PR 18497. From http://www.twelf.org, heavily edited: Twelf is a research project concerned with the design, implementation, and application of logical frameworks. It provides a uniform meta-language for specifying, implementing, and proving properties of programming languages and logics. Example suites include Cartesian Closed Categories and lambda-calculus, the Church-Rosser theorem for the untyped lambda-calculus, Mini-ML including type preservation and compilation, cut elimination, theory of logic programming, and Hilbert's deduction theorem. The principal authors of Twelf are Frank Pfenning and Carsten Schuermann, with major contrubtions by Brigitte Pientka, Roberto Virga, and Kevin Watkins.
