+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
+@url{http://hackage.haskell.org/package/vector}, a library with a
+similar intention.
+
+This library does not do advanced fusion optimization, since especially
+for lazy vectors this would either be incorrect or not applicable.  See
+@url{http://hackage.haskell.org/package/storablevector-streamfusion} for
+a library that provides fusion with lazy lists.")
