#       @(#)Makefile.tahoe      1.8 (Berkeley) %G%
#
# Makefile for 4.3 BSD
#
# This makefile is constructed from a machine description:
#       config machineid
# Most changes should be made in the machine description
#       /sys/conf/``machineid''
# after which you should do
#        config machineid
# Generic makefile changes should be made in
#       /sys/conf/Makefile.``machinetype''
# after which config should be rerun for all machines.
#
# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE INVISIBLE TO MAKEFILE
#       IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
#
# -DTRACE       compile in kernel tracing hooks
# -DQUOTA       compile in file system quotas
