Pinnumbers are "numbers" in the first place. Former versions of netlisters/PCB
got confused by non-digital pinnumbers.
With this approach you have to have a SOT23 footprint with 1,2,3 pinout,
A,K,NC pinout, A1,A2,K pinout, B,

I don't think it's a good idea. Instead, I use my own library, where pin
numbers are consistent. In addition I have my perl scripts which can add pin
number

This is why I habitually move the m4 lib out of the way, so gnetlist

Welcome back to the transistor problem :-P

Probably. I've b
I was double checking a pcb layout today and I discovered a rather nasty
gotcha. It seems that gschem and PCB don't agree on which end of a diode
should be pin 1. Gschem views pin 1 as the anode and PCB considers pin 1
to be the cathode. It doesn't prevent you from laying out a board
correctly,
