-        As of Bugzilla 2.20, users can configure Bugzilla to regularly annoy 
-        them at regular intervals, by having Bugzilla execute saved searches
-        at certain times and emailing the results to the user.  This is known
-        as "Whining".  The process of configuring Whining is described 
-        in <xref linkend="whining"/>, but for it to work a Perl script must be
-        executed at regular intervals.

-        This can be done by adding the following command as a daily
-        crontab entry, in the same manner as explained above for bug
-        graphs. This example runs it every 15 minutes.

-          Whines can be executed as often as every 15 minutes, so if you specify
-          longer intervals between executions of whine.pl, some users may not 
-          be whined at as often as they would expect.  Depending on the person,
-          this can either be a very Good Thing or a very Bad Thing.

-          Windows does not have 'cron', but it does have the Task
-          Scheduler, which performs the same duties. There are also
-          third-party tools that can be used to implement cron, such as
