Guido van Rossum 504b0bf066 Checking in IDLE 0.2.
Much has changed -- too much, in fact, to write down.
The big news is that there's a standard way to write IDLE extensions;
see extend.txt.  Some sample extensions have been provided, and
some existing code has been converted to extensions.  Probably the
biggest new user feature is a new search dialog with more options,
search and replace, and even search in files (grep).

This is exactly as downloaded from my laptop after returning
from the holidays -- it hasn't even been tested on Unix yet.

# This file defines the menu contents and key bindings. Note that
# there is additional configuration information in the EditorWindow
# class (and subclasses): the menus are created there based on the
# menu_specs (class) variable, and menus not created are silently
# skipped by the code here. This makes it possible to define the
# Debug menu here, which is only present in the PythonShell window.
