darcs-2.5.2: a distributed, interactive, smart revision control system

Darcs is a free, open source revision control system. It is:

• 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. Learn more about spontaneous branches with darcs.
