+"""This example illustrates the usage of creator, evaluator and generator.
+
+All the steps of airfoil creation & evaluation are detailed here;
+furthermore, the generator.py module contains certain presets
+(default airfoils).
+
+Create an airfoil;
+Evaluate an airfoil;
+Generate a population of airfoils & optimize.
