My bad, I did not scroll down to see how complete the command set was. At the top of the readme the list of commands is misleading (I thought there were only those at the first read).
I'm not sure I can see a real use for checking out every repo of an organisation (I mean, if you do that with mozilla, you better start before going for a long holiday ), but having it /possible/ is a great thing
So I guess we're pretty much alike, git-repo being strong for being service agnostic, and git-hub being more complete.
Though, in my redesign plan I got for version 2, I have in mind a framework to make it possible to implement service-specific CLI API, while sharing a same core CLI API for the service-agnostic features.
So my hope is that people will like the tool enough to participate in the development and help make the tool more feature complete across the services!
