Added module stub for copy_reg renaming in 3.0.
Renamed copy_reg to copyreg in the standard library, to avoid
spurious warnings and ease later merging to py3k branch. Public
documentation remains intact.
........
Classes can use the same interfaces to control copying that they use to control
pickling. See the description of module :mod:`pickle` for information on these
-methods. The :mod:`copy` module does not use the :mod:`copy_reg` registration
+methods. The :mod:`copy` module does not use the :mod:`copyreg` registration
module.

future as well. It provides configuration information about object constructors
which are not classes. Such constructors may be factory functions or class

An alternative to implementing a :meth:`__reduce__` method on the object to be
-pickled, is to register the callable with the :mod:`copy_reg` module. This
+pickled, is to register the callable with the :mod:`copyreg` module. This
module provides a way for programs to register "reduction functions" and
constructors for user-defined types. Reduction functions have the same
semantics and interface as the :meth:`__reduce__` method described above, except
