libghc-hashed-storage-prof 0.5.11-3build1 (amd64 binary) in ubuntu wily

 Support code for reading and manipulating hashed file storage (where each file
 and directory is associated with a cryptographic hash, for
 corruption-resistant storage and fast comparisons).
 .
 The supported storage formats include darcs hashed pristine, a plain
 filesystem tree and an indexed plain tree (where the index maintains hashes of
 the plain files and directories).
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
