    *default(obj)* is a function that should return a serializable version of
    *obj* or raise :exc:`TypeError`.  The default simply raises :exc:`TypeError`.
 
+   If *sort_keys* is ``True`` (default: ``False``), then the output of
+   dictionaries will be sorted by key.

    To use a custom :class:`JSONEncoder` subclass (e.g. one that overrides the
    :meth:`default` method to serialize additional types), specify it with the
    *cls* kwarg; otherwise :class:`JSONEncoder` is used.

    Serialize *obj* to a JSON formatted :class:`str`.  The arguments have the
    same meaning as in :func:`dump`.
