  $USAGE = qq/This program is used to perform various translations of numeric and symbolic
OIDS using the UCD-SNMP \/ NET-SNMP Perl module and the translateObj function.

The test results should assist with determining if the installed Perl module 
will function as expected with SNMPTT.

For UCD-SNMP, and Net-SNMP 5.0.8 and previous versions, use --best_guess=0.

For Net-SNMP 5.1, or any Net-SNMP with patch 722075 applied, use 
--best_guess=2.

Usage:

  net-snmp-test          [<options>]
Options:

  --help                 Display this message
  --version              Display author and version information
  --best_guess=n         Display author and version information
