指定アプリケーションのバイナリアーキテクチャ判定

指定のアプリケーションファイルが32bitバイナリかどうかを判定するAppleScriptです。

実行ファイルのパスを求めて、fileコマンドで情報を取得します。本Scriptでは32bitバイナリであるかどうかの判定のみ行なっていますが、CPUアーキテクチャに着目してPPC/Intel 32/Intel 64/ARMの判定を行えるように作り込めます。

また、アプリケーションでありながらもバンドル形式になっていない実行ファイル（古い時代のファイルだったり、サードパーティの開発環境だったり）も存在しているため、NSBundleを求めたときにmissing valueが返ってくることもあります。

１ファイルだけ処理できてもあまり意味がないので、指定フォルダ以下のすべてのアプリケーションファイルをリストアップして、ループで処理するようなことをやることになるでしょう。
