This is a work contributed by the great Mr. Sorenson; to keep
it easy to find, I'm going to keep a copy up on the website here.
Bear in mind that you must have both OmniOutliner3 Professional AND
Shadow Desktop 4.1 for this to work.

In case his site is down, I've mirrored a copy of the stuff here; this
could very well be out of date, so check his site first!
