The tutorial on the werkzeug web site http://werkzeug.pocoo.org is
pretty nice - it combines the werkzeug wsgi libraries/framework with
SQLAlchemy and jinja (the Django template language).  The result is in
my opinion a nice simple framework that is easier and cleaner than
Django and cleaner than webpy   the view file in the tutorial just needs
simple functions like "def index(request)" not the class index  def GET
... .   Their web site is run by this werkzeug/SqlAlchemy/jinja
combination - seems pretty good.  This could be the real sweet spot
python framework if I'm seeing it right.
