 > ファイル検出に問題がある

これは単に mknmzrc の $ALLOW_FILE で *.ps を検出させるようにすれば
いいだけでした。まだ text/plain と表示するけど、これでも良いのかな？

ついでに、dvi ファイルもテキスト抽出できるはずだとおもうのだけれど、
dviware はどれが良いのかさっぱりわかりません。しかも同じ名前でちょっ
とづつ違うものがいっぱい。他にもたくさんあるんでしょうがよくわから
んです。

  dvi2tty

  ftp://ftp.iis.u-tokyo.ac.jp/pub/TeX/CTAN/dviware/dvi2tty/
  ftp://contrib.redhat.com/pub/contrib/libc5/SRPMS/dvi2tty-5.1-1.src.rpm

  jdvi2tty
  http://www.geocities.co.jp/SiliconValley/7231/jdvi2tty.htm
  Nifty のものを勝手に転載したもの?

  dvi2text
  http://www.toc.lcs.mit.edu/~dmjones/dvi2text/
  Perl スクリプトで TeX::DVI::TXT, TeX::DVI::BYTE といったところを
  使っているらしい。試してない。


とりあえず、一番上の akiu の dvi2tty を持ってきて、同梱されている
日本語化パッチを当てて作ると jdvi2tty ができます。これと以下の
filter/dvi.pl で、なんとなくいけそうではあります。
