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
不需要什么详细的讲解，代码如下：
