BFG is a Python web application framework based on WSGI. BFG is also referred to as repoze.bfg.
BFG shares version control facilities with the Repoze project, and is developed by the same primary developers, but its goals are different than the overall goals of the Repoze project. BFG is inspired by Zope, Pylons and Django. "Under the hood", BFG makes use of technologies from the Zope project.
