# Makefile for NetBSD
#
# This makefile is constructed from a machine description:
#	config machineid
# Most changes should be made in the machine description
#	/sys/arch/<machine>/conf/``machineid''
# after which you should do
#	config machineid
# CPU generic makefile changes should be made in
#	/sys/arch/sh3/conf/Makefile.sh3
# after which config should be rerun for all machines of that type.
#
# To specify debugging, add the config line: makeoptions DEBUG="-g"
# A better way is to specify -g only for a few files.
#
#	makeoptions DEBUGLIST="uvm* trap if_*"
