Learning to use the Drom build system for ocam/reasonml projects.
It took nothing at all to compile with reason. Apparently, drom is aware of reason syntax files. This is a really nice addition to the options for building with reason/ocaml and might be my go to option to start a project. Thanks to the folks at OCamlPro.
