-// 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
-// used in the current project.

-// large-scale-change included anything that looked like it might be a license
-// text as a license_text. e.g. LICENSE, NOTICE, COPYING etc.
