+err.py  Encapsulated writing to sys.stderr
+
+The idea of this module is that, for a GUI system (or a more advanced UI),
+you can just import a different err module (or object) and keep 
+your code the same.  (For instance, you often want a status window
+which flashes warnings and info, and have error messages pop up an 
+alert to get immediate attention.
