> what does dune actually offer me if I’m using Nix to manage dependencies already?

purs-nix is a good example that even if per-module compilation is made into derivations, the rest of the remaining heavy-lifting of constraints resolution is done by the external build tool. You can think of Nix as a dependency manager, but only with a huge caveat that it doesn't actually manage constraints that come with those dependencies, especially transitive ones.

That's a good read but I'm still unclear on dune vs. ocamlfind/ocamlopt. Is dune not using those under the covers like Nix could?
