"""
Goal: Create a UFOZ automatically when a UFO is saved.

Off the top of my head, I can think of a few ways to do this:

1. Make a copy of the font object, save as UFOZ, discard the
   copied object.
2. Save the UFO, save the same font object to UFOZ, switch
   the path of the font object back to the UFO path.
3. Make a zip of the written UFO.

The third seems like it will be the most efficient, so I'm
going to use that. I'm too lazy to actually test all the
different methods, but someone could.
