interpreter/Makefile

# This Makefile uses dune but does not rely on ocamlfind or the Opam
# package manager to build. However, Opam package management is available
# optionally through the install target.
#
# The $(JSLIB).js target requires Js_of_ocaml (using ocamlfind).
#
# See README.me for instructions.
