This options allows to easily extend a shell with an OCAMLPATH suitable for building F* OCaml programs, and also to simply run a build command easily by prepending `fstar.exe --ocamlenv` to it. Example below. Hello.fst: module Hello open FStar.IO let _ = print_string "Hello F*!\n" $ fstar.exe --ocamlenv OCAMLPATH='/home/guido/r/fstar/master/lib:'; export OCAMLPATH; $ fstar.exe --ocamlenv ocamlfind ocamlopt -linkpkg -package fstar.lib Hello.ml findlib: [WARNING] Interface ratio.cmi occurs in several directories: /home/guido/.opam/4.14.1/lib/num, /home/guido/.opam/4.14.1/lib/ocaml findlib: [WARNING] Interface num.cmi occurs in several directories: /home/guido/.opam/4.14.1/lib/num, /home/guido/.opam/4.14.1/lib/ocaml findlib: [WARNING] Interface topdirs.cmi occurs in several directories: /home/guido/.opam/4.14.1/lib/ocaml/compiler-libs, /home/guido/.opam/4.14.1/lib/ocaml findlib: [WARNING] Interface big_int.cmi occurs in several directories: /home/guido/.opam/4.14.1/lib/num, /home/guido/.opam/4.14.1/lib/ocaml findlib: [WARNING] Interface nat.cmi occurs in several directories: /home/guido/.opam/4.14.1/lib/num, /home/guido/.opam/4.14.1/lib/ocaml findlib: [WARNING] Interface arith_status.cmi occurs in several directories: /home/guido/.opam/4.14.1/lib/num, /home/guido/.opam/4.14.1/lib/ocaml ocamlfind: [WARNING] Package `threads': Linking problems may arise because of the missing -thread or -vmthread switch $ ./a.out Hello F*! Obviously the command required is not as simple as it could be, but this is already an improvement since it provides a standard way of locating the needed OCAMLPATHs.

I don't think this works:
❯ echo '\\'
\\

Ah thanks! I misremembered, backslashes don't need escaping in single quotes.
