convert ByteString<->Vector.Storable without copying; profiling libraries

 This library allows conversion between the types from Data.ByteString
 and 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.
 .
 The conversion relies on the fact that ByteString and Vector use their
 respective ForeignPtr's in compatible ways.
 .
 This library is a fork of spool.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
