尽管按照org-mode 官方 的说法，Org 是一个基于快速高效的文本方式来实现做笔记、管理待办事项（TODO list）以及做项目计划的模式（Org is a mode for keeping notes, maintaining TODO lists, and doing project planning with a fast and effective plain-text system ），但 Org-mode 首先是最好的文档编辑利器，没有之一。

My favorite scenes are (in this order) 1. The attack of the Rohirrim 2. Eowyn's fight with the witch king + this was already my favorite scene in the book + I really like Miranda Otto. Important actors in this film are: - Elijah Wood :: He plays Frodo - Sean Austin :: He plays Sam, Frodo's friend.

Angles are written as Greek letters \alpha, \beta and \gamma. The mass if the sun is M_sun = 1.989 x 10^30 kg. The radius of the sun is R_{sun} = 6.96 x 10^8 m. If$a^2=b$and$b=2$, then the solution must be either $a=+\sqrt{2}$or$a=-\sqrt{2}$. \begin{equation} x=\sqrt{b} \end{equation}
特殊设置之后，导出 HTML 时 LaTeX 代码片断会生成图片并包含进来。
导出
做好准备工作后，就可以导出了。使用命令：
1
C-c C-e
然后选择相应的格式，就可以导出对应的文件了。
发布
Org 包含一个发布管理系统，可以配置一个由相互链接的 Org 文件组成的工程项目的自动向 HTML 转换。你也可以设置 Org， 将导出的 HTML 页面和相应的附件如图片，源代码文件等自动上传到服务器。
