Nutch-0.9中，org.apache.nutch.crawl.Crawl类中提供了一个入口主函数main，通过接收键入的命令行，根据命令行指定的参数对Nutch进行配置，从而启动Nutch抓取程序，通过阅读org.apache.nutch.crawl.Crawl类的源代码来了解Nutch是如何根据接收的命令行进行配置及其启动的。
org.apache.nutch.crawl.Crawl类的主函数如下所示：

最近正在研究extjs，可以访问http://www.extjs.com
FAQ http://extjs.com/learn/Ext_FAQ
看了Demo以后简直是无法收拾了，从速度还有效果来看ajax.asp.net没有办法比了。
学习之前还是强烈推荐一下javascript 面向对象支持
另外这里还涉及到一些prototype的概念，可以参考Prototype.js深入学习的帖子，感觉还不错
PS一下，Ext js 有很多资源的索引 http://extjs.com/learn/Manual:Resources#OO_JavaScript

1. 执行 以下语句 安装scaffolding
ruby script/plugin install scaffolding
2. 分页插件的解决方法
状况如下：
undefined method `paginate’
解决办法：安装老的classic_pag ...
