title: React-router: Uncaught ReferenceError: Router is not defined
body: <p>I'm following <a href="https://github.com/reactjs/react-router/blob/master/docs/guides/README.md" rel="noreferrer">React Router Guide</a> but I'm not even getting to make the simplest example to work. It says <code>Uncaught ReferenceError: Router is not defined</code>.</p>
  
  <p>I'm including these 3 JavaScript files through <code>cdnjs</code>:</p>
  
  <pre><code>&lt;script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.2/react.js"&gt;&lt;/script&gt;
  &lt;script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.2/JSXTransformer.js"&gt;&lt;/script&gt;
  &lt;script src="https://cdnjs.cloudflare.com/ajax/libs/react-router/0.11.6/react-router.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>And the script the triggers the exception is this:</p>
  
  <pre><code>&lt;script type="text/jsx"&gt;
      Router.run(routes, function (Handler, state) {
          React.render(&lt;Handler/&gt;, document.body);
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>Am I missing anything? Is <code>Router</code> defined somewhere else? That's weird because it's not stated in the docs.</p>
