# Works like 'make alldefconfig'. Verified by the test suite to generate
# identical output to 'make alldefconfig' for all ARCHes.
#
# The default output filename is '.config'. A different filename can be passed
# in the KCONFIG_CONFIG environment variable.
#
# Usage for the Linux kernel:
#
#   $ make [ARCH=<arch>] scriptconfig SCRIPT=Kconfiglib/alldefconfig.py
