+This package comes "Batteries Included" with many useful lenses for the
+types commonly used from the Haskell Platform, and with tools for
+automatically generating lenses and isomorphisms for user-supplied data
+types.  The combinators in Control.Lens provide a highly generic toolbox
+for composing families of getters, folds, isomorphisms, traversals,
+setters and lenses and their indexed variants.
