I was bored and wanted to see what the source of the typical /bin/false
was.

coreutils-5.0/src/false.c:

<snip>

int
main (int argc, char **argv)
{
  program_name = argv[0];
  setlocale (LC_ALL, "");
  bindtextdomain (PACKAGE, LOCALEDIR);
  textdomain (PACKAGE);

  atexit (close_stdout);

  /* Recognize --help or --version only if it's the only command-line
     argument and if POSIXLY_CORRECT is not set.  */
  if (argc == 2 && getenv ("POSIXLY_CORRECT") == NULL)
    {
      if (STREQ (argv[1], "--help"))
        usage (EXIT_FAILURE);

      if (STREQ (argv[1], "--version"))
        version_etc (stdout, PROGRAM_NAME, GNU_PACKAGE, VERSION,
AUTHORS);
    }

  exit (EXIT_FAILURE);
}

Ain't exactly rocket science modifying that :)
