2014-11-05 11:30 AEST by Arthur Barrett - In theory each directory of a sandbox can have a different CVS/Root - i.e.: a different server and/or 
repository.

Commands such as 'commit' will traverse the servers automatically (but you will end up with multiple 
commit id's, even if the 'names' resolve to the one server).

However this doesn't work with 'cvs diff':

C:\Users\UD6_Sales\userdlls>cvs diff -c announce\announce.c ud6\extend

In this case announce is:

and ud6/extend is:
