4 # at the bottom of each `MD' ${MACHINE}/conf/Makefile.${MACHINE}.
5 #
6 # Each target in this file should be protected with `if !target(target)'
7 # or `if !commands(target)' and each variable should only be conditionally
8 # assigned `VAR ?= VALUE', so that everything can be overriden.

10 # DEBUG is set to -g if debugging.
11 # PROF is set to -pg if profiling.
12 #
13 # To specify debugging, add the config line: makeoptions DEBUG="-g"
14 # A better way is to specify -g only for a few files.
