python利用pysvn发布lib的小程序

背景：

本人在公司的平台部门工作，我们部门写出的代码都是编译成.a文件，定期发布版本到各个产品，现在老大要求我负责每周向公司的某个产品发布lib。发布lib的步骤大概就是自动化的兄弟给我提供一个归档的版本号、lib的标签号(对应我们平台的代码)和产品适配的标签号(对应产品代码，我们的.a文件会定期提交到这个svn下)，然后我根据这个信息，操作svn，定期把适配中指定标签下的指定的两个文件夹导出到归档目录下，然后在归档路径下创建记录这次发布信息(lib、适配各包含哪些标签、版本信息)的文档，还有就是创建一个release notes，要大家填写依赖。为了方便记录我还在另一个目录下记录着每次发布的信息。大概就是这样比较机械的操作，作为程序员当然不能甘于每周重复一次这样无趣的操作，于是乎利用今天调休的时间，用python写了个脚本代替这个工作。

主要用到的是python和pysvn(python)的一个第三方库。这里注意下pysvn要和对应版本的python使用才能生效，否则import会失败，所以建议先选pysvn，然后根据版本选python。
