Hi I have a networked environment with my box having linux in India.

I have a centralized server which has CVS on it. The development team
is spread across USA and India.I am required to synchronize CVS over
here with one in USA. I have rsync installed on the server. With
rsyncing I am able to pass over my copy of CVS to USA with no hitch.
There the team gets it, updates it thereby getting all the changes
originated from India. Now when they(USA) do certain kinds of changes
in their CVS copy, how can I receive those changes without my changes
getting erased over.

Is it possible? Is it possible with Rsync?? Also I have read about
CVSup. Is it possible with CVSup??

Plz help me out get over this. This is really urgent.
Thanks.
