+dsdp: Semidefinite programming solver
+=====================================
+
+Description
+-----------
+
+Implementation of an interior-point method for semidefinite
+programming. It provides primal and dual solutions, exploits low-rank
+structure and sparsity in the data, and has relatively low memory
+requirements for an interior-point method. It allows feasible and
+infeasible starting points and provides approximate certificates of
+infeasibility when no feasible solution exists. The dual-scaling
+algorithm implemented in this package has a convergence proof and
+worst-case polynomial complexity under mild assumptions on the data.
