I am trying to understand this object and reference part of perl. The $p is an object here and &cb is a reference but I cant understand how this all works here. Can someone please explain this??? 
                          use HTML::LinkExtor;
                          $p = HTML::LinkExtor->new(\&cb,
                         "http://www.perl.com";);

                          sub cb {
                              my($tag, %links) = @_;
                              print FIL "$tag @{[%links]}\n";
                          }
                          $p->parse_file("index.html");
