# Convert templates into Makefile and config.c, based on the module
# definitions found in the file Setup.
#
# Usage: makesetup [-s dir] [-c file] [-m file] [Setup] ... [-n [Setup] ...]
#
# Options:
# -s directory: alternative source directory (default .)
# -l directory: library source directory (default derived from $0)
# -c file: alternative config.c template (default $libdir/config.c.in)
# -c -: don't write config.c
# -m file: alternative Makefile template (default ./Makefile.pre)
# -m -: don't write Makefile
#
# Remaining arguments are one or more Setup files (default ./Setup).
# Setup files after a -n option are used for their variables, modules
# and libraries but not for their .o files.
#
# See Setup for a description of the format of the Setup file.
#
# The following edits are made:
#
# Copying config.c.in to config.c:
# - insert an identifying comment at the start
# - for each <module> mentioned in Setup before *noconfig*:
# + insert 'extern PyObject* PyInit_<module>(void);' before MARKER 1
# + insert '{"<module>", PyInit_<module>},' before MARKER 2
#
# Copying Makefile.pre to Makefile:
# - insert an identifying comment at the start
# - replace _MODBUILT_NAMES_ by the list of *static* and *shared* modules
# from Setup
# - replace _MODBSHARED_NAMES_ by the list of *shared* modules from Setup
# - replace _MODDISABLED_NAMES_ by the list of *disabled* modules from Setup
# - replace _MODOBJS_ by the list of objects from Setup (except for
# Setup files after a -n option)
# - replace _MODLIBS_ by the list of libraries from Setup
# - for each object file mentioned in Setup, append a rule
# '<file>.o: <file>.c; <build commands>' to the end of the Makefile
# - for each module mentioned in Setup, append a rule
# which creates a shared library version to the end of the Makefile
# - for each variable definition found in Setup, insert the definition
# before the comment 'Definitions added by makesetup'
# Loop over command line options
