On the other hand, build systems come and go (and ./configure is like
the most horrible part to add logic to in most cases), while ocamlfind
has proved a reliable tool as a basis for any OCaml ecosystem so far.
If I can shelve some logic there without making the tool more complex
or less elegant I think that would be better for everyone.
