# IDLE reads several config files to determine user preferences.  This 
# file is the default config file for general idle settings.
#  
# When IDLE starts, it will look in
# the following two sets of files, in order:
#
#     default configuration
#     ---------------------
#     config-main.def         the default general config file
#     config-extensions.def   the default extension config file
#     config-highlight.def    the default highlighting config file
#     config-keys.def         the default keybinding config file
#
#     user configuration
#     -------------------
#     ~/.idlerc/idle-main.cfg            the user general config file
#     ~/.idlerc/idle-extensions.cfg      the user extension config file
#     ~/.idlerc/idle-highlight.cfg       the user highlighting config file
#     ~/.idlerc/idle-keys.cfg            the user keybinding config file
#
# Any options the user saves through the config dialog will be saved to
# the relevant user config file. Reverting any general setting to the 
# default causes that entry to be wiped from the user file and re-read 
# from the default file. User highlighting themes or keybinding sets 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 and must 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 is 
# <sequence_number = menu item;/path/to/help/source> 
# 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.
#
# It is best to use the Configuration GUI to set up additional help sources!
# Example:
#1 = My Extra Help Source;/usr/share/doc/foo/index.html
#2 = Another Help Source;/path/to/another.pdf
