title: py2app -- importing external modules
body: <p>Can <code>py2app</code> be set up such that the typical contents of a user's <code>sys.path</code> (when running python, not a py2app .app) are appended at the end of the path that py2app sets up?</p>
  
  <p>I am bundling an application with an interactive python prompt -- I would like other users to be able to use modules they have built, but which are not provided in the main .app. If they try to import something that <em>is</em> bundled with <code>py2app</code>, I'd prefer that the <code>py2app</code> version be used.</p>
  
  <p>The <code>--use-pythonpath</code> and <code>--site-packages</code> options to <code>py2app</code> don't seem to add all the directories that regular python does.</p>
