+
+  Windows Registry access module for Python.
+
+  * Simple registry access written by Mark Hammond in win32api
+	module circa 1995.
+  * Bill Tutt expanded the support significantly not long after.
+  * Numerous other people have submitted patches since then.
+  * Ripped from win32api module 03-Feb-2000 by Mark Hammond, and
+    basic Unicode support added.
