 """simplified reStructuredText parser.
 
 This parser knows just enough about reStructuredText to parse the
 Mercurial docstrings.
 
 It cheats in a major way: nested blocks are not really nested. They
 are just indented blocks that look like they are nested. This relies
 on the user to keep the right indentation for the blocks.
 
 Remember to update http://mercurial.selenic.com/wiki/HelpStyleGuide
 when adding support for new constructs.

   Using Additional Features
   """""""""""""""""""""""""
   
       Mercurial has the ability to add new features through the use of
       extensions. Extensions may add new commands, add options to existing
       commands, change the default behavior of commands, or implement hooks.
   
       To enable the "foo" extension, either shipped with Mercurial or in the
       Python search path, create an entry for it in your configuration file,
       like this:
   
         [extensions]
         foo =
   
       You may also specify the full path to an extension:
   
         [extensions]
         myfeature = ~/.hgext/myfeature.py
   
       See "hg help config" for more information on configuration files.
   
       Extensions are not loaded by default for a variety of reasons: they can
       increase startup overhead; they may be meant for advanced usage only; they
       may provide potentially dangerous abilities (such as letting you destroy
       or modify history); they might not be ready for prime time; or they may
       alter some usual behaviors of stock Mercurial. It is thus up to the user
       to activate extensions as needed.
   
       To explicitly disable an extension enabled in a configuration file of
       broader scope, prepend its path with !:
   
         [extensions]
         # disabling extension bar residing in /path/to/extension/bar.py
         bar = !/path/to/extension/bar.py
         # ditto, but no path was supplied for extension baz
         baz = !
   
       enabled extensions:
   
        children      command to display child changesets (DEPRECATED)
        rebase        command to move sets of revisions to a different ancestor

   hg verify
   
   verify the integrity of the repository
   
       Verify the integrity of the current repository.
   
       This will perform an extensive check of the repository's integrity,
       validating the hashes and checksums of each entry in the changelog,
       manifest, and tracked files, as well as the integrity of their crosslinks
       and indices.
   
       Please see http://mercurial.selenic.com/wiki/RepositoryCorruption for more
       information about recovery from corruption of the repository.
   
       Returns 0 on success, 1 if errors are encountered.
   
   (some details hidden, use --verbose to show complete help)
 
   $ hg help diff
   hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...
   
   diff repository (or selected files)
   
       Show differences between revisions for the specified files.
   
       Differences between files are shown using the unified diff format.
   
       Note:
          diff may generate unexpected results for merges, as it will default to
          comparing against the working directory's first parent changeset if no
          revisions are specified.
   
       When two revision arguments are given, then changes are shown between
       those revisions. If only one revision is specified then that revision is
       compared to the working directory, and, when no revisions are specified,
       the working directory files are compared to its parent.
   
       Alternatively you can specify -c/--change with a revision to see the
       changes in that changeset relative to its first parent.
   
       Without the -a/--text option, diff will avoid generating diffs of files it
       detects as binary. With -a, diff will generate a diff anyway, probably
       with undesirable results.
   
       Use the -g/--git option to generate diffs in the git extended diff format.
       For more information, read "hg help diffs".
   
       Returns 0 on success.
   
   options ([+] can be repeated):
   
    -r --rev REV [+]         revision
    -c --change REV          change made by revision
    -a --text                treat all files as text
    -g --git                 use git extended diff format
       --nodates             omit dates from diff headers
       --noprefix            omit a/ and b/ prefixes from filenames
    -p --show-function       show which function each change is in
       --reverse             produce a diff that undoes the changes
    -w --ignore-all-space    ignore white space when comparing lines
    -b --ignore-space-change ignore changes in the amount of white space
    -B --ignore-blank-lines  ignore changes whose lines are all blank
    -U --unified NUM         number of lines of context to show
       --stat                output diffstat-style summary of changes
       --root DIR            produce diffs relative to subdirectory
    -I --include PATTERN [+] include names matching the given patterns
    -X --exclude PATTERN [+] exclude names matching the given patterns
    -S --subrepos            recurse into subrepositories
   
   (some details hidden, use --verbose to show complete help)
 
   $ hg help status
   hg status [OPTION]... [FILE]...
   
   aliases: st
   
   show changed files in the working directory
   
       Show status of files in the repository. If names are given, only files
       that match are shown. Files that are clean or ignored or the source of a
       copy/move operation, are not listed unless -c/--clean, -i/--ignored,
       -C/--copies or -A/--all are given. Unless options described with "show
       only ..." are given, the options -mardu are used.
   
       Option -q/--quiet hides untracked (unknown and ignored) files unless
       explicitly requested with -u/--unknown or -i/--ignored.
   
       Note:
          status may appear to disagree with diff if permissions have changed or
          a merge has occurred. The standard diff format does not report
          permission changes and diff only reports changes relative to one merge
          parent.
   
       If one revision is given, it is used as the base revision. If two
       revisions are given, the differences between them are shown. The --change
       option can also be used as a shortcut to list the changed files of a
       revision from its first parent.
   
       The codes used to show the status of files are:
   
         M = modified
         A = added
         R = removed
         C = clean
         ! = missing (deleted by non-hg command, but still tracked)
         ? = not tracked
         I = ignored
           = origin of the previous file (with --copies)
   
       Returns 0 on success.
   
   options ([+] can be repeated):
   
    -A --all                 show status of all files
    -m --modified            show only modified files
    -a --added               show only added files
    -r --removed             show only removed files
    -d --deleted             show only deleted (but tracked) files
    -c --clean               show only files without changes
    -u --unknown             show only unknown (not tracked) files
    -i --ignored             show only ignored files
    -n --no-status           hide status prefix
    -C --copies              show source of copied files
    -0 --print0              end filenames with NUL, for use with xargs

   $ hg help revs
   Specifying Single Revisions
   """""""""""""""""""""""""""
   
       Mercurial supports several ways to specify individual revisions.
   
       A plain integer is treated as a revision number. Negative integers are
       treated as sequential offsets from the tip, with -1 denoting the tip, -2
       denoting the revision prior to the tip, and so forth.
   
       A 40-digit hexadecimal string is treated as a unique revision identifier.
   
       A hexadecimal string less than 40 characters long is treated as a unique
       revision identifier and is referred to as a short-form identifier. A
       short-form identifier is only valid if it is the prefix of exactly one
       full-length identifier.
   
       Any other string is treated as a bookmark, tag, or branch name. A bookmark
       is a movable pointer to a revision. A tag is a permanent name associated
       with a revision. A branch name denotes the tipmost open branch head of
       that branch - or if they are all closed, the tipmost closed head of the
       branch. Bookmark, tag, and branch names must not contain the ":"
       character.
   
       The reserved name "tip" always identifies the most recent revision.
   
       The reserved name "null" indicates the null revision. This is the revision
       of an empty repository, and the parent of revision 0.
   
       The reserved name "." indicates the working directory parent. If no
       working directory is checked out, it is equivalent to null. If an
       uncommitted merge is in progress, "." is the revision of the first parent.
 
+Test repeated config section name
+
+  $ hg help config.host
+      "http_proxy.host"
+          Host name and (optional) port of the proxy server, for example
+          "myproxy:8000".
+  
+      "smtp.host"
+          Host name of mail server, e.g. "mail.example.com".
+  
 Test templating help
 
   $ hg help templating | egrep '(desc|diffstat|firstline|nonempty)  '
       desc          String. The text of the changeset description.
       diffstat      String. Statistics of changes with the following format:
       firstline     Any text. Returns the first line of text.
       nonempty      Any text. Returns '(none)' if the string is empty.

   $ hg help glossary.dag
       DAG
           The repository of changesets of a distributed version control system
           (DVCS) can be described as a directed acyclic graph (DAG), consisting
           of nodes and edges, where nodes correspond to changesets and edges
           imply a parent -> child relation. This graph can be visualized by
           graphical tools such as "hg log --graph". In Mercurial, the DAG is
           limited by the requirement for children to have at most two parents.
   
 
   $ hg help hgrc.paths
       "paths"
       -------
   
       Assigns symbolic names to repositories. The left side is the symbolic
       name, and the right gives the directory or URL that is the location of the
       repository. Default paths can be declared by setting the following
       entries.
   
       "default"
           Directory or URL to use when pulling if no source is specified.
           Default is set to repository from which the current repository was
           cloned.
   
       "default-push"
           Optional. Directory or URL to use when pushing if no destination is
           specified.
   
       Custom paths can be defined by assigning the path to a name that later can
       be used from the command line. Example:
   
         [paths]
         my_path = http://example.com/path
   
       To push to the path defined in "my_path" run the command:

   $ hg help merge-tools
   Merge Tools
   """""""""""
   
       To merge files Mercurial uses merge tools.
   
       A merge tool combines two different versions of a file into a merged file.
       Merge tools are given the two files and the greatest common ancestor of
       the two file versions, so they can determine the changes made on both
       branches.
   
       Merge tools are used both for "hg resolve", "hg merge", "hg update", "hg
       backout" and in several extensions.
   
       Usually, the merge tool tries to automatically reconcile the files by
       combining all non-overlapping changes that occurred separately in the two
       different evolutions of the same initial base file. Furthermore, some
       interactive merge programs make it easier to manually resolve conflicting
       merges, either in a graphical way, or by inserting some conflict markers.
       Mercurial does not include any interactive merge programs but relies on
       external tools for that.
   
       Available merge tools
       =====================
   
       External merge tools and their properties are configured in the merge-
       tools configuration section - see hgrc(5) - but they can often just be
       named by their executable.
   
       A merge tool is generally usable if its executable can be found on the
       system and if it can handle the merge. The executable is found if it is an
       absolute or relative executable path or the name of an application in the
       executable search path. The tool is assumed to be able to handle the merge
       if it can handle symlinks if the file is a symlink, if it can handle
       binary files if the file is binary, and if a GUI is available if the tool
       requires a GUI.
   
       There are some internal merge tools which can be used. The internal merge
       tools are:
   
       ":dump"
         Creates three versions of the files to merge, containing the contents of
         local, other and base. These files can then be used to perform a merge
         manually. If the file to be merged is named "a.txt", these files will
         accordingly be named "a.txt.local", "a.txt.other" and "a.txt.base" and
         they will be placed in the same directory as "a.txt".
   
       ":fail"
         Rather than attempting to merge files that were modified on both
         branches, it marks them as unresolved. The resolve command must be used
         to resolve these conflicts.
   
       ":local"
         Uses the local version of files as the merged version.
   
       ":merge"
         Uses the internal non-interactive simple merge algorithm for merging
         files. It will fail if there are any conflicts and leave markers in the
         partially merged file. Markers will have two sections, one for each side
         of merge.
   
       ":merge3"
         Uses the internal non-interactive simple merge algorithm for merging
         files. It will fail if there are any conflicts and leave markers in the
         partially merged file. Marker will have three sections, one from each
         side of the merge and one for the base content.
   
       ":other"
         Uses the other version of files as the merged version.
   
       ":prompt"
         Asks the user which of the local or the other version to keep as the
         merged version.
   
       ":tagmerge"
         Uses the internal tag merge algorithm (experimental).
   
       ":union"
         Uses the internal non-interactive simple merge algorithm for merging
         files. It will use both left and right sides for conflict regions. No
         markers are inserted.
   
       Internal tools are always available and do not require a GUI but will by
       default not handle symlinks or binary files.
   
       Choosing a merge tool
       =====================
   
       Mercurial uses these rules when deciding which merge tool to use:
   
       1. If a tool has been specified with the --tool option to merge or
          resolve, it is used.  If it is the name of a tool in the merge-tools
          configuration, its configuration is used. Otherwise the specified tool
          must be executable by the shell.
       2. If the "HGMERGE" environment variable is present, its value is used and
          must be executable by the shell.
       3. If the filename of the file to be merged matches any of the patterns in
          the merge-patterns configuration section, the first usable merge tool
          corresponding to a matching pattern is used. Here, binary capabilities
          of the merge tool are not considered.
       4. If ui.merge is set it will be considered next. If the value is not the
          name of a configured tool, the specified value is used and must be
          executable by the shell. Otherwise the named tool is used if it is
          usable.
       5. If any usable merge tools are present in the merge-tools configuration
          section, the one with the highest priority is used.
       6. If a program named "hgmerge" can be found on the system, it is used -
          but it will by default not be used for symlinks and binary files.
       7. If the file to be merged is not binary and is not a symlink, then
          internal ":merge" is used.
       8. The merge of the file fails and must be resolved before commit.
   
       Note:
          After selecting a merge program, Mercurial will by default attempt to
          merge the files using a simple merge algorithm first. Only if it
          doesn't succeed because of conflicting changes Mercurial will actually
          execute the merge program. Whether to use the simple merge algorithm
          first can be controlled by the premerge setting of the merge tool.
          Premerge is enabled by default unless the file is binary or a symlink.
   
       See the merge-tools and ui sections of hgrc(5) for details on the
       configuration of merge tools.

   remove the specified files on the next commit

   <p>
   Schedule the indicated files for removal from the current branch.
   </p>
   <p>
   This command schedules the files to be removed at the next commit.
   To undo a remove before that, see &quot;hg revert&quot;. To undo added
   files, see &quot;hg forget&quot;.
   </p>
   <p>
   -A/--after can be used to remove only files that have already
   been deleted, -f/--force can be used to force deletion, and -Af
   can be used to remove files from the next revision without
   deleting them from the working directory.
   </p>
   <p>
   The following table details the behavior of remove for different
   file states (columns) and option combinations (rows). The file
   states are Added [A], Clean [C], Modified [M] and Missing [!]
   (as reported by &quot;hg status&quot;). The actions are Warn, Remove
   (from branch) and Delete (from disk):

   <h1>Specifying Single Revisions</h1>
   <p>
   Mercurial supports several ways to specify individual revisions.
   </p>
   <p>
   A plain integer is treated as a revision number. Negative integers are
   treated as sequential offsets from the tip, with -1 denoting the tip,
   -2 denoting the revision prior to the tip, and so forth.
   </p>
   <p>
   A 40-digit hexadecimal string is treated as a unique revision
   identifier.
   </p>
   <p>
   A hexadecimal string less than 40 characters long is treated as a
   unique revision identifier and is referred to as a short-form
   identifier. A short-form identifier is only valid if it is the prefix
   of exactly one full-length identifier.
   </p>
   <p>
   Any other string is treated as a bookmark, tag, or branch name. A
   bookmark is a movable pointer to a revision. A tag is a permanent name
   associated with a revision. A branch name denotes the tipmost open branch head
   of that branch - or if they are all closed, the tipmost closed head of the
   branch. Bookmark, tag, and branch names must not contain the &quot;:&quot; character.
   </p>
   <p>
   The reserved name &quot;tip&quot; always identifies the most recent revision.
   </p>
   <p>
   The reserved name &quot;null&quot; indicates the null revision. This is the
   revision of an empty repository, and the parent of revision 0.
   </p>
   <p>
   The reserved name &quot;.&quot; indicates the working directory parent. If no
   working directory is checked out, it is equivalent to null. If an
   uncommitted merge is in progress, &quot;.&quot; is the revision of the first
   parent.
