title: Load parts of App.Config from another file
body: <p>I like to split my <code>app.config</code> into a user specific part and an application specific part. Is it possible to store a part of the <code>app.config</code> in another file?</p>
  
  <p>I already tried this:</p>
  
  <pre><code>&lt;!DOCTYPE cruisecontrol [&lt;!ENTITY email SYSTEM "email.config"&gt;]  &gt;
  </code></pre>
  
  <p>but this does not load.</p>
  
  <p>Is there another possiblity without changing the application itself?</p>
