Cydia源目录结构解析

在Cydia添加一个第三方源之后，会做如下事情(以xcon.crazy.net为例)：

• 访问http://xcon.crazy.net/./Release.gpg
• 访问http://xcon.crazy.net/./zh_CN.bz2
• 访问http://xcon.crazy.net/./Release
• 访问http://xcon.crazy.net/./Packages.bz2
• 访问http://xcon.crazy.net/./CydiaIcon.png

其中bz2内打包了软件列表

后面如果从cydia安装xcon就直接访问：
http://xcon.crazy.net/Files//V39/com.n00neimp0rtant.xcon_39~beta5_iphoneos-arm.deb

dpkg -X xcon.deb xcon/
