Python基础学习：svn导出差异文件脚本
由于是刚接触python不久，所以很多都不是很熟练，只能是用到什么查点什么。所以如果有什么bug或者不严谨的语法或其他，希望各位看客指正。
鉴于公司的平台研发部门需求想直接把svn中的差异代码导出并打包自动上传到指定的服务器上，然后在从指定的服务器上进行一个发布更新。由于我们开发和发布服务器的环境很特殊，中间牵扯到很多网络代理。所以才这么麻烦。
要求如下：
1、自动导出指定版本之间的差异文件
2、根据给定的选项过滤出指定的文件夹以及文件；例如给定选项 a ,那就导出的文件中只保留admin的内容
3、自动打包这些内容并按照当前的时间命名
4、以FTP模式上传到指定的服务器
主要还是在windows下操作这些，实在想不出什么好的方法，于是网络搜索求助。网络真是个神奇的东西，当然我还是没有搜到任何结果。于是加了一些脚本的群，随机的找一个管理员问下有没有相关的脚本或思路。真是天无绝人之路。第一个请教的哥们就给了我一个回答。python可以搞定(当然给的指导肯定不止这些)。
于是当下又在学习python，顺便就用这个来实现(其实是不知道用什么来操作的)
在多次google、baidu之后。就写了以下的脚本，目前测试是能满足基本需求的：
python的环境需求：py32-pysvn, python-3.2
pysvn下载官网：http://pysvn.tigris.org/
python的官网就不用提供了吧。
