# This package is needed to build dune.  To avoid circular dependencies, this
# package cannot depend on dune, or any package that depends on dune.
# Therefore, we:
# - hack up our own build, rather than using dune to do the build
# - bypass the need for ocaml-result (which requires dune to build)
# - skip tests, which require ppx_expect, which is built with dune
# - skip building documentation, which requires odoc, which is built with dune
# If you know what you are doing, build with dune anyway using this conditional.
