 177 =head1 NAME
 178
 179 labels/label-create-pdf.pl - A script for creating a pdf export of labels and label batches in Koha
 180
 181 =head1 ABSTRACT
 182
 183 This script provides the means of producing a pdf of labels for items either individually, in groups, or in batches from within Koha.
 184
 185 =head1 USAGE
 186
 187 This script is intended to be called as a cgi script although it could be easily modified to accept command line parameters. The script accepts four single
 188 parameters and two "multiple" parameters as follows:
 189
 190     C<batch_id>         A single valid batch id to export.
 191     C<template_id>      A single valid template id to be applied to the current export. This parameter is manditory.
 192     C<layout_id>        A single valid layout id to be applied to the current export. This parameter is manditory.
 193     C<start_label>      The number of the label on which to begin the export. This parameter is optional.
 194     C<lable_ids>        A single valid label id to export. Multiple label ids may be submitted to export multiple labels.
 195     C<item_numbers>     A single valid item number to export. Multiple item numbers may be submitted to export multiple items.
 196
 197 B<NOTE:> One of the C<batch_id>, C<label_ids>, or C<item_number> parameters is manditory. However, do not pass a combination of them or bad things might result.
