00024 //       Class : WindowsRegistry
00025 // Description : This class provides a hook to Python to read and
00026 //               write strings and integers to the windows registry.
00027 //               It automatically converts strings from utf-8 encoding
00028 //               and stores them in Unicode (and conversely reconverts
00029 //               them on retrieval).
