        """Convenience method to run multiple commands by onecmd_plus_hooks.

        This method adds the given cmds to the command queue and processes the
        queue until completion or an error causes it to abort. Scripts that are
        loaded will have their commands added to the queue. Scripts may even
        load other scripts recursively. This means, however, that you should not
        use this method if there is a running cmdloop or some other event-loop.
        This method is only intended to be used in "one-off" scenarios.

        NOTE: You may need this method even if you only have one command. If
        that command is a load, then you will need this command to fully process
        all the subsequent commands that are loaded from the script file. This
        is an improvement over onecmd_plus_hooks, which expects to be used
        inside of a command loop which does the processing of loaded commands.

        Example: cmd_obj.runcmds_plus_hooks(['load myscript.txt'])

        :param cmds: command strings suitable for onecmd_plus_hooks.
        :return: True implies the entire application should exit.
