+ReScript builds on parts of OCaml:
+
+* [`jscomp/core/lam_pass_exits.ml`](jscomp/core/lam_pass_exits.ml)
+* [`jscomp/core/lam_pass_lets_dce.ml`](jscomp/core/lam_pass_lets_dce.ml)
+
+These modules were adapted from [`ocaml/bytecomp/simplif.ml`](ocaml/bytecomp/simplif.ml) for
+JavaScript specific optimization purposes.
+
+* [`jscomp/main/js_main.ml`](jscomp/main/js_main.ml)
+
+`jscomp/main/js_main.ml` is adapted from [`ocaml/driver/main.ml`](ocaml/driver/main.ml). It is the main entry
+point of the underlying compiler.
+
+*  [`jscomp/stdlib-406`](jscomp/stdlib-406)
+
+`jscomp/stdlib-*` is copied from [`ocaml/stdlib`](ocaml/stdlib). It is compiled to JavaScript and included with ReScript.
+
+ReScript imported one file from [jsoo](https://github.com/ocsigen/js_of_ocaml)
+
+* [`jscomp/core/js_dump.ml`](jscomp/core/js_dump.ml) (pretty printer)
+
+This file was imported but changed significantly in iterations later.
+
+* [`jscomp/test`](jscomp/test)
+
+`jscomp/test` is based on [`ocaml/testsuite`](ocaml/testsuite).
+
+ReScript unit test builds on parts of [OUnit](http://ounit.forge.ocamlcore.org/)
+
+* [`jscomp/ounit`](jscomp/ounit) is adapted from ounit, the unit test
+  utilities are only used for dev purpose, they are not required for distribution
