+* The :func:`shutil.copytree` function now has an optional **ignore** argument
+  that takes a callable object.  This callable will receive each directory path
+  and a list of the directory's contents, and returns a list of names that
+  will be ignored, not copied.

+  The :mod:`shutil` module also provides an :func:`ignore_patterns`
+  function for use with this new parameter.
+  :func:`ignore_patterns` takes an arbitrary number of glob-style patterns
