title: Enabling ProGuard in Eclipse for Android
body: <p>The new documentation on <a href="http://developer.android.com/guide/developing/tools/proguard.html">ProGuard for Android</a> says to add a line to the default.properties file in the project home directory. However, on opening this file, I read at the top: </p>
  
  <pre><code># This file is automatically generated by Android Tools. 
  # Do not modify this file -- YOUR CHANGES WILL BE ERASED! 
  </code></pre>
  
  <p>Am I missing something?</p>
  
  <p>Also, is there a way to enable ProGuard only for a production build from Eclipse (i.e., when exporting the finished product)?</p>
