+    """SPGL1 is a solver for large-scale one-norm regularized least squares.  It is
+       designed to solve any of the following three problems: Basis pursuit denoise
+       (BPDN): minimize ||x||_1 subject to ||Ax - b||_2 <= sigma, Basis pursuit (BP):
+       minimize ||x||_1 subject to Ax = b Lasso: minimize ||Ax - b||_2 subject to
+       ||x||_1 <= tau, The matrix A can be defined explicitly, or as an operator that
+       returns both both Ax and A'b.  SPGL1 can solve these three problems in both
+       the real and complex domains."""
