+Down is an unintrusive user experience upgrade for the `ocaml`

+
+Simply load the zero dependency `Down` library in the `ocaml` toplevel
+and you get line edition, history, session support and identifier
+completion and documentation (courtesy of [`ocp-index`][ocp-index]).
+
+Add this to your `~/.ocamlinit`:
+
+    #use \"down.top\"
+
+You may also need to add this to your `~/.ocamlinit` and declare
+the environment variable OCAML_TOPLEVEL_PATH

+Supports most common syntax extensions, and extensible for others.

+- An indentor program, callable from the command-line or from within editors
+- Bindings for popular editors
+- A library that can be directly used by editor writers, or just for\n  
fault-tolerant/approximate parsing.
