        Oh, didn't know that!

        Excellent, thanks!!

        That's only going to work for old-style Mac OS fonts - it
won't work for any of the new formats (.dfont, .ttf, .otf, etc.) that
are supported by Mac OS X (I don't know if that's an issue for you or
now).   As such, I've written the following code that deal with the
different types of fonts...

        Hope it helps!
