Notes about intended audience
Due to the Python-centric nature of the ZODB, familiarity with Python will be assumed for this book. This means that we will have no sections on what is Python, Python's strenghts and installation.
At this point, I think it's also safe to assume that PyPi will be known to prospective ZODB developers, thus no easy_install explanation either.
The intended audience might be defined therefore as Python developers who are looking for an easy way to store their application's information.
