Darcs - Distributed Revision Control in Haskell

Darcs is a distributed advanced revision control system written in Haskell. It is similar to Git, Mercurial and Bazaar. User will have own personnel repository and commits his changes to it. Later the changes are pushed to the centralized repository. Every repository is a branch and it provides support to integrate the changes between them. It provides support to send the changes by email.

The fundamental difference is that Git, Mercurial and Bazaar maintains a chronological order in the changes of the repository. Darcs manipulates patches instead of chronological revisions, so darcs maintains a more fine-grained order on changes, that could be called patches dependencies.
