-version:                1.12.1
-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.
