#use "topfind"; not needed with 'rtop', and crashes 'rtop' to boot

[dchambers]

I'm an OCaml novice (thanks to Reason 😄) and I wanted to use the opam installation of Reason along with containers as my standard library. After installing it with:

opam install containers

I found that if I entered #use "topfind"; into rtop then it exited with this error:

Fatal error: exception Syntax_util.Error(_, _)

whereas doing the same worked great in utop.

This is probably obvious to OCaml practitioners, but it wasn't to me so I thought I'd share. It turned out that by just not running that line and proceeding straight to the #require "containers"; line then everything worked correctly, and I was able to open Containers; and use it just fine.

This issue can probably be immediately closed, though maybe this should be documented in the readme.MD?
