Mercurial is a (distributed) version control system. Home of mercurial is: http://www.selenic.com/mercurial/wiki/
I'm currently trying out mercurial. Main advantage of mercurial compared to subversion (from my point of view) is primary it's design: distributed version control. You don't depend on an central vcs-server as you do with subversion.
An comprehensive manual can be found at http://hgbook.red-bean.com/
aptitude install mercurial

hgext.keyword=
# filename patterns for expansion are configured in this section
[keyword]
# expand keywords in all puppet *.pp files in working dir
**.pp =
# do not expand keywords in files matching "x*" in working dir
#x* = ignore
# override the cvs-like default mappings with customized keyword = expansion pairs,
# where expansion values contain Mercurial templates and filters
[keywordmaps]
Id = {file|basename} {rev}:{node|short} {date|utcdate} {author|user}
To crosscheck which files in your working directory are matched by the current [keyword] patterns, use ”hg kwfiles”.
Run ”hg kwshrink” before changing or disabling currently active keywords.
Run ”hg kwexpand” to force expansion in the working directory after enabling it, or after a keyword configuration change.
