Manipulate options in a .config file from the command line.
|
|
Usage:
|
|
config options command ...
|
|
commands:
|
|
--enable|-e option Enable option
|
|
--disable|-d option Disable option
|
|
--module|-m option Turn option into a module
|
|
--set-str option string
|
|
Set option to "string"
|
|
--set-val option value
|
|
Set option to value
|
|
--undefine|-u option Undefine option
|
|
--state|-s option Print state of option (n,y,m,undef)
|
|
|
|
--enable-after|-E beforeopt option
|
|
Enable option directly after other option
|
|
--disable-after|-D beforeopt option
|
|
Disable option directly after other option
|
|
--module-after|-M beforeopt option
|
|
Turn option into module directly after other option
|
|
|
|
commands can be repeated multiple times
|
|
|
|
options:
|
|
--file config-file .config file to change (default .config)
|
|
--keep-case|-k Keep next symbols' case (dont' upper-case it)
|
|
|
|
config doesn't check the validity of the .config file. This is done at next
|
|
make time.
|
|
|
|
By default, config will upper-case the given symbol. Use --keep-case to keep
|
|
the case of all following symbols unchanged.
|
|
|
|
config uses 'CONFIG_' as the default symbol prefix. Set the environment
|
|
variable CONFIG_ to the prefix to use. Eg.: CONFIG_="FOO_" config ...
