# Makefile for FreeBSD

# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arm/conf/``machineid''
# after which you should do
# config machineid
# Generic makefile changes should be made in
# /sys/conf/Makefile.arm
# after which config should be rerun for all machines.

# Which version of config(8) is required.
