for a while now. It might be interesting to compare and contrast your tooling and git-hub - ingy's being straight bash, while a little crazy, makes installation really trivial, but then again yours supports multiple services, but then again who knows whether the different subcommand syntaxes will work better or worse for any particular other user.
(also, lest anybody think this is a veiled complaint, I'm sure ingy's reaction to finding your work exists will be "awesome, the more the merrier" followed by figuring out if you came up with any features he wants to steal ;)
