=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])
$letters = &GetLetters($module);
returns informations about letters.
if needed, $module filters for letters given module
DEPRECATED - You must use Koha::Notice::Templates instead
The group by clause is confusing and can lead to issues

=head2 SendAlerts
my $err = &SendAlerts($type, $externalid, $letter_code);
Parameters:
- $type : the type of alert
- $externalid : the id of the "object" to query
- $letter_code : the notice template to use
C<&SendAlerts> sends an email notice directly to a patron or a vendor.
Currently it supports ($type):
- claim serial issues (claimissues)
- claim acquisition orders (claimacquisition)
- send acquisition orders to the vendor (orderacquisition)
- notify patrons about newly received serial issues (issue)
- notify patrons when their account is created (members)
Returns undef or { error => 'message } on failure.
Returns true on success.

Return message_id on success
Parameters
* letter - required; A letter hashref as returned from GetPreparedLetter
* message_transport_type - required; One of the available mtts
* borrowernumber - optional if 'to_address' is passed; The borrowernumber of the patron we enqueuing the notice for
* to_address - optional if 'borrowernumber' is passed; The destination email address for the notice (defaults to patron->notice_email_address)
* from_address - optional; The from address for the notice, defaults to patron->library->from_email_address
* reply_address - optional; The reply address for the notice, defaults to patron->library->reply_to

This function's parameter hash reference takes the following

borrowernumber : who the message is to be sent
letter_code : type of message being sent (e.g. PASSWORD_RESET)
message_id : the message_id of the message. In that case the sub will return only 1 result
limit : maximum number of messages to send
This function returns an array of matching hash referenced rows from
message_queue with some borrower information added.
