 Automatic Differentiation (AD) is a technique to analytically compute
 the derivative of a function at a given inner point of its domain.
 It overcomes the accuracy and efficiency problems related to the
 method of finite differences. This package implements the AD
 algorithms in Octave, a numerical computation software.
 .
 This Octave add-on package is part of the Octave-Forge project.
