UserScripts are installable JavaScript. They are a cross-browser method of JavaScript injection.

UserScript support is widespread, but inconsistent - some browsers provide native support, while others require an extension. Different UserScript engines support different metadata keys, different security restrictions (eg cross-domain XHR), different global functions (`GM_*`).
