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 void init<module>(void);' before MARKER 1
28# + insert '{"<module>", initmodule},' before MARKER 2
29#
30# Copying Makefile.pre to Makefile:
31# - insert an identifying comment at the start
32# - replace _MODOBJS_ by the list of objects from Setup (except for
33# Setup files after a -n option)
34# - replace _MODLIBS_ by the list of libraries from Setup
35# - for each object file mentioned in Setup, append a rule
36# '<file>.o: <file>.c; <build commands>' to the end of the Makefile
37# - for each module mentioned in Setup, append a rule
38# which creates a shared library version to the end of the Makefile
39# - for each variable definition found in Setup, insert the definition
40# before the comment 'Definitions added by makesetup'
