Say "Merry Christmas" 25 times counting down, using BER MetaOCaml to do staging.
Install OPAM if you don't already have it installed.
Switch to, or install, BER MetaOCaml:
If first time:
$ opam switch create 4.11.1+BER
Else:
$ opam switch 4.11.1+BER
Then
$ eval `opam config env`
If you don't already have ocamlbuild
installed:
$ opam install ocamlbuild
$ ocamlbuild -ocamlc metaocamlc src/main.byte
$ ./main.byte
Add a test.
