"getdefs" is for extracting special markup comments into autogen definitions.
Your "options.def" file is already in autogen definitions format.
So, no, that won't work.
WRT creating a shell script to parse options, perhaps it isn't clear enough.
You must go through several steps:
1. generate C source
2. compile a program that emits the shell script
3. run that program
4. incorporate the resulting output into your script.
That would be:
$ autogen joiner-opts.def
# NOTE: do not use options.def as "options.h" conflicts
# note to self: fix this
$ cc -o gen-joiner-opts -DTEST_JOINER_OPTS joiner-opts.c $(
autoopts-config cflags ldflags)
$ ./gen-joiner-opts -o joiner-opts.sh
$ cat joiner-opts.sh
#! /bin/bash
# # # # # # # # # # -- do not modify this marker --
#
# DO NOT EDIT THIS SECTION OF joiner-opts.sh
#
# From here to the next `-- do not modify this marker --',
# the text has been generated Thursday August 9, 2012 at 07:34:59 AM PDT
# From the JOINER option definitions
