title: Python package build works, but the zip in dist does not have all files
body: <p>The build of my daysgrounded package works fine with the command</p>
  
  <pre><code>python setup.py sdist bdist_wininst bdist_egg bdist_wheel
  </code></pre>
  
  <p>in my dist dir appear these files:</p>
  
  <pre><code>daysgrounded-0.0.10.win32.exe
  daysgrounded-0.0.10.zip
  daysgrounded-0.0.10-py2.7.egg
  daysgrounded-0.0.10-py2.py3-none-any.whl
  </code></pre>
  
  <p>The egg and whl have all the text files inside the daysgrounded dir, but the zip does not. It only contains the source code py files.
  This is the setup.py</p>
