Simple information on how to comment multiple lines in a perl script. We use # [Hash] to comment a single line in perl. But when it comes to multiple line putting # [Hash] in each line will be a hilarious task if the script is big. Here we can use head and cut to comment multiple lines.
Just add =head in the beginning of the script where you need to start commenting and =cut at the end of the line you need to stop commenting.
=head while (<xml_handler>) { print "$_"; } print xml_handler "Testing"; close xml_handler or die "The walking dead will not cease and desist: $!"; =cut
