-// This could be achieved with a regex like:
-// (?<before><message name="(?<id>[^"]*)"[^>]*>[^<]*)The Chromium Authors(?<after>[^<]*<\/message>)
-// Until that is implemented, when adding to or modifying this list, you must manually find the

-// 'npm run delete_string_translations -- ...'.
-// Otherwise, languages apart from US English will not get updated.
