EXTjs 文件压缩

之前曾使用过的办法有gzip（我记性不是很好，就是放在IIS中用以压缩页面代码的工具，具体名字记得不是很清楚，如果您比较清楚，请指正，互相学习）、和YUIcompressor等压缩js代码工具。



请进这个页面 http://mootools.net/download 下载那个 YUI Compressor 了吗,才65K 下来后发现 文件夹里面：

build-+

      -yuicompressor-2.4.2.jar

doc--+

      -CHANGELOG -README

lib--+

      -jargs-1.0.jar

      -rhino-1.6R7.jar

src--+

      -com--+

           - ...

      -org--+

            -...

ant.properties

build.xml

再看看build.xml里面写了些什么：

<?xml version="1.0" encoding="iso-8859-1"?>
