Again, if you can come up with a working circuit that (1) uses all the
different footprints, (2) costs less than $2, and (3) fits in about
half a square inch, I'm all for it.

Almost missed this comment.
The intent is to see how small a part you can hand solder. There was
a thread about that a while back.

Cool, that $5 more I can spend on PCB fab if needed. Actually, the

pcb doesn't use gafrc. Use "pcb --help" and look for the two options
