=head1 NAME

gather_print_notices - Print waiting print notices

=head1 SYNOPSIS

gather_print_notices output_directory [-s|--split] [--html] [--csv] [--ods] [--letter_code=LETTER_CODE] [-e|--email=your_email@example.org] [-h|--help]

Will print all waiting print notices to the output_directory.

The generated filename will be notices-TODAY.[csv|html|ods] or notices-TODAY-BRANCHCODE.[csv|html|ods] if the --split parameter is given.

=head1 OPTIONS

=over

=item B<output_directory>

Define the output directory where the files will be generated.

=item B<--send|--nosend>

After files have been generated, messages status is changed from 'pending' to
'sent'. This is the default action, without this parameter or with --send.
Using --nosend, the message status is not changed.

=item B<-s|--split>

Split messages into separate files by borrower home library to OUTPUT_DIRECTORY/notices-CURRENT_DATE-BRANCHCODE.[csv|html|ods]

=item B<--html>

Generate the print notices in a html file (default is --html, if --csv and --ods are not given).

=item B<--csv>

Generate the print notices in a csv file.
If you use this parameter, the template should contain 2 lines.
The first one the csv headers and the second one the value list.

For example:
cardnumber:patron:email:item
<<borrowers.cardnumber>>:<<borrowers.firstname>> <<borrowers.surname>>:<<borrowers.email>>:<<items.barcode>>

You have to combine this option with one (and only one) letter_code.

=item B<--ods>

Generate the print notices in a ods file.

This is the same as the csv parameter but using csv2odf to generate an ods file instead of a csv file.

=item B<--letter_code>

Filter print messages by letter_code.
Several letter_code parameters can be given.

=item B<-e|--email>

Repeatable.
E-mail address to send generated files to.

=item B<-h|--help>

Print a brief help message
