\begin{abstract} 

Nominal Isabelle is a definitional extension of the Isabelle/HOL theorem

prover. It provides a proving infrastructure for reasoning about

programming language calculi involving named bound variables (as

opposed to de-Bruijn indices). In this paper we present an extension of

Nominal Isabelle for dealing with general bindings, that means

term-constructors where multiple variables are bound at once. Such general

bindings are ubiquitous in programming language research and only very

poorly supported with single binders, such as lambda-abstractions. Our

extension includes new definitions of alpha-equivalence and establishes

automatically the reasoning infrastructure for alpha-equated terms. We

also prove strong induction principles that have the usual variable

convention already built in.
