+ * 14-Mar-2009 Lee C. Baker
+ * - initial implementation
+ *
+ * 15-Mar-2009 Lee C. Baker
+ * - Don't write to (or use) HKEY_CLASSES_ROOT directly
+ * - Externalize strings
+ *
+ * TODO:
+ * - PrintAllAssociations might could be optimized to not fetch all registry subkeys under 'Classes', just the ones that start with '.'
+ * - Make sure that non-administrator users can list associations, and get appropriate error messages when they don't have sufficient
+ *   priveleges to perform an operation
