# This script combines interface description XML files, with the opcode ini
# to generate two files:
# binding.cpp: Defines a module that binds functions to opcodes.
# functions.cpp: Stubs for every opcode that unpack all the known arguments
#
# Input:
# SCM.ini
# SCM.xml
#
# SCM.ini is used to document the stub with expected behaviour
# SCM.xml is used to determine the correct types for each argument
