 -----------------------------
 
-This example cron check last cron jobs results. If they were unsuccessfull 10 times in row, it sends email to user.
+This sample cron job checks for any unreported failed jobs for each job class
+provided in your ``CRON_CLASSES`` list, and reports them as necessary. The
+default process is to email all the users specified in the
+``ADMINS`` settings list when a job fails more than 10 times in a row.

+To configure the minimum number of failures before a report, you can either
