Video Tutorial on Setting up LabelMe with Ubuntu 12.04

I made a video tutorial for me and those who are not familiar with Apache configurations on Ubuntu.

Hope this helps.

It might be better if the authors could specify how to do the following two steps in detail, it took me a while to figure that out.
- Enable authconfig in Apache so that server side includes (SSI) will work. This will allow SVG drawing capabilities. This is the most common source of errors, so make sure this step is working.
- Allow perl/CGI scripts to run. This is the second most common source of errors.

首先查看链接的视频教程和现有的设置文档（如果有）。记录在 Ubuntu 12.04 上配置 Apache 以启用 SSI/authconfig 并允许运行 Perl/CGI 脚本的步骤；当面向新的 LabelMe 用户清楚地解释了两个常见的配置错误时，即视为完成。
