=head1 DESCRIPTION

This module will match an RSS item if its GUID contains 'C<preview>', unless 'C<preview>' is also in the title of the item. The Australian Broadcasting Corporation RSS feeds occasionally include items whose GUIDS contain 'C<preview>' and link to non-existent pages, so this matcher was created to find them.

=head1 FUNCTIONS

=head2 match

    my $item_is_preview = App::Rssfilter::Match::AbcPreviews::match( $item );

Returns true if C<$item> contains 'C<preview>' in its GUID and not in its title.
