title: How do I launch the default web browser in Perl on any operating system?
body: <p>I want to open a URL, such as <code>http://www.example.com/</code>, at the end of a Perl script. I don't want to access it with WWW::Mechanize but actually show the web page to the user in a graphical web browser.</p>
  
  <p>There are ways to do this in Mac (<code>open URL</code>) and Windows, but I want a solution that works on any operating system, not just one.</p>
