-# Makefile for NetBSD
-#
-# This makefile is constructed from a machine description:
-#	config machineid
-# Most changes should be made in the machine description
-#	/sys/arch/pica/conf/``machineid''
-# after which you should do
-#	config machineid
-# Machine generic makefile changes should be made in
-#	/sys/arch/pica/conf/Makefile.pica
-# after which config should be rerun for all machines of that type.
-#
-# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE 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
-
-# DEBUG is set to -g if debugging.
-# PROF is set to -pg if profiling.
