To put it differently: with page templates you try to separate concerns,
by splitting things into: content, presentation, portlets, viewlets,
macros, local variations in the presentation.... (put your concept here)
using the TAL language. But what you start from is in fact a HTML page.

In cpsskins you start from the individual concepts (portlets, widgets,
styles, slots, pages, themes, perspectives. ...) that can be related in
different ways and the job of the rendering engine is create a
particular composition based on the instructions given by different
categories of users (UI designers. site designer, application designers,
users, .. )
