I have attached the script for reference. It is based on the
commit-email.pl file. It is unfinished and full of debug output, I
don't recommend actually using this script.
Looking over it again, I remember better why I abandoned the idea.
Since you can't do a propset on a URL, I have to do a temporary checkout
to set properties. I do a full checkout/propset/commit for each file
that needs to have its properties updated, even if all the files are in
the same directory.
