[MINC-development] "Amusing" mincblur issue...

Mind you further to this, I would be amenable to start to instigate
this change if you didnt have to manually enumerate the usage (--help)
option in getopt_long meaning you are more prone to error and/or not
keeping things up to data ala Perl POD. Add to that that you also have
to manually set variables from what I can see meaning even more code
for each MINC tool.

ie: (from uname.c).

....

static struct option const long_options[] =
{
  {"all", no_argument, NULL, 'a'},
  {"kernel-name", no_argument, NULL, 's'},
  {"sysname", no_argument, NULL, 's'},	/* Obsolescent.  */
  {"nodename", no_argument, NULL, 'n'},
  {"kernel-release", no_argument, NULL, 'r'},
  {"release", no_argument, NULL, 'r'},  /* Obsolescent.  */
  {"kernel-version", no_argument, NULL, 'v'},
  {"machine", no_argument, NULL, 'm'},
  {"processor", no_argument, NULL, 'p'},
  {"hardware-platform", no_argument, NULL, 'i'},
  {"operating-system", no_argument, NULL, 'o'},
  {GETOPT_HELP_OPTION_DECL},
  {GETOPT_VERSION_OPTION_DECL},
  {NULL, 0, NULL, 0}
};

...

void
usage (int status)
{
  if (status != 0)
    fprintf (stderr, _("Try `%s --help' for more information.\n"),
	     program_name);
  else
    {
      printf (_("Usage: %s [OPTION]...\n"), program_name);
      fputs (_("\

\n\
  -a, --all                print all information, in the following order:\n\
  -s, --kernel-name        print the kernel name\n\
  -n, --nodename           print the network node hostname\n\
  -r, --kernel-release     print the kernel release\n\
"), stdout);
      fputs (_("\
  -v, --kernel-version     print the kernel version\n\
  -m, --machine            print the machine hardware name\n\
  -p, --processor          print the processor type\n\
  -i, --hardware-platform  print the hardware platform\n\
  -o, --operating-system   print the operating system\n\
"), stdout);
      fputs (HELP_OPTION_DESCRIPTION, stdout);
      fputs (VERSION_OPTION_DESCRIPTION, stdout);
      printf (_("\nReport bugs to <%s>.\n"), PACKAGE_BUGREPORT);
    }
  exit (status);
}
