# The WKTs have to be checked in to support the CocoaPods and Xcode builds. This
# generule and test ensure the source are current.
#
# Within the ":objectivec" target, the outputs of the genrule are then used to
# ensure they are always "current". This implementation is basically the same
# has how the WKTs are handled in src/google/protobuf/BUILD.bazel for the C++
# version. They share the potential downsides around layer checks and that
# someone could #include the header with the `wkt/` prefix on the name.
