Thank you for the feedback! v2 of patch series coming shortly...

I was not aware of the `ocaml4.07-variant` property. It makes 
things a
lot nicer!

I've added it for `ocaml-markup` and `ocaml-odoc` and also
`ocaml-sexplib0`, `ocaml-parsexp`, `ocaml-base` and 
`ocaml-sexplib`.

This makes `ocaml4.07-*` vanish from lot of places in favor of
`(package-with-ocaml4.07 *)`.

Not yet. For ocaml-markup 1.0.0 the problem is that the dune file
version is set to 2.7. Any dune below 2.7.x will probably not 
work.

For other packages it might work...

\o/ Looking forward to the bootstrap!

With the `ocaml4.*-variant` property managing the 3 trees does not 
seem
so bad after all.

Currently there are a lot of packages only for 4.07. It would be 
nicer
to have packages for default compiler and when needed variants for 
older
compilers.

I plan to do some OCaml hacking in the next months and will send 
in
patches toward this, if that is ok.

Done. Patch 13 in v2.
