1、想写一个监视服务器是否运行的简单服务，网上搜到的例程不太完善，如梅劲松的许久没有更新，而且SvcDoRun写得不完整（见http://www.chinaunix.net/jh/55/558190.html，
不知道是不是原始出处）；而mail.python.org中的没有定义_svc_name_等变量（见
http://mail.python.org/pipermail/python-list/2005-December/315190.html）
2、这个实现功能很简单，就是把当前时间写入‘c:\\temp\\time.txt’文件，一看即知，大家可以随意扩充。
3、用
service install 安装
service start启动
service stop停止
service debug调试
service remove删除
service.py
