      Typical use:
      >>> sys.exit(main(sys.argv))
  
      @param argv: The arguments to run it with, e.g. sys.argv.
      @param reactor: The reactor to use. Must be compatible with gtk as this
          module uses gtk API"s.
      @return exitcode: The exit code it returned, as per sys.exit.
