Read the section on "PS bloat setting". I have a sample .pcb to use
to calibrate it for the smallest traces.

My laserjet is good to about 5 mils, at least for the printing part.
Below that, the fuzzy edges (from the toner, not the printer) seem to
be "big" compared to the traces.
I think one of the tricks is to find 1/2 or 1/4 oz clad boards,
instead of the common 1 oz clad.

Er, pcb? Just export postscript; that's what it's for. Don't even
bother with gerbers.

Not yet. The API has a hook for it, but nothing supports it yet.
Should be easy enough to tweak the .c sources to put the scale where
you need it.

Cut and paste, nothing else.
