    """
    Deserialize ``fp`` (a ``.read()``-supporting file-like object containing
    a JSON document) to a Python object.

    If the contents of ``fp`` is encoded with an ASCII based encoding other
    than utf-8 (e.g. latin-1), then an appropriate ``encoding`` name must
    be specified.  Encodings that are not ASCII based (such as UCS-2) are
    not allowed, and should be wrapped with
    ``codecs.getreader(fp)(encoding)``, or simply decoded to a ``unicode``
    object and passed to ``loads()``

    ``object_hook`` is an optional function that will be called with the
    result of any object literal decode (a ``dict``).  The return value of
    ``object_hook`` will be used instead of the ``dict``.  This feature
    can be used to implement custom decoders (e.g. JSON-RPC class hinting).
    
    To use a custom ``JSONDecoder`` subclass, specify it with the ``cls``
    kwarg.
