The Distributed CVS extends the well-known version control system CVS and the file distribution and synchronization program CVSup with functionality to distribute CVS repositories with local lines of development. DCVS handles synchronization of the distributed repositories automatically in the background. Development lines (branches) are be owned by a repository server, repository servers are efficiently updating each other via CVSup, and CVS will ensure correct server use on checkin and branch creation. The functionalities of snapshots and change sets provide powerful means for release and change management. The code is freely distributable under the GNU and BSD style licenses (for the CVS and CVSup part, respectively). The project homepage offers options to download DCVS source and binary packages, access to release notes, bug reporting and further information.
