Mussa - Darcs Revision Control System

What is Darcs?

To quote the ​darcs web site:

Darcs is a revision control system. Darcs is simple to learn and use,
with a powerful new approach to meet the needs of today's distributed
software projects. Darcs is decentralized, based on a "theory of
patches" with roots in quantum mechanics.
