title: JavaScript minifier that strips out unused code
body: <p>Does anyone know of a JavaScript minifer that can detect unused code and strip it out.</p>
  
  <p>Google Closure seems alright but it appears to only compact.</p>
  
  <p>I'm looking for something much more advanced, where it can look through my JavaScript and not only compact but also remove unused code.</p>
  
  <p>Anyone know of such a tool?</p>
  
  <p>The use base being, I use very little functionality of JQuery - what I would like to do is remove from the base/core all the bloat that is unneeded from my use.</p>
