因为一直没找到合适的命令行工具，所以自己实现了一个，很适合用来翻译外国命令行工具的自带帮助
（是的，就是用在 Batch-CN 第三方库的搜集整理上）
一年多前写的，用的是百度翻译api，实现了双语对照、全文翻译、参数控制等功能
但因为这个api有限制每月翻译字符数，共用难免会超，所以一直都未公开
现在把源码分享出来，基于 python3，另外需要大家自行注册api，修改【】符号所在位置的 appid 和 secretKey 即可使用
如需使用剪贴板相关功能，还需要 pyperclip 模块支持，请运行 pip3 install pyperclip 自行安装，不安装该模块也不影响其他功能的使用

PyInstaller py2exe之类打包出来，体积默认是20多M的吧？
不错哦。
