This document reports on recent advances in the development of the adjoint
code generator OpenAD/F. We give an overview of the software design, and
we discuss case studies that illustrate the feasibility of adjoint code
generation.  Our main target application is the MIT General Circulation
Model --- a numerical model designed for study of the atmosphere, ocean,
and climate.
