-   several keyword parameters.
-
-   *stream* (default :data:`!sys.stdout`) is a :term:`file-like object` to
-   which the output will be written by calling its :meth:`!write` method.
-   If both *stream* and :data:`!sys.stdout` are ``None``, then
-   :meth:`~PrettyPrinter.pprint` silently returns.
+   Construct a :class:`PrettyPrinter` instance.
 
-   Other values configure the manner in which nesting of complex data
-   structures is displayed.
+   Arguments have the same meaning as for :func:`~pprint.pp`.
+   Note that they are in a different order, and that *sort_dicts* defaults to ``True``.
 
-   *indent* (default 1) specifies the amount of indentation added for
-   each nesting level.
-
-   *depth* controls the number of nesting levels which may be printed; if
-   the data structure being printed is too deep, the next contained level
-   is replaced by ``...``.  By default, there is no constraint on the
-   depth of the objects being formatted.
-
-   *width* (default 80) specifies the desired maximum number of characters per
-   line in the output. If a structure cannot be formatted within the width
-   constraint, a best effort will be made.
-
-   *compact* impacts the way that long sequences (lists, tuples, sets, etc)
-   are formatted. If *compact* is false (the default) then each item of a
-   sequence will be formatted on a separate line.  If *compact* is true, as
-   many items as will fit within the *width* will be formatted on each output
-   line.
-
-   If *sort_dicts* is true (the default), dictionaries will be formatted with
-   their keys sorted, otherwise they will display in insertion order.
