Tagging files

[Amit Sharma]

Hi all,
        AFAIK In CVS all users's log entries goes to history files in
CVSROOT but I want that although users can add to history but they should
not be able to tag the files as in my case All the users are able to tag the
files but I need Admin can tag the code and other Admin stuff like Branching
etc as well and not all users

P.S.: If i make the history file read only then users can't log history to
history file.

Please help

Thanks & Regrads,
Amit Sharma
