Limiting access

[Robert S. Sfeir]

Ok now that's I've got about 6 different modules imported in CVS, I have 5 
contractors and only want them to access certain modules, some should have 
the ability to check them out and edit files, others just check out and 
look, but don't touch.

Is there a way to do this?  We all use Win/MacCVS and don't do much from 
the command line.
