/** 
 *  Send SNMP inform based on command line arguments.  Loads MIBs 
 *  as specified, and converts to/from names for loaded MIB data. 
 *  Since variable types are not input, MIBs have to be loaded for
 *  any variables being used in inform PDU.
 *
 * This is an example program to explain how to write an application to send a
 * inform message using com.adventnet.snmp.beans package of AdventNetSNMP api.
 * The user could run this application by giving any one of the following usage.
 *  
 * Note: Refer README file  
 *
 * 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 .
 * 
 * If the mib is loaded you can also give string oids in the following formats
 * .iso.org.dod.internet.mgmt.mib-2.system.sysDescr.0 or system.sysDescr.0 or
 * sysDescr.0 .
 *
 * [-d]                - Debug output. By default off.
 * [-c] <community>    - community String. By default "public".
 * [-p] <port>         - remote port no. By default 161.
 * [-m] <mibs>         - The mibs to be loaded. 
 * [-v] <version>      - version(v2 / v3). By default v2.
 * [-u] <username>     - The v3 principal/userName
 * [-a] <autProtocol>  - The authProtocol(MD5/SHA). Mandatory if authPassword is specified
 * [-w] <authPassword> - The authentication password.
 * [-s] <privPassword> - The privacy protocol password. Must be accompanied with auth password and authProtocol fields.
 * [-n] <contextName>  - The snmpv3 contextName to be used.
 * [-i] <contextID>    - The snmpv3 contextID to be used.
 * [-pp] <privProtocol> - The privacy protocol. Must be accompanied with auth,priv password and authProtocol fields.
 * <host> Mandatory    - The RemoteHost (agent).Format (string without double qoutes/IpAddress).
 * <timeticks> Mandatory - the value of object sysUpTime when the event occurred
 * <OID-value> Mandatory - Object Identifier  
 * <OID>  Mandatory    - Give multiple no. of Object Identifiers.
