+name:           typelits-witnesses
+version:        0.4.0.0
+synopsis:       Existential witnesses, singletons, and classes for operations on GHC TypeLits
+description:    This library contains:
+                .
+                *   A small specialized subset of the *singletons* library as it pertains to
+                    `Nat` and `Symbol`, for when you need some simple functionality without
+                    wanting to invoke the entire *singletons* library.
+                *   Operations for manipulating these singletons and `KnownNat` and
+                    `KnownSymbol` instances, such as addition and multiplication of
+                    singletons/`KnownNat` instances.
+                *   Operations for the comparison of `Nat`s in a way that works well with
+                    *GHC.TypeLits*'s different comparison systems.  This is helpful for
+                    bridging together libraries that use different systems; this functionality
+                    is not yet provided by *singletons*.
