he ``path`` given as a URL parameter will be rendered.

    If ``path`` is a directory, information about the entries in that
    directory will be rendered. This form is equivalent to the ``manifest``
    handler.

    If ``path`` is a file, information about that file will be shown via
    the ``filerevision`` template.

    If ``path`` is not defined, information about the root directory will
    be rendered.
