This would be useful. The insertion of proper footprint names in
gattrib is currently the slowest part (for me anyway) of going from
gschem to PCB.

We run a robot design project, subdivided into mechanical, electrical

I'll try to remember to modify gsch2pcb. The framework exists in
gnetlist to include rules about the name space of the output format and
deal with it. For example, pa

We're hoping to introduce more students to gEDA here at Cambridge, and
as a related project, myself and Peter Brett spent our summers

Another dumb question. I teach a class of undergraduates about ECAD and
