title: How to prevent setuptools install package as an .egg
body: <p>For example, installing IPython on Linux (where setuptools is not installed) I've got IPython installed in <code>site-packages\IPython</code>.</p>
  
  <p>Installing IPython on Windows (where IPython requires setuptools), after executing the same command</p>
  
  <pre><code>python setup.py install
  </code></pre>
  
  <p>I get IPython installed in <code>site-packages\ipython-0.13.2-py2.7.egg\IPython</code></p>
  
  <p>Is there a way to install the module "old way" i.e. into <code>site-packages\IPython</code>?</p>
