-For cronjobs, email only once for repeated failures, and for success after failure.
-
-Meant for use in cronjobs where LOG_MESSAGE or STDIN represents an error,
-but we only want to output that to STDOUT if we've seen this type of
-error ERRORS(default 3) number of times in a row, then we don't
-want to output anything again until we've seen a success (an empty LOG_MESSAGE).
-
-Logs LOG_MESSAGE or STDIN to ~/.cron_errors/LOG_NAME, and keeps
-state in the same directory.
