+ (description "Formalizing syntactic theories with variable binders is
+not easy. Autosubst is a library for the Coq proof assistant to
+automate this process. 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. This library contains an automation
+tactic that solves equations involving terms and substitutions. This makes the
+usage of substitution lemmas unnecessary. The tactic is based on our current
+work on a decision procedure for the equational theory of an extension of the
+sigma-calculus by Abadi et al. The library is completely written in Coq and
+uses Ltac to synthesize the substitution operation.")
