+
+ # Let SNMP::Info determine the correct subclass for you. 
+ my $extreme = new SNMP::Info(
+                          AutoSpecify => 1,
+                          Debug       => 1,
+                          # These arguments are passed directly on to SNMP::Session
+                          DestHost    => 'myswitch',
+                          Community   => 'public',
+                          Version     => 1

+ print "SNMP::Info determined this device to fall under subclass : $class\n";
+
+=head1 DESCRIPTION
+
+Provides abstraction to the configuration information obtainable from an 
+Extreme device through SNMP. 
+
+For speed or debugging purposes you can call the subclass directly, but not after determining
+a more specific class using the method above.
