=head1 NAME
Wiki::Toolkit::Plugin::RSS::Reader - retrieve RSS feeds for inclusion in Wiki::Toolkit nodes
=head1 DESCRIPTION
Use this L<Wiki::Toolkit> plugin to retrieve an RSS feed from a given URL so
that you can include it in a wiki node.
=head1 SYNOPSIS
use Wiki::Toolkit::Plugin::RSS::Reader;
my $rss = Wiki::Toolkit::Plugin::RSS::Reader->new(
url => 'http://example.com/feed.rss'
);
my @items = $rss->retrieve;
=head1 USAGE
This is a plugin for L<Wiki::Toolkit>, a toolkit for building wikis; therefore
please consult the documentation for L<Wiki::Toolkit> for relevant information.
This module can, however, be used standalone if you wish.
=head1 METHODS
=head2 C<new>
my $rss = Wiki::Toolkit::Plugin::RSS::Reader->new([options]);
Create a new RSS reader. Valid options are C<url> or C<file> (a path to an
RSS file); only one can be specified.
=head2 C<retrieve>
my @items = $rss->retrieve;
C<retrieve> will return an array of hashes, one for each item in the RSS
feed. The hashes contain three items, C<title>, C<link>, and C<description>.
If the URL or file you specified cannot be retrieved/read, C<retrieve> will
return undef rather than blowing up and surprising the person reading your
wiki. If you want, you can specify C<debug> to be 1 in the options to
C<new>, which will cause the module to croak instead of failing silently.
