That sounds good. I see your point about just trying to get number of
them, and not necessarily trying to get them all. If it works out well,
you might be able to refine the process to get more later, as well as
filling in the blanks by hand.
So far it sounds like you have a good handle on this. When you get some
outputs, send them my way and I will get the modules onto the build server!
