# This makefile is constructed from a machine description:

# config machineid
|
|
# Most changes should be made in the machine description
|
|
# /sys/i386/conf/``machineid''
|
|
# after which you should do
|
|
# config machineid
|
|
# Generic makefile changes should be made in
|
|
# /sys/i386/conf/Makefile.i386
|
|
# after which config should be rerun for all machines.
|

# N.B.: DEPENDENCIES ON FOLLOWING FLAGS ARE INVISIBLE TO MAKEFILE
|

# IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
