我不是大神，使用vim和emacs只是兴趣，打发空闲时间。

然后看下(这头牛真不错)：
emacs开发网站
Main repository:
git clone -b master git://git.sv.gnu.org/emacs.git
ELPA repository:
git clone git://git.sv.gnu.org/emacs/elpa
官方文档在这里emacs开发配置，还是需要硬读英文文档。
最新更新：
(setq package-archives '(("gnu" . "http://elpa.emacs-china.org/gnu/")
("melpa" . "http://elpa.emacs-china.org/melpa/")))
