title: Standard way to open a folder window in linux?
body: <p>I want to open a folder window, in the appropriate file manager, from within a cross-platform (windows/mac/linux) Python application.</p>
  
  <p>On OSX, I can open a window in the finder with</p>
  
  <pre><code>os.system('open "%s"' % foldername)
  </code></pre>
  
  <p>and on Windows with</p>
  
  <pre><code>os.startfile(foldername)
  </code></pre>
  
  <p>What about unix/linux? Is there a standard way to do this or do I have to special case gnome/kde/etc and manually run the appropriate application (nautilus/konqueror/etc)?</p>
  
  <p>This looks like something that could be specified by the <a href="http://freedesktop.org" rel="noreferrer">freedesktop.org</a> folks (a python module, similar to <code>webbrowser</code>, would also be nice!).</p>
