Cvs?
 

What is the purpose of CVS in LINUX?

Thanks

CVS is Concurrent Version System, it is to have a place to keep updated files. If you want the most bleeding edge version of something, CVS is where to go.
Here is the CVS homepage. You can read all about it there.

Here's a quote from their website:
"This site is dedicated to supporting the community around CVS.

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. "

Any free cvs servers available for personal use?

Do you actually mean for development? Or do you want a place to store your files?

Yes, just to store my files but in the cvs manner.

CVS is GPLed. Also most of the clients, utilities etc.
