EXPORTED FUNCTIONS

       This function will tail the given file.

        task "syslog", "server01", sub {

          tail "/var/log/syslog", sub {
           my ($data) = @_;

           my $server = Rex->get_current_connection()->{'server'};

           print "$server>> $data\n";
          };
        };
