 # 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://www.selenic.com/mercurial/wiki/index.cgi/KeywordPlan>.
 #
 # Keyword expansion is based on Mercurial's changeset template mappings.
 #
 # Binary files are not touched.
 #
 # Setup in hgrc:
 #
 #   [extensions]
 #   # enable extension
 #   hgext.keyword =
 #
 # 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.
 
 '''keyword expansion in local repositories
 
 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] and [keywordmaps] sections
 of hgrc files.
 
 Example:
 
     [keyword]
     # expand keywords in every python file except those matching "x*"
     **.py =
     x*    = ignore
 
 Note: the more specific you are in your filename patterns
       the less you lose speed in huge repos.
 
 For [keywordmaps] template mapping and expansion demonstration and
 control run "hg kwdemo".
 
 An additional date template filter {date|utcdate} is provided.
 
 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 inadvertedly storing expanded keywords in the change history.
 
 To force expansion after enabling it, or a configuration change, run
 "hg kwexpand".
 
 Also, when committing with the record extension or using mq's qrecord, be aware
 that keywords cannot be updated. Again, run "hg kwexpand" on the files in
 question to update keyword expansions after all changes have been checked in.
 
 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.
