[[exo-portal]] Configuration of portal and portlet skins

[<alotegi@xxxxxxxxx>]

Hi, 
I'm working on exo-portal (v2) and I don't find the way to use skins.
I know that in exo-portal v1.x, in an XML file (skin-config.xml) we define the
associations between portal components, renderers and CSS files that we call
styles. The page layout is a nested set of containers and portlets. Each
container has a renderer type that generates the markup language with the
correct CSS classes.
But in exo-portal v2 in the pages.xml file I don´t find the way to bind a
renderer type or decorator with pages, containers and portlets.
What is the way to bind that components(pages,containers and portlets) with 
CSS
files?

Can somebody help me, please?

Thanks,
