Tutorial-like documents

Hello,

I'm currently Xaraya-izing the web site of the NGO i'm working for.

I'd like to integrate documents to the article module, the way tutorials
are integrated in xaraya.com website. Meaning, i'd like to divide them
into various parts, having URL's like: articles/165?page=2

But i don't see the way to split documents in the 0.914 release. Did I
miss something in the documentation? How is that done?

Moreover, I'd like to have, for a particular category, or for a
particular publication type, an option to display directly the content
of a publication (instead of just the summaries) in the case when there
is ony *one* document in the category. Is there a way to do that? Where
do I have to put my nose if i want to code that kind of feature?

Cheers,
Benoit
