I'm looking for an integrated solution that combines documentation of a software system with tracking of bugs, change requests and feature requests.
- Documentation using a wiki would be nice, preferably one supporting CamelCase or other automatic linking.
- Issue tracking must allow a customizable workflow and optional e-mail notifications.
- FogBugz is an awesome issue tracker, but the wiki appears to be somewhat awkward.
- Trac's wiki is average (though not as nice as Foswiki.org) but I don't know how good the integrated issue tracker is.
What would you recommend? What systems offer the best combination of documentation and issue tracking?
