# Example post-processing script for sending a Prowl notification upon
# completion. See http://www.prowlapp.com/ for more info.

use strict;

use File::Basename qw(basename);
use WebService::Prowl;

# set your Prowl API key here
my $apikey = '';

my $file = basename $ARGV[0];
my $prowl = WebService::Prowl->new(apikey => $apikey);

Add example on how to use post-processing scripts for sending custom notification when slicing is done.
