  55
  56 C4::Letters - Give functions for Letters management
  57
  58 =head1 SYNOPSIS
  59
  60   use C4::Letters;
  61
  62 =head1 DESCRIPTION
  63
  64   "Letters" is the tool used in Koha to manage informations sent to the patrons and/or the library. This include some cron jobs like
  65   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)
  66
  67   Letters are managed through "alerts" sent by Koha on some events. All "alert" related functions are in this module too.
  68
  69 =head2 GetLetters([$module])
  70
  71   $letters = &GetLetters($module);
  72   returns informations about letters.
  73   if needed, $module filters for letters given module
  74
  75   DEPRECATED - You must use Koha::Notice::Templates instead
  76   The group by clause is confusing and can lead to issues

 278     C<&SendAlerts> sends an email notice directly to a patron or a vendor.
 279
 280     Currently it supports ($type):
 281       - claim serial issues (claimissues)
 282       - claim acquisition orders (claimacquisition)
 283       - send acquisition orders to the vendor (orderacquisition)
 284       - notify patrons about newly received serial issues (issue)
 285       - notify patrons when their account is created (members)
 286
 287     Returns undef or { error => 'message } on failure.
 288     Returns true on success.
