  cat <<END_OF_USAGE
This script builds mainline modules. It is used from other build scripts that
are run on build servers, and is meant to build both AOSP and internal
variants of the modules.

Basic usage:
  \$ packages/modules/common/build/build_unbundled_mainline_module.sh \
      --dist_dir out/dist/mainline_modules_arm64 \
      --product module_arm64 \
      -j8

Arguments:
   --dist_dir <dir>    a dist directory to store the outputs in.
   --product <product> a target product to use when building.
   \$@ all other arguments are passed through to soong_ui.bash verbatim.
