+      Espresso takes as input a two-level representation of a
+      two-valued (or multiple-valued) Boolean function, and produces a
+      minimal equivalent representation.  The algorithms used are new and
+      represent an advance in both speed and optimality of solution in
+      heuristic Boolean minimization.
