Autosubst

Autosubst is a library for the Coq proof assistant which provides automation for formalizing syntactic theories with variable binders. Given an inductive definition of syntactic objects in de Bruijn representation augmented with binding annotations, Autosubst synthesizes the parallel substitution operation and automatically proves the basic lemmas about substitutions.
