This project is the current reference implementation of Mu, the micro virtual
machine designed by [The Micro Virtual Machine Project](http://microvm.org).
Version 2.1.x implements the latest revision of the [Mu Specification version
2](https://github.com/microvm/microvm-spec/wiki).
Version 2.1.x implements the [goto-with-value form of the Mu
Specification](https://github.com/microvm/microvm-spec/tree/goto-with-values),
which will eventually become the main line.
This project is based on the previous works of
