 # 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".
 
 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.
