"""IDLE Configuration Dialog: support user customization of IDLE by GUI
Customize font faces, sizes, and colorization attributes. Set indentation
defaults. Customize keybindings. Colorization and keybindings can be
saved as user defined sets. Select startup options including shell/editor
and default window size. Define additional help sources.
Note that tab width in IDLE is currently fixed at eight due to Tk issues.
Refer to comments in EditorWindow autoindent code for details.
