Automated Browsing in Perl

I'm reminded on today's Perl course just how powerful some of the modules are, and how much you can do in so little code.

LWP::UserAgent turns your Perl into an automated browser .. the following four lines reading the robots.txt off my web site.

use LWP::UserAgent;
$connex = new LWP::UserAgent("agent" => "007");
$response = $connex->get("http://www.wellho.net/robots.txt");
print $response->decoded_content;
