title: How to use layout.jade in express 3.0.0rc2
body: <p>I just updated to express 3.0.0rc2 . Everything works fine except the layout.jade isn't used anymore. When I had the old version I just was using this line to set jade as default view engine.</p>
  
  <pre><code>app.set("view engine", "jade");
  </code></pre>
  
  <p>I'm rendering like this right now but it doesn't work.</p>
  
  <pre><code>app.render(view, {opt1: 1,opt2: 2, layout: "layout.jade"}, callback);
  </code></pre>
  
  <p>I didn't needed this before but just in case I tried this out with no success</p>
  
  <pre><code>app.set("view options", {
      layout: true
  });
  </code></pre>
  
  <p>I even tried it like this:</p>
  
  <pre><code>app.engine('jade', require('jade').__express);
  // instead of this: app.set("view engine", "jade");
  </code></pre>
  
  <p>I hope someone knows how to use the layout.jade in the new version. Thanks</p>
