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
