+    (description
+     "The OSQP (Operator Splitting Quadratic Program) solver is a numerical
+optimization package for solving convex quadratic programs.
+
+It uses a custom ADMM-based first-order method requiring only a single matrix
+factorization in the setup phase. All the other operations are extremely
+cheap. It also implements custom sparse linear algebra routines exploiting
+structures in the problem data.")
