Copy dune-project and adjust names as desired

dune build at top level (generates {name}.opam)

opam install . --deps-only at top level (installs core dependency)

Subsequently, on terminal start run eval $(opam env) to bring installs into scope

For each day:

• create folder dayX
• copy dune file with entrypoint
• make {entrypoint}.ml in dayX folder
• dune build in dayX folder
• start developing in {entrypoint}.ml (hints will work in VSCode if you've installed the OCaml extension)
• run program with ocaml {entrypoint}.ml
  • NOTE: If using str library, need to explicitly link it by using ocaml str.cma {entrypoint}.ml
