5# This makefile is constructed from a machine description:
6#	config machineid
7# Most changes should be made in the machine description
8#	/sys/arch/alpha/conf/``machineid''
9# after which you should do
10#	config machineid
11# Machine generic makefile changes should be made in
12#	/sys/arch/alpha/conf/Makefile.alpha
13# after which config should be rerun for all machines of that type.

17# DEBUG is set to -g if debugging.
18# PROF is set to -pg if profiling.
19#
20# To specify debugging, add the config line: makeoptions DEBUG="-g" 
21# A better way is to specify -g only for a few files.
