+version:                1.12.4
+x-revision: 1
+synopsis:               Generic programming library for generalised deriving.
+description:
+
+  This package provides functionality for generalising the deriving mechanism
+  in Haskell to arbitrary classes. It was first described in the paper:
+  .
+  *  /A generic deriving mechanism for Haskell/.
+     Jose Pedro Magalhaes, Atze Dijkstra, Johan Jeuring, and Andres Loeh.
+     Haskell'10.
+  .
+  The current implementation integrates with the new GHC Generics. See
+  <http://www.haskell.org/haskellwiki/GHC.Generics> for more information.
+  Template Haskell code is provided for supporting older GHCs.
