5: # many `MI' definitions that should end up in here, but they are not yet.
6: #
7: # Each target in this file should be protected with `if !target(target)'
8: # or `if !commands(target)' and each variable should only be conditionally
9: # assigned `VAR ?= VALUE', so that everything can be overriden.
10: #
11: # DEBUG is set to -g if debugging.
12: # PROF is set to -pg if profiling.

14: # To specify debugging, add the config line: makeoptions DEBUG="-g"
15: # A better way is to specify -g only for a few files.
