+# IDLE reads several config files to determine user preferences. This
+# file is the default config file. When IDLE starts, it will look in
+# the following four files in order:
+# config.txt the default config file
+# config-[win/unix/mac].txt the generic platform config file
+# config-[sys.platform].txt the specific platform config file
+# ~/.idle the user config file
+# XXX what about Windows?
+#
+# The last definition of each option is used. For example, you can
+# override the default window size (80x24) by defining width and
+# height options in the EditorWindow section of your ~/.idle file
+#
+# IDLE extensions can be enabled and disabled by adding them to one of
+# the config files. To enable an extension, create a section with the
+# same name as the extension, e.g. the [ParenMatch] section below. To
+# disable an extension, either remove the section or add the the
+# enable option with the value 0.
