What I noticed about this - I'm not thrilled right now about using node to write console helper scripts, but the CLI lib they're using here does have a pretty nice interface. I do like Python generally for doing scripting type things, but there doesn't seem to be any mindshare for any cli helper libs for it other than click, which IMO has a really clumsy, awkward interface. Ruby is generally my favorite go-to now, and it has a bunch of cli helper libs with a variety of types of interfaces, at least some of which have what I consider to be a really slick interface.

If I was better at Python, I might try my hand at writing a better Python cli lib myself. I'm surprised nobody else has yet.
