使い方。

1. ライブラリTarzanをhttp://tarzan-aws.com/　からDLしてパスが通っている場所、もしくは下記プラグインファイルと同じ場所に配置。
2. 順番前後しますが、Tazan内の　config.inc.php　にアマゾンの認証キー等を設定。ほんとはプラグインの管理画面から設定できるのがベストなんだろうな。
3. 投稿のアマゾンの商品情報を展開したい部分にショートコードを　［amazonitem type=”商品タイプ”］ASIN［/amazonitem］ と記述

以上。過去記事との互換性のためにショートコードがtmkm-amazonでも動作するようにしてあります。ほんとはXSLTとか使った方がスマートなんだろうけどね。現状、音楽CDの場合には収録曲が表示されます。
