keyword extension - 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 repositories.

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.

list of commands:

 kwdemo     print [keywordmaps] configuration and an expansion example
 kwexpand   expand keywords in working directory
 kwfiles    print files currently configured for keyword expansion
 kwshrink   revert expanded keywords in working directory

enabled extensions:

 keyword   keyword expansion in local repositories
 mq        patch management and development
 notify    hook extension to email notifications on commits/pushes

use "hg -v help keyword" to show aliases and global options
