41.1Sfvdl#
51.1Sfvdl# This makefile is constructed from a machine description:
61.1Sfvdl#	config machineid
71.1Sfvdl# Most changes should be made in the machine description
81.1Sfvdl#	/sys/arch/amd64/conf/``machineid''
91.1Sfvdl# after which you should do
101.1Sfvdl#	config machineid
111.1Sfvdl# Machine generic makefile changes should be made in
121.1Sfvdl#	/sys/arch/amd64/conf/Makefile.amd64
131.1Sfvdl# after which config should be rerun for all machines of that type.
141.1Sfvdl#
151.1Sfvdl# To specify debugging, add the config line: makeoptions DEBUG="-g"
161.1Sfvdl# A better way is to specify -g only for a few files.
