# This script selects the build configuration to use for Gralloc.
# The Arm Reference Gralloc supports multiple versions of Android and Gralloc APIs.
# This script must be used before the build stage to select what to build, consistently with the target Android system.
#
# If `lunch` has been run then the script configures the build automatically from the environment.
# When not in a 'lunched' shell, the Android version can be set to 'N' by specifying `ANDROID_N=y`.

# The script does not check that the combination of options specified is valid.
