* 这个特性添加在svn trunk版本中，会在下一版本中发布出来。

大家在阅读Linux kernel内核代码时是否会觉得代码非常庞多？开源软件最不缺的就是源代码！同样RT-Thread也是这样，随着功能越来越多，代码也越来越庞大，为了解决这类问题，RT-Thread scons构建脚本加入新的命令行参数：scons --copy

调用这个参数命令后，可以把rt-thread目录中引用到的文件一分不少的复制一份到本地的rt-thread目录。这样能够非常方便学习、浏览代码。

另外需要注意的时，对于已有的bsp，需要支持这个特性，需要稍微修改下SConstruct文件：
```
# build program 
program = env.Program(TARGET, objs)

# end building 
EndBuilding(TARGET, program)
```

在EndBuilding的函数中加入前面返回的program变量。

例如对于ART的最小环境，执行scons --copy后会输出：
```

引用到RT-Thread中的文件被一个不少的复制到rt-thread目录中！
