   9 - `haddock-project` handles sublibraries, test suites and benchmarks.
  10 - `haddock` receives `--package-name` flag whcih allows to set names of
  11   components which are included in the main `index.html` file.
  12 - added `--use-unicode` flag to `haddock` and `haddock-project` commands.
  13 - The directory structure of `./dist-newstyle` has changed.  `haddock`
  14   subcommand will install `package:sublib` component in a directory
  15   `package/sublib` under `l/sublib/doc/html/`.  This is important for
  16   `haddock-project` command and in the future might will be useful for hackage
  17   support of sublibraries.  See
