  * Finish moving GenericPackageDescription into PackageDescription module
  and fix up remaing imports.
  hcOptions is back in the PackageDescription module but with a different type.
  GenericPackageDescription now derives Show as having the separate pretty
  printer is inconvenient and in any case it is incomplete.
