序
今天同事让我写一个停止自己工程的脚本. 写了一会，他说发现已经有这个脚本了，不跟我玩了。 回来自己将这个实验做完。 测试程序：根据退出标记文件，进行安全退出。 脚本：先做出退出标记文件，睡眠，如果程序还不退出，杀掉。

@note
# 必须在Makefile目录下新建至少一个子目录!, 否则产生的SUBOBJ和ROOTOBJ有重名，导致编译失败
# 为了不建立无意义的文件夹(e.g. 只有一个主文件main.cpp), 在Makefile统计目录建立一个文件夹main
# 将主文件main.cpp放到main中，就可以编译过了
#
# 从博客上回帖的Makefile内容，每行前面的\t都变成空格了，bash不认，杯具啊
