title: Propel 1.6 - Configuration Example?
body: <p>I'm new to using Propel ORM.  I have generated code and am now trying to integrate the runtime with my PHP project.  I am struggling with initializing the main <code>Propel</code> class.  It appears that the usage should be:</p>
  
  <pre><code>require_once('propel/runtime/lib/Propel.php');
  Propel::configure('/path/to/runtime/config.php');
  Propel::initialize();
  </code></pre>
  
  <p>I cannot find any documentation on what the contents on the runtime configuration should be, other than this:</p>
  
  <p><a href="http://www.propelorm.org/wiki/Documentation/1.6/RuntimeConfiguration" rel="nofollow">http://www.propelorm.org/wiki/Documentation/1.6/RuntimeConfiguration</a></p>
  
  <p>However, this document shows an XML file, <strong>not</strong> a PHP file.  Any ideas?</p>
