8# Makefile for FreeBSD

10# This makefile is constructed from a machine description:
11#	config machineid
12# Most changes should be made in the machine description
13#	/sys/i386/conf/``machineid''
14# after which you should do
15#	 config machineid
16# Generic makefile changes should be made in
17#	/sys/i386/conf/Makefile.i386
18# after which config should be rerun for all machines.
19#
