Also, the path most people take w.r.t. defining similar footprint sets
is to use scripts or programs to generate families of footprint files
all at once.  For example, John Luciani maintains a fabulous website
containing lots of footprints he generated using Perl:

http://www.luciani.org/geda/pcb/pcb-footprint-list.html

DJ Delorie has several web-based footprint generation programs on
gedasymbols.org:

There are many other automatic footprint generation tools you can find
via a little Googling, including one recently posted on geda-user
written in Ruby.

These tools perform the same job -- parameterized automatic footprint
generation -- as the M4 system, but without the confusion of two
separate footprint mechanisms, where one uses an obscure, undocumented
macro language.
