rbenv - A Simple Ruby Version Manager

rbenv is a new kid on the block! A simplistic ruby version manger which manages ruby versions and lets you switch between different versions easily and that's it.

Unlike rvm, it does not,

• Have a configuration file - well there is nothing to configure other than ruby version
• Install Ruby - you are on your own
• Manage gemsets - Bundler is your buddy

It's good to have no frills version manager, but if you like rvm, don't switch to rbenv! You will surely miss rvm.
