  <longdescription lang="en">
  Ceres Solver is a portable C++ library that allows for
  modeling and solving large complicated nonlinear least squares
  problems. It features:
    * automatic differentiation
    * robust loss functions
    * local parameterizations
    * threaded Jacobian evaluators and linear solvers
    * Levenberg-Marquardt and Dogleg (Powell, Subspace) solvers
    * Dense QR and Cholesky factorization (using Eigen) for small problems
    * Sparse Cholesky factorization (using SuiteSparse) for large sparse
      problems
    * Specialized solvers for bundle adjustment problems in computer vision
    * Iterative linear solvers for general sparse and bundle
      adjustment problems
