I've put up a screencast describing application development under repoze.bfg using a lame Wiki theme (forgive me for being so 2003). It's roughly twenty minutes or so long, and it covers the basics of app development under bfg. repoze.bfg is a web application development platform inspired by the Zope publisher, although it's development flow is perhaps more like Pylons than it is like Zope. I hold forth about that in the screencast, so watch. ;-)
