C++ virtual machine version of nori.io

Mostly made to practice making a virtual machine.

There are no stability guarentees about the bytecode format.

Usage

nori build <file.nori>

Outputs into file.nr

nori run <file.nr>

Useful if you just want to experiment

nori exec
nori exec <file.nori>

If you don't pass a file to the command, it will read from standard input.

A fuller description of syntax and other things are available at nori.io and the wiki.
