Rubinius : Use Ruby™
Author: Less Than Three. <3. http://less.thanthree.com
Description: Rubinius is an implementation of the Ruby programming language. The Rubinius bytecode virtual machine is written in C++. The bytecode compiler is written in pure Ruby. The vast majority of the core library is also written in Ruby, with some supporting primitives that interact with the VM directly.

### Roadmap

The Rubinius team is now focused on pushing Rubinius into the hands of all developers. To that end, the current highlevel roadmap goals for the next major release are:

- Microsoft Windows support
- Ruby 1.9 support
- Full CPU concurrency (hydra)

This roadmap is short on details about these because work on these elements has just begun. We'll update the roadmap as we formulate better what our approach is going to be.
