I just realized that this *is* the script from Pharo. I think you need  
to carefully check what is applicable for Squeak since I was quite  
aggressive with respect to deleting objects -- especially bitmaps that  
we don't need in Pharo anymore but that you may still need in Squeak  
(e.g., for EToys).
