/**

 * The get_bulk application shows how to use the SNMPv2 GetBulk request.

 *
 * <p>
 * The host, port, community, non-repeaters and max-repetitions name can 
 * be configured 
 * in the properties file. 
 * A number of OIDs can be configured in the properties file as well by using
 * any OIDS in the range OID0 to OID9.
 * </p>
 * <p>
 * The name of the properties file can be passed as first argument to
 * this application. If there is no such argument, it will look for
 * <code>get_bulk.properties</code>. If this file does not exist, the
 * application will use default parameters.
