CVS is the Concurrent Versions System, the dominant open-source network-transparent version control system. CVS is useful for everyone from individual developers to large, distributed teams:

• Its client-server access method lets developers access the latest code from anywhere there's an Internet connection.
• Its unreserved check-out model to version control avoids artificial conflicts common with the exclusive check-out model.
• Its client tools are available on most platforms.
