对于Visual Studio的宏，大家应该很熟悉了，这是一篇关于JBuilder实现类似Visual Studio的宏扩展功能，我们就通过对一段代码是否注释掉作为简单例子。大家可以实现自己的一些扩展，算是抛玉引砖了。
支持环境： Jbuilder 4.0 - JBuilder 7.0
使用JBuilder编译时需要在 Project ---> Project Properties ---> Required Libaries中加上Jbuilder下的 Open Tool SDK，编译成功后将生成的class打包成一个JavaCommentSwitch.jar文件，其中包含这样一个文件META-INF\Manifest.mf，该文件内容如下：
Manifest-Version: 1.0
OpenTools-UI: JavaCommentSwitch
不需要什么具体的讲解，代码如下：
