+  <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
