=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $netgear = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly on to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";

print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a
Netgear device through SNMP. See inherited classes' documentation for
inherited methods.
