# Makefile for NetBSD
#
# This makefile is constructed from a machine description:
#	config machineid
# Most changes should be made in the machine description
#	/sys/arch/<arch>/conf/``machineid''
# after which you should do
#	config machineid
# Machine generic makefile changes should be made in
#	/sys/arch/arm/conf/Makefile.arm
# after which config should be rerun for all machines of that type.

# DEBUG is set to -g if debugging.
# PROF is set to -pg if profiling.
