oo.WebsiteTools is a set of basic tools which are needed on almost every Web site. Using these tools speeds up your Web development radically. It consists of three different parts: oo.Admin, oo.Sql, and oo.Ajax. oo.Admin is used to administer the site and allow users to manage their accounts. oo.Sql lets you change database backends without changing your SQL code. oo.Ajax is an AJAX library that can load and update div elements, send forms without reloading the page, and more.
