+ * @brief Guard implementation used to make object group cleanup
+ *        exception-safe.
+ *
+ * This guard's destructor performs cleanup of object group
+ * resources.  Thus, cleanup is performed when this guard goes out of
+ * scope unless explicitly released from that responsibility.
+ *
+ * This guard is meant to be used internally by the
+ * TAO_PG_GenericFactory class.
