-'''expand expressions into changelog and summaries
-
-This extension allows the use of a special syntax in summaries, which
-will be automatically expanded into links or any other arbitrary
-expression, much like InterWiki does.
-
-A few example patterns (link to bug tracking, etc.) that may be used
-in your hgrc::
-
-  [interhg]
-  issues = s!issue(\\d+)!<a href="http://bts/issue\\1">issue\\1</a>!
-  bugzilla = s!((?:bug|b=|(?=#?\\d{4,}))(?:\\s*#?)(\\d+))!<a..=\\2">\\1</a>!i
-  boldify = s!(^|\\s)#(\\d+)\\b! <b>#\\2</b>!
