cvs server?

[Patrick Guio]

Dear all,

I try to find some documentation about how to set up and use the
'cvs server' command but I cannot find that much.
I would like to use it with ssh forced command.

Shall the '--allow-root=' option point to a $CVSROOT or can it 
directly point to a project within a $CVSROOT?
In other words does it need access to $CVSROOT/CVSROOT?
If so how do I restrict r/w access to only one of my project when 
accessed from a special ip?

Sincerely,
Patrick
