        To enable autocomplete in your shell please execute activate-global-python-argcomplete in your shell.

        The arg parser should support two output modes, one for the command line (default) and one for generating
        the documentation. If the flag doc_parser is true the parser should be generated for the documentation.

            doc_parser (boolean): If true the parser should be prepared for the documentation. If false (the default)
                the parser should be generated for the command line.
