+    """CaNS (Canonical Navier-Stokes) is a code for
+    massively-parallel numerical simulations of fluid
+    flows. It aims at solving any fluid flow of an
+    incompressible, Newtonian fluid that can benefit
+    from a FFT-based solver for the second-order
+    finite-difference Poisson equation
+    in a 3D Cartesian grid."""
