+    """The Software for Linear Algebra Targeting Exascale (SLATE) project is
+    to provide fundamental dense linear algebra capabilities to the US
+    Department of Energy and to the high-performance computing (HPC) community
+    at large. To this end, SLATE will provide basic dense matrix operations
+    (e.g., matrix multiplication, rank-k update, triangular solve), linear
+    systems solvers, least square solvers, singular value and eigenvalue
+    solvers."""
