title: Multiple Static Directories in Python Tornado
body: <p>I have a directory structure setup like:</p>
  
  <pre><code>root/
    js/
    css/
    libs/
    index.html
  </code></pre>
  
  <p>From Tornado, I want to serve js, css, and libs as static directories, but I can only find out how to serve one of them. Can this be done?</p>
