title: upgrade foundation 3 to 4
body: <p>i have recently just upgraded from foundation 3 to 4, though I have noticed that I cannot get zepto to work correctly. I keep getting the following</p>
  
  <pre><code>Started GET "/js/vendor/zepto.js" for 127.0.0.1 at 2013-03-12 00:03:30 +1100
  
  ActionController::RoutingError (No route matches [GET] "/js/vendor/zepto.js"):
  </code></pre>
  
  <p>i have followed the instructions to a tee, and googled to try and find a solution without any luck</p>
  
  <p>this is in my footer</p>
  
  <pre><code>= javascript_include_tag :application
  :javascript
    document.write('&lt;script src=/js/vendor/'
      + ('__proto__' in {} ? 'zepto' : 'jquery')
      + '.js&gt;&lt;\/script&gt;');
  / Check for Zepto support, load jQuery if necessary
