title: Verify GPG file signature with Perl
body: <p>I want to verify a GPG signed file (Verify archive.tar.gz with archive.tar.gz.sign). </p>
  
  <p>ATM I simply call gpg directly and parse the exit code and output. While this is a works-for-me solution, I figure there must be a nicer way to do this in a more perlish way.</p>
  
  <p>But as a programming novice I fail to understand how I can use the GPG CPAN modules.</p>
  
  <p>Any hints are much appreciated!</p>
