From 0dc05b5e1f96a0031221729d1ef5776889fc3e66 Mon Sep 17 00:00:00 2001
From: Miles Bader <miles@gnu.org>

Subject: (main):   Exit with a non-zero status if we fixed anything.   Use
 argp to parse options. (options): Converted to argp format. (args_doc): New
 variable. (USAGE, usage, SHORT_OPTIONS): Removed. Include <argp.h> instead of
 <getopt.h>.
