// Added automatically by a large-scale-change that took the approach of

// Please consider splitting the single license below into multiple licenses,
// taking care not to lose any license_kind information, and overriding the

//
// For unused files, consider creating a 'filegroup' with "//visibility:private"
// to attach the license to, and including a comment whether the files may be
