Issue #25224: README.txt is now an idlelib index for IDLE developers and

curious users.  The previous user content is now in the IDLE doc and is
redundant.  IDLE now means 'Integrated Development and Learning Environment'.

-IDLE is the Python IDE built with the :mod:`tkinter` GUI toolkit.
+IDLE is Python's Integrated Development and Learning Environment.
 
 IDLE has the following features:
 

Lib/idlelib/README.txt

-IDLE is Python's Tkinter-based Integrated DeveLopment Environment.
-
-IDLE emphasizes a lightweight, clean design with a simple user interface.
-Although it is suitable for beginners, even advanced users will find that
-IDLE has everything they really need to develop pure Python code.
-
-IDLE features a multi-window text editor with multiple undo, Python colorizing,
-and many other capabilities, e.g. smart indent, call tips, and autocompletion.
-
-The editor has comprehensive search functions, including searching through
-multiple files.  Class browsers and path browsers provide fast access to
-code objects from a top level viewpoint without dealing with code folding.
-
-There is a Python Shell window which features colorizing and command recall.
-
-IDLE executes Python code in a separate process, which is restarted for each
-Run (F5) initiated from an editor window.  The environment can also be 
-restarted from the Shell window without restarting IDLE.
-
-This enhancement has often been requested, and is now finally available.  The
-magic "reload/import *" incantations are no longer required when editing and
-testing a module two or three steps down the import chain.
-
-(Personal firewall software may warn about the connection IDLE makes to its
-subprocess using this computer's internal loopback interface.  This connection
-is not visible on any external interface and no data is sent to or received
-from the Internet.)
-
-It is possible to interrupt tightly looping user code, even on Windows.
-
-Applications which cannot support subprocesses and/or sockets can still run
-IDLE in a single process.
-
-IDLE has an integrated debugger with stepping, persistent breakpoints, and call
-stack visibility.
-
-There is a GUI configuration manager which makes it easy to select fonts,
-colors, keybindings, and startup options.  This facility includes a feature
-which allows the user to specify additional help sources, either locally or on
-the web.
-
-IDLE is coded in 100% pure Python, using the Tkinter GUI toolkit (Tk/Tcl)
-and is cross-platform, working on Unix, Mac, and Windows.
-
-IDLE accepts command line arguments.  Try idle -h to see the options.
-
-
-If you find bugs or have suggestions or patches, let us know about
-them by using the Python issue tracker:
-
-http://bugs.python.org
-
-For further details and links, read the Help files and check the IDLE home
-page at

+README.txt: an index to idlelib files and the IDLE menu.
+
+IDLE is Pythons 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.
+
+
+IDLELIB FILES
+Implemetation files not in IDLE MENU are marked (nim).
+Deprecated files and objects are listed separately as the end.

+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.
