      3 # Convert templates into Makefile and config.c, based on the module
      4 # definitions found in the file Setup.
      5 #
      6 # Usage: makesetup [-s dir] [-c file] [-m file] [Setup] ... [-n [Setup] ...]
      7 #
      8 # Options:
      9 # -s directory: alternative source directory (default .)
     10 # -l directory: library source directory (default derived from $0)
     11 # -c file:      alternative config.c template (default $libdir/config.c.in)
     12 # -c -:         don't write config.c
     13 # -m file:      alternative Makefile template (default ./Makefile.pre)
     14 # -m -:         don't write Makefile
     15 #
     16 # Remaining arguments are one or more Setup files (default ./Setup).
     17 # Setup files after a -n option are used for their variables, modules
     18 # and libraries but not for their .o files.
     19 #
     20 # See Setup.dist for a description of the format of the Setup file.
     21 #
     22 # The following edits are made:
     23 #
     24 # Copying config.c.in to config.c:
     25 # - insert an identifying comment at the start
     26 # - for each <module> mentioned in Setup before *noconfig*:
     27 #   + insert 'extern PyObject* PyInit_<module>(void);' before MARKER 1
     28 #   + insert '{"<module>", PyInit_<module>},' before MARKER 2
     29 #
     30 # Copying Makefile.pre to Makefile:
     31 # - insert an identifying comment at the start
     32 # - replace _MODBUILT_NAMES_ by the list of *static* and *shared* modules
     33 #   from Setup
     34 # - replace _MODDISABLED_NAMES_ by the list of *disabled* modules from Setup
     35 # - replace _MODOBJS_ by the list of objects from Setup (except for
     36 #   Setup files after a -n option)
     37 # - replace _MODLIBS_ by the list of libraries from Setup
     38 # - for each object file mentioned in Setup, append a rule
     39 #   '<file>.o: <file>.c; <build commands>' to the end of the Makefile
     40 # - for each module mentioned in Setup, append a rule
     41 #   which creates a shared library version to the end of the Makefile
     42 # - for each variable definition found in Setup, insert the definition
     43 #   before the comment 'Definitions added by makesetup'
     44 
     45 # Loop over command line options
