A web page consists of a base HTML document and any additional files it may include, such as stylesheets, scripts, images and fonts. We will refer to these additional files as assets. Assets are a very important part of the user experience. For today's rich, highly interactive web applications, the asset performance may be more significant than the backend application and database performance. In XOOPS 2.6.0 we'll use Assetic, developed by Kris Wallsmith, to manage all these assets.
