README.txt: an index to idlelib files and the IDLE menu.

IDLE is Python's Integrated Development and Learning
Environment.  The user documentation is part of the Library Reference and
is available in IDLE by selecting Help => IDLE Help.  This README documents
idlelib for IDLE developers and curious users.

IDLELIB FILES lists files alphabetically by category,
with a short description of each.

IDLE MENU show the menu tree, annotated with the module
or module object that implements the corresponding function.

This file is descriptive, not prescriptive, and may have errors
and omissions and lag behind changes in idlelib.

IDLE MENUS
Top level items and most submenu items are defined in Bindings.
Extenstions add submenu items when active.  The names given are
found, quoted, in one of these modules, paired with a '<<pseudoevent>>'.
Each pseudoevent is bound to an event handler.  Some event handlers
call another function that does the actual work.  The annotations below
are intended to at least give the module where the actual work is done.
