CVS dir permissions

[Chris Croswhite]

Hello,

I have been digging into the manual for security and directory permissions.  So 
far I have not found what I am looking to implement and that is to cut off 
others outside specific groups from seeing the cvs repository.  Currently I 
must maintain 755 on all the dirs inorder for cvs to work.  If I change to 750, 
even someone with the same group membership, cvs will not run properly.

I need to know how to implement simple dir permissions to cut off the outside 
world e.g. 750.  Any help is greatly appreciated.

TIA,
Chris
