+// = DESCRIPTION
+// This class is fully contained and does not rely on or any other
+// SNMP libraries. This class is portable across any platform
+// which supports C++. Ported to ACE by Mike MacFaden mrm@cisco.com 
+// and modified for MT. Some API cleanup: collapse constructors,
+// add suboid() method remove unnecessary overload, and update a few 
+// names and types to improve clarity.
