title: Uninstall all perl modules installed by cpan
body: <p>Yesterday I wanted to test some software and in the documentation it said, to install I just needed to type </p>
  
  <pre><code>cpan -i Software
  </code></pre>
  
  <p>I never used cpan, I just know that it is the perl package manager. (Is it..?) However, it turned out that I needed loads of dependencies, and stupid as I am, I just installed all of them. (First, I had to set up cpan which asked me lots of questions) Long story short, I just want to remove all of it again. I googled a bit, and it seems like cpan does not have an uninstall routine, especially for all the packages at once. 
  Can I just remove some directory or will I run into troubles?</p>
