A piece of Plone infrastructure that allows CSS/Javascript declarations to be contained in seperate, logical files before ultimately being appended to the existing Plone CSS/Javascript files on page delivery. Primarily enables Product authors to "register" new CSS/Javascript without needing to touch Plone's templates, but also allows for selective inclusion of CSS/Javascript files and reduces page load by minimizing individual calls to seperate blocks of CSS/Javascript files. Found in the ZMI under "portal_css" and "portal_javascript".
