========== Background ========== This version of the BFG wiki tutorial presents a :mod:`repoze.bfg` application that uses technologies which will be familiar to someone with :term:`Zope` experience. It uses :term:`ZODB` as a persistence mechanism and :term:`traversal` to map URLs to code. It can also be followed by people without any prior Python web framework experience. To code along with this tutorial, the developer will need a UNIX machine with development tools (Mac OS X with XCode, any Linux or BSD variant, etc) *or* he will need a Windows system of any kind. The tutorial makes mention of a CDROM disk. This is due to the fact that the tutorial is taught "live" under some circumstances. When it mentions use of a CD, there are alternate instructions which follow for people who do not have the CD. This tutorial is known to work under :mod:`repoze.bfg` version 0.9a7. Have fun!
