-- Module : Data.Memory.Internal.DeepSeq
-- License : BSD-style
-- Maintainer : Vincent Hanquez <vincent@snarc.org>
-- Stability : experimental
-- Portability : unknown
--
-- Simple abstraction module to allow compilation without deepseq
-- by defining our own NFData class if not compiling with deepseq
-- support.
