Description:

Trac is a minimalistic web-based software project management and
bug/issue tracking system. It provides an interface to revision
control systems (Subversion), an integrated Wiki and convenient
report facilities.

Trac allows wiki markup in issue descriptions and commit messages,
to create links and seamless references between bugs, tasks,
changesets, files and wiki pages. A timeline shows all project
events in order, making getting an overview of the project and
tracking progress very easy.
