Well, I saw about hub, but I wasn't happy with the fact that it's a github only tool, I really wanted a service agnostic tool, and also because the CLI API was not great. I don't want a tool to replace git, I want it to extend it.
What git-repo really offers is a tool that integrates nicely to the git CLI (as `git-something` is also available as `git something`, so git-repo acts per default as `git repo hub…`). And then it autoconfigures the .gitconfig aliases to have the `git hub`, `git lab`, `git moo` you'd want.
So besides the fact that hub is certainly much more mature than my tool, it wouldn't be a tool I'd like to really use.
