  * Add cabal fetch --no-deps and --dry-run flags
  Allows fetching one or more packages but without fetching their
  dependencies and thus not requiring that a consistent install plan
  can be found. On the other hand --no-deps means that there is no
  guarantee that the fetched packages can actually be installed.
