### BUILD OPTIONS
# Set the next two variables to ANYTHING that is not null to enable them

# Tweak kernel options prior to a build via nconfig
_makenconfig=

# Only compile active modules to VASTLY reduce the number of modules built and
# the build time.
#
# To keep track of which modules are needed for your specific system/hardware,
# give module_db a try: https://aur.archlinux.org/packages/modprobed-db
# This PKGBUILD reads the database kept if it exists
#
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db

# Use the current kernel's .config file
# Enabling this option will use the .config of the RUNNING kernel rather than
# the ARCH defaults. Useful when the package gets updated and you already went
# through the trouble of customizing your config options.  NOT recommended when
# a new kernel is released, but again, convenient for package bumps.

# Enable/Disable debug options
# Set 'y' to enable, 'n' to force disable debug options if already enabled in your
# .config file or leave empty to ignore debug options.
