  32
  33 Runs given command sequence on all given directories, in sequence.
  34 If there is no command given, --init is assumed.

  37 Commands:
  38     --help
  39         Print this help text
  40     --version
  41         Print the tool versions
  42     --verbose

  55 AUTOPOINT, LIBTOOLIZE to use specific version of these tools, and
  56 AUTORECONF_OPTS to add options to the call to autoreconf.
