# This script freezes APIs of a sysprop_library after checking compatibility
# between latest API and current API.
#
# Usage: freeze-sysprop-api-files.sh <modulePath> <moduleName>
#
# <modulePath>: the directory, either relative or absolute, which holds the
# Android.bp file defining sysprop_library.
#
# <moduleName>: the name of sysprop_library to freeze API.
#
# Example:
# $ . build/envsetup.sh && lunch aosp_arm64-user
# $ . build/soong/scripts/freeze-sysprop-api-files.sh \
#       system/libsysprop/srcs PlatformProperties
