=head1 NAME

XML::RSS::PicLens - Create a PicLens compatible RSS feed

=head1 VERSION

This document describes XML::RSS::PicLens version 0.04

=cut

our $VERSION = '0.04';

=head1 SYNOPSIS

  use XML::RSS::PicLens;

  my $feed = XML::RSS::PicLens->new;
  $feed->add_content(
    link      => 'foo.jpg',
    image     => 'foo.jpg',
    thumbnail => 'thumbs/foo.jpg',
    title     => 'An bootiful foo'

=head1 DESCRIPTION

PicLens is an immersive media browser that can be launched directly from
a web browser when visiting a supported site. It uses RSS autodiscovery
to locate an RSS feed describing the available media. This module
provides a simple interface for generating such a feed.

See L for more information.

=head1 INTERFACE

=head2 C<< new >>

Create a new C object. C is a
subclass of L; any arguments to C are passed to the
superclass's constructor. The RSS version defaults to 2.0.

=cut

sub new {
  my $class = shift;
  my $self = $class->SUPER::new( version => '2.0', @_ );

  $self->add_module(
    prefix => 'media',
    uri    => 'http://search.yahoo.com/mrss'
  );

  return $self;
}

=head2 C<< add_content >>

Add media content to the feed:

    $feed->add_content(
        link            => 'foo.jpg',
        content         => 'foo.jpg',
        thumbnail       => 'thumbs/foo.jpg',
        title           => 'An bootiful foo',
        content_type    => 'image/jpeg',
        thumbnail_type  => 'image/jpeg',
    );

At least one of C, C must be supplied. Optionally you
may supply C and C. If these are omitted they will default </td>
