title: How can I use strip_tags in regular Ruby code (non-rails)?
body: <p>I need to turn HTML into plain text. There's a nice function that does that in ActionView's SanitizeHelper, but I have trouble understanding how I can reference it and use it in a simple test.rb file.</p>

  <p>I would like to be able to call <code>strip_tags("&lt;b&gt;lol&lt;/b&gt;") =&gt; "lol"</code></p>
