Simple utility for setting configuration values from the command line. |
|
|
|
Sample usage: |
|
|
|
$ setconfig FOO_SUPPORT=y BAR_BITS=8 |
|
|
|
Note: Symbol names should not be prefixed with 'CONFIG_'. |
|
|
|
The exit status on errors is 1. |
|
|
|
The default input/output configuration file is '.config'. A different filename |
|
can be passed in the KCONFIG_CONFIG environment variable. |
