Trac is an enhanced wiki and issue tracking system for software development projects. Trac uses a minimalistic approach to web-based software project management. It strives 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.
It provides an interface to Subversion (and other version control systems), an integrated Wiki and convenient reporting facilities.
Trac allows wiki markup in issue descriptions and commit messages, creating links and seamless references between bugs, tasks, changesets, files and wiki pages. A timeline shows all current and past project events in order, making the acquisition of an overview of the project and tracking progress very easy. The roadmap shows the road ahead, listing the upcoming milestones.
If you are looking for a good place to ask a question about Trac, look no further than the MailingList. It provides a friendly environment to discuss openly among Trac users and developers.
