# makekey.py - A key making tool
# This program will accept a pin configuration for a Lockwood 6 Pin lock and produce GCode to mill out the corresponding key.
#
# For example, this will produce a bump key:
# $ ./makekey.py 999999
#
# This could produce a key to something else:
# $ ./makekey.py 123456
#
# My dearest apologies if that happens to be yours.
#
# This is also a real key, as there does not exist a 'missing' pin:
# $ ./makekey.py 000000
