+# 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
