NAME

       kconfig-monf - Standalone implementation of the Linux Kconfig parser

SYNOPSIS

       kconfig-mconf [options] <KConfig_file>

DESCRIPTION

       The kconfig toolkit support the Kconfig language and implement the parser and the
       configuration support associated to the KConfig files respecting the Linux kernel KConfig
       convention.

       At configuration time:

       • kconfig-mconf is based on ncurses (menuconfig)

       • kconfig-conf is based on dialog (config)

       • kconfig-gconf is based on GTK+ (gconfig)

       Associated tools:

       • kconfig-diff displays symbols diff between .config files

OPTIONS

       --silentoldconfig Only for kconfig-conf, reload a given .config and regenerate header and
       command files accordingly.

       --allnoconfig Set all boolean configuration to no.

       --allyesconfig Set all boolean configuration to yes.

       --randconfig Generates a random configuration.

ENVIRONMENT

Environment variables for '*config'

       KCONFIG_CONFIG

       This environment variable can be used to specify a default kernel config file name to
       override the default name of ".config".

       KCONFIG_OVERWRITECONFIG

       If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not break symlinks
       when .config is a symlink to somewhere else.

       CONFIG_

       If you set CONFIG_ in the environment, Kconfig will prefix all symbols with its value when
       saving the configuration, instead of using the default, "CONFIG_".

Environment variables for '{allyes/allmod/allno/rand}config'

       KCONFIG_ALLCONFIG

       The allyesconfig/allmodconfig/allnoconfig/randconfig variants can also use the environment
       variable KCONFIG_ALLCONFIG as a flag or a filename that contains config symbols that the
       user requires to be set to a specific value.  If KCONFIG_ALLCONFIG is used without a
       filename where KCONFIG_ALLCONFIG == "" or KCONFIG_ALLCONFIG == "1", "make *config" checks
       for a file named "all{yes/mod/no/def/random}.config" (corresponding to the *config command
       that was used) for symbol values that are to be forced.  If this file is not found, it
       checks for a file named "all.config" to contain forced values.

       This enables you to create "miniature" config (miniconfig) or custom config files
       containing just the config symbols that you are interested in.  Then the kernel config
       system generates the full .config file, including symbols of your miniconfig file.

       This 'KCONFIG_ALLCONFIG' file is a config file which contains (usually a subset of all)
       preset config symbols.  These variable settings are still subject to normal dependency
       checks.

       Examples:
           KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig or
           KCONFIG_ALLCONFIG=mini.config make allnoconfig or
           make KCONFIG_ALLCONFIG=mini.config allnoconfig

       These examples will disable most options (allnoconfig) but enable or disable the options
       that are explicitly listed in the specified mini-config files.

Environment variables for 'randconfig'

       KCONFIG_SEED

       You can set this to the integer value used to seed the RNG, if you want to somehow debug
       the behaviour of the kconfig parser/frontends.  If not set, the current time will be used.

       KCONFIG_PROBABILITY

       This variable can be used to skew the probabilities.  See
       /usr/share/doc/kconfig-frontends/kconfig.txt.gz.

       Environment variables for 'silentoldconfig'

       KCONFIG_NOSILENTUPDATE

       If this variable has a non-blank value, it prevents silent kernel config updates (requires
       explicit updates).

       KCONFIG_AUTOCONFIG

       This environment variable can be set to specify the path  name of the "auto.conf" file.
       Its default value is "include/config/auto.conf".

       KCONFIG_TRISTATE

       This environment variable can be set to specify the path  name of the "tristate.conf"
       file.  Its default value is "include/config/tristate.conf".

       KCONFIG_AUTOHEADER

       This environment variable can be set to specify the path  name of the "autoconf.h"
       (header) file.  Its default value is "include/generated/autoconf.h".
