3# Makefile for 4.4 BSD
4#
5# This makefile is constructed from a machine description:
6#	config machineid
7# Most changes should be made in the machine description
8#	/sys/conf/``machineid''
9# after which you should do
10#	 config machineid
11# Machine generic makefile changes should be made in
12#	/sys/conf/Makefile.``machinetype''
13# after which config should be rerun for all machines of that type.
14#
15# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
16#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
