# USAGE
# [targets='...'] [mpw_feature=0|1 ...] [CFLAGS='...'] [LDFLAGS='...'] ./build [cc arguments ...]
#
# By default, you should only need to run ./build
#
# 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.
#
# Several features can be enabled or disabled using feature flags.
# See the Features section for an overview of the features, their default setting, their meaning and their dependencies.
# You will need to have each of the feature's dependencies installed for the build to succeed with that feature enabled.
#
# Finally, the C compiler can be tuned using CFLAGS, LDFLAGS and compiler arguments passed to the script.
