造了一个轮子，用于服务器更新和备份文件

用python 造了一个轮子：

1. 在服务器上自动拷贝文件到指定目录，在覆盖前自动备份旧的文件；
2. 这个脚本写得很简单只是检验文件是否一致，未做新旧文件的判断，如有其他需求请自行修改；
3. 同时备份发布文件到指定目录；
4. 发布完文件后自动删除发布目录；
5. 如要过滤发布文件的类型，请自行添加一行代码；

这个脚本需要一个配置文件，配置的格式如下:

 

[publish]

source=d:\update

target=d:\website

bakup=d:\backup

publish=d:\publish

	Maybe some bugs can not find  by local test,after u update new files ,u find it; At that time,u need recover the old files immediately.
	This script help u update the new files and backup the old files.
	This script can be use in many OS that support python.
	Before run this script,pls config the file :update.conf
