-=head1 NAME
-
-rt-email-dashboards - Send email dashboards
-
-=head1 SYNOPSIS
-
- /opt/rt3/local/sbin/rt-email-dashboards [options]
-
-=head1 DESCRIPTION
-
-This tool will send users email based on how they have subscribed to
-dashboards. A dashboard is a set of saved searches, the subscription controls
-how often that dashboard is sent and how it's displayed.
-
-Each subscription has an hour, and possibly day of week or day of month. These
-are taken to be in the user's timezone if available, UTC otherwise.
-
-=head1 SETUP
-
-You'll need to have cron run this script every hour. Here's an example crontab
-entry to do this.
-
- 0 * * * * @PERL@ /opt/rt3/local/sbin/rt-email-dashboards
-
-This will run the script every hour on the hour. This may need some further
-tweaking to be run as the correct user.
-
-=head1 OPTIONS
-
-This tool supports a few options. Most are for debugging.
-
-=over 8
-
-=item --help
-
-Display this documentation
-
-=item --dryrun
-
-Figure out which dashboards would be sent, but don't actually generate them
-
-=item --epoch SECONDS
-
-Instead of using the current time to figure out which dashboards should be
-sent, use SECONDS (usually since midnight Jan 1st, 1970, so C<1192216018> would
-be Oct 12 19:06:58 GMT 2007).
-
-=item --verbose
-
-Print out some tracing information (such as which dashboards are being
-generated and sent out)
-
-=item --debug
-
-Print out more tracing information (such as each user and subscription that is
-being considered)
-
-=item --all
-
-Ignore subscription frequency when considering each dashboard (should only be
-used with --dryrun)
-
-=back
-
-=cut
