# This script checks that the runtime version number constant in the compiler
# source and in the runtime source is the same.
#
# A distro can be made of the protobuf sources with only a subset of the
# languages, so if the compiler depended on the Objective C runtime, those
# builds would break. At the same time, we don't want the runtime source
# depending on the compiler sources; so two copies of the constant are needed.
