SpiderMonkey is the code-name for Mozilla Firefox's C++ implementation of
JavaScript. It is intended to be embedded in other applications
that provide host environments for JavaScript.

JavaScript is the Netscape-developed object scripting language used in millions
of web pages and server applications worldwide. Netscape's JavaScript is a
superset of the ECMA-262 Edition 3 (ECMAScript) standard scripting language,
with only mild differences from the published standard.

This package contains the JavaScript's library.
