The focused notion of correctness for program transformations is invariance with respect to the observational semantics of programs. The so-called diagram method is automated by combining unification, matching, and reasoning on alpha-renamings on the higher-order meta-language, and automating induction proofs via an encoding into termination problems of term rewrite systems. We explain the techniques, we illustrate the usage of the tool, and we report on experiments. Keyphrases: contextual equivalence, correctness, deduction, observational equivalence, program transformation, semantics, verification
