#  * PARALLEL_JOBS=N let ocamlbuild run N jobs in parallel. The recommended
#    value is the number of cores of your machine. Note that we don't want to
#    use make's own parallel flag (-j), as it will spawn several ocamlbuild jobs
#    competing with each other
#  * BUILD_FLAGS flags used to compile non production ocaml code (e.g tools,
#    tests ...)
#  * BUILD_PROD_FLAGS flags used to compile production ocaml code
