Are they really Eagle footprints?  I don't think so.  I think they are footprints
generated by executing a scriplet in the eagle scripting language, which you intend to be
able to "execute" using python, correct?

True eagle footprints are actually now in XML format.  To read those you would simply fill
out EAGLE_PLUGIN::FootprintLoad().
