Documentation of the CCK API

The primary sources are of course the d.o. handbook pages about CCK, the CCK Group on g.d.o., and the source code itself.

There are also a lot of blog pages all over the web, which I'm trying to gather here. I'm opening comments on this page so if you find any good page elsewhere, please add a comment about it so it can be added to that list.
