#
# Modulator - Generate skeleton modules.
#
# The user fills out some forms with information about what the module
# should support (methods, objects), names of these things, prefixes to
# use for C code, whether the objects should also support access as numbers,
# etc etc etc.
# When the user presses 'Generate code' we generate a complete skeleton
# module in C.
#
# Alternatively, the selections made can be save to a python sourcefile and
# this sourcefile can be passed on the command line (resulting in the same
# skeleton C code).
#
# Jack Jansen, CWI, October 1994.
