Support for commandline Golang project

Hello dear Gophers, I need some support for a medium sized command line tool written in Golang. Currently it has parameter handling like "gomando -help" but I need to change the library for parameter handling to have it Docker like "gomando help" or "gomando add data=eins" There will also be some other changes for it. This is NOT a fulltime project. I will give you small tasks like described above. Then I have to check it out, and there might be a week between single tasks. Tasks are usually small like for some hours, or 1-2 days. You can make suggestions to improve the tool. [login to view URL] [login to view URL]
