For example the Jquery
jQuery UI
name: jqueryui
latest version: 1.8.12 (view older versions)
load request: google.load("jqueryui", "1.8.12");
extras: uncompressed:true (as in google.load("jqueryui", "1.8.12", {uncompressed:true});
path: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.12/jquery-ui.min.js
path(u): https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.12/jquery-ui.js
site: http://jquery.com/
note: This library depends on jquery. You must also load jquery before loading this module. Version 1.8.3 is not hosted due to its short life, and the alias 1.8.3 actually loads 1.8.4.
