# Makefile for OpenBSD/Kbus
#
#  Edited by Philip A. Nelson
#
# This makefile is constructed from a machine description:
#	config machineid
# Most changes should be made in the machine description
#	/sys/arch/kbus/conf/``machineid''
# after which you should do
#	 config machineid
# Generic makefile changes should be made in
#	/sys/arch/kbus/conf/Makefile.kbus
# after which config should be rerun for all machines.
#
# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE INVISIBLE TO MAKEFILE
#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
#
# -DTRACE	compile in kernel tracing hooks
# -DQUOTA	compile in file system quotas
