Trac is an open source, web-based project management and bug-tracking tool. The program is inspired by CVSTrac, and was originally named svntrac due to its ability to interface with Subversion.
Trac allows hyperlinking information between a bug database, revision control and wiki content. It also serves as a web interface to the following revision control systems: Subversion, Git, Mercurial, Bazaar, Perforce and Darcs.
Other features include:
