"""
|
|
Saves a minimal configuration file that only lists symbols that differ in value
|
|
from their defaults. Loading such a configuration file is equivalent to loading
|
|
the "full" configuration file.
|
|
|
|
Minimal configuration files are handy to start from when editing configuration
|
|
files by hand.
|
|
|
|
The default input configuration file is '.config'. A different input filename
|
|
can be passed in the KCONFIG_CONFIG environment variable.
|
|
|
|
Note: Minimal configurations can also be generated from within the menuconfig
|
|
interface.
