    Registers an unpack format. *name* is the name of the format and
    *extensions* is a list of extensions corresponding to the format, like
    ``.zip`` for Zip files.
 
    *function* is the callable that will be used to unpack archives. The
-   callable will receive the path of the archive, followed by the directory
-   the archive must be extracted to.
-
-   When provided, *extra_args* is a sequence of ``(name, value)`` tuples that
-   will be passed as keywords arguments to the callable.

+   - additional keyword arguments, specified by *extra_args* as a sequence

    *description* can be provided to describe the format, and will be returned
    by the :func:`get_unpack_formats` function.
