2008年的时候，在vmware中开始学习ubuntu。
什么都不会，安装软件基本上是google以后apt-get。
后来ubuntu有了software center，就直接装。
于是乎问题来了。
ubuntu维护的软件版本有时候会赶不上开发者的进度。
emacs就是一个例子。
cedet1.0pre4和emacs2.32就出现无法jump的问题。
但cedet1.0正式版就可以正常jump。
去年学习emacs，每次换环境，都要在synaptic package manager中勾选cedet等，然后ubuntu自动安装到相关目录。
因为插件多，感觉比较麻烦。
后来发现用户目录下也有.emacs.d的文件夹，里面也可以存放插件的文件。
因此emacs的迁移就简单了。
首先从sourceforge下载需要的插件，自然都是最新的。
cedet：http://cedet.sourceforge.net/
ecb：http://ecb.sourceforge.net
doxymacs：http://doxymacs.sourceforge.net
xcscope: http://cscope.sourceforge.net
或者还有自己收集的插件等。
解压到用户目录的.emacs.d目录中。
然后在用户目录的.emacs文件中指向.emacs.d目录即可。
以后只要ubunut下安装emacs即可。复制.emacs文件,.emacs.d目录到用户目录下即可。
善意的提示：在ubuntu下启动桌面特效的话，启动过程可能无法正确设置最大化窗口。
顺便贴一份我的配置：
