automatic_renewals.pl - cron script to renew loans
=head1 SYNOPSIS
./automatic_renewals.pl [-c|--confirm] [-s|--send-notices] [-d|--digest] [-b|--digest-per-branch] [-v|--verbose]
or, in crontab:
# Once every day for digest messages
0 3 * * * automatic_renewals.pl -c -d
# Three times a day for non digest messages
0 0,8,16 * * * automatic_renewals.pl -c
=head1 DESCRIPTION
This script searches for issues scheduled for automatic renewal
(issues.auto_renew). If there are still renews left (Renewals allowed)
and the renewal isn't premature (No Renewal before) the issue is renewed.
=head1 OPTIONS
=over
=item B<-s|--send-notices>
DEPRECATED: The system preference AutoRenewalNotices should be used to determine
whether notices are sent or not
Send AUTO_RENEWALS notices to patrons if the auto renewal has been done.
=item B<-v|--verbose>
Print report to standard out.
=item B<-c|--confirm>
Without this parameter no changes will be made
=item B<-b|--digest-per-branch>
Flag to indicate that generation of message digests should be
performed separately for each branch.
A patron could potentially have loans at several different branches
There is no natural branch to set as the sender on the aggregated
message in this situation so the default behavior is to use the
borrowers home branch. This could surprise to the borrower when
message sender is a library where they have not borrowed anything.
Enabling this flag ensures that the issuing library is the sender of
the digested message. It has no effect unless the borrower has
chosen 'Digests only' on the advance messages.

Therefore, it is unlikely that this script will actually produce any messages to be sent.
