+'''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>!
