I don't know too much about purpose of has_info & is_dirty,
but when we store something into session for later use we have info.

I'd like to share an overview of Quixote.
Yesterday I generated some class diagrams starting from sources (UML
diagrams)
and today I played with Quixote and sessions.

I'd like to write in http://www.quixote.ca/qx/ some pages about Session,
Publisher, Directory, ...
about what is session and what do we expect from session object ...
