    single: __deepcopy__() (copy protocol)
 
 In order for a class to define its own copy implementation, it can define
-special methods :meth:`__copy__` and :meth:`__deepcopy__`.  The former is called
-to implement the shallow copy operation; no additional arguments are passed.
-The latter is called to implement the deep copy operation; it is passed one
-argument, the ``memo`` dictionary.  If the :meth:`__deepcopy__` implementation needs
-to make a deep copy of a component, it should call the :func:`deepcopy` function
-with the component as first argument and the memo dictionary as second argument.
-The memo dictionary should be treated as an opaque object.
+special methods :meth:`~object.__copy__` and :meth:`~object.__deepcopy__`.
