Bug track tools

[David chen]

Trac is an enhanced wiki and issue tracking system for software
development projects. Trac uses a minimalistic approach to web-based
software project management. Our mission is to help developers write
great software while staying out of the way. Trac should impose as
little as possible on a team's established development process and
policies.
