The problem here is, some footprint generators have a lot of parameters, 
e.g. for pin and pad sizes, silk line width, pin row/column distance, etc. 
With my "arthropods" generator, I found what's really necessary is a kind 
of "configuration" file which holds the parameters for one or some related 
series of footprints (see [0] for an example).
