title: cx_freeze: How do I add package files into library.zip?
body: <p>I've noticed that pytz misses zoneinfo folder when I try to roll a zip for Windows. Right now I have a workaround that I use after <code>python setup.py build</code>, namely</p>
  
  <pre><code>7z a -xr!*.py* build\exe.win32-2.7\library.zip C:\Python27\Lib\site-packages\pytz
  </code></pre>
  
  <p>Is there a proper way to achieve that from <code>setup.py</code> or something?</p>
