In that case, you will almost certainly get more mileage if you consult
a list that specializes in CVSNT. Most of the folk here are familiar
with the vanilla CVS product.

For CVSNT support, have a look here:

For CVS, yes, and the manual bears that out:
http://ximbiot.com/cvs/manual/cvs-1.11.21/cvs_18.html#SEC172

Can't say about CVSNT, though.

Now you're getting into vbscript questions. I don't know if anyone here
can help you with that (I know nothing about vbscript and I hope to keep
it that way ;-)

Why not try writing the script in Perl?

By the way, have you considered how to stop people entering 'asdf' or
other random strings as a commit message?
