HELP
  help [all | recipes | TOPIC | CMD]
      'pxart help recipes': seven workflows, command by command; 'help worlds': Tiled worlds.
      'pxart help all' prints this whole reference; 'pxart help TOPIC' one part of
      it (a heading here, any case); 'pxart help CMD' is 'pxart CMD -h'.
      'pxart help compose-rules' and 'pxart help palette-rules' print only the rules those
      sections open with.
