Incidentally, there is good pcb-rnd support out of the box for freerouting
as a standalone application via specctra export/import, plus integration
from within pcb-rnd
See
https://github.com/freerouting/freerouting
Be aware that mt -1 i.e. multithreading using only one thread is the
safest option with freerouting, as they are yet to iron out some race
conditions it seems.
Regards,
Erich
