 '''track a line of development with movable markers
 
 Bookmarks are local movable markers to changesets. Every bookmark
 points to a changeset identified by its hash. If you commit a
 changeset that is based on a changeset that has a bookmark on it, the
 bookmark shifts to the new changeset.
 
 It is possible to use bookmark names in every revision lookup (e.g.
 :hg:`merge`, :hg:`update`).
 
 By default, when several bookmarks point to the same changeset, they
 will all move forward together. It is possible to obtain a more
 git-like experience by adding the following configuration option to
 your .hgrc::
 
   [bookmarks]
   track.current = True
 
 This will cause Mercurial to track the bookmark that you are currently
 using, and only update it. This is similar to git's approach to
 branching.

     Bookmarks are pointers to certain commits that move when
     committing. Bookmarks are local. They can be renamed, copied and
     deleted. It is possible to use bookmark names in :hg:`merge` and
     :hg:`update` to merge and update respectively to a given bookmark.
 
     You can use :hg:`bookmark NAME` to set a bookmark on the working
     directory's parent revision with the given name. If you specify
     a revision using -r REV (where REV may be an existing bookmark),
     the bookmark is assigned to that revision.

 # keyword.py - $Keyword$ expansion for Mercurial

 #
 # Keyword expansion hack against the grain of a DSCM
 #
 # There are many good reasons why this is not needed in a distributed
 # SCM, still it may be useful in very small projects based on single
 # files (like LaTeX packages), that are mostly addressed to an
 # audience not running a version control system.
 #
 # For in-depth discussion refer to
 # <http://mercurial.selenic.com/wiki/KeywordPlan>.
 #
 # Keyword expansion is based on Mercurial's changeset template mappings.
 #
 # Binary files are not touched.
 #
 # Files to act upon/ignore are specified in the [keyword] section.
 # Customized keyword template mappings in the [keywordmaps] section.
 #
 # Run "hg help keyword" and "hg kwdemo" to get info on configuration.
 
 '''expand keywords in tracked files
 
 This extension expands RCS/CVS-like or self-customized $Keywords$ in
 tracked text files selected by your configuration.
 
 Keywords are only expanded in local repositories and not stored in the
 change history. The mechanism can be regarded as a convenience for the
 current user or for archive distribution.
 
 Configuration is done in the [keyword], [keywordset] and [keywordmaps]
 sections of hgrc files.
 
 Example::
 
     [keyword]
     # expand keywords in every python file except those matching "x*"
     **.py =
     x*    = ignore
 
     [keywordset]
     # prefer svn- over cvs-like default keywordmaps
     svn = True
 
 NOTE: the more specific you are in your filename patterns the less you
 lose speed in huge repositories.
 
 For [keywordmaps] template mapping and expansion demonstration and
 control run :hg:`kwdemo`. See :hg:`help templates` for a list of
 available templates and filters.
 
 Three additional date template filters are provided::
 
     utcdate      "2006/09/18 15:13:13"
     svnutcdate   "2006-09-18 15:13:13Z"
     svnisodate   "2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
 
 The default template mappings (view with :hg:`kwdemo -d`) can be
 replaced with customized keywords and templates. Again, run
 :hg:`kwdemo` to control the results of your config changes.
 
 Before changing/disabling active keywords, run :hg:`kwshrink` to avoid
 the risk of inadvertently storing expanded keywords in the change
 history.
 
 To force expansion after enabling it, or a configuration change, run
 :hg:`kwexpand`.
 
 Expansions spanning more than one line and incremental expansions,
 like CVS' $Log$, are not supported. A keyword template map "Log =
 {desc}" expands to the first line of the changeset description.

 '''manage a stack of patches
 
 This extension lets you work with a stack of patches in a Mercurial
 repository. It manages two stacks of patches - all known patches, and
 applied patches (subset of known patches).
 
 Known patches are represented as patch files in the .hg/patches
 directory. Applied patches are both patch files and changesets.
 
 Common tasks (use :hg:`help command` for more details)::
 
   create new patch                          qnew
   import existing patch                     qimport
 
   print patch series                        qseries
   print applied patches                     qapplied
 
   add known patch to applied stack          qpush
   remove patch from applied stack           qpop
   refresh contents of top applied patch     qrefresh
 
 By default, mq will automatically use git patches when required to
 avoid losing file mode changes, copy records, binary files or empty
 files creations or deletions. This behaviour can be configured with::
 
   [mq]
   git = auto/keep/yes/no
 
 If set to 'keep', mq will obey the [diff] section configuration while
 preserving existing git patches upon qrefresh. If set to 'yes' or
 'no', mq will override the [diff] section and always generate git or
 regular patches, possibly losing data in the second case.
 
 You will by default be managing a patch queue named "patches". You can
 create other, independent patch queues with the :hg:`qqueue` command.

     When no guards are active, patches with positive guards are
     skipped and patches with negative guards are pushed.

     To create a new queue, use -c/--create. The queue is automatically made
     active, except in the case where there are applied patches from the
     currently active queue in the repository. Then the queue will only be
     created and switching will fail.
 
     To delete an existing queue, use --delete. You cannot delete the currently
     active queue.

     The location of the source is added to the new repository's
     .hg/hgrc file, as the default to be used for future pulls.
 
     See :hg:`help urls` for valid source format details.
 
     It is possible to specify an ``ssh://`` URL as the destination, but no
     .hg/hgrc and working directory will be created on the remote side.
     Please see :hg:`help urls` for important details about ``ssh://`` URLs.
 
     A set of changesets (tags, or branch names) to pull may be specified
     by listing each changeset (tag, or branch name) with -r/--rev.
     If -r/--rev is used, the cloned repository will contain only a subset
     of the changesets of the source repository. Only the set of changesets
     defined by all -r/--rev options (including all their ancestors)
     will be pulled into the destination repository.
     No subsequent changesets (including subsequent tags) will be present
     in the destination.
 
     Using -r/--rev (or 'clone src#rev dest') implies --pull, even for
     local source repositories.
 
     For efficiency, hardlinks are used for cloning whenever the source
     and destination are on the same filesystem (note this applies only
     to the repository data, not to the working directory). Some
     filesystems, such as AFS, implement hardlinking incorrectly, but
     do not report errors. In these cases, use the --pull option to
     avoid hardlinking.
 
     In some cases, you can clone repositories and the working directory
     using full hardlinks with ::
 
       $ cp -al REPO REPOCLONE
 
     This is the fastest way to clone, but it is not always safe. The
     operation is not atomic (making sure REPO is not modified during
     the operation is up to you) and you have to make sure your editor
     breaks hardlinks (Emacs and most Linux Kernel tools do so). Also,
     this is not compatible with certain extensions that place their
     metadata under the .hg directory, such as mq.
 
     Mercurial will update the working directory to the first applicable
     revision from this list:
 
     a) null if -U or the source repository has no changesets
     b) if -u . and the source repository is local, the first parent of
        the source repository's working directory
     c) the changeset specified with -u (if a branch name, this means the
        latest head of that branch)
     d) the changeset specified with -r

     You can import a patch straight from a mail message. Even patches
     as attachments work (to use the body part, it must have type

     message are used as default committer and commit message. All

     If the imported patch was generated by :hg:`export`, user and
     description from patch override values from message headers and
     body. Values given on command line with -m/--message and -u/--user
     override these.
 
     If --exact is specified, import will set the working directory to
     the parent of each patch before applying it, and will abort if the
     resulting changeset has a different ID than the one recorded in
     the patch. This may happen due to character set problems or other
     deficiencies in the text patch format.
 
     With -s/--similarity, hg will attempt to discover renames and

     the working directory parents. Use :hg:`update -r rev` to check out earlier
     revisions, or :hg:`update --clean .` to undo a merge which has added
     another parent.
 
     With no revision specified, revert the named files or directories
     to the contents they had in the parent of the working directory.
     This restores the contents of the affected files to an unmodified
     state and unschedules adds, removes, copies, and renames. If the
     working directory has two parents, you must explicitly specify a
     revision.
 
     Using the -r/--rev option, revert the given files or directories
     to their contents as of a specific revision. This can be helpful
     to "roll back" some or all of an earlier change. See :hg:`help
     dates` for a list of formats valid for -d/--date.
 
     Revert modifies the working directory. It does not commit any
     changes, or change the parent of the working directory. If you
     revert to a revision other than the parent of the working
     directory, the reverted files will thus appear modified
     afterwards.
 
     If a file has been deleted, it is restored. If the executable mode
     of a file was changed, it is reset.
 
     If names are given, all files matching the names are reverted.
     If no arguments are given, no files are reverted.

     This command should be used with care. There is only one level of
     rollback, and there is no way to undo a rollback. It will also
     restore the dirstate at the time of the last transaction, losing
     any dirstate changes since that time. This command does not alter
     the working directory.
 
     Transactions are used to encapsulate the effects of all commands
     that create new changesets or propagate existing changesets into a
     repository. For example, the following commands are transactional,
     and their effects can be rolled back:
 
     - commit
     - import
     - pull
     - push (with this repository as the destination)
     - unbundle
 
     This command is not intended for use on public repositories. Once
     changes are visible for pull by other users, rolling a transaction
     back locally is ineffective (someone else may already have pulled
     the changes). Furthermore, a race is possible with readers of the
     repository; for example an in-progress pull from the repository
     may fail if a rollback is performed.

     longer periods of time.

     should use a real web server if you need to authenticate users.

     files.

 mq extension - manage a stack of patches
 
 This extension lets you work with a stack of patches in a Mercurial
 repository. It manages two stacks of patches - all known patches, and applied
 patches (subset of known patches).
 
 Known patches are represented as patch files in the .hg/patches directory.
 Applied patches are both patch files and changesets.
 
 Common tasks (use "hg help command" for more details):
 
   create new patch                          qnew
   import existing patch                     qimport
 
   print patch series                        qseries
   print applied patches                     qapplied
 
   add known patch to applied stack          qpush
   remove patch from applied stack           qpop
   refresh contents of top applied patch     qrefresh
 
 By default, mq will automatically use git patches when required to avoid
 losing file mode changes, copy records, binary files or empty files creations
 or deletions. This behaviour can be configured with:
 
   [mq]
   git = auto/keep/yes/no
 
 If set to 'keep', mq will obey the [diff] section configuration while
 preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq
 will override the [diff] section and always generate git or regular patches,
 possibly losing data in the second case.
 
 You will by default be managing a patch queue named "patches". You can create
 other, independent patch queues with the "hg qqueue" command.
 
 list of commands:
 
  qapplied     print the patches already applied
  qclone       clone main and patch repository at same time
  qdelete      remove patches from queue
  qdiff        diff of the current patch and subsequent modifications
  qfinish      move applied patches into repository history
  qfold        fold the named patches into the current patch
  qgoto        push or pop patches until named patch is at top of stack
  qguard       set or print guards for a patch
  qheader      print the header of the topmost or specified patch
  qimport      import a patch
  qnew         create a new patch
  qnext        print the name of the next patch
  qpop         pop the current patch off the stack
  qprev        print the name of the previous patch
  qpush        push the next patch onto the stack
  qqueue       manage multiple patch queues
  qrefresh     update the current patch
  qrename      rename a patch
  qselect      set or print guarded patches to push
  qseries      print the entire series file
  qtop         print the name of the current patch
  qunapplied   print the patches not yet applied
  strip        strip a changeset and all its descendants from the repository
