Concurrent Versions System

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Concurrent Versions System (CVS), also known as the Concurrent Versioning System, is a free software revision control system in the field of software development. Version control system software keeps track of all work and all changes in a set of files, and allows several developers (potentially widely separated in space and/or time) to collaborate. Dick Grune developed CVS as a series of shell scripts in July 1986. CVS became popular in the open source software world and is released under the GNU General Public License. In the early 2000s, many users of CVS began to replace it with Subversion, which was explicitly designed to be "a better CVS" and to circumvent some of its limitations. As of January 2009, many open source projects had, in turn, replaced Subversion or CVS with a distributed version control system, such as Git, Mercurial or Bazaar.
