Manipulate options in a .config file from the command line.
|
||||
Usage:
|
||||
$myname 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)
|
||||
|
||||
$myname doesn't check the validity of the .config file. This is done at next
|
||||
make time.
|
||||
|
||||
By default, $myname will upper-case the given symbol. Use --keep-case to keep
|
||||
the case of all following symbols unchanged.
|
||||
|
||||
$myname uses 'CONFIG_' as the default symbol prefix. Set the environment
|
||||
variable CONFIG_ to the prefix to use. Eg.: CONFIG_="FOO_" $myname ...
