 Perl access to the telnet interface on Trango Foxes, SUs and APs.  =head1 DESCRIPTION
   
 Another handy feature is that it will parse the output from certain commands that is in the format "[key1] value1 [key2] value2" and put those in a hashref that is returned.  This makes using the output from things like sysinfo very easy to do.  Perl access to the telnet interface on Trango Foxes, SUs and APs.
