    --options, <positional-argument>, commands, which could be
    [optional], (required), (mutually | exclusive) or repeated...
    Parameters
    ----------
    doc : str
        Description of your command-line interface.
    argv : list of str, optional
        Argument vector to be parsed. sys.argv[1:] is used if not
        provided.
    help : bool (default: True)
        Set to False to disable automatic help on -h or --help
        options.
    version : any object
        If passed, the object will be printed if --version is in
        `argv`.
    options_first : bool (default: False)
        Set to True to require options precede positional arguments,
        i.e. to forbid options and positional arguments intermix.
    Returns
    -------
    args : dict
        A dictionary, where keys are names of command-line elements
        such as e.g. "--verbose" and "<path>", and values are the
        parsed values of those elements.
    Example
    -------
    >>> from docopt import docopt
    >>> doc = '''

    ...     my_program tcp <host> <port> [--timeout=<seconds>]
