-- | Interface to Amazon's Simple Storage Service (S3)
--   
--   This is the Haskell S3 library. It provides an interface to Amazon's
--   Simple Storage Service (S3), allowing Haskell developers to reliably
--   store and retrieve arbitrary amounts of data from anywhere on the
--   Internet.

-- | Add required headers for the storage class. Use this in combination
