# Versions tested on Debian Buster 2020-05-12:
#  KiCad 5.1.5, 5.1.6-rc1
#  KiBoM commit 38525f3  XXX port to 1.7.1
#    (commit 38525f3 is not python3-compatible)

# The export-steps have been scripted as far as reasonably possible with
# Kicad 5.1.x, some files still need to be generated manually ...

# Start the GUI with:
#  kicad AMC_FMC_Carrier-PcbDoc.pro

# click layout
