+    (description "This project contains an extended \"Standard Library\" for
+Coq called coq-std++.  The key features are:
+@itemize
+@item Great number of definitions and lemmas for common data structures such
+as lists, finite maps, finite sets, and finite multisets.
+
+@item Type classes for common notations (like ∅, ∪, and Haskell-style monad
+notations) so that these can be overloaded for different data structures.
+
+@item It uses type classes to keep track of common properties of types, like
+it having decidable equality or being countable or finite.
+
+@item Most data structures are represented in canonical ways so that Leibniz
+equality can be used as much as possible (for example, for maps we have m1 =
+m2 iff ∀ i, m1 !! i = m2 !! i).  On top of that, the library provides setoid
+instances for most types and operations.
+
+@item Various tactics for common tasks, like an ssreflect inspired done tactic
+for finishing trivial goals, a simple breadth-first solver naive_solver, an
+equality simplifier simplify_eq, a solver solve_proper for proving
+compatibility of functions with respect to relations, and a solver set_solver
+for goals involving set operations.
+
+@item The library is dependency- and axiom-free.
