CppAD is a package for automatic differentiation (AD) of algorithms
written in C++. Given appropriately written C++ code that computes a
function, CppAD augments it to also compute derivative values. The
system uses templates, supports forward and reverse accumulation
modes, and allows nested derivatives.
