cvs diff on repository

[aaron . brice]

I'm wanting to set CVS up so that every time a file is committed it will
send an email with the diffs to the other developers for code review.

I added a line to the loginfo file:

DEFAULT $CVSROOT/CVSROOT/cvsdiff.pl %{sVv}

cvsdiff.pl is a script that does a cvs diff of the two versions and
emails the results.  However, a cvs diff does not work on the repository
files (",v"), it complains about missing CVS/Entries.  Is there a way to
get the diff of two different versions of a file from the repository?  I
noticed that the contrib/log.pl script is meant to be run from loginfo
and does a cvs status, which also fails for me from the repository.

Thanks for any help.  I emailed a similar question yesterday before I
subscribed and got a reply saying that it's waiting for moderator
approval, so apologies if I end up posting this twice..
