MuJS is a lightweight Javascript interpreter designed for embedding
in other software to extend them with scripting capabilities. It
is written in portable C and implements ECMAScript as specified by
ECMA-262.

Why? Because V8, SpiderMonkey and JavaScriptCore are all too big and
complex. MuJS's focus is on small size, correctness and simplicity.

The interface for binding with native code is designed to be as
simple as possible to use, and is similar to Lua. There is no need
for interacting with byzantine C++ template mechanisms, or worry
about marking and unmarking garbage collection roots, or wrestle with
obscure build systems.
