=head1 NAME
C4::Letters - Give functions for Letters management
=head1 SYNOPSIS
use C4::Letters;
=head1 DESCRIPTION
"Letters" is the tool used in Koha to manage informations sent to the patrons and/or the library. This include some cron jobs like
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)
Letters are managed through "alerts" sent by Koha on some events. All "alert" related functions are in this module too.
=head2 GetLetters([$module])

returns informations about letters.
if needed, $module filters for letters given module
