That file when done correctly, in a virtual environment, should create the Makefile to produce but errors out on some simple understandings that I cannot grasp right now (for whatever reason).
Anyway, if you are a python3 scripter and know your way around Kicad and pcbnew, please join on in. Oh, here are the error(s) from the above file:
make
sed "s/%%gitversion%%/`git log --date=short --pretty=format:'%h@%cd' -n 1`/" < bumps.kicad_pcb > bumps-fab.kicad_pcb

^^^^^^^^^^^^^^^

Okay. All for now. I see the error and I cannot find a workaround for now.
