Any warnings or errors will be printed on the [stdout]. If [sanitize] is [Some fn], a shell script will be written
into the file [fn] with commands to delete the offending files. The command will return a pair [(fatal, penalties)]
where [fatal] is [true] when serious hygiene violations have been spotted, and [penalties] is a list of laws and
messages describing the offenses. *)
