+     "Fast, packed, strict storable arrays with a list interface, a chunky
+lazy list interface with variable chunk size and an interface for write
+access via the ST monad.  This is much like bytestring and binary but can be
+used for every @code{Foreign.Storable.Storable} type.  See also package with a
+similar intention at http://hackage.haskell.org/package/vector.
+
+We do not provide advanced fusion optimization, since especially for lazy
+vectors this would either be incorrect or not applicable.  However we provide
+fusion with lazy lists in the package
+http://hackage.haskell.org/package/storablevector-streamfusion.";)
