Writes a configuration file where as many symbols as possible are set to 'n'.
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/
# See examples/ for another way to implement this script
import kconfiglib
def main():
kconf = kconfiglib.standard_kconfig(__doc__)
# Avoid warnings that would otherwise get printed by Kconfiglib for the
# following:
# 1. Assigning a value to a symbol without a prompt, which never has any
# effect
# 2. Assigning values invalid for the type (only bool/tristate symbols
# accept 0/1/2, for n/m/y). The assignments will be ignored for other
# symbol types, which is what we want.
kconf.warn = False
for sym in kconf.unique_defined_syms:
sym.set_value(2 if sym.is_allnoconfig_y else 0)
kconf.warn = True
