A Concurrent Versions System (CVS) repository will provide your developers network-transparent source control for groups of developers. You can use your CVS repository from the server's command line or from your remote workstation.

We'll work with you to set up the CVS user accounts you need, and we'll set up read-only or read-write permissions for each account. We'll also give you the pathnames and an example connection string so you can start managing your code base right away!

You can find more information about CVS at the CVS Wikipedia page.
