    　Emacsを使い始めて、段々とその便利さがわかってきた。現在はLaTeXで修論を書いているのですが、LaTeXの打ち込みとコンパイルまでを一括して処理してくれています。
</p>
  
<p>
    　そんな感じで便利さを体感していると、なんと<a href="http://www.tsdh.de/cgi-bin/wiki.pl/doc-view.el" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://www.tsdh.de/cgi-bin/wiki.pl/doc-view.el', 'EmacsでPDFを閲覧できる');" target="blank">EmacsでPDFを閲覧できる</a>ことを知りました。使ってみると、Windowsでは使えない文字で作業用ファイルを書き込もうとしていて、PDFが閲覧できませんでした(..;)どうにかならんのかと検索していたら、すでに他の人も作者の人に指摘済みでした（→<a href="http://www.mail-archive.com/gnu-emacs-sources@gnu.org/msg01114.html" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://www.mail-archive.com/gnu-emacs-sources@gnu.org/msg01114.html', 'doc-view.el &#8212; View PDF/PostStript/DVI files in Emacs');" target="blank">doc-view.el &#8212; View PDF/PostStript/DVI files in Emacs</a>）:

      Maybe use `temporary-file-directory&#8217; or `make-temp-name&#8217;.

      Probably not portable, I think.&#160; Windows users may set the directory<br />to &#8220;c: ooar&#8221;.&#160; Maybe you could do like the package formerly knows<br />as `tumme.el&#8217; does it.&#160; Ah, it&#8217;s `image-dired.el&#8217; now:<br />`image-dired-thumb-name&#8217;.

    　というわけで、もう一度elispを導入してみようと思う。
