  GENIE is a suite of products for the experimental neutrino physics community.
This suite includes i) a modern software framework for implementing neutrino
event generators, a state-of-the-art comprehensive physics model and tools to
support neutrino interaction simulation for realistic experimental setups (the
Generator product), ii) extensive archives of neutrino, charged-lepton and
hadron scattering data and software to produce a comprehensive set of data/MC
comparisons (the Comparisons product), and iii) a generator tuning framework
and fitting applications (the Tuning product).
  This book provides the definite guide for the GENIE Generator: It presents
the software architecture and a detailed description of its physics model and
official tunes. In addition, it provides a rich set of data/MC comparisons that
characterise the physics performance of GENIE. Detailed step-by-step
instructions on how to install and configure the Generator, run its
applications and analyze its outputs are also included.
