Re: gEDA-user: How's my footprint?

[Steve Meier <smeier@xxxxxxxxxxxxxxxxxxx>]

Ben,

I don't see anything inherently wrong. But it is probably a little
dated. Were you using my doc?

For today's  capabilities I would suggest that instead of working in
units of mills you work in units of 0.01 mills.

I won't or don't have time to check it for correctness otherwise. But
you seem to be on the right tract.
