+general-purpose unconstrained non-linear optimization.  The algorithm is of
+quasi-Newton type with BFGS updating of the inverse Hessian and soft line
+search with a trust region type monitoring of the input to the line search
+algorithm.  The interface of @code{ucminf} is designed for easy interchange
+with the package @code{optim}.")
