# soong_module_type: Soong module type, e.g. android_app, cc_binary

# is_build_prop: build.prop in each partition, see sysprop.mk.
# is_notice_file: NOTICE.xml.gz in each partition, see Makefile.
# is_dexpreopt_image_profile: see the usage of DEXPREOPT_IMAGE_PROFILE_BUILT_INSTALLED in Soong and Make
