The only other documentation I know of is in the book published by
Michael Neumann and co. (Ruby Developer's Guide, was it?).  However,
to answer your immediate questions:

- the session object can be accessed from any component as @session.
If you create a subclass of Iowa::Session it will be used instead of
the standard session class.  There's an example of this in the
guestbook example, which uses a session subclass to track the number
of hits.

- To create a new page, use the pageNamed method, passing it the name
of a component class.  This will return a new instance of that class,
which you can configure as you want; then yield it to have it be the
next page shown.  Again, there's an example of this in guestbook/, in
viewGuest of Main.html.
