Especially when you consider that you now have 3 CVSROOTs to talk about on the 
mailing list
$CVSROOT #environment var pointing to repository
$CVSROOT/CVSROOT/ # repository config files
$CVSROOT/../CVSROOT/ # repository

It's always been fun trying to figure out what folks were talking about on the 
mailing list with
just the first two.

(just so I know)
are you saying 1.11.23 triggers the message?
The example I gave worked with 1.11.22, with out any messages.
