  54
  55 =head1 SYNOPSIS
  56
  57   use C4::Letters;
  58
  59 =head1 DESCRIPTION
  60
  61   "Letters" is the tool used in Koha to manage informations sent to the patrons and/or the library. This include some cron jobs like
  62   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)
  63
  64   Letters are managed through "alerts" sent by Koha on some events. All "alert" related functions are in this module too.
  65
  66 =head2 GetLetters([$module])
  67
  68   $letters = &GetLetters($module);
  69   returns informations about letters.
  70   if needed, $module filters for letters given module
