LinuxQuestions.org - Perl Module ManPages

I consider myself a true novice of Perl and wanted to know how one may find what functions/commands each perl module contains. I am tired of going to

http://search.cpan.org/~maxschube/Nm...ner/Scanner.pm

and reading through stuff and alot of times they dont go over all the functions that the module may contain. An example "get_host_list,get_next,hostname":

Code:

  use Nmap::Scanner;

  my $scan = Nmap::Scanner->new();

  

  $scan->add_target('localhost');

  $scan->add_target('host.i.administer');

  $scan->add_scan_port('1-1024');

  $scan->add_scan_port('31337');

  $scan->tcp_syn_scan();

  $scan->noping();

  

  my $results = $scan->scan();

  

  my $hosts = $results->gethostlist();

  

  while (my $host = $hosts->get_next()) {

  

      print "On " . $host->hostname() . ": \n";

  

      my $ports = $host->get_port_list();

  

      while (my $port = $ports->get_next()) {

          print join(' ',

              'Port',

              $port->service() . '/' . $port->portid(),

              'is in state',

              $port->state(),

              "\n"

          );

      }

  

  }

its a bit confusing. Any help would be most appriciated.
