title: app.yaml apparently not redirecting correctly
body: <p>I've been trying to set up a basic Wordpress site with Google App Engine's new PHP SDK, following <a href="https://developers.google.com/appengine/articles/wordpress" rel="nofollow">these instructions</a>.</p>
  
  <p>From what I understand, <code>app.yaml</code> is where the process kicks off and should work similar to <code>.htaccess</code> (re routing). </p>
  
  <p>Google instruct you to drop your wordpress files into a wordpress folder, so your directory structure looks like this:</p>
  
  <pre><code>.
      ├── app.yaml
      ├── cron.yaml
      ├── php.ini
      └── wordpress
          ├── index.php
          ├── license.txt
          ├── readme.html
          └── (etc)
  </code></pre>
  
  <p>So their template <code>app.yaml</code> should work, including the following lines:</p>
  
  <pre><code>- url: /wp-cron.php
    script: wordpress/wp-cron.php
    login: admin
  
  - url: /xmlrpc.php
    script: wordpress/xmlrpc.php
  
  - url: /(.+)?/?
    script: wordpress/index.php
  </code></pre>
  
  <p>But <strong><code>localhost:8080</code> gives me my app folder's directory structure, instead of the anticipated <code>wordpress/index.php.</code></strong>  I tried this as well:</p>
  
  <pre><code>- url: /.*
    script: wordpress/index.php
  </code></pre>
  
  <p>Any ideas?  </p>
  
  <p>Note: I verified that <code>wordpress/index.php</code> exists, by the way.</p>
