# or defconfig, it is loaded as 0 (possibly triggering a user prompt during 'ct-ng oldconfig').
# If the value of CONFIG_VERSION is older than CONFIG_VERSION_CURRENT, we'll advice the user
# to run the configuration through an upgrade. If it is newer, we'll error out - I have no
# crystal orb to perform the downgrade.

# Hack to make kconfig save/load the value for CONFIG_VERSION. Set to empty value (for
# normal operations like 'ct-ng menuconfig'); 'load' for creating a configuration from a (potentially)
# old file, i.e. 'ct-ng <sample>' or 'ct-ng oldconfig'; 'save' for saving the current configuration,
# i.e. 'ct-ng saveconfig' or 'ct-ng savedefconfig'.
