def transparent_encode_multipart(func):
    """Wrap an HTTP client method, transparently encoding multipart data.

    This wraps some of Django's `Client` HTTP verb methods -- delete, options,
    patch, put -- so they accept a dict of data to be sent as part of the
    request body, in MIME multipart encoding.

    This also accepts an optional dict of query parameters (as `query`) to be
    encoded as a query string and appended to the given path.

    Since Django 1.5, these HTTP verb methods require data in the form of a
    byte string. The application (that's us) needs to take care of MIME
    encoding.
