5# This makefile is constructed from a machine description:
6#	config machineid
7# Most changes should be made in the machine description
8#	/sys/arch/sun2/conf/``machineid''
9# after which you should do
10#	config machineid
11# Machine generic makefile changes should be made in
12#	/sys/arch/sun2/conf/Makefile.sun2
13# after which config should be rerun for all machines of that type.
14#
15# To specify debugging, add the config line: makeoptions DEBUG="-g"
16# A better way is to specify -g only for a few files.
