title: using properties within the properties file
body: <p>I apologize for the title.. i couldn't find a better way to explain the situation.</p>
  
  <p>I use to load properties file using a Property class as described in the URL <a href="http://www.exampledepot.com/egs/java.util/Props.html" rel="noreferrer">http://www.exampledepot.com/egs/java.util/Props.html</a> </p>
  
  <p>my question is can I use properties within that properties file ?</p>
  
  <p>example:</p>
  
  <p>test.properties</p>
  
  <pre><code> url.main="http://mysite.com"
      url.games={url.main}/games
      url.images={url.main}/images
      .
      .
      .
  </code></pre>
  
  <p>is that possible with some other syntax?</p>
  
  <p>thanks</p>
