Bug#532154: RFP: haskell-hashed-storage -- hashed file storage support code

["Trent W. Buck" <trentbuck@gmail.com>]

Package: wnpp
Severity: wishlist

This package is a build dependency for the next version of Darcs.
Thus, this needs to be in Debian before Darcs 2.3 can enter Debian.
If nobody else wants to take this one, I will.

  Description     : hashed file storage support code

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).
