+# continuum_ppx
+
+An OCaml syntax rewriter for callback-based functions:
+
+```ocaml
+let%continue x = producer in body
+```
+
+expands to `producer (fun x -> body)`. The `let%cps` spelling also
+works. Patterns and nested bindings are supported. Recursive bindings and
+simultaneous `and` bindings produce a compiler error.
+
+Build and test with `make test`. Compile a consumer with
+`ocamlc -ppx ./continuum_ppx example.ml`. The executable uses OCaml's bundled
+compiler libraries and must match the consumer's compiler version.
+
+Install from this directory with `OPAMBUILDTEST=true opam pin add continuum_ppx .`.
+The package installs the `continuum_ppx` executable; it needs no external OCaml
+libraries or build tools beyond make.
