That’s indeed the idea, I just updated the Jenga repository to reflect that and the Dune’s readme. Currently Jenga offers a different feature set. It scales well to very large repositories, but on the other hand it doesn’t have rules to build OCaml projects in an classic open source environment such as with opam and it is less portable than Dune.
Initially, the plan was to have this Jenga bridge. We are still using Jenga inside Jane Street, however we are now planning to add what’s missing in Dune to replace Jenga and then completely switch to Dune.
