使用auto-complete-mode

	使用auto-complete-mode
	1 下载auto-complete完整源码
	大多数情况下，我还是推荐使用源码库中的最新版本，这样可以避免很多奇怪的问题。所以这里列出了使用auto-complete-mode所涉及的一些源码库：
	auto-complete-mode 主源码库
	https://github.com/m2ym/auto-complete.git
	popup功能库
	https://github.com/m2ym/popup-el.git
	使用fuzzy模式匹配
	https://github.com/m2ym/fuzzy-el.git
	增强列表模式
