OCaml beta compilers

This is an opam repository that contains beta releases of the OCaml compiler. It is in a separate opam remote from the stable opam-repository so that the beta compilers are an opt-in for advanced users.

To activate this repository in your current opam switch:

opam repo add beta https://github.com/ocaml/ocaml-beta-repository.git

This will add the beta remote as a non-default extra source of opam packages. You can then create a compiler switch to the trunk compiler by:

opam switch create 408 ocaml-variants.4.08.0+trunk --repositories=default,beta

This will create the 408 switch and make the opam packages from the default opam repository available, but compiled with the beta version of the compiler.
