* 2001.1.24 - 初版
*
* 使い方： INSPECT 入力ファイル名
*
* Macintosh を使っている友人から送られてきた添付ファイルが開けない
* 経験はありませんか。Macintosh は Windows と違い、ファイルに拡張
* 子をつける必要がありません。そのため、そのデータがどのような形式
* であるのかを拡張子のみで判断している Windows では解釈できないの
* です。たとえば、OutLook Express などのメールソフトで受信した時、
* 次のようなファイルが添付されていることはありませんか？
*
* %xxxxxxxx (nnn バイト)
* xxxxxxxx (mmm KB)
*
* これは、AppleDouble と呼ばれる形式で、２つでひとつのファイルを表
* しています。Windows で必要なのは下のファイルのみですが、そのファ
* イルに関するさまざまな情報が上のファイルに入っています。
* この頭に % のついたファイルを INSPECT.EXE にドラッグ＆ドロップす
* るとファイルの様々な情報とともに、Macintosh 特有のファイルタイプ
* とクリエーターと呼ばれる識別子を読み取り、このデータを作成したア
* プリケーションとデータの形式、および、拡張子を推測します。
* 拡張子がわかれば、下のファイルにその拡張子を付けて保存して、該当
* するアプリケーションがインストールされている環境であれば開くこと
* が出来るようになります（該当するアプリケーションがない場合は開け
* ません）。また、拡張子が分からない場合でも、アプリケーションから
* 直接開くことが出来ます。
