ACL status

[Rafael Sanz]

Hello, I need to extend my cvs server with fine grain of Access Control
Level (beyond writers or readers files natives in CVS standar).

I'm found some references to patches at C code
(http://www.unixgods.org/~tilo/CVS_ACL/), but any is standard...

What is the develop status of ACL in cvs server for UNIX?? Is in progress?
Nothing about?

Whatever, some link better to ACL solutions that deal with read restriction
for files or directories?

Thanks in advanced.
