Description

Checks if a yaml header option was specified. If not, generates a feedback message. If yes, zooms in on the YAML header option so you can use check_equal to verify equality.

  not_found_msg = NULL, append = TRUE, ...)

append	Whether or not to append the feedback to feedback built in previous states.
...	S3 stuff
