In this PR – [https://github.com/elastic/elasticsearch/pull/14247/files](https://github.com/elastic/elasticsearch/pull/14247/files) I see the rest-api-spec JSON files being added. Are they written manually or automatically? I am very suspicious they are generated automatically. Could someone point me to the code that gets them generated?

They often receive a fair bit of copy and paste but they are written by  
hand. They exist so elasticsearch can share tests with its clients.
