  56 =head1 NAME
  57
  58 C4::Letters - Give functions for Letters management
  59
  60 =head1 SYNOPSIS
  61
  62   use C4::Letters;
  63
  64 =head1 DESCRIPTION
  65
  66   "Letters" is the tool used in Koha to manage informations sent to the patrons and/or the library. This include some cron jobs like
  67   late issues, as well as other tasks like sending a mail to users that have subscribed to a "serial issue alert" (= being warned every time a new issue has arrived at the library)
  68
  69   Letters are managed through "alerts" sent by Koha on some events. All "alert" related functions are in this module too.
  70
  71 =head2 GetLetters([$module])
  72
  73   $letters = &GetLetters($module);
  74   returns informations about letters.
  75   if needed, $module filters for letters given module
  76
  77   DEPRECATED - You must use Koha::Notice::Templates instead
  78   The group by clause is confusing and can lead to issues

 280     C<&SendAlerts> sends an email notice directly to a patron or a vendor.
 281
 282     Currently it supports ($type):
 283       - claim serial issues (claimissues)
 284       - claim acquisition orders (claimacquisition)
 285       - send acquisition orders to the vendor (orderacquisition)
 286       - notify patrons about newly received serial issues (issue)
 287       - notify patrons when their account is created (members)
 288
 289     Returns undef or { error => 'message } on failure.
 290     Returns true on success.
