No. But for tracking module review, Bugzilla might be better than the wiki. It allows us to have a conversation on each module via comments. >> But it is not really a sufficient solution. Why?

Every developer applies their own criteria. It is not reproducible. It leaves no audit trail. And it doesn't help us with the next release. If you use the Apache Release Audit Tool (RAT) then it will check all the files automatically. > And how to make sure that there was no change when source was > added/moved/improved?

You can think of this as a form of CTR, but one that is automated, with a consistent rule set. Obviously, good CTR plus the work on the wiki will all help. But we need the RAT scans as well, to show that we're clean. > BTW: > What is your plan to track every file to make sure the license is OK? > Run RAT.
