title: Iron Python - No module named "os"
body: <p>I have been trying to debug this sample code, but I am having trouble.</p>
  
  <p><strong>Here is the code:</strong></p>
  
  <pre><code>import System
  import get_events_devices

  clr.AddReference("IronPython") 
  
  class Check: # namespace
  
      class Form1(System.Windows.Forms.Form):

              super(type(self), self).Dispose(disposing)
  
          @returns(None)
          def InitializeComponent(self):

              get_events_devices.units()
  </code></pre>
  
  <p>I have just added optparse.py, get_events_devices.py, and iron python.dll. </p>
  
  <p>From where I get ironpython_module.dll as I have install Iron Python I am not getting this .dll?</p>
  
  <p>Any ideas?</p>
