# Works like 'make olddefconfig', updating an old .config file or creating a
# new one by filing in default values for all new symbols. This is the same as
# picking the default selection for all symbols in oldconfig, or entering the
# menuconfig interface and immediately saving.
#
# The default output filename is '.config'. A different filename can be passed
# in the KCONFIG_CONFIG environment variable.
