copyless conversion between ByteString and Vector.Storable; profiling libraries

 This library allows conversion between the types from Data.ByteString
 Data.Vector.Storable without copying the underlying data. This is
 useful, for example, when ByteString IO produces or consumes vectors
 of numbers in native byte order.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
