Emacsのelispインストール・設定・使い方

el-getとは，Emacsに外部のスクリプトや拡張をダウンロードしインストールしてくれる

ツールです．

もし，el-getをインストールしていない場合は，次のコードを初期設定ファイル(.emacs等)に

書き，Emacsを再起動するか’M-x load-file’で初期設定ファイルを読み込んでください．

自動的にel-getがインストールされます．

(add-to-list 'load-path "~/.emacs.d/el-get/el-get")

(unless (require 'el-get nil t)
  (url-retrieve
   "https://github.com/dimitri/el-get/raw/master/el-get-install.el"
   (lambda (s)
     (end-of-buffer)
     (eval-print-last-sexp))))

;; now either el-get is `require'd already, or have been `load'ed by the
;; el-get installer.

このコードの後半にもありますが，cvsとsubversionがシステムにインストール

されていることが前提です．

Debianでは，次のコマンドでインストールできます．

apt-get install cvs subversion

ミニバッファで’M-x el-get-install wanderlust’と打つと

Wanderlustだけでなく依存関係にあるapel,flim,semiも

インストールされます．
