# Special note for devs looking to upgrade this package:
#   ghc places a unique hash for each library when it is built.
#   Libraries depend on versions specified by those hashes.
#   This implies that all libraries need to be rebuilt when ghc is rebuilt.
#   Also, due to dependency loop problems, haskell-ghc-paths and haddock
#   do not carry version dependencies. You will have to remember to build them too.
