Bugs Everywhere is a “distributed bug tracker”, designed to complement a distributed version control system (VCS). By using a distributed VCS as a back-end for bug state, it gains several convenient features:

* Bugs and code that live on branches are tracked together.
* Users can fully modify bug state while offline.
* When a user checks out a project’s source code, she gets the current
bug state for free.
* A web interface to the bug database becomes just another client that
merges with the main repository.
Bugs Everywhere currently supports the following VCS back-ends:

* GNU Arch (tla, baz)
* Bazaar (bzr)
* git
* Mercurial (hg)
* Darcs
* Monotone (mtn)
* GNU RCS
