<h2><a href="http://darcs.net/">Darcs</a></h2>

<p>Darcs is a distributed revision control system written in Haskell. In

Darcs, every copy of your source code is a full repository, which allows for

full operation in a disconnected environment, and also allows anyone with

read access to a Darcs repository to easily create their own branch and

modify it with the full power of Darcs' revision control. Darcs is based on

an underlying theory of patches, which allows for safe reordering and

merging of patches even in complex scenarios. For all its power, Darcs

remains a very easy to use tool for every day use because it follows the

principle of keeping simple things simple.  Darcs is free software

licensed under the GNU GPL.</p>

library materials, and sharing resources among groups of libraries and

consortia on the same Evergreen system.  Evergreen is designed to be

scalable and supports library operations ranging from a small high school

to large state-wide consortia.  Evergreen is released under
