/**
 * !#zh
 * 这里是一些用来判断执行环境的宏，这些宏都是全局变量，直接访问即可。<br>
 * 在项目构建时，这些宏将会被预处理并根据构建的平台剔除不需要的代码，例如
 *
 *     if (CC_DEBUG) {
 *         cc.log('debug');
 *     }
 *     else {
 *         cc.log('release');
 *     }
 *
 * 在构建后会只剩下
 *
 *     cc.log('release');
 *
 * （好棒棒）<br>
 * <br>
 * 如需判断脚本是否运行于指定平台，可以用如下表达式：
 *
 *     {
 *         "编辑器":  CC_EDITOR,
 *         "编辑器 或 预览":  CC_DEV,
 *         "编辑器 或 预览 或 构建调试":  CC_DEBUG,
 *         "网页预览":  CC_PREVIEW && !CC_JSB,
 *         "模拟器预览":  CC_PREVIEW && CC_JSB,
 *         "构建调试":  CC_BUILD && CC_DEBUG,
 *         "构建发行":  CC_BUILD && !CC_DEBUG,
 *     }
 *
 * !#en
 * Here are some of the macro used to determine the execution environment, these macros are global variables, can be accessed directly.<br>
 * When the project is built, these macros will be preprocessed and discard unreachable code based on the built platform, for example:
 *
 *     if (CC_DEBUG) {
 *         cc.log('debug');
 *     }
 *     else {
 *         cc.log('release');
 *     }
 *
 * After build will become:
 *
 *     cc.log('release');
 *
 * <br>
 * To determine whether the script is running on the specified platform, you can use the following expression:
 *
 *     {
 *         "editor":  CC_EDITOR,
 *         "editor or preview":  CC_DEV,
 *         "editor or preview or build in debug mode":  CC_DEBUG,
 *         "web preview":  CC_PREVIEW && !CC_JSB,
 *         "simulator preview":  CC_PREVIEW && CC_JSB,
 *         "build in debug mode":  CC_BUILD && CC_DEBUG,
 *         "build in release mode":  CC_BUILD && !CC_DEBUG,
 *     }
 *
 * @module GLOBAL-MACROS
