  22 membership_expiry.pl - cron script to put membership expiry reminders into the message queue
  23
  24 =head1 SYNOPSIS
  25
  26 ./membership_expiry.pl -c
  27
  28 or, in crontab:
  29
  30 0 1 * * * membership_expiry.pl -c
  31
  32 =head1 DESCRIPTION
  33
  34 This script sends membership expiry reminder notices to patrons.
  35 It queues them in the message queue, which is processed by
  36 the process_message_queue.pl cronjob.
  37
  38 =head1 OPTIONS
  39
  40 =over 8
  41
  42 =item B<--help>
  43
  44 Print a brief help message and exits.
  45
  46 =item B<--man>
  47
  48 Prints the manual page and exits.
  49
  50 =item B<-v>
  51
  52 Verbose. Without this flag set, only fatal errors are reported.
  53
  54 =item B<-n>
  55
  56 Do not send any email. Membership expire notices that would have been sent to
  57 the patrons are printed to standard out.
  58
  59 =item B<-c>
  60
  61 Confirm flag: Add this option. The script will only print a usage
  62 statement otherwise.
  63
  64 =item B<-branch>
  65
  66 Optional branchcode to restrict the cronjob to that branch.
  67
  68 =item B<-before>
  69
  70 Optional parameter to extend the selection with a number of days BEFORE
  71 the date set by the preference.
  72
  73 =item B<-after>
  74
  75 Optional parameter to extend the selection with a number of days AFTER
  76 the date set by the preference.
  77
  78 =item B<-letter>
  79
  80 Optional parameter to use another notice than the default one.
  81
  82 =back
  83
  84 =head1 CONFIGURATION
  85
  86 The content of the messages is configured in Tools -> Notices and slips. Use the MEMBERSHIP_EXPIRY notice.
  87
  88 Typically, messages are prepared for each patron when the memberships are going to expire.
  89
  90 These emails are staged in the outgoing message queue, as are messages
  91 produced by other features of Koha. This message queue must be
  92 processed regularly by the
  93 F<misc/cronjobs/process_message_queue.pl> program.
  94
  95 In the event that the C<-n> flag is passed to this program, no emails
  96 are sent. Instead, messages are sent on standard output from this
  97 program.
  98
  99 Notices can contain variables enclosed in double angle brackets like
 100 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
 101 specific to the soon expiring members.
 102 Available variables are:
 103
 104 =over
 105
 106 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
 107
 108 any field from the borrowers table
 109
 110 =item E<lt>E<lt>branches.*E<gt>E<gt>
 111
 112 any field from the branches table
 113
 114 =back
