups.google.com/group/asciidoc/browse_frm/thread/a254cf949ea7c6c5).
+- Allow footnote macros hard up against the preceding word so the
+  rendered footnote mark can be placed against the noted text without
+  an intervening space (patch submitted by Stas Bushuev,
+  http://groups.google.com/group/asciidoc/browse_frm/thread/e1dcb7ee0efc17b5).
+- Normalized path in `safe_filename` function (submitted by Todd
+  Zullinger,
+  http://groups.google.com/group/asciidoc/browse_frm/thread/69b3183fdab7c6a5).
+- The Asciidoc 'numbered' and 'toc' attributes cause DocBook outputs
+  to include `asciidoc-numbered` and `asciidoc-toc` processing
+  instructions, these are used by DocBook XSL to include section
+  numbering and table of contents (like Asciidoc HTML backends). For
+  backward compatibility both 'numbered' and 'toc' attributes are
+  defined by default when the 'docbook' backend is used.  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/1badad21ff9447ac.
+- 'data-uri' attribute is now evaluated dynamically and can be set in
+  document body (previously could only be set from command-line).
+- Added 'sys3' and 'eval3' system attributes to passthrough generated
+  output, this fixes the data-uri inline image problem:
+  http://groups.google.com/group/asciidoc/browse_frm/thread/a42db6bc54c2c537.
+- Missing language file generates a warning instead of an error.
+- Updated Spanish language file (updates contributed by Gustavo Andrés
+  Gómez Farhat).
+
+.Bug fixes
+- *FIXED:* Options in an 'AttributeList' option attribute are merged
+  with (rather than replace) configuration file options.
+- *FIXED:* Comment blocks and comment block macros no longer consume
+  preceding block titles and attribute lists.
+- *FIXED:* `examples/website/layout1.conf` and
+  `examples/website/layout2.conf` TOC problem.  Submitted by Mark
+  (burtoogle).  See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/b9c63be67dd1d11c
+- *FIXED:* Only the first occurrence of passthrough macro was
+  substituted.  Patch submitted by  Peter Johnson. See
+  http://groups.google.com/group/asciidoc/browse_frm/thread/1269dc2feb1a482c
+- *FIXED:* asciidoc now runs on Jython 2.5.0.
+- *FIXED:* Wordpress margins and pads in a number of block
+  elements
+  (http://groups.google.com/group/asciidoc/browse_frm/thread/36ff073c79cbc20a).
+
+Regression issues
+~~~~~~~~~~~~~~~~~
+- Tables generated by 'dblatex' occupy 100% of the available space
+  regardless of the 'width' attribute setting. To restore width
+  behavior change the 'pageunits' miscellaneous parameter to 'pt'. You
+  can do this from the command-line with the `-a pageunits=pt` option.
+  See {website}userguide.html#X89DocBook table widths.
+
+
+Version 8.4.5 (2009-05-24)
+--------------------------
+.Additions and changes
+- Added manpage 'Name' and 'Synopsis' section title customization to languages
+  configuration files.
+- Synopsis manpage section no longer mandatory.
+- Section markup templates can be specified by setting the title's
+  first positional attribute or 'template' attribute.
+- The article and book document header can now include a revision
+  remark.
+- A 'role' attribute can now be applied to block elements. This adds
+  the 'role' attribute to DocBook elements. Patch submitted by
+  http://groups.google.com/group/asciidoc/browse_thread/thread/62278a054188a038Noah
+  Slater).
+- Renamed 'revision' and 'date' attributes to more sensible and consistent
+  'revnumber' and 'revdate' (old names deprecated but still
+  recognized).
+- Moved backend specific attributes to Appendix H in User Guide.
+- Renamed and generalized the docbook backend revision history
+  inclusion mechanism to 'docinfo' to reflect the use of all article
+  or book information elements. The old revision history names still
+  work but have been deprecated.
+- Refactored docbook.conf headers.
+- Moved line break replacement from `replacements` to
+  `replacements2` so the replacement occurs after the mailto macro.
+  This fixes bug
+  http://groups.google.com/group/asciidoc/browse_thread/thread/4bdcdfb0af773e2
+- The typewriter to punctuation apostrophe replacement can be escaped
+  with a backslash.
+- Graphviz filter outputs images to 'imagesdir' if it is defined.
+- Made the block image macro generic so that it can be used for filter
+  outputs. As a result Music and Graphviz filters:
+  * Have been greatly simplified.
+  * Honor the 'data-uri' attribute.
+  * 'html4' outputs no longer generate W3C validation warning.
+- The 'iconsdir' attribute no longer requires a trailing directory
+  separator character.
+- Removed borders around linked html4 images.
+- Added 'html4' specific HTML output for music filter.
+- 'a2x': Added `--unsafe` option (shortcut for
+  `--asciidoc-opts=--unsafe`).
+- 'a2x': The FOP executable can now be named `fop` (this is the
+  default name in some distributions).
+- Attributes are now substituted in the system macro attribute list.
+- If the output is set to stdout (i.e. no output directory is defined)
+  then Music and Graphviz filters will output included images to the
+  source file directory.
+- Added 'name' directive to 'testasciidoc'.
+- Added lots of 'testasciidoc' new tests.
+- Moved language specific configuration parameters into `lang-en.conf`
+  file.
+- 'lang' attribute entry can be specified in the AsciiDoc source file
+  (preceding the header).
+- Removed cruft from A-A-P scripts and documented them.
+- Added German language config file (`lang-de.conf`) contributed by
+  Michael Wild.
+- Added French language config file (`lang-fr.conf`) contributed by
+  Yves-Alexis Perez.
+- Added Russian language config file (`lang-ru.conf`) contributed by
+  Artem Zolochevskiy.
+- Added Hungarian language config file (`lang-hu.conf`) contributed by
+  Miklos Vajna.
+
+.Bug fixes
+- *FIXED:* Multiple manpage names are now handled correctly when
+  generating DocBook output, each name now generates a separate
+  DocBook `<refname>` element. See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/c93bb4db025225d8
+- *FIXED:* A problem that caused AttributeEntries preceding the header
+  to be overwritten when the language conf file loaded.
+- *FIXED:* Possible inline macro name ambiguity e.g. link matches olink.
+- *FIXED:* The documented macro definition deletion behavior had been
+  broken for a long time.
+- *FIXED:* Email addresses not recognized when followed by a period
+  character.
+- *FIXED:* Hyphens in mailto macros can delimit nested addresses e.g.
+  \bloggs@mail was processed inside
+  \mailto:joe-bloggs@mail-server.comMail.
+- *FIXED:* User name in FTP URI generated incorrect FTP link. See
+  http://groups.google.com/group/asciidoc/browse_thread/thread/1d796a9c9ddb2855
+- *FIXED:* Source highlighter now works with Wordpress backend (see
+  http://groups.google.com/group/asciidoc/browse_thread/thread/6d8c716748b109e3).
+
+X2
+Regression issues
+~~~~~~~~~~~~~~~~~
+. A colon following the date in the AsciiDoc header is treated as a
+  revision remark delimiter -- this could be an issue if you have used
+  a colon in the header date.
+
+
+Version 8.4.4 (2009-04-26)
+--------------------------
+.Additions and changes
+- Added table column and row spanning.
+- Table styles can now be applied per cell.
+- Vertical cell alignment can be applied to columns and individual
+  cells.
+- Added table 'align' attribute to set horizontal alignment for entire
+  table.
+- Included Geoff Eddy's update of the experimental LaTeX backend.
+- A new attribute named 'trace' controls the output of diagnostic
+  information. If the 'trace' attribute is defined then
+  element-by-element diagnostic messages detailing output markup
+  generation are printed to stderr.
+- Added 'literal' paragraph style (allows 'literal' style to be
+  applied to normal paragraphs).
+- Deleted unused `replacements2` from `xhtml11.conf`.
+- Added `replacements2` to default substitutions.
+- 'testasciidoc.py': messages to 'stdout', only diffs to 'stderr'.
+- Added transparency to `smallnew.png` image.
+
+.Bug fixes
+- All combinations of leading comments and attribute entries at the
+  start of a document are now skipped correctly.
+- *FIXED:* `./configure` doesn't support `--docdir` as expected (patch
+  submitted by Artem Zolochevskiy)
+- *FIXED:* Constrained quotes were incorrectly matched across line
+  boundaries e.g. the string `+\nabc+` incorrectly matched a monospace
+  quote.
+
+
+Version 8.4.3 (2009-04-13)
+--------------------------
+.Additions and changes
+- DocBook outputs default to DocBook version 4.5 doctype (previously
+  4.2).
+- Configuration file `specialsections` definitions can be undefined
+  by setting their configuration entry values blank.
+- The Makefile 'install' target depends on the 'all' target to ensure
+  pre-install patches are applied.
+- 'testasciidoc.py' now emits user friendly messages if:
+  . the configuration file is missing.
+  . an illegal backend is specified.
+  . an illegal test number is specified.
+
+.Bug fixes
+- Fixed
+  http://groups.google.com/group/asciidoc/browse_thread/thread/fd27add515597c06missing
+  template section error.
+- The 'testasciidoc.py' `--force` option no longer deletes test data
+  files that were not specified.
+- Dropped second quotes substitution in table cells -- it had
+  effectively disabled quote escaping in table cells.
+
+
+Version 8.4.2 (2009-03-19)
+--------------------------
+.Additions and changes
+- Added {website}testasciidoc.htmltestasciidoc, a tool to verify
+  AsciiDoc conformance.
+- A warning is issued if nested inline passthroughs are encountered.
+- 'asciidocapi': setting an attribute value to `None` will undefine
+  (delete) the attribute (this in addition to the `name!` attribute
+  name format that the `asciidoc(1)` command uses).
+
+.Bug fixes
+
+
+Version 8.4.1 (2009-03-10)
+--------------------------
+.Additions and changes
+- AsciiDoc now has a {website}asciidocapi.htmlPython API.  The
+  following minimal example compiles `mydoc.txt` to `mydoc.html`:
++
+source,python
+-------------------------------------------------------------------------------
+from asciidocapi import AsciiDocAPI asciidoc = AsciiDocAPI()
+asciidoc.execute('mydoc.txt')
+-------------------------------------------------------------------------------
+
+- Backtick quoting for monospaced text is now implemented as an
+  'inline literal' passthrough.  This makes more sense since monospace
+  text is usually intended to be rendered literally. See
+  <<X2,Regression issues>> below for the impact this may have on
+  existing documents.  Here are some examples that would previously
+  have had to be escaped:
+
+  The `++i` and `++j` auto-increments.
+  Paths `~/.vim` and `~/docs`.
+  The `__init__` method.
+  The `{id}` attribute.
+
+- Added `--doctest` option to `asciidoc(1)` command.
+- Added an optional second argument to 'BlockId' element, this sets
+  the `{reftext}` attribute which in turn is used to set the `xreflabel`
+  attribute in DocBook elements.
+- Added lists to `--help` syntax summary.
+- `{infile}` and `{indir}` attributes reflect the current input file
+  (previously always referred to the root document).
+- `{docfile}` (new) and `{docdir}` (previously deprecated) attributes
+  refer to the root document specified on the `asciidoc(1)`
+  command-line.
+- Vim syntax highlighter improvements.
+- Syntax summary command (`asciidoc -h syntax`) additions.
+- Admonition icons now have transparent backgrounds.
+- Changed yellow W3C badges to blue ones in page footers.
+
+.Bug fixes
+- Dropped `asciidoc(1)` broken undocumented `--profile` option.
+- Em dash replacement now recognized at start of block.
+
+Regression issues
+~~~~~~~~~~~~~~~~~
+Replacing backtick quoting with the 'inline literal' passthrough
+raises two regression scenarios for existing documents:
+
+1. You have escaped the expansion of enclosed inline elements, for
+   example: `\{id}`.  You would need to delete the backslashes: `{id}`
+   (if you don't the backslashes will be printed). Mostly it's just a
+   case of interactively finding and replacing of all occurrences of
+   `\.
+
+2. There are enclosed inline elements, for example: `some *bold*
+   monospaced`.  You would need to switch to plus character monospace
+   quoting: `+some *bold* monospaced+` (if you don't the enclosed
+   elements won't be expanded).
+
+If your existing documents include these cases and you don't want to
+upgrade then use the `-a no-inline-literal` command-line option,
+alternatively put this in `~/.asciidoc/asciidoc.conf`:
+
+  attributes
+  no-inline-literal=
+
+
+Version 8.3.5 (2009-02-02)
+--------------------------
+.Additions and changes
+- Cached compiled regular expression delimiters (speed up 'User
+  Manual' compilation by 250%).
+- Created distinct list definitions for each numbered list style to
+  allow nesting of all styles.
+- Roman numbers in numbered lists are followed by a closing
+  parenthesis instead of a period to eliminate 'i', 'v', 'x' item
+  ambiguity with respect to alpha numbered list items.
+- Added `**`, `***`, `****`, `*****`
+  bulleted lists.
+- Added `...`, `....`, `.....` implicit numbered
+  lists.
+- Added `:::`, `::::` labeled lists.
+- Updated User Guide for new list syntaxes.
+- Optimized paragraph and list termination detection with separate
+  precompiled regular expressions for performance and to prevent
+  reaching Python 100 named group limit.
+- Updated Vim syntax highlighter for new list syntaxes.
+- Allow `template::` macros in conf file entries sections (not just
+  in template sections).
+- Dropped unused `listdef-numbered2` conf file sections.
+- Renamed 'ListBlock' to more appropriate 'OpenBlock'.
+- Implemented single-line versions of `ifdef::` and `ifndef::`
+  macros.
+- 'html4' backend styling:
+  * Underlined admonition captions.
+  * Added side border to Example Blocks.
+- 'xhtml11' backend styling:
+  * Dropped right hand margin from all but quote and verse blocks.
+  * html4 backend: corrected over-sized width of caption in admonition
+    block.
+
+.Bug fixes
+- Fixed broken numbered list nesting.
+
+Compatibility issues
+~~~~~~~~~~~~~~~~~~~~
+The roman numbered list parenthesis syntax is incompatible with the
+potentially ambiguous roman period syntax introduced in 8.3.2.
+
+
+Version 8.3.4 (2009-01-20)
+--------------------------
+.Additions and changes
+- Implemented a title 'float' style.  A floating title (or bridgehead)
+  is rendered just like a normal section but is not formally
+  associated with a text body and is not part of the regular section
+  hierarchy so the normal ordering rules do not apply.
+- Implemented inline comment macro so comment lines can now appear
+  inside block elements.
+- Comment lines are sent to the output if the 'showcomments' attribute
+  is defined (comment blocks are never sent to the output).
+- Single quoting attribute values in 'AttributeList' elements causes
+  them to be substituted like normal inline text (without single
+  quoting only attribute substitution is performed).
+- Rewrote list item processing (was very crufty). List continuation
+  and list blocks now work as expected. Updated and clarified list
+  documentation in User Guide.
+- The 'revision' attribute now recognizes the RCS $Id$ marker format.
+- An RCS $Id$ marker formatted revision line in the header does not
+  need to be preceded by an author line.
+- If an RCS $Id$ formatted revision is specified and the author name
+  has not already been set then the author name in the $Id$ marker
+  will be used.
+- Updated Gouichi Iisaka's Graphviz filter to version 1.1.3.
+- Added 'autowidth' table attribute option for (X)HTML outputs.
+- DocBook backend now puts 'orgname' optional attribute in DocBook
+  header.
+- Deprecated undocumented 'companyname' attribute in favor of
+  DocBook's 'corpname'.
+- Removed explicit closing backslash from HTML4 self-closing tags to
+  comply with WC3 recommendation.
+
+.Bug fixes
+- Fixed 8.3.3 regression whereby adjacent lists with the same syntax
+  but different list styles were incorrectly treated as a single list.
+
+
+Version 8.3.3 (2009-01-02)
+--------------------------
+This release supersedes 8.3.2.
+
+.Bug fixes
+- The broken and confusing numeration and numeration2 numbered list
+  attributes have been dropped, use the style attribute instead.
+
+
+Version 8.3.2 (2009-01-01)
+--------------------------
+.Additions and changes
+- Added Gouichi Iisaka's Graphviz filter to distribution.
+- The 'SidebarBlock' element can now be rendered with an 'abstract'
+  style.
+- Reorganized filters into a separate subdirectory for each filter.
+- Updated `Makefile.in` and `MANIFEST` files to reflect new filters
+  organization.
+- Added 'listing' style to 'LiteralBlock' element so listings with
+  nested listing blocks can be rendered as a listing block.
+- Changed example 'code' filter to use preferred 'ListingBlock' syntax
+  (the old `~` delimited filter syntax is no longer used).
+- Implemented 'enumeration' and 'enumeration2' numbered list
+  attributes for specifying the list numbering style ('arabic',
+  'loweralpha', 'upperalpha', 'lowerroman' and 'upperroman').
+- AsciiDoc now recognizes 'upperalpha', 'lowerroman' and 'upperroman'
+  numbers in `listdef-numbered2` numbered lists and sets the number
+  style based on the style of the first numbered list item
+  (alternative to setting 'enumeration2' attribute).
+- Updated `formatlistpat` definition in `.vimrc` example in User
+  Guide.
+- You can now backslash escape system block macros.
+- Added 'Pychart' FAQ.
+- Drop paragraph 'text' and list 'text', 'index' and 'label' match
+  groups from attributes -- they are included in the element's text
+  and we don't want them processed a second time as attributes.
+- Changed comment line block macro to a passthrough block macro to
+  ensure no substitutions.
+- A 'subslist' no longer has to be appended to a 'PassthroughBlock'
+  macro definition, if omitted no substitutions are performed.
+- Code tidy up: replaced deprecated `<>` operator with `!=`.
+- Removed unused linuxdoc code.
+- Code tidy ups: dropped old types module reference; replaced
+  `has_key()` with preferred `in` operator.
+
+.Bug fixes
+- Old syntax source highlight filter regression: special characters
+  where not escaped in DocBook outputs.
+
+
+Version 8.3.1 (2008-12-14)
+--------------------------
+.Additions and changes
+- Replaced the `install.sh` script with Ben Walton's updated autoconf
+  scripts -- see {website}INSTALL.htmlINSTALL for details.
+- Added a generalized 'AttributeEntry' syntax to allow arbitrary
+  configuration file entries to be set from within an AsciiDoc
+  document (suggested by Henrik Maier).
+- Listing delimited blocks in DocBook outputs now support IDs; IDs of
+  titled Listing and Literal delimited blocks have been moved to the
+  enclosing DocBook example tag (thanks to Vijay Kumar for this
+  patch).
+- Replaced vertical typewriter apostrophe with punctuation apostrophe
+  (thanks to Noah Slater).
+
+.Bug fixes
+- Regression: Excluding double-quotes from unquoted attribute values
+  resulted in backward incompatibility, double-quotes in unquoted
+  attribute values has been reinstated.
+- Regression: Text like `&...;` was sometimes mistaken for an entity
+  reference -- tightened up entity reference matching.
+
+
+Version 8.3.0 (2008-11-29)
+--------------------------
+.Additions and changes
+- {website}newtables.htmlAsciiDoc new tables is a complete redesign
+  of the tables syntax and generation. The new syntax and features are
+  a huge improvement over the old tables. The old tables syntax has
+  been deprecated but is currently still processed.
+- {website}newlists.htmlLists can now be styled like other block
+  elements. This allows a single list syntax for 'glossary', 'qanda'
+  (Question and Answer) and 'bibliography' lists instead of having to
+  remember a different syntax for each type.
+- Inline passthroughs macros have been improved and block passthrough
+  macros added. Attribute substitution can be optionally specified
+  when the macro is called.
+- The passthrough block has a fully transparent passthrough delimited
+  block block style called 'pass'.
+- The 'asciimath' and 'latexmath'
+  {website}userguide.html#X77passthrough macros along with
+  'asciimath' and 'latexmath' {website}userguide.html#X76passthrough
+  blocks provide a (backend dependent) mechanism for rendering
+  mathematical formulas. There are {website}latexmath.pdfLaTeX Math,
+  {website}asciimathml.htmlAsciiMathML and
+  {website}latexmathml.htmlLaTeXMathML examples on the AsciiDoc
+  website.
+- Reimplemented and cleaned up filter processing based on a patch
+  submitted by Kelly Anderson.  Uses the newer subprocess module
+  instead of the deprecated popen2 module.  Now works in Win32 command
+  shell.
+- Addition FAQs, more documentation updates.
+- Arbitrary HTML/XML entities can be entered in AsciiDoc source.
+- Did away with the need for the `shaded-literallayout.patch` (thanks
+  to Henrik Maier for this patch).
+- Implemented 'page break' block macro.
+- Added 'line breaks' and 'ruler' processing instructions to DocBook
+  outputs  (thanks to Henrik Maier for this patch).
+- Added 'deg' (degree) and 'wj' (word joiner) entity attributes
+  (thanks to Henrik Maier).
+- Tweaked DocBook 'indexterm2' macro to avoid white space preceding
+  the term when used in table cells (thanks to Henrik Maier for this
+  patch).
+- Title elements now process the 'options' attribute like other block
+  elements.
+- Added `single quoted' element.
+- Spaces on both sides of a -- em-dash are translated to thin space
+  characters.
+- Improved detection and reporting of malformed attribute lists.
+- The list 'compact' style is now a list option.
+- Added 'strong' labeled list option which makes the labels bold (HTML
+  outputs only).
+- Dropped unsupported 'linuxdoc' backend.
+- Dropped deprecated 'xhtml-deprecated' (version 6) backend.
+- Added 'breakable' and 'unbreakable' attribute options to tables to
+  control table breaking across page boundaries (DocBook XSL/FO
+  outputs). By and in collaboration with Henrik Maier.
+- Added 'pgwide' attribute option to tables to table, block image,
+  horizontal labeled lists.  Specifies that the element should be
+  rendered across the full text width of the page irrespective of the
+  current indentation (DocBook XSL/FO outputs). Thanks to Henrik Maier
+  for this patch.
+- Vim syntax highlighter: spaces before/after bullets no longer
+  highlighted (which is ugly if using a theme that highlights with
+  underlines).  Thanks to Donald Chai for this patch.
+- Added `a2x(1)` `--fop` option.
+- Added `a2x(1)` `--no-xmllint` option.
+- Highlighted labelled list terms with the navy color in XHTML

+  just the leading quote.
+- Fixed bug that was causing false negative safe mode warnings (patch
+  submitted by Julien Palmas).
+- Placed priority of AttributeEntry, AttributeList and BlockTitle

+  BlockTitle followed by a same length leading ListingBlock delimiter
+  is not mistaken for a two-line title.
+- Vim syntax highlighter: fixed multi-line quoted text.
+- Contstrained quote termination after non-space character enforced.
+- Vim syntax highlighter: unterminated quoted text is no longer
+  highlighted.

+  styles (creeping featurism, use 'pass' macros instead).
+- Generic 'tag' inline macro (creeping featurism, use 'pass' macros
+  instead).
+
+
+X1
+Compatibility issues
+~~~~~~~~~~~~~~~~~~~~
+Version 8.3.0 has a number of backward incompatibilities with respect
+to the previous 8.2.7 release:
+
+- The old table syntax is still processed but a 'DEPRECATED' warning
+  is issued.
+- Entity references have to be escaped with a backslash.
+- You have to explicitly precede horizontal style labeled lists with
+  the `horizontal` style attribute -- by default all labeled lists
+  are rendered vertically.
+- The list 'compact' style has been dropped and is now a list option
+  (use `options="compact"` in attribute lists).
+- AsciiDoc version 6 syntax no longer supported.
+- Linuxdoc been removed from the distribution.
+- The unsupported experimental 'latex' backend has not been tested on
+  this release.
+- The introduction of single-quote quoting requires that double-quote
+  quoting is escaped with two backslashes.
+
+
+Version 8.2.7 (2008-07-04)
+--------------------------
+.Additions and changes
+- Added `dvi`, `ps` and `tex` output format options to a2x(1).
+- Added `--dblatex` option to a2x(1) so `dblatex(1)` can be used to
+  generate PDFs.
+- Added custom `dblatex(1)` configuration files (in distribution
+  `./dblatex` directory) that are used by a2x(1).
+- `dblatex(1)` is now used to generate the distributed PDF version of
+  the AsciiDoc User Guide.
+- If you don't need a customized the link caption you can enter the
+  'http', 'https', 'ftp', 'file' URLs and email addresses without any
+  special macro syntax -- you get the links by just cutting and
+  pasting URLs and emails addresses. This also makes it easier to open
+  links directly form AsciiDoc source ( most editors allow you to open
+  URLs directly).  The Vim syntax highlighter has been updated to
+  reflect these changes.
+- Highlighted source code paragraphs have been implemented -- it's a
+  much more convenient way to enter short code examples (see
+  http://asciidoc.org/source-highlight-filter.htmlthe
+  online docs).
+- The source highlighter and music filter syntax has changed -- they
+  now used the ListingBlock syntax customized with 'source' and
+  'music' style attribute values. This follows the Paragraph styling
+  convention introduced by the source paragraph (previous item) and is
+  easier to read. The old syntax still works but has been deprecated.
+- QuoteBlocks now have a 'verse' style -- you no longer have to nest a
+  'verse' LiteralBlock inside a QuoteBlock for verses.  The 'verse'
+  style on the LiteralBlock has been deprecated (still works though)
+  and the 'style' attribute is positional attribute 1, pushing
+  'attribution' and 'citetitle' attributes to the right (you'll need
+  to insert a 'quote' attribute into your existing QuoteBlocks).
+- It is no up to the DocBook processor to highlight source code syntax
+  in `<programlisting>` elements rather than GNU Highlighter -- this
+  is the correct way to handle it, plus `dblatex(1)` makes a much
+  better job.
+- 'scaledwidth' and 'align' attributes have been added to the 'image'
+  macro. They apply to DocBook outputs (specifically for PDF
+  documents). 'scaledwidth' sets the image size as a percent of the
+  available page width; 'align' applies 'left', 'center' or 'right'
+  horizontal image justification.
+- Added a2x(1) `--fop-opts=FOP_OPTS` option (patch submitted by Miklos
+  Vajna).
+- Added a2x(1) `--dblatex-opts=DBLATEX_OPTS` option.
+- Added Mikhail Yakshin's FOP 0.95 patch which fixes a long-standing
+  `fo.xsl` problem and allows PDF's to be generated with FOP 0.95
+  (previously had to use FOP 0.20.5).
+- The User Guide has been updated and outdated FOP configuration and
+  installation sections removed.
+
+.Bug fixes
+- Fixed `stylesheets/xhtml11-manpage.css` not being included when
+  'linkcss' attribute was used.
+- Configuration file `*-style` attributes are now dumped correctly.
+- Fixed 'FAILED: malformed section entry' LaTeX backend error.
+
+See the also the https://sharesource.org/hg/asciidoc/AsciiDoc
+repository changelog.
+
+
+Version 8.2.6 (2008-04-29)
+--------------------------
+.Additions and changes
+- Enhancements to the Vim AsciiDoc syntax highlighter, for example,
+  quoted text is now highlighted in titles and macro captions.
+- If you define the `data-uri` intrinsic attribute images referenced
+  by 'image' macros will be embedded in XHTML using the
+  http://en.wikipedia.org/wiki/Data:_URI_schemedata: URI scheme.
+  *NOTE*: Microsoft browser support for the 'data: URI scheme' is
+  currently limited to MSIE 8 beta 1.
+- Added `toc-title` attribute to allow custom table of contents
+  titles.
+- Added references to Alex Efros's AsciiDoc Cheatsheet to AsciiDoc
+  website.
+- `asciidoc(1)` and `a2x(1)` man pages formatted to conform to
+  `man-pages(7)` recommendations.
+- Old code-filter syntax (pre-8.1.0) is no longer recognized so that
+  malformed two-line level 2 titles are no longer confused with
+  'code-filter' block delimiters.
+- Added -> <- => <= arrow replacements from the Arrows block of
+  Unicode.
+- Added DocBook refentry lang attribute -- patch contributed by
+  VMiklos.
+- AttributeEntry names can now be numeric (``named macro targets'').
+- Hide Table of Contents title if Table of Contents empty -- patch
+  contributed by Alex Efros.
+- Various XHTML CSS tweaks.
+- Code cleanup:
+  * Replaced `realpath()` with Python 2.2 `os.path.realpath()` library
+    function.
+  * Replaced old string library functions with string methods.
+  * Use file generators instead of `readlines()`.
+  * Renamed entities that shadowed builtins.
+  * Standardized string quoting.
+  * Dropped `readlines()` function.
+
+.Bug fixes
+- Fixed broken CSS for decimal ordered lists nested in alpha ordered
+  list, thanks to Alex Efros.
+- A missing closing block delimiter now reports the opening delimiter
+  line number instead of the end of file line number.
+- Fixed an error generated by the asciidoc `-e` option when there are
+  no block definitions -- patch contributed by Alejandro Mery.
+- Handle both `\r\n` (as well as `\n`) line separators that may be
+  returned by `{sys}` attribute evaluation.
+- Numbered attribute names no longer interfere with positional
+  attribute list values.
+
+
+Version 8.2.5 (2007-11-18)
+--------------------------
+.Additions and changes
+
+.Bug fixes
+- Fixed exception thrown by illegal command-line arguments.
+- Rolled back the 'with' warning bug fix introduced in 8.2.4 -- it was
+  incompatible with Python <2.5.
+
+
+Version 8.2.4 (2007-11-10)
+--------------------------
+.Additions and changes
+- You can now use the `lang` attribute to set the DocBook language
+  attribute.
+- Attribute values can now contain attribute references.
+- If the `lang` attribute is defined then configuration files named
+  like `lang-<lang>.conf` will be loaded automatically.
+- The help file name `help-<lang>.conf` is based on the AsciiDoc
+  `lang` attribute, defaults to `help.conf` (English).
+- Admonition, figure and table captions have been factored into a
+  predefined set of `caption_*` attributes.  They only apply to
+  directly generated (X)HTML outputs (DocBook stylesheets generate
+  their own language specific captions based on the `lang` attribute).
+- Dropped platform dependent `doc/asciidoc.chm` file from
+  distribution documentation formats.
+
+.Bug fixes
+- The spurious warning 'with will become a reserved keyword
+  in Python 2.6' has been suppressed.
+
+
+Version 8.2.3 (2007-09-12)
+--------------------------
+.Additions and changes
+- Added VMiklos's 'permalink' patch for auto-generated section IDs
+  (enabled by default by the `sectids` attribute).
+- Added http://asciidoc.org/faq.htmlFAQ to website.
+- Changed format of \{localdate} attribute to ISO 8601 (`%Y-%m-%d`).
+- Added `abc2ly --beams=None` option to make `music2png.py` conform to
+  ABC's notion of beams.
+- XHTML level 2 section headings are now styled with an underlining
+  border.
+- XHTML links to AsciiDoc title elements are now implemented with
+  title ID attributes (previously separate `<a>` element targets were
+  generated.
+- Multi-word first, middle and last names can be entered in the header
+  author line using the underscore as a word separator.
+- The nested inline macros restriction has now been lifted, for
+  example you can now include links and inline images inside
+  footnotes.
+- Help topic names can be shortened (so long as they are not
+  ambiguous). For example `asciidoc -hm` will print the AsciiDoc man
+  page.
+- Added `{two_colons}` and `{two_semicolons}` attributes for
+  escaping labeled list ambiguity.
+- If quirks mode is disabled the XHTML Mime Type is set to the
+  recommended `application/xhtml+xml` (rather than `text/html`).
+
+.Bug fixes
+- Author information is now correctly set when using attribute entries
+  in the header instead of an author line (previously the 'author'
+  attribute was not being calculated correctly and there were
+  attribute substitution problems).
+
+
+Version 8.2.2 (2007-07-22)
+--------------------------
+.Additions and changes
+- http://www.maths.nottingham.ac.uk/personal/drw/lm.htmlLaTeXMathML
+  capability has been added for users who are more familiar with or
+  prefer LaTeX math formulas to the
+  http://asciidoc.org/asciimathml.htmlASCIIMathML
+  notation (thanks to Arthur Sakellariou for the patch).
+- The 'source highlight' and 'code' filters now process embedded
+  callouts.
+- Added an `--attribute=ATTRIBUTE` option to `a2x(1)` for passing
+  attribute values to asciidoc(1) (a shortcut for `--asciidoc-opts="-a
+  ATTRIBUTE"`).
+- Image block and inline macros prepend optional `{imagesdir}`
+  attribute to image link targets.
+
+
+.Bug fixes
+- Fixed an assertion error that occurred when a configuration file
+  containing an `include::` macro was loaded using the
+  `--conf-file` option and the configuration file name did not
+  include an explicit directory path -- patch submitted by Dmitry
+  Potapov.
+- Asciidoc titles are only converted to lower case if all characters
+  are upper case otherwise case is left unchanged -- patch submitted
+  by Dmitry Potapov.
+- Added a missing check that input is not stdin before loading
+  configuration files from the document directory -- patch submitted
+  by Dmitry Potapov.
+- Attribute list items must evaluate to strings, numbers or None
+  (previously it was possible to evaluate to other object types which
+  resulted in surprising attribute values).
+- If an AsciiDoc document has no title an empty XHTML 1.1 'title'
+  element is created -- previously the 'title' element was dropped
+  which resulted in invalid XHTML 1.1.
+- The Vim syntax file no longer highlights escaped callouts.
+- The Vim syntax highlighter now correctly highlights Double-dollar
+  passthroughs when they enclose dollar delimited ASCIIMathML and
+  LaTeXMathML formulas.
+
+
+Version 8.2.1 (2007-04-06)
+--------------------------
+.Additions and changes
+- A number of improvements have been made to the Vim syntax
+  highlighter, for example the word C++ is no longer mistaken for the
+  start of an unconstrained monospace quote.
+- Labeled list definitions have been tightened -- a list label can no
+  longer containing trailing spaces. The following example is no
+  longer recognized as a valid list label:
+
+  Lorum ipsum ::
++
+This change implements the originally intended behavior (as per the
+AsciiDoc documentation and examples) so there should be very few
+compatibility issues.
+
+.Bug fixes
+
+
+Version 8.2.0 (2007-04-04)
+--------------------------
+.Additions and changes
+- A Vim syntax file is now included in the AsciiDoc distribution
+  (inspired by Felix Obenhuber's `asciidoc.vim` script). You can find
+  it (along with a Vim filetype detection script in the distribution
+  `./vim/` directory (the scripts are installed automatically by the
+  AsciiDoc installer `./install.sh`). See 'Appendix J' of the
+  'AsciiDoc User Guide' for details.
+- Added 'toclevel' attribute (1..4) which sets the number of title
+  levels reported in the table of contents.  Defaults to 2 and must be
+  used with the 'toc' attribute. Example usage:
+
+  $ asciidoc -a toc -a toclevels=3 doc/asciidoc.txt
+
+- Added a `listindex` attribute which is the current list item index
+  (1..). If this attribute appears outside a list its value is the
+  number of items in the most recently closed list.
+- The single line titles syntax now accepts trailing suffixes -- this
+  syntax matches the title line syntax of a number of popular Wiki
+  markups.
+- If a QuoteBlock has no attribution or citetitle then the DocBook
+  `<attribution>` element is not generated (previously generated empty
+  `<attribution>` element).
+- If the text of a labeled list item is blank then no `texttag` is
+  written.
+- An end of line backslash performs line continuation for horizontal
+  labeled list items.
+- The Revision line now accommodates Subversion `$Id` markers (in
+  addition to CVS and RCS markers). Thanks to Tiago Sturmer Daitx for
+  this patch.
+- Implemented `a2x(1)` option `--skip-asciidoc` which allows `a2x(1)`
+  to convert DocBook XML files not derived from AsciiDoc sources.
+- If `a2x(1) --doctype` option is not specified it defaults to
+  `manpage` if `--format=manpage` else defaults to `article`
+  (previously `--doctype` always defaulted to `article`).
+- Added an 'External Resources' section to the
+  http://asciidoc.org/index.htmlAsciiDoc home page.
+
+.Bug fixes
+
+
+Version 8.1.0 (2006-10-22)
+--------------------------
+.Additions and changes
+- AsciiDoc generated XHTML documents now display a table of contents
+  if the 'toc' attribute is defined (JavaScript needs to be enabled
+  for this to work).  Thanks to Troy Hanson who contributed this
+  feature based on a JavaScript by Mihai Bazon. I've simplified things
+  somewhat to match Docbook XSL Stylesheets style, see Troy's
+  http://tpl.sourceforge.net/userguide.htmltpl User Guide for a
+  fancier layout. Use the `-a toc -a numbered` command-line options to
+  produce a number table of contents.
+- A http://asciidoc.org/music-filter.htmlmusic filter
+  is included in the distribution `./filters/` directory.  It
+  translates music in http://lilypond.org/LilyPond or
+  http://abcnotation.org.uk/ABC notation to standard classical
+  notation in the form of a trimmed PNG image which is inserted into
+  the AsciiDoc output document.
+- Incorporated Paul Melis's Win32 filter patch.  This workaround
+  allows AsciiDoc to run filters under Windows.
+- Added `uninstall.sh` script.
+- Rather than proliferate a confusing number of filter block
+  delimiters the following convention has been adopted: delimiters
+  belonging to DelimitedBlock filters distributed with AsciiDoc will
+  consist of a word (normally a noun identifying the block content)
+  followed by four or more tilde characters.  This has necessitated
+  changing existing filter delimiters (the old delimiters still work
+  but may be deprecated in future versions):
+
+  * The example code filter block delimiter is now the word `code`
+    followed by four or more tilde characters.
+  * The source highlight filter block delimiter is now the word
+    `source` followed by four or more tilde characters.
+
+- Conditionally redefined subscript and superscripting so they use the
+  old replacements mechanism when asciidoc7compatible is defined
+  rather than the asciidoc 8 default unconstrained quoting (patch for
+  affected files attached).
+- Moved the source highlight filter from `./examples/` to `./filter/`.
+- Added `{verbose}` intrinsic attribute (useful for passing verbose
+  flag to filters).
+- Added `{outdir}` intrinsic attribute.
+- Renamed `{docdir}` intrinsic attribute to unambiguous `{indir}`
+  (`{docdir}` still works but may be removed in future release).
+- If `asciidoc(1)` outputs to stdout then intrinsic attribute
+  `{docname}` is extracted from the input file name.
+
+
+Version 8.0.0 (2006-08-27)
+--------------------------
+*********************************************************************
+This is a major release because changes to quoting and index entry
+handling may break existing documents (see 'Additions and changes'
+below and 'Appendix A: Migration Notes' in the AsciiDoc User Guide).
+
+Please report any problems you encounter.
+
+mailto:srackham@gmail.com'Stuart Rackham'
+*********************************************************************
+
+.Additions and changes
+- Quoting can can occur within words (based on patch submitted by
+  Benjamin Klum). See the 'Unconstrained Quotes' sub-section in the
+  User Guide.
+
+- The underline and plus characters can be used as alternatives to the
+  existing apostrophe and backtick quote characters. They are arguably
+  better choices than the apostrophe and backtick as they are not
+  confused with punctuation.
+
+- The syntax for index entry macros have have been deprecated from
+  `+...+` and `++...++` to `((...))` and `(((...)))` respectively.
+  Rationale:
+  * Bracketing is consistent other with `...` and `<<...>>`
+    reference macros.
+  * To easily confused with triple plus passthroughs.
+  * To make way for the new monospace quoting.
+
+- Superscripts and subscripts are implemented as constrained quotes so
+  they can now be escaped with a leading backslash and prefixed with
+  with an attribute list.
+
+- An experimental LaTeX backend has been written by Benjamin Klum (a
+  number additions in this release are to accommodate the LaTeX
+  backend).
+- `include` macro file names now expand environment variables and
+  tilde expansions.
+- A configuration file `quotes` entry can be undefined by setting to
+  a blank value.
+- Added `callto` inline macro for Skype 'callto' links.
+- Added `colnumber` attribute for table data markup.
+- A leading comment block or comment lines are now skipped (previously
+  a document had to start with either attribute entries or a document
+  Title).
+- Experimental `rows` attribute (number of source lines in table)
+  available in table markup templates (used by experimental LaTeX
+  backend).
+- Included install shell script written by mailto:jlm@ofb.netJacob
+  Mandelson for installing the tarball distribution.
+- Added INSTALL documentation file.
+- Added 'replacements2' substitution options -- a second replacements
+  section.
+- Added the ability to redefine 'normal' and 'verbatim' substitutions
+  with `subsnormal` and `subsverbatim` entries in configuration file
+  `miscellaneous` section.
+- By default `AttributeEntry` values are substituted for
+  `specialcharacters` and `attributes`, if you want a different
+  AttributeEntry substitution set the `attributeentry-subs` attribute.
+- The `name` in `name=value` configuration file entries can now end
+  with a backslash, just escape the trailing backslash with a
+  backslash. For example:
+
+  abc\\=xyz
++
+Results in `name=abc\` and `value=xyz` --  previously this would have
+escaped the `=` character.
+
+- A blank configuration file section deletes any preceding section
+  with the same name (applies to non-markup template sections).
+- A command-line attribute value with a `@` suffix does not override
+  existing document and configuration file attributes (normally
+  command-line attributes have precedence over document and
+  configuration file attributes).
+- `localtime` attribute is now encoded from the native system encoding
+  to the output encoding. Patch submitted by
+  mailto:m_pupil@yahoo.com.cnFKtPp -- here's his description of the
+  problem:
++
+``I am a Chinese user of AsciiDoc and I find that when I use UTF-8
+(the default encoding) to write asciidoc documents in Windows platform
+the resulting html footer line will get screwed. It was caused by a
+localized tzname that was always encoded in the windows native
+encoding, which in my case is 'cp936'.''
+
+- a2x(1) can generate Open Document Text files using
+  http://open.comsultia.com/docbook2odf/docbook2odf. Currently
+  `docbook2odf(1)` only processes a subset of DocBook, unimplemented
+  elements are skipped.
+- The a2x(1) format option defaults to `xhtml` (previously a format
+  had to be specified explicitly).
+- The `-d, \--doctype=DOCTYPE` option has been added to a2x(1) which
+  is a shortcut for `--asciidoc-options="--doctype=DOCTYPE"`.
+- Replaced a2x(1) `--no-icons` and `--no-copy` options with their
+  negated equivalents: `--icons` and `--copy` respectively. The
+  default behavior has also changed: copying and use of icons is
+  disabled by default. Rationale:
+  * To make the default behavior more consistent since use of icons
+    and CSS stylesheets does not apply to all formats.
+  * To make the default behavior less surprising (the creation of icon
+    and stylesheet output files must now be explicit).
+
+- a2x(1) has been bumped from version 0.1.1 to version 1.0.0.
+
+
+.Bug fixes
+- Removed duplicate `./doc/a2x.1.txt` from distribution tarball.
+- Documentation errata.
+- Attribute replacement is no longer performed twice in Titles and
+  AttributeEntrys.
+- a2x(1) skipped asciidoc(1) execution when rerun with different
+  `--asciidoc-options` options, it now always executes asciidoc(1).
+  The problem was that previously asciidoc(1) was executed only if the
+  output file was missing or older than the source file.
+
+
+Version 7.1.2 (2006-03-07)
+--------------------------
+.Additions and changes
+- Support for
+  http://www1.chapman.edu/~jipsen/mathml/asciimath.htmlASCIIMathML
+  has been added. See 'Appendix I: ASCIIMathML Support' in the User
+  Guide and the examples at
+  http://asciidoc.org/asciimath.html.
+- You can now prefix quoted text with inline attributes lists.  You
+  can use this to set font size and color (XHTML and HTML outputs).
+- Added `##...##` quoting -- it does nothing -- it's purpose is to
+  allow inline attributes to be applied to normal text.
+- An 'inline passthrough' mechanism has been implemented.
+- Configuration file comment lines can be escaped with a backslash --
+  this is to allows the inclusion of configuration lines that start
+  with a hash character.
+- The `scriptsdir` attribute can be used to specify the name of the
+  directory containing linked JavaScripts (see the
+  link:userguide.html#X33User Guide for details.
+- The BackendBlock has been renamed PassthroughBlock for consistency
+  with the new inline passthrough naming.
+- `a2x(1)` now works with the older `bash(1)` version 2.05b. Patch
+  submitted by mailto:francis@daoine.orgFrancis Daly.
+- Content included by the `include1::` system macro is no longer
+  subject to attribute substitution so that ambiguities no longer
+  arise when used to include CSS or JavaScript files.
+
+
+Version 7.1.1 (2006-02-24)
+--------------------------
+.Additions and changes
+- The `caption` attribute can be used to customize admonition captions
+  as well as image, table and example block element title prefixes
+  (`xhtml11` and `html4` backends).
+- You can now override the default icon image using the `icon`
+  attribute to specify the path of the linked image (xhtml11 and html4
+  backends only).
+- The deprecated `imagesdir` attribute is no longer recognized (use
+  `iconsdir` instead).
+- Added 'Appendix H: Using AsciiDoc with non-English Languages' to the
+  AsciiDoc User Guide.
+- Added 'Admonition Icons and Captions' subsection to the User Guide
+  explaining how to customize Admonition elements.
+
+.Bug fixes
+- `a2x(1)` failed when configuration files were installed in the
+  global `/etc/asciidoc/` directory -- it was only searching the
+  directory containing the asciidoc executable (thanks to Christian
+  Wiese for finding and submitting a patch this bug).
+- The html4 backend admonition caption now correctly displays the
+  admonition `caption` attribute (previously displayed the `style`
+  attribute).
+
+
+Version 7.1.0 (2006-01-13)
+--------------------------
+.Additions and changes
+- `a2x(1)` toolchain wrapper utility.  This overcomes the biggest
+  hurdle for new users which seems to be assembling and using a
+  working DocBook XML toolchain. With `a2x(1)` you can generate XHTML
+  (chunked and unchunked), PDF, man page, HTML Help and text file
+  outputs from an AsciiDoc input file with a single command.  All you
+  need to install (in addition to AsciiDoc) is xsltproc(1), DocBook XSL
+  Stylesheets and optionally FOP (if you want PDF) or lynx(1) (if you
+  want text).
+- Block titles can now start with any non-space character (previously
+  where not allowed to start with `.~-_` characters).
+- `./stylesheets/docbook.css` renamed to
+  `./stylesheets/docbook-xsl.css` to clarify its function.
+- Renamed `./docbook-xsl/manpages.xsl` to `./docbook-xsl/manpage.xsl`
+  for consistency.
+- Admonition and navigation icons moved to `./images/icons/` to
+  clarify usage and conform with a2x(1) usage.
+- Renamed xhtml11 intrinsic attribute `imagesdir` to `iconsdir` to
+  keep vocab consistent and changed default value to `./images/icons`
+  (previously `./images`). `imagesdir` attribute still accepted but
+  deprecated.
+- Unused image files have been weeded out of the distribution.
+- Packager notes (appendix B) have been updated to reflect the needs
+  of `a2x(1)`.
+
+IMPORTANT: The renaming of the xhtml11 backend `imagesdir` intrinsic
+attribute and it's new default value introduces a backward
+compatibility issue: if you use the `icons` attribute you will need to
+either move your icons to the new default `./images/icons` location or
+include an `--attribute{nbsp}iconsdir="your_icons_path"` option in
+your asciidoc commands.
+
+.Bug fixes
+- Backslash line continuation is now observed in verbatim paragraphs.
+- Fixed errors generated by example
+  `./examples/website/build-website.sh` script.
+
+
+Version 7.0.4 (2005-12-08)
+--------------------------
+.Additions and changes
+- Added ternary conditional attributes
+  `{<name>@<regexp>:<value1>:<value2>}` and
+  `{<name>$<regexp>:<value1>:<value2>}`.
+- Safety violations now generate errors (they previously generated
+  warnings).
+- asciidoc(1) now defaults to safe mode, consequently the
+  `miscellaneous` safe mode entry and `--safe` command-line option
+  are no longer necessary (though for backward compatibility
+  asciidoc(1) still accepts the `--safe` option).
+- Backend Blocks are now flagged unsafe (they could be used to include
+  arbitrary and hence potentially unsafe output content).
+- Filters are no longer considered unsafe. There's not much point in
+  insisting on filter safety since the installation of an unsafe
+  filter would require the introduction of new or modified
+  configuration files -- if your application configurations can be
+  compromised you're in all sorts of trouble (safe mode protects
+  against unsafe input files not unsafe configuration).  As with all
+  filters, before installing, you should verify that they can't be
+  coerced into generating malicious output or exposing sensitive
+  information.
+
+.Bug fixes
+- Fixed a lot of glaring grammatical and factual errors in the User
+  Guide.
+
+
+Version 7.0.3 (2005-12-01)
+--------------------------
+.Additions and changes
+- Added `--safe` and `--unsafe` command-line options -- AsciiDoc can
+  now be executed in a 'safe mode' which disallows the execution of
+  arbitrary code or the inclusion of arbitrary files (see
+  link:userguide.html#X39Appendix C in the AsciiDoc User Guide).
+- Included link:source-highlight-filter.htmlsource-highlight filter
+  in the distribution `./examples/source-highlight-filter/` directory
+  (based on filter submitted by mailto:trolocsis@gmail.comRyan
+  Phillips).
+- Included the DocBook XSL Stylesheets 1.69.1 customizations used to
+  generate the distributed AsciiDoc documentation (read the
+  `asciidoc-docbook-xsl.txt` file in the distribution `./docbook-xsl/`
+  directory).
+- AsciiDoc DocBook XSL Stylesheet drivers moved from `./doc/` to
+  `./docbook-xsl/`.
+- Modified `./doc/manpages.xsl` so only URL content is displayed in
+  manpages.
+
+.Bug fixes
+- Explicitly set table CSS border style (`xhtml11` backend) to `solid`
+  because default border styles vary from browser to browser.
+
+
+Version 7.0.2 (2005-08-28)
+--------------------------
+.Additions and changes
+- There are now long versions of all AsciiDoc options.
+- If the `--backend` is not specified it defaults to `xhtml11`.
+- Added CSS simulated frames layout to the examples website (see
+  `./examples/website/layout2/README-website.txt`). This layout does
+  not work with IE6 and the original tables based layout is still the
+  default.
+- Support page added to AsciiDoc website.
+
+.Bug fixes
+- Invalid options are now trapped gracefully.
+- Documentation errata.
+
+
+Version 7.0.1 (2005-06-24)
+--------------------------
+.Additions and changes
+- Reverted to use of `strong`, `em`, `tt` XHTML tags -- they're more
+  obvious and no less correct than `span` tags, besides, the generated
+  file sizes are smaller (the 'User Guide' was 11% smaller).
+- Table title rendered with `caption` tag rather than a separate
+  `div`.
+- The AsciiDoc 'stylesdir' attribute (if specified) is now recognized
+  when searching for embedded stylesheets (previously only searched
+  default `./stylesheets` directory).
+- Default charset encoding changed from ISO-8859-1 to UTF-8 -- it's
+  less language specific and displays most common languages.
+- `template::` macros now expand in all configuration file sections
+  previously only in markup template sections.
+- Cleaned up example website layout CSS and configuration
+  (presentation has not been changed).
+- Refactored `xhtml11.conf` configuration file.
+- Set consistent and sensible permissions on distributed files.
+- White space is now stripped from DSV formatted table cell data.
+- `class="tableblock"` attribute added to tables generated by
+  `xhtml-deprecated-css.conf` to assist CSS.
+
+.Bug fixes
+- Illegal character set encoder (specified by the AsciiDoc `encoding`
+  attribute) and character data are trapped gracefully.
+- AsciiDoc table 'format' attribute in table attribute lists were not
+  recognized.
+- The nested horizontal labeled list example in the 'AsciiDoc User
+  Guide' has been dropped -- it generated invalid DocBook markup.
+
+
+Version 7.0.0 (2005-06-06)

+***************************************************
+
+.Additions and changes
+- A new 'xhtml11' backend generates XHTML 1.1 with integrated CSS2
+  replacing the previous 'xhtml', 'css', and 'css-embedded' backends.
+- The CSS stylesheets have finally been rewritten.
+- The asciidoc(1) command help now includes user
+  link:userguide.html#X36customizable help topics. When asciidoc is
+  invoked with the `--help` option the command argument is
+  interpreted as a help topic.
+- The previous example website has been replaced by the actual
+  AsciiDoc website (see `./examples/website/`.
+- XHTML generation options now controlled by the following attributes:
+  'badges', 'linkcss', 'icons', 'numbered', 'quirks', 'theme',
+  'stylesdir', 'imagesdir' (see the link:userguide.html#X33User
+  Guide for details.
+- By default HTML and XHTML are output as stand-alone documents (no
+  embedded CSS and no linked admonition icon images).
+- Documents encoded with the UTF-8 Unicode character set are now
+  processed thanks to a patch supplied by
+  mailto:viktor@rbg.informatik.tu-darmstadt.deViktor Vasilev.
+- The `-a ^name` command-line syntax to undefine an attribute has been
+  deprecated in favor of the `-a name!` syntax.
+- AttributeEntry syntax addition: `:name!:` to undefine `name` attribute.
+- Added `template` system block macro to allow the inclusion of one
+  configuration file template section within another.
+- A 'verse' style attribute can now be applied to literal paragraphs
+  and blocks to reproduce line breaks and white space from the source
+  document.
+- Replacements and Special Words can now be escaped with leading
+  backslashes.
+- Replacements are now processed in configuration file order (previous
+  ordering was indeterminate).
+- System macros can now be used in the base `asciidoc.conf`
+  configuration file.
+- Deprecated features that emitted warnings in prior versions are no
+  longer tolerated.
+- The `eval` system attribute expression evaluates to `False` the
+  attribute is undefined, if it evaluates to `True` the result is an
+  empty string.
+- The Paragraph and DelimitedBlock 'presubs' parameter can be aliased
+  as 'subs'.
+- Added 'verbatim' substitutions option.
+- Renamed 'List Continuation Block' to 'List Block' and renamed the
+  'listcontinuation' option to 'list'.
+- Deprecated 'default' substitutions option (use 'normal' instead).

+  'numbered'.
+- Dropped the '\#UNDER CONSTRUCTION#' block macro.
+- Rewrote Paragraph and DelimitedBlock handlers adding a
+  link:userguide.html#X23styles configuration entry.
+
+.Bug fixes
+- Included files are no longer read inside conditionally excluded
+  content.
+- Manpage command names containing dashes (in the manpage NAME
+  section) were misinterpreted as the spaced dash command name/purpose
+  separator.  Bug report and patch supplied by
+  mailto:david@dgreaves.comDavid Greaves.
+- Unexpected error following malformed author line error.
+
+
+Version 6.0.3 (2005-04-20)
+--------------------------
+.Additions and changes
+- Special characters are now substituted in AttributeEntry element
+  values.
+- Spaced and unspaced em dashes are now recognized (previously only
+  spaced em dashes were recognized).
+- Replaced the table 'noborders' option with richer 'frame' and 'grid'
+  attributes.
+- The `duplicate macro` warning message now only occurs when the
+  verbose (`-v`) option is enabled.
+- Single lines starting with two forward slashes hard up against the
+  left margin are treated as comments and are not processed.
+- Renamed 'section' delimited block option to 'sectionbody' to more
+  accurately reflect it's role.
+- Added a List Continuation block -- a specialized delimited block
+  that is functionally equivalent to the List Item Continuation
+  feature except that the list contained within the block does not
+  require explicit '+' list item continuation lines.
+- Dropped deprecated `<u>` tags from generated HTML.
+- Literal Block delimiters must now consist of at least four points
+  (previously three) to avoid lone ellipsis ambiguity.
+
+.Bug fixes
+- Some system attribute evaluation failures caused unexpected
+  exceptions to occur.
+
+
+Version 6.0.2 (2005-03-30)
+--------------------------
+.Additions and changes
+- Three new 'system' block macros have been added -- `eval`, `sys` and
+  `sys2` which are the block macro equivalents to the same named
+  system attributes.
+- 'Intrinsic' macros have been renamed 'system' macros along with
+  'action' attributes which have been renamed 'system' attributes:
+  * To reflect their common (though contextually different) behavior.
+  * To avoid confusion with 'intrinsic attributes'.
+
+.Bug fixes
+- Asciidoc now searches in `/etc/asciidoc/filters` for filters.
+
+
+Version 6.0.1 (2005-03-06)
+--------------------------
+.Additions and changes
+- A global configuration file location `/etc/asciidoc` has been added
+  and is now processed before all other locations (patch supplied by
+  mailto:stone@debian.orgFredrik Steen).
+- Recoded `tempfile.mktemp()` and other artifacts that are no longer
+  necessary or desirable (patches supplied by
+  mailto:stone@debian.orgFredrik Steen).
+- Added BUGS file to the distribution.
+
+.Bug fixes
+- Illegal comment syntax in `css-embedded-stylesheet.conf` resulted in
+  illegal CSS in files generated by the `css-embedded` backend.
+
+
+Version 6.0.0 (2005-01-28)
+--------------------------
+***************************************************
+This release has had some fairly major code and
+documentation changes. Please report any problems
+you encounter.
+
+mailto:srackham@gmail.com'Stuart Rackham'
+***************************************************
+
+A lot of new stuff. A new major version number -- some regression
+incompatibility (hopefully mitigated by 'deprecated' warnings).
+
+Went mad trying to rein in the current feature anarchy -- established
+a unified notion of document attributes. Attempted to introduce a
+consistent vocabulary -- renamed many poorly or inconsistently named
+entities.
+
+Actually, deprecated syntax is still processed correctly in almost all
+cases. One source of incompatibility that may arise if you have
+customized CSS stylesheets is the change of AsciiDoc CSS class names
+(see below). I guess the moral is if you've done a lot of
+configuration file customization and are happy with version 5 then you
+may want to stay put.
+
+NOTE: This version requires Python 2.3 or better to run.
+
+.Additions and changes
+- 'Glossary entries' have been renamed 'attributes'. This eliminates
+  confusion with the accepted meaning of glossary.
+- An `AttributeEntry` block element has been added so that document
+  attributes can be assigned from within an AsciiDoc document.
+- The `AttributeList` block element has been added which is a more
+  general solution than the (now deprecated) DelimitedBlock arguments.
+- An BlockId element has been added for setting block element anchor
+  (link target) IDs.
+- Quoted text can now span multiple lines (thanks to James Bowlin for
+  this patch).
+- Inline macros can now span multiple lines.
+- \``double backtick / apostrophe'' quotes generate ``curly quotes''.
+- A warning is now emitted for out of order list item (applies to
+  explicitly enumerated numbered list items).
+- Added `include` action attribute.
+- A line of three or more apostrophes generates an HTML horizontal
+  ruler (`<hr/>` tag). You will get a warning if processed with
+  non-HTML backend.
+- An `{imagesdir}` attribute specifies image file location for images
+  referenced in configuration files when generating HTML (the default
+  location is `images`).
+- An `{stylesdir}` attribute specifies the location of CSS
+  stylesheets when generating styled HTML (the default location for
+  configured markup is `.`).
+- The use of the (often inappropriately named) `{caption}` attribute
+  list entry has been deprecated, use `{0}` instead.
+- New 'ExampleBlock' delimited block along with associated variants
+  Note, Tip, Warning, Caution and Important.
+- The `docbook.conf` file now facilitates the optional inclusion of a
+  DocBook revision history file.
+- To better reflect their purpose the following block elements have
+  been renamed: `VerbatimBlock` to `ListingBlock`; `IndentedBlock` to
+  `LiteralBlock`; `IndentedParagraph` to `LiteralParagraph`;
+  `CustomBlock` to `BackendBlock`; `SimpleSection` to `SectionBody`.
+  Any corresponding CSS class names have also been changed which could
+  result in backward incompatibility in customized stylesheets.
+- Swapped plain DocBook admonition icons for Jimmac's DocBook icons
+  (http://jimmac.musichall.cz/ikony.php3). The original plain icons
+  have been moved to `./images/plain`.
+- Renamed `html` backend to `xhtml` to better reflect it's function
+  (former `html-4` backend renamed to `html`).
+- A new inline anchor macro syntax `<id>` is available, it
+  displays `<id>` at the anchor location and is for anchoring
+  bibliography list entries.
+- An optional 'single-line titles' syntax can be used.
+- Tweaks to distributed CSS stylesheets and FOP `fo.xsl` customization
+  file.
+- 'List Item Continuation' has been implemented which allows
+  additional block elements to be included in list items by separating
+  them from the preceding list item element with a line containing a
+  single plus character.
+- A new 'Horizontal Labeled List' list type has been added. Generates
+  two column list -- the first column contains the list element
+  labels, the second contains the element text. Same syntax as
+  `Vertical Labeled Lists` except the double colon label suffix is
+  followed by the start of the list item text.
+
+.Bug fixes
+- Fixed broken backslash line continuation.
+- Labeled list end tags were not undergoing attribute substitution.
+- Documents without any author information now generate legitimate
+  DocBook (previously if the author line was not included in the
+  document header then an empty (illegal) DocBook `author` element was
+  generated).
+- Multiple spaces in filter command arguments were replaced by a
+  single space. The `./examples/asciidoc2text/asciidoc2text.sh` script
+  now indents text correctly.
+
+
+Version 5.1.1 (2004-10-10)
+--------------------------
+*15-December-2004: Interim update:* Updated `asciidoc.py` to fix
+broken `join_lines` function -- no other changes.
+
+- PDF documentation is now produced from DocBook XML using XSLTLib and
+  FOP. Previously we processed DocBook SGML with `jw(1)` (which used
+  Dvips to convert DVI files to PDF). FOP has come a long way in the
+  last 12 months and produces very acceptable PDF under both Linux and
+  Windows.
+- Sections detailing how to install and use the DocBook XSL
+  Stylesheets, xsltproc, FOP toolchain and the AsciiDoc XSLT drivers
+  have been added to the User Guide.
+- The PDF output from the he example article template has been
+  included in the distribution (`./doc/article.pdf`).
+- Special characters are emitted using decimal Unicode character codes
+  (previously used named character entities which cannot be assumed
+  included in non-HTML documents).
+- Added registered trademark (R) to `replacements`.
+- CSS stylesheet tweaks.
+- Admonitions (Note, Tip, Important, Warning, Caution) include icons
+  when generating css output.
+
+
+Version 5.1.0 (2004-09-18)
+--------------------------
+- Callouts have been implemented (see the 'Callouts' section of the
+  AsciiDoc User Guide for details).
+- Added XSL drivers for generating XHTML, chunked XHTML and HTML Help
+  from DocBook XML using XSL stylesheets and xsltproc(1).
+- Added CSS stylesheet for HTML generated from DocBook XML using XSL
+  stylesheets.
+- Distribution contains HTML Help formatted User Guide
+  (`./doc/asciidoc.chm`), the User Guide tells you how it's generated.
+- Images referred to by distributed stylesheets are now located in the
+  `./images` subdirectory (previously located in `.`).
+- Filters path names are now handled properly under Cygwin.
+- The usual documentation and examples additions, updates and
+  polishing.
+
+
+Version 5.0.9 (2004-09-09)
+--------------------------
+- The convention of using a `.asc` file extension for AsciiDoc files
+  has been dropped in favor of the familiar `.txt` extension. It makes
+  more sense in that AsciiDoc is a text presentation format and
+  because `.asc` clashed with the same extension used by other
+  applications.  It's only a naming convention -- you don't have to
+  switch if you don't want to.
+- Changed the subscript formatting character from underline to tilde
+  since underscores in file names are reasonably common (especially in
+  link and image macros).
+- An alternative syntax for the index term inline macro has been
+  added: `++<primary>,<secondary>,<tertiary>++`.
+- Index terms that have secondary and tertiary entries now
+  additionally generate separate index terms for the secondary and
+  tertiary entries.
+- A `+<primary>+` index term inline macro has been added which
+  displays the term in the primary text flow.
+- Added alternative variable list definition using double semi-colon
+  terminator as opposed to the standard double colon terminator so
+  variable lists can be nested to two levels.
+- Footnotes now appear on a separate line in HTML and Linuxdoc
+  outputs.
+- Python version compatibility is checked at startup.
+- Preface and appendix section titles in multi-part Book documents are
+  meant to be out of sequence -- warnings are no longer emitted when
+  outputting HTML.
+- Empty section warnings have been replaced by error messages and are
+  emitted only if invalid markup would result.
+- Missing macro sections or invalid macro name warnings are only
+  generated at startup if the `-v` (verbose) option is set. Otherwise
+  they are deferred until a matching macro is encountered in the input
+  file.
+- Missing or invalid table definition warnings are only generated at
+  startup if the `-v` (verbose) option is set. Otherwise they are
+  deferred until a matching table is encountered in the input file.
+- AsciiDoc now makes more of an effort to continue in the face of
+  errors.
+- Fixed broken `./examples/website/main.aap` script.
+- Converted distribution text files DOS text format as a sop to
+  Windows users with challenged text editors.
+- Documentation additions and corrections.
+
+
+Version 5.0.8 (2004-05-15)
+--------------------------
+- Spurious 'out of sequence' level 2 warnings no longer appear when
+  processing 'book' document multi-part book top level Preface and
+  Appendix sub-sections since they are (correctly) out of sequence.
+- A warning is no longer emitted for empty Index sections since this
+  is normal when generating DocBook outputs.
+- Fixed: `quotes` configuration file entries where not being
+  overridden by downstream configuration file entries.
+- Footnote text is now output enclosed in square brackets in HTML
+  documents.
+- Added superscripts and subscripts to the standard PRS configuration
+  files.
+- Adjusted CSS stylesheets so list titles don't have so much space
+  between title and first list item (broken in IE6 due to poor CSS
+  compliance). Lessened sidebar title top margin.
+
+
+Version 5.0.7 (2004-04-22)
+--------------------------
+- The version 5.0.6 README incorrectly stated that AsciiDoc would run
+  under Python 2.0, in fact it requires Python 2.1 or better. The
+  README has been corrected.
+- Documented techniques for combining and splitting AsciiDoc documents
+  and processing the combined and split parts (see the 'Tips and
+  Tricks' section of the User Guide).
+- An example of marking up superscripts and subscripts is documented
+  in the 'Tips and Tricks' section of the User Guide (the example
+  configuration file is in the AsciiDoc `examples` directory).
+- Added ellipsis to shipped `replacements`; three periods output an
+  ellipsis entity.
+- Removed unused 'SectionClose' class.
+- The AsciiDoc 'Preamble' element is output as a DocBook 'Preface'
+  when processed as a 'book' document type (in older AsciiDoc versions
+  a warning was issued and processing stopped).
+- Fixed a quoting anomaly: quoted text can no longer begin or end with
+  with white space.
+
+
+Version 5.0.6 (2004-03-07)
+--------------------------
+- New 'image' macro implements optional image scaling and linking and
+  works in both inline and block contexts. The 'image' macro obsolesces
+  the existing 'graphic' block macro and 'icon' inline macro.
+- Macro substitution section names now have `-inlinemacro` and
+  `-blockmacro` suffixes to resolve context ambiguity, make their
+  purpose clearer and relieve section namespace congestion.
+- Header derived glossary entries can now be overridden from the
+  command-line.
+- Special character substitution is now performed on AuthorLine
+  derived author names.
+- A macro or block argument called 'options' can be used as a shortcut
+  for a list named arguments with zero length string values.
+- Tables can be output without borders using the `options="noborders"`
+  argument.
+- Table data lines that do not immediately follow a table section
+  underline can now be blank. This allows CSV data with embedded blank
+  lines to be processed correctly.
+- Blank DSV format table data lines are silently skipped.
+- Tightened up on enforcement of configuration file section names to
+  reduce the possibility of section content being seen as a section
+  header line.
+- Section titles can be optionally suffixed with title arguments
+  enclosed in double square brackets.
+- A replacement has been added to `asciidoc.conf` to replace inline
+  double dashes with the `&mdash;` entity.
+- Changed the `.UNDER-CONSTRUCTION.` macro syntax to
+  `#UNDER-CONSTRUCTION#` so it is not mistaken for a BlockTitle.
+  Similarly changed the `.NEW.` replacement with
+  `&#35;NEW&#35;`.
+- `&#35;NEW&#35;` and `#UNDER-CONSTRUCTION#` macros are now
+  included in the DocBook backend.
+- Replaced shipped `smallnew.gif` with `smallnew.png`.
+- Documentation tidy ups.
+
+
+Version 5.0.5 (2004-02-25)
+--------------------------
+- Fixed the disappearing paragraph titles problem that was caused by
+  Inline macros (incorrectly) processing BlockTitles.
+- Tightened AuthorLine validation.  Previously invalid email addresses
+  and embedded special characters in the AuthorLine resulted in
+  invalid output markup.
+
+
+Version 5.0.4 (2004-02-09)
+--------------------------
+- Reinstated missing `infile`, `outfile`, `filetype` and
+  `filetype-<filetype>` glossary entries.
+- As of version 5.0.3 asciidoc(1) now requires Python 2.0 or greater,
+  this has now been documented.
+
+
+Version 5.0.3 (2004-01-23)
+--------------------------
+- Fixed problem that caused any filters directory file containing
+  `.conf` (not just those with the `.conf` extension) from being
+  loaded.
+- All `miscellaneous` configuration file entries can now be
+  referenced like glossary entries (they are now processed internally
+  as glossary entries).
+- The output file line terminator (previously hardwired to `\r\n` is
+  now set using the `newline` entry in the configuration file
+  `miscellaneous` section.
+- The misspelt `blocktitles` configuration file entry name has been
+  corrected (to `blocktitle`).
+- An `{empty}` glossary entry has been added to the default
+  configuration which is useful for outputting trailing blank lines
+  from configuration file substitution sections.
+
+
+Version 5.0.2 (2003-12-18)
+--------------------------
+- New (alternative) 'anchor' and 'xref' macro syntax (old syntax still
+  valid).
+- DocBook `mediaobject` and `inlinemediaobject` tags are generated in
+  place of `graphic` and `inlinegraphic` tags by the AsciiDoc
+  `graphic` and `icon` macros. If a macro argument is specified it is
+  the alternative text output if the target document format does not
+  support the specified graphic file format.
+- Dropped the LinuxDoc left and right square bracket special character
+  substitutions as they interfered with macro substitution.
+- Documentation updates and corrections.
+
+
+Version 5.0.1 (2003-12-09)
+--------------------------
+- Fixed problem with anchor tag when generating CSS styled HTML.
+
+
+Version 5.0 (2003-12-08)
+------------------------
+***************************************************
+This release has had some fairly major code and
+documentation changes. Please report any problems
+you encounter.
+
+mailto:srackham@gmail.com'Stuart Rackham'
+***************************************************
+
+- AsciiDoc can now produce a full-blown multi-part DocBook book
+  including dedication, abstract, preface, colophon, glossary,
+  appendix, bibliography and book part elements using the new
+  `specialsections` configuration file section.
+- All Section element children (Paragraph, DelimitedBlock, List,
+  Table, BlockMacro) can now be titled using the BlockTitle element.
+  A BlockTitle element is a single line containing a title and
+  beginning with a period.
+- The `index` and `backmatter` macros have been dropped, superseded by
+  `specialsections`.
+- The AsciiDoc 'Preface' element has been renamed 'Preamble' (to avoid
+  confusion with the DocBook book preface element).
+- Out of sequence titles are now tolerated with a warning. This allows
+  book document level 0 sections to be processed.
+- An 'anchor' inline macro has been added for document link target
+  creation.
+- 'Note', 'Tip', 'Important' and 'Warning' paragraph types have been
+  added to support the corresponding DocBook elements.
+- Title substitution is now performed in SidebarBlock titles.
+- DocBook graphics now output as `figure` and `informalfigure`
+  elements rather than `mediaobjects`. This ensures numbered figures
+  and a lists of figures are produced by the DocBook toolchain.
+- You can now escape block argument lines by appending a backslash.
+  Alternatively, if you embed arguments in the delimiter line AsciiDoc
+  does not check for an arguments line.
+- The default DocBook backend file extension has been changed from
+  `.docbook` to `.xml` (`.sgml` for the 'docbook-sgml' backend).
+- Warnings are output by default (previously they only printed when
+  verbose option enabled).
+- A Question and Answer variable list definition has been added to the
+  shipped configuration files, primarily to create DocBook `qanda`
+  DocBook elements.
+- Fixed broken code-filter `-b linuxdoc` option. The asciidoc.asc User
+  Guide can now be processed by linuxdoc(1) (although tables are
+  dropped because LinuxDoc does not implement tables).
+
+.Compatibility issues:
+1. Table titles are no longer in the arguments line, use the new
+   BlockTitles.
+2. Graphic titles are no longer in the 'graphic' block macro caption,
+   use the new BlockTitles.
+3. The code-filter title must be placed in a preceding BlockTitle.
+4. SidebarBlock titles must be placed in a preceding BlockTitle.
+5. The DelimitedBlock option 'sidebar' has been renamed to 'section'.
+6. The default DocBook backend file extension has been changed from
+`.docbook` to `.xml` (`.sgml` for the 'docbook-sgml' backend).
+
+
+Version 4.2 (2003-11-26)
+------------------------
+- The default HTML output is now XHTML 1.0 markup. To output the
+  former HTML 4 markup specify the `html-4` backend.
+- The default DocBook output is now DocBook XML. To output the former
+  DocBook SGML specify the `docbook-sgml` backend. The associated
+  `docbook-sgml.conf` file illustrates how to support minor DTD
+  variations. Examples of using the `xmlto(1)` command for DocBook
+  conversion have been added to the User Guide.
+- Glossary entries set using the command-line -g option can now be
+  referenced in configuration files.
+- Configuration dumps (`-c` command-line option) no longer output
+  redundant undefined glossary entries.
+- DelimitedBlock arguments can now be specified in a separate arguments
+  line immediately following the leading delimiter line, This is in
+  preference to the existing delimiter embedded arguments. Reasons:
+  * The syntax is in keeping with the Tables arguments syntax.
+  * It's easier to enter and implements line continuation.
+- A new QuoteBlock DelimitedBlock definition has been added to the
+  distribution configuration files.
+- The table arguments lines can be continued using the backslash line
+  continuation character.
+- Added new calculated glossary reference type `{<name>%<value>}`.
+- Double-quote characters can now appear in unquoted positional
+  arguments.
+
+
+Version 4.1 (2003-11-13)
+------------------------
+- Added DSV (Delimiter Separated Values) tables format.
+- `{eval:<expr>}` glossary references drop the containing line if
+  `<expr>` evaluates to `None`.
+- Block, Table and Macro arguments can now be positional (quoted or
+  unquoted).
+- Vocabulary change: DelimitedBlock, Table and Macro 'attributes' are
+  now referred to as 'arguments'. This makes more sense in light of the
+  extended syntax and avoids confusion with backend markup tag
+  attributes.
+- 'tablewidth' table ruler parameter can now be expressed in percent
+  units (0..100). If between 0 and 1 then the original fractional unit
+  measure is applied.
+- The use of quoting for generating footnotes and index entries has
+  been dropped in favor of 'footnote' and 'indexterm' inline macros.
+- 'backmatter' inline macro included in distribution.
+- Fixed: CSS styled HTML tables are now fully XHTML 1.0 conformant.
+- Fixed: 'tablewidth' was processed incorrectly when passed as table
+  argument.
+- Fixed: Glossary references like `{x=\{y}}` were one character off
+  if \{x was defined and `{y}` was not.
+
+
+Version 4.0 (2003-11-08)
+------------------------
+***************************************************
+This release has had some fairly major code and
+documentation changes. Please report any problems
+you encounter.
+
+'Stuart Rackham'
+***************************************************
+
+- Added tables to AsciiDoc.
+- Added two special 'subs' options: 'default' specifies the default
+  substitution options and 'none' specifies no substitution.  These
+  options can only appear singly.
+- Line continuation using a trailing backslash character is available
+  in Paragraphs, ListItems, Tables.
+- The left and right quotes for quoted text can now be specified
+  separately.
+- Shipped configuration files implement footnotes (only useful for
+  DocBook output) using \ quoting.
+- Shipped configuration files implement index terms (only useful for
+  DocBook and LinuxDoc output) using \(()) quoting.
+- The shipped 'html' backend configuration now emits valid 'HTML 4.01
+  Transitional'.
+- Added new calculated glossary reference types `{<name>!<value>}`
+  and `{<name>#<value>}`.
+- The DelimitedBlock 'params' option has been dropped in favor of the
+  new 'block attributes' mechanism. If you have customized block
+  params options you may need to adjust source files to use the
+  'block attributes' syntax. The example code filter has been updated
+  to reflect these changes.
+- The code filter now has a `-t tabsize` option.
+- Replaced `-w` option with `-v` (verbose) option. The warnings option
+  was just to confusing.
+- Named attributes can now be specified in macro calls.
+- The 'tabsize' attribute is recognized in the built-in `include`
+  macros. A tabsize of zero suppresses tab expansion.
+- The configuration file `options` section has been split into
+  `miscellaneous` and `titles`. If you have customized any of
+  these settings you will need to adjust the affected configuration
+  files.
+- Configuration file `miscellaneous` entries can now also be set
+  using the command-line `-g` option.
+- Fixed: error that occurred when attempting to use zero length
+  configuration and source files.
+- Fixed: blocking filter halt problem.
+- Fixed: inline macro escape prefix problem.
+- Fixed: missing macros from configuration dump problem.
+- Fixed: named macros were dumped incorrectly.
+- Many documentation changes/additions/corrections.
+
+
+Version 3.2.2 (2003-10-26)
+--------------------------
+- Added `-n` option (synonym for `-g section-numbers`).
+- Dropped the processing commentary (hey, this is Unix).
+- Added new calculated glossary reference type `{<name>?<value>}`.
+  `<name>` is the glossary entry name and `<value>` is the text
+  substituted if the glossary entry is defined. `<value>` can only
+  contain literal text (no glossary references allowed).
+- Added `asciidoc2text` to distribution `examples/asciidoc2text`
+  directory (converts AsciiDoc source to text file with section
+  numbering).
+- Fixed incorrect nesting of Simple lists inside Variable lists.
+- List definitions have been modified so that list items can be
+  indented. This allows a more intuitive indentation of nested lists
+  in AsciiDoc source.
+- Lists must be separated from preceding paragraphs by a blank line.
+  This is to avoid paragraph lines being mistaken for list items.
+- Corrected asciidoc man page documentation error: the`-f` option does
+  *not* search relative to source document directory for the
+  configuration file.
+- Minor updates to various distribution `.conf` files.
+- Included `badges.conf` in `examples` directory.
+- `css-embedded-stylesheet.conf` now supports footer badges.
+- The default in-line element processing order has been changed:
+  Glossary References are now processed before Inline Macros. This
+  allows glossary expansions to occur inside macro references.
+- Glossary entries are now allowed in Author and Revision lines.
+- Default List `subs` options and Paragraph `presubs` options are
+  assigned the following default value if not specified:
+
+  specialcharacters,quotes,specialwords,replacements,glossary,macros
+
+- Documentation changes/additions/corrections.
+
+
+Version 3.2 (2003-05-26)
+------------------------
+- Added a `-s` command-line option to suppress the output of
+  `header` and `footer` sections.
+- Article document headers are no longer mandatory: this allows
+  AsciiDoc to process arbitrary chunks of text. When used in
+  conjunction with the new `-s` command-line option corresponding
+  chunks of backend markup can be generated.
+- AsciiDoc now emits a warning message and continues when an out of
+  sequence section title is detected (previously it failed and
+  halted). This allows document sections to be processed separately.
+- Optional 'presubs' and 'postsubs' entries have been added to
+  'DelimitedBlock' and 'Paragraph' definitions. As a consequence
+  substitution options are no longer legal in 'options' entries.
+- 'presubs' and 'postsubs' substitutions are processed in the order
+  the options are specified (rather than the fixed 'options' order of
+  previous versions).
+- ./filters subdirectories are automatically searched for filter
+  commands.
+- A 'title-subs' configuration option specifies the substitutions
+  performed on document Header and Section titles.
+- A 'subs' entry in now included in List configuration file
+  definitions that specified substitutions performed on list entry
+  text.
+- Configuration files are auto-loaded from ./filters subdirectories.
+- Added example code filter (see ./examples/filters).
+- Bug fix: if section was empty you may have got erroneous 'missing
+  tag "paragraph"' error.
+- Internal code tidy up.
+
+
+Version 3.1 (2003-05-18)
+------------------------
+- In version 3.0 a `macros` section entry of the form 'name' was
+  equivalent to 'name='. An entry of the form 'name' now undefines the
+  entry (to bring it in line with the behavior of other special
+  sections).
+- Paragraphs have now been generalized (in the same way as Lists and
+  DelimitedBlocks).
+- The 'indentsize' option has been dropped as as consequence of
+  paragraph generalization.
+- Pipe | characters can be included in substituted tag and
+  substitution section text using the \{brvbar} (broken vertical bar)
+  glossary reference.
+- Removed the restriction requiring substitution section text
+  placeholders | to be on a separate line.
+- Added an `-e` asciidoc(1) command option that excludes implicit
+  configuration files (used in conjunction with `-c` generated
+  configuration files).
+- Version 3.0 documentation has undergone a considerable cleanup.
+- The dumping of quoted section entries (see `-c` option) now works
+  correctly.
+- The format of special section entries has been made consistent:
+  `name` undefines the entry; `name=` sets the entry value to a blank
+  string; `name=value` sets the entry value to `value`.
+- As a consequence of the previous change the caret prefix is no
+  longer used in glossary configuration file entries (although it is
+  still used when undefining an entry using the `-g` command-line
+  option).
+
+
+Version 3.0 (2003-05-13)
+------------------------
+This version is the culmination of work begun in the 2.x releases
+whereby fixed policy has been replaced by extensible mechanisms.
+
+- Added `-c` command-line option to dump a composite asciidoc(1)
+  configuration file to stdout.
+- Lists and Delimited Blocks are now defined by a set of configuration
+  file parameter sections.  The user can modify the default
+  definitions or add new ones.
+- Block content can now be processed through external filters.
+- The default behavior for Custom Blocks is to perform glossary
+  substitution (previously there was no substitution inside Custom
+  Blocks).
+- The old 2.x style macros have been reimplemented; as with Lists and
+  Delimited Blocks there syntax and behavior can be configured by the
+  user. The default macro syntax remains the same but the semantics
+  are now (hopefully) a bit more intelligible.
+- Block and Builtin macros use :: delimiter instead of the 2.x single
+  colon delimit (to distinguish them from inline macros). The 2.x
+  syntax is still supported for backward compatibility.
+- Nested lists are now supported and IndentedParagraphs can be
+  included in list items.
+- Conditional source inclusion can be specified using built in `ifdef`,
+  `ifndef` and `endif` macros.
+- The new conditional source inclusion feature has been used to reduce
+  the number of default configuration files down to one per backend.
+- A change of name: 2.x 'Substitutions' are now called 'Replacements'
+  and the 2.x `substitutions` configuration file section is now
+  called `replacements` (the old name is still recognized for
+  backward compatibility).
+- The line break is now implemented as a 'Replacements' substitution.
+- Inline 'icon' macro for inline images has been added to default
+  configuration files.
+
+Version 2.2 (2003-04-07)
+------------------------
+- The `master.conf` configuration file name has been deprecated in
+  favor of `asciidoc.conf`.
+- The standard configuration files set is now loaded from the
+  `.asciidoc` folder in the users home directory (if it exists) and
+  then from the source document directory. Configuration files that
+  don't exist are silently skipped.
+- Configuration files named like the source file will be automatically
+  loaded if they are found in the source file directory. For example
+  if the source file is `mydoc.asc` and the `-b html` option is used
+  then asciidoc(1) will look for `mydoc.conf` and `mydoc-html.conf` in
+  that order.
+- The characters used to quote formatted text can be configured and
+  extended by the user (see the master.conf quotes section).
+- Quoted text can now be escaped by prefixing a backslash character to
+  the leading quote.
+- The double single-quote '' strong text quote has been deprecated in
+  favor of an asterisk * character.
+- Added \{eval:expression}, \{sys:command} and \{sys2:command}
+  glossary reference actions.
+- Trailing brace characters `}` are now allowed inside glossary
+  references provided they are escaped with a backslash character.
+- Glossary entries can now be escaped by prefixing a backslash
+  character to the leading brace character (use this in preference to
+  placing the backslash inside the brace).
+- The output macro has been deprecated (use the new include1 macro
+  inside a CustomBlock).
+- The default document type is `article` (asciidoc no longer attempts
+  to guess).
+- Files included within DelimitedBlocks are not searched for block
+  termination underlines. This ensures the entire file is part of the
+  DelimitedBlock.
+- `include` macros can now be used in configuration files.
+- Corrected \{infile} and \{outfile} glossary entry documentation.
+- File inclusion is now limited to a depth of 5 to catch recursion
+  loops.
+- Inline tags have been deprecated, they're not necessary and they
+  immediately make the source document backend specific. Use
+  CustomBlocks or Substitutions instead.
+
+Version 2.1 (2003-03-17)
+------------------------
+- Added section auto numbering `{sectnum}` glossary entry
+  (auto-numbering function contributed by Ludovico Magnocavallo).
+- asciidoc(1) now correctly returns non-zero exit status if an error
+  occurs.
+- An AsciiDoc example website has been included in the AsciiDoc
+  distribution `examples/website` directory.
+- NOTE: The `asciidoc` wrapper script included in the 2.0 distribution
+  has been dropped, if you've symlinked or aliased to `asciidoc` you'll
+  need to change them to point directly to `asciidoc.py` instead.
+- An RCS $Id$ marker can be used as the  document header revision line
+  (based on a patch submitted by Ludovico Magnocavallo).
+- In addition to the `name=value` glossary entry format two new ones
+  have been introduced: `name` (the default value is set to an empty
+  string) and `^name` (the glossary entry is undefined).
+- The `-q` command-line option has been deprecated and the `-w level`
+  command-line option added. +
+  NOTE: By default skipped substitution warnings are now suppressed.
+- If a configuration file specified with the `-f` command-line option
+  is not found relative to the current working directory then the
+  search is repeated relative to the asciidoc(1) directory. This
+  allows global configuration files to be used.
+- Added `{infile}`, `{outfile}` predefined glossary entries.
+- Added `under-construction` macro to HTML article configuration
+  files.
+- Deprecated `{asciidoc_version}` glossary entry in favor of
+  `{asciidoc-version}` (to it consistent with other entries).
+
+Version 2.0 (2003-02-24)
+------------------------
+- The emphasized, strong and monospaced words options have been
+  generalized with the introduction of macro based 'special words'
+  lists.
+- Glossary references can now appear in both the document and macro
+  bodies.
+- All output files use `crlf` line termination (previously used UNIX
+  `lf` (newline) termination).
+- Added substitutions section which implements arbitrary regular
+  expression based substitutions.
+- An optional `master.conf` configuration file can be used for entries
+  that are not backend or document type specific.
+- Special character definitions moved from the code to the new
+  special_characters configuration file section.
+- Configuration file glossary added.
+- Command-line -g glossary entry added.
+- A new 'book' document type has been implemented for the 'docbook'
+  backend. It outputs DocBook 'book' documents.
+- A major internal change has been the implementation of parametrized
+  user definable 'macros'. Internally most document elements are now
+  processed as macros.
+- Configuration file macro variables can be specified with default
+  values (literals or other macro variables).
+- An attempt has been made to tighten up the vocabulary used to
+  describe the AsciiDoc document syntax.
+- The term abstract has been replaced by the more general term
+  'preface' and a new preface section introduced into article
+  configuration files (replacing the synopsis sections).
+- Any section elements can now be put in the document preface
+  (previous versions only allowed paragraphs).
+- AsciiDoc Blocks have been unified and their behavior can be user
+  defined and parametrized.
+- An 'output' inclusion allows an external file to be written directly
+  to the backend output file.
+- A new CustomBlock has been added. Default behavior is to insert the
+  enveloped AsciiDoc source lines directly into the output file.
+- A 'line break' tag can be inserted by terminating a line with a '+'
+  character (only really useful for HTML backends).
+- An fourth section level has been introduced.
+- The SidebarBlock delimiter line characters have been changed. The
+  deprecated underline is still accepted.
+- Levels 2 and 3 title underline characters have been changed.  The
+  deprecated underlines are still accepted.
+- Lines with backend specific inline tags can be inserted into
+  AsciiDoc source files.
+- Single words enveloped by underscores are no longer emphasized. This
+  feature was deprecated as it is redundant (use single quotes
+  instead) and was being applied to file names with underscores.
+- A `-q` quiet option has been added to suppress warning messages.
+- Badge images sourced locally.
+- Added 'author' and 'author-mail' meta tags to HTML configuration
+  files.
+
+Version 1.5 (2003-01-08)
+------------------------
+- Implemented sidebar document elements.
+- Explicit checks for user specified configuration files and input
+  file (rather than throwing exception).
+
+Version 1.4 (2003-01-04)
+------------------------
+- New configuration file options 'emphasizedwords' and 'strongwords'.
+  These allow the definition of words that will always be emphasized
+  or rendered in a strong font without inline formatting.
+- Document and section titles are no long subject to inline
+  formatting.
+- Multiple configuration files can be overlaid in a single command.
+- Configuration file tags and options entries can now be overridden on
+  an entry by entry basis (previously the entire section was
+  overloaded).
+- Configuration file tags and options entries are now cached this has
+  resulted in around 37% performance improvement over version 1.3.
+- Variable lists can now contain multiple terms per list item.
+- Placeholder paragraph eliminated from empty sections that contain
+  subsections.
+- Added \{asciidoc_version} substitution variable.
+- More documentation additions and tidy ups.
+
+Version 1.3 (2003-01-01)
+------------------------
+- A new 'strong' text formatting convention has been implemented:
+  Word phrases enclosed in pairs of single quote characters (acute
+  accents) are rendered in a strong font (usually bold).
+- Paragraphs can now be followed immediately by Simple lists and
+  Ordered lists without an intervening blank line.
+- A user specified configuration file (`asciidoc(1)` -f option)
+  overlays the default configuration file rather than replacing it.
+  Custom configuration files need only contain those sections
+  that have been customized.
+- Comment Block delimiters have been relaxed slightly. They must start
+  with three forward slashes /// but the remainder can contain any
+  characters, this allows comments to be embedded in the delimiter line.
+- Leading non-digit characters preceding revision number are now
+  ignored.
+- Set default indentsize option from 2 to documented default value
+  of zero in HTML backend html-article.conf and html-manpage.conf
+  files.
+- Fixed error that occurred when taking input from stdin without
+  explicitly specifying a document type.
+- Restored file name and line number error message information.
+- Changed deprecated -t option to -d in asciidoc --help and usage
+  command output.
+- CSS styles tweaking.
+- Code, configuration file and documentation tidy ups.
+
+Version 1.2 (2002-12-28)
+------------------------
+- Implemented 'include' URL to allow file inclusion.
+- `fileextension` configuration file option renamed to more sensible
+  `outfilesuffix` (`fileextension` still accepted by this version but
+  will be dropped in future).
+- Improved error reporting.
+- CSS backends generate valid XHTML.
+- New `css-embedded` backend generates HTML with embedded stylesheets
+  (use the `css` backend for linked stylesheets). The css-embedded
+  backend output contains no linked images so the generated html files
+  are completely self contained.
+- Bug fixes.
+
+Version 1.1 (2002-12-03)
+------------------------
+- Added css (cascading style sheets) backend
+- Implemented IndentedBlock document element.
+- Tabsize command-line option has been deprecated in
+  favor of configuration file.
+- Default indent width changed to zero.
+- Added \{localdate} and \{localtime} substitution variables.
+- Added optional options configuration file section with
+  fileextension, tabsize and indentsize options.
+- Implemented \{authorinitials} substitution variable.
+- Added https link type.
+- Corrected graphic substitution from \{title} to \{caption}
+  in linuxdoc-article.conf configuration file.
+- Fixed error that occurred when '==' title underline was
+  used.
+
+Version 1.0 (2002-11-25)
+------------------------

+AsciiDoc Installation
+=====================
+
+NOTE: The current version of AsciiDoc requires *Python 3.5 or later*
+to run.  If you don't already have an up-to-date version of Python
+installed it can be downloaded from the official Python website
+http://www.python.org/.
+
+Prerequisites
+-------------
+
+- Python 3.5+
+- DocBook XSL Stylesheets
+- xsltproc
+- w3m
+- dblatex
+- FOP
+- make
+
+Installing from PyPI
+--------------------
+Starting from 10.0 release, AsciiDoc.py can be installed from PyPI repository
+by doing the following:
+
+  $ python3 -m pip install asciidoc
+
+Installing from the GitHub repository
+-------------------------------------
+The AsciiDoc repository is hosted by https://github.comGitHub.
+To browse the repository go to https://github.com/asciidoc/asciidoc-py3.
+You can install AsciiDoc from the repository if you don't have an up to
+date packaged version, or you want to get the latest version from the master
+branch:
+
+- Make sure you have https://git-scm.com/Git
+  installed; you can check with:
+
+  $ git --version
+
+- Go to the directory you want to install AsciiDoc into and download
+  the repository.  This example gets the {revnumber} tagged release:
+
+subs="attributes"
+  $ cd ~/bin
+  $ git clone https://github.com/asciidoc/asciidoc-py3 asciidoc-{revnumber}
+  $ cd asciidoc-{revnumber}
+  $ git checkout {revnumber}
+
+You now have two choices: you can run asciidoc locally from your
+repository (e.g. `python3 -m asciidoc` or `python3 -m asciidoc.a2x`) or you
+can use 'autoconf(1)' and 'make(1)' to perform a system-wide install. If you
+wish to update your installation, run `git pull` and re-run `make(1)` to
+re-install the updated version
+
+Uninstalling AsciiDoc.py
+------------------------
+
+To uninstall AsciiDoc.py, if you installed it via PyPI, then simply do the
+following:
+
+  $ python3 -m pip uninstall asciidoc
+
+If you installed it via `make(1)`, please do the following:
+
+  $ sudo make uninstall
+
+
+X1
+Distribution tarball installation
+---------------------------------
+The distribution source tarballs can be downloaded from GitHub
+releases page https://github.com/asciidoc/asciidoc-py3/releases.
+
+If your flavor of UNIX or Linux does not have a packaged AsciiDoc
+distribution or if you prefer to install the latest AsciiDoc version
+from source, use the `configure` shell script in the tarball root
+directory.
+
+The `autoconf(1)`-generated `configure` script creates a `Makefile`
+that is tailored for your system. To install:
+
+subs="attributes"
+  $ tar -xzf asciidoc-{revnumber}.tar.gz
+  $ cd asciidoc-{revnumber}
+  $ ./configure
+  $ sudo make install
+
+To install the documentation:
+
+  $ sudo make docs
+
+To uninstall AsciiDoc:
+
+  $ sudo make uninstall
+
+If Vim is installed on your system the AsciiDoc Vim syntax highlighter
+and filetype detection are already installed as built into the vim runtime.
+
+
+X3
+Microsoft Windows installation
+------------------------------
+AsciiDoc is developed and tested on Linux but there seem to be quite a
+few people using it on Windows. To install AsciiDoc on Windows unzip
+the distribution zip file contents:
+
+subs="attributes"
+  $ unzip asciidoc-{revnumber}.zip
+
+This will create the folder +asciidoc-{revnumber}+ containing the
+`asciidoc.py` and `a2x.py` executables along with configuration files
+and documentation.
+
+To generate DocBook based outputs (e.g. PDFs) you will also need a
+working DocBook toolchain. Installing and configuring a DocBook
+toolchain on Windows can be a challenge -- this blog post explains
+http://blog.rainwebs.net/2010/02/25/how-to-create-handsome-pdf-documents-without-frustration/How
+to Create Handsome PDF Documents Without Frustration using
+http://www.cygwin.com/Cygwin,
+http://dblatex.sourceforge.net/dblatex and AsciiDoc.
+
+
+Testing your installation
+-------------------------
+To test out AsciiDoc.py, you will need to install `pytest` and `pytest-mock`
+from PyPI.
+
+Test out asciidoc by changing to the AsciiDoc application directory
+and converting the User Guide document (`./doc/asciidoc.txt`) to XHTML
+(`./doc/asciidoc.html`):
+
+  $ python3 asciidoc.py doc/asciidoc.txt
+
+The link:testasciidoc.htmltestasciidoc tool offers a more extensive set of
+conformance tests. You can run the tests by executing this command:
+
+  $ python3 ./tests/testasciidoc.py run
+
+Unit tests can be run by doing:
+
+  $ python3 -m pytest
+
+Doctests can be run by doing:
+
+  $ python3 -m asciidoc.asciidoc --doctest
+
+Running all three of these can be accomplished through the Makefile:
+
+  $ make test
+
+
+X2
+Prepackaged AsciiDoc installation
+---------------------------------
+The following platform-specific AsciiDoc packages are available:
+
+*Fedora Linux*::
+  AsciiDoc is included in Fedora Extras, which is available in
+  the default Fedora installation. To install asciidoc, execute the
+  following command:
+
+  $ yum install asciidoc
+
+*Ubuntu / Debian*::
+  AsciiDoc is included in Ubuntu / Debian package manager. To install,
+  execute the following command:
+
+  $ apt install asciidoc
+
+*macOS Homebrew*::
+  AsciiDoc has been packaged in homebrew and is installable using the
+  following command:
+
+  $ brew install asciidoc
+
+See also link:userguide.html#X38Packager Notes in the 'AsciiDoc User

+AsciiDoc.py
+===========
+
+!Build Status(https://github.com/asciidoc/asciidoc-py3/workflows/Test/badge.svg?branch=master)(https://github.com/asciidoc/asciidoc-py3/actions?query=workflow%3ATest+branch%3Amaster)

+!PyPI version(https://badge.fury.io/py/asciidoc.svg)(https://badge.fury.io/py/asciidoc)
+
+AsciiDoc is a text document format for writing notes, documentation,
+articles, books, ebooks, slideshows, web pages, man pages and blogs.
+AsciiDoc files can be translated to many formats including HTML, PDF,
+EPUB, man page.
+
+AsciiDoc.py is a legacy processor for this syntax, handling an older
+rendition of AsciiDoc. As such, this will not properly handle the
+current AsciiDoc specification(https://projects.eclipse.org/projects/technology.asciidoc).
+It is suggested that unless you specifically require the AsciiDoc.py
+toolchain, you should find a processor that handles the modern AsciiDoc
+syntax.
+
+AsciiDoc.py is highly configurable: both the AsciiDoc source file syntax
+and the backend output markups (which can be almost any type of
+SGML/XML markup) can be customized and extended by the user.
+
+## Prerequisites
+
+AsciiDoc.py is written in Python so you need a Python interpreter
+(version 3.5 or later) to execute asciidoc(1). You can install Python using the
+package manager for your OS or by downloading it from the official Python
+website http://www.python.org.
+
+Additionally, you will need:
+
+* DocBook XSL Stylesheets 1.76.1
+* xsltproc (libxml 20706, libxslt 10126 and libexslt 815).
+* w3m 0.5.2
+* dblatex 0.3
+* FOP 0.95
+
+to enable the full AsciiDoc.py toolchain.
+
+## Obtaining AsciiDoc.py
+
+Documentation and installation instructions are on the AsciiDoc.py website
+https://asciidoc.org/. Simply, you should use use pip to install it:
+
+```
+pip3 install asciidoc
+```
+
+## Contributing
+
+To contribute and test your changes, you will need to install:
+* flake8
+* pytest
+* pytest-mock
+
+To lint the codebase: `python3 -m flake8`
+
+AsciiDoc.py has the following types of tests:
+1. doctests: `python3 -m asciidoc.asciidoc --doctest`
+1. unit tests: `python3 -m pytest`
+1. integration tests: `python3 tests/testasciidoc.py`

+NAME
+    code-filter - AsciiDoc filter to highlight language keywords
+
+SYNOPSIS
+    code-filter -b backend -l language  -t tabsize 
+                 --help | -h   --version | -v 
+
+DESCRIPTION
+    This filter reads source code from the standard input, highlights language
+    keywords and comments and writes to the standard output.
+
+    The purpose of this program is to demonstrate how to write an AsciiDoc
+    filter -- it's much to simplistic to be passed off as a code syntax
+    highlighter. Use the 'source-highlight-filter' instead.
+
+
+OPTIONS
+    --help, -h
+        Print this documentation.
+
+    -b
+        Backend output file format: 'docbook', 'linuxdoc', 'html', 'css'.
+
+    -l
+        The name of the source code language: 'python', 'ruby', 'c++', 'c'.
+
+    -t tabsize
+        Expand source tabs to tabsize spaces.
+
+    --version, -v
+        Print program version number.
+
+BUGS
+    - Code on the same line as a block comment is treated as comment.
+      Keywords inside literal strings are highlighted.
+    - There doesn't appear to be an easy way to accommodate linuxdoc so
+      just pass it through without markup.

+NAME
+    latex2img - Converts LaTeX source to PNG or SVG file
+
+SYNOPSIS
+    latex2img options INFILE
+
+DESCRIPTION
+    This filter reads LaTeX source text from the input file
+    INFILE (or stdin if INFILE is -) and renders it to PNG image file.
+    Typically used to render math equations.
+
+    Requires latex(1), dvipng(1) and/or dvisvgm(1) commands and LaTeX math
+    packages.
+
+OPTIONS
+    -D DPI
+        Set the output resolution for PNG images to DPI dots per inch. Use
+        this option to scale the output PNG image size.
+
+    -o OUTFILE
+        The file name of the output file. If not specified the output file is
+        named like INFILE but with an extension matching the chosen output
+        image format, .png for PNG images and .svg for SVG images.
+
+    -m
+        Skip if the output image file is newer than the INFILE.
+        Compares timestamps on INFILE and OUTFILE. If
+        INFILE is - (stdin) then compares MD5 checksum stored in file
+        named like OUTFILE but with a .md5 file name extension.
+        The .md5 file is created if the -m option is used and the
+        INFILE is - (stdin).
+
+    -v
+        Verbosely print processing information to stderr.
+
+    --help, -h
+        Print this documentation.
+
+    --version
+        Print program version number.

+
+    This script is a wrapper for LilyPond and ImageMagick commands.
+
+OPTIONS
+    -f FORMAT
+        The INFILE music format. 'abc' for ABC notation, 'ly' for LilyPond
+        notation. Defaults to 'abc' unless source starts with backslash.
+
+    -o OUTFILE
+        The file name of the output file. If not specified the output file is
+        named like INFILE but with a .png file name extension.
+
+    -m
+        Skip if the PNG output file is newer that than the INFILE.
+        Compares timestamps on INFILE and OUTFILE. If

+NAME
+
+   asciidoc - converts an AsciiDoc text file to HTML or DocBook
+
+SYNOPSIS
+
+   asciidoc OPTIONS FILE
+
+DESCRIPTION
+
+   The asciidoc(1) command translates the AsciiDoc text file FILE to
+   DocBook or HTML. If FILE is - then the standard input is used.
+
+OPTIONS
+
+   -a, --attribute=ATTRIBUTE
+          Define or delete document attribute. ATTRIBUTE is formatted like
+          NAME=VALUE. Command-line attributes take precedence over
+          document and configuration file attributes. Alternate acceptable
+          forms are NAME (the VALUE defaults to an empty string); NAME!
+          (delete the NAME attribute); NAME=VALUE@ (do not override
+          document or configuration file attributes). Values containing
+          spaces should be enclosed in double-quote characters. This
+          option may be specified more than once. A special attribute
+          named trace controls the output of diagnostic information.
+
+   -b, --backend=BACKEND
+          Backend output file format: docbook45, xhtml11, html4, html5,
+          slidy, wordpress or latex (the latex backend is experimental).
+          You can also use the backend alias names html (aliased to
+          xhtml11) or docbook (aliased to docbook45). Defaults to
+          html. The --backend option is also used to manage backend
+          plugins (see 1PLUGIN COMMANDS).
+
+   -f, --conf-file=CONF_FILE
+          Use configuration file CONF_FILE.Configuration files processed
+          in command-line order (after implicit configuration files). This
+          option may be specified more than once.
+
+   --doctest
+          Run Python doctests in asciidoc module.
+
+   -d, --doctype=DOCTYPE
+          Document type: article, manpage or book. The book document type
+          is only supported by the docbook backend. Default document type
+          is article.
+
+   -c, --dump-conf
+          Dump configuration to stdout.
+
+   --filter=FILTER
+          Specify the name of a filter to be loaded (used to load filters
+          that are not auto-loaded). This option may be specified more
+          than once. The --filter option is also used to manage filter
+          plugins (see 2PLUGIN COMMANDS).
+
+   -h, --help TOPIC
+          Print help TOPIC. --help topics will print a list of help
+          topics, --help syntax summarizes AsciiDoc syntax, --help manpage
+          prints the AsciiDoc manpage.
+
+   -e, --no-conf
+          Exclude implicitly loaded configuration files except for those
+          named like the input file (infile.conf and infile-backend.conf).
+
+   -s, --no-header-footer
+          Suppress document header and footer output.
+
+   -o, --out-file=OUT_FILE
+          Write output to file OUT_FILE. Defaults to the base name of
+          input file with backend extension. If the input is stdin then
+          the outfile defaults to stdout. If OUT_FILE is - then the
+          standard output is used.
+
+   -n, --section-numbers
+          Auto-number HTML article section titles. Synonym for --attribute
+          numbered.
+
+   --safe
+          Enable safe mode. Safe mode is disabled by default. AsciiDoc
+          safe mode skips potentially dangerous scripted sections in
+          AsciiDoc source files.
+
+   --theme=THEME
+          Specify a theme name. Synonym for --attribute theme=THEME. The
+          --theme option is also used to manage theme plugins (see
+          3PLUGIN COMMANDS).
+
+   -v, --verbose
+          Verbosely print processing information and configuration file
+          checks to stderr.
+
+   --version
+          Print program version number.
+
+PLUGIN COMMANDS
+
+   The asciidoc(1) --filter, --backend and --theme options are used to
+   install, remove and list AsciiDoc filter, backend and theme plugins.
+   Syntax:
+
+          asciidoc OPTION install ZIP_FILE PLUGINS_DIR
+          asciidoc OPTION remove PLUGIN_NAME PLUGINS_DIR
+          asciidoc OPTION list
+          asciidoc OPTION build ZIP_FILE PLUGIN_SOURCE
+
+   Where:
+
+   OPTION
+          asciidoc(1) --filter, --backend or --theme option specifying the
+          type of plugin.
+
+   PLUGIN_NAME
+          A unique plugin name containing only alphanumeric or underscore
+          characters.
+
+   ZIP_FILE
+          A Zip file containing plugin resources, the name must start with
+          the plugin name e.g. my_filter-1.0.zip packages filter
+          my_filter.
+
+   PLUGINS_DIR
+          The directory containing installed plugins. Each plugin is
+          contained in its own separate subdirectory which has the same
+          name as the plugin. PLUGINS_DIR defaults to the
+          $HOME/.asciidoc/filters (for filter plugins) or
+          $HOME/.asciidoc/backends (for backend plugins) or
+          $HOME/.asciidoc/themes (for theme plugins).
+
+   PLUGIN_SOURCE
+          The name of a directory containing the plugin source files or
+          the name of a single source file.
+
+   The plugin commands perform as follows:
+
+   install
+          Create a subdirectory in PLUGINS_DIR with the same name as the
+          plugin then extract the ZIP_FILE into it.
+
+   remove
+          Delete the PLUGIN_NAME plugin subdirectory and all its contents
+          from the PLUGINS_DIR.
+
+   list
+          List the names and locations of all installed filter or theme
+          plugins (including standard plugins installed in the global
+          configuration directory).
+
+   build
+          Create a plugin file named ZIP_FILE containing the files and
+          subdirectories specified by PLUGIN_SOURCE. File and directory
+          names starting with a period are skipped.
+
+EXIT STATUS
+
+   0
+          Success
+
+   1
+          Failure (syntax or usage error; configuration error; document
+          processing failure; unexpected error).

+ASCIIMath Formulae
+====================
+
+http://asciimath.org/ASCIIMath is a clever JavaScript written by
+Peter Jipsen that dynamically transforms mathematical formulae
+written in a wiki-like plain text markup to
+https://www.w3.org/Math/MathML markup which is displayed as
+standard mathematical notation by the Web Browser.  See 'Appendix E'
+in the AsciiDoc User Guide for more details.
+
+The AsciiDoc `xhtml11` backend supports ASCIIMath -- it links the
+ASCIIMath script and escapes ASCIIMath delimiters and special
+characters to yield valid XHTML. To use ASCIIMath:
+
+1. Include the `-a asciimath` command-line option when you run
+   `asciidoc(1)`.
+2. Enclose ASCIIMath formulas inside math or double-dollar
+   passthroughs or in math passthrough blocks.
+
+Here's the link:asciimath.txtAsciiDoc source that generated this
+page.
+
+.NOTE
+- When you use the `asciimath:` inline macro you need to escape ``
+  characters in the formulas with a backslash, escaping is unnecessary
+  if you use the double-dollar macro (for examples see the second
+  formula below).
+- See the http://asciimath.orgASCIIMath website for ASCIIMath
+  documentation and the latest version.
+- If the formulas don't appear to be correct you probably need to
+  install the correct math fonts (see the
+  http://asciimath.orgASCIIMath website for details).
+- See the link:latexmathml.htmlLaTeXMathML page if you prefer to use
+  LaTeX math formulas.
+
+A list of example formulas:
+
+- $$`a,b,c,d((n),(k))`$$
+- asciimath:x/x={(1,if x!=0),(text{undefined},if x=0):}
+- asciimath:d/dxf(x)=lim_(h->0)(f(x+h)-f(x))/h
+- +++`sum_(i=1)\^n i=(n(n+1))/2`$+++ and *bold
+  asciimath:int_0\^(pi/2) sinx\ dx=1*
+- asciimath:(a,b\={x in RR : a < x <= b}
+- asciimath:x^2+y_1+z_12^34
+
+*********************************************************************
+The first three terms factor to give
+asciimath:(x+b/(2a))^2=(b^2)/(4a^2)-c/a.
+
+asciimath:x+b/(2a)=+-sqrt((b^2)/(4a^2)-c/a).
+
+Now we take square roots on both sides and get
+asciimath:x+b/(2a)=+-sqrt((b^2)/(4a^2)-c/a).
+Finally we move the asciimath:b/(2a) to the right and simplify to
+get the two solutions:
+*asciimath:x_(1,2)=(-b+-sqrt(b^2-4ac))/(2a)*.

+This file contains JavaScript functions to convert ASCII math notation
+to Presentation MathML. The conversion is done while the (X)HTML page
+loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet
+Explorer 6+MathPlayer (http://www.dessci.com/en/products/mathplayer/).
+Just add the next line to your (X)HTML page with this file in the same folder:
+This is a convenient and inexpensive solution for authoring MathML.

+<div class="paragraph"><p><a href="http://asciimath.org/">ASCIIMath</a> is a clever JavaScript written by
+Peter Jipsen that dynamically transforms mathematical formulae
+written in a wiki-like plain text markup to
+<a href="https://www.w3.org/Math/">MathML</a> markup which is displayed as
+standard mathematical notation by the Web Browser.  See <em>Appendix E</em>
+in the AsciiDoc User Guide for more details.</p></div>
+<div class="paragraph"><p>The AsciiDoc <span class="monospaced">xhtml11</span> backend supports ASCIIMath&#8201;&#8212;&#8201;it links the

+<li>
+<p>
+Include the <span class="monospaced">-a asciimath</span> command-line option when you run

+</p>
+</li>
+<li>
+<p>
+Enclose ASCIIMath formulas inside math or double-dollar

+<p>
+When you use the <span class="monospaced">asciimath:</span> inline macro you need to escape <span class="monospaced"></span>

+If the formulas don&#8217;t appear to be correct you probably need to

+ASCIIMathML.js
+==============
+This file contains JavaScript functions to convert ASCII math notation
+to Presentation MathML. The conversion is done while the (X)HTML page
+loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet
+Explorer 6+MathPlayer (http://www.dessci.com/en/products/mathplayer/).
+Just add the next line to your (X)HTML page with this file in the same folder:
+This is a convenient and inexpensive solution for authoring MathML.

+ASCIIDOC(1)
+===========
+:doctype: manpage
+
+
+NAME
+----
+asciidoc - converts an AsciiDoc text file to HTML or DocBook
+
+
+SYNOPSIS
+--------
+*asciidoc* 'OPTIONS' 'FILE'
+
+
+DESCRIPTION
+-----------
+The asciidoc(1) command translates the AsciiDoc text file 'FILE' to
+DocBook or HTML.  If 'FILE' is '-' then the standard input is used.
+
+
+OPTIONS
+-------
+*-a, --attribute*='ATTRIBUTE'::
+    Define or delete document attribute. 'ATTRIBUTE' is formatted like
+    'NAME=VALUE'. Command-line attributes take precedence over
+    document and configuration file attributes.  Alternate acceptable
+    forms are 'NAME' (the 'VALUE' defaults to an empty string);
+    'NAME!' (delete the 'NAME' attribute); 'NAME=VALUE@' (do not override
+    document or configuration file attributes).  Values containing
+    spaces should be enclosed in double-quote characters. This option
+    may be specified more than once.  A special attribute named
+    'trace' controls the output of diagnostic information.
+
+*-b, --backend*='BACKEND'::
+    Backend output file format: 'docbook45', 'docbook5', 'xhtml11', 'html4',
+    'html5', 'slidy', 'wordpress' or 'latex' (the 'latex' backend is
+    experimental).  You can also use the backend alias names 'html'
+    (aliased to 'xhtml11') or 'docbook' (aliased to 'docbook45').
+    Defaults to 'html'.  The *--backend* option is also used to manage
+    backend plugins (see <<X1,*PLUGIN COMMANDS*>>).
+
+*-f, --conf-file*='CONF_FILE'::
+    Use configuration file 'CONF_FILE'.Configuration files processed
+    in command-line order (after implicit configuration files).  This
+    option may be specified more than once.
+
+*--doctest*::
+    Run Python doctests in 'asciidoc' module.
+
+*-d, --doctype*='DOCTYPE'::
+    Document type: 'article', 'manpage' or 'book'. The 'book' document
+    type is only supported by the 'docbook' backends.  Default document
+    type is 'article'.
+
+*-c, --dump-conf*::
+    Dump configuration to stdout.
+
+*--filter*='FILTER'::
+    Specify the name of a filter to be loaded (used to load filters
+    that are not auto-loaded).  This option may be specified more than
+    once. The *--filter* option is also used to manage filter plugins
+    (see <<X1,*PLUGIN COMMANDS*>>).
+
+*-h, --help* 'TOPIC'::
+    Print help TOPIC. *--help* 'topics' will print a list of help
+    topics, *--help* 'syntax' summarizes AsciiDoc syntax,
+    *--help* 'manpage' prints the AsciiDoc manpage.
+
+*-e, --no-conf*::
+    Exclude implicitly loaded configuration files except for those
+    named like the input file ('infile.conf' and
+    'infile-backend.conf').
+
+*-s, --no-header-footer*::
+    Suppress document header and footer output.
+
+*-o, --out-file*='OUT_FILE'::
+    Write output to file 'OUT_FILE'. Defaults to the base name of
+    input file with 'backend' extension. If the input is stdin then
+    the outfile defaults to stdout. If 'OUT_FILE' is '-' then the
+    standard output is used.
+
+*-n, --section-numbers*::
+    Auto-number HTML article section titles.  Synonym for
+    *--attribute numbered*.
+
+*--safe*::
+    Enable safe mode. Safe mode is disabled by default.  AsciiDoc
+    'safe mode' skips potentially dangerous scripted sections in
+    AsciiDoc source files.
+
+*--theme*='THEME'::
+    Specify a theme name.  Synonym for *--attribute theme*='THEME'.
+    The *--theme* option is also used to manage theme plugins (see
+    <<X1,*PLUGIN COMMANDS*>>).
+
+*-v, --verbose*::
+    Verbosely print processing information and configuration file
+    checks to stderr.
+
+*--version*::
+    Print program version number.
+
+
+X1
+PLUGIN COMMANDS
+---------------
+The asciidoc(1) *--filter*, *--backend* and *--theme* options are used
+to install, remove and list AsciiDoc filter, backend and theme
+plugins. Syntax:
+
+  asciidoc OPTION install ZIP_FILE PLUGINS_DIR
+  asciidoc OPTION remove PLUGIN_NAME PLUGINS_DIR
+  asciidoc OPTION list
+  asciidoc OPTION build ZIP_FILE PLUGIN_SOURCE
+
+Where:
+
+*OPTION*::
+  asciidoc(1) *--filter*, *--backend* or *--theme* option specifying
+  the type of plugin.
+
+*PLUGIN_NAME*::
+  A unique plugin name containing only alphanumeric or underscore
+  characters.
+
+*ZIP_FILE*::
+  A Zip file containing plugin resources, the name must start with the
+  plugin name e.g.  `my_filter-1.0.zip` packages filter `my_filter`.
+
+*PLUGINS_DIR*::
+  The directory containing installed plugins. Each plugin is contained
+  in its own separate subdirectory which has the same name as the
+  plugin.
+  *PLUGINS_DIR* defaults to the `$HOME/.asciidoc/filters` (for
+  filter plugins) or `$HOME/.asciidoc/backends` (for backend plugins) or
+  `$HOME/.asciidoc/themes` (for theme plugins).
+
+*PLUGIN_SOURCE*::
+  The name of a directory containing the plugin source files or the
+  name of a single source file.
+
+The plugin commands perform as follows:
+
+*install*::
+  Create a subdirectory in *PLUGINS_DIR* with the same name as the
+  plugin then extract the *ZIP_FILE* into it.
+
+*remove*::
+  Delete the *PLUGIN_NAME* plugin subdirectory and all its contents
+  from the *PLUGINS_DIR*.
+
+*list*::
+  List the names and locations of all installed filter or theme
+  plugins (including standard plugins installed in the global
+  configuration directory).
+
+*build*::
+  Create a plugin file named *ZIP_FILE* containing the files and
+  subdirectories specified by *PLUGIN_SOURCE*. File and directory
+  names starting with a period are skipped.
+
+
+ENVIRONMENT VARIABLES
+---------------------
+
+*`SOURCE_DATE_EPOCH`*::
+  If the `SOURCE_DATE_EPOCH` environment variable is set to a UNIX
+  timestamp, then the `{docdate}`, `{doctime}`, `{localdate}`, and
+  `{localtime}` attributes are computed in the UTC time zone, with any
+  timestamps newer than `SOURCE_DATE_EPOCH` replaced by
+  `SOURCE_DATE_EPOCH`. (This helps software using AsciiDoc to build
+  reproducibly.)
+
+
+EXAMPLES
+--------
+`asciidoc asciidoc_file_name.txt`::
+  Simply generate an html file from the asciidoc_file_name.txt that is in
+  current directory using asciidoc.
+
+`asciidoc -b html5 asciidoc_file_name.txt`::
+  Use the `-b` switch to use one of the proposed backend or another one you
+  installed on your computer.
+
+`asciidoc -a data-uri -a icons -a toc -a max-width=55em article.txt`::
+  Use the `-a` switch to set attributes from command-line. AsciiDoc generated
+  its stand-alone HTML user guide containing embedded CSS, JavaScript and
+  images from the AsciiDoc article template with this command.
+
+`asciidoc -b html5 -d manpage asciidoc.1.txt`::
+  Generating the asciidoc manpage using the html5 backend.
+
+
+EXIT STATUS
+-----------

+AsciiDoc User Guide
+===================
+AsciiDoc.py Team
+:toc:
+:icons:
+:numbered:
+:website: https://asciidoc.org/
+
+AsciiDoc is a text document format for writing notes, documentation,
+articles, books, ebooks, slideshows, web pages, blogs and UNIX man
+pages.  AsciiDoc files can be translated to many formats including
+HTML, PDF, EPUB, man page.  AsciiDoc is highly configurable: both the
+AsciiDoc source file syntax and the backend output markups (which can
+be almost any type of SGML/XML markup) can be customized and extended
+by the user.
+
+WARNING
+This user guide is for AsciiDoc.py, which is a legacy processor for
+this syntax, handling an older rendition of AsciiDoc. As such, this
+will not properly handle the
+https://projects.eclipse.org/projects/technology.asciidoccurrent AsciiDoc specification.
+It is suggested that unless you specifically require the AsciiDoc.py
+toolchain, you should find a processor that handles the modern
+AsciiDoc syntax.
+
+.This document
+**********************************************************************
+This is an overly large document, it probably needs to be refactored
+into a Tutorial, Quick Reference and Formal Reference.
+
+If you're new to AsciiDoc read this section and the <<X6,Getting
+Started>> section and take a look at the example AsciiDoc (`*.txt`)
+source files in the distribution `doc` directory.
+**********************************************************************
+
+
+Introduction
+------------
+AsciiDoc is a plain text human readable/writable document format that
+can be translated to DocBook or HTML using the asciidoc(1) command.
+You can then either use asciidoc(1) generated HTML directly or run
+asciidoc(1) DocBook output through your favorite DocBook toolchain or
+use the AsciiDoc a2x(1) toolchain wrapper to produce PDF, EPUB, DVI,
+LaTeX, PostScript, man page, HTML and text formats.
+
+The AsciiDoc format is a useful presentation format in its own right:
+AsciiDoc markup is simple, intuitive and as such is easily proofed and
+edited.
+
+AsciiDoc is light weight: it consists of a single Python script and a
+bunch of configuration files. Apart from asciidoc(1) and a Python
+interpreter, no other programs are required to convert AsciiDoc text
+files to DocBook or HTML. See <<X11,Example AsciiDoc Documents>>
+below.
+
+Text markup conventions tend to be a matter of (often strong) personal
+preference: if the default syntax is not to your liking you can define
+your own by editing the text based asciidoc(1) configuration files.
+You can also create configuration files to translate AsciiDoc
+documents to almost any SGML/XML markup.
+
+asciidoc(1) comes with a set of configuration files to translate
+AsciiDoc articles, books and man pages to HTML or DocBook backend
+formats.
+
+.My AsciiDoc Itch
+**********************************************************************
+DocBook has emerged as the de facto standard Open Source documentation
+format. But DocBook is a complex language, the markup is difficult to
+read and even more difficult to write directly -- I found I was
+spending more time typing markup tags, consulting reference manuals
+and fixing syntax errors, than I was writing the documentation.
+**********************************************************************
+
+
+X6
+Getting Started
+---------------
+Installing AsciiDoc
+~~~~~~~~~~~~~~~~~~~
+See the `README` and `INSTALL` files for install prerequisites and
+procedures. Packagers take a look at <<X38,Packager Notes>>.
+
+X11
+Example AsciiDoc Documents
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+The best way to quickly get a feel for AsciiDoc is to view the
+AsciiDoc web site and/or distributed examples:
+
+- Take a look at the linked examples on the AsciiDoc web site home
+  page {website}.  Press the 'Page Source' sidebar menu item to view
+  corresponding AsciiDoc source.
+- Read the `*.txt` source files in the distribution `./doc` directory
+  along with the corresponding HTML and DocBook XML files.
+
+
+AsciiDoc Document Types
+-----------------------
+There are three types of AsciiDoc documents: article, book and
+manpage. All document types share the same AsciiDoc format with some
+minor variations. If you are familiar with DocBook you will have
+noticed that AsciiDoc document types correspond to the same-named
+DocBook document types.
+
+Use the asciidoc(1) `-d` (`--doctype`) option to specify the AsciiDoc
+document type -- the default document type is 'article'.
+
+By convention the `.txt` file extension is used for AsciiDoc document
+source files.
+
+article
+~~~~~~~
+Used for short documents, articles and general documentation.  See the
+AsciiDoc distribution `./doc/article.txt` example.
+
+AsciiDoc defines standard DocBook article frontmatter and backmatter
+<<X93,section markup templates>> (appendix, abstract, bibliography,
+glossary, index).
+
+book
+~~~~
+Books share the same format as articles, with the following
+differences:
+
+- The part titles in multi-part books are <<X17,top level titles>>
+  (same level as book title).
+- Some sections are book specific e.g. preface and colophon.
+
+Book documents will normally be used to produce DocBook output since
+DocBook processors can automatically generate footnotes, table of
+contents, list of tables, list of figures, list of examples and
+indexes.
+
+AsciiDoc defines standard DocBook book frontmatter and backmatter
+<<X93,section markup templates>> (appendix, dedication, preface,
+bibliography, glossary, index, colophon).
+
+.Example book documents
+Book::
+  The `./doc/book.txt` file in the AsciiDoc distribution.
+
+Multi-part book::
+  The `./doc/book-multi.txt` file in the AsciiDoc distribution.
+
+manpage
+~~~~~~~
+Used to generate roff format UNIX manual pages.  AsciiDoc manpage
+documents observe special header title and section naming conventions
+-- see the <<X1,Manpage Documents>> section for details.
+
+AsciiDoc defines the 'synopsis' <<X93,section markup template>> to
+generate the DocBook `refsynopsisdiv` section.
+
+See also the asciidoc(1) man page source (`./doc/asciidoc.1.txt`) from
+the AsciiDoc distribution.
+
+
+X5
+AsciiDoc Backends
+-----------------
+The asciidoc(1) command translates an AsciiDoc formatted file to the
+backend format specified by the `-b` (`--backend`) command-line
+option. asciidoc(1) itself has little intrinsic knowledge of backend
+formats, all translation rules are contained in customizable cascading
+configuration files. Backend specific attributes are listed in the
+<<X88,Backend Attributes>> section.
+
+docbook45::
+  Outputs DocBook XML 4.5 markup.
+
+docbook5::
+  Outputs DocBook XML 5.0 markup.
+
+html4::
+  This backend generates plain HTML 4.01 Transitional markup.
+
+xhtml11::
+  This backend generates XHTML 1.1 markup styled with CSS2. Output
+  files have an `.html` extension.
+
+html5::
+  This backend generates HTML 5 markup, apart from the inclusion of
+  <<X98,audio and video block macros>> it is functionally identical to
+  the 'xhtml11' backend.
+
+slidy::
+  Use this backend to generate self-contained
+  https://www.w3.org/Talks/Tools/Slidy2Slidy HTML slideshows for
+  your web browser from AsciiDoc documents. The Slidy backend is
+  documented in the distribution `doc/slidy.txt` file and
+  {website}slidy.htmlonline.
+
+wordpress::
+  A minor variant of the 'html4' backend to support
+  https://srackham.wordpress.com/blogpost1/blogpost.
+
+latex::
+  Experimental LaTeX backend.
+
+Backend Aliases
+~~~~~~~~~~~~~~~
+Backend aliases are alternative names for AsciiDoc backends.  AsciiDoc
+comes with two backend aliases: 'html' (aliased to 'xhtml11') and
+'docbook' (aliased to 'docbook45').
+
+You can assign (or reassign) backend aliases by setting an AsciiDoc
+attribute named like `backend-alias-<alias>` to an AsciiDoc backend
+name. For example, the following backend alias attribute definitions
+appear in the `attributes` section of the global `asciidoc.conf`
+configuration file:
+
+  backend-alias-html=xhtml11
+  backend-alias-docbook=docbook45
+
+X100
+Backend Plugins
+~~~~~~~~~~~~~~~
+The asciidoc(1) `--backend` option is also used to install and manage
+backend <<X101,plugins>>.
+
+- A backend plugin is used just like the built-in backends.
+- Backend plugins <<X27,take precedence>> over built-in backends with
+  the same name.
+- You can use the `{asciidoc-confdir}` <<X60, intrinsic attribute>> to
+  refer to the built-in backend configuration file location from
+  backend plugin configuration files.
+- You can use the `{backend-confdir}` <<X60, intrinsic attribute>> to
+  refer to the backend plugin configuration file location.
+- By default backends plugins are installed in
+  `$HOME/.asciidoc/backends/<backend>` where `<backend>` is the
+  backend name.
+
+
+DocBook
+-------
+AsciiDoc generates 'article', 'book' and 'refentry'
+https://docbook.org/DocBook documents (corresponding to the
+AsciiDoc 'article', 'book' and 'manpage' document types).
+
+Most Linux distributions come with conversion tools (collectively
+called a toolchain) for <<X12,converting DocBook files>> to
+presentation formats such as Postscript, HTML, PDF, EPUB, DVI,
+PostScript, LaTeX, roff (the native man page format), HTMLHelp,
+JavaHelp and text.  There are also programs that allow you to view
+DocBook files directly, for example
+https://wiki.gnome.org/action/show/Apps/YelpYelp (the GNOME help
+viewer).
+
+X12
+Converting DocBook to other file formats
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+DocBook files are validated, parsed and translated various
+presentation file formats using a combination of applications
+collectively called a DocBook 'tool chain'. The function of a tool
+chain is to read the DocBook markup (produced by AsciiDoc) and
+transform it to a presentation format (for example HTML, PDF, HTML
+Help, EPUB, DVI, PostScript, LaTeX).
+
+A wide range of user output format requirements coupled with a choice
+of available tools and stylesheets results in many valid tool chain
+combinations.
+
+X43
+a2x Toolchain Wrapper
+~~~~~~~~~~~~~~~~~~~~~
+One of the biggest hurdles for new users is installing, configuring
+and using a DocBook XML toolchain. `a2x(1)` can help -- it's a
+toolchain wrapper command that will generate XHTML (chunked and
+unchunked), PDF, EPUB, DVI, PS, LaTeX, man page, HTML Help and text
+file outputs from an AsciiDoc text file.  `a2x(1)` does all the grunt
+work associated with generating and sequencing the toolchain commands
+and managing intermediate and output files.  `a2x(1)` also optionally
+deploys admonition and navigation icons and a CSS stylesheet. See the
+`a2x(1)` man page for more details. In addition to `asciidoc(1)` you
+also need <<X40,xsltproc(1)>>, <<X13,DocBook XSL Stylesheets>> and
+optionally: <<X31,dblatex>> or <<X14,FOP>> (to generate PDF);
+`w3m(1)` or `lynx(1)` (to generate text).
+
+The following examples generate `doc/source-highlight-filter.pdf` from
+the AsciiDoc `doc/source-highlight-filter.txt` source file. The first
+example uses `dblatex(1)` (the default PDF generator) the second
+example forces FOP to be used:
+
+  $ a2x -f pdf doc/source-highlight-filter.txt
+  $ a2x -f pdf --fop doc/source-highlight-filter.txt
+
+See the `a2x(1)` man page for details.
+
+TIP: Use the `--verbose` command-line option to view executed
+toolchain commands.
+
+HTML generation
+~~~~~~~~~~~~~~~
+AsciiDoc produces nicely styled HTML directly without requiring a
+DocBook toolchain but there are also advantages in going the DocBook
+route:
+
+- HTML from DocBook can optionally include automatically generated
+  indexes, tables of contents, footnotes, lists of figures and tables.
+- DocBook toolchains can also (optionally) generate separate (chunked)
+  linked HTML pages for each document section.
+- Toolchain processing performs link and document validity checks.
+- If the DocBook 'lang' attribute is set then things like table of
+  contents, figure and table captions and admonition captions will be
+  output in the specified language (setting the AsciiDoc 'lang'
+  attribute sets the DocBook 'lang' attribute).
+
+On the other hand, HTML output directly from AsciiDoc is much faster,
+is easily customized and can be used in situations where there is no
+suitable DocBook toolchain (for example, see the {website}AsciiDoc
+website).
+
+PDF generation
+~~~~~~~~~~~~~~
+There are two commonly used tools to generate PDFs from DocBook,
+<<X31,dblatex>> and <<X14,FOP>>.
+
+.dblatex or FOP?
+- 'dblatex' is easier to install, there's zero configuration
+  required and no Java VM to install -- it just works out of the box.
+- 'dblatex' source code highlighting and numbering is superb.
+- 'dblatex' is easier to use as it converts DocBook directly to PDF
+  whereas before using 'FOP' you have to convert DocBook to XML-FO
+  using <<X13,DocBook XSL Stylesheets>>.
+- 'FOP' is more feature complete (for example, callouts are processed
+  inside literal layouts) and arguably produces nicer looking output.
+
+HTML Help generation
+~~~~~~~~~~~~~~~~~~~~
+. Convert DocBook XML documents to HTML Help compiler source files
+  using <<X13,DocBook XSL Stylesheets>> and <<X40,xsltproc(1)>>.
+. Convert the HTML Help source (`.hhp` and `.html`) files to HTML Help
+  (`.chm`) files using the <<X67,Microsoft HTML Help Compiler>>.
+
+Toolchain components summary
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+AsciiDoc::
+    Converts AsciiDoc (`.txt`) files to DocBook XML (`.xml`) files.
+
+X13https://github.com/docbook/xslt10-stylesheetsDocBook XSLT Stylesheets::
+  These are a set of XSL stylesheets containing rules for converting
+  DocBook XML documents to HTML, XSL-FO, manpage and HTML Help files.
+  The stylesheets are used in conjunction with an XML parser such as
+  <<X40,xsltproc(1)>>.
+
+X40http://www.xmlsoft.orgxsltproc::
+  An XML parser for applying XSLT stylesheets (in our case the
+  <<X13,DocBook XSL Stylesheets>>) to XML documents.
+
+X31http://dblatex.sourceforge.net/dblatex::
+  Generates PDF, DVI, PostScript and LaTeX formats directly from
+  DocBook source via the intermediate LaTeX typesetting language --
+  uses <<X13,DocBook XSL Stylesheets>>, <<X40,xsltproc(1)>> and
+  `latex(1)`.
+
+X14https://xmlgraphics.apache.org/fop/FOP::
+  The Apache Formatting Objects Processor converts XSL-FO (`.fo`)
+  files to PDF files.  The XSL-FO files are generated from DocBook
+  source files using <<X13,DocBook XSL Stylesheets>> and
+  <<X40,xsltproc(1)>>.
+
+X67Microsoft Help Compiler::
+  The Microsoft HTML Help Compiler (`hhc.exe`) is a command-line tool
+  that converts HTML Help source files to a single HTML Help (`.chm`)
+  file. It runs on MS Windows platforms and can be downloaded from
+  https://www.microsoft.com/.
+
+AsciiDoc dblatex configuration files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The AsciiDoc distribution `./dblatex` directory contains
+`asciidoc-dblatex.xsl` (customized XSL parameter settings) and
+`asciidoc-dblatex.sty` (customized LaTeX settings). These are examples
+of optional <<X31,dblatex>> output customization and are used by
+<<X43,a2x(1)>>.
+
+AsciiDoc DocBook XSL Stylesheets drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You will have noticed that the distributed HTML and HTML Help
+documentation files (for example `./doc/asciidoc.html`) are not the
+plain outputs produced using the default 'DocBook XSL Stylesheets'
+configuration.  This is because they have been processed using
+customized DocBook XSL Stylesheets along with (in the case of HTML
+outputs) the custom `./stylesheets/docbook-xsl.css` CSS stylesheet.
+
+You'll find the customized DocBook XSL drivers along with additional
+documentation in the distribution `./docbook-xsl` directory. The
+examples that follow are executed from the distribution documentation
+(`./doc`) directory. These drivers are also used by <<X43,a2x(1)>>.
+
+`common.xsl`::
+    Shared driver parameters.  This file is not used directly but is
+    included in all the following drivers.
+
+`chunked.xsl`::
+    Generate chunked XHTML (separate HTML pages for each document
+    section) in the `./doc/chunked` directory. For example:
+
+    $ python ../asciidoc.py -b docbook asciidoc.txt
+    $ xsltproc --nonet ../docbook-xsl/chunked.xsl asciidoc.xml
+
+`epub.xsl`::
+    Used by <<X43,a2x(1)>> to generate EPUB formatted documents.
+
+`fo.xsl`::
+    Generate XSL Formatting Object (`.fo`) files for subsequent PDF
+    file generation using FOP. For example:
+
+    $ python ../asciidoc.py -b docbook article.txt
+    $ xsltproc --nonet ../docbook-xsl/fo.xsl article.xml > article.fo
+    $ fop article.fo article.pdf
+
+`htmlhelp.xsl`::
+    Generate Microsoft HTML Help source files for the MS HTML Help
+    Compiler in the `./doc/htmlhelp` directory. This example is run on
+    MS Windows from a Cygwin shell prompt:
+
+    $ python ../asciidoc.py -b docbook asciidoc.txt
+    $ xsltproc --nonet ../docbook-xsl/htmlhelp.xsl asciidoc.xml
+    $ c:/Program\ Files/HTML\ Help\ Workshop/hhc.exe htmlhelp.hhp
+
+`manpage.xsl`::
+    Generate a `roff(1)` format UNIX man page from a DocBook XML
+    'refentry' document. This example generates an `asciidoc.1` man
+    page file:
+
+    $ python ../asciidoc.py -d manpage -b docbook asciidoc.1.txt
+    $ xsltproc --nonet ../docbook-xsl/manpage.xsl asciidoc.1.xml
+
+`xhtml.xsl`::
+    Convert a DocBook XML file to a single XHTML file. For example:
+
+    $ python ../asciidoc.py -b docbook asciidoc.txt
+    $ xsltproc --nonet ../docbook-xsl/xhtml.xsl asciidoc.xml > asciidoc.html
+
+If you want to see how the complete documentation set is processed
+take a look at the A-A-P script `./doc/main.aap`.
+
+
+Generating Plain Text Files
+---------------------------
+AsciiDoc does not have a text backend (for most purposes AsciiDoc
+source text is fine), however you can convert AsciiDoc text files to
+formatted text using the AsciiDoc <<X43,a2x(1)>> toolchain wrapper
+utility.
+
+
+X35
+HTML5 and XHTML 1.1
+-------------------
+The 'xhtml11' and 'html5' backends embed or link CSS and JavaScript
+files in their outputs, there is also a <<X99,themes>> plugin
+framework.
+
+- If the AsciiDoc 'linkcss' attribute is defined then CSS and
+  JavaScript files are linked to the output document, otherwise they
+  are embedded (the default behavior).
+- The default locations for CSS and JavaScript files can be changed by
+  setting the AsciiDoc 'stylesdir' and 'scriptsdir' attributes
+  respectively.
+- The default locations for embedded and linked files differ and are
+  calculated at different times -- embedded files are loaded when
+  asciidoc(1) generates the output document, linked files are loaded
+  by the browser when the user views the output document.
+- Embedded files are automatically inserted in the output files but
+  you need to manually copy linked CSS and Javascript files from
+  AsciiDoc <<X27,configuration directories>> to the correct location
+  relative to the output document.
+
+.Stylesheet file locations

+X99
+Themes
+~~~~~~
+The AsciiDoc 'theme' attribute is used to select an alternative CSS
+stylesheet and to optionally include additional JavaScript code.
+
+- Theme files reside in an AsciiDoc <<X27,configuration directory>>
+  named `themes/<theme>/` (where `<theme>` is the the theme name set
+  by the 'theme' attribute). asciidoc(1) sets the 'themedir' attribute
+  to the theme directory path name.
+- The 'theme' attribute can also be set using the asciidoc(1)
+  `--theme` option, the `--theme` option can also be used to manage
+  theme <<X101,plugins>>.
+- AsciiDoc ships with two themes: 'flask' and 'volnitsky'.
+- The `<theme>.css` file replaces the default `asciidoc.css` CSS file.
+- The `<theme>.js` file is included in addition to the default
+  `asciidoc.js` JavaScript file.
+- If the <<X66,data-uri>> attribute is defined then icons are loaded
+  from the theme `icons` sub-directory if it exists (i.e.  the
+  'iconsdir' attribute is set to theme `icons` sub-directory path).
+- Embedded theme files are automatically inserted in the output files
+  but you need to manually copy linked CSS and Javascript files to the
+  location of the output documents.
+- Linked CSS and JavaScript theme files are linked to the same linked
+  locations as <<X35,other CSS and JavaScript files>>.
+
+For example, the command-line option `--theme foo` (or `--attribute
+theme=foo`) will cause asciidoc(1) to search <<X27,configuration
+file locations 1, 2 and 3>> for a sub-directory called `themes/foo`
+containing the stylesheet `foo.css` and optionally a JavaScript file
+name `foo.js`.
+
+
+Document Structure
+------------------
+An AsciiDoc document consists of a series of <<X8,block elements>>
+starting with an optional document Header, followed by an optional
+Preamble, followed by zero or more document Sections.
+
+Almost any combination of zero or more elements constitutes a valid
+AsciiDoc document: documents can range from a single sentence to a
+multi-part book.
+
+Block Elements
+~~~~~~~~~~~~~~
+Block elements consist of one or more lines of text and may contain
+other block elements.
+
+The AsciiDoc block structure can be informally summarized as follows
+footnote:This is a rough structural guide, not a rigorous syntax
+definition:
+
+  Document      ::= (Header?,Preamble?,Section*)
+  Header        ::= (Title,(AuthorInfo,RevisionInfo?)?)
+  AuthorInfo    ::= (FirstName,(MiddleName?,LastName)?,EmailAddress?)
+  RevisionInfo  ::= (RevisionNumber?,RevisionDate,RevisionRemark?)
+  Preamble      ::= (SectionBody)
+  Section       ::= (Title,SectionBody?,(Section)*)
+  SectionBody   ::= ((BlockTitle?,Block)|BlockMacro)+
+  Block         ::= (Paragraph|DelimitedBlock|List|Table)
+  List          ::= (BulletedList|NumberedList|LabeledList|CalloutList)
+  BulletedList  ::= (ListItem)+
+  NumberedList  ::= (ListItem)+
+  CalloutList   ::= (ListItem)+
+  LabeledList   ::= (ListEntry)+
+  ListEntry     ::= (ListLabel,ListItem)
+  ListLabel     ::= (ListTerm+)
+  ListItem      ::= (ItemText,(List|ListParagraph|ListContinuation)*)
+
+Where:
+
+- '?' implies zero or one occurrence, '+' implies one or more
+  occurrences, '*' implies zero or more occurrences.
+- All block elements are separated by line boundaries.
+- `BlockId`, `AttributeEntry` and `AttributeList` block elements (not
+  shown) can occur almost anywhere.
+- There are a number of document type and backend specific
+  restrictions imposed on the block syntax.
+- The following elements cannot contain blank lines: Header, Title,
+  Paragraph, ItemText.
+- A ListParagraph is a Paragraph with its 'listelement' option set.
+- A ListContinuation is a <<X15,list continuation element>>.
+
+X95
+Header
+~~~~~~
+The Header contains document meta-data, typically title plus optional
+authorship and revision information:
+
+- The Header is optional, but if it is used it must start with a
+  document <<X17,title>>.
+- Optional Author and Revision information immediately follows the
+  header title.
+- The document header must be separated from the remainder of the
+  document by one or more blank lines and cannot contain blank lines.
+- The header can include comments.
+- The header can include <<X18,attribute entries>>, typically
+  'doctype', 'lang', 'encoding', 'icons', 'data-uri', 'toc',
+  'numbered'.
+- Header attributes are overridden by command-line attributes.
+- If the header contains non-UTF-8 characters then the 'encoding' must
+  precede the header (either in the document or on the command-line).
+
+Here's an example AsciiDoc document header:
+
+  Writing Documentation using AsciiDoc
+  ====================================
+  Joe Bloggs <jbloggs@mymail.com>
+  v2.0, February 2003:
+  Rewritten for version 2 release.
+
+The author information line contains the author's name optionally
+followed by the author's email address. The author's name is formatted
+like:
+
+  firstname middlename lastname <email>
+
+i.e. a first name followed by optional middle and last names followed
+by an email address in that order.  Multi-word first, middle and last
+names can be entered using the underscore as a word separator.  The
+email address comes last and must be enclosed in angle <> brackets.
+Here a some examples of author information lines:
+
+  Joe Bloggs <jbloggs@mymail.com>
+  Joe Bloggs
+  Vincent Willem van_Gogh
+
+If the author line does not match the above specification then the
+entire author line is treated as the first name.
+
+The optional revision information line follows the author information
+line. The revision information can be one of two formats:
+
+. An optional document revision number followed by an optional
+  revision date followed by an optional revision remark:
++
+--
+  * If the revision number is specified it must be followed by a
+    comma.
+  * The revision number must contain at least one numeric character.
+  * Any non-numeric characters preceding the first numeric character
+    will be dropped.
+  * If a revision remark is specified it must be preceded by a colon.
+    The revision remark extends from the colon up to the next blank
+    line, attribute entry or comment and is subject to normal text
+    substitutions.
+  * If a revision number or remark has been set but the revision date
+    has not been set then the revision date is set to the value of the
+    'docdate' attribute.
+
+Examples:
+
+  v2.0, February 2003
+  February 2003
+  v2.0,
+  v2.0, February 2003: Rewritten for version 2 release.
+  February 2003: Rewritten for version 2 release.
+  v2.0,: Rewritten for version 2 release.
+  :Rewritten for version 2 release.
+--
+
+. The revision information line can also be an RCS/CVS/SVN $Id$
+  marker:
++
+--
+  * AsciiDoc extracts the 'revnumber', 'revdate', and 'author'
+    attributes from the $Id$ revision marker and displays them in the
+    document header.
+  * If an $Id$ revision marker is used the header author line can be
+    omitted.
+
+Example:
+
+  $Id: mydoc.txt,v 1.5 2009/05/17 17:58:44 jbloggs Exp $
+--
+
+You can override or set header parameters by passing 'revnumber',
+'revremark', 'revdate', 'email', 'author', 'authorinitials',
+'firstname' and 'lastname' attributes using the asciidoc(1) `-a`
+(`--attribute`) command-line option. For example:
+
+  $ asciidoc -a revdate=2004/07/27 article.txt
+
+Attribute entries can also be added to the header for substitution in
+the header template with <<X18,Attribute Entry>> elements.
+
+The 'title' element in HTML outputs is set to the AsciiDoc document
+title, you can set it to a different value by including a 'title'
+attribute entry in the document header.
+
+X87
+Additional document header information
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+AsciiDoc has two mechanisms for optionally including additional
+meta-data in the header of the output document:
+
+'docinfo' configuration file sections::
+If a <<X7,configuration file>> section named 'docinfo' has been loaded
+then it will be included in the document header. Typically the
+'docinfo' section name will be prefixed with a '+' character so that it
+is appended to (rather than replace) other 'docinfo' sections.
+
+'docinfo' files::
+Two docinfo files are recognized: one named `docinfo` and a second
+named like the AsciiDoc source file with a `-docinfo` suffix.  For
+example, if the source document is called `mydoc.txt` then the
+document information files would be `docinfo.xml` and
+`mydoc-docinfo.xml` (for DocBook outputs) and `docinfo.html` and
+`mydoc-docinfo.html` (for HTML outputs).  The <<X97,docinfo, docinfo1
+and docinfo2>> attributes control which docinfo files are included in
+the output files.
+
+The contents docinfo templates and files is dependent on the type of
+output:
+
+HTML::
+  Valid 'head' child elements. Typically 'style' and 'script' elements
+  for CSS and JavaScript inclusion.
+
+DocBook::
+  Valid 'articleinfo' or 'bookinfo' child elements.  DocBook defines
+  numerous elements for document meta-data, for example: copyrights,
+  document history and authorship information.  See the DocBook
+  `./doc/article-docinfo.xml` example that comes with the AsciiDoc
+  distribution.  The rendering of meta-data elements (or not) is
+  DocBook processor dependent.
+
+
+X86
+Preamble
+~~~~~~~~
+The Preamble is an optional untitled section body between the document
+Header and the first Section title.
+
+Sections
+~~~~~~~~
+In addition to the document title (level 0), AsciiDoc supports four
+section levels: 1 (top) to 4 (bottom).  Section levels are delimited
+by section <<X17,titles>>.  Sections are translated using
+configuration file <<X93,section markup templates>>. AsciiDoc
+generates the following <<X60,intrinsic attributes>> specifically for
+use in section markup templates:
+
+level::
+The `level` attribute is the section level number, it is normally just
+the <<X17,title>> level number (1..4). However, if the `leveloffset`
+attribute is defined it will be added to the `level` attribute. The
+`leveloffset` attribute is useful for <<X90,combining documents>>.
+
+sectnum::
+The `-n` (`--section-numbers`) command-line option generates the
+`sectnum` (section number) attribute.  The `sectnum` attribute is used
+for section numbers in HTML outputs (DocBook section numbering are
+handled automatically by the DocBook toolchain commands).
+
+X93
+Section markup templates
+^^^^^^^^^^^^^^^^^^^^^^^^
+Section markup templates specify output markup and are defined in
+AsciiDoc configuration files.  Section markup template names are
+derived as follows (in order of precedence):
+
+1. From the title's first positional attribute or 'template'
+   attribute. For example, the following three section titles are
+   functionally equivalent:
++
+.....................................................................
+terms
+glossary
+List of Terms
+-------------
+
+"glossary",id="terms"
+List of Terms
+-------------
+
+template="glossary",id="terms"
+List of Terms
+-------------
+.....................................................................
+
+2. When the title text matches a configuration file
+   <<X16,`specialsections`>> entry.
+3. If neither of the above the default `sect<level>` template is used
+   (where `<level>` is a number from 1 to 4).
+
+In addition to the normal section template names ('sect1', 'sect2',
+'sect3', 'sect4') AsciiDoc has the following templates for
+frontmatter, backmatter and other special sections: 'abstract',
+'preface', 'colophon', 'dedication', 'glossary', 'bibliography',
+'synopsis', 'appendix', 'index'.  These special section templates
+generate the corresponding Docbook elements; for HTML outputs they
+default to the 'sect1' section template.
+
+Section IDs
+^^^^^^^^^^^
+If no explicit section ID is specified an ID will be synthesised from
+the section title.  The primary purpose of this feature is to ensure
+persistence of table of contents links (permalinks): the missing
+section IDs are generated dynamically by the JavaScript TOC generator
+*after* the page is loaded. If you link to a dynamically generated TOC
+address the page will load but the browser will ignore the (as yet
+ungenerated) section ID.
+
+The IDs are generated by the following algorithm:
+
+- Replace all non-alphanumeric title characters with underscores.
+- Strip leading or trailing underscores.
+- Convert to lowercase.
+- Prepend the `idprefix` attribute (so there's no possibility of name
+  clashes with existing document IDs). Prepend an underscore if the
+  `idprefix` attribute is not defined.
+- A numbered suffix (`_2`, `_3` ...) is added if a same named
+  auto-generated section ID exists.
+- If the `ascii-ids` attribute is defined then non-ASCII characters
+  are replaced with ASCII equivalents. This attribute should be
+  *should be avoided* if possible as its sole purpose is to accommodate
+  deficient downstream applications that cannot process non-ASCII ID
+  attributes. If available, it will use the
+  https://pypi.org/project/trans/trans python module, otherwise it
+  will fallback to using NFKD algorithm, which cannot handle all
+  unicode characters. For example, 'Wstęp żółtej łąki' will be
+  translated to 'Wstep zoltej laki' under trans and 'Wstep zotej aki'
+  under NFKD.
+
+Example: the title 'Jim's House' would generate the ID `_jim_s_house`.
+
+Section ID synthesis can be disabled by undefining the `sectids`
+attribute.
+
+X16
+Special Section Titles
+^^^^^^^^^^^^^^^^^^^^^^
+AsciiDoc has a mechanism for mapping predefined section titles
+auto-magically to specific markup templates. For example a title
+'Appendix A: Code Reference' will automatically use the 'appendix'
+<<X93,section markup template>>. The mappings from title to template
+name are specified in `specialsections` sections in the Asciidoc
+language configuration files (`lang-*.conf`).  Section entries are
+formatted like:
+
+  <title>=<template>
+
+`<title>` is a Python regular expression and `<template>` is the name
+of a configuration file markup template section. If the `<title>`
+matches an AsciiDoc document section title then the backend output is
+marked up using the `<template>` markup template (instead of the
+default `sect<level>` section template). The `{title}` attribute value
+is set to the value of the matched regular expression group named
+'title', if there is no 'title' group `{title}` defaults to the whole
+of the AsciiDoc section title. If `<template>` is blank then any
+existing entry with the same `<title>` will be deleted.
+
+.Special section titles vs. explicit template names
+*********************************************************************
+AsciiDoc has two mechanisms for specifying non-default section markup
+templates: you can specify the template name explicitly (using the
+'template' attribute) or indirectly (using 'special section titles').
+Specifying a <<X93,section template>> attribute explicitly is
+preferred.  Auto-magical 'special section titles' have the following
+drawbacks:
+
+- They are non-obvious, you have to know the exact matching
+  title for each special section on a language by language basis.
+- Section titles are predefined and can only be customised with a
+  configuration change.
+- The implementation is complicated by multiple languages: every
+  special section title has to be defined for each language (in each
+  of the `lang-*.conf` files).
+
+Specifying special section template names explicitly does add more
+noise to the source document (the 'template' attribute declaration),
+but the intention is obvious and the syntax is consistent with other
+AsciiDoc elements c.f.  bibliographic, Q&A and glossary lists.
+
+Special section titles have been deprecated but are retained for
+backward compatibility.
+
+*********************************************************************
+
+Inline Elements
+~~~~~~~~~~~~~~~
+<<X34,Inline document elements>> are used to format text and to
+perform various types of text substitution. Inline elements and inline
+element syntax is defined in the asciidoc(1) configuration files.
+
+Here is a list of AsciiDoc inline elements in the (default) order in
+which they are processed:
+
+Special characters::
+        These character sequences escape special characters used by
+        the backend markup (typically `<`, `>`, and `&` characters).
+        See `specialcharacters` configuration file sections.
+
+Quotes::
+        Elements that markup words and phrases; usually for character
+        formatting. See `quotes` configuration file sections.
+
+Special Words::
+        Word or word phrase patterns singled out for markup without
+        the need for further annotation.  See `specialwords`
+        configuration file sections.
+
+Replacements::
+        Each replacement defines a word or word phrase pattern to
+        search for along with corresponding replacement text. See
+        `replacements` configuration file sections.
+
+Attribute references::
+        Document attribute names enclosed in braces are replaced by
+        the corresponding attribute value.
+
+Inline Macros::
+        Inline macros are replaced by the contents of parametrized
+        configuration file sections.
+
+
+Document Processing
+-------------------
+The AsciiDoc source document is read and processed as follows:
+
+1. The document 'Header' is parsed, header parameter values are
+   substituted into the configuration file `header` template section
+   which is then written to the output file.
+2. Each document 'Section' is processed and its constituent elements
+   translated to the output file.
+3. The configuration file `footer` template section is substituted
+   and written to the output file.
+
+When a block element is encountered asciidoc(1) determines the type of
+block by checking in the following order (first to last): (section)
+Titles, BlockMacros, Lists, DelimitedBlocks, Tables, AttributeEntrys,
+AttributeLists, BlockTitles, Paragraphs.
+
+The default paragraph definition `paradef-default` is last element
+to be checked.
+
+Knowing the parsing order will help you devise unambiguous macro, list
+and block syntax rules.
+
+Inline substitutions within block elements are performed in the
+following default order:
+
+1. Special characters
+2. Quotes
+3. Special words
+4. Replacements
+5. Attributes
+6. Inline Macros
+7. Replacements2
+
+The substitutions and substitution order performed on
+Title, Paragraph and DelimitedBlock elements is determined by
+configuration file parameters.
+
+
+Text Formatting
+---------------
+X51
+Quoted Text
+~~~~~~~~~~~
+Words and phrases can be formatted by enclosing inline text with
+quote characters:
+
+_Emphasized text_::
+        Word phrases \'enclosed in single quote characters' (acute
+        accents) or \_underline characters_ are emphasized.
+
+*Strong text*::
+        Word phrases \*enclosed in asterisk characters* are rendered
+        in a strong font (usually bold).
+
+X81+Monospaced text+::
+        Word phrases \+enclosed in plus characters+ are rendered in a
+        monospaced font. Word phrases \`enclosed in backtick
+        characters` (grave accents) are also rendered in a monospaced
+        font but in this case the enclosed text is rendered literally
+        and is not subject to further expansion (see <<X80,inline
+        literal passthrough>>).
+
+`Single quoted text'::
+        Phrases enclosed with a \`single grave accent to the left and
+        a single acute accent to the right' are rendered in single
+        quotation marks.
+
+``Double quoted text''::
+        Phrases enclosed with \\``two grave accents to the left and
+        two acute accents to the right'' are rendered in quotation
+        marks.
+
+#Unquoted text#::
+        Placing \#hashes around text# does nothing, it is a mechanism
+        to allow inline attributes to be applied to otherwise
+        unformatted text.
+
+New quote types can be defined by editing asciidoc(1) configuration
+files. See the <<X7,Configuration Files>> section for details.
+
+.Quoted text behavior
+- Quoting cannot be overlapped.
+- Different quoting types can be nested.
+- To suppress quoted text formatting place a backslash character
+  immediately in front of the leading quote character(s). In the case
+  of ambiguity between escaped and non-escaped text you will need to
+  escape both leading and trailing quotes, in the case of
+  multi-character quotes you may even need to escape individual
+  characters.
+
+X96
+Quoted text attributes
+^^^^^^^^^^^^^^^^^^^^^^
+Quoted text can be prefixed with an <<X21,attribute list>>.  The first
+positional attribute ('role' attribute) is translated by AsciiDoc to
+an HTML 'span' element 'class' attribute or a DocBook 'phrase' element
+'role' attribute.
+
+DocBook XSL Stylesheets translate DocBook 'phrase' elements with
+'role' attributes to corresponding HTML 'span' elements with the same
+'class' attributes; CSS can then be used
+http://www.sagehill.net/docbookxsl/UsingCSS.htmlto style the
+generated HTML.  Thus CSS styling can be applied to both DocBook and
+AsciiDoc generated HTML outputs.  You can also specify multiple class
+names separated by spaces.
+
+CSS rules for text color, text background color, text size and text
+decorators are included in the distributed AsciiDoc CSS files and are
+used in conjunction with AsciiDoc 'xhtml11', 'html5' and 'docbook'
+outputs. The CSS class names are:
+
+- '<color>' (text foreground color).
+- '<color>-background' (text background color).
+- 'big' and 'small' (text size).
+- 'underline', 'overline' and 'line-through' (strike through) text
+  decorators.
+
+Where '<color>' can be any of the
+https://en.wikipedia.org/wiki/Web_colors#HTML_color_namessixteen HTML
+color names.  Examples:
+
+  red#Obvious# and big red yellow-background*very obvious*.
+
+  underline#Underline text#, overline#overline text# and
+  blue line-through*bold blue and line-through*.
+
+is rendered as:
+
+red#Obvious# and big red yellow-background*very obvious*.
+
+underline#Underline text#, overline#overline text# and
+bold blue line-through*bold blue and line-through*.
+
+NOTE: Color and text decorator attributes are rendered for XHTML and
+HTML 5 outputs using CSS stylesheets.  The mechanism to implement
+color and text decorator attributes is provided for DocBook toolchains
+via the DocBook 'phrase' element 'role' attribute, but the actual
+rendering is toolchain specific and is not part of the AsciiDoc
+distribution.
+
+X52
+Constrained and Unconstrained Quotes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+There are actually two types of quotes:
+
+Constrained quotes
+++++++++++++++++++
+Quoted must be bounded by white space or commonly adjoining
+punctuation characters. These are the most commonly used type of
+quote.
+
+Unconstrained quotes
+++++++++++++++++++++
+Unconstrained quotes have no boundary constraints and can be placed
+anywhere within inline text. For consistency and to make them easier
+to remember unconstrained quotes are double-ups of the `_`, `*`, `+`
+and `#` constrained quotes:
+
+  __unconstrained emphasized text__
+  **unconstrained strong text**
+  ++unconstrained monospaced text++
+  ##unconstrained unquoted text##
+
+The following example emboldens the letter F:
+
+  **F**ile Open...
+
+Superscripts and Subscripts
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Put \^carets on either^ side of the text to be superscripted, put
+\~tildes on either side~ of text to be subscripted.  For example, the
+following line:
+
+  e^&#960;i^+1 = 0. H~2~O and x^10^. Some ^super text^
+  and ~some sub text~
+
+Is rendered like:
+
+e^&#960;i^+1 = 0. H~2~O and x^10^. Some ^super text^
+and ~some sub text~
+
+Superscripts and subscripts are implemented as <<X52,unconstrained
+quotes>> and they can be escaped with a leading backslash and prefixed
+with with an attribute list.
+
+Line Breaks
+~~~~~~~~~~~
+A plus character preceded by at least one space character at the end
+of a non-blank line forces a line break. It generates a line break
+(`br`) tag for HTML outputs and a custom XML `asciidoc-br` processing
+instruction for DocBook outputs. The `asciidoc-br` processing
+instruction is handled by <<X43,a2x(1)>>.
+
+Page Breaks
+~~~~~~~~~~~
+A line of three or more less-than (`<<<`) characters will generate a
+hard page break in DocBook and printed HTML outputs.  It uses the CSS
+`page-break-after` property for HTML outputs and a custom XML
+`asciidoc-pagebreak` processing instruction for DocBook outputs. The
+`asciidoc-pagebreak` processing instruction is handled by
+<<X43,a2x(1)>>. Hard page breaks are sometimes handy but as a general
+rule you should let your page processor generate page breaks for you.
+
+Rulers
+~~~~~~
+A line of three or more apostrophe characters will generate a ruler
+line.  It generates a ruler (`hr`) tag for HTML outputs and a custom
+XML `asciidoc-hr` processing instruction for DocBook outputs. The
+`asciidoc-hr` processing instruction is handled by <<X43,a2x(1)>>.
+
+Tabs
+~~~~
+By default tab characters input files will translated to 8 spaces. Tab
+expansion is set with the 'tabsize' entry in the configuration file
+`miscellaneous` section and can be overridden in included files by
+setting a 'tabsize' attribute in the `include` macro's attribute list.
+For example:
+
+  include::addendum.txttabsize=2
+
+The tab size can also be set using the attribute command-line option,
+for example `--attribute tabsize=4`
+
+Replacements
+~~~~~~~~~~~~
+The following replacements are defined in the default AsciiDoc
+configuration:
+
+  (C) copyright, (TM) trademark, (R) registered trademark,
+  -- em dash, ... ellipsis, -> right arrow, <- left arrow, => right
+  double arrow, <= left double arrow.
+
+Which are rendered as:
+
+(C) copyright, (TM) trademark, (R) registered trademark,
+-- em dash, ... ellipsis, -> right arrow, <- left arrow, => right
+double arrow, <= left double arrow.
+
+You can also include arbitrary entity references in the AsciiDoc
+source. Examples:
+
+  &#x278a; &#182;
+
+renders:
+
+&#x278a; &#182;
+
+To render a replacement literally escape it with a leading back-slash.
+
+The <<X7,Configuration Files>> section explains how to configure your
+own replacements.
+
+Special Words
+~~~~~~~~~~~~~
+Words defined in `specialwords` configuration file sections are
+automatically marked up without having to be explicitly notated.
+
+The <<X7,Configuration Files>> section explains how to add and replace
+special words.
+
+
+X17
+Titles
+------
+Document and section titles can be in either of two formats:
+
+Two line titles
+~~~~~~~~~~~~~~~
+A two line title consists of a title line, starting hard against the
+left margin, and an underline. Section underlines consist a repeated
+character pairs spanning the width of the preceding title (give or
+take up to two characters):
+
+The default title underlines for each of the document levels are:
+
+
+  Level 0 (top level):     ======================
+  Level 1:                 ----------------------
+  Level 2:                 ~~~~~~~~~~~~~~~~~~~~~~
+  Level 3:                 ^^^^^^^^^^^^^^^^^^^^^^
+  Level 4 (bottom level):  ++++++++++++++++++++++
+
+Examples:
+
+  Level One Section Title
+  -----------------------
+
+  Level 2 Subsection Title
+  ~~~~~~~~~~~~~~~~~~~~~~~~
+
+X46
+One line titles
+~~~~~~~~~~~~~~~
+One line titles consist of a single line delimited on either side by
+one or more equals characters (the number of equals characters
+corresponds to the section level minus one).  Here are some examples:
+
+  = Document Title (level 0) =
+  == Section title (level 1) ==
+  === Section title (level 2) ===
+  ==== Section title (level 3) ====
+  ===== Section title (level 4) =====
+
+NOTE
+=====================================================================
+- One or more spaces must fall between the title and the delimiters.
+- The trailing title delimiter is optional.
+- The one-line title syntax can be changed by editing the
+  configuration file `titles` section `sect0`...`sect4` entries.
+=====================================================================
+
+Floating titles
+~~~~~~~~~~~~~~~
+Setting the title's first positional attribute or 'style' attribute to
+'float' generates a free-floating title. A free-floating title is
+rendered just like a normal section title but is not formally
+associated with a text body and is not part of the regular section
+hierarchy so the normal ordering rules do not apply. Floating titles
+can also be used in contexts where section titles are illegal: for
+example sidebar and admonition blocks.  Example:
+
+  float
+  The second day
+  ~~~~~~~~~~~~~~
+
+Floating titles do not appear in a document's table of contents.
+
+
+X42
+Block Titles
+------------
+A 'BlockTitle' element is a single line beginning with a period
+followed by the title text. A BlockTitle is applied to the immediately
+following Paragraph, DelimitedBlock, List, Table or BlockMacro. For
+example:
+
+........................
+.Notes
+- Note 1.
+- Note 2.
+........................
+
+is rendered as:
+
+.Notes
+- Note 1.
+- Note 2.
+
+
+X41
+BlockId Element
+---------------
+A 'BlockId' is a single line block element containing a unique
+identifier enclosed in double square brackets. It is used to assign an
+identifier to the ensuing block element. For example:
+
+  chapter-titles
+  Chapter titles can be ...
+
+The preceding example identifies the ensuing paragraph so it can be
+referenced from other locations, for example with
+`<<chapter-titles,chapter titles>>`.
+
+'BlockId' elements can be applied to Title, Paragraph, List,
+DelimitedBlock, Table and BlockMacro elements.  The BlockId element
+sets the `{id}` attribute for substitution in the subsequent block's
+markup template. If a second positional argument is supplied it sets
+the `{reftext}` attribute which is used to set the DocBook `xreflabel`
+attribute.
+
+The 'BlockId' element has the same syntax and serves the same function
+to the <<X30,anchor inline macro>>.
+
+X79
+AttributeList Element
+---------------------
+An 'AttributeList' block element is an <<X21,attribute list>> on a
+line by itself:
+
+- 'AttributeList' attributes are only applied to the immediately
+  following block element -- the attributes are made available to the
+  block's markup template.
+- Multiple contiguous 'AttributeList' elements are additively combined
+  in the order they appear.
+- The first positional attribute in the list is often used to specify
+  the ensuing element's <<X23,style>>.
+
+Attribute value substitution
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+By default, only substitutions that take place inside attribute list
+values are attribute references, this is because not all attributes
+are destined to be marked up and rendered as text (for example the
+table 'cols' attribute). To perform normal inline text substitutions
+(special characters, quotes, macros, replacements) on an attribute
+value you need to enclose it in single quotes. In the following quote
+block the second attribute value in the AttributeList is quoted to
+ensure the 'http' macro is expanded to a hyperlink.
+
+---------------------------------------------------------------------
+quote,'https://en.wikipedia.org/wiki/Samuel_JohnsonSamuel Johnson'
+_____________________________________________________________________
+Sir, a woman's preaching is like a dog's walking on his hind legs. It
+is not done well; but you are surprised to find it done at all.
+_____________________________________________________________________
+---------------------------------------------------------------------
+
+Common attributes
+~~~~~~~~~~~~~~~~~
+Most block elements support the following attributes:
+
+cols="1e,1,5a",frame="topbot",options="header"
+|====================================================================
+|Name |Backends |Description
+
+|id |html4, html5, xhtml11, docbook |
+Unique identifier typically serve as link targets.
+Can also be set by the 'BlockId' element.
+
+|role |html4, html5, xhtml11, docbook |
+Role contains a string used to classify or subclassify an element and
+can be applied to AsciiDoc block elements.  The AsciiDoc 'role'
+attribute is translated to the 'role' attribute in DocBook outputs and
+is included in the 'class' attribute in HTML outputs, in this respect
+it behaves like the <<X96,quoted text role attribute>>.
+
+DocBook XSL Stylesheets translate DocBook 'role' attributes to HTML
+'class' attributes; CSS can then be used
+http://www.sagehill.net/docbookxsl/UsingCSS.htmlto style the
+generated HTML.
+
+|reftext |docbook |
+'reftext' is used to set the DocBook 'xreflabel' attribute.
+The 'reftext' attribute can an also be set by the 'BlockId' element.
+
+|floatstyle |docbook |
+'floatstyle' is used to specify the floatstyle attribute for the
+titled table, example, image and equation blocks. This is useful when
+used in conjuction with the dblatex toolchain. A typical example
+would be to specify the value as 'floatstyle="htbp"'.
+
+|====================================================================
+
+
+Paragraphs
+----------
+Paragraphs are blocks of text terminated by a blank line, the end of
+file, or the start of a delimited block or a list.  There are three
+paragraph syntaxes: normal, indented (literal) and admonition which
+are rendered, by default, with the corresponding paragraph style.
+
+Each syntax has a default style, but you can explicitly apply any
+paragraph style to any paragraph syntax. You can also apply
+<<X104,delimited block>> styles to single paragraphs.
+
+The built-in paragraph styles are: 'normal', 'literal', 'verse',
+'quote', 'listing', 'TIP', 'NOTE', 'IMPORTANT', 'WARNING', 'CAUTION',
+'abstract', 'partintro', 'comment', 'example', 'sidebar', 'source',
+'music', 'latex', 'graphviz'.
+
+normal paragraph syntax
+~~~~~~~~~~~~~~~~~~~~~~~
+Normal paragraph syntax consists of one or more non-blank lines of
+text. The first line must start hard against the left margin (no
+intervening white space). The default processing expectation is that
+of a normal paragraph of text.
+
+X85
+literal paragraph syntax
+~~~~~~~~~~~~~~~~~~~~~~~~
+Literal paragraphs are rendered verbatim in a monospaced font without
+any distinguishing background or border.  By default there is no text
+formatting or substitutions within Literal paragraphs apart from
+Special Characters and Callouts.
+
+The 'literal' style is applied implicitly to indented paragraphs i.e.
+where the first line of the paragraph is indented by one or more space
+or tab characters.  For example:
+
+---------------------------------------------------------------------
+  Consul *necessitatibus* per id,
+  consetetur, eu pro everti postulant
+  homero verear ea mea, qui.
+---------------------------------------------------------------------
+
+Renders:
+
+  Consul *necessitatibus* per id,
+  consetetur, eu pro everti postulant
+  homero verear ea mea, qui.
+
+NOTE: Because <<X64,lists>> can be indented it's possible for your
+indented paragraph to be misinterpreted as a list -- in situations
+like this apply the 'literal' style to a normal paragraph.
+
+Instead of using a paragraph indent you could apply the 'literal'
+style explicitly, for example:
+
+---------------------------------------------------------------------
+literal
+Consul *necessitatibus* per id,
+consetetur, eu pro everti postulant
+homero verear ea mea, qui.
+---------------------------------------------------------------------
+
+Renders:
+
+literal
+Consul *necessitatibus* per id,
+consetetur, eu pro everti postulant
+homero verear ea mea, qui.
+
+X94
+quote and verse paragraph styles
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The optional 'attribution' and 'citetitle' attributes (positional
+attributes 2 and 3) specify the author and source respectively.
+
+The 'verse' style retains the line breaks, for example:
+
+---------------------------------------------------------------------
+verse, William Blake, from Auguries of Innocence
+To see a world in a grain of sand,
+And a heaven in a wild flower,
+Hold infinity in the palm of your hand,
+And eternity in an hour.
+---------------------------------------------------------------------
+
+Which is rendered as:
+
+verse, William Blake, from Auguries of Innocence
+To see a world in a grain of sand,
+And a heaven in a wild flower,
+Hold infinity in the palm of your hand,
+And eternity in an hour.
+
+The 'quote' style flows the text at left and right margins, for
+example:
+
+---------------------------------------------------------------------
+quote, Bertrand Russell, The World of Mathematics (1956)
+A good notation has subtlety and suggestiveness which at times makes
+it almost seem like a live teacher.
+---------------------------------------------------------------------
+
+Which is rendered as:
+
+quote, Bertrand Russell, The World of Mathematics (1956)
+A good notation has subtlety and suggestiveness which at times makes
+it almost seem like a live teacher.
+
+X28
+Admonition Paragraphs
+~~~~~~~~~~~~~~~~~~~~~
+'TIP', 'NOTE', 'IMPORTANT', 'WARNING' and 'CAUTION' admonishment
+paragraph styles are generated by placing `NOTE:`, `TIP:`,
+`IMPORTANT:`, `WARNING:` or `CAUTION:` as the first word of the
+paragraph. For example:
+
+  NOTE: This is an example note.
+
+Alternatively, you can specify the paragraph admonition style
+explicitly using an <<X79,AttributeList element>>. For example:
+
+  NOTE
+  This is an example note.
+
+Renders:
+
+NOTE: This is an example note.
+
+TIP: If your admonition requires more than a single paragraph use an
+<<X22,admonition block>> instead.
+
+X47
+Admonition Icons and Captions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+NOTE: Admonition customization with `icons`, `iconsdir`, `icon` and
+`caption` attributes does not apply when generating DocBook output. If
+you are going the DocBook route then the <<X43,a2x(1)>> `--no-icons`
+and `--icons-dir` options can be used to set the appropriate XSL
+Stylesheets parameters.
+
+By default the asciidoc(1) HTML backends generate text captions
+instead of admonition icon image links. To generate links to icon
+images define the <<X45,`icons`>> attribute, for example using the `-a
+icons` command-line option.
+
+The <<X44,`iconsdir`>> attribute sets the location of linked icon
+images.
+
+You can override the default icon image using the `icon` attribute to
+specify the path of the linked image. For example:
+
+  icon="./images/icons/wink.png"
+  NOTE: What lovely war.
+
+Use the `caption` attribute to customize the admonition captions (not
+applicable to `docbook` backend). The following example suppresses the
+icon image and customizes the caption of a 'NOTE' admonition
+(undefining the `icons` attribute with `icons=None` is only necessary
+if <<X45,admonition icons>> have been enabled):
+
+  icons=None, caption="My Special Note"
+  NOTE: This is my special note.
+
+This subsection also applies to <<X22,Admonition Blocks>>.
+
+
+X104
+Delimited Blocks
+----------------
+Delimited blocks are blocks of text enveloped by leading and trailing
+delimiter lines (normally a series of four or more repeated
+characters). The behavior of Delimited Blocks is specified by entries
+in configuration file `blockdef-*` sections.
+
+Predefined Delimited Blocks
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+AsciiDoc ships with a number of predefined DelimitedBlocks (see the
+`asciidoc.conf` configuration file in the asciidoc(1) program
+directory):
+
+Predefined delimited block underlines:
+
+  CommentBlock:     //////////////////////////
+  PassthroughBlock: ++++++++++++++++++++++++++
+  ListingBlock:     --------------------------
+  LiteralBlock:     ..........................

+|=====================================================
+
+Listing Blocks
+~~~~~~~~~~~~~~
+'ListingBlocks' are rendered verbatim in a monospaced font, they
+retain line and whitespace formatting and are often distinguished by a
+background or border. There is no text formatting or substitutions
+within Listing blocks apart from Special Characters and Callouts.
+Listing blocks are often used for computer output and file listings.
+
+Here's an example:
+
+listing
+......................................
+--------------------------------------
+#include <stdio.h>
+
+int main() {
+   printf("Hello World!\n");
+   exit(0);
+}
+--------------------------------------
+......................................
+
+Which will be rendered like:
+
+--------------------------------------
+#include <stdio.h>
+
+int main() {
+    printf("Hello World!\n");
+    exit(0);
+}
+--------------------------------------
+
+By convention <<X59,filter blocks>> use the listing block syntax and
+are implemented as distinct listing block styles.
+
+X65
+Literal Blocks
+~~~~~~~~~~~~~~
+'LiteralBlocks' are rendered just like <<X85,literal paragraphs>>.
+Example:
+
+---------------------------------------------------------------------
+...................................
+Consul *necessitatibus* per id,
+consetetur, eu pro everti postulant
+homero verear ea mea, qui.
+...................................
+---------------------------------------------------------------------
+
+Renders:
+...................................
+Consul *necessitatibus* per id,
+consetetur, eu pro everti postulant
+homero verear ea mea, qui.
+...................................
+
+If the 'listing' style is applied to a LiteralBlock it will be
+rendered as a ListingBlock (this is handy if you have a listing
+containing a ListingBlock).
+
+Sidebar Blocks
+~~~~~~~~~~~~~~
+A sidebar is a short piece of text presented outside the narrative
+flow of the main text. The sidebar is normally presented inside a
+bordered box to set it apart from the main text.
+
+The sidebar body is treated like a normal section body.
+
+Here's an example:
+
+---------------------------------------------------------------------
+.An Example Sidebar
+************************************************
+Any AsciiDoc SectionBody element (apart from
+SidebarBlocks) can be placed inside a sidebar.
+************************************************
+---------------------------------------------------------------------
+
+Which will be rendered like:
+
+.An Example Sidebar
+************************************************
+Any AsciiDoc SectionBody element (apart from
+SidebarBlocks) can be placed inside a sidebar.
+************************************************
+
+X26
+Comment Blocks
+~~~~~~~~~~~~~~
+The contents of 'CommentBlocks' are not processed; they are useful for
+annotations and for excluding new or outdated content that you don't
+want displayed. CommentBlocks are never written to output files.
+Example:
+
+---------------------------------------------------------------------
+//////////////////////////////////////////
+CommentBlock contents are not processed by
+asciidoc(1).
+//////////////////////////////////////////
+---------------------------------------------------------------------
+
+See also <<X25,Comment Lines>>.
+
+NOTE: System macros are executed inside comment blocks.
+
+X76
+Passthrough Blocks
+~~~~~~~~~~~~~~~~~~
+By default the block contents is subject only to 'attributes' and
+'macros' substitutions (use an explicit 'subs' attribute to apply
+different substitutions).  PassthroughBlock content will often be
+backend specific. Here's an example:
+
+---------------------------------------------------------------------
+subs="quotes"
+++++++++++++++++++++++++++++++++++++++
+<table border="1"><tr>
+  <td>*Cell 1*</td>
+  <td>*Cell 2*</td>
+</tr></table>
+++++++++++++++++++++++++++++++++++++++
+---------------------------------------------------------------------
+
+The following styles can be applied to passthrough blocks:
+
+pass::
+  No substitutions are performed. This is equivalent to `subs="none"`.
+
+asciimath, latexmath::
+  By default no substitutions are performed, the contents are rendered
+  as <<X78,mathematical formulas>>.
+
+Quote Blocks
+~~~~~~~~~~~~
+'QuoteBlocks' are used for quoted passages of text. There are two
+styles: 'quote' and 'verse'. The style behavior is identical to
+<<X94,quote and verse paragraphs>> except that blocks can contain
+multiple paragraphs and, in the case of the 'quote' style, other
+section elements.  The first positional attribute sets the style, if
+no attributes are specified the 'quote' style is used.  The optional
+'attribution' and 'citetitle' attributes (positional attributes 2 and
+3) specify the quote's author and source. For example:
+
+---------------------------------------------------------------------
+quote, Sir Arthur Conan Doyle, The Adventures of Sherlock Holmes
+____________________________________________________________________
+As he spoke there was the sharp sound of horses' hoofs and
+grating wheels against the curb, followed by a sharp pull at the
+bell. Holmes whistled.
+
+"A pair, by the sound," said he. "Yes," he continued, glancing
+out of the window. "A nice little brougham and a pair of
+beauties. A hundred and fifty guineas apiece. There's money in
+this case, Watson, if there is nothing else."

+Example Blocks
+~~~~~~~~~~~~~~
+'ExampleBlocks' encapsulate the DocBook Example element and are used
+for, well, examples.  Example blocks can be titled by preceding them
+with a 'BlockTitle'.  DocBook toolchains will normally automatically
+number examples and generate a 'List of Examples' backmatter section.
+
+Example blocks are delimited by lines of equals characters and can
+contain any block elements apart from Titles, BlockTitles and
+Sidebars) inside an example block. For example:
+
+---------------------------------------------------------------------
+.An example
+=====================================================================
+Qui in magna commodo, est labitur dolorum an. Est ne magna primis
+adolescens.

+(HTML backends). For example:

+Admonition Blocks
+~~~~~~~~~~~~~~~~~
+The 'ExampleBlock' definition includes a set of admonition
+<<X23,styles>> ('NOTE', 'TIP', 'IMPORTANT', 'WARNING', 'CAUTION') for
+generating admonition blocks (admonitions containing more than a
+<<X28,single paragraph>>).  Just precede the 'ExampleBlock' with an
+attribute list specifying the admonition style name. For example:
+
+---------------------------------------------------------------------
+NOTE
+.A NOTE admonition block
+=====================================================================
+Qui in magna commodo, est labitur dolorum an. Est ne magna primis
+adolescens.
+
+. Fusce euismod commodo velit.
+. Vivamus fringilla mi eu lacus.
+  .. Fusce euismod commodo velit.

+Open Blocks
+~~~~~~~~~~~
+Open blocks are special:
+
+- The open block delimiter is line containing two hyphen characters
+  (instead of four or more repeated characters).
+
+- They can be used to group block elements for <<X15,List item
+  continuation>>.
+
+- Open blocks can be styled to behave like any other type of delimited
+  block.  The  following built-in styles can be applied to open
+  blocks: 'literal', 'verse', 'quote', 'listing', 'TIP', 'NOTE',
+  'IMPORTANT', 'WARNING', 'CAUTION', 'abstract', 'partintro',
+  'comment', 'example', 'sidebar', 'source', 'music', 'latex',
+  'graphviz'. For example, the following open block and listing block
+  are functionally identical:
+
+  listing
+  --
+  Lorum ipsum ...
+  --
+
+  ---------------
+  Lorum ipsum ...
+  ---------------
+
+- An unstyled open block groups section elements but otherwise does
+  nothing.
+
+Open blocks are used to generate document abstracts and book part
+introductions:
+
+- Apply the 'abstract' style to generate an abstract, for example:
+
+  abstract
+  --
+  In this paper we will ...
+  --
+
+. Apply the 'partintro' style to generate a book part introduction for
+  a multi-part book, for example:
+
+  partintro
+  .Optional part introduction title
+  --
+  Optional part introduction goes here.

+Lists
+-----
+.List types
+- Bulleted lists. Also known as itemized or unordered lists.
+- Numbered lists. Also called ordered lists.
+- Labeled lists. Sometimes called variable or definition lists.
+- Callout lists (a list of callout annotations).
+
+.List behavior
+- List item indentation is optional and does not determine nesting,
+  indentation does however make the source more readable.
+- Another list or a literal paragraph immediately following a list
+  item will be implicitly included in the list item; use <<X15, list
+  item continuation>> to explicitly append other block elements to a
+  list item.
+- A comment block or a comment line block macro element will terminate
+  a list -- use inline comment lines to put comments inside lists.
+- The `listindex` <<X60,intrinsic attribute>> is the current list item
+  index (1..). If this attribute is used outside a list then it's value
+  is the number of items in the most recently closed list. Useful for
+  displaying the number of items in a list.
+
+Bulleted Lists
+~~~~~~~~~~~~~~
+Bulleted list items start with a single dash or one to five asterisks
+followed by some white space then some text. Bulleted list syntaxes
+are:
+
+...................
+- List item.
+* List item.
+** List item.
+*** List item.
+**** List item.
+***** List item.
+...................
+
+Numbered Lists
+~~~~~~~~~~~~~~
+List item numbers are explicit or implicit.
+
+.Explicit numbering
+List items begin with a number followed by some white space then the
+item text. The numbers can be decimal (arabic), roman (upper or lower
+case) or alpha (upper or lower case). Decimal and alpha numbers are
+terminated with a period, roman numbers are terminated with a closing
+parenthesis. The different terminators are necessary to ensure 'i',
+'v' and 'x' roman numbers are are distinguishable from 'x', 'v' and
+'x' alpha numbers. Examples:
+
+.....................................................................
+1.   Arabic (decimal) numbered list item.
+a.   Lower case alpha (letter) numbered list item.
+F.   Upper case alpha (letter) numbered list item.
+iii) Lower case roman numbered list item.
+IX)  Upper case roman numbered list item.
+.....................................................................
+
+.Implicit numbering
+List items begin one to five period characters, followed by some white
+space then the item text. Examples:
+
+.....................................................................
+. Arabic (decimal) numbered list item.
+.. Lower case alpha (letter) numbered list item.
+... Lower case roman numbered list item.
+.... Upper case alpha (letter) numbered list item.
+..... Upper case roman numbered list item.
+.....................................................................
+
+You can use the 'style' attribute (also the first positional
+attribute) to specify an alternative numbering style.  The numbered
+list style can be one of the following values: 'arabic', 'loweralpha',
+'upperalpha', 'lowerroman', 'upperroman'.
+
+Here are some examples of bulleted and numbered lists:
+
+---------------------------------------------------------------------

+    a. Fusce euismod commodo velit.

+    .. Fusce euismod commodo velit.
+    .. Vivamus fringilla mi eu lacus.
+  . Donec eget arcu bibendum nunc consequat lobortis.
+
+A predefined 'compact' option is available to bulleted and numbered
+lists -- this translates to the DocBook 'spacing="compact"' lists
+attribute which may or may not be processed by the DocBook toolchain.
+Example:
+
+  options="compact"
+  - Compact list item.
+  - Another compact list item.
+
+TIP: To apply the 'compact' option globally define a document-wide
+'compact-option' attribute, e.g. using the `-a compact-option`
+command-line option.
+
+You can set the list start number using the 'start' attribute (works
+for HTML outputs and DocBook outputs processed by DocBook XSL
+Stylesheets). Example:
+
+  start=7
+  . List item 7.
+  . List item 8.
+
+Labeled Lists
+~~~~~~~~~~~~~
+Labeled list items consist of one or more text labels followed by the
+text of the list item.
+
+An item label begins a line with an alphanumeric character hard
+against the left margin and ends with two, three or four colons or two
+semi-colons. A list item can have multiple labels, one per line.
+
+The list item text consists of one or more lines of text starting
+after the last label (either on the same line or a new line) and can
+be followed by nested List or ListParagraph elements. Item text can be
+optionally indented.
+
+Here are some examples:
+
+---------------------------------------------------------------------
+In::
+Lorem::
+  Fusce euismod commodo velit.
+
+  Fusce euismod commodo velit.
+
+Ipsum:: Vivamus fringilla mi eu lacus.
+  * Vivamus fringilla mi eu lacus.
+  * Donec eget arcu bibendum nunc consequat lobortis.
+Dolor::
+  Donec eget arcu bibendum nunc consequat lobortis.
+  Suspendisse;;
+    A massa id sem aliquam auctor.
+  Morbi;;
+    Pretium nulla vel lorem.
+  In;;
+    Dictum mauris in urna.
+    Vivamus::: Fringilla mi eu lacus.
+    Donec:::   Eget arcu bibendum nunc consequat lobortis.
+---------------------------------------------------------------------
+
+Which render as:
+
+In::
+Lorem::
+  Fusce euismod commodo velit.
+
+  Fusce euismod commodo velit.
+
+Ipsum:: Vivamus fringilla mi eu lacus.
+  * Vivamus fringilla mi eu lacus.
+  * Donec eget arcu bibendum nunc consequat lobortis.
+Dolor::
+  Donec eget arcu bibendum nunc consequat lobortis.
+  Suspendisse;;
+    A massa id sem aliquam auctor.
+  Morbi;;
+    Pretium nulla vel lorem.
+  In;;
+    Dictum mauris in urna.
+    Vivamus::: Fringilla mi eu lacus.
+    Donec:::   Eget arcu bibendum nunc consequat lobortis.
+
+Horizontal labeled list style
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The 'horizontal' labeled list style (also the first positional
+attribute) places the list text side-by-side with the label instead of
+under the label. Here is an example:
+
+---------------------------------------------------------------------
+horizontal
+*Lorem*:: Fusce euismod commodo velit.  Qui in magna commodo, est
+labitur dolorum an. Est ne magna primis adolescens.
+
+  Fusce euismod commodo velit.
+
+*Ipsum*:: Vivamus fringilla mi eu lacus.
+- Vivamus fringilla mi eu lacus.
+- Donec eget arcu bibendum nunc consequat lobortis.
+
+*Dolor*::
+  - Vivamus fringilla mi eu lacus.
+  - Donec eget arcu bibendum nunc consequat lobortis.
+
+---------------------------------------------------------------------
+
+Which render as:
+
+horizontal
+*Lorem*:: Fusce euismod commodo velit.  Qui in magna commodo, est
+labitur dolorum an. Est ne magna primis adolescens.
+
+  Fusce euismod commodo velit.
+
+*Ipsum*:: Vivamus fringilla mi eu lacus.
+- Vivamus fringilla mi eu lacus.
+- Donec eget arcu bibendum nunc consequat lobortis.
+
+*Dolor*::
+  - Vivamus fringilla mi eu lacus.
+  - Donec eget arcu bibendum nunc consequat lobortis.
+
+NOTE
+=====================================================================
+- Current PDF toolchains do not make a good job of determining
+  the relative column widths for horizontal labeled lists.
+- Nested horizontal labeled lists will generate DocBook validation
+  errors because the 'DocBook XML V4.2' DTD does not permit nested
+  informal tables (although <<X13,DocBook XSL Stylesheets>> and
+  <<X31,dblatex>> process them correctly).
+- The label width can be set as a percentage of the total width by
+  setting the 'width' attribute e.g. `width="10%"`
+=====================================================================
+
+Question and Answer Lists
+~~~~~~~~~~~~~~~~~~~~~~~~~
+AsciiDoc comes pre-configured with a 'qanda' style labeled list for generating
+DocBook question and answer (Q&A) lists. Example:
+
+---------------------------------------------------------------------
+qanda
+Question one::
+        Answer one.
+Question two::
+        Answer two.
+---------------------------------------------------------------------
+
+Renders:
+
+qanda
+Question one::
+        Answer one.
+Question two::
+        Answer two.
+
+Glossary Lists
+~~~~~~~~~~~~~~
+AsciiDoc comes pre-configured with a 'glossary' style labeled list for
+generating DocBook glossary lists. Example:
+
+---------------------------------------------------------------------
+glossary
+A glossary term::
+    The corresponding definition.
+A second glossary term::
+    The corresponding definition.
+---------------------------------------------------------------------
+
+For working examples see the `article.txt` and `book.txt` documents in
+the AsciiDoc `./doc` distribution directory.
+
+NOTE: To generate valid DocBook output glossary lists must be located
+in a section that uses the 'glossary' <<X93,section markup template>>.
+
+Bibliography Lists
+~~~~~~~~~~~~~~~~~~
+AsciiDoc comes with a predefined 'bibliography' bulleted list style
+generating DocBook bibliography entries. Example:
+
+---------------------------------------------------------------------
+bibliography
+.Optional list title
+- taoup Eric Steven Raymond. 'The Art of UNIX
+  Programming'. Addison-Wesley. ISBN 0-13-142901-9.
+- walsh-muellner Norman Walsh & Leonard Muellner.
+  'DocBook - The Definitive Guide'. O'Reilly & Associates. 1999.
+  ISBN 1-56592-580-7.
+---------------------------------------------------------------------
+
+The `<reference>` syntax is a bibliography entry anchor, it
+generates an anchor named `<reference>` and additionally displays
+`<reference>` at the anchor position. For example `taoup`
+generates an anchor named `taoup` that displays `taoup` at the
+anchor position. Cite the reference from elsewhere your document using
+`<<taoup>>`, this displays a hyperlink (`taoup`) to the
+corresponding bibliography entry anchor.
+
+For working examples see the `article.txt` and `book.txt` documents in
+the AsciiDoc `./doc` distribution directory.
+
+NOTE: To generate valid DocBook output bibliography lists must be
+located in a <<X93,bibliography section>>.
+
+X15
+List Item Continuation
+~~~~~~~~~~~~~~~~~~~~~~
+Another list or a literal paragraph immediately following a list item
+is implicitly appended to the list item; to append other block
+elements to a list item you need to explicitly join them to the list
+item with a 'list continuation' (a separator line containing a single
+plus character). Multiple block elements can be appended to a list
+item using list continuations (provided they are legal list item
+children in the backend markup).
+
+Here are some examples of list item continuations: list item one
+contains multiple continuations; list item two is continued with an
+<<X29,OpenBlock>> containing multiple elements:
+
+---------------------------------------------------------------------
+1. List item one.
++
+List item one continued with a second paragraph followed by an
+Indented block.
++
+.................
+$ ls *.sh
+$ mv *.sh ~/tmp
+.................
++
+List item continued with a third paragraph.
+
+2. List item two continued with an open block.
++
+--
+This paragraph is part of the preceding list item.
+
+a. This list is nested and does not require explicit item continuation.
++
+This paragraph is part of the preceding list item.
+
+b. List item b.
+
+This paragraph belongs to item two of the outer list.

+Footnotes
+---------
+The shipped AsciiDoc configuration includes three footnote inline
+macros:
+
+`footnote:<text>`::
+  Generates a footnote with text `<text>`.
+
+`footnoteref:<id>,<text>`::
+  Generates a footnote with a reference ID `<id>` and text `<text>`.
+
+`footnoteref:<id>`::
+  Generates a reference to the footnote with ID `<id>`.
+
+The footnote text can span multiple lines.
+
+The 'xhtml11' and 'html5' backends render footnotes dynamically using
+JavaScript; 'html4' outputs do not use JavaScript and leave the
+footnotes inline; 'docbook' footnotes are processed by the downstream
+DocBook toolchain.
+
+Example footnotes:
+
+  A footnote footnote:An example footnote.;
+  a second footnote with a reference ID footnoteref:note2,Second footnote.;
+  finally a reference to the second footnote footnoteref:note2.
+
+Renders:
+
+A footnote footnote:An example footnote.;
+a second footnote with a reference ID footnoteref:note2,Second footnote.;
+finally a reference to the second footnote footnoteref:note2.
+
+
+Indexes
+-------
+The shipped AsciiDoc configuration includes the inline macros for
+generating DocBook index entries.
+
+`indexterm:<primary>,<secondary>,<tertiary>`::
+`(((<primary>,<secondary>,<tertiary>)))`::
+    This inline macro generates an index term (the `<secondary>` and
+    `<tertiary>` positional attributes are optional). Example:
+    `indexterm:Tigers,Big cats` (or, using the alternative syntax
+    `(((Tigers,Big cats)))`.  Index terms that have secondary and
+    tertiary entries also generate separate index terms for the
+    secondary and tertiary entries. The index terms appear in the
+    index, not the primary text flow.
+
+`indexterm2:<primary>`::
+`((<primary>))`::
+    This inline macro generates an index term that appears in both the
+    index and the primary text flow.  The `<primary>` should not be
+    padded to the left or right with white space characters.
+
+For working examples see the `article.txt` and `book.txt` documents in
+the AsciiDoc `./doc` distribution directory.
+
+NOTE: Index entries only really make sense if you are generating
+DocBook markup -- DocBook conversion programs automatically generate
+an index at the point an 'Index' section appears in source document.
+

+Callouts
+--------
+Callouts are a mechanism for annotating verbatim text (for example:
+source code, computer output and user input). Callout markers are
+placed inside the annotated text while the actual annotations are
+presented in a callout list after the annotated text. Here's an
+example:

+.Explanation
+- The callout marks are whole numbers enclosed in angle brackets --
+  they refer to the correspondingly numbered item in the following
+  callout list.
+- By default callout marks are confined to 'LiteralParagraphs',
+  'LiteralBlocks' and 'ListingBlocks' (although this is a
+  configuration file option and can be changed).
+- Callout list item numbering is fairly relaxed -- list items can
+  start with `<n>`, `n>` or `>` where `n` is the optional list item
+  number (in the latter case list items starting with a single `>`
+  character are implicitly numbered starting at one).
+- Callout lists should not be nested.
+- Callout lists cannot be used within tables.
+- Callout lists start list items hard against the left margin.
+- If you want to present a number inside angle brackets you'll need to
+  escape it with a backslash to prevent it being interpreted as a
+  callout mark.
+
+NOTE: Define the AsciiDoc 'icons' attribute (for example using the `-a
+icons` command-line option) to display callout icons.

+Callout marks are generated by the 'callout' inline macro while
+callout lists are generated using the 'callout' list definition. The
+'callout' macro and 'callout' list are special in that they work
+together. The 'callout' inline macro is not enabled by the normal
+'macros' substitutions option, instead it has its own 'callouts'
+substitution option.
+
+The following attributes are available during inline callout macro
+substitution:
+
+`{index}`::
+    The callout list item index inside the angle brackets.
+`{coid}`::
+    An identifier formatted like `CO<listnumber>-<index>` that
+    uniquely identifies the callout mark. For example `CO2-4`
+    identifies the fourth callout mark in the second set of callout
+    marks.
+
+The `{coids}` attribute can be used during callout list item
+substitution -- it is a space delimited list of callout IDs that refer
+to the explanatory list item.
+
+Including callouts in included code
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can annotate working code examples with callouts -- just remember
+to put the callouts inside source code comments. This example displays
+the `test.py` source file (containing a single callout) using the
+'source' (code highlighter) filter:
+
+.AsciiDoc source
+---------------------------------------------------------------------
+ source,python
+ -------------------------------------------
+ \include::test.py
+ -------------------------------------------
+
+ \<1> Print statement.
+---------------------------------------------------------------------
+
+.Included `test.py` source
+---------------------------------------------------------------------
+print 'Hello World!'   # \<1>
+---------------------------------------------------------------------
+
+
+Macros
+------
+Macros are a mechanism for substituting parametrized text into output
+documents.
+
+Macros have a 'name', a single 'target' argument and an 'attribute
+list'.  The usual syntax is `<name>:<target><attrlist>` (for
+inline macros) and `<name>::<target><attrlist>` (for block
+macros).  Here are some examples:
+
+  https://docbook.org/DocBook.org
+  include::chapt1.txttabsize=2
+  mailto:srackham@gmail.com
+
+.Macro behavior
+- `<name>` is the macro name. It can only contain letters, digits or
+  dash characters and cannot start with a dash.
+- The optional `<target>` cannot contain white space characters.
+- `<attrlist>` is a <<X21,list of attributes>> enclosed in square
+  brackets.
+- `` characters inside attribute lists must be escaped with a
+  backslash.
+- Expansion of macro references can normally be escaped by prefixing a
+  backslash character (see the AsciiDoc 'FAQ' for examples of
+  exceptions to this rule).
+- Attribute references in block macros are expanded.
+- The substitutions performed prior to Inline macro macro expansion
+  are determined by the inline context.
+- Macros are processed in the order they appear in the configuration
+  file(s).
+- Calls to inline macros can be nested inside different inline macros
+  (an inline macro call cannot contain a nested call to itself).
+- In addition to `<name>`, `<target>` and `<attrlist>` the
+  `<passtext>` and `<subslist>` named groups are available to
+  <<X77,passthrough macros>>. A macro is a passthrough macro if the
+  definition includes a `<passtext>` named group.
+
+Inline Macros
+~~~~~~~~~~~~~
+Inline Macros occur in an inline element context. Predefined Inline
+macros include 'URLs', 'image' and 'link' macros.
+
+URLs
+^^^^
+'http', 'https', 'ftp', 'file', 'mailto' and 'callto' URLs are
+rendered using predefined inline macros.
+
+- If you don't need a custom link caption you can enter the 'http',
+  'https', 'ftp', 'file' URLs and email addresses without any special
+  macro syntax.
+- If the `<attrlist>` is empty the URL is displayed.
+
+Here are some examples:
+
+  https://docbook.org/DocBook.org
+  https://docbook.org/
+  mailto:joe.bloggs@foobar.comemail Joe Bloggs
+  joe.bloggs@foobar.com
+
+Which are rendered:
+
+https://docbook.org/DocBook.org
+
+https://docbook.org/
+
+mailto:joe.bloggs@foobar.comemail Joe Bloggs
+
+joe.bloggs@foobar.com
+
+If the `<target>` necessitates space characters use `%20`, for example
+`large%20image.png`.
+
+Internal Cross References
+^^^^^^^^^^^^^^^^^^^^^^^^^
+Two AsciiDoc inline macros are provided for creating hypertext links
+within an AsciiDoc document. You can use either the standard macro
+syntax or the (preferred) alternative.
+
+X30
+anchor
+++++++
+Used to specify hypertext link targets:
+
+  <id>,<xreflabel>
+  anchor:<id><xreflabel>
+
+The `<id>` is a unique string that conforms to the output markup's
+anchor syntax. The optional `<xreflabel>` is the text to be displayed
+by captionless 'xref' macros that refer to this anchor. The optional
+`<xreflabel>` is only really useful when generating DocBook output.
+Example anchor:
+
+  X1
+
+You may have noticed that the syntax of this inline element is the
+same as that of the <<X41,BlockId block element>>, this is no
+coincidence since they are functionally equivalent.
+
+xref
+++++
+Creates a hypertext link to a document anchor.
+
+  <<<id>,<caption>>>
+  xref:<id><caption>
+
+The `<id>` refers to an anchor ID. The optional `<caption>` is the
+link's displayed text. Example:
+
+  <<X21,attribute lists>>
+
+If `<caption>` is not specified then the displayed text is
+auto-generated:
+
+- The AsciiDoc 'xhtml11' and 'html5' backends display the `<id>`
+  enclosed in square brackets.
+- If DocBook is produced the DocBook toolchain is responsible for the
+  displayed text which will normally be the referenced figure, table
+  or section title number followed by the element's title text.
+
+Here is an example:
+
+---------------------------------------------------------------------
+tiger_image
+.Tyger tyger
+image::tiger.png
+
+This can be seen in <<tiger_image>>.
+---------------------------------------------------------------------
+
+Linking to Local Documents
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+Hypertext links to files on the local file system are specified using
+the 'link' inline macro.
+
+  link:<target><caption>
+
+The 'link' macro generates relative URLs. The link macro `<target>` is
+the target file name (relative to the file system location of the
+referring document). The optional `<caption>` is the link's displayed
+text. If `<caption>` is not specified then `<target>` is displayed.
+Example:
+
+  link:downloads/foo.zipdownload foo.zip
+
+You can use the `<filename>#<id>` syntax to refer to an anchor within
+a target document but this usually only makes sense when targeting
+HTML documents.
+
+X9
+Images
+^^^^^^
+Inline images are inserted into the output document using the 'image'
+macro. The inline syntax is:
+
+  image:<target><attributes>
+
+The contents of the image file `<target>` is displayed. To display the
+image its file format must be supported by the target backend
+application. HTML and DocBook applications normally support PNG or JPG
+files.
+
+`<target>` file name paths are relative to the location of the
+referring document.
+
+X55
+.Image macro attributes
+- The optional 'alt' attribute is also the first positional attribute,
+  it specifies alternative text which is displayed if the output
+  application is unable to display the image file (see also
+  https://htmlhelp.com/feature/art3.htmUse of ALT texts in IMGs). For
+  example:
+
+  image:images/logo.pngCompany Logo
+
+- The optional 'title' attribute provides a title for the image. The
+  <<X49,block image macro>> renders the title alongside the image.
+  The inline image macro displays the title as a popup ``tooltip'' in
+  visual browsers (AsciiDoc HTML outputs only).
+
+- The optional `width` and `height` attributes scale the image size
+  and can be used in any combination. The units are pixels.  The
+  following example scales the previous example to a height of 32
+  pixels:
+
+  image:images/logo.png"Company Logo",height=32
+
+- The optional `link` attribute is used to link the image to an
+  external document. The following example links a screenshot
+  thumbnail to a full size version:
+
+  image:screen-thumbnail.pngheight=32,link="screen.png"
+
+- The optional `scaledwidth` attribute is only used in DocBook block
+  images (specifically for PDF documents). The following example
+  scales the images to 75% of the available print width:
+
+  image::images/logo.pngscaledwidth="75%",alt="Company Logo"
+
+- The image `scale` attribute sets the DocBook `imagedata` element
+  `scale` attribute.
+
+- The optional `align` attribute aligns block macro images
+  horizontally.  Allowed values are `center`, `left` and `right`. For
+  example:
+
+  image::images/tiger.png"Tiger image",align="left"
+
+- The optional `float` attribute floats the image `left` or `right` on
+  the page (works with HTML outputs only, has no effect on DocBook
+  outputs). `float` and `align` attributes are mutually exclusive.
+  Use the `unfloat::` block macro to stop floating.
+
+Comment Lines
+^^^^^^^^^^^^^
+See <<X25,comment block macro>>.
+
+Block Macros
+~~~~~~~~~~~~
+A Block macro reference must be contained in a single line separated
+either side by a blank line or a block delimiter.
+
+Block macros behave just like Inline macros, with the following
+differences:
+
+- They occur in a block context.
+- The default syntax is `<name>::<target><attrlist>` (two
+  colons, not one).
+- Markup template section names end in `-blockmacro` instead of
+  `-inlinemacro`.
+
+Block Identifier
+^^^^^^^^^^^^^^^^
+The Block Identifier macro sets the `id` attribute and has the same
+syntax as the <<X30,anchor inline macro>> since it performs
+essentially the same function -- block templates use the `id`
+attribute as a block element ID. For example:
+
+  X30
+
+This is equivalent to the `id="X30"` <<X79,AttributeList element>>).
+
+X49
+Images
+^^^^^^
+The 'image' block macro is used to display images in a block context.
+The syntax is:
+
+  image::<target><attributes>
+
+The block `image` macro has the same <<X55,macro attributes>> as it's
+<<X9,inline image macro>> counterpart.
+
+WARNING: Unlike the inline `image` macro, the entire block `image` macro
+must be on a single line.
+
+Block images can be titled by preceding the 'image' macro with a
+'BlockTitle'.  DocBook toolchains normally number titled block images
+and optionally list them in an automatically generated 'List of
+Figures' backmatter section.
+
+This example:
+
+  .Main circuit board
+  image::images/layout.pngJ14P main circuit board
+
+is equivalent to:
+
+  image::images/layout.png"J14P main circuit board", title="Main circuit board"
+
+A title prefix that can be inserted with the `caption` attribute
+(HTML backends). For example:
+
+  .Main circuit board
+  caption="Figure 2: "
+  image::images/layout.pngJ14P main circuit board
+
+X66
+.Embedding images in XHTML documents
+*********************************************************************
+If you define the `data-uri` attribute then images will be embedded in
+XHTML outputs using the
+https://en.wikipedia.org/wiki/Data_URI_schemedata URI scheme.  You
+can use the 'data-uri' attribute with the 'xhtml11' and 'html5'
+backends to produce single-file XHTML documents with embedded images
+and CSS, for example:
+
+  $ asciidoc -a data-uri mydocument.txt
+
+NOTE
+======
+- All current popular browsers support data URIs, although versions
+  of Internet Explorer prior to version 8 do not.
+- Some browsers limit the size of data URIs.
+======
+*********************************************************************
+
+X25
+Comment Lines
+^^^^^^^^^^^^^
+Single lines starting with two forward slashes hard up against the
+left margin are treated as comments. Comment lines do not appear in
+the output unless the 'showcomments' attribute is defined.  Comment
+lines have been implemented as both block and inline macros so a
+comment line can appear as a stand-alone block or within block elements
+that support inline macro expansion. Example comment line:
+
+  // This is a comment.
+
+If the 'showcomments' attribute is defined comment lines are written
+to the output:
+
+- In DocBook the comment lines are enclosed by the 'remark' element
+  (which may or may not be rendered by your toolchain).
+- The 'showcomments' attribute does not expose <<X26,Comment Blocks>>.
+  Comment Blocks are never passed to the output.
+
+System Macros
+~~~~~~~~~~~~~
+System macros are block macros that perform a predefined task and are
+hardwired into the asciidoc(1) program.
+
+- You can escape system macros with a leading backslash character
+  (as you can with other macros).
+- The syntax and tasks performed by system macros is built into
+  asciidoc(1) so they don't appear in configuration files.  You can
+  however customize the syntax by adding entries to a configuration
+  file `macros` section.
+
+X63
+Include Macros
+^^^^^^^^^^^^^^
+The `include` and `include1`  system macros to include the contents of
+a named file into the source document.
+
+The `include` macro includes a file as if it were part of the parent
+document -- tabs are expanded and system macros processed. The
+contents of `include1` files are not subject to tab expansion or
+system macro processing nor are attribute or lower priority
+substitutions performed. The `include1` macro's intended use is to
+include verbatim embedded CSS or scripts into configuration file
+headers.  Example:
+
+------------------------------------
+\include::chapter1.txttabsize=4
+------------------------------------
+
+.Include macro behavior
+- If the included file name is specified with a relative path then the
+  path is relative to the location of the referring document.
+- Include macros can appear inside configuration files.
+- Files included from within 'DelimitedBlocks' are read to completion
+  to avoid false end-of-block underline termination.
+- Attribute references are expanded inside the include 'target'; if an
+  attribute is undefined then the included file is silently skipped.
+- The 'tabsize' macro attribute sets the number of space characters to
+  be used for tab expansion in the included file (not applicable to
+  `include1` macro).
+- The 'depth' macro attribute sets the maximum permitted number of
+  subsequent nested includes (not applicable to `include1` macro which
+  does not process nested includes). Setting 'depth' to '1' disables
+  nesting inside the included file. By default, nesting is limited to
+  a depth of ten.
+- The `lines` macro attribute can be used to include specific lines of
+  the file. You can specify a range of pages by using `..` between
+  the two numbers, for example `1..10` would include the first 10
+  lines. You can include multiple ranges or invdividual pages by using
+  a comma or semi-colon, for example `1..10,45,50..60`.
+- If the 'warnings' attribute is set to 'False' (or any other
+  Python literal that evaluates to boolean false) then no warning
+  message is printed if the included file does not exist. By default
+  'warnings' are enabled.
+- Internally the `include1` macro is translated to the `include1`
+  system attribute which means it must be evaluated in a region where
+  attribute substitution is enabled. To inhibit nested substitution in
+  included files it is preferable to use the `include` macro and set
+  the attribute `depth=1`.
+
+Conditional Inclusion Macros
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Lines of text in the source document can be selectively included or
+excluded from processing based on the existence (or not) of a document
+attribute.
+
+Document text between the `ifdef` and `endif` macros is included if a
+document attribute is defined:
+
+  ifdef::<attribute>
+  :
+  endif::<attribute>
+
+Document text between the `ifndef` and `endif` macros is not included
+if a document attribute is defined:
+
+  ifndef::<attribute>
+  :
+  endif::<attribute>
+
+`<attribute>` is an attribute name which is optional in the trailing
+`endif` macro.
+
+If you only want to process a single line of text then the text can be
+put inside the square brackets and the `endif` macro omitted, for
+example:
+
+  ifdef::revnumberVersion number 42
+
+Is equivalent to:
+
+  ifdef::revnumber
+  Version number 42
+  endif::revnumber
+
+'ifdef' and 'ifndef' macros also accept multiple attribute names:
+
+- Multiple ',' separated attribute names evaluate to defined if one
+  or more of the attributes is defined, otherwise it's value is
+  undefined.
+- Multiple '+' separated attribute names evaluate to defined if all
+  of the attributes is defined, otherwise it's value is undefined.
+
+Document text between the `ifeval` and `endif` macros is included if
+the Python expression inside the square brackets is true. Example:
+
+  ifeval::{rs458}==2
+  :
+  endif::
+
+- Document attribute references are expanded before the expression is
+  evaluated.
+- If an attribute reference is undefined then the expression is
+  considered false.
+
+Take a look at the `*.conf` configuration files in the AsciiDoc
+distribution for examples of conditional inclusion macro usage.
+
+Executable system macros
+^^^^^^^^^^^^^^^^^^^^^^^^
+The 'eval', 'sys' and 'sys2' block macros exhibit the same behavior as
+their same named <<X24, system attribute references>>. The difference
+is that system macros occur in a block macro context whereas system
+attributes are confined to inline contexts where attribute
+substitution is enabled.
+
+The following example displays a long directory listing inside a
+literal block:
+
+  ------------------
+  sys::ls -l *.txt
+  ------------------
+
+NOTE: There are no block macro versions of the 'eval3' and 'sys3'
+system attributes.
+
+Template System Macro
+^^^^^^^^^^^^^^^^^^^^^
+The `template` block macro allows the inclusion of one configuration
+file template section within another.  The following example includes
+the `admonitionblock` section in the `admonitionparagraph`
+section:
+
+  admonitionparagraph
+  template::admonitionblock
+
+.Template macro behavior
+- The `template::` macro is useful for factoring configuration file
+  markup.
+- `template::` macros cannot be nested.
+- `template::` macro expansion is applied after all configuration
+  files have been read.
+
+
+X77
+Passthrough macros
+~~~~~~~~~~~~~~~~~~
+Passthrough macros are analogous to <<X76,passthrough blocks>> and are
+used to pass text directly to the output. The substitution performed
+on the text is determined by the macro definition but can be overridden
+by the `<subslist>`.  The usual syntax is
+`<name>:<subslist><passtext>` (for inline macros) and
+`<name>::<subslist><passtext>` (for block macros). Passthroughs, by
+definition, take precedence over all other text substitutions.
+
+pass::
+  Inline and block. Passes text unmodified (apart from explicitly
+  specified substitutions). Examples:
+
+  pass:<q>To be or not to be</q>
+  pass:attributes,quotes<u>the '{author}'</u>
+
+asciimath, latexmath::
+  Inline and block. Passes text unmodified.  Used for
+  <<X78,mathematical formulas>>.
+
+\+++::
+  Inline and block. The triple-plus passthrough is functionally
+  identical to the 'pass' macro but you don't have to escape ``
+  characters and you can prefix with quoted attributes in the inline
+  version. Example:
+
+  Red red+++`sum_(i=1)\^n i=(n(n+1))/2`$+++ AsciiMath formula
+
+$$::
+  Inline and block. The double-dollar passthrough is functionally
+  identical to the triple-plus passthrough with one exception: special
+  characters are escaped. Example:
+
+  $$`a,b,c,d((n),(k))`$$
+
+X80`::
+  Text quoted with single backtick characters constitutes an 'inline
+  literal' passthrough. The enclosed text is rendered in a monospaced
+  font and is only subject to special character substitution.  This
+  makes sense since monospace text is usually intended to be rendered
+  literally and often contains characters that would otherwise have to
+  be escaped. If you need monospaced text containing inline
+  substitutions use a <<X81,plus character instead of a backtick>>.
+
+Macro Definitions
+~~~~~~~~~~~~~~~~~
+Each entry in the configuration `macros` section is a macro
+definition which can take one of the following forms:
+
+`<pattern>=<name><subslist`:: Inline macro definition.
+`<pattern>=#<name><subslist`:: Block macro definition.
+`<pattern>=+<name><subslist`:: System macro definition.
+`<pattern>`:: Delete the existing macro with this `<pattern>`.
+
+`<pattern>` is a Python regular expression and `<name>` is the name of
+a markup template. If `<name>` is omitted then it is the value of the
+regular expression match group named 'name'.  The optional
+`<subslist` is a comma-separated list of substitution names enclosed
+in `` brackets, it sets the default substitutions for passthrough
+text, if omitted then no passthrough substitutions are performed.
+
+.Pattern named groups
+The following named groups can be used in macro `<pattern>` regular
+expressions and are available as markup template attributes:
+
+name::
+  The macro name.
+
+target::
+  The macro target.
+
+attrlist::
+  The macro attribute list.
+
+passtext::
+  Contents of this group are passed unmodified to the output subject
+  only to 'subslist' substitutions.
+
+subslist::
+  Processed as a comma-separated list of substitution names for
+  'passtext' substitution, overrides the the macro definition
+  'subslist'.
+
+.Here's what happens during macro substitution
+- Each contextually relevant macro 'pattern' from the `macros`
+  section is matched against the input source line.
+- If a match is found the text to be substituted is loaded from a
+  configuration markup template section named like
+  `<name>-inlinemacro` or `<name>-blockmacro` (depending on the macro
+  type).
+- Global and macro attribute list attributes are substituted in the
+  macro's markup template.
+- The substituted template replaces the macro reference in the output
+  document.
+
+
+X98
+HTML 5 audio and video block macros
+-----------------------------------
+The 'html5' backend 'audio' and 'video' block macros generate the HTML
+5 'audio' and 'video' elements respectively.  They follow the usual
+AsciiDoc block macro syntax `<name>::<target><attrlist>` where:
+
+horizontal
+`<name>`:: 'audio' or 'video'.
+`<target>`:: The URL or file name of the video or audio file.
+`<attrlist>`:: A list of named attributes (see below).
+
+.Audio macro attributes
+options="header",cols="1,5",frame="topbot"
+|====================================================================
+|Name | Value
+|options
+|A comma separated list of one or more of the following items:
+'autoplay', 'loop' which correspond to the same-named HTML 5 'audio'
+element boolean attributes.  By default the player 'controls' are
+enabled, include the 'nocontrols' option value to hide them.
+|====================================================================
+
+.Video macro attributes
+options="header",cols="1,5",frame="topbot"
+|====================================================================
+|Name   | Value
+|height | The height of the player in pixels.
+|width  | The width of the player in pixels.
+|poster | The URL or file name of an image representing the video.
+|options
+|A comma separated list of one or more of the following items:
+'autoplay', 'loop' and 'nocontrols'. The 'autoplay' and 'loop' options
+correspond to the same-named HTML 5 'video' element boolean
+attributes.  By default the player 'controls' are enabled, include the
+'nocontrols' option value to hide them.
+|====================================================================
+
+Examples:
+
+---------------------------------------------------------------------
+audio::images/example.ogg
+
+video::gizmo.ogvwidth=200,options="nocontrols,autoplay"
+
+.Example video
+video::gizmo.ogv
+
+video::http://www.808.dk/pics/video/gizmo.ogv
+---------------------------------------------------------------------
+
+If your needs are more complex put raw HTML 5 in a markup block, for
+example (from http://www.808.dk/?code-html-5-video):
+
+---------------------------------------------------------------------
+++++
+<video poster="pics/video/gizmo.jpg" id="video" style="cursor: pointer;" >
+  <source src="pics/video/gizmo.mp4" />
+  <source src="pics/video/gizmo.webm" type="video/webm" />

+  Video not playing? <a href="pics/video/gizmo.mp4">Download file</a> instead.
+</video>
+
+<script type="text/javascript">
+  var video = document.getElementById('video');
+  video.addEventListener('click',function(){
+    video.play();
+  },false);
+</script>
+++++
+---------------------------------------------------------------------
+
+
+Tables
+------
+The AsciiDoc table syntax looks and behaves like other delimited block
+types and supports standard <<X73,block configuration entries>>.
+Formatting is easy to read and, just as importantly, easy to enter.
+
+- Cells and columns can be formatted using built-in customizable styles.
+- Horizontal and vertical cell alignment can be set on columns and
+  cell.
+- Horizontal and vertical cell spanning is supported.
+
+.Use tables sparingly
+*********************************************************************
+When technical users first start creating documents, tables (complete
+with column spanning and table nesting) are often considered very
+important. The reality is that tables are seldom used, even in
+technical documentation.
+
+Try this exercise: thumb through your library of technical books,
+you'll be surprised just how seldom tables are actually used, even
+less seldom are tables containing block elements (such as paragraphs
+or lists) or spanned cells. This is no accident, like figures, tables
+are outside the normal document flow -- tables are for consulting not
+for reading.
+
+Tables are designed for, and should normally only be used for,
+displaying column oriented tabular data.

+Table input data formats
+~~~~~~~~~~~~~~~~~~~~~~~~
+AsciiDoc table data can be 'psv', 'dsv' or 'csv' formatted.  The
+default table format is 'psv'.
+
+AsciiDoc 'psv' ('Prefix Separated Values') and 'dsv' ('Delimiter
+Separated Values') formats are cell oriented -- the table is treated
+as a sequence of cells -- there are no explicit row separators.
+
+- 'psv' prefixes each cell with a separator whereas 'dsv' delimits
+  cells with a separator.
+- 'psv' and 'dsv' separators are Python regular expressions.
+- The default 'psv' separator contains <<X84, cell specifier>> related
+  named regular expression groups.
+- The default 'dsv' separator is `:|\n` (a colon or a new line
+  character).
+- 'psv' and 'dsv' cell separators can be escaped by preceding them
+  with a backslash character.
+
+Here are four 'psv' cells (the second item spans two columns; the
+last contains an escaped separator):
+
+  |One 2+|Two and three |A \| separator character
+
+'csv'  is the quasi-standard row oriented 'Comma Separated Values
+(CSV)' format commonly used to import and export spreadsheet and
+database data.
+
+X69
+Table attributes
+~~~~~~~~~~~~~~~~
+Tables can be customized by the following attributes:
+
+format::
+'psv' (default), 'dsv' or 'csv' (See <<X68, Table Data Formats>>).
+
+separator::
+The cell separator. A Python regular expression ('psv' and 'dsv'
+formats) or a single character ('csv' format).
+
+frame::
+Defines the table border and can take the following values: 'topbot'
+(top and bottom), 'all' (all sides), 'none' and 'sides' (left and
+right sides). The default value is 'all'.
+
+grid::
+Defines which ruler lines are drawn between table rows and columns.
+The 'grid' attribute value can be any of the following values: 'none',
+'cols', 'rows' and 'all'. The default value is 'all'.
+
+align::
+Use the 'align' attribute to horizontally align the table on the
+page (works with HTML outputs only, has no effect on DocBook outputs).
+The following values are valid: 'left', 'right', and 'center'.
+
+float::
+Use the 'float' attribute to float the table 'left' or 'right' on the
+page (works with HTML outputs only, has no effect on DocBook outputs).
+Floating only makes sense in conjunction with a table 'width'
+attribute value of less than 100% (otherwise the table will take up
+all the available space).  'float' and 'align' attributes are mutually
+exclusive.  Use the `unfloat::` block macro to stop floating.
+
+halign::
+Use the 'halign' attribute to horizontally align all cells in a table.
+The following values are valid: 'left', 'right', and 'center'
+(defaults to 'left'). Overridden by <<X70,Column specifiers>>  and
+<<X84,Cell specifiers>>.
+
+valign::
+Use the 'valign' attribute to vertically align all cells in a table.
+The following values are valid: 'top', 'bottom', and 'middle'
+(defaults to 'top'). Overridden by <<X70,Column specifiers>>  and
+<<X84,Cell specifiers>>.
+
+options::
+The 'options' attribute can contain comma separated values, for
+example: 'header', 'footer'. By default header and footer rows are
+omitted.  See <<X74,attribute options>> for a complete list of
+available table options.
+
+cols::
+The 'cols' attribute is a comma separated list of <<X70,column
+specifiers>>. For example `cols="2<p,2*,4p,>"`.
+
+- If 'cols' is present it must specify all columns.
+- If the 'cols' attribute is not specified the number of columns is
+  calculated as the number of data items in the *first line* of the
+  table.
+- The degenerate form for the 'cols' attribute is an integer
+  specifying the number of columns e.g. `cols=4`.
+
+width::
+The 'width' attribute is expressed as a percentage value
+('"1%"'...'"99%"'). The width specifies the table width relative to
+the available width. HTML backends use this value to set the table
+width attribute. It's a bit more complicated with DocBook, see the
+<<X89,DocBook table widths>> sidebar.
+
+filter::
+The 'filter' attribute defines an external shell command that is
+invoked for each cell. The built-in 'asciidoc' table style is
+implemented using a filter.
+
+X89
+.DocBook table widths
+**********************************************************************
+The AsciiDoc docbook backend generates CALS tables. CALS tables do not
+support a table width attribute -- table width can only be controlled
+by specifying absolute column widths.
+
+Specifying absolute column widths is not media independent because
+different presentation media have different physical dimensions. To
+get round this limitation both
+http://www.sagehill.net/docbookxsl/Tables.html#TableWidthDocBook XSL
+Stylesheets and
+http://dblatex.sourceforge.net/doc/manual/ch03s05.html#sec-table-widthdblatex
+have implemented table width processing instructions for setting the
+table width as a percentage of the available width. AsciiDoc emits
+these processing instructions if the 'width' attribute is set along
+with proportional column widths (the AsciiDoc docbook backend
+'pageunits' attribute defaults to '*').
+
+To generate DocBook tables with absolute column widths set the
+'pageunits' attribute to a CALS absolute unit such as 'pt' and set the
+'pagewidth' attribute to match the width of the presentation media.
+**********************************************************************
+
+X70
+Column Specifiers
+~~~~~~~~~~~~~~~~~
+Column specifiers define how columns are rendered and appear in the
+table <<X69,cols attribute>>.  A column specifier consists of an
+optional column multiplier followed by optional alignment, width and
+style values and is formatted like:
+
+  <multiplier>*<align><width><style>
+
+- All components are optional. The multiplier must be first and the
+  style last. The order of `<align>` or `<width>` is not important.
+- Column `<width>` can be either an integer proportional value (1...)
+  or a percentage (1%...100%). The default value is 1. To ensure
+  portability across different backends, there is no provision for
+  absolute column widths (not to be confused with output column width
+  <<X72,markup attributes>> which are available in both percentage and
+  absolute units).
+- The '<align>' column alignment specifier is formatted like:
+
+  <horizontal>.<vertical>
++
+Where `<horizontal>` and `<vertical>` are one of the following
+characters: `<`, `^` or `>` which represent 'left', 'center' and
+'right' horizontal alignment or 'top', 'middle' and 'bottom' vertical
+alignment respectively.
+
+- A `<multiplier>` can be used to specify repeated columns e.g.
+  `cols="4*<"` specifies four left-justified columns. The default
+  multiplier value is 1.
+- The `<style>` name specifies a <<X71,table style>> to used to markup
+  column cells (you can use the full style names if you wish but the
+  first letter is normally sufficient).
+- Column specific styles are not applied to header rows.
+
+X84
+Cell Specifiers
+~~~~~~~~~~~~~~~
+Cell specifiers allow individual cells in 'psv' formatted tables to be
+spanned, multiplied, aligned and styled.  Cell specifiers prefix 'psv'
+`|` delimiters and are formatted like:
+
+  <span>*|+<align><style>
+
+- '<span>' specifies horizontal and vertical cell spans ('+' operator) or
+  the number of times the cell is replicated ('*' operator). '<span>'
+  is formatted like:
+
+  <colspan>.<rowspan>
++
+Where `<colspan>` and `<rowspan>` are integers specifying the number of
+columns and rows to span.
+
+- `<align>` specifies horizontal and vertical cell alignment an is the
+  same as in <<X70,column specifiers>>.
+- A `<style>` value is the first letter of <<X71,table style>> name.
+
+For example, the following 'psv' formatted cell will span two columns
+and the text will be centered and emphasized:
+
+  `2+^e| Cell text`
+
+X71
+Table styles
+~~~~~~~~~~~~
+Table styles can be applied to the entire table (by setting the
+'style' attribute in the table's attribute list) or on a per column
+basis (by specifying the style in the table's <<X69,cols attribute>>).
+Table data can be formatted using the following predefined styles:
+
+default::
+The default style: AsciiDoc inline text formatting; blank lines are
+treated as paragraph breaks.
+
+emphasis::
+Like default but all text is emphasised.
+
+monospaced::
+Like default but all text is in a monospaced font.
+
+strong::
+Like default but all text is bold.
+
+header::
+Apply the same style as the table header. Normally used to create a
+vertical header in the first column.
+
+asciidoc::
+With this style table cells can contain any of the AsciiDoc elements
+that are allowed inside document sections. This style runs asciidoc(1)
+as a filter to process cell contents. See also <<X83,Docbook table
+limitations>>.
+
+literal::
+No text formatting; monospaced font; all line breaks are retained
+(the same as the AsciiDoc <<X65,LiteralBlock>> element).
+
+verse::
+All line breaks are retained (just like the AsciiDoc <<X94,verse
+paragraph style>>).
+
+X72
+Markup attributes
+~~~~~~~~~~~~~~~~~
+AsciiDoc makes a number of attributes available to table markup
+templates and tags. Column specific attributes are available when
+substituting the 'colspec' cell data tags.
+
+pageunits::
+DocBook backend only. Specifies table column absolute width units.
+Defaults to '*'.
+
+pagewidth::
+DocBook backend only. The nominal output page width in 'pageunit'
+units. Used to calculate CALS tables absolute column and table
+widths. Defaults to '425'.
+
+tableabswidth::
+Integer value calculated from 'width' and 'pagewidth' attributes.
+In 'pageunit' units.
+
+tablepcwidth::
+Table width expressed as a percentage of the available width. Integer
+value (0..100).
+
+colabswidth::
+Integer value calculated from 'cols' column width, 'width' and
+'pagewidth' attributes.  In 'pageunit' units.
+
+colpcwidth::
+Column width expressed as a percentage of the table width. Integer
+value (0..100).
+
+colcount::
+Total number of table columns.
+
+rowcount::
+Total number of table rows.
+
+halign::
+Horizontal cell content alignment: 'left', 'right' or 'center'.
+
+valign::
+Vertical cell content alignment: 'top', 'bottom' or 'middle'.
+
+colnumber, colstart::
+The number of the leftmost column occupied by the cell (1...).
+
+colend::
+The number of the rightmost column occupied by the cell (1...).
+
+colspan::
+Number of columns the cell should span.
+
+rowspan::
+Number of rows the cell should span (1...).
+
+morerows::
+Number of additional rows the cell should span (0...).
+
+Nested tables
+~~~~~~~~~~~~~
+An alternative 'psv' separator character '!' can be used (instead of
+'|') in nested tables. This allows a single level of table nesting.
+Columns containing nested tables must use the 'asciidoc' style. An
+example can be found in `./examples/website/newtables.txt`.
+
+X83
+DocBook table limitations
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Fully implementing tables is not trivial, some DocBook toolchains do
+better than others.  AsciiDoc HTML table outputs are rendered
+correctly in all the popular browsers -- if your DocBook generated
+tables don't look right compare them with the output generated by the
+AsciiDoc 'xhtml11' backend or try a different DocBook toolchain.  Here
+is a list of things to be aware of:
+
+- Although nested tables are not legal in DocBook 4 the FOP and
+  dblatex toolchains will process them correctly.  If you use `a2x(1)`
+  you will need to include the `--no-xmllint` option to suppress
+  DocBook validation errors.
++
+NOTE: In theory you can nest DocBook 4 tables one level using the
+'entrytbl' element, but not all toolchains process 'entrytbl'.
+
+- DocBook only allows a subset of block elements inside table cells so
+  not all AsciiDoc elements produce valid DocBook inside table cells.
+  If you get validation errors running `a2x(1)` try the `--no-xmllint`
+  option, toolchains will often process nested block elements such as
+  sidebar blocks and floating titles correctly even though, strictly
+  speaking, they are not legal.
+
+- Text formatting in cells using the 'monospaced' table style will
+  raise validation errors because the DocBook 'literal' element was
+  not designed to support formatted text (using the 'literal' element
+  is a kludge on the part of AsciiDoc as there is no easy way to set
+  the font style in DocBook.
+
+- Cell alignments are ignored for 'verse', 'literal' or 'asciidoc'
+  table styles.
+
+
+X1
+Manpage Documents
+-----------------
+Sooner or later, if you program in a UNIX environment, you're going
+to have to write a man page.
+
+By observing a couple of additional conventions (detailed below) you
+can write AsciiDoc files that will generate HTML and PDF man pages
+plus the native manpage roff format.  The easiest way to generate roff
+manpages from AsciiDoc source is to use the a2x(1) command. The
+following example generates a roff formatted manpage file called
+`asciidoc.1` (a2x(1) uses asciidoc(1) to convert `asciidoc.1.txt` to
+DocBook which it then converts to roff using DocBook XSL Stylesheets):
+
+  a2x --doctype manpage --format manpage asciidoc.1.txt
+
+.Viewing and printing manpage files
+**********************************************************************
+Use the `man(1)` command to view the manpage file:
+
+  $ man -l asciidoc.1
+
+To print a high quality man page to a postscript printer:
+
+  $ man -l -Tps asciidoc.1 | lpr
+
+You could also create a PDF version of the man page by converting
+PostScript to PDF using `ps2pdf(1)`:
+
+  $ man -l -Tps asciidoc.1 | ps2pdf - asciidoc.1.pdf
+
+The `ps2pdf(1)` command is included in the Ghostscript distribution.
+**********************************************************************
+
+To find out more about man pages view the `man(7)` manpage
+(`man 7 man` and `man man-pages` commands).
+
+
+Document Header
+~~~~~~~~~~~~~~~
+A manpage document Header is mandatory. The title line contains the
+man page name followed immediately by the manual section number in
+brackets, for example 'ASCIIDOC(1)'. The title name should not contain
+white space and the manual section number is a single digit optionally
+followed by a single character.
+
+The NAME Section
+~~~~~~~~~~~~~~~~
+The first manpage section is mandatory, must be titled 'NAME' and must
+contain a single paragraph (usually a single line) consisting of a
+list of one or more comma separated command name(s) separated from the
+command purpose by a dash character. The dash must have at least one
+white space character on either side. For example:
+
+  printf, fprintf, sprintf - print formatted output
+
+The SYNOPSIS Section
+~~~~~~~~~~~~~~~~~~~~
+The second manpage section is mandatory and must be titled 'SYNOPSIS'.
+
+refmiscinfo attributes
+~~~~~~~~~~~~~~~~~~~~~~
+In addition to the automatically created man page <<X60,intrinsic
+attributes>> you can assign DocBook
+https://tdg.docbook.org/tdg/4.5/refmiscinfo.htmlrefmiscinfo
+element 'source', 'version' and 'manual' values using AsciiDoc
+`{mansource}`, `{manversion}` and `{manmanual}` attributes
+respectively. This example is from the AsciiDoc header of a man page
+source file:
+
+  :man source:   AsciiDoc
+  :man version:  {revnumber}
+  :man manual:   AsciiDoc Manual
+
+
+X78
+Mathematical Formulas
+---------------------
+The 'asciimath' and 'latexmath' <<X76,passthrough blocks>> along with
+the 'asciimath' and 'latexmath' <<X77,passthrough macros>> provide a
+(backend dependent) mechanism for rendering mathematical formulas. You
+can use the following math markups:
+
+LaTeX Math
+~~~~~~~~~~
+ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdfLaTeX
+math can be included in documents that are processed by
+<<X31,dblatex(1)>>.  Example inline formula:
+
+  latexmath:$C = \alpha + \beta Y^{\gamma} + \epsilon$
+
+For more examples see the {website}AsciiDoc website or the
+distributed `doc/latexmath.txt` file.
+
+MathJax
+~~~~~~~
+https://www.mathjax.org/MathJax allows LaTeX Math style formulas to be included
+in XHTML documents generated via the AsciiDoc 'xhtml11' and 'html5' backends.
+This route overcomes several restrictions of the MathML-based approaches,
+notably, restricted support of MathML by many mainstream browsers. To enable
+'MathJax' support you must define the 'mathjax' attribute, for example using the
+`-a mathjax` command-line option. Equations are specified as explained above
+using the 'latexmath' passthrough blocks. By default, rendering of equations
+with 'MathJax' requires a working internet connection and will thus not work if
+you are offline (but it can be configured differently).
+
+LaTeXMathML
+~~~~~~~~~~~
+/////////////////////////////////////////////////////////////////////
+There is an https://math.etsu.edu/LaTeXMathML/extended LaTeXMathML
+version by Jeff Knisley, in addition to a JavaScript file it requires
+the inclusion of a CSS file.
+/////////////////////////////////////////////////////////////////////
+
+'LaTeXMathML' allows LaTeX Math style formulas to be included in XHTML
+documents generated using the AsciiDoc 'xhtml11' and 'html5' backends.
+AsciiDoc uses the
+https://www.maths.nottingham.ac.uk/plp/pmadw/lm.htmloriginal
+LaTeXMathML by Douglas Woodall.  'LaTeXMathML' is derived from
+ASCIIMath and is for users who are more familiar with or prefer
+using LaTeX math formulas (it recognizes a subset of LaTeX Math, the
+differences are documented on the 'LaTeXMathML' web page).  To enable
+LaTeXMathML support you must define the 'latexmath' attribute, for
+example using the `-a latexmath` command-line option.  Example inline
+formula:
+
+  latexmath:$\sum_{n=1}^\infty \frac{1}{2^n}$
+
+For more examples see the {website}AsciiDoc website or the
+distributed `doc/latexmathml.txt` file.
+
+NOTE: The 'latexmath' macro used to include 'LaTeX Math' in DocBook
+outputs is not the same as the 'latexmath' macro used to include
+'LaTeX MathML' in XHTML outputs.  'LaTeX Math' applies to DocBook
+outputs that are processed by <<X31,dblatex>> and is normally used to
+generate PDF files.  'LaTeXMathML' is very much a subset of 'LaTeX
+Math' and applies to XHTML documents. This remark does not
+apply to 'MathJax' which does not use any of the 'latexmath' macros
+(but only requires the 'latexmath' passthrough blocks for identification
+of the equations).
+
+ASCIIMath
+~~~~~~~~~~~
+/////////////////////////////////////////////////////////////////////
+The older ASCIIMath 1.47 version is used instead of version 2
+because:
+
+1. Version 2 doesn't work when embedded.
+2. Version 2 is much larger.
+/////////////////////////////////////////////////////////////////////
+
+http://asciimath.org/ASCIIMath formulas can be included in XHTML
+documents generated using the 'xhtml11' and 'html5' backends. To enable
+ASCIIMath support you must define the 'asciimath' attribute, for
+example using the `-a asciimath` command-line option.  Example inline
+formula:
+
+  asciimath:`x/x={(1,if x!=0),(text{undefined},if x=0):}`
+
+For more examples see the {website}AsciiDoc website or the
+distributed `doc/asciimath.txt` file.
+
+MathML
+~~~~~~
+https://www.w3.org/Math/MathML is a low level XML markup for
+mathematics. AsciiDoc has no macros for MathML but users familiar with
+this markup could use passthrough macros and passthrough blocks to
+include MathML in output documents.
+
+
+X7
+Configuration Files
+-------------------
+AsciiDoc source file syntax and output file markup is largely
+controlled by a set of cascading, text based, configuration files.  At
+runtime The AsciiDoc default configuration files are combined with
+optional user and document specific configuration files.
+
+Configuration File Format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Configuration files contain named sections. Each section begins with a
+section name in square brackets . The section body consists of the
+lines of text between adjacent section headings.
+
+- Section names consist of one or more alphanumeric, underscore or
+  dash characters and cannot begin or end with a dash.
+- Lines starting with a '#' character are treated as comments and
+  ignored.
+- If the section name is prefixed with a '+' character then the
+  section contents is appended to the contents of an already existing
+  same-named section.
+- Otherwise same-named sections and section entries override
+  previously loaded sections and section entries (this is sometimes
+  referred to as 'cascading').  Consequently, downstream configuration
+  files need only contain those sections and section entries that need
+  to be overridden.
+
+TIP: When creating custom configuration files you only need to include
+the sections and entries that differ from the default configuration.
+
+TIP: The best way to learn about configuration files is to read the
+default configuration files in the AsciiDoc distribution in
+conjunction with asciidoc(1) output files. You can view configuration
+file load sequence by turning on the asciidoc(1) `-v` (`--verbose`)
+command-line option.
+
+AsciiDoc reserves the following section names for specific purposes:
+
+miscellaneous::
+        Configuration options that don't belong anywhere else.
+attributes::
+        Attribute name/value entries.
+specialcharacters::
+        Special characters reserved by the backend markup.
+tags::
+        Backend markup tags.
+quotes::
+        Definitions for quoted inline character formatting.
+specialwords::
+        Lists of words and phrases singled out for special markup.
+replacements, replacements2, replacements3::
+        Find and replace substitution definitions.
+specialsections::
+        Used to single out special section names for specific markup.
+macros::
+        Macro syntax definitions.
+titles::
+        Heading, section and block title definitions.
+paradef-*::
+        Paragraph element definitions.
+blockdef-*::
+        DelimitedBlock element definitions.
+listdef-*::
+        List element definitions.
+listtags-*::
+        List element tag definitions.
+tabledef-*::
+        Table element definitions.
+tabletags-*::
+        Table element tag definitions.
+
+Each line of text in these sections is a 'section entry'. Section
+entries share the following syntax:
+
+name=value::
+        The entry value is set to value.
+name=::
+        The entry value is set to a zero length string.
+name!::
+        The entry is undefined (deleted from the configuration). This
+        syntax only applies to 'attributes' and 'miscellaneous'
+        sections.
+
+.Section entry behavior
+- All equals characters inside the `name` must be escaped with a
+  backslash character.
+- `name` and `value` are stripped of leading and trailing white space.
+- Attribute names, tag entry names and markup template section names
+  consist of one or more alphanumeric, underscore or dash characters.
+  Names should not begin or end with a dash.
+- A blank configuration file section (one without any entries) deletes
+  any preceding section with the same name (applies to non-markup
+  template sections).
+
+
+Miscellaneous section
+~~~~~~~~~~~~~~~~~~~~~
+The optional `miscellaneous` section specifies the following
+`name=value` options:
+
+newline::
+        Output file line termination characters. Can include any
+        valid Python string escape sequences. The default value is
+        `\r\n` (carriage return, line feed). Should not be quoted or
+        contain explicit spaces (use `\x20` instead). For example:
+
+        $ asciidoc -a 'newline=\n' -b docbook mydoc.txt
+
+outfilesuffix::
+        The default extension for the output file, for example
+        `outfilesuffix=.html`. Defaults to backend name.
+tabsize::
+        The number of spaces to expand tab characters, for example
+        `tabsize=4`. Defaults to 8. A 'tabsize' of zero suppresses tab
+        expansion (useful when piping included files through block
+        filters). Included files can override this option using the
+        'tabsize' attribute.
+pagewidth, pageunits::
+        These global table related options are documented in the
+        <<X4,Table Configuration File Definitions>> sub-section.
+
+NOTE: `miscellaneous` configuration file entries can be set using
+the asciidoc(1) `-a` (`--attribute`) command-line option.
+
+Titles section
+~~~~~~~~~~~~~~
+sectiontitle::
+        Two line section title pattern. The entry value is a Python
+        regular expression containing the named group 'title'.
+
+underlines::
+        A comma separated list of document and section title underline
+        character pairs starting with the section level 0 and ending
+        with section level 4 underline. The default setting is:
+
+        underlines="==","--","~~","^^","++"
+
+sect0...sect4::
+        One line section title patterns. The entry value is a Python
+        regular expression containing the named group 'title'.
+
+blocktitle::
+        <<X42,BlockTitle element>> pattern.  The entry value is a
+        Python regular expression containing the named group 'title'.
+
+subs::
+        A comma separated list of substitutions that are performed on
+        the document header and section titles. Defaults to 'normal'
+        substitution.
+
+Tags section
+~~~~~~~~~~~~
+The `tags` section contains backend tag definitions (one per
+line). Tags are used to translate AsciiDoc elements to backend
+markup.
+
+An AsciiDoc tag definition is formatted like
+`<tagname>=<starttag>|<endtag>`. For example:
+
+  emphasis=<em>|</em>
+
+In this example asciidoc(1) replaces the | character with the
+emphasized text from the AsciiDoc input file and writes the result to
+the output file.
+
+Use the `{brvbar}` attribute reference if you need to include a | pipe
+character inside tag text.
+
+Attributes section
+~~~~~~~~~~~~~~~~~~
+The optional `attributes` section contains predefined attributes.
+
+If the attribute value requires leading or trailing spaces then the
+text text should be enclosed in quotation mark (") characters.
+
+To delete a attribute insert a `name!` entry in a downstream
+configuration file or use the asciidoc(1) `--attribute name!`
+command-line option (an attribute name suffixed with a `!` character
+deletes the attribute)
+
+Special Characters section
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+The `specialcharacters` section specifies how to escape characters
+reserved by the backend markup. Each translation is specified on a
+single line formatted like:
+
+  <special_character>=<translated_characters>
+
+Special characters are normally confined to those that resolve
+markup ambiguity (in the case of HTML and XML markups the ampersand,
+less than and greater than characters).  The following example causes
+all occurrences of the `<` character to be replaced by `&lt;`.
+
+  <=&lt;
+
+Quoted Text section
+~~~~~~~~~~~~~~~~~~~
+Quoting is used primarily for text formatting.  The `quotes` section
+defines AsciiDoc quoting characters and their corresponding backend
+markup tags.  Each section entry value is the name of a of a `tags`
+section entry. The entry name is the character (or characters) that
+quote the text.  The following examples are taken from AsciiDoc
+configuration files:
+
+  quotes
+  _=emphasis
+
+  tags
+  emphasis=<em>|</em>
+
+You can specify the left and right quote strings separately by
+separating them with a | character, for example:
+
+  ``|''=quoted
+
+Omitting the tag will disable quoting, for example, if you don't want
+superscripts or subscripts put the following in a custom configuration
+file or edit the global `asciidoc.conf` configuration file:
+
+  quotes
+  ^=
+  ~=
+
+<<X52,Unconstrained quotes>> are differentiated from constrained
+quotes by prefixing the tag name with a hash character, for example:
+
+  __=#emphasis
+
+.Quoted text behavior
+- Quote characters must be non-alphanumeric.
+- To minimize quoting ambiguity try not to use the same quote
+  characters in different quote types.
+
+Special Words section
+~~~~~~~~~~~~~~~~~~~~~
+The `specialwords` section is used to single out words and phrases
+that you want to consistently format in some way throughout your
+document without having to repeatedly specify the markup. The name of
+each entry corresponds to a markup template section and the entry
+value consists of a list of words and phrases to be marked up. For
+example:
+
+  specialwords
+  strongwords=NOTE IMPORTANT
+
+  strongwords
+  <strong>{words}</strong>
+
+The examples specifies that any occurrence of `NOTE` or `IMPORTANT`
+should appear in a bold font.
+
+Words and word phrases are treated as Python regular expressions: for
+example, the word `^NOTE` would only match `NOTE` if appeared at
+the start of a line.
+
+AsciiDoc comes with three built-in Special Word types:
+'emphasizedwords', 'monospacedwords' and 'strongwords', each has a
+corresponding (backend specific) markup template section. Edit the
+configuration files to customize existing Special Words and to add new
+ones.
+
+.Special word behavior
+- Word list entries must be separated by space characters.
+- Word list entries with embedded spaces should be enclosed in quotation (")
+  characters.
+- A `specialwords` section entry of the form
+  +name=word1{nbsp}word2...+ adds words to existing `name` entries.
+- A `specialwords` section entry of the form `name` undefines
+  (deletes) all existing `name` words.
+- Since word list entries are processed as Python regular expressions
+  you need to be careful to escape regular expression special
+  characters.
+- By default Special Words are substituted before Inline Macros, this
+  may lead to undesirable consequences. For example the special word
+  `foobar` would be expanded inside the macro call
+  `http://www.foobar.com`.  A possible solution is to emphasize
+  whole words only by defining the word using regular expression
+  characters, for example `\bfoobar\b`.
+- If the first matched character of a special word is a backslash then
+  the remaining characters are output without markup i.e. the
+  backslash can be used to escape special word markup.  For example
+  the special word `\\?\bTten\b` will mark up the words `Ten` and
+  `ten` only if they are not preceded by a backslash.
+
+X10
+Replacements section
+~~~~~~~~~~~~~~~~~~~~
+`replacements`, `replacements2` and `replacements3`
+configuration file entries specify find and replace text and are
+formatted like:
+
+  <find_pattern>=<replacement_text>
+
+The find text can be a Python regular expression; the replace text can
+contain Python regular expression group references.
+
+Use Replacement shortcuts for often used macro references, for
+example (the second replacement allows us to backslash escape the
+macro name):
+
+  NEW!=image:./images/smallnew.pngNew!
+  \\NEW!=NEW!
+
+The only difference between the three replacement types is how they
+are applied. By default 'replacements' and 'replacements2' are applied
+in <<X102,normal>> substitution contexts whereas 'replacements3' needs
+to be configured explicitly and should only be used in backend
+configuration files.
+
+.Replacement behavior
+- The built-in replacements can be escaped with a backslash.
+- If the find or replace text has leading or trailing spaces then the
+  text should be enclosed in quotation (") characters.
+- Since the find text is processed as a regular expression you need to
+  be careful to escape regular expression special characters.
+- Replacements are performed in the same order they appear in the
+  configuration file replacements section.
+
+Markup Template Sections
+~~~~~~~~~~~~~~~~~~~~~~~~
+Markup template sections supply backend markup for translating
+AsciiDoc elements.  Since the text is normally backend dependent
+you'll find these sections in the backend specific configuration
+files. Template sections differ from other sections in that they
+contain a single block of text instead of per line 'name=value'
+entries. A markup template section body can contain:
+
+- Attribute references
+- System macro calls.
+- A document content placeholder
+
+The document content placeholder is a single | character and is
+replaced by text from the source element.  Use the `{brvbar}`
+attribute reference if you need a literal | character in the template.
+
+X27
+Configuration file names, precedence and locations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Configuration files have a `.conf` file name extension; they are
+loaded from the following locations:
+
+1. The directory containing the asciidoc executable.
+2. If there is no `asciidoc.conf` file in the directory containing the
+   asciidoc executable then load from the global configuration
+   directory (normally `/etc/asciidoc` or `/usr/local/etc/asciidoc`)
+   i.e. the global configuration files directory is skipped if
+   AsciiDoc configuration files are installed in the same directory as
+   the asciidoc executable. This allows both a system wide copy and
+   multiple local copies of AsciiDoc to coexist on the same host PC.
+3. The user's `$HOME/.asciidoc` directory (if it exists).
+4. The directory containing the AsciiDoc source file.
+5. Explicit configuration files specified using:
+   - The `conf-files` attribute (one or more file names separated by a
+     `|` character). These files are loaded in the order they are
+     specified and prior to files specified using the `--conf-file`
+     command-line option.
+   - The asciidoc(1) `--conf-file`) command-line option.  The
+     `--conf-file` option can be specified multiple times, in which
+     case configuration files will be processed in the same order they
+     appear on the command-line.
+6. <<X100,Backend plugin>> configuration files are loaded from
+   subdirectories named like `backends/<backend>` in locations 1, 2
+   and 3.
+7. <<X59,Filter>> configuration files are loaded from subdirectories
+   named like `filters/<filter>` in locations 1, 2 and 3.
+
+Configuration files from the above locations are loaded in the
+following order:
+
+- The `attributes` section only from:
+  * `asciidoc.conf` in location 3
+  * Files from location 5.
++
+This first pass makes locally set attributes available in the global
+`asciidoc.conf` file.
+
+- `asciidoc.conf` from locations 1, 2, 3.
+- 'attributes', 'titles' and 'specialcharacters' sections from the
+  `asciidoc.conf` in location 4.
+- The document header is parsed at this point and we can assume the
+  'backend' and 'doctype' have now been defined.
+- Backend plugin `<backend>.conf` and `<backend>-<doctype>.conf` files
+  from locations 6.  If a backend plugin is not found then try
+  locations 1, 2 and 3 for `<backend>.conf` and
+  `<backend>-<doctype>.conf` backend configuration files.
+- Filter conf files from locations 7.
+- `lang-<lang>.conf` from locations 1, 2, 3.
+- `asciidoc.conf` from location 4.
+- `<backend>.conf` and `<backend>-<doctype>.conf` from location 4.
+- Filter conf files from location 4.
+- `<docfile>.conf` and `<docfile>-<backend>.conf` from location 4.
+- Configuration files from location 5.
+
+Where:
+
+- `<backend>` and `<doctype>` are values specified by the asciidoc(1)
+  `-b` (`--backend`) and `-d` (`--doctype`) command-line options.
+- `<infile>` is the path name of the AsciiDoc input file without the
+  file name extension.
+- `<lang>` is a two letter country code set by the the AsciiDoc 'lang'
+  attribute.
+
+NOTE
+=====================================================================
+The backend and language global configuration files are loaded *after*
+the header has been parsed.  This means that you can set most
+attributes in the document header. Here's an example header:
+
+  Life's Mysteries
+  ================
+  :author: Hu Nose
+  :doctype: book
+  :toc:
+  :icons:
+  :data-uri:
+  :lang: en
+  :encoding: iso-8859-1
+
+Attributes set in the document header take precedence over
+configuration file attributes.
+
+=====================================================================
+
+TIP: Use the asciidoc(1) `-v` (`--verbose`) command-line option to see
+which configuration files are loaded and the order in which they are
+loaded.
+
+
+Document Attributes
+-------------------
+A document attribute is comprised of a 'name' and a textual 'value'
+and is used for textual substitution in AsciiDoc documents and
+configuration files. An attribute reference (an attribute name
+enclosed in braces) is replaced by the corresponding attribute
+value. Attribute names are case insensitive and can only contain
+alphanumeric, dash and underscore characters.
+
+There are four sources of document attributes (from highest to lowest
+precedence):
+
+- Command-line attributes.
+- AttributeEntry, AttributeList, Macro and BlockId elements.
+- Configuration file `attributes` sections.
+- Intrinsic attributes.
+
+Within each of these divisions the last processed entry takes
+precedence.
+
+NOTE: If an attribute is not defined then the line containing the
+attribute reference is dropped. This property is used extensively in
+AsciiDoc configuration files to facilitate conditional markup
+generation.
+
+
+X18
+Attribute Entries
+-----------------
+The `AttributeEntry` block element allows document attributes to be
+assigned within an AsciiDoc document. Attribute entries are added to
+the global document attributes dictionary. The attribute name/value
+syntax is a single line like:
+
+  :<name>: <value>
+
+For example:
+
+  :Author Initials: JB
+
+This will set an attribute reference `{authorinitials}` to the value
+'JB' in the current document.
+
+To delete (undefine) an attribute use the following syntax:
+
+  :<name>!:
+
+.AttributeEntry behavior
+- The attribute entry line begins with colon -- no white space allowed
+  in left margin.
+- AsciiDoc converts the `<name>` to a legal attribute name (lower
+  case, alphanumeric, dash and underscore characters only -- all other
+  characters deleted). This allows more human friendly text to be
+  used.
+- Leading and trailing white space is stripped from the `<value>`.
+- Lines ending in a space followed by a plus character are continued
+  to the next line, for example:
+
+  :description: AsciiDoc is a text document format for writing notes, +
+                documentation, articles, books, slideshows, web pages +
+                and man pages.
+
+- If the `<value>` is blank then the corresponding attribute value is
+  set to an empty string.
+- Attribute references contained in the entry `<value>` will be
+  expanded.
+- By default AttributeEntry values are substituted for
+  `specialcharacters` and `attributes` (see above), if you want to
+  change or disable AttributeEntry substitution use the <<X77,\pass:
+  inline macro>> syntax.
+- Attribute entries in the document Header are available for header
+  markup template substitution.
+- Attribute elements override configuration file and intrinsic
+  attributes but do not override command-line attributes.
+
+Here are some more attribute entry examples:

+
+Setting configuration entries
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+A variant of the Attribute Entry syntax allows configuration file
+section entries and markup template sections to be set from within an
+AsciiDoc document:
+
+  :<section_name>.<entry_name>: <entry_value>
+
+Where `<section_name>` is the configuration section name,
+`<entry_name>` is the name of the entry and `<entry_value>` is the
+optional entry value. This example sets the default labeled list
+style to 'horizontal':
+
+  :listdef-labeled.style: horizontal
+
+It is exactly equivalent to a configuration file containing:
+
+  listdef-labeled
+  style=horizontal
+
+- If the `<entry_name>` is omitted then the entire section is
+  substituted with the `<entry_value>`. This feature should only be
+  used to set markup template sections. The following example sets the
+  'xref2' inline macro markup template:
+
+  :xref2-inlinemacro.: <a href="#{1}">{2?{2}}</a>
+
+- No substitution is performed on configuration file attribute entries
+  and they cannot be undefined.
+- This feature can only be used in attribute entries -- configuration
+  attributes cannot be set using the asciidoc(1) command `--attribute`
+  option.
+
+X62
+.Attribute entries promote clarity and eliminate repetition
+*********************************************************************
+URLs and file names in AsciiDoc macros are often quite long -- they
+break paragraph flow and readability suffers.  The problem is
+compounded by redundancy if the same name is used repeatedly.
+Attribute entries can be used to make your documents easier to read
+and write, here are some examples:
+
+  :1:         http://freshmeat.sourceforge.net/projects/asciidoc/
+  :homepage:  https://asciidoc.orgAsciiDoc home page
+  :new:       image:./images/smallnew.png
+  :footnote1: footnote:A meaningless latin term
+
+  Using previously defined attributes: See the {1}Freshmeat summary
+  or the {homepage} for something new {new}. Lorem ispum {footnote1}.
+
+.Note
+- The attribute entry definition must precede it's usage.
+- You are not limited to URLs or file names, entire macro calls or
+  arbitrary lines of text can be abbreviated.
+- Shared attributes entries could be grouped into a separate file and
+  <<X63,included>> in multiple documents.
+*********************************************************************
+
+
+X21
+Attribute Lists
+---------------
+- An attribute list is a comma separated list of attribute values.
+- The entire list is enclosed in square brackets.
+- Attribute lists are used to pass parameters to macros, blocks (using
+  the <<X79,AttributeList element>>) and inline quotes.
+
+The list consists of zero or more positional attribute values followed
+by zero or more named attribute values.  Here are three examples: a
+single unquoted positional attribute; three unquoted positional
+attribute values; one positional attribute followed by two named
+attributes; the unquoted attribute value in the final example contains
+comma (`&#44;`) and double-quote (`&#34;`) character entities:
+
+  Hello
+  quote, Bertrand Russell, The World of Mathematics (1956)
+  "22 times", backcolor="#0e0e0e", options="noborders,wide"
+  A footnote&#44; &#34;with an image&#34; image:smallnew.png
+
+.Attribute list behavior
+- If one or more attribute values contains a comma the all string
+  values must be quoted (enclosed in double quotation mark
+  characters).
+- If the list contains any named or quoted attributes then all string
+  attribute values must be quoted.
+- To include a double quotation mark (") character in a quoted
+  attribute value the the quotation mark must be escaped with a
+  backslash.
+- List attributes take precedence over existing attributes.
+- List attributes can only be referenced in configuration file markup
+  templates and tags, they are not available elsewhere in the
+  document.
+- Setting a named attribute to `None` undefines the attribute.
+- Positional attributes are referred to as `{1}`,`{2}`,`{3}`,...
+- Attribute `{0}` refers to the entire list (excluding the enclosing
+  square brackets).
+- Named attribute names cannot contain dash characters.
+
+X75
+Options attribute
+~~~~~~~~~~~~~~~~~
+If the attribute list contains an attribute named `options` it is
+processed as a comma separated list of option names:
+
+- Each name generates an attribute named like `<option>-option` (where
+  `<option>` is the option name) with an empty string value.  For
+  example `options="opt1,opt2,opt3"` is equivalent to setting the
+  following three attributes
+  `opt1-option="",opt2-option="",opt2-option=""`.
+- If you define a an option attribute globally (for example with an
+  <<X18,attribute entry>>) then it will apply to all elements in the
+  document.
+- AsciiDoc implements a number of predefined options which are listed
+  in the <<X74,Attribute Options appendix>>.
+
+Macro Attribute lists
+~~~~~~~~~~~~~~~~~~~~~
+Macros calls are suffixed with an attribute list. The list may be
+empty but it cannot be omitted. List entries are used to pass
+attribute values to macro markup templates.
+
+
+Attribute References
+--------------------
+An attribute reference is an attribute name (possibly followed by an
+additional parameters) enclosed in curly braces.  When an attribute
+reference is encountered it is evaluated and replaced by its
+corresponding text value.  If the attribute is undefined the line
+containing the attribute is dropped.
+
+There are three types of attribute reference: 'Simple', 'Conditional'
+and 'System'.
+
+.Attribute reference evaluation
+- You can suppress attribute reference expansion by placing a
+  backslash character immediately in front of the opening brace
+  character.
+- By default attribute references are not expanded in
+  'LiteralParagraphs', 'ListingBlocks' or 'LiteralBlocks'.
+- Attribute substitution proceeds line by line in reverse line order.
+- Attribute reference evaluation is performed in the following order:
+  'Simple' then 'Conditional' and finally 'System'.
+
+Simple Attributes References
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Simple attribute references take the form `{<name>}`. If the
+attribute name is defined its text value is substituted otherwise the
+line containing the reference is dropped from the output.
+
+Conditional Attribute References
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Additional parameters are used in conjunction with attribute names to
+calculate a substitution value. Conditional attribute references take
+the following forms:
+
+`{<names>=<value>}`::
+        `<value>` is substituted if the attribute `<names>` is
+        undefined otherwise its value is substituted. `<value>` can
+        contain simple attribute references.
+
+`{<names>?<value>}`::
+        `<value>` is substituted if the attribute `<names>` is defined
+        otherwise an empty string is substituted.  `<value>` can
+        contain simple attribute references.
+
+`{<names>!<value>}`::
+        `<value>` is substituted if the attribute `<names>` is
+        undefined otherwise an empty string is substituted.  `<value>`
+        can contain simple attribute references.
+
+`{<names>#<value>}`::
+        `<value>` is substituted if the attribute `<names>` is defined
+        otherwise the undefined attribute entry causes the containing
+        line to be dropped.  `<value>` can contain simple attribute
+        references.
+
+`{<names>%<value>}`::
+        `<value>` is substituted if the attribute `<names>` is not
+        defined otherwise the containing line is dropped.  `<value>`
+        can contain simple attribute references.
+
+`{<names>@<regexp>:<value1>:<value2>}`::
+        `<value1>` is substituted if the value of attribute `<names>`
+        matches the regular expression `<regexp>` otherwise `<value2>`
+        is substituted. If attribute `<names>` is not defined the
+        containing line is dropped. If `<value2>` is omitted an empty
+        string is assumed. The values and the regular expression can
+        contain simple attribute references.  To embed colons in the
+        values or the regular expression escape them with backslashes.
+
+`{<names>$<regexp>:<value1>:<value2>}`::
+        Same behavior as the previous ternary attribute except for
+        the following cases:
+
+        `{<names>$<regexp>:<value>}`;;
+                Substitutes `<value>` if `<names>` matches `<regexp>`
+                otherwise the result is undefined and the containing
+                line is dropped.
+
+        `{<names>$<regexp>::<value>}`;;
+                Substitutes `<value>` if `<names>` does not match
+                `<regexp>` otherwise the result is undefined and the
+                containing line is dropped.
+
+The attribute `<names>` parameter normally consists of a single
+attribute name but it can be any one of the following:
+
+- A single attribute name which evaluates to the attributes value.
+- Multiple ',' separated attribute names which evaluates to an empty
+  string if one or more of the attributes is defined, otherwise it's
+  value is undefined.
+- Multiple '+' separated attribute names which evaluates to an empty
+  string if all of the attributes are defined, otherwise it's value is
+  undefined.
+
+Conditional attributes with single attribute names are evaluated first
+so they can be used inside the multi-attribute conditional `<value>`.
+
+Conditional attribute examples
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Conditional attributes are mainly used in AsciiDoc configuration
+files -- see the distribution `.conf` files for examples.
+
+Attribute equality test::
+  If `{backend}` is 'docbook45' or 'xhtml11' the example evaluates to
+  ``DocBook 4.5 or XHTML 1.1 backend'' otherwise it evaluates to
+  ``some other backend'':
+
+  {backend@docbook45|xhtml11:DocBook 4.5 or XHTML 1.1 backend:some other backend}
+
+Attribute value map::
+  This example maps the `frame` attribute values `topbot`, `all`,
+  `none`, `sides` to `hsides`, `border`, `void`, `vsides`:
+
+  {frame@topbot:hsides}{frame@all:border}{frame@none:void}{frame@sides:vsides}
+
+
+X24
+System Attribute References
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+System attribute references generate the attribute text value by
+executing a predefined action that is parametrized by one or more
+arguments. The syntax is `{<action>:<arguments>}`.
+
+`{counter:<attrname>:<seed>}`::
+        Increments the document attribute (if the attribute is
+        undefined it is set to `1`). Returns the new attribute value.
+
+        - Counters generate global (document wide) attributes.
+        - The optional `<seed>` specifies the counter's initial value;
+          it can be a number or a single letter; defaults to '1'.
+        - `<seed>` can contain simple and conditional attribute
+          references.
+        - The 'counter' system attribute will not be executed if the
+          containing line is dropped by the prior evaluation of an
+          undefined attribute.
+
+`{counter2:<attrname>:<seed>}`::
+        Same as `counter` except the it always returns a blank string.
+
+`{eval:<expression>}`::
+        Substitutes the result of the Python `<expression>`.
+
+        - If `<expression>` evaluates to `None` or `False` the
+          reference is deemed undefined and the line containing the
+          reference is dropped from the output.
+        - If the expression evaluates to `True` the attribute
+          evaluates to an empty string.
+        - `<expression>` can contain simple and conditional attribute
+          references.
+        - The 'eval' system attribute can be nested inside other
+          system attributes.
+
+`{eval3:<command>}`::
+        Passthrough version of `{eval:<expression>}` -- the generated
+        output is written directly to the output without any further
+        substitutions.
+
+`{include:<filename>}`::
+        Substitutes contents of the file named `<filename>`.
+
+        - The included file is read at the time of attribute
+          substitution.
+        - If the file does not exist a warning is emitted and the line
+          containing the reference is dropped from the output file.
+        - Tabs are expanded based on the current 'tabsize' attribute
+          value.
+
+`{set:<attrname>!:<value>}`::
+        Sets or unsets document attribute. Normally only used in
+        configuration file markup templates (use
+        <<X18,AttributeEntries>> in AsciiDoc documents).
+
+        - If the attribute name is followed by an exclamation mark
+          the attribute becomes undefined.
+        - If `<value>` is omitted the attribute is set to a blank
+          string.
+        - `<value>` can contain simple and conditional attribute
+          references.
+        - Returns a blank string unless the attribute is undefined in
+          which case the return value is undefined and the enclosing
+          line will be dropped.
+
+`{set2:<attrname>!:<value>}`::
+        Same as `set` except that the attribute scope is local to the
+        template.
+
+`{sys:<command>}`::
+        Substitutes the stdout generated by the execution of the shell
+        `<command>`.
+
+`{sys2:<command>}`::
+        Substitutes the stdout and stderr generated by the execution
+        of the shell `<command>`.
+
+`{sys3:<command>}`::
+        Passthrough version of `{sys:<command>}` -- the generated
+        output is written directly to the output without any further
+        substitutions.
+
+`{template:<template>}`::
+        Substitutes the contents of the configuration file section
+        named `<template>`. Attribute references contained in the
+        template are substituted.
+
+.System reference behavior
+- System attribute arguments can contain non-system attribute
+  references.
+- Closing brace characters inside system attribute arguments must be
+  escaped with a backslash.

+
+NOTE
+======
+1. Intrinsic attributes are global so avoid defining custom attributes
+   with the same names.
+2. `{outfile}`, `{outdir}`, `{infile}`, `{indir}` attributes are
+   effectively read-only (you can set them but it won't affect the
+   input or output file paths).
+3.  See also the <<X88,Backend Attributes>> section for attributes
+    that relate to AsciiDoc XHTML file generation.
+4. The entries that translate to blank strings are designed to be used
+   for conditional text inclusion. You can also use the `ifdef`,
+   `ifndef` and `endif` System macros for conditional inclusion.
+   footnote:Conditional inclusion using `ifdef` and `ifndef` macros
+   differs from attribute conditional inclusion in that the former
+   occurs when the file is read while the latter occurs when the
+   contents are written.
+5. `{docfile}` and `{docdir}` refer to root document specified on the
+   asciidoc(1) command-line; `{infile}` and `{indir}` refer to the
+   current input file which may be the root document or an included
+   file. When the input is being read from the standard input
+   (`stdin`) these attributes are undefined.
+6. If the input file is the standard input and the output file is not
+   the standard output then `{docname}` is the output file name sans
+   file extension.
+7. See
+   https://en.wikipedia.org/wiki/Quotation_mark#Summary_tablenon-English
+   usage of quotation marks.
+8. The `{blockname}` attribute identifies the style of the current
+   block. It applies to delimited blocks, lists and tables. Here is a
+   list of `{blockname}` values (does not include filters or custom
+   block and style names):
+
+   delimited blocks:: comment, sidebar, open, pass, literal, verse,
+   listing, quote, example, note, tip, important, caution, warning,
+   abstract, partintro
+
+   lists:: arabic, loweralpha, upperalpha, lowerroman, upperroman,
+   labeled, labeled3, labeled4, qanda, horizontal, bibliography,
+   glossary
+
+   tables:: table
+9. If the `SOURCE_DATE_EPOCH` environment variable is set to a UNIX
+   timestamp, then the `{docdate}`, `{doctime}`, `{localdate}`, and
+   `{localtime}` attributes are computed in the UTC time zone, with any
+   timestamps newer than `SOURCE_DATE_EPOCH` replaced by
+   `SOURCE_DATE_EPOCH`. (This helps software using AsciiDoc to build
+   reproducibly.)

+X73
+Block Element Definitions
+-------------------------
+The syntax and behavior of Paragraph, DelimitedBlock, List and Table
+block elements is determined by block definitions contained in
+<<X7,AsciiDoc configuration file>> sections.
+
+Each definition consists of a section title followed by one or more
+section entries. Each entry defines a block parameter controlling some
+aspect of the block's behavior. Here's an example:
+
+---------------------------------------------------------------------
+blockdef-listing
+delimiter=^-{4,}$
+template=listingblock
+presubs=specialcharacters,callouts
+---------------------------------------------------------------------
+
+Configuration file block definition sections are processed
+incrementally after each configuration file is loaded. Block
+definition section entries are merged into the block definition, this
+allows block parameters to be overridden and extended by later
+<<X27,loading configuration files>>.
+
+AsciiDoc Paragraph, DelimitedBlock, List and Table block elements
+share a common subset of configuration file parameters:
+
+delimiter::
+  A Python regular expression that matches the first line of a block
+  element -- in the case of DelimitedBlocks and Tables it also matches
+  the last line.
+
+template::
+  The name of the configuration file markup template section that will
+  envelope the block contents. The pipe ('|') character is substituted
+  for the block contents. List elements use a set of (list specific)
+  tag parameters instead of a single template. The template name can
+  contain attribute references allowing dynamic template selection a
+  the time of template substitution.
+
+options::
+  A comma delimited list of element specific option names. In addition
+  to being used internally, options are available during markup tag
+  and template substitution as attributes with an empty string value
+  named like `<option>-option` (where `<option>` is the option name).
+  See <<X74,attribute options>> for a complete list of available
+  options.
+
+subs, presubs, postsubs::
+  * 'presubs' and 'postsubs' are lists of comma separated substitutions that are
+    performed on the block contents. 'presubs' is applied first,
+    'postsubs' (if specified) second.
+
+  * 'subs' is an alias for 'presubs'.
+
+  * If a 'filter' is allowed (Paragraphs, DelimitedBlocks and Tables)
+    and has been specified then 'presubs' and 'postsubs' substitutions
+    are performed before and after the filter is run respectively.
+
+  * Allowed values: 'specialcharacters', 'quotes', 'specialwords',
+    'replacements', 'macros', 'attributes', 'callouts'.
+
+  * X102The following composite values are also allowed:
+
+    'none';;
+        No substitutions.
+    'normal';;
+        The following substitutions in the following order:
+        'specialcharacters', 'quotes', 'attributes', 'specialwords',
+        'replacements', 'macros', 'replacements2'.
+    'verbatim';;
+        The following substitutions in the following order:
+        'specialcharacters' and 'callouts'.
+
+  * 'normal' and 'verbatim' substitutions can be redefined by with
+    `subsnormal` and `subsverbatim` entries in a configuration file
+    `miscellaneous` section.
+
+  * The substitutions are processed in the order in which they are
+    listed and can appear more than once.
+
+filter::
+  This optional entry specifies an executable shell command for
+  processing block content (Paragraphs, DelimitedBlocks and Tables).
+  The filter command can contain attribute references.
+
+posattrs::
+  Optional comma separated list of positional attribute names. This
+  list maps positional attributes (in the block's <<X21,attribute
+  list>>) to named block attributes. The following example, from the
+  QuoteBlock definition, maps the first and section positional
+  attributes:
+
+  posattrs=attribution,citetitle
+
+style::
+  This optional parameter specifies the default style name.
+
+
+<stylename>-style::
+  Optional style definition (see <<X23,Styles>> below).
+
+The following block parameters behave like document attributes and can
+be set in block attribute lists and style definitions: 'template',
+'options', 'subs', 'presubs', 'postsubs', 'filter'.
+
+X23
+Styles
+~~~~~~
+A style is a set of block parameter bundled as a single named
+parameter. The following example defines a style named 'verbatim':
+
+  verbatim-style=template="literalblock",subs="verbatim"
+
+If a block's <<X21,attribute list>> contains a 'style' attribute then
+the corresponding style parameters are be merged into the default
+block definition parameters.
+
+- All style parameter names must be suffixed with `-style` and the
+  style parameter value is in the form of a list of <<X21,named
+  attributes>>.
+- The 'template' style parameter is mandatory, other parameters can be
+  omitted in which case they inherit their values from the default
+  block definition parameters.
+- Multi-item style parameters ('subs','presubs','postsubs','posattrs')
+  must be specified using Python tuple syntax (rather than a simple
+  list of values as they in separate entries) e.g.
+  `postsubs=("callouts",)` not `postsubs="callouts"`.
+
+Paragraphs
+~~~~~~~~~~
+Paragraph translation is controlled by `paradef-*` configuration
+file section entries. Users can define new types of paragraphs and
+modify the behavior of existing types by editing AsciiDoc
+configuration files.
+
+Here is the shipped Default paragraph definition:
+
+--------------------------------------------------------------------
+paradef-default
+delimiter=(?P<text>\S.*)
+template=paragraph
+--------------------------------------------------------------------
+
+The normal paragraph definition has a couple of special properties:
+
+1. It must exist and be defined in a configuration file section named
+   `paradef-default`.
+2. Irrespective of its position in the configuration files default
+   paragraph document matches are attempted only after trying all
+   other paragraph types.
+
+Paragraph specific block parameter notes:
+
+delimiter::
+  This regular expression must contain the named group 'text' which
+  matches the text on the first line.  Paragraphs are terminated by a
+  blank line, the end of file, or the start of a DelimitedBlock.
+
+options::
+  The 'listelement' option specifies that paragraphs of this type will
+  automatically be considered part of immediately preceding list
+  items.  The 'skip' option causes the paragraph to be treated as a
+  comment (see <<X26,CommentBlocks>>).
+
+.Paragraph processing proceeds as follows:
+1. The paragraph text is aligned to the left margin.
+2. Optional 'presubs' inline substitutions are performed on the
+   paragraph text.
+3. If a filter command is specified it is executed and the paragraph
+   text piped to its standard input; the filter output replaces the
+   paragraph text.
+4. Optional 'postsubs' inline substitutions are performed on the
+   paragraph text.
+5. The paragraph text is enveloped by the paragraph's markup template
+   and written to the output file.
+
+Delimited Blocks
+~~~~~~~~~~~~~~~~
+DelimitedBlock 'options' values are:
+
+sectionbody::
+    The block contents are processed as a SectionBody.
+
+skip::
+    The block is treated as a comment (see <<X26,CommentBlocks>>).
+    Preceding <<X21,attribute lists>> and <<X42,block titles>> are not
+    consumed.
+
+'presubs', 'postsubs' and 'filter' entries are ignored when
+'sectionbody' or 'skip' options are set.
+
+DelimitedBlock processing proceeds as follows:
+
+1. Optional 'presubs' substitutions are performed on the block
+   contents.
+2. If a filter is specified it is executed and the block's contents
+   piped to its standard input. The filter output replaces the block
+   contents.
+3. Optional 'postsubs' substitutions are performed on the block
+   contents.
+4. The block contents is enveloped by the block's markup template and
+   written to the output file.
+
+TIP: Attribute expansion is performed on the block filter command
+before it is executed, this is useful for passing arguments to the
+filter.
+
+Lists
+~~~~~
+List behavior and syntax is determined by `listdef-*` configuration
+file sections. The user can change existing list behavior and add new
+list types by editing configuration files.
+
+List specific block definition notes:
+
+type::
+  This is either 'bulleted','numbered','labeled' or 'callout'.
+
+delimiter::
+  A Python regular expression that matches the first line of a
+  list element entry. This expression can contain the named groups
+  'text' (bulleted groups), 'index' and 'text' (numbered lists),
+  'label' and 'text' (labeled lists).
+
+tags::
+  The `<name>` of the `listtags-<name>` configuration file section
+  containing list markup tag definitions.  The tag entries ('list',
+  'entry', 'label', 'term', 'text') map the AsciiDoc list structure to
+  backend markup; see the 'listtags' sections in the AsciiDoc
+  distributed backend `.conf` configuration files for examples.
+
+Tables
+~~~~~~
+Table behavior and syntax is determined by `tabledef-*` and
+`tabletags-*` configuration file sections. The user can change
+existing table behavior and add new table types by editing
+configuration files.  The following `tabledef-*` section entries
+generate table output markup elements:
+
+colspec::
+  The table 'colspec' tag definition.
+
+headrow, footrow, bodyrow::
+  Table header, footer and body row tag definitions. 'headrow' and
+  'footrow' table definition entries default to 'bodyrow' if
+  they are undefined.
+
+headdata, footdata, bodydata::
+  Table header, footer and body data tag definitions. 'headdata' and
+  'footdata' table definition entries default to 'bodydata' if they
+  are undefined.
+
+paragraph::
+  If the 'paragraph' tag is specified then blank lines in the cell
+  data are treated as paragraph delimiters and marked up using this
+  tag.
+
+X4
+Table behavior is also influenced by the following `miscellaneous`
+configuration file entries:
+
+pagewidth::
+  This integer value is the printable width of the output media. See
+  <<X69,table attributes>>.
+
+pageunits::
+  The units of width in output markup width attribute values.
+
+.Table definition behavior
+- The output markup generation is specifically designed to work with
+  the HTML and CALS (DocBook) table models, but should be adaptable to
+  most XML table schema.
+- Table definitions can be ``mixed in'' from multiple cascading
+  configuration files.
+- New table definitions inherit the default table and table tags
+  definitions (`tabledef-default` and `tabletags-default`) so you
+  only need to override those conf file entries that require
+  modification.
+
+
+X59
+Filters
+-------
+AsciiDoc filters allow external commands to process AsciiDoc
+'Paragraphs', 'DelimitedBlocks' and 'Table' content. Filters are
+primarily an extension mechanism for generating specialized outputs.
+Filters are implemented using external commands which are specified in
+configuration file definitions.
+
+There's nothing special about the filters, they're just standard UNIX
+filters: they read text from the standard input, process it, and write
+to the standard output.
+
+The asciidoc(1) command `--filter` option can be used to install and
+remove filters. The same option is used to unconditionally load a
+filter.
+
+Attribute substitution is performed on the filter command prior to
+execution -- attributes can be used to pass parameters from the
+AsciiDoc source document to the filter.
+
+WARNING: Filters sometimes included executable code. Before installing
+a filter you should verify that it is from a trusted source.
+
+Filter Search Paths
+~~~~~~~~~~~~~~~~~~~
+If the filter command does not specify a directory path then
+asciidoc(1) recursively searches for the executable filter command:
+
+- First it looks in the user's `$HOME/.asciidoc/filters` directory.
+- Next the global filters directory (usually `/etc/asciidoc/filters`
+  or `/usr/local/etc/asciidoc`) directory is searched.
+- Then it looks in the asciidoc(1) `./filters` directory.
+- Finally it relies on the executing shell to search the environment
+  search path (`$PATH`).
+
+Standard practice is to install each filter in it's own sub-directory
+with the same name as the filter's style definition. For example the
+music filter's style name is 'music' so it's configuration and filter
+files are stored in the `filters/music` directory.
+
+Filter Configuration Files
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+Filters are normally accompanied by a configuration file containing a
+Paragraph or DelimitedBlock definition along with corresponding markup
+templates.
+
+While it is possible to create new 'Paragraph' or 'DelimitedBlock'
+definitions the preferred way to implement a filter is to add a
+<<X23,style>> to the existing Paragraph and ListingBlock definitions
+(all filters shipped with AsciiDoc use this technique). The filter is
+applied to the paragraph or delimited block by preceding it with an
+attribute list: the first positional attribute is the style name,
+remaining attributes are normally filter specific parameters.
+
+asciidoc(1) auto-loads all `.conf` files found in the filter search
+paths unless the container directory also contains a file named
+`__noautoload__` (see previous section). The `__noautoload__` feature
+is used for filters that will be loaded manually using the `--filter`
+option.
+
+X56
+Example Filter
+~~~~~~~~~~~~~~
+AsciiDoc comes with a toy filter for highlighting source code keywords
+and comments.  See also the `./filters/code/code-filter-readme.txt`
+file.
+
+NOTE: The purpose of this toy filter is to demonstrate how to write a
+filter -- it's much to simplistic to be passed off as a code syntax
+highlighter.  If you want a full featured multi-language highlighter
+use the {website}source-highlight-filter.htmlsource code highlighter
+filter.
+
+Built-in filters
+~~~~~~~~~~~~~~~~
+The AsciiDoc distribution includes 'source', 'music', 'latex' and
+'graphviz' filters, details are on the
+{website}index.html#_filtersAsciiDoc website.

+Filter plugins
+~~~~~~~~~~~~~~
+Filter <<X101,plugins>> are a mechanism for distributing AsciiDoc
+filters.  A filter plugin is a Zip file containing the files that
+constitute a filter.  The asciidoc(1) `--filter` option is used to
+load and manage filer <<X101,plugins>>.
+
+- Filter plugins <<X27,take precedence>> over built-in filters with
+  the same name.
+- By default filter plugins are installed in
+  `$HOME/.asciidoc/filters/<filter>` where `<filter>` is the filter
+  name.
+
+
+X101
+Plugins
+-------
+The AsciiDoc plugin architecture is an extension mechanism that allows
+additional <<X100,backends>>, <<X58,filters>> and <<X99,themes>> to be
+added to AsciiDoc.
+
+- A plugin is a Zip file containing an AsciiDoc backend, filter or
+  theme (configuration files, stylesheets, scripts, images).
+- The asciidoc(1) `--backend`, `--filter` and `--theme` command-line
+  options are used to load and manage plugins. Each of these options
+  responds to the plugin management 'install', 'list', 'remove' and
+  'build' commands.
+- The plugin management command names are reserved and cannot be used
+  for filter, backend or theme names.
+- The plugin Zip file name always begins with the backend, filter or
+  theme name.
+
+Plugin commands and conventions are documented in the asciidoc(1) man
+page.  You can find lists of plugins on the
+{website}plugins.htmlAsciiDoc website.

+  $ asciidoc --help
+
+To print a help topic specify the topic name as a command argument.
+Help topic names can be shortened so long as they are not ambiguous.
+Examples:
+
+  $ asciidoc --help manpage
+  $ asciidoc -h m              # Short version of previous example.
+  $ asciidoc --help syntax
+  $ asciidoc -h s              # Short version of previous example.
+
+Customizing Help
+~~~~~~~~~~~~~~~~
+To change, delete or add your own help topics edit a help
+configuration file.  The help file name `help-<lang>.conf` is based on
+the setting of the `lang` attribute, it defaults to `help.conf`
+(English).  The <<X27,help file location>> will depend on whether you
+want the topics to apply to all users or just the current user.
+
+The help topic files have the same named section format as other
+<<X7,configuration files>>. The `help.conf` files are stored in the
+same locations and loaded in the same order as other configuration
+files.
+
+When the `--help` command-line option is specified AsciiDoc loads the
+appropriate help files and then prints the contents of the section
+whose name matches the help topic name.  If a topic name is not
+specified `default` is used. You don't need to specify the whole help
+topic name on the command-line, just enough letters to ensure it's not
+ambiguous. If a matching help file section is not found a list of
+available topics is printed.
+
+
+Tips and Tricks
+---------------
+
+Know Your Editor
+~~~~~~~~~~~~~~~~
+Writing AsciiDoc documents will be a whole lot more pleasant if you
+know your favorite text editor. Learn how to indent and reformat text
+blocks, paragraphs, lists and sentences. <<X20,Tips for 'vim' users>>
+follow.
+
+X20
+Vim Commands for Formatting AsciiDoc
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Text Wrap Paragraphs
+^^^^^^^^^^^^^^^^^^^^
+Use the vim `:gq` command to reformat paragraphs. Setting the
+'textwidth' sets the right text wrap margin; for example:
+
+  :set textwidth=70
+
+To reformat a paragraph:
+
+1. Position the cursor at the start of the paragraph.
+2. Type `gq}`.
+
+Execute `:help gq` command to read about the vim gq command.
+
+TIP
+=====================================================================
+- Assign the `gq}` command to the Q key with the `nnoremap Q gq}`
+  command or put it in your `~/.vimrc` file to so it's always
+  available (see the <<X61, Example `~/.vimrc` file>>).
+- Put `set` commands in your `~/.vimrc` file so you don't have to
+  enter them manually.
+- The Vim website (https://www.vim.org/) has a wealth of resources,
+  including scripts for automated spell checking and ASCII Art
+  drawing.
+=====================================================================
+
+Format Lists
+^^^^^^^^^^^^
+The `gq` command can also be used to format bulleted, numbered and
+callout lists. First you need to set the `comments`, `formatoptions`
+and `formatlistpat` (see the <<X61, Example `~/.vimrc` file>>).
+
+Now you can format simple lists that use dash, asterisk, period and
+plus bullets along with numbered ordered lists:
+
+1. Position the cursor at the start of the list.
+2. Type `gq}`.
+
+Indent Paragraphs
+^^^^^^^^^^^^^^^^^
+Indent whole paragraphs by indenting the fist line with the desired
+indent and then executing the `gq}` command.
+
+X61
+Example `~/.vimrc` File
+^^^^^^^^^^^^^^^^^^^^^^^

+---------------------------------------------------------------------
+
+Troubleshooting
+~~~~~~~~~~~~~~~
+AsciiDoc diagnostic features are detailed in the <<X82,Diagnostics
+appendix>>.
+
+Gotchas
+~~~~~~~
+Incorrect character encoding::
+    If you get an error message like `'UTF-8' codec can't decode ...`
+    then you source file contains invalid UTF-8 characters -- set the
+    AsciiDoc <<X54,encoding attribute>> for the correct character set
+    (typically ISO-8859-1 (Latin-1) for European languages).
+
+Invalid output::
+    AsciiDoc attempts to validate the input AsciiDoc source but makes
+    no attempt to validate the output markup, it leaves that to
+    external tools such as `xmllint(1)` (integrated into `a2x(1)`).
+    Backend validation cannot be hardcoded into AsciiDoc because
+    backends are dynamically configured. The following example
+    generates valid HTML but invalid DocBook (the DocBook `literal`
+    element cannot contain an `emphasis` element):
+
+    +monospaced text with an _emphasized_ word+
+
+Misinterpreted text formatting::
+    You can suppress markup expansion by placing a backslash character
+    immediately in front of the element. The following example
+    suppresses inline monospaced formatting:
+
+    \+1 for C++.
+
+Overlapping text formatting::
+    Overlapping text formatting will generate illegal overlapping
+    markup tags which will result in downstream XML parsing errors.
+    Here's an example:
+
+    Some *strong markup _that overlaps* emphasized markup_.
+
+Ambiguous underlines::
+    A DelimitedBlock can immediately follow a paragraph without an
+    intervening blank line, but be careful, a single line paragraph
+    underline may be misinterpreted as a section title underline
+    resulting in a ``closing block delimiter expected'' error.
+
+Ambiguous ordered list items::
+    Lines beginning with numbers at the end of sentences will be
+    interpreted as ordered list items.  The following example
+    (incorrectly) begins a new list with item number 1999:
+
+    He was last sighted in
+    1999. Since then things have moved on.
++
+The 'list item out of sequence' warning makes it unlikely that this
+problem will go unnoticed.
+
+Special characters in attribute values::
+    Special character substitution precedes attribute substitution so
+    if attribute values contain special characters you may, depending
+    on the substitution context, need to escape the special characters
+    yourself. For example:
+
+    $ asciidoc -a 'orgname=Bill &amp; Ben Inc.' mydoc.txt
+
+Attribute lists::
+    If any named attribute entries are present then all string
+    attribute values must be quoted.  For example:
+
+    "Desktop screenshot",width=32
+
+X90
+Combining separate documents
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You have a number of stand-alone AsciiDoc documents that you want to
+process as a single document. Simply processing them with a series of
+`include` macros won't work because the documents contain (level 0)
+document titles.  The solution is to create a top level wrapper
+document and use the `leveloffset` attribute to push them all down one
+level. For example:
+
+listing
+.....................................................................
+Combined Document Title
+=======================
+
+// Push titles down one level.
+:leveloffset: 1
+
+\include::document1.txt
+
+// Return to normal title levels.
+:leveloffset: 0
+
+A Top Level Section
+-------------------
+Lorum ipsum.
+
+// Push titles down one level.
+:leveloffset: 1
+
+\include::document2.txt
+
+\include::document3.txt
+.....................................................................
+
+The document titles in the included documents will now be processed as
+level 1 section titles, level 1 sections as level 2 sections and so
+on.
+
+- Put a blank line between the `include` macro lines to ensure the
+  title of the included document is not seen as part of the last
+  paragraph of the previous document.
+- You won't want non-title document header lines (for example, Author
+  and Revision lines) in the included files -- conditionally exclude
+  them if they are necessary for stand-alone processing.
+
+Processing document sections separately
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You have divided your AsciiDoc document into separate files (one per
+top level section) which are combined and processed with the following
+top level document:
+
+---------------------------------------------------------------------
+Combined Document Title
+=======================
+Joe Bloggs
+v1.0, 12-Aug-03
+
+\include::section1.txt
+
+\include::section2.txt
+
+\include::section3.txt
+---------------------------------------------------------------------
+
+You also want to process the section files as separate documents.
+This is easy because asciidoc(1) will quite happily process
+`section1.txt`, `section2.txt` and `section3.txt` separately -- the
+resulting output documents contain the section but have no document
+title.
+
+Processing document snippets
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Use the `-s` (`--no-header-footer`) command-line option to suppress
+header and footer output, this is useful if the processed output is to
+be included in another file. For example:
+
+  $ asciidoc -sb docbook section1.txt
+
+asciidoc(1) can be used as a filter, so you can pipe chunks of text
+through it. For example:
+
+  $ echo 'Hello *World!*' | asciidoc -s -
+  <div class="paragraph"><p>Hello <strong>World!</strong></p></div>
+
+Badges in HTML page footers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+See the `footer` section in the AsciiDoc distribution `xhtml11.conf`
+configuration file.
+
+Pretty printing AsciiDoc output
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If the indentation and layout of the asciidoc(1) output is not to your
+liking you can:
+
+1. Change the indentation and layout of configuration file markup
+   template sections. The `{empty}` attribute is useful for outputting
+   trailing blank lines in markup templates.
+
+2. Use https://www.html-tidy.org/HTML Tidy program to tidy
+   asciidoc(1) output. Example:
+
+   $ asciidoc -b docbook -o - mydoc.txt | tidy -indent -xml >mydoc.xml
+
+3. Use the `xmllint(1)` format option. Example:
+
+   $ xmllint --format mydoc.xml
+
+Supporting minor DocBook DTD variations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The conditional inclusion of DocBook SGML markup at the end of the
+distribution `docbook45.conf` file illustrates how to support minor
+DTD variations. The included sections override corresponding entries
+from preceding sections.
+
+Creating stand-alone HTML documents
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you've ever tried to send someone an HTML document that includes
+stylesheets and images you'll know that it's not as straight-forward
+as exchanging a single file.  AsciiDoc has options to create
+stand-alone documents containing embedded images, stylesheets and
+scripts.  The following AsciiDoc command creates a single file
+containing <<X66,embedded images>>, CSS stylesheets, and JavaScript
+(for table of contents and footnotes):
+
+  $ asciidoc -a data-uri -a icons -a toc -a max-width=55em article.txt
+
+You can view the HTML file here: {website}article-standalone.html
+
+Shipping stand-alone AsciiDoc source
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Reproducing presentation documents from someone else's source has one
+major problem: unless your configuration files are the same as the
+creator's you won't get the same output.
+
+The solution is to create a single backend specific configuration file
+using the asciidoc(1) `-c` (`--dump-conf`) command-line option. You
+then ship this file along with the AsciiDoc source document plus the
+`asciidoc.py` script. The only end user requirement is that they have
+Python installed (and that they consider you a trusted source). This
+example creates a composite HTML configuration file for `mydoc.txt`:
+
+  $ asciidoc -cb xhtml11 mydoc.txt > mydoc-xhtml11.conf
+
+Ship `mydoc.txt`, `mydoc-html.conf`, and `asciidoc.py`. With
+these three files (and a Python interpreter) the recipient can
+regenerate the HMTL output:
+
+  $ ./asciidoc.py -eb xhtml11 mydoc.txt
+
+The `-e` (`--no-conf`) option excludes the use of implicit
+configuration files, ensuring that only entries from the
+`mydoc-html.conf` configuration are used.
+
+Inserting blank space
+~~~~~~~~~~~~~~~~~~~~~
+Adjust your style sheets to add the correct separation between block
+elements. Inserting blank paragraphs containing a single non-breaking
+space character `{nbsp}` works but is an ad hoc solution compared
+to using style sheets.
+
+Closing open sections
+~~~~~~~~~~~~~~~~~~~~~
+You can close off section tags up to level `N` by calling the
+`eval::Section.setlevel(N)` system macro. This is useful if you
+want to include a section composed of raw markup. The following
+example includes a DocBook glossary division at the top section level
+(level 0):
+
+---------------------------------------------------------------------
+\ifdef::basebackend-docbook
+
+\eval::Section.setlevel(0)
+
++++++++++++++++++++++++++++++++
+<glossary>
+  <title>Glossary</title>
+  <glossdiv>
+  ...
+  </glossdiv>
+</glossary>
++++++++++++++++++++++++++++++++
+\endif::basebackend-docbook
+---------------------------------------------------------------------
+
+Validating output files
+~~~~~~~~~~~~~~~~~~~~~~~
+Use `xmllint(1)` to check the AsciiDoc generated markup is both well
+formed and valid. Here are some examples:
+
+  $ xmllint --nonet --noout --valid docbook-file.xml
+  $ xmllint --nonet --noout --valid xhtml11-file.html
+  $ xmllint --nonet --noout --valid --html html4-file.html
+
+The `--valid` option checks the file is valid against the document
+type's DTD, if the DTD is not installed in your system's catalog then
+it will be fetched from its Internet location. If you omit the
+`--valid` option the document will only be checked that it is well
+formed.
+
+The online https://validator.w3.org/#validate_by_uri+with_optionsW3C
+Markup Validation Service is the defacto standard when it comes to
+validating HTML (it validates all HTML standards including HTML5).

+Migration Notes
+---------------
+X53
+Version 7 to version 8
+~~~~~~~~~~~~~~~~~~~~~~
+- A new set of quotes has been introduced which may match inline text
+  in existing documents -- if they do you'll need to escape the
+  matched text with backslashes.
+- The index entry inline macro syntax has changed -- if your documents
+  include indexes you may need to edit them.
+- Replaced a2x(1) `--no-icons` and `--no-copy` options with their
+  negated equivalents: `--icons` and `--copy` respectively. The
+  default behavior has also changed -- the use of icons and copying of
+  icon and CSS files must be specified explicitly with the `--icons`
+  and `--copy` options.
+
+The rationale for the changes can be found in the AsciiDoc
+`CHANGELOG`.
+
+NOTE: If you want to disable unconstrained quotes, the new alternative
+constrained quotes syntax and the new index entry syntax then you can
+define the attribute `asciidoc7compatible` (for example by using the
+`-a asciidoc7compatible` command-line option).
+
+X38
+appendix
+Packager Notes
+--------------
+Read the `README` and `INSTALL` files (in the distribution root
+directory) for install prerequisites and procedures.  The distribution
+`Makefile.in` (used by `configure` to generate the `Makefile`) is the
+canonical installation procedure.
+
+
+X39
+appendix
+AsciiDoc Safe Mode
+-------------------
+AsciiDoc 'safe mode' skips potentially dangerous scripted sections in
+AsciiDoc source files by inhibiting the execution of arbitrary code or
+the inclusion of arbitrary files.
+
+The safe mode is disabled by default, it can be enabled with the
+asciidoc(1) `--safe` command-line option.
+
+.Safe mode constraints
+- `eval`, `sys` and `sys2` executable attributes and block macros are
+  not executed.
+- `include::<filename>` and `include1::<filename>` block macro
+  files must reside inside the parent file's directory.
+- `{include:<filename>}` executable attribute files must reside
+  inside the source document directory.
+- Passthrough Blocks are dropped.
+
+WARNING
+=====================================================================
+The safe mode is not designed to protect against unsafe AsciiDoc
+configuration files. Be especially careful when:
+
+1. Implementing filters.
+2. Implementing elements that don't escape special characters.
+3. Accepting configuration files from untrusted sources.
+=====================================================================
+
+
+appendix
+Using AsciiDoc with non-English Languages
+-----------------------------------------
+AsciiDoc can process UTF-8 character sets but there are some things
+you need to be aware of:
+
+- If you are generating output documents using a DocBook toolchain
+  then you should set the AsciiDoc `lang` attribute to the appropriate
+  language (it defaults to `en` (English)). This will ensure things
+  like table of contents, figure and table captions and admonition
+  captions are output in the specified language.  For example:
+
+  $ a2x -a lang=es doc/article.txt
+
+- If you are outputting HTML directly from asciidoc(1) you'll
+  need to set the various `*_caption` attributes to match your target
+  language (see the list of captions and titles in the `attributes`
+  section of the distribution `lang-*.conf` files). The easiest way is
+  to create a language `.conf` file (see the AsciiDoc's `lang-en.conf`
+  file).
++
+NOTE: You still use the 'NOTE', 'CAUTION', 'TIP', 'WARNING',
+'IMPORTANT' captions in the AsciiDoc source, they get translated in
+the HTML output file.
+
+- asciidoc(1) automatically loads configuration files named like
+  `lang-<lang>.conf` where `<lang>` is a two letter language code that
+  matches the current AsciiDoc `lang` attribute. See also
+  <<X27,Configuration File Names and Locations>>.
+
+
+appendix
+Vim Syntax Highlighter
+----------------------
+Syntax highlighting is incredibly useful, in addition to making
+reading AsciiDoc documents much easier syntax highlighting also helps
+you catch AsciiDoc syntax errors as you write your documents.
+
+If you use the Vim editor, it comes with an
+https://github.com/vim/vim/blob/master/runtime/syntax/asciidoc.vimAsciiDoc
+syntax highlighter pre-included. By default, it will activate for
+files that use the .asciidoc or .adoc file extensions.
+
+Alternatively, to enable syntax highlighting for the current document or
+other extensions:
+
+- Put a Vim 'autocmd' in your Vim configuration file (see the
+  <<X61,example vimrc file>>).
+- or execute the Vim command `:set syntax=asciidoc`.
+- or add the following line to the end of you AsciiDoc source files:
+
+  // vim: set syntax=asciidoc:

+Diagnostics
+-----------
+The `asciidoc(1)` `--verbose` command-line option prints additional
+information to stderr: files processed, filters processed, warnings,
+system attribute evaluation.
+
+A special attribute named 'trace' enables the output of
+element-by-element diagnostic messages detailing output markup
+generation to stderr.  The 'trace' attribute can be set on the
+command-line or from within the document using <<X18,Attribute
+Entries>> (the latter allows tracing to be confined to specific
+portions of the document).
+
+- Trace messages print the source file name and line number and the
+  trace name followed by related markup.
+- 'trace names' are normally the names of AsciiDoc elements (see the
+  list below).
+- The trace message is only printed if the 'trace' attribute value
+  matches the start of a 'trace name'. The 'trace' attribute value can
+  be any Python regular expression.  If a trace value is not specified
+  all trace messages will be printed (this can result in large amounts
+  of output if applied to the whole document).
+
+- In the case of inline substitutions:
+  * The text before and after the substitution is printed; the before
+    text is preceded by a line containing `<<<` and the after text by
+    a line containing `>>>`.
+  * The 'subs' trace value is an alias for all inline substitutions.

+Backend Attributes
+------------------
+This table contains a list of optional attributes that influence the
+generated outputs.
+
+cols="1e,1,5a",frame="topbot",options="header"
+|====================================================================
+|Name |Backends |Description
+
+|badges |xhtml11, html5 |
+Link badges ('XHTML 1.1' and 'CSS') in document footers. By default
+badges are omitted ('badges' is undefined).
+
+NOTE: The path names of images, icons and scripts are relative path
+names to the output document not the source document.
+
+|data-uri |xhtml11, html5 |
+Embed images using the <<X66,data: uri scheme>>.
+
+|css-signature |html5, xhtml11 |
+Set a 'CSS signature' for the document (sets the 'id' attribute of the
+HTML 'body' element). CSS signatures provide a mechanism that allows
+users to personalize the document appearance. The term 'CSS signature'
+was https://juicystudio.com/article/css-selectors.phpcoined by
+Eric Meyer.
+
+
+|disable-javascript |xhtml11, html5 |
+If the `disable-javascript` attribute is defined the `asciidoc.js`
+JavaScript is not embedded or linked to the output document.  By
+default AsciiDoc automatically embeds or links the `asciidoc.js`
+JavaScript to the output document. The script dynamically generates
+<<X91,table of contents>> and <<X92,footnotes>>.
+
+|X97 docinfo, docinfo1, docinfo2 |All backends |
+These three attributes control which <<X87,document information
+files>> will be included in the the header of the output file:
+
+docinfo:: Include `<filename>-docinfo.<ext>`
+docinfo1:: Include `docinfo.<ext>`
+docinfo2:: Include `docinfo.<ext>` and `<filename>-docinfo.<ext>`
+
+Where `<filename>` is the file name (sans extension) of the AsciiDoc
+input file and `<ext>` is `.html` for HTML outputs or `.xml` for
+DocBook outputs. If the input file is the standard input then the
+output file name is used. The following example will include the
+`mydoc-docinfo.xml` docinfo file in the DocBook `mydoc.xml` output
+file:
+
+  $ asciidoc -a docinfo -b docbook mydoc.txt
+
+This next example will include `docinfo.html` and `mydoc-docinfo.html`
+docinfo files in the HTML output file:
+
+  $ asciidoc -a docinfo2 -b html4 mydoc.txt
+
+
+|X54encoding |html4, html5, xhtml11, docbook |
+Set the input and output document character set encoding. For example
+the `--attribute encoding=ISO-8859-1` command-line option will set the
+character set encoding to `ISO-8859-1`.
+
+- The default encoding is UTF-8.
+- This attribute specifies the character set in the output document.
+- The encoding name must correspond to a Python codec name or alias.
+- The 'encoding' attribute can be set using an AttributeEntry inside
+  the document header. For example:
+
+  :encoding: ISO-8859-1
+
+|hr |html4 |
+Defines the 'html4' inter-section horizontal ruler element. By default
+'html4' top level sections are separated by a horizontal ruler
+element, undefine this attribute or set it to an empty string if you
+do not want them. The default 'html4' backend value for the 'hr'
+attribute is `<hr>`.
+
+|X45icons |xhtml11, html5 |
+Link admonition paragraph and admonition block icon images and badge
+images. By default 'icons' is undefined and text is used in place of
+icon images.
+
+|X44iconsdir |html4, html5, xhtml11, docbook |
+The name of the directory containing linked admonition icons,
+navigation icons and the `callouts` sub-directory (the `callouts`
+sub-directory contains <<X105,callout>> number images). 'iconsdir'
+defaults to `./images/icons`.  If admonition icons are embedded using
+the <<X66,data-uri>> scheme then the 'iconsdir' attribute defaults to
+the location of the icons installed in the AsciiDoc configuration
+directory.
+
+|imagesdir |html4, html5, xhtml11, docbook |
+If this attribute is defined it is prepended to the target image file
+name paths in inline and block image macros.
+
+|keywords, description, title |html4, html5, xhtml11 |
+The 'keywords' and 'description' attributes set the correspondingly
+named HTML meta tag contents; the 'title' attribute sets the HTML
+title tag contents.  Their principle use is for SEO (Search Engine
+Optimisation).  All three are optional, but if they are used they must
+appear in the document header (or on the command-line). If 'title' is
+not specified the AsciiDoc document title is used.
+
+|linkcss |html5, xhtml11 |
+Link CSS stylesheets and JavaScripts. By default 'linkcss' is
+undefined in which case stylesheets and scripts are automatically
+embedded in the output document.
+
+|X103max-width |html5, xhtml11 |
+Set the document maximum display width (sets the 'body' element CSS
+'max-width' property).
+
+|numbered |html4, html5, xhtml11, docbook (XSL Stylesheets) |
+Adds section numbers to section titles. The 'docbook' backend ignores
+'numbered' attribute entries after the document header.
+
+|plaintext | All backends |
+If this global attribute is defined all inline substitutions are
+suppressed and block indents are retained.  This option is useful when
+dealing with large amounts of imported plain text.
+
+|quirks |xhtml11 |
+Include the `xhtml11-quirks.conf` configuration file and
+`xhtml11-quirks.css` <<X35,stylesheet>> to work around IE6 browser
+incompatibilities. This feature is deprecated and its use is
+discouraged -- documents are still viewable in IE6 without it.
+
+|revremark |docbook |
+A short summary of changes in this document revision. Must be defined
+prior to the first document section. The document also needs to be
+dated to output this attribute.
+
+|footer-style |html4, html5, xhtml11 |
+Changes the "Last updated" field in the footer of the document or removes this
+field and the revision number (in the footer only). +
+Can take 3 values:
+
+- none : Don't display the "Last updated" and "Revision number" fields in the
+  footer of the document
+- revdate : The "Last updated" field's date in the footer will be the revision
+  date specified in the document (`revdate` attribute)
+- default (or any other value) : The "Last updated" field's date in the footer
+  will be the date of the input file modification
+
+This attribute can be set, for example, using `:footer-style: revdate` in the
+header of the file or using the `--attribute footer-style=revdate` command-line
+option.
+
+|scriptsdir |html5, xhtml11 |
+The name of the directory containing linked JavaScripts.
+See <<X35,HTML stylesheets and JavaScript locations>>.
+
+|sgml |docbook45 |
+The `--backend=docbook45` command-line option produces DocBook 4.5
+XML.  You can produce the older DocBook SGML format using the
+`--attribute sgml` command-line option.
+
+|stylesdir |html5, xhtml11 |
+The name of the directory containing linked or embedded
+<<X35,stylesheets>>.
+See <<X35,HTML stylesheets and JavaScript locations>>.
+
+|stylesheet |html5, xhtml11 |
+The file name of an optional additional CSS <<X35,stylesheet>>.
+
+|theme |html5, xhtml11 |
+Use alternative stylesheet (see <<X35,Stylesheets>>).
+
+|X91toc |html5, xhtml11, docbook (XSL Stylesheets) |
+Adds a table of contents to the start of an article or book document.
+The `toc` attribute can be specified using the `--attribute toc`
+command-line option or a `:toc:` attribute entry in the document
+header. The 'toc' attribute is defined by default when the 'docbook'
+backend is used. To disable table of contents generation undefine the
+'toc' attribute by putting a `:toc!:` attribute entry in the document
+header or from the command-line with an `--attribute toc!` option.
+
+*xhtml11 and html5 backends*
+
+- JavaScript needs to be enabled in your browser.
+- The following example generates a numbered table of contents using a
+  JavaScript embedded in the `mydoc.html` output document:
+
+  $ asciidoc -a toc -a numbered mydoc.txt
+
+|toc2 |html5, xhtml11 |
+Adds a scrollable table of contents in the left hand margin of an
+article or book document. Use the 'max-width' attribute to change the
+content width. In all other respects behaves the same as the 'toc'
+attribute.
+
+|toc-placement |html5, xhtml11 |
+When set to 'auto' (the default value) asciidoc(1) will place the
+table of contents in the document header. When 'toc-placement' is set
+to 'manual' the TOC can be positioned anywhere in the document by
+placing the `toc::` block macro at the point you want the TOC to
+appear.
+
+NOTE: If you use 'toc-placement' then you also have to define the
+<<X91,toc>> attribute.
+
+|toc-title |html5, xhtml11 |
+Sets the table of contents title (defaults to 'Table of Contents').
+
+|toclevels |html5, xhtml11 |
+Sets the number of title levels (1..4) reported in the table of
+contents (see the 'toc' attribute above). Defaults to 2 and must be
+used with the 'toc' attribute. Example usage:
+
+  $ asciidoc -a toc -a toclevels=3 doc/asciidoc.txt

+This document is an AsciiDoc multi-part book skeleton containing
+briefly annotated element placeholders plus a couple of example index
+entries and footnotes. Books are normally used to generate DocBook
+markup and the preface, appendix, bibliography, glossary and index
+section titles are significant ('specialsections').
+
+NOTE: Multi-part books differ from all other AsciiDoc document formats
+in that top level sections (dedication, preface, book parts,
+appendices, bibliography, glossary, index) must be level zero headings
+(not level one).

+LaTeX Filter
+============
+
+:blogpost-status: published
+:blogpost-doctype: article
+:blogpost-posttype: page
+:blogpost-categories: AsciiDoc,LaTeX,python
+
+The AsciiDoc distribution includes a LaTeX filter that translates LaTeX source
+to an image which is automatically inserted into the AsciiDoc output document.
+Although it can accept any LaTeX source, the primary use is to render
+mathematical formulae (see the examples below).  The filter implements the
+'latex' Listing block and Paragraph styles.
+
+Two image formats are supported; PNG and SVG. PNG is the default since that
+was the first format that this filter supported. However, SVG is a better
+format since it's scalable. Using SVG make formulas look good in both PDFs
+and on web pages. SVG will also scale well when zooming in on a web page for
+example. It is recommended to always use the SVG format. This can be done by
+setting the 'imgfmt' parameter to 'svg', as is done below. An even better way
+is to set the global attribute 'latex-imgfmt' to 'svg'. Then SVG will be used
+for all formulas.
+
+This LaTeX paragraph:
+
+listing

+\begin{equation*}
+y = \int_0^\infty \gamma^2 \cos(x) dx
+\end{equation*}
+---------------------------------------------------------------------
+
+Compare the formula above, which is rendered as an SVG image, to the formula
+below which has been rendered as a PNG image. The difference will be most
+notable if zooming in on a web page, printing the web page or when rendering
+the document as a PDF.

+
+Using the Filter
+----------------
+- The LaTeX filter is invoked by setting the Listing block or
+  Paragraph style (the first positional block attribute) to 'latex'.
+- The second positional attribute (named 'target' is optional, it sets
+  the name of the generated image file. If this is not supplied a
+  file name like `{docname}__{target-number}.{imgfmt}` is synthesised
+  (where `{docname}` is the document file name, `{target-number}`
+  is an integer number and `{imgfmt}` is the image format (png or svg).
+- The third positional attribute, named 'dpi', is also optional; it is
+  an integer number that sets the output resolution in dots per inch
+  for a PNG image. It is ignored for an SVG image.
+- The image format to use can be selected by setting the 'imgfmt'
+  parameter or by globally setting the 'latex-imgfmt' attribute.
+  Setting it to 'svg' will render SVG images and setting it to 'png'
+  will render PNG images. The default is 'png'.
+
+Because the LaTeX images are rendered using the image block templates
+you can also use the optional named image block attributes (see
+link:userguide.html#X55Image macro attributes in the AsciiDoc User
+Guide).
+
+TIP
+=====================================================================
+You can also change the image size using the following LaTeX commands:
+
+  \tiny
+  \scriptsize
+  \footnotesize
+  \small
+  \normalsize
+  \large
+  \Large
+  \LARGE
+  \huge
+
+For example:
+
+  latex
+  \Large $y = \int_0^\infty \gamma^2 \cos(x) dx$
+
+The `\Large` command is outside the `$` math delimiters.
+
+=====================================================================
+
+The filter (`./filters/latex/latex2img.py`) can be used outside
+AsciiDoc to convert LaTeX source to images.
+
+Execute the following command to see how to use it:
+
+  $ ./filters/latex/latex2img.py --help
+
+
+Limitations
+-----------
+- The `asciidoc(1)` input and output files cannot both be `-` (stdin
+  and stdout), either the input or output files (or both) must be a
+  named file.
+
+
+Installation
+------------
+In addition to AsciiDoc you will need to have `latex(1)`,
+`dvipng(1)` (for PNG) and/or `dvisvgm(1)` (for SVG) installed.

+====================
+

+capability has been added to AsciiDoc for users who are more familar
+with or prefer LaTeX math formulas to the
+https://asciidoc.org/asciimath.htmlASCIIMath
+notation.
+
+'LaTeXMathML' is a derivative of
+https://asciidoc.org/asciimath.htmlASCIIMath -- in
+terms of usage the only difference it that you use the `latexmath`
+attribute instead of the `asciimath` attribute.
+
+'LaTeXMathML' processes LaTeX math formulas not arbitrary LaTeX (as
+`dblatex(1)` does). See the

+Source Code Highlight Filter
+============================
+
+The AsciiDoc distribution includes a 'source' filter for highlighting
+code syntax.
+
+
+DocBook Outputs
+---------------
+AsciiDoc encloses the source code in a DocBook 'programlisting'
+element and leaves source code highlighting to the DocBook toolchain
+(dblatex has a particularly nice programlisting highlighter). The
+DocBook programlisting element is assigned two attributes:
+
+. The 'language' attribute is set to the AsciiDoc 'language'
+  attribute.
+. The 'linenumbering' attribute is set to the AsciiDoc 'src_numbered'
+  attribute ('numbered' or 'unnumbered').
+
+
+HTML Outputs
+------------
+You have the choice of three HTML source code highlighters, your
+selection is determined by the 'source-highlighter' attribute (defaults
+to 'source-highlight'):
+
+NOTE: Set the 'source-highlighter' attribute from the asciidoc(1)
+command-line or in the document header (not in the document body,
+because the configuration file conditional macros are processed at
+load time).
+
+=== GNU Source Highlight
+The default highlighter is the
+https://www.gnu.org/software/src-highlite/GNU source-highlight which
+can highlight 'html4', 'html5' and 'xhtml11' outputs.  The GNU
+source-highlight must be installed and the 'source-highlight' command
+must reside in the shell search 'PATH'.
+
+=== Highlight
+You can use
+http://www.andre-simon.de/doku/highlight/en/highlight.htmlHighlight
+syntax highlighter for 'xhtml11', 'html5' and 'html4' outputs (set the
+'source-highlighter' attribute to 'highlighter').
+
+- The 'highlight' command must reside in the shell search 'PATH'.
+- To make Highlighter your default highlighter put the following line
+  your `~/.asciidoc/asciidoc.conf` file:
+
+  source-highlighter=highlight
+
+- The AsciiDoc 'encoding' attribute is passed to Highlighter using the
+  `--encoding` command-line option.
+
+=== Pygments
+The https://pygments.org/Pygments syntax highlighter can be used for
+'xhtml11' and 'html5' outputs (set the 'source-highlighter' attribute
+to 'pygments').
+
+- The 'pygmentize' command must reside in the shell search 'PATH'.
+- You can customize Pygments CSS styles by editing
+  `./stylesheets/pygments.css`. The `pygments.css` CSS file was
+  generated with:
+
+  from pygments.formatters import HtmlFormatter
+  print HtmlFormatter().get_style_defs('.highlight')
+
+- To make Pygments your default highlighter put the following line
+  your `~/.asciidoc/asciidoc.conf` file:
+
+  source-highlighter=pygments
+
+- The AsciiDoc 'encoding' attribute is passed to Pygments using the
+  `-O` command-line option.
+
+
+Block attributes
+----------------
+The following attributes can be included in source code block
+attribute lists.
+
+- 'style' and 'language' are mandatory.
+- 'style', 'language' and 'src_numbered' are the first three
+  positional attributes in that order.
+- The 'args' attribute allows the inclusion of arbitrary (highlighter
+  dependent) command options.
+
+//
+
+style::
+  Set to 'source'.
+language::
+  The source code language name.
++
+NOTE: The language names vary between highlighters -- consult the
+selected highlighter manual.
+
+src_numbered::
+  Set to 'numbered' to include line numbers.
+src_tab::
+  Set tab size (GNU source-highlight only).
+args::
+  Include this attribute value in the highlighter command-line (HTML
+  outputs) or in the `programlisting` element (DocBook).
+
+
+Testing
+-------
+Test the filter by converting the test file to HTML with AsciiDoc:
+
+  $ asciidoc -v ./filters/source/source-highlight-filter-test.txt
+  $ firefox ./filters/source/source-highlight-filter-test.html &

+
+TIP
+=====
+- If the source 'language' attribute has been set (using an
+  'AttributeEntry' or from the command-line) you don't have to specify
+  it in each source code block.
+- You should place callout markers inside source code comments to
+  ensure they are not misinterpreted and mangled by the highlighter.

-  auto-generated IDs
-  http://groups.google.com/group/asciidoc/browse_thread/thread/33e99b78e2472122are
-  replaced by their nearest ascii equivalents (to work around DocBook
-  processor limitations).
-- Added global 'blockname' attribute which is dynamically updated to

-  list.
-- If the delimited block 'skip' option is set then do not consume
-  block title and attributes. This makes it possible for the comment
-  delimited blocks to use an attribute list (previously the comment
-  delimited block was hardwired to skip preceding attributes and
-  titles). See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/e92a75abcc382701discussion
-  list.
-- Added `backend-confdir` intrinsic attribute.

-- *FIXED*: Leaky file handles in a2x and music and latex filters which
-  created incompatibility problems for Jython.
-- *FIXED*: All Python filters are executed with the same Python
-  interpreter that executes the asciidoc parent (previously filters
-  were hardwired to execute the 'python' interpreter). This prevents
-  http://groups.google.com/group/asciidoc/browse_thread/thread/14e8fcb289a135b/3af3b4e57b827c78?lnk=gst&q=archlinux#3af3b4e57b827c78Python

-
-Version 8.6.6 (2011-09-04)
---------------------------
-.Release highlights
-- The AsciiDoc plugin architecture has been enhanced, unified and
-  extended:
-  * Plugin commands have been added to the asciidoc(1) `--backend`
-    option.
-  * An asciidoc(1) `--theme` option has been implemented to specify a
-    theme and to manage theme plugins.
-  * A plugin 'build' command (for creating plugins) added.
-  * 'build', 'install', 'list' and 'remove' plugin commands are all
-    recognized by asciidoc(1) `--backend`, `--filter` and `--theme`
-    options.
-- A security update by Kenny MacDermid removes the use of `eval()` on
-  untrusted input (to disallow code malicious execution).
-
-.All additions and changes
-- 'xhtml11', 'html5': Made verse and quote block text darker to print
-  legibly in Google Chrome browser.
-- Added plugin 'build' command for plugin file creation.
-- Merged `--help plugins` back to `--help manpage` so it matches the
-  asciidoc(1) manpage.
-- The `--filter` command-line option can specify the name of filters
-  that will be unconditionally loaded.
-- If a filter directory contains a file named `__noautoload__` then
-  the filter is not automatically loaded (you can used the `--filter`
-  command-line option to override this behavior).
-- tests: Add Italian language tests.  Patch submitted by Simon
-  Ruderich. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/5e2e6f4dd740d51a
-- tests: Add tests for localized man pages.  Patch submitted by Simon
-  Ruderich. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/5e2e6f4dd740d51a
-- If the section name is prefixed with a '+' character then the
-  section contents is appended to the contents of an already existing
-  same-named section (the default behavior is to replace the the
-  section).
-- If a configuration file section named 'docinfo' is loaded then it
-  will be included in the document header.  Typically the 'docinfo'
-  section name will be prefixed with a '+' character so that it is
-  appended to (rather than replace) other 'docinfo' sections.
-- Added `{sp}` intrinsic attribute for single space character.  See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/a839aa01db0765d2
-- Fixed TOC and footnotes generator. Patch submitted by Will.  See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/734ac5afed736987
-- The `asciidoc-confdir` attribute is set to the asciidoc executable
-  directory if it contains global configuration files i.e. a local
-  asciidoc installation.

-  backend configuration file is not found.
-- latex filter: write MD5 file after successful PNG file generation.
-  Always delete temp files irrespective of outcome.

-  Krämer. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/6436788a10561851

-- Added verbose message for `ifeval::` macro evaluation.
-- Added test case for `ifeval::` evaluation.
-- Security update to remove the use of `eval()` on untrusted input (to
-  disallow code malicious execution).  Patch submitted by Kenny

-  http://groups.google.com/group/asciidoc/browse_thread/thread/ec8e8481eb0e27b0/d1c035092b5bb7a4?lnk=gst&q=caption+option#d1c035092b5bb7a4
-- a2x: Pass `--format` option value to asciidoc as 'a2x-format'
-  attribute.  Patch submitted by Lex Trotman
-  (http://groups.google.com/group/asciidoc/browse_thread/thread/3e177b84bc133ca9/659796dfadad30ea?lnk=gst&q=a2x+format#659796dfadad30ea).
-- Added two FAQs submitted by Lex Trotman. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/16d3fb9672a408e7
-- html5,xhtml11: Implemented themes directory structure.

-- xhtml11, html5: Remove necessity for separate manpage CSS files.
-- Added 'css-signature' attribute to tests.
-- Add 'css-signature' attribute to set a CSS signature for the
-  document.  Patch submitted by Peg Russell, see:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/bacbf8aeb8ad6a3a

-  content does not obscure the the TOC.  Patch submitted by Lionel
-  Orry, see: http://code.google.com/p/asciidoc/issues/detail?id=8

-- *FIXED*: Plugin install command: Delete backend directory is install
-  fails.
-- *FIXED*: Plugin install command: Fixed bug extracting binary files
-  on Windows (reported by Jean-Michel Inglebert).
-- *FIXED*: tests: Skip blank sections in testasciidoc.conf test
-  configuration file instead of throwing an exception (reported by
-  Jean-Michel Inglebert).
-- *FIXED*: If a plugin Zip file does not contain file permissions
-  (probably because it was created under Windows) then install it
-  using the default permissions.
-- *FIXED*: Fixed missing quote in preceding LaTeX filter patch. Fix
-  submitted by Simon Ruderich. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/6436788a10561851
-- *FIXED*: Some path attributes were processed as escaped Python
-  strings which could result in corrupted path names with backslash
-  separated Windows path names. Reported by Will. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/e8f3938bcb4c8bb4/44d13113a35738ef
-- *FIXED*: Vertically spanned table cells resulted in incorrect column

-  McCurry:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/8c111f1046b33691/158a944cf4d5ff0d?lnk=gst&q=latex+escapes#158a944cf4d5ff0d
-- *FIXED*: When using slidy backend, display of characters with
-  accents is wrong because of 'meta http-equiv' line missing. Reported
-  by Fabrice Flore-Thebault.  See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/eaf25f21d1da180a

-
-Version 8.6.5 (2011-05-20)
---------------------------
-.Release highlights
-- The addition of an 'html5' backend to generate HTML 5 output. Apart
-  from the inclusion of 'audio' and 'video' block macros the 'html5'
-  backend is functionally identical to the 'xhtml11' backend.
-
-- A new 'flask' theme for 'xhtml11' and 'html5' backends inspired by
-  the http://flask.pocoo.org/docs/Flask website styling (see 'toc2'
-  example in the next item below).
-
-- The new 'toc2' attribute generates a table of contents in
-  the left hand margin ('xhtml11' and 'html5' backends).
-  link:article-html5-toc2.htmlThis example was generated using
-  the following command:
-
-  asciidoc -b html5 -a icons -a toc2 -a theme=flask article.txt
-
-- `a2x(1)` now has a flexible mechanism for copying arbitrary
-  resource files to HTML based outputs -- this is very handy for
-  generating EPUB files with embedded fonts and other resources.
-
-  * The `a2x(1)` `--resource` option can be used to inject any file
-    into EPUB output documents e.g. CSS resources such as fonts and
-    background images.
-  * Explicitly specified resources are added to the EPUB OPF manifest
-    automatically.
-  * You can explicitly specify file extension MIME types.
-  * The enhanced resource processing works around a couple of DocBook
-    XSL bugs (see link:epub-notes.htmlEPUB Notes).
-
-.All additions and changes
-- A new 'flask' theme for 'xhtml11' and 'html5' backends.  A shameless
-  knock-off of the http://flask.pocoo.org/docs/Flask website
-  styling.
-- Added HTML 5 article with 'toc2' table of contents to the example on
-  the AsciiDoc website home page.
-- Added 'filters' and 'topics' help topics.  Fixed documentation
-  errors in help text.  Patch submitted by Lionel Orry, see:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/9da9d48a6461ff14
-- Pass parent configuration files, command-line attributes and header
-  attributes to table asciidoc filters. Based on patch submitted by
-  Simon Ruderich, see:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/5c792cbb395b753b
-- Allow a 'title' attribute entry in the document header so that HTML
-  backends can set the 'title' element separately from the displayed
-  document title (the 'doctitle' attribute).
-- Pass 'lang' attribute to 'asciidoc' table style filter. Patch
-  submitted by Simon Ruderich, see:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/e2100b7cb29283ce
-- xhtml11,html5: Added 'toc2' attribute which generates a scrollable
-  table of contents in the left hand margin. Based on customized CSS
-  written by Suraj Kurapati, see
-  http://groups.google.com/group/asciidoc/browse_thread/thread/c5e30ee5555877f5
-- Added 'asciidoc-confdir' intrinsic attribute which expands to the
-  global conf directory.
-- Documented that you can specify multiple CSS files with the a2x(1)
-  `--stylesheet` command option. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/baf3218551d05a05
-- Improved xhtml11 backend's table of contents generation latency.
-  Patch submitted by Hongli Lai. See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/5a7fe64fbfd65ad
-- Added html5 backend.
-- For consistency converted all DOS formatted configuration and text
-  files to UNIX format.
-- html4: Added ability to use 'role' attribute with most block
-  elements. Patch contributed by Simon Ruderich.  See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/5620ba634fdb030a
-- Added Dutch language configuration file and accompanying test file
-  (contributed by Dag Wieers, see
-  http://groups.google.com/group/asciidoc/browse_thread/thread/f969b9ce987d7f5d).
-- Configuration files are loaded in two passes when the -e
-  command-line option is used (the same behavior as when the -e option
-  is not used). Patch submitted by haad. See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/cd0f47495fd04181
-  and
-  http://code.google.com/p/asciidoc/issues/detail?id=6&q=label%3APriority-Medium
-- Documented how to include embedded fonts in an EPUB document.
-- a2x: Added `.<ext>=<mimetype>` resource specifier syntax.
-- a2x: Enable admonition icons in example EPUBs.
-- a2x: allow environment variables and tilde home directories in
-  resource manifest files.
-- a2x: don't process non-existent resource directories.
-- a2x: assume resource option is a directory if the name ends with a
-  directory separator.
-- a2x: Added a new syntax to the `--resource` option specifier which
-  allows the destination path to be specified.
-- a2x: Copy resources referenced in the OPF and resources referenced
-  by the generated HTML (in theory DocBook XSL should ensure they are
-  identical but this is not always the case e.g.
-  http://sourceforge.net/tracker/?func=detail&atid=373747&aid=2854075&group_id=21935).
-- Drop border from callout list image links.
-- html4: Moved manpage NAME section out of header so that the name
-  section is rendered when the asciidoc(1) `--no-header-footer` option
-  is specified (so that manpages processed blogpost include the NAME
-  section).
-- Vim syntax highlighter: TODO markers now appear in list items and
-  literal paragraphs and blocks.
-- Constrained quotes can now be bounded on the left by a } character.
-  See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/b24cc3362f35b801
-- Added text-decoration roles (underline, overline, line-through,
-  blink) for xhtml11 and html5 outputs.
-
-.Bug fixes
-- *FIXED*: epubcheck 1.1 previously issued a warning for files not
-  registered in the manifest (epubcheck 1.0.5 did not). This resulted
-  in a problem compiling the adventures-of-sherlock-holmes.txt example
-  (the `underline.png` resource was not in the manifest).
-
-
-Version 8.6.4 (2011-02-20)
---------------------------

-  (thanks to Henrik Maier for this patch).
-- Added `ifeval::` system macro (thanks to Henrik Maier for
-  suggesting this feature).
-- The image 'scale' attribute sets the DocBook 'imagedata' element
-  'scale' attribute.  Patch submitted by Henrik Maier.
-- DocBook 'preface', 'colophon' and 'dedication' style section titles
-  now work. Based on patch submitted by Henrik Maier.
-- 'a2x': Do not inject xsltproc parameters if they were specified on
-  the command-line (parameter double-ups generate xsltproc 'Global
-  parameter already defined' errors).
-- 'a2x': Refactored xsltproc parameter injection.
-- 'a2x': articles chunked at section level by default.
-- 'attributes', 'titles' and 'specialcharacters' sections are now read
-  from the local `asciidoc.conf` file before the header is parsed.
-  This fixes a regression problem. See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/1b3f88f1f8118ab3
-- Document header attributes take precedence over configuration file
-  attributes.
-- Refactored 'music', 'graphviz' and 'latex' filter configurations.

-- Renamed paragraph 'default' style to 'normal'.
-- Updated `--help` option text.
-- 'a2x': The `asciidoc_opts`, `dblatex_opts`, `fop_opts` and
-  `xsltproc_opts` command-line options can be specified multiple
-  times.  This makes embedding multiple 'a2x' options in document
-  headers easier to manage and less error prone.
-- Added ASCIIMathML and LaTeXMathML support to slidy backend.
-- Pass the 'encoding' attribute to the Pygments source highlight
-  filter command.
-- 'a2x': HTML Help `.hhk` file named after AsciiDoc source file.

-
-.Bug fixes
-- *FIXED*: Sometimes double backquotes were misinterpreted as inline
-  literal macros.  See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/f510ea82a88aaee8
-- *FIXED*: Regression in 8.6.2: command-line attributes were not
-  available to the global asciidoc.conf.
-- *FIXED*: Postponed document title substitutions until backend conf
-  files have been loaded (8.6.2 regression). See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/42b63ce90c2563b8
-- *FIXED*: The XSL Stylesheets customizations were preventing chapter
-  and section level TOCs from being generated when using XSL
-  Stylesheets via 'a2x'.  See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/42b63ce90c2563b8
-- *FIXED*: ``UnicodeDecodeError: \'ascii' codec can't decode byte''
-  error.  This error is due to a limitation in the Python HTMLParser
-  module, see: http://bugs.python.org/issue3932
-- *FIXED*: Broken `--no-conf` option (8.6.2 regression).
-- *FIXED*: Regression in 8.6.2: configuration attribute entries set in
-  the document header may cause a 'FAILED: incomplete configuration
-  files' error.
-- *FIXED*: 'html4': corrected self closed meta tags.
-- *FIXED*: 'a2x' regression in 8.6.2: HTML Help `.hhp` file name had
-  reverted to default name instead of the AsciiDoc source file name.
-  See:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/dedc961b23e9ac56
-- *FIXED*: Attributes in man page title caused it to be dropped
-  resulting in invalid DocBook output.
-- *FIXED*: `make uninstall` now deletes the `asciidoc.1` and `a2x.1`
-  man pages.

-  introductions.
-- Comment lines substitute special characters only.
-- Backend specific global configuration files (all except
-  `asciidoc.conf`) are loaded *after* the header has been parsed --
-  virtually any attribute can now be specified in the document header.
-- 'xhtml11': Volnitsky theme: allow bulleted lists to have intervening
-  children.
-- 'xhtml11': refactored CSS font-family rules to start of file.
-- 'xhtml11': list bullets colored gray.
-- 'ifdef' and 'ifndef' system block macros accept multiple attribute
-  names: multiple names separated by commas are 'ored'; multiple

-- 'xhtml11': Volnitsky theme: set max-width on labeled lists.
-- Vim syntax highlighter: Entities inside quoted text are now
-  highlighted.
-- Added 'role' and 'id' attributes to HTML outputs generated by
-  'OpenBlocks'.

-  and control inclusion of a shared docinfo file. See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/c948697943432e24
-- Vim syntax highlighter highlights multi-name conditional attributes.
-- LaTeX backend patch submitted by Andreas Hermann Braml (see

-- Implemented 'backend aliases'; renamed `docbook.conf` to
-  `docbook45.conf` and aliased 'docbook45' backend to 'docbook';

-  source document that where not in the search 'PATH' where not found.
-- *FIXED*: Volnitsky theme: Verseblock font set normal instead of
-  monospaced.
-- *FIXED*: 'xhtml11': Callout icons were not rendered as Data URIs
-  when 'icons' and 'data-uri' attributes were specified.
-- *FIXED*: Long standing bug: nested include macros did not restore

-- *FIXED*: 'html4': set preamble ID anchor.
-- *FIXED*: 'xhtml11': dropped unusable 'id' and 'role' attributes from
-  preamble template.
-- *FIXED*: Bug in multi-name conditional attributes e.g. `{x,y#}`

-  whether icons are enabled or not.  Reported by Michael Wild:
-  http://groups.google.com/group/asciidoc/browse_thread/thread/59a610068e4acb58
-
-
-Version 8.6.1 (2010-08-22)
---------------------------
-.Additions and changes
-- 'a2x': `--resource-dir` option renamed to `--resource`.
-- 'a2x': `--resource` option accepts both file and directory names.
-- 'a2x': Added `-m,--resource-manifest` option.
-- Added Vim syntax highlighting for quote attribute lists.
-- Load 'asciidoc.conf' from all configuration directories before any
-  other configuration files. This ensures that attributes used for
-  conditional inclusion are set before backend configuration files are
-  processed. Previously if you wanted to control global conf file
-  inclusion your only choice was to modify the global 'asciidoc.conf'
-  file.
-- AsciiDoc 'Quote element' attributes have been simplified and
-  generalized -- positional color and size attributes and named 'role'
-  attribute have been replaced by a single positional attribute.
-
-.Bug fixes
-- *FIXED*: 'testasciidoc.py': `BACKEND` command argument was being
-  ignored.
-- *FIXED*: Broken 'docinfo' file functionality in 'html4' and
-  'xhtml11' backends (previously the docinfo file was included in
-  the 'body' instead of the 'header').
-
-Regression issues
-~~~~~~~~~~~~~~~~~
-This release breaks compatibility with quoted element positional color
-and size attributes (HTML backends). To revert to the deprecated quote
-behavior define the 'deprecated-quotes' attribute in the global
-`asciidoc.conf` file or on the command-line.  For a more detailed
-explanation of the rationale behind this change see
-http://groups.google.com/group/asciidoc/browse_thread/thread/b22603bfb879418c.
-
-
-Version 8.6.0 (2010-08-16)
---------------------------
-.Additions and changes
-- The AsciiDoc distribution can now be built ``out of the box''
-  from the distribution tarball or the Mercurial repository
-  (provided you have the requisite build applications installed).
-- The global configuration files directory is ignored by both
-  'asciidoc' and 'a2x' if AsciiDoc configuration files are installed
-  in the same directory as the asciidoc executable.  This change
-  allows both a system wide copy and multiple local copies of AsciiDoc
-  to coexist on the same host PC.
-- CSS 'quirks' mode is no longer the default 'xhtml11' output
-  (http://groups.google.com/group/asciidoc/browse_thread/thread/1c02d27d49221aa2).
-- Relaxed anchor ID name syntax
-  (http://groups.google.com/group/asciidoc/browse_thread/thread/5f3e825c74ed30c).
-- Added document files: `doc/epub-notes.txt`,
-  `doc/publishing-ebooks-with-asciidoc.txt`.
-- 'a2x': If all other resource locations are exhausted then recursively
-  search directories named 'images' and 'stylesheets' in the
-  'asciidoc' configuration files directory.
-- 'a2x': options can also be set in the AsciiDoc source file. If the
-  source file contains a line beginning with '// a2x:' then the
-  remainder of the line will be treated as a2x command-line options.
-- Added dblatex table-width processing instruction -- tables generated
-  by dblatex now observe the AsciiDoc table width as a percentage
-  (thanks to Gustav Broberg for suggesting this enhancement).
-- 'a2x': Don't exit if the `--epubcheck` option is set and 'epubcheck'
-  is missing, issue warning and continue.
-- Added a global 'plaintext' attribute for dealing with large amounts
-  of imported text.
-- The author name format has been relaxed, if the the author does not
-  match the formal specification then it is assigned to the
-  'firstname' attribute (previously asciidoc exited with an error
-  message).
-- FAQ and documentation updates.
-- Refactored chunked.xsl and epub.xsl files.
-- Exchanged article.epub for more relevant book.epub on website.
-- Put asciidoc.epub User Guide on website.
-- 'a2x': Chunking EPUB and HTML outputs set to a per chapter basis and
-  the first chapter is separate from preceding contents.
-- Changed dates format in example article and books to suppress EPUB
-  validation error.
-- Added 'style' and 'role' CSS classes to xhtml11 section templates.
-- Added the 'role' element to xhtml11 backend block templates.
-- Suppressed md5 module deprecation warning from music and Graphviz filters.
-- Pygments (http://pygments.org/) option added to source code
-  highlight filter.  Based on Pygments source code filter written by
-  David Hajage
-  (http://groups.google.com/group/asciidoc/browse_thread/thread/d8d042f5a3021369/8934ebbb8cb7144b).
-- xhtml11: Added a new theme (volnitsky). Written and contributed by
-  Leonid V. Volnitsky.
-- xhtml11: Set body element class name to document type.
-- Added refentryinfo element and contents (including revdate) to man
-  page DocBook output. Man pages are now dated using the revdate
-  attribute value if it has been defined.  Based on patch supplied by
-  Rainer Muller
-  http://groups.google.com/group/asciidoc/browse_frm/thread/319e5cd94493e330/3fcb83fab067af42.
-- Added `{template:...}` system attribute.
-- Table of contents attribute 'toc' can now be specified in the
-  document header.
-- Reimplemented music and latex filter -m option functionality when
-  the input is stdin using MD5 checksums.
-- Added 'latex' filter.
-- Added auto file name generation to image generating filters
-  (latex,music, graphviz).
-- Added `counter2` and `set2` system attributes (to implement image
-  auto file name generation).
-- Undefined attribute in filter command generates error but does not
-  exit.
-- Attribute substitution proceeds from start line to end line
-  (previously was in reverse order which was really confusing).
-- Tidied up music filter code:
-  * Format option is optional and default to 'abc' unless Lilypond
-    notation detected.
-  * The -m option does not apply to stdin input.
-- Added paragraph styles to music and graphviz filters.
-- Documented dynamic template names.  753: Graphviz filter can now
-  generate SVG format images. Patch submitted by Elmo Todurov, see:
-  http://groups.google.com/group/asciidoc/browse_frm/thread/fe9b33d8f5f1e0af
-  The xhtml11 SVG Graphviz template marked EXPERIMENTAL. No SVG
-  support for other backends.
-- AsciiDoc template names can now contain embedded attribute
-  references.
-- Added 'legalnotice' tag to `doc/article-docinfo.xml` example.
-- xhtml11 backend: Callouts and callout lists display callout icons
-  when the 'icons' attribute is defined. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/8eda3ea812968854
-- Document attribute names are case insensitive everywhere, this makes using
-attribute entries more consistent e.g. previously :VERS: had to be referred to
-with {vers} ({VERS} did not work).
-- Hungarian translation of footer-text (submitted by Miklos Vajna).
-  See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72#
-- asciidocapi.py 0.1.2: Can now load AsciiDoc script named asciidoc.
-  See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/66e7b59d12cd2f91
-  Based on patch submitted by Phillip Lord.
-- German translation of footer-text (submitted by Simon Ruderich). See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72
-- Pushed HTML footer text into language conf files with the
-  introduction of a footer-text configuration file template section.
-  See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72
-
-.Bug fixes

-  paragraph were mistakenly seen as starting with an inline literal.
-  See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/219c86ae25b79a21
-- *FIXED*: 'localtime' and 'doctime' attributes calculated incorrect
-  daylight saving / non daylight saving timezones and consequently so
-  did HTML footers.  Patch submitted by Slawomir Testowy. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/af652507caf6cec9
-- *FIXED*: Missing selector for 'List of examples' title in DocBook

-- *FIXED*: Broken accents in lang-hu.conf. See:
-  http://groups.google.com/group/asciidoc/browse_frm/thread/7174cb7598993c72
-- *FIXED*: DocBook XSL generated HTML callout lists are properly
-  aligned.  Submitted by Lionel Orry. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/2ff802547b6a75ea
-- *FIXED*: Filter execution now occurs prior to filter markup template
-  substitution to ensure image data URI encoding happens after image
-  generation (see
-  http://groups.google.com/group/asciidoc/browse_thread/thread/14e8fcb289a135b).
-- *FIXED*: The section numbers no longer increment when the 'numbered'
-  attribute is undefined (see
-  http://groups.google.com/group/asciidoc/browse_thread/thread/faa36e9e5c7da019/d24cab3fe363e58d).

-  DBLATEX_OPTS, FOP_OPTS, XSLTPROC_OPTS (appended to same-named
-  command-line options). See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/ac4b9bfa2116db28

-- Added `./tests/data/lang-pt-BR-test.txt` file to the repository.
-- xhtml11: Verse block and verse paragraph content enveloped in a
-  'pre' tag (instead of a 'div') so it renders better in text-only
-  browsers. See:

-
-Regression issues
-~~~~~~~~~~~~~~~~~
-There's been quite a bit of tiding up to the xhtml11 JavaScript. The
-most obvious change is that the toc.js script has been superceded by
-asciidoc-xhtml11.js so if you're linking you'll need get a copy of
-the new file from the distribution javascripts directory.
-
-If you use customised xhtml11 configuration file `header` and
-`footer` sections and you want them to use the new footnotes feature
-then you've got a bit more work to do:
-
-. The onload event expression changed.
-. The new `<div id="content">...</div>` div envelopes document
-  content.
-. You need to add `<div id="footnotes">...</div>` div to the
-  `footnotes` section for footnotes to work.
-. Drop the `ifdef::toc` macro that surround JavaScript inclusion.
-
-Take a look at the header and footer changes in the xhtml11.conf
-diff to see what's going on:

-Version 8.5.0 (2009-10-04)
---------------------------
-.Additions and changes
-- Implemented a 'float' attribute for tables and block images (HTML
-  outputs only).
-- Added `unfloat::` block macro to cancel floating.
-- Added table 'align' attribute to (HTML outputs only).
-- The image 'align' attribute now works with HTML backends.

-  with the new table 'align' attribute.
-- Added 'breakable' and 'unbreakable' options to AsciiDoc example and
-  block image elements.
-- `miscellaneous` section entries now update properly when set from
-  a document 'AttributeEntry'.
-- `miscellaneous` section `pagewidth` entry accepts fractional
-  values.
-- Fractional column widths are now calculated correctly when using
-  fractional 'pageunits' (DocBook tables).
-- Use DocBook XSL table width processing instructions.
-- asciidoc 'KeyboardInterrupt' exits with error code 1.
-- Added 'set' system attribute to  allow attributes to be set from
-  configuration file templates.
-- Allow constrained quotes to be bounded on the left by a colons and
-  semicolons, see
-  http://groups.google.com/group/asciidoc/browse_frm/thread/b276a927fdc87995
-- Titled listing and literal blocks (DocBook outputs) no longer default
-  to examples. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/f4df7c9eec01a9bd
-- Updated language file table, figure and example captions to
-  accommodate new auto-numbering in html4 and xhtml11 backends.
-- Titled source highlight filter listings generated by docbook backend
-  are now rendered as examples. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/f4df7c9eec01a9bd
-- Implemented 'counter' system attribute.
-- Use 'counter' system attributes to number titled tables and block
-  images in HTML backends.

-  http://groups.google.com/group/asciidoc/browse_frm/thread/d29924043e21cb6a.
-- Added 'max-width' attribute to the 'xhtml11' backend to set maximum
-  display width. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/74d9a542b79ccd50.
-- Added 'a2x.py', a rewritten and much enhanced version of the old
-  'a2x' bash script.
-- The new 'a2x' can output EPUB formatted documents.
-- Added `--safe` option and deprecated `--unsafe` option. Patch
-  submitted by Todd Zullinger. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/ea3a8ea399ae5d2a
-  and
-  http://groups.google.com/group/asciidoc/browse_frm/thread/69b3183fdab7c6a5
-- Added 'CHECK' and 'TEST' todo highlight words to Vim syntax
-  highlighter.
-- Line breaks, page breaks, and horizontal rulers are now processed by
-  dblatex, thanks to a patch submitted by Mark Fernandes
-  (http://groups.google.com/group/asciidoc/browse_frm/thread/a254cf949ea7c6c5).
-- Allow footnote macros hard up against the preceding word so the
-  rendered footnote mark can be placed against the noted text without
-  an intervening space (patch submitted by Stas Bushuev,
-  http://groups.google.com/group/asciidoc/browse_frm/thread/e1dcb7ee0efc17b5).
-- Normalized path in `safe_filename` function (submitted by Todd
-  Zullinger,
-  http://groups.google.com/group/asciidoc/browse_frm/thread/69b3183fdab7c6a5).
-- The Asciidoc 'numbered' and 'toc' attributes cause DocBook outputs
-  to include `asciidoc-numbered` and `asciidoc-toc` processing
-  instructions, these are used by DocBook XSL to include section
-  numbering and table of contents (like Asciidoc HTML backends). For
-  backward compatibility both 'numbered' and 'toc' attributes are
-  defined by default when the 'docbook' backend is used.  See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/1badad21ff9447ac.
-- 'data-uri' attribute is now evaluated dynamically and can be set in
-  document body (previously could only be set from command-line).
-- Added 'sys3' and 'eval3' system attributes to passthrough generated
-  output, this fixes the data-uri inline image problem:
-  http://groups.google.com/group/asciidoc/browse_frm/thread/a42db6bc54c2c537.
-- Missing language file generates a warning instead of an error.
-- Updated Spanish language file (updates contributed by Gustavo Andrés
-  Gómez Farhat).
-
-.Bug fixes
-- *FIXED:* Options in an 'AttributeList' option attribute are merged
-  with (rather than replace) configuration file options.
-- *FIXED:* Comment blocks and comment block macros no longer consume
-  preceding block titles and attribute lists.
-- *FIXED:* `examples/website/layout1.conf` and
-  `examples/website/layout2.conf` TOC problem.  Submitted by Mark
-  (burtoogle).  See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/b9c63be67dd1d11c
-- *FIXED:* Only the first occurrence of passthrough macro was
-  substituted.  Patch submitted by  Peter Johnson. See
-  http://groups.google.com/group/asciidoc/browse_frm/thread/1269dc2feb1a482c
-- *FIXED:* asciidoc now runs on Jython 2.5.0.
-- *FIXED:* Wordpress margins and pads in a number of block
-  elements
-  (http://groups.google.com/group/asciidoc/browse_frm/thread/36ff073c79cbc20a).
-
-Regression issues
-~~~~~~~~~~~~~~~~~
-- Tables generated by 'dblatex' occupy 100% of the available space
-  regardless of the 'width' attribute setting. To restore width
-  behavior change the 'pageunits' miscellaneous parameter to 'pt'. You
-  can do this from the command-line with the `-a pageunits=pt` option.
-  See {website}userguide.html#X89DocBook table widths.

-
-Version 8.4.5 (2009-05-24)
---------------------------
-.Additions and changes
-- Added manpage 'Name' and 'Synopsis' section title customization to languages
-  configuration files.
-- Synopsis manpage section no longer mandatory.
-- Section markup templates can be specified by setting the title's
-  first positional attribute or 'template' attribute.
-- The article and book document header can now include a revision
-  remark.
-- A 'role' attribute can now be applied to block elements. This adds
-  the 'role' attribute to DocBook elements. Patch submitted by
-  http://groups.google.com/group/asciidoc/browse_thread/thread/62278a054188a038Noah
-  Slater).
-- Renamed 'revision' and 'date' attributes to more sensible and consistent
-  'revnumber' and 'revdate' (old names deprecated but still
-  recognized).
-- Moved backend specific attributes to Appendix H in User Guide.
-- Renamed and generalized the docbook backend revision history
-  inclusion mechanism to 'docinfo' to reflect the use of all article
-  or book information elements. The old revision history names still
-  work but have been deprecated.
-- Refactored docbook.conf headers.
-- Moved line break replacement from `replacements` to
-  `replacements2` so the replacement occurs after the mailto macro.
-  This fixes bug
-  http://groups.google.com/group/asciidoc/browse_thread/thread/4bdcdfb0af773e2
-- The typewriter to punctuation apostrophe replacement can be escaped
-  with a backslash.
-- Graphviz filter outputs images to 'imagesdir' if it is defined.
-- Made the block image macro generic so that it can be used for filter
-  outputs. As a result Music and Graphviz filters:
-  * Have been greatly simplified.
-  * Honor the 'data-uri' attribute.
-  * 'html4' outputs no longer generate W3C validation warning.
-- The 'iconsdir' attribute no longer requires a trailing directory
-  separator character.
-- Removed borders around linked html4 images.
-- Added 'html4' specific HTML output for music filter.
-- 'a2x': Added `--unsafe` option (shortcut for
-  `--asciidoc-opts=--unsafe`).
-- 'a2x': The FOP executable can now be named `fop` (this is the
-  default name in some distributions).
-- Attributes are now substituted in the system macro attribute list.
-- If the output is set to stdout (i.e. no output directory is defined)
-  then Music and Graphviz filters will output included images to the
-  source file directory.
-- Added 'name' directive to 'testasciidoc'.
-- Added lots of 'testasciidoc' new tests.
-- Moved language specific configuration parameters into `lang-en.conf`
-  file.
-- 'lang' attribute entry can be specified in the AsciiDoc source file
-  (preceding the header).
-- Removed cruft from A-A-P scripts and documented them.
-- Added German language config file (`lang-de.conf`) contributed by
-  Michael Wild.
-- Added French language config file (`lang-fr.conf`) contributed by
-  Yves-Alexis Perez.
-- Added Russian language config file (`lang-ru.conf`) contributed by
-  Artem Zolochevskiy.
-- Added Hungarian language config file (`lang-hu.conf`) contributed by
-  Miklos Vajna.
-
-.Bug fixes
-- *FIXED:* Multiple manpage names are now handled correctly when
-  generating DocBook output, each name now generates a separate
-  DocBook `<refname>` element. See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/c93bb4db025225d8
-- *FIXED:* A problem that caused AttributeEntries preceding the header
-  to be overwritten when the language conf file loaded.
-- *FIXED:* Possible inline macro name ambiguity e.g. link matches olink.
-- *FIXED:* The documented macro definition deletion behavior had been
-  broken for a long time.
-- *FIXED:* Email addresses not recognized when followed by a period
-  character.
-- *FIXED:* Hyphens in mailto macros can delimit nested addresses e.g.
-  \bloggs@mail was processed inside
-  \mailto:joe-bloggs@mail-server.comMail.
-- *FIXED:* User name in FTP URI generated incorrect FTP link. See
-  http://groups.google.com/group/asciidoc/browse_thread/thread/1d796a9c9ddb2855
-- *FIXED:* Source highlighter now works with Wordpress backend (see
-  http://groups.google.com/group/asciidoc/browse_thread/thread/6d8c716748b109e3).
-
-X2
-Regression issues
-~~~~~~~~~~~~~~~~~
-. A colon following the date in the AsciiDoc header is treated as a
-  revision remark delimiter -- this could be an issue if you have used
-  a colon in the header date.
-
-
-Version 8.4.4 (2009-04-26)
---------------------------
-.Additions and changes
-- Added table column and row spanning.
-- Table styles can now be applied per cell.
-- Vertical cell alignment can be applied to columns and individual
-  cells.
-- Added table 'align' attribute to set horizontal alignment for entire
-  table.
-- Included Geoff Eddy's update of the experimental LaTeX backend.
-- A new attribute named 'trace' controls the output of diagnostic
-  information. If the 'trace' attribute is defined then
-  element-by-element diagnostic messages detailing output markup
-  generation are printed to stderr.
-- Added 'literal' paragraph style (allows 'literal' style to be
-  applied to normal paragraphs).
-- Deleted unused `replacements2` from `xhtml11.conf`.
-- Added `replacements2` to default substitutions.
-- 'testasciidoc.py': messages to 'stdout', only diffs to 'stderr'.
-- Added transparency to `smallnew.png` image.
-
-.Bug fixes
-- All combinations of leading comments and attribute entries at the
-  start of a document are now skipped correctly.
-- *FIXED:* `./configure` doesn't support `--docdir` as expected (patch
-  submitted by Artem Zolochevskiy)
-- *FIXED:* Constrained quotes were incorrectly matched across line
-  boundaries e.g. the string `+\nabc+` incorrectly matched a monospace
-  quote.
-
-
-Version 8.4.3 (2009-04-13)
---------------------------
-.Additions and changes
-- DocBook outputs default to DocBook version 4.5 doctype (previously
-  4.2).
-- Configuration file `specialsections` definitions can be undefined
-  by setting their configuration entry values blank.
-- The Makefile 'install' target depends on the 'all' target to ensure
-  pre-install patches are applied.
-- 'testasciidoc.py' now emits user friendly messages if:
-  . the configuration file is missing.
-  . an illegal backend is specified.
-  . an illegal test number is specified.
-
-.Bug fixes
-- Fixed
-  http://groups.google.com/group/asciidoc/browse_thread/thread/fd27add515597c06missing
-  template section error.
-- The 'testasciidoc.py' `--force` option no longer deletes test data
-  files that were not specified.
-- Dropped second quotes substitution in table cells -- it had
-  effectively disabled quote escaping in table cells.
-
-
-Version 8.4.2 (2009-03-19)
---------------------------
-.Additions and changes
-- Added {website}testasciidoc.htmltestasciidoc, a tool to verify
-  AsciiDoc conformance.
-- A warning is issued if nested inline passthroughs are encountered.
-- 'asciidocapi': setting an attribute value to `None` will undefine
-  (delete) the attribute (this in addition to the `name!` attribute
-  name format that the `asciidoc(1)` command uses).
-
-.Bug fixes
-
-
-Version 8.4.1 (2009-03-10)
---------------------------
-.Additions and changes
-- AsciiDoc now has a {website}asciidocapi.htmlPython API.  The
-  following minimal example compiles `mydoc.txt` to `mydoc.html`:
-+
-source,python
--------------------------------------------------------------------------------
-from asciidocapi import AsciiDocAPI asciidoc = AsciiDocAPI()
-asciidoc.execute('mydoc.txt')
--------------------------------------------------------------------------------
-
-- Backtick quoting for monospaced text is now implemented as an
-  'inline literal' passthrough.  This makes more sense since monospace
-  text is usually intended to be rendered literally. See
-  <<X2,Regression issues>> below for the impact this may have on
-  existing documents.  Here are some examples that would previously
-  have had to be escaped:
-
-  The `++i` and `++j` auto-increments.
-  Paths `~/.vim` and `~/docs`.
-  The `__init__` method.
-  The `{id}` attribute.
-
-- Added `--doctest` option to `asciidoc(1)` command.
-- Added an optional second argument to 'BlockId' element, this sets
-  the `{reftext}` attribute which in turn is used to set the `xreflabel`
-  attribute in DocBook elements.
-- Added lists to `--help` syntax summary.
-- `{infile}` and `{indir}` attributes reflect the current input file
-  (previously always referred to the root document).
-- `{docfile}` (new) and `{docdir}` (previously deprecated) attributes
-  refer to the root document specified on the `asciidoc(1)`
-  command-line.
-- Vim syntax highlighter improvements.
-- Syntax summary command (`asciidoc -h syntax`) additions.
-- Admonition icons now have transparent backgrounds.
-- Changed yellow W3C badges to blue ones in page footers.
-
-.Bug fixes
-- Dropped `asciidoc(1)` broken undocumented `--profile` option.
-- Em dash replacement now recognized at start of block.
-
-Regression issues
-~~~~~~~~~~~~~~~~~
-Replacing backtick quoting with the 'inline literal' passthrough
-raises two regression scenarios for existing documents:
-
-1. You have escaped the expansion of enclosed inline elements, for
-   example: `\{id}`.  You would need to delete the backslashes: `{id}`
-   (if you don't the backslashes will be printed). Mostly it's just a
-   case of interactively finding and replacing of all occurrences of
-   `\.
-
-2. There are enclosed inline elements, for example: `some *bold*
-   monospaced`.  You would need to switch to plus character monospace
-   quoting: `+some *bold* monospaced+` (if you don't the enclosed
-   elements won't be expanded).
-
-If your existing documents include these cases and you don't want to
-upgrade then use the `-a no-inline-literal` command-line option,
-alternatively put this in `~/.asciidoc/asciidoc.conf`:
-
-  attributes
-  no-inline-literal=
-
-
-Version 8.3.5 (2009-02-02)
---------------------------
-.Additions and changes
-- Cached compiled regular expression delimiters (speed up 'User
-  Manual' compilation by 250%).
-- Created distinct list definitions for each numbered list style to
-  allow nesting of all styles.
-- Roman numbers in numbered lists are followed by a closing
-  parenthesis instead of a period to eliminate 'i', 'v', 'x' item
-  ambiguity with respect to alpha numbered list items.
-- Added `**`, `***`, `****`, `*****`
-  bulleted lists.
-- Added `...`, `....`, `.....` implicit numbered
-  lists.
-- Added `:::`, `::::` labeled lists.
-- Updated User Guide for new list syntaxes.
-- Optimized paragraph and list termination detection with separate
-  precompiled regular expressions for performance and to prevent
-  reaching Python 100 named group limit.
-- Updated Vim syntax highlighter for new list syntaxes.
-- Allow `template::` macros in conf file entries sections (not just
-  in template sections).
-- Dropped unused `listdef-numbered2` conf file sections.
-- Renamed 'ListBlock' to more appropriate 'OpenBlock'.
-- Implemented single-line versions of `ifdef::` and `ifndef::`
-  macros.
-- 'html4' backend styling:
-  * Underlined admonition captions.
-  * Added side border to Example Blocks.
-- 'xhtml11' backend styling:
-  * Dropped right hand margin from all but quote and verse blocks.
-  * html4 backend: corrected over-sized width of caption in admonition
-    block.
-
-.Bug fixes
-- Fixed broken numbered list nesting.
-
-Compatibility issues
-~~~~~~~~~~~~~~~~~~~~
-The roman numbered list parenthesis syntax is incompatible with the
-potentially ambiguous roman period syntax introduced in 8.3.2.
-
-
-Version 8.3.4 (2009-01-20)
---------------------------
-.Additions and changes
-- Implemented a title 'float' style.  A floating title (or bridgehead)
-  is rendered just like a normal section but is not formally
-  associated with a text body and is not part of the regular section
-  hierarchy so the normal ordering rules do not apply.
-- Implemented inline comment macro so comment lines can now appear
-  inside block elements.
-- Comment lines are sent to the output if the 'showcomments' attribute
-  is defined (comment blocks are never sent to the output).
-- Single quoting attribute values in 'AttributeList' elements causes
-  them to be substituted like normal inline text (without single
-  quoting only attribute substitution is performed).
-- Rewrote list item processing (was very crufty). List continuation
-  and list blocks now work as expected. Updated and clarified list
-  documentation in User Guide.
-- The 'revision' attribute now recognizes the RCS $Id$ marker format.
-- An RCS $Id$ marker formatted revision line in the header does not
-  need to be preceded by an author line.
-- If an RCS $Id$ formatted revision is specified and the author name
-  has not already been set then the author name in the $Id$ marker
-  will be used.
-- Updated Gouichi Iisaka's Graphviz filter to version 1.1.3.
-- Added 'autowidth' table attribute option for (X)HTML outputs.
-- DocBook backend now puts 'orgname' optional attribute in DocBook
-  header.
-- Deprecated undocumented 'companyname' attribute in favor of
-  DocBook's 'corpname'.
-- Removed explicit closing backslash from HTML4 self-closing tags to
-  comply with WC3 recommendation.
-
-.Bug fixes
-- Fixed 8.3.3 regression whereby adjacent lists with the same syntax
-  but different list styles were incorrectly treated as a single list.
-
-
-Version 8.3.3 (2009-01-02)
---------------------------
-This release supersedes 8.3.2.
-
-.Bug fixes
-- The broken and confusing numeration and numeration2 numbered list
-  attributes have been dropped, use the style attribute instead.
-
-
-Version 8.3.2 (2009-01-01)
---------------------------
-.Additions and changes
-- Added Gouichi Iisaka's Graphviz filter to distribution.
-- The 'SidebarBlock' element can now be rendered with an 'abstract'
-  style.
-- Reorganized filters into a separate subdirectory for each filter.
-- Updated `Makefile.in` and `MANIFEST` files to reflect new filters
-  organization.
-- Added 'listing' style to 'LiteralBlock' element so listings with
-  nested listing blocks can be rendered as a listing block.
-- Changed example 'code' filter to use preferred 'ListingBlock' syntax
-  (the old `~` delimited filter syntax is no longer used).
-- Implemented 'enumeration' and 'enumeration2' numbered list
-  attributes for specifying the list numbering style ('arabic',
-  'loweralpha', 'upperalpha', 'lowerroman' and 'upperroman').
-- AsciiDoc now recognizes 'upperalpha', 'lowerroman' and 'upperroman'
-  numbers in `listdef-numbered2` numbered lists and sets the number
-  style based on the style of the first numbered list item
-  (alternative to setting 'enumeration2' attribute).
-- Updated `formatlistpat` definition in `.vimrc` example in User
-  Guide.
-- You can now backslash escape system block macros.
-- Added 'Pychart' FAQ.
-- Drop paragraph 'text' and list 'text', 'index' and 'label' match
-  groups from attributes -- they are included in the element's text
-  and we don't want them processed a second time as attributes.
-- Changed comment line block macro to a passthrough block macro to
-  ensure no substitutions.
-- A 'subslist' no longer has to be appended to a 'PassthroughBlock'
-  macro definition, if omitted no substitutions are performed.
-- Code tidy up: replaced deprecated `<>` operator with `!=`.
-- Removed unused linuxdoc code.
-- Code tidy ups: dropped old types module reference; replaced
-  `has_key()` with preferred `in` operator.
-
-.Bug fixes
-- Old syntax source highlight filter regression: special characters
-  where not escaped in DocBook outputs.
-
-
-Version 8.3.1 (2008-12-14)
---------------------------
-.Additions and changes
-- Replaced the `install.sh` script with Ben Walton's updated autoconf
-  scripts -- see {website}INSTALL.htmlINSTALL for details.
-- Added a generalized 'AttributeEntry' syntax to allow arbitrary
-  configuration file entries to be set from within an AsciiDoc
-  document (suggested by Henrik Maier).
-- Listing delimited blocks in DocBook outputs now support IDs; IDs of
-  titled Listing and Literal delimited blocks have been moved to the
-  enclosing DocBook example tag (thanks to Vijay Kumar for this
-  patch).
-- Replaced vertical typewriter apostrophe with punctuation apostrophe
-  (thanks to Noah Slater).
-
-.Bug fixes
-- Regression: Excluding double-quotes from unquoted attribute values
-  resulted in backward incompatibility, double-quotes in unquoted
-  attribute values has been reinstated.
-- Regression: Text like `&...;` was sometimes mistaken for an entity
-  reference -- tightened up entity reference matching.
-
-
-Version 8.3.0 (2008-11-29)
---------------------------
-.Additions and changes
-- {website}newtables.htmlAsciiDoc new tables is a complete redesign
-  of the tables syntax and generation. The new syntax and features are
-  a huge improvement over the old tables. The old tables syntax has
-  been deprecated but is currently still processed.
-- {website}newlists.htmlLists can now be styled like other block
-  elements. This allows a single list syntax for 'glossary', 'qanda'
-  (Question and Answer) and 'bibliography' lists instead of having to
-  remember a different syntax for each type.
-- Inline passthroughs macros have been improved and block passthrough
-  macros added. Attribute substitution can be optionally specified
-  when the macro is called.
-- The passthrough block has a fully transparent passthrough delimited
-  block block style called 'pass'.
-- The 'asciimath' and 'latexmath'
-  {website}userguide.html#X77passthrough macros along with
-  'asciimath' and 'latexmath' {website}userguide.html#X76passthrough
-  blocks provide a (backend dependent) mechanism for rendering
-  mathematical formulas. There are {website}latexmath.pdfLaTeX Math,
-  {website}asciimathml.htmlAsciiMathML and
-  {website}latexmathml.htmlLaTeXMathML examples on the AsciiDoc
-  website.
-- Reimplemented and cleaned up filter processing based on a patch
-  submitted by Kelly Anderson.  Uses the newer subprocess module
-  instead of the deprecated popen2 module.  Now works in Win32 command
-  shell.
-- Addition FAQs, more documentation updates.
-- Arbitrary HTML/XML entities can be entered in AsciiDoc source.
-- Did away with the need for the `shaded-literallayout.patch` (thanks
-  to Henrik Maier for this patch).
-- Implemented 'page break' block macro.
-- Added 'line breaks' and 'ruler' processing instructions to DocBook
-  outputs  (thanks to Henrik Maier for this patch).
-- Added 'deg' (degree) and 'wj' (word joiner) entity attributes
-  (thanks to Henrik Maier).
-- Tweaked DocBook 'indexterm2' macro to avoid white space preceding
-  the term when used in table cells (thanks to Henrik Maier for this
-  patch).
-- Title elements now process the 'options' attribute like other block
-  elements.
-- Added `single quoted' element.
-- Spaces on both sides of a -- em-dash are translated to thin space
-  characters.
-- Improved detection and reporting of malformed attribute lists.
-- The list 'compact' style is now a list option.
-- Added 'strong' labeled list option which makes the labels bold (HTML
-  outputs only).
-- Dropped unsupported 'linuxdoc' backend.
-- Dropped deprecated 'xhtml-deprecated' (version 6) backend.
-- Added 'breakable' and 'unbreakable' attribute options to tables to
-  control table breaking across page boundaries (DocBook XSL/FO
-  outputs). By and in collaboration with Henrik Maier.
-- Added 'pgwide' attribute option to tables to table, block image,
-  horizontal labeled lists.  Specifies that the element should be
-  rendered across the full text width of the page irrespective of the
-  current indentation (DocBook XSL/FO outputs). Thanks to Henrik Maier
-  for this patch.
-- Vim syntax highlighter: spaces before/after bullets no longer
-  highlighted (which is ugly if using a theme that highlights with
-  underlines).  Thanks to Donald Chai for this patch.
-- Added `a2x(1)` `--fop` option.
-- Added `a2x(1)` `--no-xmllint` option.
-- Highlighted labelled list terms with the navy color in XHTML
-  outputs.
-- Use `w3m(1)` as default `a2x(1)` text format generator (fallback to
-  `lynx(1)`).
-- Changed callout formats in html4 and xhtml11 outputs to angle
-  brackets to match source highlighter rendering.
-- Macros now inject user defined `<optionname>-option` attributes into
-  markup.
-- Added IRC URLs to AsciiDoc inline macros.
-- Added `depth` attribute to `include::` system macro.
-- Added 'footnoteref' inline macro.
-- Added 'stylesheet' XHTML attribute to specify additional custom CSS
-  stylesheet.
-- If a paragraph style is specified it will be added to the XHTML
-  'class' attribute and DocBook 'role' attribute.
-- Replacements can be set in a document using the reserved
-  AttributeEntry name 'replacement'.
-- The prefix for auto-generated section name IDs can be set with the
-  'idprefix' attribute.

-- Escaped quote skipped over leading and trailing quote instead of
-  just the leading quote.
-- Fixed bug that was causing false negative safe mode warnings (patch
-  submitted by Julien Palmas).
-- Placed priority of AttributeEntry, AttributeList and BlockTitle
-  above Title.  This ensures an  AttributeEntry, AttributeList or
-  BlockTitle followed by a same length leading ListingBlock delimiter
-  is not mistaken for a two-line title.
-- Vim syntax highlighter: fixed multi-line quoted text.
-- Contstrained quote termination after non-space character enforced.
-- Vim syntax highlighter: unterminated quoted text is no longer
-  highlighted.
-- Vim syntax highlighter: passthroughs now exactly match AsciiDoc
-  semantics.
-- Vim syntax highlighter: escaped quoted text, attribute references
-  and inline macros are not highlighted.
-- Vim syntax highlighter: TODO's highlighted in CommentBlocks (thanks
-  to Scott Wall); non-greedy pass:$$...$$.
-- Vim syntax highlighter: Comment lines mistaken for vertical list
-  labels (thanks to Scott Wall).
-- Vim syntax highlighter: Single unmatched $$ mistakenly highlighted
-  remaining text (patch contributed by Scott Wall).
-- Callouts now work in source highlighted listing generated by
-  dblatex.
-- Fixed exception that occurred if undefined attribute was present in
-  filter command.
-- AttributeList block can now follow a paragraph without intervening
-  blank line.
-- The include macro tabsize attribute is no longer propagated to
-  nested includes.
-
-.Omissions
-The following features were implemented but then but removed from this
-release:
-
-- 'pi', 'cdata' and 'comment' passthrough macros and passthrough block
-  styles (creeping featurism, use 'pass' macros instead).
-- Generic 'tag' inline macro (creeping featurism, use 'pass' macros
-  instead).

-Compatibility issues
-~~~~~~~~~~~~~~~~~~~~
-Version 8.3.0 has a number of backward incompatibilities with respect
-to the previous 8.2.7 release:
-
-- The old table syntax is still processed but a 'DEPRECATED' warning
-  is issued.
-- Entity references have to be escaped with a backslash.
-- You have to explicitly precede horizontal style labeled lists with
-  the `horizontal` style attribute -- by default all labeled lists
-  are rendered vertically.
-- The list 'compact' style has been dropped and is now a list option
-  (use `options="compact"` in attribute lists).
-- AsciiDoc version 6 sytnax no longer supported.
-- Linuxdoc been removed from the distribution.
-- The unsupported experimental 'latex' backend has not been tested on
-  this release.
-- The introduction of single-quote quoting requires that double-quote
-  quoting is escaped with two backslashes.
-
-
-Version 8.2.7 (2008-07-04)
---------------------------
-.Additions and changes
-- Added `dvi`, `ps` and `tex` output format options to a2x(1).
-- Added `--dblatex` option to a2x(1) so `dblatex(1)` can be used to
-  generate PDFs.
-- Added custom `dblatex(1)` configuration files (in distribution
-  `./dblatex` directory) that are used by a2x(1).
-- `dblatex(1)` is now used to generate the distributed PDF version of
-  the AsciiDoc User Guide.
-- If you don't need a customized the link caption you can enter the
-  'http', 'https', 'ftp', 'file' URLs and email addresses without any
-  special macro syntax -- you get the links by just cutting and
-  pasting URLs and emails addresses. This also makes it easier to open
-  links directly form AsciiDoc source ( most editors allow you to open
-  URLs directly).  The Vim syntax highlighter has been updated to
-  reflect these changes.
-- Highlighted source code paragraphs have been implemented -- it's a
-  much more convenient way to enter short code examples (see
-  http://asciidoc.org/source-highlight-filter.htmlthe
-  online docs).
-- The source highlighter and music filter syntax has changed -- they
-  now used the ListingBlock syntax customized with 'source' and
-  'music' style attribute values. This follows the Paragraph styling
-  convention introduced by the source paragraph (previous item) and is
-  easier to read. The old syntax still works but has been deprecated.
-- QuoteBlocks now have a 'verse' style -- you no longer have to nest a
-  'verse' LiteralBlock inside a QuoteBlock for verses.  The 'verse'
-  style on the LiteralBlock has been deprecated (still works though)
-  and the 'style' attribute is positional attribute 1, pushing
-  'attribution' and 'citetitle' attributes to the right (you'll need
-  to insert a 'quote' attribute into your existing QuoteBlocks).
-- It is no up to the DocBook processor to highlight source code syntax
-  in `<programlisting>` elements rather than GNU Highlighter -- this
-  is the correct way to handle it, plus `dblatex(1)` makes a much
-  better job.
-- 'scaledwidth' and 'align' attributes have been added to the 'image'
-  macro. They apply to DocBook outputs (specifically for PDF
-  documents). 'scaledwidth' sets the image size as a percent of the
-  available page width; 'align' applies 'left', 'center' or 'right'
-  horizontal image justification.
-- Added a2x(1) `--fop-opts=FOP_OPTS` option (patch submitted by Miklos
-  Vajna).
-- Added a2x(1) `--dblatex-opts=DBLATEX_OPTS` option.
-- Added Mikhail Yakshin's FOP 0.95 patch which fixes a long-standing
-  `fo.xsl` problem and allows PDF's to be generated with FOP 0.95
-  (previously had to use FOP 0.20.5).
-- The User Guide has been updated and outdated FOP configuration and
-  installation sections removed.
-
-.Bug fixes
-- Fixed `stylesheets/xhtml11-manpage.css` not being included when
-  'linkcss' attribute was used.
-- Configuration file `*-style` attributes are now dumped correctly.
-- Fixed 'FAILED: malformed section entry' LaTeX backend error.
-
-See the also the https://sharesource.org/hg/asciidoc/AsciiDoc
-repository changelog.
-
-
-Version 8.2.6 (2008-04-29)
---------------------------
-.Additions and changes
-- Enhancements to the Vim AsciiDoc syntax highlighter, for example,
-  quoted text is now highlighted in titles and macro captions.
-- If you define the `data-uri` intrinsic attribute images referenced
-  by 'image' macros will be embedded in XHTML using the
-  http://en.wikipedia.org/wiki/Data:_URI_schemedata: URI scheme.
-  *NOTE*: Microsoft browser support for the 'data: URI scheme' is
-  currently limited to MSIE 8 beta 1.
-- Added `toc-title` attribute to allow custom table of contents
-  titles.
-- Added references to Alex Efros's AsciiDoc Cheatsheet to AsciiDoc
-  website.
-- `asciidoc(1)` and `a2x(1)` man pages formatted to conform to
-  `man-pages(7)` recommendations.
-- Old code-filter syntax (pre-8.1.0) is no longer recognized so that
-  malformed two-line level 2 titles are no longer confused with
-  'code-filter' block delimiters.
-- Added -> <- => <= arrow replacements from the Arrows block of
-  Unicode.
-- Added DocBook refentry lang attribute -- patch contributed by
-  VMiklos.
-- AttributeEntry names can now be numeric (``named macro targets'').
-- Hide Table of Contents title if Table of Contents empty -- patch
-  contributed by Alex Efros.
-- Various XHTML CSS tweaks.
-- Code cleanup:
-  * Replaced `realpath()` with Python 2.2 `os.path.realpath()` library
-    function.
-  * Replaced old string library functions with string methods.
-  * Use file generators instead of `readlines()`.
-  * Renamed entities that shadowed builtins.
-  * Standardized string quoting.
-  * Dropped `readlines()` function.
-
-.Bug fixes
-- Fixed broken CSS for decimal ordered lists nested in alpha ordered
-  list, thanks to Alex Efros.
-- A missing closing block delimiter now reports the opening delimiter
-  line number instead of the end of file line number.
-- Fixed an error generated by the asciidoc `-e` option when there are
-  no block definitions -- patch contributed by Alejandro Mery.
-- Handle both `\r\n` (as well as `\n`) line separators that may be
-  returned by `{sys}` attribute evaluation.
-- Numbered attribute names no longer interfere with positional
-  attribute list values.
-
-
-Version 8.2.5 (2007-11-18)
---------------------------
-.Additions and changes
-
-.Bug fixes
-- Fixed exception thrown by illegal command-line arguments.
-- Rolled back the 'with' warning bug fix introduced in 8.2.4 -- it was
-  incompatible with Python <2.5.
-
-
-Version 8.2.4 (2007-11-10)
---------------------------
-.Additions and changes
-- You can now use the `lang` attribute to set the DocBook language
-  attribute.
-- Attribute values can now contain attribute references.
-- If the `lang` attribute is defined then configuration files named
-  like `lang-<lang>.conf` will be loaded automatically.
-- The help file name `help-<lang>.conf` is based on the AsciiDoc
-  `lang` attribute, defaults to `help.conf` (English).
-- Admonition, figure and table captions have been factored into a
-  predefined set of `caption_*` attributes.  They only apply to
-  directly generated (X)HTML outputs (DocBook stylesheets generate
-  their own language specific captions based on the `lang` attribute).
-- Dropped platform dependent `doc/asciidoc.chm` file from
-  distribution documentation formats.
-
-.Bug fixes
-- The spurious warning 'with will become a reserved keyword
-  in Python 2.6' has been suppressed.
-
-
-Version 8.2.3 (2007-09-12)
---------------------------
-.Additions and changes
-- Added VMiklos's 'permalink' patch for auto-generated section IDs
-  (enabled by default by the `sectids` attribute).
-- Added http://asciidoc.org/faq.htmlFAQ to website.
-- Changed format of \{localdate} attribute to ISO 8601 (`%Y-%m-%d`).
-- Added `abc2ly --beams=None` option to make `music2png.py` conform to
-  ABC's notion of beams.
-- XHTML level 2 section headings are now styled with an underlining
-  border.
-- XHTML links to AsciiDoc title elements are now implemented with
-  title ID attributes (previously separate `<a>` element targets were
-  generated.
-- Multi-word first, middle and last names can be entered in the header
-  author line using the underscore as a word separator.
-- The nested inline macros restriction has now been lifted, for
-  example you can now include links and inline images inside
-  footnotes.
-- Help topic names can be shortened (so long as they are not
-  ambiguous). For example `asciidoc -hm` will print the AsciiDoc man
-  page.
-- Added `{two_colons}` and `{two_semicolons}` attributes for
-  escaping labeled list ambiguity.
-- If quirks mode is disabled the XHTML Mime Type is set to the
-  recommended `application/xhtml+xml` (rather than `text/html`).
-
-.Bug fixes
-- Author information is now correctly set when using attribute entries
-  in the header instead of an author line (previously the 'author'
-  attribute was not being calculated correctly and there were
-  attribute substitution problems).
-
-
-Version 8.2.2 (2007-07-22)
---------------------------
-.Additions and changes
-- http://www.maths.nottingham.ac.uk/personal/drw/lm.htmlLaTeXMathML
-  capability has been added for users who are more familiar with or
-  prefer LaTeX math formulas to the
-  http://asciidoc.org/asciimathml.htmlASCIIMathML
-  notation (thanks to Arthur Sakellariou for the patch).
-- The 'source highlight' and 'code' filters now process embedded
-  callouts.
-- Added an `--attribute=ATTRIBUTE` option to `a2x(1)` for passing
-  attribute values to asciidoc(1) (a shortcut for `--asciidoc-opts="-a
-  ATTRIBUTE"`).
-- Image block and inline macros prepend optional `{imagesdir}`
-  attribute to image link targets.
-
-
-.Bug fixes
-- Fixed an assertion error that occurred when a configuration file
-  containing an `include::` macro was loaded using the
-  `--conf-file` option and the configuration file name did not
-  include an explicit directory path -- patch submitted by Dmitry
-  Potapov.
-- Asciidoc titles are only converted to lower case if all characters
-  are upper case otherwise case is left unchanged -- patch submitted
-  by Dmitry Potapov.
-- Added a missing check that input is not stdin before loading
-  configuration files from the document directory -- patch submitted
-  by Dmitry Potapov.
-- Attribute list items must evaluate to strings, numbers or None
-  (previously it was possible to evaluate to other object types which
-  resulted in surprising attribute values).
-- If an AsciiDoc document has no title an empty XHTML 1.1 'title'
-  element is created -- previously the 'title' element was dropped
-  which resulted in invalid XHTML 1.1.
-- The Vim syntax file no longer highlights escaped callouts.
-- The Vim syntax highlighter now correctly highlights Double-dollar
-  passthroughs when they enclose dollar delimited ASCIIMathML and
-  LaTeXMathML formulas.
-
-
-Version 8.2.1 (2007-04-06)
---------------------------
-.Additions and changes
-- A number of improvements have been made to the Vim syntax
-  highlighter, for example the word C++ is no longer mistaken for the
-  start of an unconstrained monospace quote.
-- Labeled list definitions have been tightened -- a list label can no
-  longer containing trailing spaces. The following example is no
-  longer recognized as a valid list label:
-
-  Lorum ipsum ::
-+
-This change implements the originally intended behavior (as per the
-AsciiDoc documentation and examples) so there should be very few
-compatibility issues.
-
-.Bug fixes
-
-
-Version 8.2.0 (2007-04-04)
---------------------------
-.Additions and changes
-- A Vim syntax file is now included in the AsciiDoc distribution
-  (inspired by Felix Obenhuber's `asciidoc.vim` script). You can find
-  it (along with a Vim filetype detection script in the distribution
-  `./vim/` directory (the scripts are installed automatically by the
-  AsciiDoc installer `./install.sh`). See 'Appendix J' of the
-  'AsciiDoc User Guide' for details.
-- Added 'toclevel' attribute (1..4) which sets the number of title
-  levels reported in the table of contents.  Defaults to 2 and must be
-  used with the 'toc' attribute. Example usage:
-
-  $ asciidoc -a toc -a toclevels=3 doc/asciidoc.txt
-
-- Added a `listindex` attribute which is the current list item index
-  (1..). If this attribute appears outside a list its value is the
-  number of items in the most recently closed list.
-- The single line titles syntax now accepts trailing suffixes -- this
-  syntax matches the title line syntax of a number of popular Wiki
-  markups.
-- If a QuoteBlock has no attribution or citetitle then the DocBook
-  `<attribution>` element is not generated (previously generated empty
-  `<attribution>` element).
-- If the text of a labeled list item is blank then no `texttag` is
-  written.
-- An end of line backslash performs line continuation for horizontal
-  labeled list items.
-- The Revision line now accommodates Subversion `$Id` markers (in
-  addition to CVS and RCS markers). Thanks to Tiago Sturmer Daitx for
-  this patch.
-- Implemented `a2x(1)` option `--skip-asciidoc` which allows `a2x(1)`
-  to convert DocBook XML files not derived from AsciiDoc sources.
-- If `a2x(1) --doctype` option is not specified it defaults to
-  `manpage` if `--format=manpage` else defaults to `article`
-  (previously `--doctype` always defaulted to `article`).
-- Added an 'External Resources' section to the
-  http://asciidoc.org/index.htmlAsciiDoc home page.
-
-.Bug fixes
-
-
-Version 8.1.0 (2006-10-22)
---------------------------
-.Additions and changes
-- AsciiDoc generated XHTML documents now display a table of contents
-  if the 'toc' attribute is defined (JavaScript needs to be enabled
-  for this to work).  Thanks to Troy Hanson who contributed this
-  feature based on a JavaScript by Mihai Bazon. I've simplified things
-  somewhat to match Docbook XSL Stylesheets style, see Troy's
-  http://tpl.sourceforge.net/userguide.htmltpl User Guide for a
-  fancier layout. Use the `-a toc -a numbered` command-line options to
-  produce a number table of contents.
-- A http://asciidoc.org/music-filter.htmlmusic filter
-  is included in the distribution `./filters/` directory.  It
-  translates music in http://lilypond.org/LilyPond or
-  http://abcnotation.org.uk/ABC notation to standard classical
-  notation in the form of a trimmed PNG image which is inserted into
-  the AsciiDoc output document.
-- Incorporated Paul Melis's Win32 filter patch.  This workaround
-  allows AsciiDoc to run filters under Windows.
-- Added `uninstall.sh` script.
-- Rather than proliferate a confusing number of filter block
-  delimiters the following convention has been adopted: delimiters
-  belonging to DelimitedBlock filters distributed with AsciiDoc will
-  consist of a word (normally a noun identifying the block content)
-  followed by four or more tilde characters.  This has necessitated
-  changing existing filter delimiters (the old delimiters still work
-  but may be deprecated in future versions):
-
-  * The example code filter block delimiter is now the word `code`
-    followed by four or more tilde characters.
-  * The source highlight filter block delimiter is now the word
-    `source` followed by four or more tilde characters.
-
-- Conditionally redefined subscript and superscripting so they use the
-  old replacements mechanism when asciidoc7compatible is defined
-  rather than the asciidoc 8 default unconstrained quoting (patch for
-  affected files attached).
-- Moved the source highlight filter from `./examples/` to `./filter/`.
-- Added `{verbose}` intrinsic attribute (useful for passing verbose
-  flag to filters).
-- Added `{outdir}` intrinsic attribute.
-- Renamed `{docdir}` intrinsic attribute to unambiguous `{indir}`
-  (`{docdir}` still works but may be removed in future release).
-- If `asciidoc(1)` outputs to stdout then intrinsic attribute
-  `{docname}` is extracted from the input file name.
-
-
-Version 8.0.0 (2006-08-27)
---------------------------
-*********************************************************************
-This is a major release because changes to quoting and index entry
-handling may break existing documents (see 'Additions and changes'
-below and 'Appendix A: Migration Notes' in the AsciiDoc User Guide).
-
-Please report any problems you encounter.
-
-mailto:srackham@gmail.com'Stuart Rackham'
-*********************************************************************
-
-.Additions and changes
-- Quoting can can occur within words (based on patch submitted by
-  Benjamin Klum). See the 'Unconstrained Quotes' sub-section in the
-  User Guide.
-
-- The underline and plus characters can be used as alternatives to the
-  existing apostrophe and backtick quote characters. They are arguably
-  better choices than the apostrophe and backtick as they are not
-  confused with punctuation.
-
-- The syntax for index entry macros have have been deprecated from
-  `+...+` and `++...++` to `((...))` and `(((...)))` respectively.
-  Rationale:
-  * Bracketing is consistent other with `...` and `<<...>>`
-    reference macros.
-  * To easily confused with triple plus passthroughs.
-  * To make way for the new monospace quoting.
-
-- Superscripts and subscripts are implemented as constrained quotes so
-  they can now be escaped with a leading backslash and prefixed with
-  with an attribute list.
-
-- An experimental LaTeX backend has been written by Benjamin Klum (a
-  number additions in this release are to accommodate the LaTeX
-  backend).
-- `include` macro file names now expand environment variables and
-  tilde expansions.
-- A configuration file `quotes` entry can be undefined by setting to
-  a blank value.
-- Added `callto` inline macro for Skype 'callto' links.
-- Added `colnumber` attribute for table data markup.
-- A leading comment block or comment lines are now skipped (previously
-  a document had to start with either attribute entries or a document
-  Title).
-- Experimental `rows` attribute (number of source lines in table)
-  available in table markup templates (used by experimental LaTeX
-  backend).
-- Included install shell script written by mailto:jlm@ofb.netJacob
-  Mandelson for installing the tarball distribution.
-- Added INSTALL documentation file.
-- Added 'replacements2' substitution options -- a second replacements
-  section.
-- Added the ability to redefine 'normal' and 'verbatim' substitutions
-  with `subsnormal` and `subsverbatim` entries in configuration file
-  `miscellaneous` section.
-- By default `AttributeEntry` values are substituted for
-  `specialcharacters` and `attributes`, if you want a different
-  AttributeEntry substitution set the `attributeentry-subs` attribute.
-- The `name` in `name=value` configuration file entries can now end
-  with a backslash, just escape the trailing backslash with a
-  backslash. For example:
-
-  abc\\=xyz
-+
-Results in `name=abc\` and `value=xyz` --  previously this would have
-escaped the `=` character.
-
-- A blank configuration file section deletes any preceding section
-  with the same name (applies to non-markup template sections).
-- A command-line attribute value with a `@` suffix does not override
-  existing document and configuration file attributes (normally
-  command-line attributes have precedence over document and
-  configuration file attributes).
-- `localtime` attribute is now encoded from the native system encoding
-  to the output encoding. Patch submitted by
-  mailto:m_pupil@yahoo.com.cnFKtPp -- here's his description of the
-  problem:
-+
-``I am a Chinese user of AsciiDoc and I find that when I use UTF-8
-(the default encoding) to write asciidoc documents in Windows platform
-the resulting html footer line will get screwed. It was caused by a
-localized tzname that was always encoded in the windows native
-encoding, which in my case is 'cp936'.''
-
-- a2x(1) can generate Open Document Text files using
-  http://open.comsultia.com/docbook2odf/docbook2odf. Currently
-  `docbook2odf(1)` only processes a subset of DocBook, unimplemented
-  elements are skipped.
-- The a2x(1) format option defaults to `xhtml` (previously a format
-  had to be specified explicitly).
-- The `-d, \--doctype=DOCTYPE` option has been added to a2x(1) which
-  is a shortcut for `--asciidoc-options="--doctype=DOCTYPE"`.
-- Replaced a2x(1) `--no-icons` and `--no-copy` options with their
-  negated equivalents: `--icons` and `--copy` respectively. The
-  default behavior has also changed: copying and use of icons is
-  disabled by default. Rationale:
-  * To make the default behavior more consistent since use of icons
-    and CSS stylesheets does not apply to all formats.
-  * To make the default behavior less surprising (the creation of icon
-    and stylesheet output files must now be explicit).
-
-- a2x(1) has been bumped from version 0.1.1 to version 1.0.0.
-
-
-.Bug fixes
-- Removed duplicate `./doc/a2x.1.txt` from distribution tarball.
-- Documentation errata.
-- Attribute replacement is no longer performed twice in Titles and
-  AttributeEntrys.
-- a2x(1) skipped asciidoc(1) execution when rerun with different
-  `--asciidoc-options` options, it now always executes asciidoc(1).
-  The problem was that previously asciidoc(1) was executed only if the
-  output file was missing or older than the source file.
-
-
-Version 7.1.2 (2006-03-07)
---------------------------
-.Additions and changes
-- Support for
-  http://www1.chapman.edu/~jipsen/mathml/asciimath.htmlASCIIMathML
-  has been added. See 'Appendix I: ASCIIMathML Support' in the User
-  Guide and the examples at
-  http://asciidoc.org/asciimath.html.
-- You can now prefix quoted text with inline attributes lists.  You
-  can use this to set font size and color (XHTML and HTML outputs).
-- Added `##...##` quoting -- it does nothing -- it's purpose is to
-  allow inline attributes to be applied to normal text.
-- An 'inline passthrough' mechanism has been implemented.
-- Configuration file comment lines can be escaped with a backslash --
-  this is to allows the inclusion of configuration lines that start
-  with a hash character.
-- The `scriptsdir` attribute can be used to specify the name of the
-  directory containing linked JavaScripts (see the
-  link:userguide.html#X33User Guide for details.
-- The BackendBlock has been renamed PassthroughBlock for consistency
-  with the new inline passthrough naming.
-- `a2x(1)` now works with the older `bash(1)` version 2.05b. Patch
-  submitted by mailto:francis@daoine.orgFrancis Daly.
-- Content included by the `include1::` system macro is no longer
-  subject to attribute substitution so that ambiguities no longer
-  arise when used to include CSS or JavaScript files.
-
-
-Version 7.1.1 (2006-02-24)
---------------------------
-.Additions and changes
-- The `caption` attribute can be used to customize admonition captions
-  as well as image, table and example block element title prefixes
-  (`xhtml11` and `html4` backends).
-- You can now override the default icon image using the `icon`
-  attribute to specify the path of the linked image (xhtml11 and html4
-  backends only).
-- The deprecated `imagesdir` attribute is no longer recognized (use
-  `iconsdir` instead).
-- Added 'Appendix H: Using AsciiDoc with non-English Languages' to the
-  AsciiDoc User Guide.
-- Added 'Admonition Icons and Captions' subsection to the User Guide
-  explaining how to customize Admonition elements.
-
-.Bug fixes
-- `a2x(1)` failed when configuration files were installed in the
-  global `/etc/asciidoc/` directory -- it was only searching the
-  directory containing the asciidoc executable (thanks to Christian
-  Wiese for finding and submitting a patch this bug).
-- The html4 backend admonition caption now correctly displays the
-  admonition `caption` attribute (previously displayed the `style`
-  attribute).
-
-
-Version 7.1.0 (2006-01-13)
---------------------------
-.Additions and changes
-- `a2x(1)` toolchain wrapper utility.  This overcomes the biggest
-  hurdle for new users which seems to be assembling and using a
-  working DocBook XML toolchain. With `a2x(1)` you can generate XHTML
-  (chunked and unchunked), PDF, man page, HTML Help and text file
-  outputs from an AsciiDoc input file with a single command.  All you
-  need to install (in addition to AsciiDoc) is xsltproc(1), DocBook XSL
-  Stylesheets and optionally FOP (if you want PDF) or lynx(1) (if you
-  want text).
-- Block titles can now start with any non-space character (previously
-  where not allowed to start with `.~-_` characters).
-- `./stylesheets/docbook.css` renamed to
-  `./stylesheets/docbook-xsl.css` to clarify its function.
-- Renamed `./docbook-xsl/manpages.xsl` to `./docbook-xsl/manpage.xsl`
-  for consistency.
-- Admonition and navigation icons moved to `./images/icons/` to
-  clarify usage and conform with a2x(1) usage.
-- Renamed xhtml11 intrinsic attribute `imagesdir` to `iconsdir` to
-  keep vocab consistent and changed default value to `./images/icons`
-  (previously `./images`). `imagesdir` attribute still accepted but
-  deprecated.
-- Unused image files have been weeded out of the distribution.
-- Packager notes (appendix B) have been updated to reflect the needs
-  of `a2x(1)`.
-
-IMPORTANT: The renaming of the xhtml11 backend `imagesdir` intrinsic
-attribute and it's new default value introduces a backward
-compatibility issue: if you use the `icons` attribute you will need to
-either move your icons to the new default `./images/icons` location or
-include an `--attribute{nbsp}iconsdir="your_icons_path"` option in
-your asciidoc commands.
-
-.Bug fixes
-- Backslash line continuation is now observed in verbatim paragraphs.
-- Fixed errors generated by example
-  `./examples/website/build-website.sh` script.
-
-
-Version 7.0.4 (2005-12-08)
---------------------------
-.Additions and changes
-- Added ternary conditional attributes
-  `{<name>@<regexp>:<value1>:<value2>}` and
-  `{<name>$<regexp>:<value1>:<value2>}`.
-- Safety violations now generate errors (they previously generated
-  warnings).
-- asciidoc(1) now defaults to safe mode, consequently the
-  `miscellaneous` safe mode entry and `--safe` command-line option
-  are no longer necessary (though for backward compatibility
-  asciidoc(1) still accepts the `--safe` option).
-- Backend Blocks are now flagged unsafe (they could be used to include
-  arbitrary and hence potentially unsafe output content).
-- Filters are no longer considered unsafe. There's not much point in
-  insisting on filter safety since the installation of an unsafe
-  filter would require the introduction of new or modified
-  configuration files -- if your application configurations can be
-  compromised you're in all sorts of trouble (safe mode protects
-  against unsafe input files not unsafe configuration).  As with all
-  filters, before installing, you should verify that they can't be
-  coerced into generating malicious output or exposing sensitive
-  information.
-
-.Bug fixes
-- Fixed a lot of glaring grammatical and factual errors in the User
-  Guide.
-
-
-Version 7.0.3 (2005-12-01)
---------------------------
-.Additions and changes
-- Added `--safe` and `--unsafe` command-line options -- AsciiDoc can
-  now be executed in a 'safe mode' which disallows the execution of
-  arbitrary code or the inclusion of arbitrary files (see
-  link:userguide.html#X39Appendix C in the AsciiDoc User Guide).
-- Included link:source-highlight-filter.htmlsource-highlight filter
-  in the distribution `./examples/source-highlight-filter/` directory
-  (based on filter submitted by mailto:trolocsis@gmail.comRyan
-  Phillips).
-- Included the DocBook XSL Stylesheets 1.69.1 customizations used to
-  generate the distributed AsciiDoc documentation (read the
-  `asciidoc-docbook-xsl.txt` file in the distribution `./docbook-xsl/`
-  directory).
-- AsciiDoc DocBook XSL Stylesheet drivers moved from `./doc/` to
-  `./docbook-xsl/`.
-- Modified `./doc/manpages.xsl` so only URL content is displayed in
-  manpages.
-
-.Bug fixes
-- Explicitly set table CSS border style (`xhtml11` backend) to `solid`
-  because default border styles vary from browser to browser.
-
-
-Version 7.0.2 (2005-08-28)
---------------------------
-.Additions and changes
-- There are now long versions of all AsciiDoc options.
-- If the `--backend` is not specified it defaults to `xhtml11`.
-- Added CSS simulated frames layout to the examples website (see
-  `./examples/website/layout2/README-website.txt`). This layout does
-  not work with IE6 and the original tables based layout is still the
-  default.
-- Support page added to AsciiDoc website.
-
-.Bug fixes
-- Invalid options are now trapped gracefully.
-- Documentation errata.
-
-
-Version 7.0.1 (2005-06-24)
---------------------------
-.Additions and changes
-- Reverted to use of `strong`, `em`, `tt` XHTML tags -- they're more
-  obvious and no less correct than `span` tags, besides, the generated
-  file sizes are smaller (the 'User Guide' was 11% smaller).
-- Table title rendered with `caption` tag rather than a separate
-  `div`.
-- The AsciiDoc 'stylesdir' attribute (if specified) is now recognized
-  when searching for embedded stylesheets (previously only searched
-  default `./stylesheets` directory).
-- Default charset encoding changed from ISO-8859-1 to UTF-8 -- it's
-  less language specific and displays most common languages.
-- `template::` macros now expand in all configuration file sections
-  previously only in markup template sections.
-- Cleaned up example website layout CSS and configuration
-  (presentation has not been changed).
-- Refactored `xhtml11.conf` configuration file.
-- Set consistent and sensible permissions on distributed files.
-- White space is now stripped from DSV formatted table cell data.
-- `class="tableblock"` attribute added to tables generated by
-  `xhtml-deprecated-css.conf` to assist CSS.
-
-.Bug fixes
-- Illegal character set encoder (specified by the AsciiDoc `encoding`
-  attribute) and character data are trapped gracefully.
-- AsciiDoc table 'format' attribute in table attribute lists were not
-  recognized.
-- The nested horizontal labeled list example in the 'AsciiDoc User
-  Guide' has been dropped -- it generated invalid DocBook markup.
-
-
-Version 7.0.0 (2005-06-06)

-  and blocks to reproduce line breaks and white space from the source
-  document.
-- Replacements and Special Words can now be escaped with leading
-  backslashes.

-  ordering was indeterminate).
-- System macros can now be used in the base `asciidoc.conf`
-  configuration file.

-
-.Bug fixes
-- Included files are no longer read inside conditionally excluded
-  content.
-- Manpage command names containing dashes (in the manpage NAME
-  section) were misinterpreted as the spaced dash command name/purpose
-  separator.  Bug report and patch supplied by
-  mailto:david@dgreaves.comDavid Greaves.
-- Unexpected error following malformed author line error.
-
-
-Version 6.0.3 (2005-04-20)
---------------------------
-.Additions and changes
-- Special characters are now substituted in AttributeEntry element
-  values.
-- Spaced and unspaced em dashes are now recognized (previously only
-  spaced em dashes were recognized).
-- Replaced the table 'noborders' option with richer 'frame' and 'grid'
-  attributes.
-- The `duplicate macro` warning message now only occurs when the
-  verbose (`-v`) option is enabled.
-- Single lines starting with two forward slashes hard up against the
-  left margin are treated as comments and are not processed.
-- Renamed 'section' delimited block option to 'sectionbody' to more
-  accurately reflect it's role.
-- Added a List Continuation block -- a specialized delimited block
-  that is functionally equivalent to the List Item Continuation
-  feature except that the list contained within the block does not
-  require explicit '+' list item continuation lines.
-- Dropped deprecated `<u>` tags from generated HTML.
-- Literal Block delimiters must now consist of at least four points
-  (previously three) to avoid lone ellipsis ambiguity.
-
-.Bug fixes
-- Some system attribute evaluation failures caused unexpected
-  exceptions to occur.

-  `sys2` which are the block macro equivalents to the same named
-  system attributes.
-- 'Intrinsic' macros have been renamed 'system' macros along with
-  'action' attributes which have been renamed 'system' attributes:
-  * To reflect their common (though contextually different) behavior.
-  * To avoid confusion with 'intrinsic attributes'.
-
-.Bug fixes
-- Asciidoc now searches in `/etc/asciidoc/filters` for filters.
-
-
-Version 6.0.1 (2005-03-06)

-- A global configuration file location `/etc/asciidoc` has been added
-  and is now processed before all other locations (patch supplied by
-  mailto:stone@debian.orgFredrik Steen).

-
-
-Version 6.0.0 (2005-01-28)
---------------------------
-***************************************************
-This release has had some fairly major code and
-documentation changes. Please report any problems
-you encounter.
-
-mailto:srackham@gmail.com'Stuart Rackham'
-***************************************************
-
-A lot of new stuff. A new major version number -- some regression
-incompatibility (hopefully mitigated by 'deprecated' warnings).
-
-Went mad trying to rein in the current feature anarchy -- established
-a unified notion of document attributes. Attempted to introduce a
-consistent vocabulary -- renamed many poorly or inconsistently named
-entities.
-
-Actually, deprecated syntax is still processed correctly in almost all
-cases. One source of incompatibility that may arise if you have
-customized CSS stylesheets is the change of AsciiDoc CSS class names
-(see below). I guess the moral is if you've done a lot of
-configuration file customization and are happy with version 5 then you
-may want to stay put.
-
-NOTE: This version requires Python 2.3 or better to run.
-
-.Additions and changes
-- 'Glossary entries' have been renamed 'attributes'. This eliminates
-  confusion with the accepted meaning of glossary.
-- An `AttributeEntry` block element has been added so that document
-  attributes can be assigned from within an AsciiDoc document.
-- The `AttributeList` block element has been added which is a more
-  general solution than the (now deprecated) DelimitedBlock arguments.
-- An BlockId element has been added for setting block element anchor
-  (link target) IDs.
-- Quoted text can now span multiple lines (thanks to James Bowlin for
-  this patch).
-- Inline macros can now span multiple lines.
-- \``double backtick / apostrophe'' quotes generate ``curly quotes''.
-- A warning is now emitted for out of order list item (applies to
-  explicitly enumerated numbered list items).
-- Added `include` action attribute.
-- A line of three or more apostrophes generates an HTML horizontal
-  ruler (`<hr/>` tag). You will get a warning if processed with
-  non-HTML backend.
-- An `{imagesdir}` attribute specifies image file location for images
-  referenced in configuration files when generating HTML (the default
-  location is `images`).
-- An `{stylesdir}` attribute specifies the location of CSS
-  stylesheets when generating styled HTML (the default location for
-  configured markup is `.`).
-- The use of the (often inappropriately named) `{caption}` attribute
-  list entry has been deprecated, use `{0}` instead.
-- New 'ExampleBlock' delimited block along with associated variants
-  Note, Tip, Warning, Caution and Important.
-- The `docbook.conf` file now facilitates the optional inclusion of a
-  DocBook revision history file.
-- To better reflect their purpose the following block elements have
-  been renamed: `VerbatimBlock` to `ListingBlock`; `IndentedBlock` to
-  `LiteralBlock`; `IndentedParagraph` to `LiteralParagraph`;
-  `CustomBlock` to `BackendBlock`; `SimpleSection` to `SectionBody`.
-  Any corresponding CSS class names have also been changed which could
-  result in backward incompatibility in customized stylesheets.
-- Swapped plain DocBook admonition icons for Jimmac's DocBook icons
-  (http://jimmac.musichall.cz/ikony.php3). The original plain icons
-  have been moved to `./images/plain`.
-- Renamed `html` backend to `xhtml` to better reflect it's function
-  (former `html-4` backend renamed to `html`).
-- A new inline anchor macro syntax `<id>` is available, it
-  displays `<id>` at the anchor location and is for anchoring
-  bibliography list entries.
-- An optional 'single-line titles' syntax can be used.
-- Tweaks to distributed CSS stylesheets and FOP `fo.xsl` customization
-  file.
-- 'List Item Continuation' has been implemented which allows
-  additional block elements to be included in list items by separating
-  them from the preceding list item element with a line containing a
-  single plus character.
-- A new 'Horizontal Labeled List' list type has been added. Generates
-  two column list -- the first column contains the list element
-  labels, the second contains the element text. Same syntax as
-  `Vertical Labeled Lists` except the double colon label suffix is
-  followed by the start of the list item text.
-
-.Bug fixes
-- Fixed broken backslash line continuation.
-- Labeled list end tags were not undergoing attribute substitution.
-- Documents without any author information now generate legitimate
-  DocBook (previously if the author line was not included in the
-  document header then an empty (illegal) DocBook `author` element was
-  generated).
-- Multiple spaces in filter command arguments were replaced by a
-  single space. The `./examples/asciidoc2text/asciidoc2text.sh` script
-  now indents text correctly.
-
-
-Version 5.1.1 (2004-10-10)
---------------------------
-*15-December-2004: Interim update:* Updated `asciidoc.py` to fix
-broken `join_lines` function -- no other changes.
-
-- PDF documentation is now produced from DocBook XML using XSLTLib and
-  FOP. Previously we processed DocBook SGML with `jw(1)` (which used
-  Dvips to convert DVI files to PDF). FOP has come a long way in the
-  last 12 months and produces very acceptable PDF under both Linux and
-  Windows.
-- Sections detailing how to install and use the DocBook XSL
-  Stylesheets, xsltproc, FOP toolchain and the AsciiDoc XSLT drivers
-  have been added to the User Guide.
-- The PDF output from the he example article template has been
-  included in the distribution (`./doc/article.pdf`).
-- Special characters are emitted using decimal Unicode character codes
-  (previously used named character entities which cannot be assumed
-  included in non-HTML documents).
-- Added registered trademark (R) to `replacements`.
-- CSS stylesheet tweaks.
-- Admonitions (Note, Tip, Important, Warning, Caution) include icons
-  when generating css output.
-
-
-Version 5.1.0 (2004-09-18)
---------------------------
-- Callouts have been implemented (see the 'Callouts' section of the
-  AsciiDoc User Guide for details).
-- Added XSL drivers for generating XHTML, chunked XHTML and HTML Help
-  from DocBook XML using XSL stylesheets and xsltproc(1).
-- Added CSS stylesheet for HTML generated from DocBook XML using XSL
-  stylesheets.
-- Distribution contains HTML Help formatted User Guide
-  (`./doc/asciidoc.chm`), the User Guide tells you how it's generated.
-- Images referred to by distributed stylesheets are now located in the
-  `./images` subdirectory (previously located in `.`).
-- Filters path names are now handled properly under Cygwin.
-- The usual documentation and examples additions, updates and
-  polishing.
-
-
-Version 5.0.9 (2004-09-09)
---------------------------
-- The convention of using a `.asc` file extension for AsciiDoc files
-  has been dropped in favor of the familiar `.txt` extension. It makes
-  more sense in that AsciiDoc is a text presentation format and
-  because `.asc` clashed with the same extension used by other
-  applications.  It's only a naming convention -- you don't have to
-  switch if you don't want to.
-- Changed the subscript formatting character from underline to tilde
-  since underscores in file names are reasonably common (especially in
-  link and image macros).
-- An alternative syntax for the index term inline macro has been
-  added: `++<primary>,<secondary>,<tertiary>++`.
-- Index terms that have secondary and tertiary entries now
-  additionally generate separate index terms for the secondary and
-  tertiary entries.
-- A `+<primary>+` index term inline macro has been added which
-  displays the term in the primary text flow.
-- Added alternative variable list definition using double semi-colon
-  terminator as opposed to the standard double colon terminator so
-  variable lists can be nested to two levels.
-- Footnotes now appear on a separate line in HTML and Linuxdoc
-  outputs.
-- Python version compatibility is checked at startup.
-- Preface and appendix section titles in multi-part Book documents are
-  meant to be out of sequence -- warnings are no longer emitted when
-  outputting HTML.
-- Empty section warnings have been replaced by error messages and are
-  emitted only if invalid markup would result.
-- Missing macro sections or invalid macro name warnings are only
-  generated at startup if the `-v` (verbose) option is set. Otherwise
-  they are deferred until a matching macro is encountered in the input
-  file.
-- Missing or invalid table definition warnings are only generated at
-  startup if the `-v` (verbose) option is set. Otherwise they are
-  deferred until a matching table is encountered in the input file.
-- AsciiDoc now makes more of an effort to continue in the face of
-  errors.
-- Fixed broken `./examples/website/main.aap` script.
-- Converted distribution text files DOS text format as a sop to
-  Windows users with challenged text editors.
-- Documentation additions and corrections.
-
-
-Version 5.0.8 (2004-05-15)
---------------------------
-- Spurious 'out of sequence' level 2 warnings no longer appear when
-  processing 'book' document multi-part book top level Preface and
-  Appendix sub-sections since they are (correctly) out of sequence.
-- A warning is no longer emitted for empty Index sections since this
-  is normal when generating DocBook outputs.
-- Fixed: `quotes` configuration file entries where not being
-  overridden by downstream configuration file entries.
-- Footnote text is now output enclosed in square brackets in HTML
-  documents.
-- Added superscripts and subscripts to the standard PRS configuration
-  files.
-- Adjusted CSS stylesheets so list titles don't have so much space
-  between title and first list item (broken in IE6 due to poor CSS
-  compliance). Lessened sidebar title top margin.
-
-
-Version 5.0.7 (2004-04-22)
---------------------------
-- The version 5.0.6 README incorrectly stated that AsciiDoc would run
-  under Python 2.0, in fact it requires Python 2.1 or better. The
-  README has been corrected.
-- Documented techniques for combining and splitting AsciiDoc documents
-  and processing the combined and split parts (see the 'Tips and
-  Tricks' section of the User Guide).
-- An example of marking up superscripts and subscripts is documented
-  in the 'Tips and Tricks' section of the User Guide (the example
-  configuration file is in the AsciiDoc `examples` directory).
-- Added ellipsis to shipped `replacements`; three periods output an
-  ellipsis entity.
-- Removed unused 'SectionClose' class.
-- The AsciiDoc 'Preamble' element is output as a DocBook 'Preface'
-  when processed as a 'book' document type (in older AsciiDoc versions
-  a warning was issued and processing stopped).
-- Fixed a quoting anomaly: quoted text can no longer begin or end with
-  with white space.
-
-
-Version 5.0.6 (2004-03-07)
---------------------------
-- New 'image' macro implements optional image scaling and linking and
-  works in both inline and block contexts. The 'image' macro obsolesces
-  the existing 'graphic' block macro and 'icon' inline macro.
-- Macro substitution section names now have `-inlinemacro` and
-  `-blockmacro` suffixes to resolve context ambiguity, make their
-  purpose clearer and relieve section namespace congestion.
-- Header derived glossary entries can now be overridden from the
-  command-line.
-- Special character substitution is now performed on AuthorLine
-  derived author names.
-- A macro or block argument called 'options' can be used as a shortcut
-  for a list named arguments with zero length string values.
-- Tables can be output without borders using the `options="noborders"`
-  argument.
-- Table data lines that do not immediately follow a table section
-  underline can now be blank. This allows CSV data with embedded blank
-  lines to be processed correctly.
-- Blank DSV format table data lines are silently skipped.
-- Tightened up on enforcement of configuration file section names to
-  reduce the possibility of section content being seen as a section
-  header line.
-- Section titles can be optionally suffixed with title arguments
-  enclosed in double square brackets.
-- A replacement has been added to `asciidoc.conf` to replace inline
-  double dashes with the `&mdash;` entity.
-- Changed the `.UNDER-CONSTRUCTION.` macro syntax to
-  `#UNDER-CONSTRUCTION#` so it is not mistaken for a BlockTitle.
-  Similarly changed the `.NEW.` replacement with
-  `&#35;NEW&#35;`.
-- `&#35;NEW&#35;` and `#UNDER-CONSTRUCTION#` macros are now
-  included in the DocBook backend.
-- Replaced shipped `smallnew.gif` with `smallnew.png`.
-- Documentation tidy ups.
-
-
-Version 5.0.5 (2004-02-25)
---------------------------
-- Fixed the disappearing paragraph titles problem that was caused by
-  Inline macros (incorrectly) processing BlockTitles.
-- Tightened AuthorLine validation.  Previously invalid email addresses
-  and embedded special characters in the AuthorLine resulted in
-  invalid output markup.
-
-
-Version 5.0.4 (2004-02-09)
---------------------------
-- Reinstated missing `infile`, `outfile`, `filetype` and
-  `filetype-<filetype>` glossary entries.
-- As of version 5.0.3 asciidoc(1) now requires Python 2.0 or greater,
-  this has now been documented.
-
-
-Version 5.0.3 (2004-01-23)
---------------------------
-- Fixed problem that caused any filters directory file containing
-  `.conf` (not just those with the `.conf` extension) from being
-  loaded.
-- All `miscellaneous` configuration file entries can now be
-  referenced like glossary entries (they are now processed internally
-  as glossary entries).
-- The output file line terminator (previously hardwired to `\r\n` is
-  now set using the `newline` entry in the configuration file
-  `miscellaneous` section.
-- The misspelt `blocktitles` configuration file entry name has been
-  corrected (to `blocktitle`).
-- An `{empty}` glossary entry has been added to the default
-  configuration which is useful for outputting trailing blank lines
-  from configuration file substitution sections.
-
-
-Version 5.0.2 (2003-12-18)
---------------------------
-- New (alternative) 'anchor' and 'xref' macro syntax (old syntax still
-  valid).
-- DocBook `mediaobject` and `inlinemediaobject` tags are generated in
-  place of `graphic` and `inlinegraphic` tags by the AsciiDoc
-  `graphic` and `icon` macros. If a macro argument is specified it is
-  the alternative text output if the target document format does not
-  support the specified graphic file format.
-- Dropped the LinuxDoc left and right square bracket special character
-  substitutions as they interfered with macro substitution.
-- Documentation updates and corrections.
-
-
-Version 5.0.1 (2003-12-09)
---------------------------
-- Fixed problem with anchor tag when generating CSS styled HTML.
-
-
-Version 5.0 (2003-12-08)
-------------------------
-***************************************************
-This release has had some fairly major code and
-documentation changes. Please report any problems
-you encounter.
-
-mailto:srackham@gmail.com'Stuart Rackham'
-***************************************************
-
-- AsciiDoc can now produce a full-blown multi-part DocBook book
-  including dedication, abstract, preface, colophon, glossary,
-  appendix, bibliography and book part elements using the new
-  `specialsections` configuration file section.
-- All Section element children (Paragraph, DelimitedBlock, List,
-  Table, BlockMacro) can now be titled using the BlockTitle element.
-  A BlockTitle element is a single line containing a title and
-  beginning with a period.
-- The `index` and `backmatter` macros have been dropped, superseded by
-  `specialsections`.
-- The AsciiDoc 'Preface' element has been renamed 'Preamble' (to avoid
-  confusion with the DocBook book preface element).
-- Out of sequence titles are now tolerated with a warning. This allows
-  book document level 0 sections to be processed.
-- An 'anchor' inline macro has been added for document link target
-  creation.
-- 'Note', 'Tip', 'Important' and 'Warning' paragraph types have been
-  added to support the corresponding DocBook elements.
-- Title substitution is now performed in SidebarBlock titles.
-- DocBook graphics now output as `figure` and `informalfigure`
-  elements rather than `mediaobjects`. This ensures numbered figures
-  and a lists of figures are produced by the DocBook toolchain.
-- You can now escape block argument lines by appending a backslash.
-  Alternatively, if you embed arguments in the delimiter line AsciiDoc
-  does not check for an arguments line.
-- The default DocBook backend file extension has been changed from
-  `.docbook` to `.xml` (`.sgml` for the 'docbook-sgml' backend).
-- Warnings are output by default (previously they only printed when
-  verbose option enabled).
-- A Question and Answer variable list definition has been added to the
-  shipped configuration files, primarily to create DocBook `qanda`
-  DocBook elements.
-- Fixed broken code-filter `-b linuxdoc` option. The asciidoc.asc User
-  Guide can now be processed by linuxdoc(1) (although tables are
-  dropped because LinuxDoc does not implement tables).
-
-.Compatibility issues:
-1. Table titles are no longer in the arguments line, use the new
-   BlockTitles.
-2. Graphic titles are no longer in the 'graphic' block macro caption,
-   use the new BlockTitles.
-3. The code-filter title must be placed in a preceding BlockTitle.
-4. SidebarBlock titles must be placed in a preceding BlockTitle.
-5. The DelimitedBlock option 'sidebar' has been renamed to 'section'.
-6. The default DocBook backend file extension has been changed from
-`.docbook` to `.xml` (`.sgml` for the 'docbook-sgml' backend).
-
-
-Version 4.2 (2003-11-26)
-------------------------
-- The default HTML output is now XHTML 1.0 markup. To output the
-  former HTML 4 markup specify the `html-4` backend.
-- The default DocBook output is now DocBook XML. To output the former
-  DocBook SGML specify the `docbook-sgml` backend. The associated
-  `docbook-sgml.conf` file illustrates how to support minor DTD
-  variations. Examples of using the `xmlto(1)` command for DocBook
-  conversion have been added to the User Guide.
-- Glossary entries set using the command-line -g option can now be
-  referenced in configuration files.
-- Configuration dumps (`-c` command-line option) no longer output
-  redundant undefined glossary entries.
-- DelimitedBlock arguments can now be specified in a separate arguments
-  line immediately following the leading delimiter line, This is in
-  preference to the existing delimiter embedded arguments. Reasons:
-  * The syntax is in keeping with the Tables arguments syntax.
-  * It's easier to enter and implements line continuation.
-- A new QuoteBlock DelimitedBlock definition has been added to the
-  distribution configuration files.
-- The table arguments lines can be continued using the backslash line
-  continuation character.
-- Added new calculated glossary reference type `{<name>%<value>}`.
-- Double-quote characters can now appear in unquoted positional
-  arguments.
-
-
-Version 4.1 (2003-11-13)
-------------------------
-- Added DSV (Delimiter Separated Values) tables format.
-- `{eval:<expr>}` glossary references drop the containing line if
-  `<expr>` evaluates to `None`.
-- Block, Table and Macro arguments can now be positional (quoted or
-  unquoted).
-- Vocabulary change: DelimitedBlock, Table and Macro 'attributes' are
-  now referred to as 'arguments'. This makes more sense in light of the
-  extended syntax and avoids confusion with backend markup tag
-  attributes.
-- 'tablewidth' table ruler parameter can now be expressed in percent
-  units (0..100). If between 0 and 1 then the original fractional unit
-  measure is applied.
-- The use of quoting for generating footnotes and index entries has
-  been dropped in favor of 'footnote' and 'indexterm' inline macros.
-- 'backmatter' inline macro included in distribution.
-- Fixed: CSS styled HTML tables are now fully XHTML 1.0 conformant.
-- Fixed: 'tablewidth' was processed incorrectly when passed as table
-  argument.
-- Fixed: Glossary references like `{x=\{y}}` were one character off
-  if \{x was defined and `{y}` was not.
-

-Version 4.0 (2003-11-08)
-------------------------
-***************************************************
-This release has had some fairly major code and
-documentation changes. Please report any problems
-you encounter.
-
-'Stuart Rackham'
-***************************************************
-
-- Added tables to AsciiDoc.
-- Added two special 'subs' options: 'default' specifies the default
-  substitution options and 'none' specifies no substitution.  These
-  options can only appear singly.
-- Line continuation using a trailing backslash character is available
-  in Paragraphs, ListItems, Tables.
-- The left and right quotes for quoted text can now be specified
-  separately.
-- Shipped configuration files implement footnotes (only useful for
-  DocBook output) using \ quoting.
-- Shipped configuration files implement index terms (only useful for
-  DocBook and LinuxDoc output) using \(()) quoting.
-- The shipped 'html' backend configuration now emits valid 'HTML 4.01
-  Transitional'.
-- Added new calculated glossary reference types `{<name>!<value>}`
-  and `{<name>#<value>}`.
-- The DelimitedBlock 'params' option has been dropped in favor of the
-  new 'block attributes' mechanism. If you have customized block
-  params options you may need to adjust source files to use the
-  'block attributes' syntax. The example code filter has been updated
-  to reflect these changes.
-- The code filter now has a `-t tabsize` option.
-- Replaced `-w` option with `-v` (verbose) option. The warnings option
-  was just to confusing.
-- Named attributes can now be specified in macro calls.
-- The 'tabsize' attribute is recognized in the built-in `include`
-  macros. A tabsize of zero suppresses tab expansion.
-- The configuration file `options` section has been split into
-  `miscellaneous` and `titles`. If you have customized any of
-  these settings you will need to adjust the affected configuration
-  files.
-- Configuration file `miscellaneous` entries can now also be set
-  using the command-line `-g` option.
-- Fixed: error that occurred when attempting to use zero length
-  configuration and source files.
-- Fixed: blocking filter halt problem.
-- Fixed: inline macro escape prefix problem.
-- Fixed: missing macros from configuration dump problem.
-- Fixed: named macros were dumped incorrectly.
-- Many documentation changes/additions/corrections.
-
-
-Version 3.2.2 (2003-10-26)
---------------------------
-- Added `-n` option (synonym for `-g section-numbers`).
-- Dropped the processing commentary (hey, this is Unix).
-- Added new calculated glossary reference type `{<name>?<value>}`.
-  `<name>` is the glossary entry name and `<value>` is the text
-  substituted if the glossary entry is defined. `<value>` can only
-  contain literal text (no glossary references allowed).
-- Added `asciidoc2text` to distribution `examples/asciidoc2text`
-  directory (converts AsciiDoc source to text file with section
-  numbering).
-- Fixed incorrect nesting of Simple lists inside Variable lists.
-- List definitions have been modified so that list items can be
-  indented. This allows a more intuitive indentation of nested lists
-  in AsciiDoc source.
-- Lists must be separated from preceding paragraphs by a blank line.
-  This is to avoid paragraph lines being mistaken for list items.
-- Corrected asciidoc man page documentation error: the`-f` option does
-  *not* search relative to source document directory for the
-  configuration file.
-- Minor updates to various distribution `.conf` files.
-- Included `badges.conf` in `examples` directory.
-- `css-embedded-stylesheet.conf` now supports footer badges.
-- The default in-line element processing order has been changed:
-  Glossary References are now processed before Inline Macros. This
-  allows glossary expansions to occur inside macro references.
-- Glossary entries are now allowed in Author and Revision lines.
-- Default List `subs` options and Paragraph `presubs` options are
-  assigned the following default value if not specified:
-
-  specialcharacters,quotes,specialwords,replacements,glossary,macros
-
-- Documentation changes/additions/corrections.
-
-
-Version 3.2 (2003-05-26)
-------------------------
-- Added a `-s` command-line option to suppress the output of
-  `header` and `footer` sections.
-- Article document headers are no longer mandatory: this allows
-  AsciiDoc to process arbitrary chunks of text. When used in
-  conjunction with the new `-s` command-line option corresponding
-  chunks of backend markup can be generated.
-- AsciiDoc now emits a warning message and continues when an out of
-  sequence section title is detected (previously it failed and
-  halted). This allows document sections to be processed separately.
-- Optional 'presubs' and 'postsubs' entries have been added to
-  'DelimitedBlock' and 'Paragraph' definitions. As a consequence
-  substitution options are no longer legal in 'options' entries.
-- 'presubs' and 'postsubs' substitutions are processed in the order
-  the options are specified (rather than the fixed 'options' order of
-  previous versions).
-- ./filters subdirectories are automatically searched for filter
-  commands.
-- A 'title-subs' configuration option specifies the substitutions
-  performed on document Header and Section titles.
-- A 'subs' entry in now included in List configuration file
-  definitions that specified substitutions performed on list entry
-  text.
-- Configuration files are auto-loaded from ./filters subdirectories.
-- Added example code filter (see ./examples/filters).
-- Bug fix: if section was empty you may have got erroneous 'missing
-  tag "paragraph"' error.
-- Internal code tidy up.
-
-
-Version 3.1 (2003-05-18)
-------------------------
-- In version 3.0 a `macros` section entry of the form 'name' was
-  equivalent to 'name='. An entry of the form 'name' now undefines the
-  entry (to bring it in line with the behavior of other special
-  sections).
-- Paragraphs have now been generalized (in the same way as Lists and
-  DelimitedBlocks).
-- The 'indentsize' option has been dropped as as consequence of
-  paragraph generalization.
-- Pipe | characters can be included in substituted tag and
-  substitution section text using the \{brvbar} (broken vertical bar)
-  glossary reference.
-- Removed the restriction requiring substitution section text
-  placeholders | to be on a separate line.
-- Added an `-e` asciidoc(1) command option that excludes implicit
-  configuration files (used in conjunction with `-c` generated
-  configuration files).
-- Version 3.0 documentation has undergone a considerable cleanup.
-- The dumping of quoted section entries (see `-c` option) now works
-  correctly.
-- The format of special section entries has been made consistent:
-  `name` undefines the entry; `name=` sets the entry value to a blank
-  string; `name=value` sets the entry value to `value`.
-- As a consequence of the previous change the caret prefix is no
-  longer used in glossary configuration file entries (although it is
-  still used when undefining an entry using the `-g` command-line
-  option).
-
-
-Version 3.0 (2003-05-13)
-------------------------
-This version is the culmination of work begun in the 2.x releases
-whereby fixed policy has been replaced by extensible mechanisms.
-
-- Added `-c` command-line option to dump a composite asciidoc(1)
-  configuration file to stdout.
-- Lists and Delimited Blocks are now defined by a set of configuration
-  file parameter sections.  The user can modify the default
-  definitions or add new ones.
-- Block content can now be processed through external filters.
-- The default behavior for Custom Blocks is to perform glossary
-  substitution (previously there was no substitution inside Custom
-  Blocks).
-- The old 2.x style macros have been reimplemented; as with Lists and
-  Delimited Blocks there syntax and behavior can be configured by the
-  user. The default macro syntax remains the same but the semantics
-  are now (hopefully) a bit more intelligible.
-- Block and Builtin macros use :: delimiter instead of the 2.x single
-  colon delimit (to distinguish them from inline macros). The 2.x
-  syntax is still supported for backward compatibility.
-- Nested lists are now supported and IndentedParagraphs can be
-  included in list items.
-- Conditional source inclusion can be specified using built in `ifdef`,
-  `ifndef` and `endif` macros.
-- The new conditional source inclusion feature has been used to reduce
-  the number of default configuration files down to one per backend.
-- A change of name: 2.x 'Substitutions' are now called 'Replacements'
-  and the 2.x `substitutions` configuration file section is now
-  called `replacements` (the old name is still recognized for
-  backward compatibility).
-- The line break is now implemented as a 'Replacements' substitution.
-- Inline 'icon' macro for inline images has been added to default
-  configuration files.
-
-Version 2.2 (2003-04-07)
-------------------------
-- The `master.conf` configuration file name has been deprecated in
-  favor of `asciidoc.conf`.
-- The standard configuration files set is now loaded from the
-  `.asciidoc` folder in the users home directory (if it exists) and
-  then from the source document directory. Configuration files that
-  don't exist are silently skipped.
-- Configuration files named like the source file will be automatically
-  loaded if they are found in the source file directory. For example
-  if the source file is `mydoc.asc` and the `-b html` option is used
-  then asciidoc(1) will look for `mydoc.conf` and `mydoc-html.conf` in
-  that order.
-- The characters used to quote formatted text can be configured and
-  extended by the user (see the master.conf quotes section).
-- Quoted text can now be escaped by prefixing a backslash character to
-  the leading quote.
-- The double single-quote '' strong text quote has been deprecated in
-  favor of an asterisk * character.
-- Added \{eval:expression}, \{sys:command} and \{sys2:command}
-  glossary reference actions.
-- Trailing brace characters `}` are now allowed inside glossary
-  references provided they are escaped with a backslash character.
-- Glossary entries can now be escaped by prefixing a backslash
-  character to the leading brace character (use this in preference to
-  placing the backslash inside the brace).
-- The output macro has been deprecated (use the new include1 macro
-  inside a CustomBlock).
-- The default document type is `article` (asciidoc no longer attempts
-  to guess).
-- Files included within DelimitedBlocks are not searched for block
-  termination underlines. This ensures the entire file is part of the
-  DelimitedBlock.
-- `include` macros can now be used in configuration files.
-- Corrected \{infile} and \{outfile} glossary entry documentation.
-- File inclusion is now limited to a depth of 5 to catch recursion
-  loops.
-- Inline tags have been deprecated, they're not necessary and they
-  immediately make the source document backend specific. Use
-  CustomBlocks or Substitutions instead.
-
-Version 2.1 (2003-03-17)
-------------------------
-- Added section auto numbering `{sectnum}` glossary entry
-  (auto-numbering function contributed by Ludovico Magnocavallo).
-- asciidoc(1) now correctly returns non-zero exit status if an error
-  occurs.
-- An AsciiDoc example website has been included in the AsciiDoc
-  distribution `examples/website` directory.
-- NOTE: The `asciidoc` wrapper script included in the 2.0 distribution
-  has been dropped, if you've symlinked or aliased to `asciidoc` you'll
-  need to change them to point directly to `asciidoc.py` instead.
-- An RCS $Id$ marker can be used as the  document header revision line
-  (based on a patch submitted by Ludovico Magnocavallo).
-- In addition to the `name=value` glossary entry format two new ones
-  have been introduced: `name` (the default value is set to an empty
-  string) and `^name` (the glossary entry is undefined).
-- The `-q` command-line option has been deprecated and the `-w level`
-  command-line option added. +
-  NOTE: By default skipped substitution warnings are now suppressed.
-- If a configuration file specified with the `-f` command-line option
-  is not found relative to the current working directory then the
-  search is repeated relative to the asciidoc(1) directory. This
-  allows global configuration files to be used.
-- Added `{infile}`, `{outfile}` predefined glossary entries.
-- Added `under-construction` macro to HTML article configuration
-  files.
-- Deprecated `{asciidoc_version}` glossary entry in favor of
-  `{asciidoc-version}` (to it consistent with other entries).
-
-Version 2.0 (2003-02-24)
-------------------------
-- The emphasized, strong and monospaced words options have been
-  generalized with the introduction of macro based 'special words'
-  lists.
-- Glossary references can now appear in both the document and macro
-  bodies.
-- All output files use `crlf` line termination (previously used UNIX
-  `lf` (newline) termination).
-- Added substitutions section which implements arbitrary regular
-  expression based substitutions.
-- An optional `master.conf` configuration file can be used for entries
-  that are not backend or document type specific.
-- Special character definitions moved from the code to the new
-  special_characters configuration file section.
-- Configuration file glossary added.
-- Command-line -g glossary entry added.
-- A new 'book' document type has been implemented for the 'docbook'
-  backend. It outputs DocBook 'book' documents.
-- A major internal change has been the implementation of parametrized
-  user definable 'macros'. Internally most document elements are now
-  processed as macros.
-- Configuration file macro variables can be specified with default
-  values (literals or other macro variables).
-- An attempt has been made to tighten up the vocabulary used to
-  describe the AsciiDoc document syntax.
-- The term abstract has been replaced by the more general term
-  'preface' and a new preface section introduced into article
-  configuration files (replacing the synopsis sections).
-- Any section elements can now be put in the document preface
-  (previous versions only allowed paragraphs).
-- AsciiDoc Blocks have been unified and their behavior can be user
-  defined and parametrized.
-- An 'output' inclusion allows an external file to be written directly
-  to the backend output file.
-- A new CustomBlock has been added. Default behavior is to insert the
-  enveloped AsciiDoc source lines directly into the output file.
-- A 'line break' tag can be inserted by terminating a line with a '+'
-  character (only really useful for HTML backends).
-- An fourth section level has been introduced.
-- The SidebarBlock delimiter line characters have been changed. The
-  deprecated underline is still accepted.
-- Levels 2 and 3 title underline characters have been changed.  The
-  deprecated underlines are still accepted.
-- Lines with backend specific inline tags can be inserted into
-  AsciiDoc source files.
-- Single words enveloped by underscores are no longer emphasized. This
-  feature was deprecated as it is redundant (use single quotes
-  instead) and was being applied to file names with underscores.
-- A `-q` quiet option has been added to suppress warning messages.
-- Badge images sourced locally.
-- Added 'author' and 'author-mail' meta tags to HTML configuration
-  files.
-
-Version 1.5 (2003-01-08)
-------------------------
-- Implemented sidebar document elements.
-- Explicit checks for user specified configuration files and input
-  file (rather than throwing exception).
-
-Version 1.4 (2003-01-04)
-------------------------
-- New configuration file options 'emphasizedwords' and 'strongwords'.
-  These allow the definition of words that will always be emphasized
-  or rendered in a strong font without inline formatting.
-- Document and section titles are no long subject to inline
-  formatting.
-- Multiple configuration files can be overlaid in a single command.
-- Configuration file tags and options entries can now be overridden on
-  an entry by entry basis (previously the entire section was
-  overloaded).
-- Configuration file tags and options entries are now cached this has
-  resulted in around 37% performance improvement over version 1.3.
-- Variable lists can now contain multiple terms per list item.
-- Placeholder paragraph eliminated from empty sections that contain
-  subsections.
-- Added \{asciidoc_version} substitution variable.
-- More documentation additions and tidy ups.
-
-Version 1.3 (2003-01-01)
-------------------------
-- A new 'strong' text formatting convention has been implemented:
-  Word phrases enclosed in pairs of single quote characters (acute
-  accents) are rendered in a strong font (usually bold).
-- Paragraphs can now be followed immediately by Simple lists and
-  Ordered lists without an intervening blank line.
-- A user specified configuration file (`asciidoc(1)` -f option)
-  overlays the default configuration file rather than replacing it.
-  Custom configuration files need only contain those sections
-  that have been customized.
-- Comment Block delimiters have been relaxed slightly. They must start
-  with three forward slashes /// but the remainder can contain any
-  characters, this allows comments to be embedded in the delimiter line.
-- Leading non-digit characters preceding revision number are now
-  ignored.
-- Set default indentsize option from 2 to documented default value
-  of zero in HTML backend html-article.conf and html-manpage.conf
-  files.
-- Fixed error that occurred when taking input from stdin without
-  explicitly specifying a document type.
-- Restored file name and line number error message information.
-- Changed deprecated -t option to -d in asciidoc --help and usage
-  command output.
-- CSS styles tweaking.
-- Code, configuration file and documentation tidy ups.
-
-Version 1.2 (2002-12-28)
-------------------------
-- Implemented 'include' URL to allow file inclusion.
-- `fileextension` configuration file option renamed to more sensible
-  `outfilesuffix` (`fileextension` still accepted by this version but
-  will be dropped in future).
-- Improved error reporting.
-- CSS backends generate valid XHTML.
-- New `css-embedded` backend generates HTML with embedded stylesheets
-  (use the `css` backend for linked stylesheets). The css-embedded
-  backend output contains no linked images so the generated html files
-  are completely self contained.
-- Bug fixes.
-
-Version 1.1 (2002-12-03)
-------------------------
-- Added css (cascading style sheets) backend
-- Implemented IndentedBlock document element.
-- Tabsize command-line option has been deprecated in
-  favor of configuration file.
-- Default indent width changed to zero.
-- Added \{localdate} and \{localtime} substitution variables.
-- Added optional options configuration file section with
-  fileextension, tabsize and indentsize options.
-- Implemented \{authorinitials} substitution variable.
-- Added https link type.
-- Corrected graphic substitution from \{title} to \{caption}
-  in linuxdoc-article.conf configuration file.
-- Fixed error that occurred when '==' title underline was
-  used.
-
-Version 1.0 (2002-11-25)

-AsciiDoc Installation
-=====================
-
-NOTE: The current version of AsciiDoc requires *Python 3.5 or later*
-to run.  If you don't already have an up-to-date version of Python
-installed it can be downloaded from the official Python website
-http://www.python.org/.
-
-
-Prerequisites
--------------
-See the link:README.htmlREADME page.
-
-
-Installing from the GitHub repository
--------------------------------------
-The AsciiDoc repository is hosted by https://github.comGitHub.
-To browse the repository go to https://github.com/asciidoc/asciidoc-py3.
-You can install AsciiDoc from the repository if you don't have an up to
-date packaged version, or you want to get the latest version from the master
-branch:
-
-- Make sure you have https://git-scm.com/Git
-  installed; you can check with:
-
-  $ git --version
-
-- Go to the directory you want to install AsciiDoc into and download
-  the repository.  This example gets the {revnumber} tagged release:
-
-subs="attributes"
-  $ cd ~/bin
-  $ git clone https://github.com/asciidoc/asciidoc-py3 asciidoc-{revnumber}
-  $ git checkout {revnumber}
-
-You now have two choices: you can run asciidoc locally from your
-repository or you can use 'autoconf(1)' and 'make(1)' to perform a
-system-wide install.
-
-Running asciidoc from your local copy
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Create a symlink to the AsciiDoc script in a search `PATH` directory
-so it's easy to execute `asciidoc` from the command line, for example:
-
-subs="attributes"
-  $ ln -s ~/bin/asciidoc-{revnumber}/asciidoc.py ~/bin/asciidoc
-  $ ln -s ~/bin/asciidoc-{revnumber}/a2x.py ~/bin/a2x
-
-Use the git `pull` command to update your local AsciiDoc repository.
-
-Installing asciidoc for all users
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Create `configure` using 'autoconf(1)'; use `configure` to create the
-`Makefile`; run 'make(1)'; build the man pages; install:
-
----------------------------------------------
-$ autoconf
-$ ./configure
-$ make
-$ sudo make install
----------------------------------------------
-
-To uninstall:
-
----------------------------------------------
-$ sudo make uninstall
----------------------------------------------
-
-
-X1
-Distribution tarball installation
----------------------------------
-The distribution source tarballs can be downloaded from GitHub
-releases page https://github.com/asciidoc/asciidoc-py3/releases.
-
-If your flavor of UNIX or Linux does not have a packaged AsciiDoc
-distribution or if you prefer to install the latest AsciiDoc version
-from source, use the `configure` shell script in the tarball root
-directory.
-
-The `autoconf(1)`-generated `configure` script creates a `Makefile`
-that is tailored for your system. To install:
-
-subs="attributes"
-  $ tar -xzf asciidoc-{revnumber}.tar.gz
-  $ cd asciidoc-{revnumber}
-  $ ./configure
-  $ sudo make install
-
-To install the documentation:
-
-  $ sudo make docs
-
-To uninstall AsciiDoc:
-
-  $ sudo make uninstall
-
-If Vim is installed on your system the AsciiDoc Vim syntax highlighter
-and filetype detection are already installed as built into the vim runtime.
-
-
-X3
-Microsoft Windows installation
-------------------------------
-AsciiDoc is developed and tested on Linux but there seem to be quite a
-few people using it on Windows. To install AsciiDoc on Windows unzip
-the distribution zip file contents:
-
-subs="attributes"
-  $ unzip asciidoc-{revnumber}.zip
-
-This will create the folder +asciidoc-{revnumber}+ containing the
-`asciidoc.py` and `a2x.py` executables along with configuration files
-and documentation.
-
-To generate DocBook based outputs (e.g. PDFs) you will also need a
-working DocBook toolchain. Installing and configuring a DocBook
-toolchain on Windows can be a challenge -- this blog post explains
-http://blog.rainwebs.net/2010/02/25/how-to-create-handsome-pdf-documents-without-frustration/How
-to Create Handsome PDF Documents Without Frustration using
-http://www.cygwin.com/Cygwin,
-http://dblatex.sourceforge.net/dblatex and AsciiDoc.
-
-
-Testing your installation
--------------------------
-Test out asciidoc by changing to the AsciiDoc application directory
-and converting the User Guide document (`./doc/asciidoc.txt`) to XHTML
-(`./doc/asciidoc.html`):
-
-  $ python3 asciidoc.py doc/asciidoc.txt
-
-The link:testasciidoc.htmltestasciidoc tool offers a more extensive set of
-conformance tests. You can run the tests by executing this command:
-
-  $ python3 ./tests/testasciidoc.py run
-
-A full battery of tests can be run from the `Makefile` script in the
-distribution root directory:
-
-  $ make test
-
-
-X2
-Prepackaged AsciiDoc installation
----------------------------------
-The following platform-specific AsciiDoc packages are available:
-
-*Fedora Linux*::
-  AsciiDoc is included in Fedora Extras, which is available in
-  the default Fedora installation. To install asciidoc, execute the
-  following command:
-
-  $ yum install asciidoc
-
-*Ubuntu / Debian*::
-  AsciiDoc is included in Ubuntu / Debian package manager. To install,
-  execute the following command:
-
-  $ apt install asciidoc
-
-*macOS Homebrew*::
-  AsciiDoc has been packaged in homebrew and is installable using the
-  following command:
-
-  $ brew install asciidoc
-
-See also link:userguide.html#X38Packager Notes in the 'AsciiDoc User
-Guide'.

-
-AsciiDoc is a text document format for writing notes, documentation,
-articles, books, ebooks, slideshows, web pages, man pages and blogs.
-AsciiDoc files can be translated to many formats including HTML, PDF,
-EPUB, man page.
-
-AsciiDoc is highly configurable: both the AsciiDoc source file syntax
-and the backend output markups (which can be almost any type of
-SGML/XML markup) can be customized and extended by the user.
-
-Prerequisites
--------------
-AsciiDoc is written in Python so you need a Python interpreter
-(version 3.5 or later) to execute asciidoc(1). Python is installed by
-default in most Linux distributions.  You can download Python from the
-official Python website http://www.python.org.
-
-
-Obtaining AsciiDoc

-asciidocapi - AsciiDoc API wrapper class.
-
-The AsciiDocAPI class provides an API for executing asciidoc. Minimal example
-compiles `mydoc.txt` to `mydoc.html`:
-
-  import asciidocapi

-  asciidoc.execute('mydoc.txt')
-
-- Full documentation in asciidocapi.txt.
-- See the doctests below for more examples.
-
-Doctests:
-
-1. Check execution:
-
-   >>> import io
-   >>> infile = io.StringIO('Hello *{author}*')
-   >>> outfile = io.StringIO()
-   >>> asciidoc = AsciiDocAPI()
-   >>> asciidoc.options('--no-header-footer')

-   >>> asciidoc.execute(infile, outfile, backend='docbook')
-   >>> print(outfile.getvalue())

-
-2. Check error handling:

-ASCIIMathML Formulae
-====================
-
-http://www1.chapman.edu/~jipsen/mathml/asciimath.htmlASCIIMathML is
-a clever JavaScript written by Peter Jipsen that dynamically
-transforms mathematical formulae written in a wiki-like plain text
-markup to http://www.w3.org/Math/MathML markup which is displayed as
-standard mathematical notation by the Web Browser.  See 'Appendix E'
-in the AsciiDoc User Guide for more details.
-
-The AsciiDoc `xhtml11` backend supports ASCIIMathML -- it links the
-ASCIIMathML script and escapes ASCIIMathML delimiters and special
-characters to yield valid XHTML. To use ASCIIMathML:
-
-1. Include the `-a asciimath` command-line option when you run
-   `asciidoc(1)`.
-2. Enclose ASCIIMathML formulas inside math or double-dollar
-   passthroughs or in math passthrough blocks.
-
-Here's the link:asciimathml.txtAsciiDoc source that generated this
-page.
-
-.NOTE
-- When you use the `asciimath:` inline macro you need to escape ``
-  characters in the formulas with a backslash, escaping is unnecessary
-  if you use the double-dollar macro (for examples see the second
-  formula below).
-- See the
-  http://www1.chapman.edu/~jipsen/mathml/asciimath.htmlASCIIMathML
-  website for ASCIIMathML documentation and the latest version.
-- If the formulas don't appear to be correct you probably need to
-  install the correct math fonts (see the
-  http://www1.chapman.edu/~jipsen/mathml/asciimath.htmlASCIIMathML
-  website for details).
-- See the link:latexmathml.htmlLaTeXMathML page if you prefer to use
-  LaTeX math formulas.
-
-A list of example formulas:
-
-- $$`a,b,c,d((n),(k))`$$
-- asciimath:x/x={(1,if x!=0),(text{undefined},if x=0):}
-- asciimath:d/dxf(x)=lim_(h->0)(f(x+h)-f(x))/h
-- +++`sum_(i=1)\^n i=(n(n+1))/2`$+++ and *bold
-  asciimath:int_0\^(pi/2) sinx\ dx=1*
-- asciimath:(a,b\={x in RR : a < x <= b}
-- asciimath:x^2+y_1+z_12^34
-
-*********************************************************************
-The first three terms factor to give
-asciimath:(x+b/(2a))^2=(b^2)/(4a^2)-c/a.
-
-asciimath:x+b/(2a)=+-sqrt((b^2)/(4a^2)-c/a).
-
-Now we take square roots on both sides and get
-asciimath:x+b/(2a)=+-sqrt((b^2)/(4a^2)-c/a).
-Finally we move the asciimath:b/(2a) to the right and simplify to
-get the two solutions:
-*asciimath:x_(1,2)=(-b+-sqrt(b^2-4ac))/(2a)*.

-NAME
-    code-filter - AsciiDoc filter to highlight language keywords
-
-SYNOPSIS
-    code-filter -b backend -l language  -t tabsize 
-                 --help | -h   --version | -v 
-
-DESCRIPTION
-    This filter reads source code from the standard input, highlights language
-    keywords and comments and writes to the standard output.
-
-    The purpose of this program is to demonstrate how to write an AsciiDoc
-    filter -- it's much to simplistic to be passed off as a code syntax
-    highlighter. Use the 'source-highlight-filter' instead.
-
-
-OPTIONS
-    --help, -h
-        Print this documentation.
-
-    -b
-        Backend output file format: 'docbook', 'linuxdoc', 'html', 'css'.
-
-    -l
-        The name of the source code language: 'python', 'ruby', 'c++', 'c'.
-
-    -t tabsize
-        Expand source tabs to tabsize spaces.
-
-    --version, -v
-        Print program version number.
-
-BUGS
-    - Code on the same line as a block comment is treated as comment.
-      Keywords inside literal strings are highlighted.
-    - There doesn't appear to be an easy way to accommodate linuxdoc so
-      just pass it through without markup.

-NAME
-    latex2img - Converts LaTeX source to PNG or SVG file
-
-SYNOPSIS
-    latex2img options INFILE
-
-DESCRIPTION
-    This filter reads LaTeX source text from the input file
-    INFILE (or stdin if INFILE is -) and renders it to PNG image file.
-    Typically used to render math equations.
-
-    Requires latex(1), dvipng(1) and/or dvisvgm(1) commands and LaTeX math
-    packages.
-
-OPTIONS
-    -D DPI
-        Set the output resolution for PNG images to DPI dots per inch. Use
-        this option to scale the output PNG image size.
-
-    -o OUTFILE
-        The file name of the output file. If not specified the output file is
-        named like INFILE but with an extension matching the chosen output
-        image format, .png for PNG images and .svg for SVG images.
-
-    -m
-        Skip if the output image file is newer than the INFILE.
-        Compares timestamps on INFILE and OUTFILE. If
-        INFILE is - (stdin) then compares MD5 checksum stored in file
-        named like OUTFILE but with a .md5 file name extension.
-        The .md5 file is created if the -m option is used and the
-        INFILE is - (stdin).
-
-    -v
-        Verbosely print processing information to stderr.
-
-    --help, -h
-        Print this documentation.
-
-    --version
-        Print program version number.

-DESCRIPTION
-    This filter reads LilyPond or ABC music notation text from the input file
-    INFILE (or stdin if INFILE is -), converts it to classical music notation
-    and writes it to a trimmed PNG image file.
-
-    This script is a wrapper for LilyPond and ImageMagick commands.
-
-OPTIONS
-    -f FORMAT
-        The INFILE music format. 'abc' for ABC notation, 'ly' for LilyPond
-        notation. Defaults to 'abc' unless source starts with backslash.
-
-    -o OUTFILE
-        The file name of the output file. If not specified the output file is
-        named like INFILE but with a .png file name extension.
-
-    -m
-        Skip if the PNG output file is newer that than the INFILE.
-        Compares timestamps on INFILE and OUTFILE. If
-        INFILE is - (stdin) then compares MD5 checksum stored in file

-NAME
-
-   asciidoc - converts an AsciiDoc text file to HTML or DocBook
-
-SYNOPSIS
-
-   asciidoc OPTIONS FILE
-
-DESCRIPTION
-
-   The asciidoc(1) command translates the AsciiDoc text file FILE to
-   DocBook or HTML. If FILE is - then the standard input is used.
-
-OPTIONS
-
-   -a, --attribute=ATTRIBUTE
-          Define or delete document attribute. ATTRIBUTE is formatted like
-          NAME=VALUE. Command-line attributes take precedence over
-          document and configuration file attributes. Alternate acceptable
-          forms are NAME (the VALUE defaults to an empty string); NAME!
-          (delete the NAME attribute); NAME=VALUE@ (do not override
-          document or configuration file attributes). Values containing
-          spaces should be enclosed in double-quote characters. This
-          option may be specified more than once. A special attribute
-          named trace controls the output of diagnostic information.
-
-   -b, --backend=BACKEND
-          Backend output file format: docbook45, xhtml11, html4, html5,
-          slidy, wordpress or latex (the latex backend is experimental).
-          You can also use the backend alias names html (aliased to
-          xhtml11) or docbook (aliased to docbook45). Defaults to
-          html. The --backend option is also used to manage backend
-          plugins (see 1PLUGIN COMMANDS).
-
-   -f, --conf-file=CONF_FILE
-          Use configuration file CONF_FILE.Configuration files processed
-          in command-line order (after implicit configuration files). This
-          option may be specified more than once.
-
-   --doctest
-          Run Python doctests in asciidoc module.
-
-   -d, --doctype=DOCTYPE
-          Document type: article, manpage or book. The book document type
-          is only supported by the docbook backend. Default document type
-          is article.
-
-   -c, --dump-conf
-          Dump configuration to stdout.
-
-   --filter=FILTER
-          Specify the name of a filter to be loaded (used to load filters
-          that are not auto-loaded). This option may be specified more
-          than once. The --filter option is also used to manage filter
-          plugins (see 2PLUGIN COMMANDS).
-
-   -h, --help TOPIC
-          Print help TOPIC. --help topics will print a list of help
-          topics, --help syntax summarizes AsciiDoc syntax, --help manpage
-          prints the AsciiDoc manpage.
-
-   -e, --no-conf
-          Exclude implicitly loaded configuration files except for those
-          named like the input file (infile.conf and infile-backend.conf).
-
-   -s, --no-header-footer
-          Suppress document header and footer output.
-
-   -o, --out-file=OUT_FILE
-          Write output to file OUT_FILE. Defaults to the base name of
-          input file with backend extension. If the input is stdin then
-          the outfile defaults to stdout. If OUT_FILE is - then the
-          standard output is used.
-
-   -n, --section-numbers
-          Auto-number HTML article section titles. Synonym for --attribute
-          numbered.
-
-   --safe
-          Enable safe mode. Safe mode is disabled by default. AsciiDoc
-          safe mode skips potentially dangerous scripted sections in
-          AsciiDoc source files.
-
-   --theme=THEME
-          Specify a theme name. Synonym for --attribute theme=THEME. The
-          --theme option is also used to manage theme plugins (see
-          3PLUGIN COMMANDS).
-
-   -v, --verbose
-          Verbosely print processing information and configuration file
-          checks to stderr.
-
-   --version
-          Print program version number.
-
-PLUGIN COMMANDS
-
-   The asciidoc(1) --filter, --backend and --theme options are used to
-   install, remove and list AsciiDoc filter, backend and theme plugins.
-   Syntax:
-
-          asciidoc OPTION install ZIP_FILE PLUGINS_DIR
-          asciidoc OPTION remove PLUGIN_NAME PLUGINS_DIR
-          asciidoc OPTION list
-          asciidoc OPTION build ZIP_FILE PLUGIN_SOURCE
-
-   Where:
-
-   OPTION
-          asciidoc(1) --filter, --backend or --theme option specifying the
-          type of plugin.
-
-   PLUGIN_NAME
-          A unique plugin name containing only alphanumeric or underscore
-          characters.
-
-   ZIP_FILE
-          A Zip file containing plugin resources, the name must start with
-          the plugin name e.g. my_filter-1.0.zip packages filter
-          my_filter.
-
-   PLUGINS_DIR
-          The directory containing installed plugins. Each plugin is
-          contained in its own separate subdirectory which has the same
-          name as the plugin. PLUGINS_DIR defaults to the
-          $HOME/.asciidoc/filters (for filter plugins) or
-          $HOME/.asciidoc/backends (for backend plugins) or
-          $HOME/.asciidoc/themes (for theme plugins).
-
-   PLUGIN_SOURCE
-          The name of a directory containing the plugin source files or
-          the name of a single source file.
-
-   The plugin commands perform as follows:
-
-   install
-          Create a subdirectory in PLUGINS_DIR with the same name as the
-          plugin then extract the ZIP_FILE into it.
-
-   remove
-          Delete the PLUGIN_NAME plugin subdirectory and all its contents
-          from the PLUGINS_DIR.
-
-   list
-          List the names and locations of all installed filter or theme
-          plugins (including standard plugins installed in the global
-          configuration directory).
-
-   build
-          Create a plugin file named ZIP_FILE containing the files and
-          subdirectories specified by PLUGIN_SOURCE. File and directory
-          names starting with a period are skipped.
-
-EXIT STATUS

-==============
-This file contains JavaScript functions to convert ASCII math notation
-to Presentation MathML. The conversion is done while the (X)HTML page
-loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet
-Explorer 6+MathPlayer (http://www.dessci.com/en/products/mathplayer/).
-Just add the next line to your (X)HTML page with this file in the same folder:
-This is a convenient and inexpensive solution for authoring MathML.

-<div class="paragraph"><p><a href="http://www1.chapman.edu/~jipsen/mathml/asciimath.html">ASCIIMathML</a> is
-a clever JavaScript written by Peter Jipsen that dynamically
-transforms mathematical formulae written in a wiki-like plain text
-markup to <a href="http://www.w3.org/Math/">MathML</a> markup which is displayed as
-standard mathematical notation by the Web Browser.  See <em>Appendix E</em>
-in the AsciiDoc User Guide for more details.</p></div>

-<li>

-<p>
-When you use the <span class="monospaced">asciimath:</span> inline macro you need to escape <span class="monospaced"></span>

-  if you use the double-dollar macro (for examples see the second

-If the formulas don&#8217;t appear to be correct you probably need to

-This file contains JavaScript functions to convert ASCII math notation
-to Presentation MathML. The conversion is done while the (X)HTML page
-loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet
-Explorer 6+MathPlayer (http://www.dessci.com/en/products/mathplayer/).
-Just add the next line to your (X)HTML page with this file in the same folder:
-This is a convenient and inexpensive solution for authoring MathML.

-AsciiDoc Website
-================
-
-The AsciiDoc website source is included in the AsciiDoc distribution
-as an example of using AsciiDoc to build a website. The files are
-principally located under `/doc` and `/website`, with a handful of
-files pulled in from the root directory.
-
-A simple shell script (`./build_website.sh`) will
-build the site's web pages -- just set the `LAYOUT` variable to the
-desired layout.
-
-Website Layouts
----------------
-The website layout is determined by the layout configuration file
-(`layout1.conf` or `layout2.conf`) and corresponding layout CSS file
-(`layout1.css` or `layout2.css`). The example website comes with the
-following layouts:
-
-width="80%",cols="1,4",options="header"
-|====================================================================
-|Layout   |  Description
-|layout1  |  Table based layout
-|layout2  |  CSS based layout (this is the default layout)
-|====================================================================
-
-The default tables based layout (layout1) works with most modern
-browsers.
-
-NOTE: The simulated frames layout (layout2) does not work with IE6.

-************************************************************************
-Read the link:CHANGELOG.htmlCHANGELOG for release highlights and a

-documented in the updated link:userguide.htmlUser Guide. See the
-link:INSTALL.htmlInstallation page for downloads and and

-************************************************************************
-
-Introduction
-------------
-{description}
-
-AsciiDoc is highly configurable: both the AsciiDoc source file syntax
-and the backend output markups (which can be almost any type of
-SGML/XML markup) can be customized and extended by the user.
-
-AsciiDoc is free software and is licensed under the terms of the 'GNU
-General Public License version 2' (GPLv2).
-
-TIP: The pages you are reading were written using AsciiDoc, to view
-the corresponding AsciiDoc source click on the *Page Source* menu item
-in the left hand margin.
-
-
-Overview and Examples
----------------------
-You write an AsciiDoc document the same way you would write a
-normal text document, there are no markup tags or weird format
-notations. AsciiDoc files are designed to be viewed, edited and
-printed directly or translated to other presentation formats using
-the asciidoc(1) command.
-
-The asciidoc(1) command translates AsciiDoc files to HTML, XHTML and
-DocBook markups.  DocBook can be post-processed to presentation
-formats such as HTML, PDF, EPUB, DVI, LaTeX, roff, and Postscript
-using readily available Open Source tools.
-
-Example Articles
-~~~~~~~~~~~~~~~~
-- This XHTML version of the
-  link:asciidoc.css-embedded.htmlAsciiDoc User Guide
-  was generated by AsciiDoc from
-  link:asciidoc.txtthis AsciiDoc file.
-
-- Here's the link:asciidoc.htmlsame document created by first
-  generating DocBook markup using AsciiDoc and then converting the
-  DocBook markup to HTML using 'DocBook XSL Stylesheets'.
-
-- The User Guide again, this time a
-  link:chunked/index.htmlchunked version.
-
-- AsciiDoc generated this link:article-standalone.htmlstand-alone
-  HTML file containing embedded CSS, JavaScript and images from this
-  link:article.txtAsciiDoc article template with this command:
-
-  asciidoc -a data-uri -a icons -a toc -a max-width=55em article.txt
-
-- The same link:article.txtAsciiDoc article template generated
-  link:article-html5-toc2.htmlthis HTML 5 (the 'toc2' attribute puts
-  a table of contents in the left margin) from this command:
-
-  asciidoc -b html5 -a icons -a toc2 -a theme=flask article.txt
-
-- The same link:article.txtAsciiDoc article template produced
-  this link:article.htmlHTML file and this
-  link:article.pdfPDF file via DocBook markup generated by AsciiDoc.
-
-X7
-Example Books
-~~~~~~~~~~~~~
-AsciiDoc markup supports all the standard DocBook frontmatter and
-backmatter sections (dedication, preface, bibliography, glossary,
-index, colophon) plus footnotes and index entries.
-
-- This link:book.txtAsciiDoc book produced link:book.htmlthis HTML
-  file using the 'DocBook XSL Stylesheets'.
-- The link:asciidoc.pdfPDF formatted AsciiDoc User Guide was
-  generated from asciidoc(1) DocBook output.
-- The link:asciidoc.epubEPUB formatted AsciiDoc User Guide was
-  generated using link:a2x.1.htmla2x.
-- This link:book.epubEPUB formatted book skeleton was generated
-  using link:a2x.1.htmla2x.
-- This link:book-multi.txtmulti-part AsciiDoc book produced
-  link:book-multi.htmlthis HTML file using the 'DocBook XSL
-  Stylesheets'.
-
-Example UNIX Man Pages
-~~~~~~~~~~~~~~~~~~~~~~
-HTML formatted AsciiDoc man pages
-link:asciidoc.1.css-embedded.htmlwith stylesheets and
-link:asciidoc.1.htmlwithout stylesheets were generated by AsciiDoc
-from link:asciidoc.1.txtthis file.
-
-This link:asciidoc.1roff formatted  man page was generated from
-asciidoc(1) DocBook output using `xsltproc(1)` and DocBook XSL
-Stylesheets.
-
-X8
-Example Slideshows
-~~~~~~~~~~~~~~~~~~
-The http://www.w3.org/Talks/Tools/Slidy2/Slidy backend generates
-HTML slideshows that can be viewed in any web browser.  What's nice is
-that you can create completely self contained slideshows including
-embedded images.
-
-- Here is the link:slidy.htmlslidy backend documentation slideshow
-  and here is it's link:slidy.txtAsciiDoc source.
-- An link:slidy-example.htmlexample slidy slideshow and the
-  link:slidy-example.txtAsciiDoc source.
-
-Example Web Site
-~~~~~~~~~~~~~~~~
-The link:README-website.htmlAsciiDoc website is included in the
-AsciiDoc distribution (in `./website/` and `./docs/`) as an example website
-built using AsciiDoc.  See `./website/README-website.txt`.
-
-More examples
-~~~~~~~~~~~~~
-- See below: <<X6,'Documents written using AsciiDoc'>>.
-- Example link:newtables.htmlTables.

-weblog posts and pages directly from AsciiDoc source documents.
-
-
-Source code highlighter
------------------------
-AsciiDoc includes a link:source-highlight-filter.htmlsource code
-highlighter filter that uses
-http://www.gnu.org/software/src-highlite/GNU source-highlight to
-highlight HTML outputs. You also have the option of using the
-http://pygments.org/Pygments highlighter.
-
-
-X3
-Mathematical Formulae
----------------------
-You can include mathematical formulae in AsciiDoc XHTML documents using
-link:asciimathml.htmlASCIIMathML or link:latexmathml.htmlLaTeXMathML
-notation.
-
-The link:latex-filter.htmlAsciiDoc LaTeX filter translates LaTeX
-source to an image that is automatically inserted into the AsciiDoc
-output documents.

-LaTeX Backend
--------------
-An experimental LaTeX backend was written for AsciiDoc in 2006 by
-Benjamin Klum.  Benjamin did a superhuman job (I admit it, I didn't
-think this was doable due to AsciiDoc's SGML/XML bias).  Due to
-other commitments, Benjamin was unable to maintain this backend.
-Here's link:latex-backend.htmlBenjamin's original documentation.
-Incompatibilities introduced after AsciiDoc 8.2.7 broke the LaTeX
-backend.
-
-In 2009 Geoff Eddy stepped up and updated the LaTeX backend, thanks to
-Geoff's efforts it now works with AsciiDoc 8.4.3. Geoff's updated
-`latex.conf` file shipped with AsciiDoc version 8.4.4. The backend
-still has limitations and remains experimental (see
-link:latex-bugs.htmlGeoff's notes).
-
-It's probably also worth pointing out that LaTeX output can be
-generated by passing AsciiDoc generated DocBook through `dblatex(1)`.
-
-
-Patches and bug reports
------------------------
-Patches and bug reports are are encouraged, but please try to follow
-these guidelines:
-
-- Post bug reports and PRs to the
-  https://github.com/asciidoc/asciidoc-py3asciidoc-py3 repository.
-- Post questions about using AsciiDoc or AsciiDoc  syntax to the
-  http://groups.google.com/group/asciidocasciidoc discussion list,
-  this keeps things transparent and gives everyone a chance to
-  comment.
-
-=== Bug reports
-- When reporting problems please illustrate the problem with the
-  smallest possible example that replicates the issue (and please test
-  your example before posting). This technique will also help to
-  eliminate red herrings prior to posting.
-- Paste the commands that you executed along with any relevant
-  outputs.
-- Include the version of AsciiDoc and the platform you're running it
-  on.
-- If you can program please consider writing a patch to fix the
-  problem.
-
-=== Pull Requests
-- Keep pull requests small and atomic (one issue per PR) -- no patch
-  bombs.
-- If possible test your PR against the current master.
-- If your PR adds or modifies functionality include a short example
-  that illustrates the changes.
-- Include documentation updates if you're up to it; otherwise insert
-  'TODO' comments at relevant places in the documentation.

-AsciiDoc New Lists
-==================
-
-*New in version 8.3.0*
-
-Lists can now be styled like other block elements, this allows the
-normal bulleted and labeled list syntax to be used for 'glossary',
-'qanda' (Question and Answer) and 'bibliography' lists instead of
-having to remember a different syntax for each one. In the same vein
-there is only one labeled list syntax, horizontal labeled lists are
-rendered by applying the 'horizontal' style. Examples:
-
----------------------------------------------------------------------
-glossary
-A glossary term::
-    The corresponding definition.
-A second glossary term::
-    The corresponding definition.
-
-horizontal
-Lorem:: Fusce euismod commodo velit.
-Ipsum:: Vivamus fringilla mi eu lacus.
----------------------------------------------------------------------
-
-The list related stuff in the configuration files has been
-rationalized with separate 'listtags-\*' sections (c.f. table
-'tabletags-*' sections). The old list tags are no longer supported so
-you'll need to update your custom configuration file list definitions.
-
-These changes necessitated the following backward incompatibilities:
-
-. You have to explicitly precede horizontal labeled lists with the
-  `horizontal` style attribute -- if you do nothing the existing
-  horizontal labeled lists will be rendered vertically.
-. The old 'compact' list style is now implemented as a list option, to
-  update replace `compact` with `options="compact"`. You can now
-  apply the 'compact' option globally by setting the `compact-option`
-  document attribute.
-. You'll need to update any customized configuration file list
-  definitions that have been made.

-AsciiDoc Version 8.3
-====================
-
-This is significant release, it gets rid of unused cruft, simplifies
-the https://asciidoc.org/newlists.htmllists syntax and
-introduces a decent
-https://asciidoc.org/newtables.htmltables syntax.
-There are a few fairly minor backward compatibility issues, please
-read the link:CHANGELOG.html#X1compatibility issues section in the
-CHANGLOG before upgrading.
-
-New Features
-------------
-- AsciiDoc tables have been redesigned.  The link:newtables.htmlnew
-  syntax and features are a huge improvement over the old tables. The
-  old tables syntax has been deprecated but is currently still
-  processed.
-- Lists can now be styled like other block elements. This allows a
-  single list syntax for 'glossary', 'qanda' (Question and Answer) and
-  'bibliography' lists instead of having to remember a different
-  syntax for each type.  link:newlists.htmlHere is some more
-  information.
-- Inline passthroughs macros have been improved and block passthrough
-  macros added. Attribute substitution can be optionally specified
-  when the macro is called.
-- The passthrough block has a fully transparent passthrough delimited
-  block block style called 'pass'.
-- The 'asciimath' and 'latexmath' link:userguide.html#X77passthrough
-  macros along with 'asciimath' and 'latexmath'
-  link:userguide.html#X76passthrough blocks provide a (backend
-  dependent) mechanism for rendering mathematical formulas. There are
-  link:latexmath.pdfLaTeX Math, link:asciimathml.htmlAsciiMathML
-  and link:latexmathml.htmlLaTeXMathML examples on the AsciiDoc
-  website.
-
-Read the link:CHANGELOG.htmlCHANGELOG for a full list of all
-additions and changes.
