=head1 NAME

mtaws.pl - Movable Type Plugin to make "Book Spec" HTML Table with Amazon Webservices via SOAP.

=head1 SYNOPUS

<MTAwsAsin asin="B0000UX55W">

=head1 ABSTRACT

This script is tested under MT-2.661.
Please place this script {$MT-dir}/plugin/ .

At first, you should do followings to keep book spec cache and log.
$ mkdir {$CACHE_DIR}
$ chmod 744 {$CACHE_DIR}
$ chown www-data:www-data {$CACHE_DIR}

It is better to make StyleSheet.css with <div awsasin>.

このPluginはAmazon Web ServiceのSOAPインタフェースを使って本、DVD、CDなどの
紹介情報を取り込み、HTML Table形式で出力するものです。
MT-2.661でテストを行っています。

本スクリプトを {$MT-dir}/plugin/ディレクトリに置いて下さい。
また、上記ソース上の変数をご自分の環境に合わせて修正して下さい。

AWS経由で取得した情報はBerkley DB形式で{$CACHE_DIR}に置くので、
初期設定時に
mkdir {$CACHE_DIR}
chmod 744 {$CACHE_DIR}
chown www-data:www-data {$CACHE_DIR}
して下さい。

スタイルシートで<div awsasin>の設定をすると、美しく出るでしょう。
