1890 of expression. So you should set 1 to second element. And the first
1891 matching group is sent to (image) processor defined by the variable

1895 ↑じゃ良くわかんないすね。例えば tgif hoge.obj して hoge.eps を
1896 \\epsfile{file=hoge.eps} でインクルードしているとしよう。その行で
1897 \[prefix\] g を押した時に tgif を起動して欲しかったら、まず上のような
1898 正規表現を設定する。\\\\(と\\\\)で囲んだところがファイル名になるように
1899 注意する。でファイル名部分が何番目の\\\\(\\\\)になるかをリストの2番目に書く。
1900 すると、その部分が変数 YaTeX-file-processor-alist で定義された
1901 処理プログラムに渡される。というわけ。
1902 ん〜やっぱりむずかしいね。分からない時は隣の Lisper に聞くか、
1903 fj野鳥の会で聞こう!
