That's what I want, but it has to allow for a specific path to get
around having to specifically add the zip utility on Windows to the
actual $PATH environment. I'd rather leave the switches along, as then
one doesn't have to figure out a bunch of other zip utility stuff.

The current documentation requires that one have a *nix-equivalent
(wrt syntax) zip utility, hence other mailing list suggestions to use
INFO-zip.

If we want to go another route, say allowing for 7zip, it would
require more more cases to check for the actual zip utility being
used. INFO-zip was simple enough, so I think it would be fair to have
the user download it, move zip.exe somewhere, and then point to it
with the variable.

I'll keep thinking through it. For now, I got Windows working by
simply editing ox-odt directly and replacing zip with zip.exe :)
