+      extra_compile_args : [string]
+        any extra platform- and compiler-specific information to use
+        when compiling the source files in 'sources'.  For platforms and
+        compilers where "command line" makes sense, this is typically a
+        list of command-line arguments, but for other platforms it could
+        be anything.
+      extra_link_args : [string]
+        any extra platform- and compiler-specific information to use
+        when linking object files together to create the extension (or
+        to create a new static Python interpreter).  Similar
+        interpretation as for 'extra_compile_args'.
+      export_symbols : [string]
+        list of symbols to be exported from a shared extension.  Not
+        used on all platforms, and not generally necessary for Python
+        extensions, which typically export exactly one symbol: "init" +
+        extension_name.
+      swig_opts : [string]
+        any extra options to pass to SWIG if a source file has the .i
+        extension.
+      depends : [string]
+        list of files that the extension depends on
+      language : string
+        extension language (i.e. "c", "c++", "objc"). Will be detected
+        from the source extensions if not provided.
+      optional : boolean
+        specifies that a build failure in the extension should not abort the
+        build process, but simply not install the failing extension.

+       recommended that you supply at least 'filename', so that TextFile
+       can include it in warning messages.  If 'file' is not supplied,
+       TextFile creates its own using 'io.open()'.
+
+       The options are all boolean, and affect the value returned by
+       'readline()':
+         strip_comments [default: true]
+           strip from "#" to end-of-line, as well as any whitespace
+           leading up to the "#" -- unless it is escaped by a backslash
+         lstrip_ws [default: false]
+           strip leading whitespace from each line before returning it
+         rstrip_ws [default: true]
+           strip trailing whitespace (including line terminator!) from
+           each line before returning it
+         skip_blanks [default: true}
+           skip lines that are empty *after* stripping comments and
+           whitespace.  (If both lstrip_ws and rstrip_ws are false,
+           then some lines may consist of solely whitespace: these will
+           *not* be skipped, even if 'skip_blanks' is true.)
+         join_lines [default: false]
+           if a backslash is the last non-newline character on a line
+           after stripping comments and whitespace, join the following line
+           to it to form one "logical line"; if N consecutive lines end
+           with a backslash, then N+1 physical lines will be joined to
+           form one logical line.
+         collapse_join [default: false]
+           strip leading whitespace from lines that are joined to their
+           predecessor; only matters if (join_lines and not lstrip_ws)
+         errors [default: 'strict']
+           error handler used to decode the file content
+
+       Note that since 'rstrip_ws' can strip the trailing newline, the
+       semantics of 'readline()' must differ from those of the builtin file
+       object's 'readline()' method!  In particular, 'readline()' returns
+       None for end-of-file: an empty string might just be a blank line (or
+       an all-whitespace line), if 'rstrip_ws' is true but 'skip_blanks' is

+IDLE History
+============
+
+This file contains the release messages for previous IDLE releases.
+As you read on you go back to the dark ages of IDLE's history.
+
+
+What's New in IDLEfork 0.8.1?
+=============================
+
+*Release date: 22-Jul-2001*
+
+- New tarball released as a result of the 'revitalisation' of the IDLEfork
+  project.
+
+- This release requires python 2.1 or better. Compatibility with earlier
+  versions of python (especially ancient ones like 1.5x) is no longer a
+  priority in IDLEfork development.
+
+- This release is based on a merging of the earlier IDLE fork work with current
+  cvs IDLE (post IDLE version 0.8), with some minor additional coding by Kurt
+  B. Kaiser and Stephen M. Gava.
+
+- This release is basically functional but also contains some known breakages,
+  particularly with running things from the shell window. Also the debugger is
+  not working, but I believe this was the case with the previous IDLE fork
+  release (0.7.1) as well.
+
+- This release is being made now to mark the point at which IDLEfork is
+  launching into a new stage of development.
+
+- IDLEfork CVS will now be branched to enable further development and
+  exploration of the two "execution in a remote process" patches submitted by
+  David Scherer (David's is currently in IDLEfork) and GvR, while stabilisation
+  and development of less heavyweight improvements (like user customisation)
+  can continue on the trunk.
+
+
+What's New in IDLEfork 0.7.1?
+==============================
+
+*Release date: 15-Aug-2000*
+
+- First project tarball released.
+
+- This was the first release of IDLE fork, which at this stage was a
+  combination of IDLE 0.5 and the VPython idle fork, with additional changes
+  coded by David Scherer, Peter Schneider-Kamp and Nicholas Riley.
+
+
+
+IDLEfork 0.7.1 - 29 May 2000
+-----------------------------
+
+   David Scherer  <dscherer@cmu.edu>
+
+- This is a modification of the CVS version of IDLE 0.5, updated as of
+  2000-03-09.  It is alpha software and might be unstable.  If it breaks, you
+  get to keep both pieces.
+
+- If you have problems or suggestions, you should either contact me or post to
+  the list at http://www.python.org/mailman/listinfo/idle-dev (making it clear
+  that you are using this modified version of IDLE).
+
+- Changes:
+
+  - The ExecBinding module, a replacement for ScriptBinding, executes programs
+    in a separate process, piping standard I/O through an RPC mechanism to an
+    OnDemandOutputWindow in IDLE.  It supports executing unnamed programs
+    (through a temporary file).  It does not yet support debugging.
+
+  - When running programs with ExecBinding, tracebacks will be clipped to
+    exclude system modules.  If, however, a system module calls back into the
+    user program, that part of the traceback will be shown.
+
+  - The OnDemandOutputWindow class has been improved.  In particular, it now
+    supports a readline() function used to implement user input, and a
+    scroll_clear() operation which is used to hide the output of a previous run
+    by scrolling it out of the window.
+
+  - Startup behavior has been changed.  By default IDLE starts up with just a
+    blank editor window, rather than an interactive window.  Opening a file in
+    such a blank window replaces the (nonexistent) contents of that window
+    instead of creating another window.  Because of the need to have a
+    well-known port for the ExecBinding protocol, only one copy of IDLE can be
+    running.  Additional invocations use the RPC mechanism to report their
+    command line arguments to the copy already running.
+
+  - The menus have been reorganized.  In particular, the excessively large
+    'edit' menu has been split up into 'edit', 'format', and 'run'.
+
+  - 'Python Documentation' now works on Windows, if the win32api module is
+    present.
+
+  - A few key bindings have been changed: F1 now loads Python Documentation
+    instead of the IDLE help; shift-TAB is now a synonym for unindent.
+
+- New modules:
+
+  ExecBinding.py         Executes program through loader
+  loader.py              Bootstraps user program
+  protocol.py            RPC protocol
+  Remote.py              User-process interpreter
+  spawn.py               OS-specific code to start programs
+
+- Files modified:
+
+  autoindent.py          ( bindings tweaked )
+  bindings.py            ( menus reorganized )
+  config.txt             ( execbinding enabled )
+  editorwindow.py        ( new menus, fixed 'Python Documentation' )
+  filelist.py            ( hook for "open in same window" )
+  formatparagraph.py     ( bindings tweaked )
+  idle.bat               ( removed absolute pathname )
+  idle.pyw               ( weird bug due to import with same name? )
+  iobinding.py           ( open in same window, EOL convention )
+  keydefs.py             ( bindings tweaked )
+  outputwindow.py        ( readline, scroll_clear, etc )
+  pyshell.py             ( changed startup behavior )
+  readme.txt             ( <Recursion on file with id=1234567> )
+
+
+
+IDLE 0.5 - February 2000 - Release Notes
+----------------------------------------
+
+This is an early release of IDLE, my own attempt at a Tkinter-based
+IDE for Python.
+
+(For a more detailed change log, see the file ChangeLog.)
+
+FEATURES
+
+IDLE has the following features:
+
+- coded in 100% pure Python, using the Tkinter GUI toolkit (i.e. Tcl/Tk)
+
+- cross-platform: works on Windows and Unix (on the Mac, there are
+currently problems with Tcl/Tk)
+
+- multi-window text editor with multiple undo, Python colorizing
+and many other features, e.g. smart indent and call tips
+
+- Python shell window (a.k.a. interactive interpreter)
+
+- debugger (not complete, but you can set breakpoints, view  and step)
+
+USAGE
+
+The main program is in the file "idle.py"; on Unix, you should be able
+to run it by typing "./idle.py" to your shell.  On Windows, you can
+run it by double-clicking it; you can use idle.pyw to avoid popping up
+a DOS console.  If you want to pass command line arguments on Windows,
+use the batch file idle.bat.
+
+Command line arguments: files passed on the command line are executed,
+not opened for editing, unless you give the -e command line option.
+Try "./idle.py -h" to see other command line options.
+
+IDLE requires Python 1.5.2, so it is currently only usable with a
+Python 1.5.2 distribution.  (An older version of IDLE is distributed
+with Python 1.5.2; you can drop this version on top of it.)
+
+COPYRIGHT
+
+IDLE is covered by the standard Python copyright notice
+(http://www.python.org/doc/Copyright.html).
+
+
+New in IDLE 0.5 (2/15/2000)
+---------------------------
+
+Tons of stuff, much of it contributed by Tim Peters and Mark Hammond:
+
+- Status bar, displaying current line/column (Moshe Zadka).
+
+- Better stack viewer, using tree widget.  (XXX Only used by Stack
+Viewer menu, not by the debugger.)
+
+- Format paragraph now recognizes Python block comments and reformats
+them correctly (MH)
+
+- New version of pyclbr.py parses top-level functions and understands
+much more of Python's syntax; this is reflected in the class and path
+browsers (TP)
+
+- Much better auto-indent; knows how to indent the insides of
+multi-line statements (TP)
+
+- Call tip window pops up when you type the name of a known function
+followed by an open parenthesis.  Hit ESC or click elsewhere in the
+window to close the tip window (MH)
+
+- Comment out region now inserts ## to make it stand out more (TP)
+
+- New path and class browsers based on a tree widget that looks
+familiar to Windows users
+
+- Reworked script running commands to be more intuitive: I/O now
+always goes to the *Python Shell* window, and raw_input() works
+correctly.  You use F5 to import/reload a module: this adds the module
+name to the __main__ namespace.  You use Control-F5 to run a script:
+this runs the script *in* the __main__ namespace.  The latter also
+sets sys.argv[] to the script name
+
+
+New in IDLE 0.4 (4/7/99)
+------------------------
+
+Most important change: a new menu entry "File -> Path browser", shows
+a 4-column hierarchical browser which lets you browse sys.path,
+directories, modules, and classes.  Yes, it's a superset of the Class
+browser menu entry.  There's also a new internal module,
+MultiScrolledLists.py, which provides the framework for this dialog.
+
+
+New in IDLE 0.3 (2/17/99)
+-------------------------
+
+Most important changes:
+
+- Enabled support for running a module, with or without the debugger.
+Output goes to a new window.  Pressing F5 in a module is effectively a
+reload of that module; Control-F5 loads it under the debugger.
+
+- Re-enable tearing off the Windows menu, and make a torn-off Windows
+menu update itself whenever a window is opened or closed.
+
+- Menu items can now be have a checkbox (when the menu label starts
+with "!"); use this for the Debugger and "Auto-open stack viewer"
+(was: JIT stack viewer) menu items.
+
+- Added a Quit button to the Debugger API.
+
+- The current directory is explicitly inserted into sys.path.
+
+- Fix the debugger (when using Python 1.5.2b2) to use canonical
+filenames for breakpoints, so these actually work.  (There's still a
+lot of work to be done to the management of breakpoints in the
+debugger though.)
+
+- Closing a window that is still colorizing now actually works.
+
+- Allow dragging of the separator between the two list boxes in the
+class browser.
+
+- Bind ESC to "close window" of the debugger, stack viewer and class
+browser.  It removes the selection highlighting in regular text
+windows.  (These are standard Windows conventions.)
+
+
+New in IDLE 0.2 (1/8/99)
+------------------------
+
+Lots of changes; here are the highlights:
+
+General:
+
+- You can now write and configure your own IDLE extension modules; see
+extend.txt.
+
+
+File menu:
+
+The command to open the Python shell window is now in the File menu.
+
+
+Edit menu:
+
+New Find dialog with more options; replace dialog; find in files dialog.
+
+Commands to tabify or untabify a region.
+
+Command to format a paragraph.
+
+
+Debug menu:
+
+JIT (Just-In-Time) stack viewer toggle -- if set, the stack viewer
+automaticall pops up when you get a traceback.
+
+Windows menu:
+
+Zoom height -- make the window full height.
+
+
+Help menu:
+
+The help text now show up in a regular window so you can search and
+even edit it if you like.
+
+
+
+IDLE 0.1 was distributed with the Python 1.5.2b1 release on 12/22/98.

+What's New in IDLE 2.7? (Merged into 3.1 before 2.7 release.)
+=======================
+*Release date: XX-XXX-2010*
+
+- idle.py modified and simplified to better support developing experimental
+  versions of IDLE which are not installed in the standard location.
+
+- OutputWindow/PyShell right click menu "Go to file/line" wasn't working with
+  file paths containing spaces.  Bug 5559.
+
+- Windows: Version string for the .chm help file changed, file not being
+  accessed  Patch 5783 Guilherme Polo
+
+- Allow multiple IDLE GUI/subprocess pairs to exist simultaneously. Thanks to
+  David Scherer for suggesting the use of an ephemeral port for the GUI.
+  Patch 1529142 Weeble.
+
+- Remove port spec from run.py and fix bug where subprocess fails to
+  extract port from command line when warnings are present.
+
+- Tk 8.5 Text widget requires 'wordprocessor' tabstyle attr to handle
+  mixed space/tab properly. Issue 5129, patch by Guilherme Polo.
+
+- Issue #3549: On MacOS the preferences menu was not present
+
+- IDLE would print a "Unhandled server exception!" message when internal
+  debugging is enabled.
+
+- Issue #4455: IDLE failed to display the windows list when two windows have
+  the same title.
+
+- Issue #4383: When IDLE cannot make the connection to its subprocess, it would
+  fail to properly display the error message.
+
+- help() was not paging to the shell.  Issue1650.
+
+- CodeContext was not importing.
+
+- Corrected two 3.0 compatibility errors reported by Mark Summerfield:
+  http://mail.python.org/pipermail/python-3000/2007-December/011491.html
+
+- Shell was not colorizing due to bug introduced at r57998,  Bug 1586.
+
+- Issue #1585: IDLE uses non-existent xrange() function.
+

+
+- Strings became Unicode.
+
+- CallTips module now uses the inspect module to produce the argspec.
+
+- IDLE modules now use absolute import instead of implied relative import.
+
+- atexit call replaces sys.exitfunc.  The functionality of delete-exitfunc flag
+  in config-main.cfg remains unchanged: if set, registered exit functions will
+  be cleared before IDLE exits.
+
+
+What's New in IDLE 2.6
+======================
+*Release date: 01-Oct-2008*, merged into 3.0 releases detailed above (3.0rc2)
+
+- Issue #2665: On Windows, an IDLE installation upgraded from an old version
+  would not start if a custom theme was defined.
+
+- Home / Control-A toggles between left margin and end of leading white
+  space.  issue1196903, patch by Jeff Shute.
+
+- Improved AutoCompleteWindow logic.  issue2062, patch by Tal Einat.
+
+- Autocompletion of filenames now support alternate separators, e.g. the
+  '/' char on Windows.  issue2061 Patch by Tal Einat.
+
+- Configured selection highlighting colors were ignored; updating highlighting
+  in the config dialog would cause non-Python files to be colored as if they
+  were Python source; improve use of ColorDelagator.  Patch 1334. Tal Einat.
+
+- ScriptBinding event handlers weren't returning 'break'. Patch 2050, Tal Einat
+
+- There was an error on exit if no sys.exitfunc was defined. Issue 1647.
+
+- Could not open files in .idlerc directory if latter was hidden on Windows.
+  Issue 1743, Issue 1862.
+
+- Configure Dialog: improved layout for keybinding.  Patch 1457 Tal Einat.
+
+- tabpage.py updated: tabbedPages.py now supports multiple dynamic rows
+  of tabs.  Patch 1612746 Tal Einat.
+
+- Add confirmation dialog before printing.  Patch 1717170 Tal Einat.
+
+- Show paste position if > 80 col.  Patch 1659326 Tal Einat.

+  Patch 1225 Tal Einat (reworked from IDLE-Spoon).
+
+- configDialog cleanup. Patch 1730217 Tal Einat.
+
+- textView cleanup. Patch 1718043 Tal Einat.
+
+- Clean up EditorWindow close.
+
+- Patch 1693258: Fix for duplicate "preferences" menu-OS X. Backport of r56204.
+
+- OSX: Avoid crash for those versions of Tcl/Tk which don't have a console
+
+- Bug in idlelib.MultiCall: Options dialog was crashing IDLE if there was an
+  option in config-extensions w/o a value. Patch #1672481, Tal Einat
+
+- Corrected some bugs in AutoComplete.  Also, Page Up/Down in ACW implemented;
+  mouse and cursor selection in ACWindow implemented; double Tab inserts
+  current selection and closes ACW (similar to double-click and Return); scroll
+  wheel now works in ACW.  Added AutoComplete instructions to IDLE Help.
+
+- AutoCompleteWindow moved below input line, will move above if there
+  isn't enough space.  Patch 1621265 Tal Einat
+
+- Calltips now 'handle' tuples in the argument list (display '<tuple>' :)
+  Suggested solution by Christos Georgiou, Bug 791968.
+
+- Add 'raw' support to configHandler. Patch 1650174 Tal Einat.

+
+- Patch #1362975: Rework CodeContext indentation algorithm to
+  avoid hard-coding pixel widths.
+
+- Bug #813342: Start the IDLE subprocess with -Qnew if the parent
+  is started with that option.
+
+- Honor the "Cancel" action in the save dialog (Debian bug #299092)
+
+- Some syntax errors were being caught by tokenize during the tabnanny
+  check, resulting in obscure error messages.  Do the syntax check
+  first.  Bug 1562716, 1562719
+
+- IDLE's version number takes a big jump to match the version number of
+  the Python release of which it's a part.
+
+
+What's New in IDLE 1.2?
+=======================
+*Release date: 19-SEP-2006*
+
+- File menu hotkeys: there were three 'p' assignments.  Reassign the
+  'Save Copy As' and 'Print' hotkeys to 'y' and 't'.  Change the
+  Shell hotkey from 's' to 'l'.
+
+- IDLE honors new quit() and exit() commands from site.py Quitter() object.
+  Patch 1540892, Jim Jewett
+
+- The 'with' statement is now a Code Context block opener.
+  Patch 1540851, Jim Jewett
+
+- Retrieval of previous shell command was not always preserving indentation
+  (since 1.2a1) Patch 1528468 Tal Einat.
+
+- Changing tokenize (39046) to detect dedent broke tabnanny check (since 1.2a1)
+
+- ToggleTab dialog was setting indent to 8 even if cancelled (since 1.2a1).
+
+- When used w/o subprocess, all exceptions were preceded by an error
+  message claiming they were IDLE internal errors (since 1.2a1).
+
+- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
+
+- Bug #1517990: IDLE keybindings on MacOS X now work correctly
+
+- Bug #1517996: IDLE now longer shows the default Tk menu when a
+  path browser, class browser or debugger is the frontmost window on MacOS X
+
+- EditorWindow.test() was failing.  Bug 1417598
+
+- EditorWindow failed when used stand-alone if sys.ps1 not set.
+  Bug 1010370 Dave Florek
+
+- Tooltips failed on new-syle class __init__ args.  Bug 1027566 Loren Guthrie
+
+- Avoid occasional failure to detect closing paren properly.
+  Patch 1407280 Tal Einat
+
+- Rebinding Tab key was inserting 'tab' instead of 'Tab'.  Bug 1179168.
+
+- Colorizer now handles #<builtin> correctly, also unicode strings and
+  'as' keyword in comment directly following import command. Closes 1325071.
+  Patch 1479219 Tal Einat
+
+- Patch #1162825: Support non-ASCII characters in IDLE window titles.
+
+- Source file f.flush() after writing; trying to avoid lossage if user
+  kills GUI.
+
+- Options / Keys / Advanced dialog made functional.  Also, allow binding
+  of 'movement' keys.
+
+- 'syntax' patch adds improved calltips and a new class attribute listbox.
+  MultiCall module allows binding multiple actions to an event.
+  Patch 906702 Noam Raphael
+
+- Better indentation after first line of string continuation.
+  IDLEfork Patch 681992, Noam Raphael
+
+- Fixed CodeContext alignment problem, following suggestion from Tal Einat.
+
+- Increased performance in CodeContext extension  Patch 936169 Noam Raphael
+
+- Mac line endings were incorrect when pasting code from some browsers
+  when using X11 and the Fink distribution.  Python Bug 1263656.
+
+- <Enter> when cursor is on a previous command retrieves that command.  Instead
+  of replacing the input line, the previous command is now appended to the
+  input line. Indentation is preserved, and undo is enabled.
+  Patch 1196917  Jeff Shute
+
+- Clarify "tab/space" Error Dialog and "Tab Width" Dialog associated with
+  the Untabify command.
+
+- Corrected "tab/space" Error Dialog to show correct menu for Untabify.
+  Patch 1196980 Jeff Shute
+
+- New files are colorized by default, and colorizing is removed when
+  saving as non-Python files. Patch 1196895 Jeff Shute
+  Closes Python Bugs 775012 and 800432, partial fix IDLEfork 763524
+
+- Improve subprocess link error notification.
+
+- run.py: use Queue's blocking feature instead of sleeping in the main
+  loop.  Patch # 1190163 Michiel de Hoon
+
+- Add config-main option to make the 'history' feature non-cyclic.
+  Default remains cyclic.  Python Patch 914546 Noam Raphael.
+
+- Removed ability to configure tabs indent from Options dialog.  This 'feature'
+  has never worked and no one has complained.  It is still possible to set a
+  default tabs (v. spaces) indent 'manually' via config-main.def (or to turn on
+  tabs for the current EditorWindow via the Format menu) but IDLE will
+  encourage indentation via spaces.
+
+- Enable setting the indentation width using the Options dialog.
+  Bug # 783877
+
+- Add keybindings for del-word-left and del-word-right.
+
+- Discourage using an indent width other than 8 when using tabs to indent
+  Python code.
+
+- Restore use of EditorWindow.set_indentation_params(), was dead code since
+  Autoindent was merged into EditorWindow.  This allows IDLE to conform to the
+  indentation width of a loaded file.  (But it still will not switch to tabs
+  even if the file uses tabs.)  Any change in indent width is local to that
+  window.
+
+- Add Tabnanny check before Run/F5, not just when Checking module.
+
+- If an extension can't be loaded, print warning and skip it instead of
+  erroring out.
+
+- Improve error handling when .idlerc can't be created (warn and exit).
+
+- The GUI was hanging if the shell window was closed while a raw_input()
+  was pending.  Restored the quit() of the readline() mainloop().
+  http://mail.python.org/pipermail/idle-dev/2004-December/002307.html
+
+- The remote procedure call module rpc.py can now access data attributes of
+  remote registered objects.  Changes to these attributes are local, however.
+
+
+What's New in IDLE 1.1?
+=======================
+*Release date: 30-NOV-2004*
+
+- On OpenBSD, terminating IDLE with ctrl-c from the command line caused a
+  stuck subprocess MainThread because only the SocketThread was exiting.
+
+- Saving a Keyset w/o making changes (by using the "Save as New Custom Key Set"
+  button) caused IDLE to fail on restart (no new keyset was created in
+  config-keys.cfg).  Also true for Theme/highlights.  Python Bug 1064535.
+
+- A change to the linecache.py API caused IDLE to exit when an exception was
+  raised while running without the subprocess (-n switch).  Python Bug 1063840.
+
+- When paragraph reformat width was made configurable, a bug was
+  introduced that caused reformatting of comment blocks to ignore how
+  far the block was indented, effectively adding the indentation width
+  to the reformat width.  This has been repaired, and the reformat
+  width is again a bound on the total width of reformatted lines.
+
+- Improve keyboard focus binding, especially in Windows menu.  Improve
+  window raising, especially in the Windows menu and in the debugger.
+  IDLEfork 763524.
+
+- If user passes a non-existent filename on the commandline, just
+  open a new file, don't raise a dialog.  IDLEfork 854928.
+
+- EditorWindow.py was not finding the .chm help file on Windows.  Typo
+  at Rev 1.54.  Python Bug 990954
+
+- checking sys.platform for substring 'win' was breaking IDLE docs on Mac
+  (darwin).  Also, Mac Safari browser requires full file:// URIs.  SF 900580.
+
+- Redirect the warning stream to the shell during the ScriptBinding check of
+  user code and format the warning similarly to an exception for both that
+  check and for runtime warnings raised in the subprocess.
+
+- CodeContext hint pane visibility state is now persistent across sessions.
+  The pane no longer appears in the shell window.  Added capability to limit
+  extensions to shell window or editor windows.  Noam Raphael addition
+  to Patch 936169.
+
+- Paragraph reformat width is now a configurable parameter in the
+  Options GUI.
+
+- New Extension: CodeContext.  Provides block structuring hints for code
+  which has scrolled above an edit window. Patch 936169 Noam Raphael.
+
+- If nulls somehow got into the strings in recent-files.lst
+  EditorWindow.update_recent_files_list() was failing.  Python Bug 931336.
+
+- If the normal background is changed via Configure/Highlighting, it will
+  update immediately, thanks to the previously mentioned patch by Nigel Rowe.
+
+- Add a highlight theme for builtin keywords.  Python Patch 805830 Nigel Rowe
+  This also fixed IDLEfork bug [ 693418 ] Normal text background color not
+  refreshed and Python bug [897872 ] Unknown color name on HP-UX
+
+- rpc.py:SocketIO - Large modules were generating large pickles when downloaded
+  to the execution server.  The return of the OK response from the subprocess
+  initialization was interfering and causing the sending socket to be not
+  ready.  Add an IO ready test to fix this.  Moved the polling IO ready test
+  into pollpacket().
+
+- Fix typo in rpc.py, s/b "pickle.PicklingError" not "pickle.UnpicklingError".
+
+- Added a Tk error dialog to run.py inform the user if the subprocess can't
+  connect to the user GUI process.  Added a timeout to the GUI's listening
+  socket.  Added Tk error dialogs to PyShell.py to announce a failure to bind
+  the port or connect to the subprocess.  Clean up error handling during
+  connection initiation phase.  This is an update of Python Patch 778323.
+
+- Print correct exception even if source file changed since shell was
+  restarted.  IDLEfork Patch 869012 Noam Raphael
+
+- Keybindings with the Shift modifier now work correctly.  So do bindings which
+  use the Space key.  Limit unmodified user keybindings to the function keys.
+  Python Bug 775353, IDLEfork Bugs 755647, 761557
+
+- After an exception, run.py was not setting the exception vector. Noam
+  Raphael suggested correcting this so pdb's postmortem pm() would work.
+  IDLEfork Patch 844675
+
+- IDLE now does not fail to save the file anymore if the Tk buffer is not a
+  Unicode string, yet eol_convention is.  Python Bugs 774680, 788378
+
+- IDLE didn't start correctly when Python was installed in "Program Files" on
+  W2K and XP.  Python Bugs 780451, 784183
+
+- config-main.def documentation incorrectly referred to idle- instead of
+  config-  filenames.  SF 782759  Also added note about .idlerc location.
+
+
+What's New in IDLE 1.0?
+=======================
+*Release date: 29-Jul-2003*
+
+- Added a banner to the shell discussing warnings possibly raised by personal
+  firewall software.  Added same comment to README.txt.
+
+- Calltip error when docstring was None  Python Bug 775541
+
+- Updated extend.txt, help.txt, and config-extensions.def to correctly
+  reflect the current status of the configuration system.  Python Bug 768469
+
+- Fixed: Call Tip Trimming May Loop Forever. Python Patch 769142 (Daniels)
+
+- Replaced apply(f, args, kwds) with f(*args, **kwargs) to improve performance
+  Python Patch 768187
+
+- Break or continue statements outside a loop were causing IDLE crash
+  Python Bug 767794
+
+- Convert Unicode strings from readline to IOBinding.encoding.  Also set
+  sys.std{in|out|err}.encoding, for both the local and the subprocess case.
+  SF IDLEfork patch 682347.
+
+- Extend AboutDialog.ViewFile() to support file encodings.  Make the CREDITS
+  file Latin-1.
+
+- Updated the About dialog to reflect re-integration into Python.  Provide
+  buttons to display Python's NEWS, License, and Credits, plus additional
+  buttons for IDLE's README and NEWS.
+
+- TextViewer() now has a third parameter which allows inserting text into the
+  viewer instead of reading from a file.
+
+- (Created the .../Lib/idlelib directory in the Python CVS, which is a clone of
+  IDLEfork modified to install in the Python environment.  The code in the
+  interrupt module has been moved to thread.interrupt_main(). )
+
+- Printing the Shell window was failing if it was not saved first SF 748975
+
+- When using the Search in Files dialog, if the user had a selection
+  highlighted in his Editor window, insert it into the dialog search field.
+
+- The Python Shell entry was disappearing from the Windows menu.
+
+- Update the Windows file list when a file name change occurs
+
+- Change to File / Open Module: always pop up the dialog, using the current
+  selection as the default value.  This is easier to use habitually.
+
+- Avoided a problem with starting the subprocess when 'localhost' doesn't
+  resolve to the user's loopback interface.  SF 747772
+
+- Fixed an issue with highlighted errors never de-colorizing.  SF 747677.  Also
+  improved notification of Tabnanny Token Error.
+
+- File / New will by default save in the directory of the Edit window from
+  which it was initiated.  SF 748973 Guido van Rossum patch.
+
+
+What's New in IDLEfork 0.9b1?
+=============================
+*Release date: 02-Jun-2003*
+
+- The current working directory of the execution environment (and shell
+  following completion of execution) is now that of the module being run.
+
+- Added the delete-exitfunc option to config-main.def.  (This option is not
+  included in the Options dialog.)  Setting this to True (the default) will
+  cause IDLE to not run sys.exitfunc/atexit when the subprocess exits.
+
+- IDLE now preserves the line ending codes when editing a file produced on
+  a different platform. SF 661759,  SF 538584
+
+- Reduced default editor font size to 10 point and increased window height
+  to provide a better initial impression on Windows.
+
+- Options / Fonts/Tabs / Set Base Editor Font: List box was not highlighting
+  the default font when first installed on Windows.  SF 661676
+
+- Added Autosave feature: when user runs code from edit window, if the file
+  has been modified IDLE will silently save it if Autosave is enabled.  The
+  option is set in the Options dialog, and the default is to prompt the
+  user to save the file.   SF 661318 Bruce Sherwood patch.
+
+- Improved the RESTART annotation in the shell window when the user restarts
+  the shell while it is generating output.  Also improved annotation when user
+  repeatedly hammers the Ctrl-F6 restart.
+
+- Allow IDLE to run when not installed and cwd is not the IDLE directory
+  SF Patch 686254 "Run IDLEfork from any directory without set-up" - Raphael
+
+- When a module is run from an EditorWindow: if its directory is not in
+  sys.path, prepend it.  This allows the module to import other modules in
+  the same directory.  Do the same for a script run from the command line.
+
+- Correctly restart the subprocess if it is running user code and the user
+  attempts to run some other module or restarts the shell.  Do the same if
+  the link is broken and it is possible to restart the subprocess and re-
+  connect to the GUI.   SF RFE 661321.
+
+- Improved exception reporting when running commands or scripts from the
+  command line.
+
+- Added a -n command line switch to start IDLE without the subprocess.
+  Removed the Shell menu when running in that mode.  Updated help messages.
+
+- Added a comment to the shell startup header to indicate when IDLE is not
+  using the subprocess.
+
+- Restore the ability to run without the subprocess.  This can be important for
+  some platforms or configurations.  (Running without the subprocess allows the
+  debugger to trace through parts of IDLE itself, which may or may not be
+  desirable, depending on your point of view.  In addition, the traditional
+  reload/import tricks must be use if user source code is changed.)  This is
+  helpful for developing IDLE using IDLE, because one instance can be used to
+  edit the code and a separate instance run to test changes.  (Multiple
+  concurrent IDLE instances with subprocesses is a future feature)
+
+- Improve the error message a user gets when saving a file with non-ASCII
+  characters and no source encoding is specified.  Done by adding a dialog
+  'EncodingMessage', which contains the line to add in a fixed-font entry
+  widget, and which has a button to add that line to the file automatically.
+  Also, add a configuration option 'EditorWindow/encoding', which has three
+  possible values: none, utf-8, and locale. None is the default: IDLE will show
+  this dialog when non-ASCII characters are encountered. utf-8 means that files
+  with non-ASCII characters are saved as utf-8-with-bom. locale means that
+  files are saved in the locale's encoding; the dialog is only displayed if the
+  source contains characters outside the locale's charset.  SF 710733 - Loewis
+
+- Improved I/O response by tweaking the wait parameter in various
+  calls to signal.signal().
+
+- Implemented a threaded subprocess which allows interrupting a pass
+  loop in user code using the 'interrupt' extension.  User code runs
+  in MainThread, while the RPCServer is handled by SockThread.  This is
+  necessary because Windows doesn't support signals.
+
+- Implemented the 'interrupt' extension module, which allows a subthread
+  to raise a KeyboardInterrupt in the main thread.
+
+- Attempting to save the shell raised an error related to saving
+  breakpoints, which are not implemented in the shell
+
+- Provide a correct message when 'exit' or 'quit' are entered at the
+  IDLE command prompt  SF 695861
+
+- Eliminate extra blank line in shell output caused by not flushing
+  stdout when user code ends with an unterminated print. SF 695861
+
+- Moved responsibility for exception formatting (i.e. pruning IDLE internal
+  calls) out of rpc.py into the client and server.
+
+- Exit IDLE cleanly even when doing subprocess I/O
+
+- Handle subprocess interrupt with an RPC message.
+
+- Restart the subprocess if it terminates itself. (VPython programs do that)
+
+- Support subclassing of exceptions, including in the shell, by moving the
+  exception formatting to the subprocess.
+
+
+What's New in IDLEfork 0.9 Alpha 2?
+===================================
+*Release date: 27-Jan-2003*
+
+- Updated INSTALL.txt to claify use of the python2 rpm.
+
+- Improved formatting in IDLE Help.
+
+- Run menu: Replace "Run Script" with "Run Module".
+
+- Code encountering an unhandled exception under the debugger now shows
+  the correct traceback, with IDLE internal levels pruned out.
+
+- If an exception occurs entirely in IDLE, don't prune the IDLE internal
+  modules from the traceback displayed.
+
+- Class Browser and Path Browser now use Alt-Key-2 for vertical zoom.
+
+- IDLE icons will now install correctly even when setup.py is run from the
+  build directory
+
+- Class Browser now compatible with Python2.3 version of pyclbr.py
+
+- Left cursor move in presence of selected text now moves from left end
+  of the selection.
+
+- Add Meta keybindings to "IDLE Classic Windows" to handle reversed
+  Alt/Meta on some Linux distros.
+
+- Change default: IDLE now starts with Python Shell.
+
+- Removed the File Path from the Additional Help Sources scrolled list.
+
+- Add capability to access Additional Help Sources on the web if the
+  Help File Path begins with //http or www.  (Otherwise local path is
+  validated, as before.)
+
+- Additional Help Sources were not being posted on the Help menu in the
+  order entered.  Implement sorting the list by [HelpFiles] 'option'
+  number.
+
+- Add Browse button to New Help Source dialog.  Arrange to start in
+  Python/Doc if platform is Windows, otherwise start in current directory.
+
+- Put the Additional Help Sources directly on the Help menu instead of in
+  an Extra Help cascade menu.  Rearrange the Help menu so the Additional
+  Help Sources come last.  Update help.txt appropriately.
+
+- Fix Tk root pop-ups in configSectionNameDialog.py  and configDialog.py
+
+- Uniform capitalization in General tab of ConfigDialog, update the doc string.
+
+- Fix bug in ConfigDialog where SaveAllChangedConfig() was unexpectedly
+  deleting Additional Help Sources from the user's config file.
+
+- Make configHelpSourceEdit OK button the default and bind <Return>
+
+- Fix Tk root pop-ups in configHelpSourceEdit: error dialogs not attached
+  to parents.
+
+- Use os.startfile() to open both Additional Help and Python Help on the
+  Windows platform.  The application associated with the file type will act as
+  the viewer.  Windows help files (.chm) are now supported via the
+  Settings/General/Additional Help facility.
+
+- If Python Help files are installed locally on Linux, use them instead of
+  accessing python.org.
+
+- Make the methods for finding the Python help docs more robust, and make
+  them work in the installed configuration, also.
+
+- On the Save Before Run dialog, make the OK button the default.  One
+  less mouse action!
+
+- Add a method: EditorWindow.get_geometry() for future use in implementing
+  window location persistence.
+
+- Removed the "Help/Advice" menu entry.  Thanks, David!  We'll remember!
+
+- Change the "Classic Windows" theme's paste key to be <ctrl-v>.
+
+- Rearrange the Shell menu to put Stack Viewer entries adjacent.
+
+- Add the ability to restart the subprocess interpreter from the shell window;
+  add an associated menu entry "Shell/Restart" with binding Control-F6.  Update
+  IDLE help.
+
+- Upon a restart, annotate the shell window with a "restart boundary".  Add a
+  shell window menu "Shell/View Restart" with binding F6 to jump to the most
+  recent restart boundary.
+
+- Add Shell menu to Python Shell; change "Settings" to "Options".
+
+- Remove incorrect comment in setup.py: IDLEfork is now installed as a package.
+
+- Add INSTALL.txt, HISTORY.txt, NEWS.txt to installed configuration.
+
+- In installer text, fix reference to Visual Python, should be VPython.
+  Properly credit David Scherer.
+
+- Modified idle, idle.py, idle.pyw to improve exception handling.
+
+
+What's New in IDLEfork 0.9 Alpha 1?
+===================================
+*Release date: 31-Dec-2002*
+
+- First release of major new functionality.  For further details refer to
+  Idle-dev and/or the Sourceforge CVS.
+
+- Adapted to the Mac platform.
+
+- Overhauled the IDLE startup options and revised the idle -h help message,
+  which provides details of command line usage.
+
+- Multiple bug fixes and usability enhancements.
+
+- Introduced the new RPC implementation, which includes a debugger.  The output
+  of user code is to the shell, and the shell may be used to inspect the
+  environment after the run has finished.  (In version 0.8.1 the shell
+  environment was separate from the environment of the user code.)
+
+- Introduced the configuration GUI and a new About dialog.
+
+- Removed David Scherer's Remote Procedure Call code and replaced with Guido
+  van Rossum's.  GvR code has support for the IDLE debugger and uses the shell
+  to inspect the environment of code Run from an Edit window.  Files removed:
+  ExecBinding.py, loader.py, protocol.py, Remote.py, spawn.py

+Original IDLE todo, much of it now outdated:
+============================================
+TO DO:
+
+- improve debugger:
+    - manage breakpoints globally, allow bp deletion, tbreak, cbreak etc.
+    - real object browser
+    - help on how to use it (a simple help button will do wonders)
+    - performance?  (updates of large sets of locals are slow)
+    - better integration of "debug module"
+    - debugger should be global resource (attached to flist, not to shell)
+    - fix the stupid bug where you need to step twice
+    - display class name in stack viewer entries for methods
+    - suppress tracing through IDLE internals (e.g. print) DONE
+    - add a button to suppress through a specific module or class or method
+    - more object inspection to stack viewer, e.g. to view all array items
+- insert the initial current directory into sys.path DONE
+- default directory attribute for each window instead of only for windows
+  that have an associated filename
+- command expansion from keywords, module contents, other buffers, etc.
+- "Recent documents" menu item DONE
+- Filter region command
+- Optional horizontal scroll bar
+- more Emacsisms:
+    - ^K should cut to buffer
+    - M-[, M-] to move by paragraphs
+    - incremental search?
+- search should indicate wrap-around in some way
+- restructure state sensitive code to avoid testing flags all the time
+- persistent user state (e.g. window and cursor positions, bindings)
+- make backups when saving
+- check file mtimes at various points
+- Pluggable interface with RCS/CVS/Perforce/Clearcase
+- better help?
+- don't open second class browser on same module (nor second path browser)
+- unify class and path browsers
+- Need to define a standard way whereby one can determine one is running
+  inside IDLE (needed for Tk mainloop, also handy for $PYTHONSTARTUP)
+- Add more utility methods for use by extensions (a la get_selection)
+- Way to run command in totally separate interpreter (fork+os.system?) DONE
+- Way to find definition of fully-qualified name:
+  In other words, select "UserDict.UserDict", hit some magic key and
+  it loads up UserDict.py and finds the first def or class for UserDict.
+- need a way to force colorization on/off
+- need a way to force auto-indent on/off
+
+Details:
+
+- ^O (on Unix -- open-line) should honor autoindent
+- after paste, show end of pasted text
+- on Windows, should turn short filename to long filename (not only in argv!)
+  (shouldn't this be done -- or undone -- by ntpath.normpath?)
+- new autoindent after colon even indents when the colon is in a comment!
+- sometimes forward slashes in pathname remain
+- sometimes star in window name remains in Windows menu
+- With unix bindings, ESC by itself is ignored
+- Sometimes for no apparent reason a selection from the cursor to the
+  end of the command buffer appears, which is hard to get rid of
+  because it stays when you are typing!
+- The Line/Col in the status bar can be wrong initially in PyShell DONE
+
+Structural problems:
+
+- too much knowledge in FileList about EditorWindow (for example)
+- should add some primitives for accessing the selection etc.
+  to repeat cumbersome code over and over
+
+======================================================================
+
+Jeff Bauer suggests:
+
+- Open Module doesn't appear to handle hierarchical packages.
+- Class browser should also allow hierarchical packages.
+- Open and Open Module could benefit from a history, DONE
+  either command line style, or Microsoft recent-file
+  style.
+- Add a Smalltalk-style inspector  (i.e. Tkinspect)
+
+The last suggestion is already a reality, but not yet
+integrated into IDLE.  I use a module called inspector.py,
+that used to be available from python.org(?)  It no longer
+appears to be in the contributed section, and the source
+has no author attribution.
+
+In any case, the code is useful for visually navigating
+an object's attributes, including its container hierarchy.
+
+    >>> from inspector import Tkinspect
+    >>> Tkinspect(None, myObject)
+
+Tkinspect could probably be extended and refined to
+integrate better into IDLE.
+
+======================================================================
+
+Comparison to PTUI
+------------------
+
++ PTUI's help is better (HTML!)
+
++ PTUI can attach a shell to any module
+
++ PTUI has some more I/O commands:
+  open multiple
+  append
+  examine (what's that?)
+
+======================================================================
+
+Notes after trying to run Grail
+-------------------------------
+
+- Grail does stuff to sys.path based on sys.argv[0]; you must set
+sys.argv[0] to something decent first (it is normally set to the path of
+the idle script).
+
+- Grail must be exec'ed in __main__ because that's imported by some
+other parts of Grail.
+
+- Grail uses a module called History and so does idle :-(
+
+======================================================================
+
+Robin Friedrich's items:
+
+Things I'd like to see:
+    - I'd like support for shift-click extending the selection. There's a
+      bug now that it doesn't work the first time you try it.
+    - Printing is needed. How hard can that be on Windows? FIRST CUT DONE
+    - The python-mode trick of autoindenting a line with <tab> is neat and
+      very handy.
+    - (someday) a spellchecker for docstrings and comments.
+    - a pagedown/up command key which moves to next class/def statement (top
+      level)
+    - split window capability
+    - DnD text relocation/copying
+
+Things I don't want to see.
+    - line numbers...  will probably slow things down way too much.
+    - Please use another icon for the tree browser leaf. The small snake
+      isn't cutting it.
+
+----------------------------------------------------------------------
+
+- Customizable views (multi-window or multi-pane).  (Markus Gritsch)
+
+- Being able to double click (maybe double right click) on a callable
+object in the editor which shows the source of the object, if
+possible.  (Gerrit Holl)
+
+- Hooks into the guts, like in Emacs.  (Mike Romberg)
+
+- Sharing the editor with a remote tutor.  (Martijn Faassen)
+
+- Multiple views on the same file.  (Tony J Ibbs)
+
+- Store breakpoints in a global (per-project) database (GvR); Dirk
+Heise adds: save some space-trimmed context and search around when
+reopening a file that might have been edited by someone else.
+
+- Capture menu events in extensions without changing the IDLE source.
+(Matthias Barmeier)
+
+- Use overlapping panels (a "notebook" in MFC terms I think) for info
+that doesn't need to be accessible simultaneously (e.g. HTML source
+and output).  Use multi-pane windows for info that does need to be
+shown together (e.g. class browser and source).  (Albert Brandl)
+
+- A project should invisibly track all symbols, for instant search,
+replace and cross-ref.  Projects should be allowed to span multiple
+directories, hosts, etc.  Project management files are placed in a
+directory you specify.  A global mapping between project names and
+project directories should exist [not so sure --GvR].  (Tim Peters)
+
+- Merge attr-tips and auto-expand.  (Mark Hammond, Tim Peters)
+
+- Python Shell should behave more like a "shell window" as users know
+it -- i.e. you can only edit the current command, and the cursor can't
+escape from the command area.  (Albert Brandl)
+
+- Set X11 class to "idle/Idle", set icon and title to something
+beginning with "idle" -- for window manangers.  (Randall Hopper)
+
+- Config files editable through a preferences dialog.  (me) DONE
+
+- Config files still editable outside the preferences dialog.
+(Randall Hopper) DONE
+
+- When you're editing a command in PyShell, and there are only blank
+lines below the cursor, hitting Return should ignore or delete those
+blank lines rather than deciding you're not on the last line.  (me)
+
+- Run command (F5 c.s.) should be more like Pythonwin's Run -- a
+dialog with options to give command line arguments, run the debugger,
+etc.  (me)
+
+- Shouldn't be able to delete part of the prompt (or any text before
+it) in the PyShell.  (Martijn Faassen)   DONE
+
+- Emacs style auto-fill (also smart about comments and strings).
+(Jeremy Hylton)
+
+- Output of Run Script should go to a separate output window, not to
+the shell window.  Output of separate runs should all go to the same
+window but clearly delimited.  (David Scherer) REJECT FIRST, LATTER DONE
+
+- GUI form designer to kick VB's butt.  (Robert Geiger) THAT'S NOT IDLE
+
+- Printing!  Possibly via generation of PDF files which the user must
+then send to the printer separately.  (Dinu Gherman)  FIRST CUT

+#     default configuration files in idlelib
+#     --------------------------------------
+#     config-main.def         default general config file
+#     config-extensions.def   default extension config file
+#     config-highlight.def    default highlighting config file
+#     config-keys.def         default keybinding config file
+#
+#     user configuration files in ~/.idlerc
+#     -------------------------------------
+#     config-main.cfg         user general config file
+#     config-extensions.cfg   user extension config file
+#     config-highlight.cfg    user highlighting config file
+#     config-keys.cfg         user keybinding config file
+#
+# On Windows, the default location of the home directory ('~' above)
+# depends on the version.  For Windows 10, it is C:\Users\<username>.
+#
+# Any options the user saves through the config dialog will be saved to
+# the relevant user config file. Reverting any general or extension
+# setting to the default causes that entry to be wiped from the user
+# file and re-read from the default file.  This rule applies to each
+# item, except that the three editor font items are saved as a group.
+#
+# User highlighting themes and keybinding sets must have (section) names
+# distinct from the default names.  All items are added and saved as a
+# group. They are retained unless specifically deleted within the config
+# dialog. Choosing one of the default themes or keysets just applies the
+# relevant settings from the default file.
+#
+# Additional help sources are listed in the [HelpFiles] section below
+# and should be viewable by a web browser (or the Windows Help viewer in
+# the case of .chm files). These sources will be listed on the Help
+# menu.  The pattern, and two examples, are:
+#
+# <sequence_number = menu item;/path/to/help/source>
+# 1 = IDLE;C:/Programs/Python36/Lib/idlelib/help.html
+# 2 = Pillow;https://pillow.readthedocs.io/en/latest/
+#
+# You can't use a semi-colon in a menu item or path.  The path will be
+# platform specific because of path separators, drive specs etc.
+#
+# The default files should not be edited except to add new sections to
+# config-extensions.def for added extensions.  The user files should be
+# modified through the Settings dialog.

+"""idlelib.config -- Manage IDLE configuration information.
+
+The comments at the beginning of config-main.def describe the
+configuration files and the design implemented to update user
+configuration information.  In particular, user configuration choices
+which duplicate the defaults will be removed from the user's
+configuration files, and if a user file becomes empty, it will be
+deleted.
+
+The configuration database maps options to values.  Conceptually, the
+database keys are tuples (config-type, section, item).  As implemented,
+there are  separate dicts for default and user values.  Each has
+config-type keys 'main', 'extensions', 'highlight', and 'keys'.  The
+value for each key is a ConfigParser instance that maps section and item
+to values.  For 'main' and 'extensions', user values override
+default values.  For 'highlight' and 'keys', user sections augment the
+default sections (and must, therefore, have distinct names).
+
+Throughout this module there is an emphasis on returning useable defaults
+when a problem occurs in returning a requested configuration value back to
+idle. This is to allow IDLE to continue to function in spite of errors in
+the retrieval of config information. When a default is returned instead of
+a requested config value, a message is printed to stderr to aid in
+configuration problem notification and resolution.

+
+        Enable users to provisionally change foreground and background
+        colors applied to textual tags.  Color mappings are stored in
+        complete listings called themes.  Built-in themes in
+        idlelib/config-highlight.def are fixed as far as the dialog is
+        concerned. Any theme can be used as the base for a new custom
+        theme, stored in .idlerc/config-highlight.cfg.
+
+        Function load_theme_cfg() initializes tk variables and theme
+        lists and calls paint_theme_sample() and set_highlight_target()
+        for the current theme.  Radiobuttons builtin_theme_on and
+        custom_theme_on toggle var theme_source, which controls if the
+        current set of colors are from a builtin or custom theme.
+        DynOptionMenus builtinlist and customlist contain lists of the
+        builtin and custom themes, respectively, and the current item
+        from each list is stored in vars builtin_name and custom_name.
+
+        Function paint_theme_sample() applies the colors from the theme
+        to the tags in text widget highlight_sample and then invokes
+        set_color_sample().  Function set_highlight_target() sets the state
+        of the radiobuttons fg_on and bg_on based on the tag and it also
+        invokes set_color_sample().
+
+        Function set_color_sample() sets the background color for the frame
+        holding the color selector.  This provides a larger visual of the
+        color for the current tag and plane (foreground/background).
+
+        Note: set_color_sample() is called from many places and is often
+        called more than once when a change is made.  It is invoked when
+        foreground or background is selected (radiobuttons), from
+        paint_theme_sample() (theme is changed or load_cfg is called), and
+        from set_highlight_target() (target tag is changed or load_cfg called).
+
+        Button delete_custom invokes delete_custom() to delete
+        a custom theme from idleConf.userCfg['highlight'] and changes.
+        Button save_custom invokes save_as_new_theme() which calls
+        get_new_theme_name() and create_new() to save a custom theme
+        and its colors to idleConf.userCfg['highlight'].
+
+        Radiobuttons fg_on and bg_on toggle var fg_bg_toggle to control
+        if the current selected color for a tag is for the foreground or
+        background.
+
+        DynOptionMenu targetlist contains a readable description of the
+        tags applied to Python source within IDLE.  Selecting one of the
+        tags from this list populates highlight_target, which has a callback
+        function set_highlight_target().
+
+        Text widget highlight_sample displays a block of text (which is
+        mock Python code) in which is embedded the defined tags and reflects
+        the color attributes of the current theme and changes for those tags.
+        Mouse button 1 allows for selection of a tag and updates
+        highlight_target with that tag value.
+
+        Note: The font in highlight_sample is set through the config in
+        the fonts tab.
+
+        In other words, a tag can be selected either from targetlist or
+        by clicking on the sample text within highlight_sample.  The
+        plane (foreground/background) is selected via the radiobutton.
+        Together, these two (tag and plane) control what color is
+        shown in set_color_sample() for the current theme.  Button set_color
+        invokes get_color() which displays a ColorChooser to change the
+        color for the selected tag/plane.  If a new color is picked,
+        it will be saved to changes and the highlight_sample and
+        frame background will be updated.

+
+        Enable users to provisionally change both individual and sets of
+        keybindings (shortcut keys). Except for features implemented as
+        extensions, keybindings are stored in complete sets called
+        keysets. Built-in keysets in idlelib/config-keys.def are fixed
+        as far as the dialog is concerned. Any keyset can be used as the
+        base for a new custom keyset, stored in .idlerc/config-keys.cfg.
+
+        Function load_key_cfg() initializes tk variables and keyset
+        lists and calls load_keys_list for the current keyset.
+        Radiobuttons builtin_keyset_on and custom_keyset_on toggle var
+        keyset_source, which controls if the current set of keybindings
+        are from a builtin or custom keyset. DynOptionMenus builtinlist
+        and customlist contain lists of the builtin and custom keysets,
+        respectively, and the current item from each list is stored in
+        vars builtin_name and custom_name.
+
+        Button delete_custom_keys invokes delete_custom_keys() to delete
+        a custom keyset from idleConf.userCfg['keys'] and changes.  Button
+        save_custom_keys invokes save_as_new_key_set() which calls
+        get_new_keys_name() and create_new_key_set() to save a custom keyset
+        and its keybindings to idleConf.userCfg['keys'].
+
+        Listbox bindingslist contains all of the keybindings for the
+        selected keyset.  The keybindings are loaded in load_keys_list()
+        and are pairs of (event, [keys]) where keys can be a list
+        of one or more key combinations to bind to the same event.
+        Mouse button 1 click invokes on_bindingslist_select(), which
+        allows button_new_keys to be clicked.
+
+        So, an item is selected in listbindings, which activates
+        button_new_keys, and clicking button_new_keys calls function
+        get_new_keys().  Function get_new_keys() gets the key mappings from the
+        current keyset for the binding event item that was selected.  The
+        function then displays another dialog, GetKeysDialog, with the
+        selected binding event and current keys and allows new key sequences
+        to be entered for that binding event.  If the keys aren't
+        changed, nothing happens.  If the keys are changed and the keyset
+        is a builtin, function get_new_keys_name() will be called
+        for input of a custom keyset name.  If no name is given, then the
+        change to the keybinding will abort and no updates will be made.  If
+        a custom name is entered in the prompt or if the current keyset was
+        already custom (and thus didn't require a prompt), then
+        idleConf.userCfg['keys'] is updated in function create_new_key_set()
+        with the change to the event binding.  The item listing in bindingslist
+        is updated with the new keys.  Var keybinding is also set which invokes
+        the callback function, var_changed_keybinding, to add the change to
+        the 'keys' or 'extensions' changes tracker based on the binding type.

+Writing an IDLE extension
+=========================
+
+An IDLE extension can define new key bindings and menu entries for IDLE
+edit windows.  There is a simple mechanism to load extensions when IDLE
+starts up and to attach them to each edit window. (It is also possible
+to make other changes to IDLE, but this must be done by editing the IDLE
+source code.)
+
+The list of extensions loaded at startup time is configured by editing
+the file config-extensions.def.  See below for details.
+
+An IDLE extension is defined by a class.  Methods of the class define
+actions that are invoked by event bindings or menu entries. Class (or
+instance) variables define the bindings and menu additions; these are
+automatically applied by IDLE when the extension is linked to an edit
+window.
+
+An IDLE extension class is instantiated with a single argument,
+`editwin', an EditorWindow instance. The extension cannot assume much
+about this argument, but it is guaranteed to have the following instance
+variables:
+
+    text	a Text instance (a widget)
+    io		an IOBinding instance (more about this later)
+    flist	the FileList instance (shared by all edit windows)
+
+(There are a few more, but they are rarely useful.)
+
+The extension class must not directly bind Window Manager (e.g. X) events.
+Rather, it must define one or more virtual events, e.g. <<z-in>>, and
+corresponding methods, e.g. z_in_event().  The virtual events will be
+bound to the corresponding methods, and Window Manager events can then be bound
+to the virtual events. (This indirection is done so that the key bindings can
+easily be changed, and so that other sources of virtual events can exist, such
+as menu entries.)
+
+An extension can define menu entries.  This is done with a class or instance
+variable named menudefs; it should be a list of pairs, where each pair is a
+menu name (lowercase) and a list of menu entries. Each menu entry is either
+None (to insert a separator entry) or a pair of strings (menu_label,
+virtual_event).  Here, menu_label is the label of the menu entry, and
+virtual_event is the virtual event to be generated when the entry is selected.
+An underscore in the menu label is removed; the character following the
+underscore is displayed underlined, to indicate the shortcut character (for
+Windows).
+
+At the moment, extensions cannot define whole new menus; they must define
+entries in existing menus.  Some menus are not present on some windows; such
+entry definitions are then ignored, but key bindings are still applied.  (This
+should probably be refined in the future.)
+
+Extensions are not required to define menu entries for all the events they
+implement.  (They are also not required to create keybindings, but in that
+case there must be empty bindings in cofig-extensions.def)
+
+Here is a partial example from zzdummy.py:
+
+class ZzDummy:
+
+    menudefs = [
+        ('format', [
+            ('Z in', '<<z-in>>'),
+            ('Z out', '<<z-out>>'),
+        ] )
+    ]
+
+    def __init__(self, editwin):
+        self.editwin = editwin
+
+    def z_in_event(self, event=None):
+        "...Do what you want here..."
+
+The final piece of the puzzle is the file "config-extensions.def", which is
+used to configure the loading of extensions and to establish key (or, more
+generally, event) bindings to the virtual events defined in the extensions.
+

+Linux, each has its own top menu.  Each menu documented below indicates
+which window type it is associated with.</p>
+<p>Output windows, such as used for Edit =&gt; Find in Files, are a subtype of editor
+window.  They currently have the same top menu but a different
+default title and context menu.</p>
+<p>On macOS, there is one application menu.  It dynamically changes according
+to the window currently selected.  It has an IDLE menu, and some entries
+described below are moved around to conform to Apple guidelines.</p>

+<div class="section" id="completions">
+<span id="id3"></span><h3>Completions<a class="headerlink" href="#completions" title="Permalink to this headline">¶</a></h3>
+<p>Completions are supplied, when requested and available, for module
+names, attributes of classes or functions, or filenames.  Each request
+method displays a completion box with existing names.  (See tab
+completions below for an exception.) For any box, change the name
+being completed and the item highlighted in the box by
+typing and deleting characters; by hitting <kbd class="kbd docutils literal notranslate">Up</kbd>, <kbd class="kbd docutils literal notranslate">Down</kbd>,
+<kbd class="kbd docutils literal notranslate">PageUp</kbd>, <kbd class="kbd docutils literal notranslate">PageDown</kbd>, <kbd class="kbd docutils literal notranslate">Home</kbd>, and <kbd class="kbd docutils literal notranslate">End</kbd> keys;
+and by a single click within the box.  Close the box with <kbd class="kbd docutils literal notranslate">Escape</kbd>,
+<kbd class="kbd docutils literal notranslate">Enter</kbd>, and double <kbd class="kbd docutils literal notranslate">Tab</kbd> keys or clicks outside the box.
+A double click within the box selects and closes.</p>
+<p>One way to open a box is to type a key character and wait for a
+predefined interval.  This defaults to 2 seconds; customize it
+in the settings dialog.  (To prevent auto popups, set the delay to a
+large number of milliseconds, such as 100000000.) For imported module
+names or class or function attributes, type ‘.’.
+For filenames in the root directory, type <a class="reference internal" href="os.html#os.sep" title="os.sep"><code class="xref py py-data docutils literal notranslate"><span class="pre">os.sep</span></code></a> or
+<a class="reference internal" href="os.html#os.altsep" title="os.altsep"><code class="xref py py-data docutils literal notranslate"><span class="pre">os.altsep</span></code></a> immediately after an opening quote.  (On Windows,
+one can specify a drive first.)  Move into subdirectories by typing a
+directory name and a separator.</p>
+<p>Instead of waiting, or after a box is closed, open a completion box
+immediately with Show Completions on the Edit menu.  The default hot
+key is <kbd class="kbd docutils literal notranslate"><kbd class="kbd docutils literal notranslate">C</kbd>-<kbd class="kbd docutils literal notranslate">space</kbd></kbd>.  If one types a prefix for the desired name
+before opening the box, the first match or near miss is made visible.
+The result is the same as if one enters a prefix
+after the box is displayed.  Show Completions after a quote completes
+filenames in the current directory instead of a root directory.</p>
+<p>Hitting <kbd class="kbd docutils literal notranslate">Tab</kbd> after a prefix usually has the same effect as Show
+Completions.  (With no prefix, it indents.)  However, if there is only
+one match to the prefix, that match is immediately added to the editor
+text without opening a box.</p>
+<p>Invoking ‘Show Completions’, or hitting <kbd class="kbd docutils literal notranslate">Tab</kbd> after a prefix,
+outside of a string and without a preceding ‘.’ opens a box with
+keywords, builtin names, and available module-level names.</p>
+<p>When editing code in an editor (as oppose to Shell), increase the
+available module-level names by running your code
+and not restarting the Shell thereafter.  This is especially useful
+after adding imports at the top of a file.  This also increases
+possible attribute completions.</p>
+<p>Completion boxes intially exclude names beginning with ‘_’ or, for
+modules, not included in ‘__all__’.  The hidden names can be accessed
+by typing ‘_’ after ‘.’, either before or after the box is opened.</p>

+<div class="section" id="calltips">
+<span id="id4"></span><h3>Calltips<a class="headerlink" href="#calltips" title="Permalink to this headline">¶</a></h3>
+<p>A calltip is shown automatically when one types <kbd class="kbd docutils literal notranslate">(</kbd> after the name

+dots and subscripts.  A calltip remains until it is clicked, the cursor

+Call Tip” on the menu or enter its shortcut to display a calltip.</p>
+<p>The calltip consists of the function’s signature and docstring up to

+<p>In Shell, the accessible functions depends on what modules have been
+imported into the user process, including those imported by Idle itself,
+and which definitions have been run, all since the last restart.</p>
+<p>For example, restart the Shell and enter <code class="docutils literal notranslate"><span class="pre">itertools.count(</span></code>.  A calltip
+appears because Idle imports itertools into the user process for its own
+use.  (This could change.)  Enter <code class="docutils literal notranslate"><span class="pre">turtle.write(</span></code> and nothing appears.
+Idle does not itself import turtle.  The menu entry and shortcut also do
+nothing.  Enter <code class="docutils literal notranslate"><span class="pre">import</span> <span class="pre">turtle</span></code>.  Thereafter, <code class="docutils literal notranslate"><span class="pre">turtle.write(</span></code>
+will display a calltip.</p>
+<p>In an editor, import statements have no effect until one runs the file.
+One might want to run a file after writing import statements, after
+adding function definitions, or after opening an existing file.</p>

+<h3>Startup failure<a class="headerlink" href="#startup-failure" title="Permalink to this headline">¶</a></h3>
+<p>IDLE uses a socket to communicate between the IDLE GUI process and the user
+code execution process.  A connection must be established whenever the Shell
+starts or restarts.  (The latter is indicated by a divider line that says
+‘RESTART’). If the user process fails to connect to the GUI process, it
+usually displays a <code class="docutils literal notranslate"><span class="pre">Tk</span></code> error box with a ‘cannot connect’ message
+that directs the user here.  It then exits.</p>
+<p>One specific connection failure on Unix systems results from
+misconfigured masquerading rules somewhere in a system’s network setup.
+When IDLE is started from a terminal, one will see a message starting
+with <code class="docutils literal notranslate"><span class="pre">**</span> <span class="pre">Invalid</span> <span class="pre">host:</span></code>.
+The valid value is <code class="docutils literal notranslate"><span class="pre">127.0.0.1</span> <span class="pre">(idlelib.rpc.LOCALHOST)</span></code>.
+One can diagnose with <code class="docutils literal notranslate"><span class="pre">tcpconnect</span> <span class="pre">-irv</span> <span class="pre">127.0.0.1</span> <span class="pre">6543</span></code> in one
+terminal window and <code class="docutils literal notranslate"><span class="pre">tcplisten</span> <span class="pre">&lt;same</span> <span class="pre">args&gt;</span></code> in another.</p>
+<p>A common cause of failure is a user-written file with the same name as a
+standard library module, such as <em>random.py</em> and <em>tkinter.py</em>. When such a
+file is located in the same directory as a file that is about to be run,
+IDLE cannot import the stdlib file.  The current fix is to rename the
+user file.</p>
+<p>Though less common than in the past, an antivirus or firewall program may
+stop the connection.  If the program cannot be taught to allow the
+connection, then it must be turned off for IDLE to work.  It is safe to
+allow this internal connection because no data is visible on external
+ports.  A similar problem is a network mis-configuration that blocks
+connections.</p>
+<p>Python installation issues occasionally stop IDLE: multiple versions can
+clash, or a single installation might need admin access.  If one undo the
+clash, or cannot or does not want to run as admin, it might be easiest to
+completely remove Python and start over.</p>
+<p>A zombie pythonw.exe process could be a problem.  On Windows, use Task
+Manager to check for one and stop it if there is.  Sometimes a restart
+initiated by a program crash or Keyboard Interrupt (control-C) may fail
+to connect.  Dismissing the error box or using Restart Shell on the Shell
+menu may fix a temporary problem.</p>
+<p>When IDLE first starts, it attempts to read user configuration files in
+<code class="docutils literal notranslate"><span class="pre">~/.idlerc/</span></code> (~ is one’s home directory).  If there is a problem, an error
+message should be displayed.  Leaving aside random disk glitches, this can
+be prevented by never editing the files by hand.  Instead, use the
+configuration dialog, under Options.  Once there is an error in a user
+configuration file, the best solution may be to delete it and start over
+with the settings dialog.</p>
+<p>If IDLE quits with no message, and it was not started from a console, try
+starting it from a console or terminal (<code class="docutils literal notranslate"><span class="pre">python</span> <span class="pre">-m</span> <span class="pre">idlelib</span></code>) and see if
+this results in an error message.</p>
+<p>On Unix-based systems with tcl/tk older than <code class="docutils literal notranslate"><span class="pre">8.6.11</span></code> (see
+<code class="docutils literal notranslate"><span class="pre">About</span> <span class="pre">IDLE</span></code>) certain characters of certain fonts can cause
+a tk failure with a message to the terminal.  This can happen either
+if one starts IDLE to edit a file with such a character or later
+when entering such a character.  If one cannot upgrade tcl/tk,
+then re-configure IDLE to use a font that works better.</p>

+<div class="section" id="running-user-code">
+<h3>Running user code<a class="headerlink" href="#running-user-code" title="Permalink to this headline">¶</a></h3>
+<p>With rare exceptions, the result of executing Python code with IDLE is
+intended to be the same as executing the same code by the default method,
+directly with Python in a text-mode system console or terminal window.
+However, the different interface and operation occasionally affect
+visible results.  For instance, <code class="docutils literal notranslate"><span class="pre">sys.modules</span></code> starts with more entries,
+and <code class="docutils literal notranslate"><span class="pre">threading.activeCount()</span></code> returns 2 instead of 1.</p>
+<p>By default, IDLE runs user code in a separate OS process rather than in
+the user interface process that runs the shell and editor.  In the execution
+process, it replaces <code class="docutils literal notranslate"><span class="pre">sys.stdin</span></code>, <code class="docutils literal notranslate"><span class="pre">sys.stdout</span></code>, and <code class="docutils literal notranslate"><span class="pre">sys.stderr</span></code>
+with objects that get input from and send output to the Shell window.
+The original values stored in <code class="docutils literal notranslate"><span class="pre">sys.__stdin__</span></code>, <code class="docutils literal notranslate"><span class="pre">sys.__stdout__</span></code>, and
+<code class="docutils literal notranslate"><span class="pre">sys.__stderr__</span></code> are not touched, but may be <code class="docutils literal notranslate"><span class="pre">None</span></code>.</p>
+<p>Sending print output from one process to a text widget in another is
+slower than printing to a system terminal in the same process.
+This has the most effect when printing multiple arguments, as the string
+for each argument, each separator, the newline are sent separately.
+For development, this is usually not a problem, but if one wants to
+print faster in IDLE, format and join together everything one wants
+displayed together and then print a single string.  Both format strings
+and <a class="reference internal" href="stdtypes.html#str.join" title="str.join"><code class="xref py py-meth docutils literal notranslate"><span class="pre">str.join()</span></code></a> can help combine fields and lines.</p>
+<p>IDLE’s standard stream replacements are not inherited by subprocesses
+created in the execution process, whether directly by user code or by
+modules such as multiprocessing.  If such subprocess use <code class="docutils literal notranslate"><span class="pre">input</span></code> from
+sys.stdin or <code class="docutils literal notranslate"><span class="pre">print</span></code> or <code class="docutils literal notranslate"><span class="pre">write</span></code> to sys.stdout or sys.stderr,
+IDLE should be started in a command line window.  The secondary subprocess
+will then be attached to that window for input and output.</p>
+<p>If <code class="docutils literal notranslate"><span class="pre">sys</span></code> is reset by user code, such as with <code class="docutils literal notranslate"><span class="pre">importlib.reload(sys)</span></code>,
+IDLE’s changes are lost and input from the keyboard and output to the screen
+will not work correctly.</p>
+<p>When Shell has the focus, it controls the keyboard and screen.  This is
+normally transparent, but functions that directly access the keyboard
+and screen will not work.  These include system-specific functions that
+determine whether a key has been pressed and if so, which.</p>
+<p>The IDLE code running in the execution process adds frames to the call stack
+that would not be there otherwise.  IDLE wraps <code class="docutils literal notranslate"><span class="pre">sys.getrecursionlimit</span></code> and
+<code class="docutils literal notranslate"><span class="pre">sys.setrecursionlimit</span></code> to reduce the effect of the additional stack
+frames.</p>
+<p>When user code raises SystemExit either directly or by calling sys.exit,
+IDLE returns to a Shell prompt instead of exiting.</p>
+</div>
+<div class="section" id="user-output-in-shell">
+<h3>User output in Shell<a class="headerlink" href="#user-output-in-shell" title="Permalink to this headline">¶</a></h3>
+<p>When a program outputs text, the result is determined by the
+corresponding output device.  When IDLE executes user code, <code class="docutils literal notranslate"><span class="pre">sys.stdout</span></code>
+and <code class="docutils literal notranslate"><span class="pre">sys.stderr</span></code> are connected to the display area of IDLE’s Shell.  Some of
+its features are inherited from the underlying Tk Text widget.  Others
+are programmed additions.  Where it matters, Shell is designed for development
+rather than production runs.</p>
+<p>For instance, Shell never throws away output.  A program that sends unlimited
+output to Shell will eventually fill memory, resulting in a memory error.
+In contrast, some system text windows only keep the last n lines of output.
+A Windows console, for instance, keeps a user-settable 1 to 9999 lines,
+with 300 the default.</p>
+<p>A Tk Text widget, and hence IDLE’s Shell, displays characters (codepoints) in
+the BMP (Basic Multilingual Plane) subset of Unicode.  Which characters are
+displayed with a proper glyph and which with a replacement box depends on the
+operating system and installed fonts.  Tab characters cause the following text
+to begin after the next tab stop. (They occur every 8 ‘characters’).  Newline
+characters cause following text to appear on a new line.  Other control
+characters are ignored or displayed as a space, box, or something else,
+depending on the operating system and font.  (Moving the text cursor through
+such output with arrow keys may exhibit some surprising spacing behavior.)</p>

+<p>The <code class="docutils literal notranslate"><span class="pre">repr</span></code> function is used for interactive echo of expression
+values.  It returns an altered version of the input string in which
+control codes, some BMP codepoints, and all non-BMP codepoints are
+replaced with escape codes. As demonstrated above, it allows one to
+identify the characters in a string, regardless of how they are displayed.</p>
+<p>Normal and error output are generally kept separate (on separate lines)
+from code input and each other.  They each get different highlight colors.</p>
+<p>For SyntaxError tracebacks, the normal ‘^’ marking where the error was
+detected is replaced by coloring the text with an error highlight.
+When code run from a file causes other exceptions, one may right click
+on a traceback line to jump to the corresponding line in an IDLE editor.
+The file will be opened if necessary.</p>
+<p>Shell has a special facility for squeezing output lines down to a
+‘Squeezed text’ label.  This is done automatically
+for output over N lines (N = 50 by default).
+N can be changed in the PyShell section of the General
+page of the Settings dialog.  Output with fewer lines can be squeezed by
+right clicking on the output.  This can be useful lines long enough to slow

+<h3>Developing tkinter applications<a class="headerlink" href="#developing-tkinter-applications" title="Permalink to this headline">¶</a></h3>
+<p>IDLE is intentionally different from standard Python in order to

+in IDLE and a tk window appears.  In standard Python, one must also enter
+<code class="docutils literal notranslate"><span class="pre">root.update()</span></code> to see the window.  IDLE does the equivalent in the
+background, about 20 times a second, which is about every 50 milliseconds.
+Next enter <code class="docutils literal notranslate"><span class="pre">b</span> <span class="pre">=</span> <span class="pre">tk.Button(root,</span> <span class="pre">text='button');</span> <span class="pre">b.pack()</span></code>.  Again,

+<p>Most tkinter programs run <code class="docutils literal notranslate"><span class="pre">root.mainloop()</span></code>, which usually does not

+<p>When running a tkinter program from an IDLE editor, one can comment out

+<div class="section" id="running-without-a-subprocess">
+<h3>Running without a subprocess<a class="headerlink" href="#running-without-a-subprocess" title="Permalink to this headline">¶</a></h3>
+<p>By default, IDLE executes user code in a separate subprocess via a socket,
+which uses the internal loopback interface.  This connection is not
+externally visible and no data is sent to or received from the Internet.
+If firewall software complains anyway, you can ignore it.</p>
+<p>If the attempt to make the socket connection fails, Idle will notify you.
+Such failures are sometimes transient, but if persistent, the problem
+may be either a firewall blocking the connection or misconfiguration of
+a particular system.  Until the problem is fixed, one can run Idle with
+the -n command line switch.</p>
+<p>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

+other characters of personal interest.  Use the sample to select
+monospaced fonts.  If particular characters have problems in Shell or an
+editor, add them to the top of the sample and try changing first size
+and then font.</p>
+<p>On the Highlights and Keys tab, select a built-in or custom color theme
+and key set.  To use a newer built-in color theme or key set with older
+IDLEs, save it as a new custom theme or key set and it well be accessible
+to older IDLEs.</p>

+"""
+MultiCall - a class which inherits its methods from a Tkinter widget (Text, for
+example), but enables multiple calls of functions per virtual event - all
+matching events will be called, not only the most specific one. This is done
+by wrapping the event functions - event_add, event_delete and event_info.
+MultiCall recognizes only a subset of legal event sequences. Sequences which
+are not recognized are treated by the original Tk handling mechanism. A
+more-specific event will be called before a less-specific event.
+
+The recognized sequences are complete one-event sequences (no emacs-style
+Ctrl-X Ctrl-C, no shortcuts like <3>), for all types of events.
+Key/Button Press/Release events can have modifiers.
+The recognized modifiers are Shift, Control, Option and Command for Mac, and
+Control, Alt, Shift, Meta/M for other platforms.
+
+For all events which were handled by MultiCall, a new member is added to the
+event instance passed to the binded functions - mc_type. This is one of the
+event type constants defined in this module (such as MC_KEYPRESS).
+For Key/Button events (which are handled by MultiCall and may receive
+modifiers), another member is added - mc_state. This member gives the state
+of the recognized modifiers, as a combination of the modifier constants
+also defined in this module (for example, MC_SHIFT).
+Using these members is absolutely portable.
+
+The order by which events are called is defined by these rules:
+1. A more-specific event will be called before a less-specific event.
+2. A recently-binded event will be called before a previously-binded event,
+   unless this conflicts with the first rule.
+Each function will be called at most once for each event.

+       idle  [-dns] [-t title] (-c cmd | -r file) [arg]*
+       idle  [-dns] [-t title] - [arg]*
+
+  -h         print this help message and exit
+  -n         run IDLE without a subprocess (DEPRECATED,
+             see Help/IDLE Help for details)
+
+The following options will override the IDLE 'settings' configuration:
+
+  -e         open an edit window
+  -i         open a shell window
+
+The following options imply -i and will open a shell:
+
+  -c cmd     run the command in a shell, or
+  -r file    run script from file
+
+  -d         enable the debugger
+  -s         run $IDLESTARTUP or $PYTHONSTARTUP before anything else
+  -t title   set title of shell window
+
+A default edit window will be bypassed when -c, -r, or - are used.
+
+[arg]* are passed to the command (-c) or script (-r) in sys.argv[1:].
+
+Examples:
+
+idle
+        Open an edit window or shell depending on IDLE's configuration.
+
+idle foo.py foobar.py
+        Edit the files, also open a shell if configured to start with shell.
+
+idle -est "Baz" foo.py
+        Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell
+        window with the title "Baz".
+
+idle -c "import sys; print(sys.argv)" "foo"
+        Open a shell window and run the command, passing "-c" in sys.argv[0]
+        and "foo" in sys.argv[1].
+
+idle -d -s -r foo.py "Hello World"
+        Open a shell window, run a startup script, enable the debugger, and
+        run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
+        sys.argv[1].
+
+echo "import sys; print(sys.argv)" | idle - "foobar"
+        Open a shell window, run the script piped in, passing '' in sys.argv[0]
+        and "foobar" in sys.argv[1].

+"""An IDLE extension to avoid having very long texts printed in the shell.
+
+A common problem in IDLE's interactive shell is printing of large amounts of
+text into the shell. This makes looking at the previous history difficult.
+Worse, this can cause IDLE to become very slow, even to the point of being
+completely unusable.
+
+This extension will automatically replace long texts with a small button.
+Double-clicking this button will remove it and insert the original text instead.
+Middle-clicking will copy the text to the clipboard. Right-clicking will open
+the text in a separate viewing window.
+
+Additionally, any output can be manually "squeezed" by the user. This includes
+output written to the standard error stream ("stderr"), such as exception
+messages and their tracebacks.

+

+    Do basic configuration for the logging system.
+
+    This function does nothing if the root logger already has handlers
+    configured, unless the keyword argument *force* is set to ``True``.
+    It is a convenience method intended for use by simple scripts
+    to do one-shot configuration of the logging package.
+
+    The default behaviour is to create a StreamHandler which writes to
+    sys.stderr, set a formatter using the BASIC_FORMAT format string, and
+    add the handler to the root logger.
+
+    A number of optional keyword arguments may be specified, which can alter
+    the default behaviour.
+
+    filename  Specifies that a FileHandler be created, using the specified
+              filename, rather than a StreamHandler.
+    filemode  Specifies the mode to open the file, if filename is specified
+              (if filemode is unspecified, it defaults to 'a').
+    format    Use the specified format string for the handler.
+    datefmt   Use the specified date/time format.
+    style     If a format string is specified, use this to specify the
+              type of format string (possible values '%', '{', '$', for
+              %-formatting, :meth:`str.format` and :class:`string.Template`
+              - defaults to '%').
+    level     Set the root logger level to the specified level.
+    stream    Use the specified stream to initialize the StreamHandler. Note
+              that this argument is incompatible with 'filename' - if both
+              are present, 'stream' is ignored.
+    handlers  If specified, this should be an iterable of already created
+              handlers, which will be added to the root handler. Any handler
+              in the list which does not have a formatter assigned will be
+              assigned the formatter created in this function.
+    force     If this keyword  is specified as true, any existing handlers
+              attached to the root logger are removed and closed, before
+              carrying out the configuration as specified by the other
+              arguments.
+    Note that you could specify a stream created using open(filename, mode)
+    rather than passing the filename and mode in. However, it should be
+    remembered that StreamHandler does not close its stream (since it may be
+    using sys.stdout or sys.stderr), whereas FileHandler closes its stream
+    when the handler is closed.

+# On Unix we run a server process which keeps track of unlinked

+# end of the pipe, so we get EOF when all other processes have exited.
+# Then the server process unlinks any remaining resource names.
+#
+# This is important because there may be system limits for such resources: for
+# instance, the system only supports a limited number of named semaphores, and
+# shared-memory segments live in the RAM. If a python process leaks such a
+# resource, this resource will not be removed till the next reboot.  Without
+# this resource tracker process, "killall python" would probably leave unlinked

+
+parsers -- Python wrappers for XML parsers (currently only supports Expat).
+
+sax -- The Simple API for XML, developed by XML-Dev, led by David
+       Megginson and ported to Python by Lars Marius Garshol.  This
+       supports the SAX 2 API.
