wheel部分有个小例子，代码不贴了。
其中有几行：
- # 告诉ReadLine监控终端
- $console->get( 'input your message,bye to quit: ');
- $heap->{console} = $console;
原以为$console->get仅仅是终端输出，所以在copy脚本的时候就删掉了。结果怎么调代码都不回显，server端也收不到东西。
cpan上关于这个get函数的说明：
get
get() causes POE::Wheel::ReadLine to display a prompt and then wait for input. Input is not noticed unless get() has enabled the wheel's internal I/O watcher.
After get() is called,the next line of input or exception on the console will trigger an InputEvent with the appropriate parameters. POE::Wheel::ReadLine will then enter an inactive state until get() is called again.
Calls to get() without an argument will preserve the current prompt. Calling get() with an argument before a whole line of input is received will change the prompt on the fly.
悲催啊。。。。。
