title: Purpose and usage of "application.path" variable
body: <p>In the Play! framework source for the <code>main</code> method in <code>Server.java</code> I found these two lines:</p>
  
  <pre><code>File root = new File(System.getProperty("application.path"));
  if (System.getProperty("precompiled", "false").equals("true")) {
      Play.usePrecompiled = true;
  }
  </code></pre>
  
  <p>Where can I find the <code>application.path</code> value?</p>
