+- Two new scripts (db2pickle.py and pickle2db.py) were added to the
+  Tools/scripts directory to facilitate conversion from the old bsddb module
+  to the new one.  While the user-visible API of the new module is
+  compatible with the old one, it's likely that the version of the
+  underlying database library has changed.  To convert from the old library,
+  run the db2pickle.py script using the old version of Python to convert it
+  to a pickle file.  After upgrading Python, run the pickle2db.py script
+  using the new version of Python to reconstitute your database.  For
+  example:
+
+    % python2.2 -h some.db > some.pickle
+    % python2.3 -h some.db.new < some.pickle
+
+  Run the scripts without any args to get a usage message.
