=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you.
 my $hp9300 = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 1
                        )
    or die "Can't connect to DestHost.\n";

 my $class = $hp9300->class();

 print "SNMP::Info determined this device to fall under subclass : $class\n";

=head1 DESCRIPTION

Abstraction subclass for HP network devices which Foundry Networks was the
Original Equipment Manufacturer (OEM) such as the HP ProCurve 9300 series.

For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.

 my $hp9300 = new SNMP::Info::Layer3::HP9300(...);
