僕の script を野首さんの環境で動かすとどうですか?

試しました。(ファイル名を表示するようにしました)

です。wordはいいですけど、

  excel97.xls: application/powerpoint

はまずいですね。

ちなみに、 mknmz では

  % ./mknmz ../tests/data/ja
  (snip)

  15/15 - /home/satoru/cvs/namazu/tests/data/ja/word98.doc [application/msword]

と application/msword をきちんと認識します。どうやら
checktype_filehandle と checktype_filename の挙動がおかしい
(仕様?) ようです。

メイルに添付しました。
