Information:
CVS, Concurrent Versions System, is a command-line program that allows you to manage ASCII files that can be changed by different users on a network.
The applications are ASCII text-based files that were developed by multiple programmers working independently.
Typically, CVS is installed at one computer that acts as CVS-server and a couple of others that are CVS clients.
The functionality of the CVS server includes the storage of the current versions, the merge of changes to the last version and the synchronization of the server modules with those modules that are actually present at the different local sites of each programmer.
