CVS: Questions for clarification

[Laxma Poreddy]

Larry,

Thanks for your quick response.  But I got a question about lock on branch and 
its limitations.

Can I provide access to very limited users on any branch in CVS?
In other words, I would like to lock a branch and give access to very limited 
users?
If so, how can we do it?

Thanks,
Laxma
