Issue #27156: Remove obsolete code not used by IDLE.

help.txt, replaced by help.html, is out-of-date and should not be used.
Its dedicated viewer has be replaced by the html viewer in help.py.
'import idlever; I = idlever.IDLE_VERSION' is the same as
'import sys; I = version[:version.index(' ')]'

-[See the end of this file for ** TIPS ** on using IDLE !!]
-
-IDLE is the Python IDE built with the tkinter GUI toolkit.
-
-IDLE has the following features:
--coded in 100% pure Python, using the tkinter GUI toolkit
--cross-platform: works on Windows, Unix, and OS X
--multi-window text editor with multiple undo, Python colorizing, smart indent,
-call tips, and many other features
--Python shell window (a.k.a interactive interpreter)
--debugger (not complete, but you can set breakpoints, view and step)
-
-Menus:
-
-IDLE has two window types the Shell window and the Editor window. It is
-possible to have multiple editor windows simultaneously. IDLE's
-menus dynamically change based on which window is currently selected. Each menu
-documented below indicates which window type it is associated with. 
-
-File Menu (Shell and Editor):
-
-        New File         -- Create a new file editing window
-        Open...          -- Open an existing file

-
-        Save As...       -- Save current window to new file, which becomes
-                            the associated file
-        Save Copy As...  -- Save current window to different file
-                            without changing the associated file

-** TIPS **
-==========
-
-Additional Help Sources:
-
-        Windows users can Google on zopeshelf.chm to access Zope help files in
-        the Windows help format.  The Additional Help Sources feature of the
-        configuration GUI supports .chm, along with any other filetypes
-        supported by your browser.  Supply a Menu Item title, and enter the
-        location in the Help File Path slot of the New Help Source dialog.  Use
-        http:// and/or www. to identify external URLs, or download the file and
-        browse for its path on your machine using the Browse button.
-
-        All users can access the extensive sources of help, including
-        tutorials, available at docs.python.org.  Selected URLs can be added
-        or removed from the Help menu at any time using Configure IDLE.
-
-Basic editing and navigation:
-
-        Backspace deletes char to the left; DEL deletes char to the right.
-        Control-backspace deletes word left, Control-DEL deletes word right.
-        Arrow keys and Page Up/Down move around.
-        Control-left/right Arrow moves by words in a strange but useful way.
-        Home/End go to begin/end of line.
-        Control-Home/End go to begin/end of file.
-        Some useful Emacs bindings are inherited from Tcl/Tk:
-                Control-a     beginning of line
-                Control-e     end of line
-                Control-k     kill line (but doesn't put it in clipboard)
-                Control-l     center window around the insertion point
-        Standard keybindings (like Control-c to copy and Control-v to
-        paste) may work.  Keybindings are selected in the Configure IDLE
-        dialog.
-
-Automatic indentation:
-
-        After a block-opening statement, the next line is indented by 4 spaces
-        (in the Python Shell window by one tab).  After certain keywords
-        (break, return etc.) the next line is dedented.  In leading
-        indentation, Backspace deletes up to 4 spaces if they are there.  Tab
-        inserts spaces (in the Python Shell window one tab), number depends on
-        Indent Width. Currently tabs are restricted to four spaces due
-        to Tcl/Tk limitations.
-
-        See also the indent/dedent region commands in the edit menu.
-
-Completions:
-
-        Completions are supplied for functions, classes, and attributes of
-        classes, both built-in and user-defined.  Completions are also provided
-        for filenames.
-
-        The AutoCompleteWindow (ACW) will open after a predefined delay
-        (default is two seconds) after a '.' or (in a string) an os.sep is
-        typed.  If after one of those characters (plus zero or more other
-        characters) a tab is typed the ACW will open immediately if a possible
-        continuation is found.
-
-        If there is only one possible completion for the characters entered, a
-        tab will supply that completion without opening the ACW.
-
-        'Show Completions' will force open a completions window, by default the
-        Control-space keys will open a completions window.  In an empty
-        string, this will contain the files in the current directory.  On a
-        blank line, it will contain the built-in and user-defined functions and
-        classes in the current name spaces, plus any modules imported.  If some
-        characters have been entered, the ACW will attempt to be more specific.
-
-        If string of characters is typed, the ACW selection will jump to the
-        entry most closely matching those characters. Entering a tab will cause
-        the longest non-ambiguous match to be entered in the Edit window or
-        Shell.  Two tabs in a row will supply the current ACW selection, as
-        will return or a double click.  Cursor keys, Page Up/Down, mouse
-        selection, and the scroll wheel all operate on the ACW.
-
-        "Hidden" attributes can be accessed by typing the beginning of hidden
-        name after a '.',  e.g. '_'.  This allows access to modules with
-        '__all__' set, or to class-private attributes.
-
-        Completions and the 'Expand Word' facility can save a lot of typing!
-
-        Completions are currently limited to those in the namespaces.  Names in
-        an Editor window which are not via __main__ or sys.modules will not be
-        found.  Run the module once with your imports to correct this
-        situation.  Note that IDLE itself places quite a few modules in
-        sys.modules, so much can be found by default, e.g. the re module.
-
-        If you don't like the ACW popping up unbidden, simply make the delay
-        longer or disable the extension.  Or another option is the delay could
-        be set to zero. Another alternative to preventing ACW popups is to
-        disable the call tips extension.
-
-Python Shell window:
-
-        Control-c interrupts executing command.
-        Control-d sends end-of-file; closes window if typed at >>> prompt.
-        Alt-/ expand word is also useful to reduce typing.
-
-    Command history:
-
-        Alt-p retrieves previous command matching what you have typed. On OS X
-        use Control-p.
-        Alt-n retrieves next. On OS X use Control-n.
-        Return while cursor is on a previous command retrieves that command.
-
-    Syntax colors:
-
-        The coloring is applied in a background "thread", so you may
-        occasionally see uncolorized text.  To change the color
-        scheme, use the Configure IDLE / Highlighting dialog.
-
-    Python default syntax colors:
-
-        Keywords        orange
-        Builtins        royal purple
-        Strings         green
-        Comments        red
-        Definitions     blue
-
-    Shell default colors:
-
-        Console output  brown
-        stdout          blue
-        stderr          red
-        stdin           black
-
-Other preferences:
-
-        The font preferences, highlighting, keys, and general preferences can
-        be changed via the Configure IDLE menu option.  Be sure to note that
-        keys can be user defined, IDLE ships with four built in key sets. In
-        addition a user can create a custom key set in the Configure IDLE
-        dialog under the keys tab.
-
-Command line usage:
-
-        Enter idle -h at the command prompt to get a usage message.
-
-        idle.py [-c command] [-d] [-e] [-s] [-t title] [arg] ...
-
-        -c command  run this command
-        -d          enable debugger
-        -e          edit mode; arguments are files to be edited
-        -s          run $IDLESTARTUP or $PYTHONSTARTUP first
-        -t title    set title of shell window
-
-        If there are arguments:
-        1. If -e is used, arguments are files opened for editing and sys.argv
-           reflects the arguments passed to IDLE itself.
-        2. Otherwise, if -c is used, all arguments are placed in
-           sys.argv[1:...], with sys.argv[0] set to -c.
-        3. Otherwise, if neither -e nor -c is used, the first argument is a
-           script which is executed with the remaining arguments in
-           sys.argv[1:...]  and sys.argv[0] set to the script name.  If the
-           script name is -, no script is executed but an interactive Python
-           session is started; the arguments are still available in sys.argv.
-
-Running without a subprocess: (DEPRECATED in Python 3.4 see Issue 16123)
-
-        If IDLE is started with the -n command line switch it will run in a
-        single process and will not create the subprocess which runs the RPC
-        Python execution server.  This can be useful if Python cannot create
-        the subprocess or the RPC socket interface on your platform.  However,
-        in this mode user code is not isolated from IDLE itself.  Also, the
-        environment is not restarted when Run/Run Module (F5) is selected.  If
-        your code has been modified, you must reload() the affected modules and
-        re-import any specific items (e.g. from foo import baz) if the changes
-        are to take effect.  For these reasons, it is preferable to run IDLE
-        with the default subprocess if at all possible.
-
-Extensions:
-
-        IDLE contains an extension facility.  See the beginning of
-        config-extensions.def in the idlelib directory for further information.
-        The default extensions are currently:
-
-                FormatParagraph
-                AutoExpand
-                ZoomHeight
-                ScriptBinding
-                CallTips
-                ParenMatch
-                AutoComplete
-                CodeContext
