# Dependency notes:
# 1) Use a cunning trick for hashed-storage, haskeline, regex-compat
# where the min bound is the lowest version available.
# 2) Do the opposite for zlib: highest not available.
# 3) Prefer curl over HTTP since darcs uses an old version of HTTP.
# 4) Use the same bounds for mmap as hashed-storage.
