 \begin{abstract}
-  \noindent This tutorial gives an introduction to a generic code generator framework in Isabelle
-  for generating executable code in functional programming languages from logical
-  specifications in Isabelle/HOL.
+  \noindent This tutorial introduces the code generator facilities of Isabelle/HOL.
+    They empower the user to turn HOL specifications into corresponding executable
+    programs in the languages SML, OCaml and Haskell.
