-PyShellWindow is a class that provides an Interactive Interpreter running
-inside a wxStyledTextCtrl, similar to the Python shell windows found in
-IDLE and PythonWin.
-
-There is still much to be done to improve this class, such as line
-buffering/recall, autoindent, calltips, autocomplete, fixing the colourizer,
-etc... But it's a good start.

-
-8-10-2001 THIS MODULE IS NOW DEPRECATED. Please see the most excellent
- PyCrust package instead.
