上一章我们好不容易创建好控制器，这里我们继续为magento创建模块配置文件，在app/code/local/Voodoo/News/etc下，我这里是app/code/local/Voodoo/

News/etc下创建一个config.xml文件：

<?xml version="1.0"?>
<config>
<modules>
	<Voodoo_News>

这个文件包含了我们的新闻模块的不同组成部分，既为前端和后台信息。如果我们观察该配置文件的结构，会发现有五个组件，

1.   (module)模块：它包含版本信息
2.   (frontend)前端：这包含路由器和布局信息
3.   (admin)管理员：这是路由器的设置和管理部分的参数
4.   (adminhtml)后台界面：这是菜单，ACL和布局管理
5。(global)全局：它包含配置的model, resources, blocks, and helpers等
