After that, I suggest we merge the @blobfish work related to the move to occ-691. @QbProg and I suggested to use the Denis' approach to apply oce changes to occ codebase, but we actually never did the job, and I don't plan to do it in a short time. So, so far, @blobfish PR
https://github.com/tpaviot/oce/pull/589 is the best and only candidate for a support of occ691, I guess it requires some updates before being merged into the master branch, but let's be pragmatic and use what we have.
