haskell@gentoo.org Gentoo Haskell 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). Provide the Storage.Hashed.Diff module. Compile with the profiling ghc flag -fhpc.
