6: # This makefile is constructed from a machine description:
7: # config machineid
8: # Most changes should be made in the machine description
9: # /sys/arch/mac68k/conf/``machineid''
10: # after which you should do
11: # config machineid
12: # Machine generic makefile changes should be made in
13: # /sys/arch/mac68k/conf/Makefile.mac68k
14: # after which config should be rerun for all machines of that type.
15: #
16: # N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
17: # IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
