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
|
|
|
|
$letters = &getletters($category);
|
|
returns informations about letters.
|
|
if needed, $category filters for letters given category
|
|
Create a letter selector with the following code
