doc = """Hack to make github.com/bazelbuild/remote-apis work with rules_go v0.41.0.
Starting with version v0.41.0, rules_go no longer ships with the @go_googleapis external
repository: https://github.com/bazelbuild/rules_go/releases/tag/v0.41.0. As per the release notes,
Go code imported generated Google API .pb.go files should use the @org_golang_google_genproto
repository instead (https://github.com/googleapis/go-genproto).
As of 2023-05-26, the github.com/googleapis/go-genproto Go module has been broken into smaller
submodules as a usability improvements for customers that do not depend on Google Cloud:
https://github.com/googleapis/go-genproto/issues/1015. This means some former @go_googleapis
dependencies are now found in Go modules such as google.golang.org/genproto/googleapis/api and
google.golang.org/genproto/googleapis/rpc. In Bazel terms, the corresponding Gazelle-generated
external repositories will be @org_golang_google_genproto_googleapis_api and
@com_github_bazelbuild_remote_apis, respectively.
Unfortunately, as of 2023-10-30 the https://github.com/bazelbuild/remote-apis Go module is still
distributed with BUILD files that reference the @go_googleapis repository:
https://github.com/bazelbuild/remote-apis/blob/6c32c3b917cc5d3cfee680c03179d7552832bb3f/build/bazel/remote/execution/v2/go/BUILD#L13.
As a compatibility hack, this repository rule provides a fake @go_googleapis repository that
aliases the Bazel labels required by https://github.com/bazelbuild/remote-apis to point to the
correct targets within @org_golang_google_genproto, @org_golang_google_genproto_googleapis_api,
etc.
We should delete this rule if/when https://github.com/bazelbuild/remote-apis is updated to work
with more recent versions of rules_go.
