+      The fastNLO project provides computer code to create and evaluate fast
+      interpolation tables of pre-computed coefficients in perturbation theory
+      for observables in hadron-induced processes.
+
+      This allows fast theory predictions of these observables for arbitrary
+      parton distribution functions (of regular shape), renormalization or
+      factorization scale choices, and/or values of alpha_s(Mz) as e.g. needed
+      in PDF fits or in systematic studies. Very time consuming complete
+      recalculations are thus avoided.
