:Sample Code:
    .. code-block:: python

        from argparse import ArgumentParser

        from pathvalidate.argparse import sanitize_filename_arg, sanitize_filepath_arg


        parser = ArgumentParser()
        parser.add_argument("--filename", type=sanitize_filename_arg)
        parser.add_argument("--filepath", type=sanitize_filepath_arg)
        options = parser.parse_args()

        if options.filename:
            print("filename: {}".format(options.filename))

        if options.filepath:
            print("filepath: {}".format(options.filepath))

:Output:
    .. code-block:: none

        $ ./examples/argparse_sanitize.py --filename e/g
        filename: eg

.. note::
    ``sanitize_filepath_arg`` is set platform as ``"auto"``.
