Concurrent Versions System (CVS, or Concurrent Versioning System) is a version control system originally developed by Dick Grune in July 1986. It builds on top of an older version control system called Revision Control System (RCS), adding support for repository-level change tracking, and a client-server model. CVS servers normally run on Unix systems, while clients can be on any operating system.
