Introducing rv: A Comprehensive Ruby Version and Dependency Management Tool

For the last ten years or so of working on Bundler, I've had a wish rattling around: I want a better dependency manager.

It doesn't just manage your gems, it manages your ruby versions, too.

It installs pre-compiled rubies so you don't have to wait for ruby to compile from source every time.

It makes it completely trivial to run any script or tool written in ruby, even if that script or tool needs a different ruby than your application does.
