教你自动下载文件并制作OpenBSD ISO

　　如果可能的话，请购买 OpenBSD 官方制作的 CD 套装。

　　详情请访问：http://www.openbsd.org/faq/faq3.html#BuyCD

　　脚本的使用方法：

　　$ ./mk_openbsd_iso-0.1.sh 3.9 i386

　　您只要指定需要制作的 OpenBSD 版本和平台架构，即可生成对应的 ISO 文件。

　　此脚本需要 wget / mkisofs 这两个工具才能制作ISO。

　　wget 用于下载文件，mkisofs 用于制作 ISO。

　　注意事项：

　　并不是每个平台都可以使用 CD 启动安装，详情请访问：

　　http://www.openbsd.org/faq/faq4.html#Overview

　　默认创建的 ISO 文件不会带有任何的 packages，如果你需要把 packages 包含进去，

　　请阅读脚本中函数 FETCH_PKGS() 的说明。

　　以下是完整的脚本：
