' Bug良多，编写时候太急促，不到十个小时，没有按照层次来好好管理。
' 很多的功能也没有测试完。也无心去完善，现在唯一能做的就是加上对代码的释义
' 如果以后有人能帮忙完善。不胜感激！如果再能发给我完善的结果，那更是感恩泪涕：OnceATime@163.com

' LS的局限性，在这里表现的还是很明显的。如果留意观察，会发现我曾经绕的很麻烦。
' 错误的处理，其实这里已经有了很好的开始，或者说仅仅的一个思路，一个框架。
' 因为当时匆忙，肯定是没有多的时间放这里的了。
' LS的错误处理，其实未必比java的try机制弱到哪里去。我所讨厌的，仅仅是goto语句
'
' 中国的程序员，始终是在生存线上挣扎的
' 编程的快乐，，，，，，，在我有生之年只怕是没有希望了。
