# for the package rather than rebuilding the modules of the package in
# a temporary directory. Haddock needs to build the package when it
# uses the Template Haskell or Annotations extensions, for example.
# Make the haddocking depend on the library .a file, to ensure
# that we wait until the library is fully built before we haddock it
