      7 #	config machineid
      8 # Most changes should be made in the machine description
      9 #	/sys/arch/xen/conf/``machineid''
     10 # after which you should do
     11 #	config machineid
     12 # Machine generic makefile changes should be made in
     13 #	/sys/arch/xen/conf/Makefile.xen
     14 # after which config should be rerun for all machines of that type.
     15 #
     16 # To specify debugging, add the config line: makeoptions DEBUG="-g"
     17 # A better way is to specify -g only for a few files.
