title: Import Perl module from another directory
body: <p>I have the following file structure:</p>
  
  <pre><code>|_controllers
  | |___FooController.pm
  |_models
  | |___Foo.pm
  |_utils
  | |___BarUtils.pm
  |_foobar.do
  </code></pre>
  
  <p>I want to know how can I import the modules between files, let say that I want to use Foo.pm on FooControllers.pm or use BarUtils.pm on foobar.do . When I have the files on the same directories I just do </p>
  
  <blockquote>
    <p>use Foo;</p>
  </blockquote>
  
  <p>But in this case I cannot figure out how to do it.</p>
