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