9#	config machineid
10# Most changes should be made in the machine description
11#	/sys/i386/conf/``machineid''
12# after which you should do
13#	 config machineid
14# Generic makefile changes should be made in
15#	/sys/conf/Makefile.i386
16# after which config should be rerun for all machines.
17#

19# Which version of config(8) is required.
