+    """MOAB is a component for representing and evaluating mesh
+    data. MOAB can store structured and unstructured mesh, consisting
+    of elements in the finite element 'zoo.' The functional interface
+    to MOAB is simple yet powerful, allowing the representation of
+    many types of metadata commonly found on the mesh. MOAB is
+    optimized for efficiency in space and time, based on access to
+    mesh in chunks rather than through individual entities, while also
+    versatile enough to support individual entity access."""
