Are you sure about that? You can certainly use a bat file as a hook
script (I do at work) and I'm note sure why one bat would not be able
to start another.

However, the environment for a server side hook script will not know
anything about the WC location. Until TSVN 1.5 come out you will have
to run your script manually.

Also, I believe the syntax of your batch file is wrong. Try 'if exist'
instead of 'if exists'.

The fact that your script does nothing only indicates that nothing has
changed since you last ran it. SubWCRev deliberately does not write to
the output file if the content would be unchanged.

And finally, if you run SubWCRev as a pre-commit hook script, it will
get revision numbers as they were *before* the commit which may not be
very useful.
