/**
 * This is an example program to explain how to write an application to send a
 * v3 Inform request message using com.adventnet.snmp.snmp2 package of 
 * AdventNetSNMP2 api.
 * The user could run this application by giving any one of the following usage.
 *  
 * java snmpv3informreq [-d] [-p port] [-u user] 
 * [-a auth_protocol] [-w auth_password] [-s priv_password] [-i context_id] 
 * host TimeTicksvalue OIDvalue [OID {INTEGER | STRING | GAUGE | TIMETICKS | 
 * OPAQUE | IPADDRESS | COUNTER | COUNTER64 | UNSIGNED32} value] ...
 * e.g.
 * java snmpv3informreq -u intial2 -a MD5 -w initial2Pass -i initial 
 * 10.3.2.120 16352 .1.3.6.1.4.1.2162.1000.2 .1.3.6.1.4.1.2162.1001.21.0 STRING 
 * InformReqTest
 *
 * If the oid is not starting with a dot(.) it will be prefixed by .1.3.6.1.2.1.
 * So the entire OID of 1.1.0 will become .1.3.6.1.2.1.1.1.0 . You can also
 * give the entire OID .
 *
 * Options:
 * [-d]                  - Debug output. By default off.
 * [-p] <port>           - remote port no. By default 162.
 * [-u] <username>       - The v3 principal/userName
 * [-a] <autProtocol>    - The authProtocol(MD5/SHA). Mandatory if authPassword is specified
 * [-pp] <privProtocol>  - The privProtocol(DES/AES).
 * [-w] <authPassword>   - The authentication password.
 * [-s] <privPassword>   - The privacy protocol password. Must be accompanied 
 * with auth password and authProtocol fields.
 * [-n] <contextName>    - The contextName to be used for the v3 pdu.
 * [-i] <contextID>      - The contextID to be used for the v3 pdu.
 * <timeticks> Mandatory - the value of object sysUpTime when the event occurred
 * <OID-value> Mandatory - Object Identifier
 * <host>      Mandatory - The RemoteHost.Format (string without double
 * quotes/IpAddress).
 * <OID>       Mandatory - Object Identifier.
 * <value>     Mandatory - The object instance value to be set.
 *
 * Note: Here the Engine Id need not be specified since this application will do
 * a discovery initially.
