This must have broken my whole Ronja project.
The README assumes the polarity is consistent across versions of PCB.
So it's dependent on PCB version now?

Is it possible to make PCB print from commandline or add some PCB
commandline flags to select the polarity or to store the polarity setup
inside the PCB file?

Or make separate program based on existing PCB code that converts .pcb
into Gerbers and postscript?

If someone installs new PCB version, generates the files and sends them
for manufacture (best in 200-piece series as ronjashop.com does), a
mailbomb will arrive to me by mail...
