SEARCHING for CONFIG symbols



Searching in menuconfig:



	The Search function searches for kernel configuration symbol

	names, so you have to know something close to what you are

	looking for.



	Example:

		/hotplug

		This lists all config symbols that contain "hotplug",

		e.g., HOTPLUG, HOTPLUG_CPU, MEMORY_HOTPLUG.



	For search help, enter / followed TAB-TAB-TAB (to highlight

	<Help>) and Enter.  This will tell you that you can also use

	regular expressions (regexes) in the search string, so if you

	are not interested in MEMORY_HOTPLUG, you could try



		/^hotplug

Color Themes for 'menuconfig'

Environment variables for '*config'



It is possible to select different color themes using the variable

MENUCONFIG_COLOR.  To select a theme use:

This environment variable can be used to specify a default kernel config

file name to override the default name of ".config".

If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not

break symlinks when .config is a symlink to somewhere else.



Available themes are:

  mono       => selects colors suitable for monochrome displays

  blackbg    => selects a color scheme with black background

  classic    => theme with blue background. The classic look

  bluetitle  => a LCD friendly version of classic. (default)

If this environment variable exists and is non-null, the timestamp line

in generated .config files is omitted.
