=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you.
 my $genua = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myhub',
                          Community   => 'public',
                          Version     => 2
                        )
    or die "Can't connect to DestHost.\n";

 my $class = $genua->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";
