/**
 *  Use CORBA to receive traps from a remote server that forwards traps
 *  in CORBA calls.  The server can be serving multiple clients with
 *  traps as they come in.
 *
 *  The CORBA server is specified with the -SnmpServer option
 *  and defaults to localhost if not specified.
 *
 *  Receive traps and print incoming traps.  Loads MIBs 
 *  as specified, and converts to/from names for loaded MIB data. 
 *  It also prints loaded trap names and descriptions when the
 *  corresponding traps are received.
 *  Once a MIB is loaded on the server, susequent uses of
 *  This program will have the MIB available for SNMP operations.
