+description: """
+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."""
