About access control.(use cvs_acls)

[xiangbin]

Hi,all
I use the perl script "cvs_acls"(in cvs source release contrib/) to control
the access for special user and it works fine .
Now I need to control the access for add && destory.One  may only has add
access and no destroy access.
Anyone knows how can I achieve this?

Also,when I use cvs_acls script for access control,every time when I do
"commit",it gives me this warnings:
-----------------------------------------------------------------------
cvs commit: warning: commitinfo line contains no format strings:
    "/usr/local/cvsrep/CVSROOT/commit_prep"
Appending defaults (" %r/%p %s"), but please be aware that this usage is
deprecated.
cvs commit: warning: commitinfo line contains no format strings:
    "/usr/local/cvsrep/CVSROOT/cvs_acls  -u xiangbin "
Appending defaults (" %r/%p %s"), but please be aware that this usage is
deprecated.
----------------------------------------------------------------
I really do not want to see this.If there is some way to swith this warning
off ?
