               Added the `standalone_mode` flag to control the standalone mode.
    
            :param args: the arguments that should be used for parsing.  If not
                         provided, ``sys.argv[1:]`` is used.
            :param prog_name: the program name that should be used.  By default
                              the program name is constructed by taking the file
                              name from ``sys.argv[0]``.
            :param complete_var: the environment variable that controls the
                                 bash completion support.  The default is
                                 ``"_<prog_name>_COMPLETE"`` with prog name in
                                 uppercase.
            :param standalone_mode: the default behavior is to invoke the script
                                    in standalone mode.  Click will then
                                    handle exceptions and convert them into
                                    error messages and the function will never
                                    return but shut down the interpreter.  If
                                    this is set to `False` they will be
                                    propagated to the caller and the return
                                    value of this function is the return value
                                    of :meth:`invoke`.
            :param extra: extra keyword arguments are forwarded to the context
                          constructor.  See :class:`Context` for more information.
