But assuming you do manage to compile and install Oleg's library, here's how you'd use it in an OCaml session:
#require "delimcc";; (* loading Oleg's library this way requires the findlib package *)
+ (* if you don't have findlib, you'll need to start ocaml like
+ * this instead: ocaml -I /path/to/directory/containing/delimcc delimcc.cma
+ *)
open Delimcc;; (* this lets you say e.g. new_prompt instead of Delimcc.new_prompt *)
let p = new_prompt ();;
let prompt thunk = push_prompt p thunk;;
