# -d: debug build, modifies default build flags to produce binaries best suited for debugging.

# You can customize the targets that are built using targets='...'. Use targets='all' to build all targets.
# By default, we only build the 'mpw' target.
# See targets_all for all possible targets as well as the features they support and require.
