title: Jade - conditional to write out javascript
body: <p>Im struggling to translate my HTML/JavaScript to Jade. Here is the source:</p>
  
  <pre><code>&lt;!--[if !IE]&gt; --&gt;
  &lt;script type="text/javascript"&gt;
      window.jQuery || document.write("&lt;script src='../assets/js/jquery.min.js'&gt;"+"&lt;"+"/script&gt;");
  &lt;/script&gt;
  &lt;!-- &lt;![endif]--&gt;
  </code></pre>
  
  <p>Can anyone advise how I would define this using Jade?</p>
