;; created 2008


;; .emacs就是一个程序,这意味着:
;; * 如果太大,就需要拆开,分成多个函数,甚至多个文件
;; * 它也要有自己的配置文件(将变动部分与不变部分分离)
;; * 需要进行版本控制


;; .emacs作为一个程序的目标:
;; * 跨平台(windows,linux,cygwin)
;; * 环境自适应(有什么包配什么包,不要配不存在的包而导致出错;用户可以启用或禁用某个包;用户可以选择用该包的哪个版本)
;; * 启动快速: 按需加载插件
;; * 易扩充,易维护


;; 本.emacs的功能汇总:
;; C-f8		insert key sequence
;; C-f7		(epm) compile current C++ file
;; f7		(epm) build project
;; f4		rebuild and reload BROWSE generated by ebrowse
;; f2		切换行间距大小


;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;  以下是实现部分  ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;; 为了加快启动速度,注释掉,需要时再通过C-x C-e执行吧
;; (require 'package)
;; (add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/") t)
;; (add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/"))

;; 确保在配置各个包之前先加载这些包
(setq package-enable-at-startup nil)
(package-initialize)

;; 程序主入口(main entry)在本文件最后


;; 一些外部包所在位置的默认值:
;; 可根据实际情况在~/.emacs.d/env.el中对这些位置进行调整(此文件在各个机子间不进行同步)。
;; 如果一个包的.el文件有自己独立的目录,就指向该目录;
;; 如果一个包的.el文件与其他包的.el文件共享同一个目录,则指向能表明该包存在的某个.el文件。
