multiple repositories on a single cvs port

A Rockville, MD group has a lot of repositories in their CVS directory. To give each one its own port would be (and was) absurd. So I set up a single entry with 9 --allow-root=dir entries

upon telnet to localhost 2911;

The Concurrent Versions System (CVS) is a tool for version control.
For CVS updates and additional information, see
the CVS home page at http://www.cvshome.org/ or
Pascal Molli's CVS site at http://www.loria.fr/~molli/cvs-index.html

The manual states:

The `--allow-root' option specifies the allowable CVSROOT directory. Clients which attempt to use a different CVSROOT directory will not be allowed to connect. If there is more than one CVSROOT directory which you want to allow, repeat the option. (Unfortunately, many versions of inetd have very small limits on the number of arguments and/or the total length of the command. The usual solution to this problem is to have inetd run a shell script which then invokes CVS with the necessary arguments.)
