Rv, a new kind of Ruby management tool

One thing I love about Ruby is it never devolved into ?VM hell like Python did. Yes, there are a bunch of ruby version managers, but there's only one bundler no matter how you get get ruby installed. I like some ideas here, but I'm also afraid this could be step one toward that python nightmare.

It seems pretty different in that rv waited to take inspiration from a relatively clear winner in an entirely different ecosystem, after quite some time. I think it makes sense to be optimistic.
