 Nominal Isabelle is a definitional extension of the Isabelle/HOL theorem
 prover. It provides a proving infrastructure for convenient reasoning about
 programming language calculi. In this paper we present an extension of Nominal
-Isabelle for dealing with general binding structures. Such binding structures are
-ubiquitous in programming language research and only very poorly handled by
-single binding from the lambda-calculus. We give in this
-paper novel definitions for alpha-equivalence and establish automatically the
-reasoning structure for alpha-equated terms. For example we provide a strong
-induction principle that has the variable convention already built in.
