I use cruisecontrol.rb for CI and FogBugz for bug tracking, but the more general the answers, the better.
First is the technical problem: is there an API for FogBugz? Are there good tutorials, or better yet, pre-written code?
Second is the procedural problem: what, exactly, should the CI put in the bug tracker when the build breaks? Perhaps:
Title: "#{last committer} broke the build!"
Body: "#{ error traces }"
I suppose this presupposes the answer to this question: should I even put CI breaks into my bug tracking?
