Darcs is a distributed revision control system by David Roundy that was designed to replace traditional centralized source control systems such as CVS and subversion. Two particular features in its design distinguish it from CVS. Each copy of the source tree acts as a full repository, allowing several different versions to be maintained in different locations. Patches are global to the repository and are subject under certain conditions to reordering, as governed by the project's theory of patches.The name is an acronym for David's Advanced Revision Control System, but is usually spelled lowercase (darcs), except at the beginning of sentences.In basic usage, users get a copy of a repository, make any changes, record the changes, pull changes from other repositories, and finally push or send changes to other repositories. To start a new repository, users can init any directory.Other repositories can be local directories, or accessed by SSH or HTTP protocols. Changes can be submitted by email in situations where the user lacks permission to write to another repository.Darcs is written in the functional programming language Haskell; among other tools, it uses QuickCheck.Many of its commands are interactive, allowing users to commit changes or pull specific files selectively. This feature is designed to encourage more specificity in patches. As a result of this interactivity, darcs has fewer distinct commands than many comparable revision control systems.  [edit]  Less
