+               Provides Template Haskell functions that mimic deriving
+               extensions that were introduced or modified in recent versions
+               of GHC. Currently, the following extensions are covered:
+               
+               * @DeriveFoldable@
+               
+               * @DeriveFunctor@
+               
+               * @DeriveTraversable@
+               
+               The following changes have been backported:
+               
+               * In GHC 8.0, @DeriveFoldable@ was changed to allow folding
+               over data types with existential constraints.
+               
+               * In GHC 8.0, @DeriveFoldable@ and @DeriveTraversable@ were
+               changed so as not to generate superfluous @mempty@ or @pure@
+               expressions in generated code. As a result, this allows
+               deriving @Traversable@ instances for datatypes with unlifted
+               argument types.
+               
+               * In GHC 8.0, deriving @Show@ was changed so that constructor fields
+               with unlifted types are no longer shown with parentheses, and
+               the output of showing an unlifted type is suffixed with the same
+               number of hash signs as the corresponding primitive literals.
+               
+               * In GHC 8.2, deriving `Ord` was changed so that it generates concrete
+               @if@-expressions that are not subject to @RebindableSyntax@.
+               
+               Note that some recent GHC extensions are not covered by this package:
+               
+               * @DeriveGeneric@, which was introducted in GHC 7.2 for deriving
+               @Generic@ instances, and modified in GHC 7.6 to allow derivation
+               of @Generic1@ instances. Use @Generics.Deriving.TH@ from
+               @&lt;http://hackage.haskell.org/package/generic-deriving generic-deriving&gt;@
+               to derive @Generic(1)@ using Template Haskell.
+               
+               * @DeriveLift@, which was introduced in GHC 8.0 for deriving
+               @Lift@ instances. Use @Language.Haskell.TH.Lift@ from
+               @&lt;http://hackage.haskell.org/package/th-lift th-lift&gt;@
+               to derive @Lift@ using Template Haskell.
