For future reference (and eventual installation): CVSTrac, a Web-based bug tracking application that integrates with CVS. It’s free and uses a file-based database system for easy backup.
[UPDATE (8/12/03): I installed it and it exceeded my expectations beyond what I could have imagined. Where I couldn’t get Bugzilla to work on my laptop, I couldn’t believe how simple this one was to install. And the features! Oh the features! Check out a live example at cvs.cvstrac.org and click around, especially the timeline. Open source never ceases to astound me.]
