efficient cryptographic hash implementations bytestrings; profiling libraries

 This package provides efficient cryptographic hash implementations for strict
 and lazy bytestrings. For now, CRC32 and Adler32 are supported; they are
 implemented as FFI bindings to efficient code from zlib.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
