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, $module filters for letters given module =cut sub GetLetters { my ($filters) = @_; my $module = $filters->{module}; my $code = $filters->{code}; my $branchcode = $filters->{branchcode}; my $dbh = C4::Context->dbh; my $letters = $dbh->selectall_arrayref( q| SELECT module, code, branchcode, name FROM letter WHERE 1 | .
