- # 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 derived from $0)
- # -c file: alternative config.c template (default $srcdir/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.in 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 void init<module>();' before MARKER 1
- # + insert '{"<module>", initmodule},' 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
