Look at the list of gnetlist back ends. My customers usually have  
their favored layout designers or contractors, with their favored  
tools, so I export whatever they want. For my VLSI work, that's a  
stripped-down hierarchical SPICE netlist that I generate with the  
spice-sdb back end (thanks, Stuart) and a Makefile that cat's the  
pieces together.

In other cases I've had to write my own back ends. I thoroughly  
appreciate how easy this is. The Osmond and Calay back ends I wrote  
are part of the regular distribution. Osmand was particularly easy  
because they fully document their netlist format: no guesswork required.

I also have a gnetlist back end for Lincoln Laboratory's old PH70 PCB  
layout tool, but as I believe the last user of that has retired, I  
don't suppose it's worth distributing ;-)

I've been using gEDA since 2002, but I've never used pcb. That may  
change in the near future: there are a couple of potential projects  
coming up where I expect to do my own layout. Nice to know it's there.
