# 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.dist 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 _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
