# This script generates a Python interface for an Apple Macintosh Manager.
# It uses the "bgen" package to generate C code.
# The function specifications are generated by scanning the mamager's header file,
# using the "scantools" package (customized for this particular manager).

# NOTE: the scrap include file is so bad that the bgen output has to be
# massaged by hand.
