Concurrent Versions System (CVS) is a free version control system. CVS enables multiple developers to work on a common code base without overwriting each other's changes. The history of the files, including the date and author of the changes, are stored in a CVS repository. Files are not edited directly in the repository. A developer can check out the code from the repository into a CVS working directory, edit the code there, and check the changes back into the repository. There are CVS commands for adding and removing files from the repository, updating the working directory to incorporate changes made by others in the repository, and comparing differences between versions of a file.
The IDE's CVS module enables you to mount a CVS working directory as a filesystem and call CVS commands from within the IDE.
CVS itself is not part of the IDE. To use the CVS module, you must first download and install CVS on your system.
It is available for free from the GNU web site at http://www.gnu.org/
and other sites.
