13: =head1 SYNOPSIS
14:
15: use Net::Telnet::Trango;
1.3 andrew 16: my $t = new Net::Telnet::Trango ( Timeout => 5 );
1.2 andrew 17:
1.6 andrew 18: $t->open( Host => $fox ) or die "Error connecting: $!";
1.2 andrew 19:
20: $t->login('password') or die "Couldn't log in: $!";

26:
27: =head1 DESCRIPTION
28:
29: Perl access to the telnet interface on Trango Foxes, SUs and APs.
30:
31: 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.

50: Same as new from L<Net::Telnet> but has defaults for the trango 'Prompt'
51:
1.9 andrew 52: It also takes an optional parameter 'Decode'. If not defined it
53: defaults to 1, if it is set to 0, it will not decode the output and
54: instead return an array of the lines that were returned from the
55: command.

940: =head1 TODO
941:
942: There are still a lot of commands that are not accessed directly. If you call them (as cmd("command + args") or whatever) and it works, please send me examples that work and I will try to get it incorporated into the next version of the script.
943:
944: I also want to be able to parse the different types of output from commands like su, sudb all and anything else that would be better available as a perl datastructure.
