/**
 * This is an example program to explain how to write an application to do
 * the basic SNMP operation GETBULK using com.adventnet.snmp.snmp2 and
 * com.adventnet.snmp.mibs packages of AdventNetSNMP2 api.
 * The user could run this application by giving any one of the following usage.
 *  
 * Note: The values of non-repeaters max-repetitions should be the last arguments
 * 
 * java snmpbulk [options] hostname oid [oid] ... non-repeaters max-repetitions
 *
 * v2c request:
 * java snmpbulk [-d] [-m MIB_files] [-c community] [-p port] [-t timeout] [-r retries] host OID [OID] ... nonRepeaters maxRepetions
 * e.g. 
 * java snmpbulk -p 161 -c public -m ../../../mibs/RFC1213-MIB adventnet 1.2.0 1.2.0 1.5.0 1 2
 *
 * v3 request:
 * java snmpbulk [-d] [-v version(v2,v3)] [-c community] [-m MIB_files] [-p port] [-r retries] [-t timeout] [-u user] [-a auth_protocol] [-w auth_password] [-s priv_password] [-n contextName] [-i contextID] host OID [OID] ... nonRepeaters maxRepetions
 * e.g.
 * java snmpbulk -v v3 -c public -m ../../../mibs/RFC1213-MIB -p 161 -u advent -a MD5 -w authPass localhost 1.2.0 1.3.0 1.4.0 1 2
 * 
 * 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 .
 * 
 * Options:
 * [-d]                - Debug output. By default off.
 * [-c] <community>    - community String. By default "public".
 * [-p] <port>         - remote port no. By default 161.
 * [-t] <Timeout>      - Timeout. By default 5000ms.
 * [-r] <Retries>      - Retries. By default 0. 
 * [-m] <MIBfile>      - MIB files.To load multiple mibs give within double quotes files seperated by a blank space.       
 * [-v] <version>      - version(v2 / v3).
 * [-u] <username>     - The v3 principal/userName
 * [-a] <authProtocol> - 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 contextName to be used for the v3 pdu.
 * [-i] <contextID>    - The contextID to be used for the v3 pdu.
 * <host> Mandatory    - The RemoteHost (agent).Format (string without double qoutes/IpAddress).
 * <OID>  Mandatory    - Give only one Object Identifier.
 * <nonRepeaters>      - non-repeaters. Mandatory
 * <maxRepetions>      - max-repetitions. Mandatory
