darcs

Darcs is an advanced revision control system, for source code or other files. It is fully distributed, and supports lazy fetching of the remote repository (fetching only what is needed at the time, rather than all history). It works best with text files, but it can also store binary files.

Darcs is a free, open source source code management system.

Distributed Every user has access to the full command set, removing boundaries between server and client or committer and non-committers. Interactive Darcs is easy to learn and efficient to use because it asks you questions in response to simple commands, giving you choices in your work flow. You can choose to record one change in a file, while ignoring another. As you update from upstream, you can review each patch name, even the full "diff" for interesting patches. Smart Originally developed by physicist David Roundy, darcs is based on a unique algebra of patches. This smartness lets you respond to changing demands in ways that would otherwise not be possible. For example, learn about spontaneous branches with darcs.
