The link didn't seem to work so well, but this is essentially what I wound up doing, although I used perl instead of windows batch. It works, but I worry that it will break too easily. Still, it allows a clueless user to get the program up and running with minimal hassle.

Cava packager seems like a good solution too, but I haven't quite figured out the right tweaks to get the result I want. I am playing with it more, in hopes that it will be the ultimate solution.

Thanks to all those who helped.
