OCaml's utop: importing external modules
<p>I'm interested in introducing <a href="https://github.com/inhabitedtype/angstrom" rel="nofollow noreferrer">Angstrom</a>, a parsing combinator library, to a project of mine.</p>

<p>I installed Angstrom to my system with <code>opam</code> as follows:</p>

<pre><code>$&gt; opam install angstrom
</code></pre>

<p>I also successfully compiled the project with reference to the module in question using <code>ocamlfind</code>: </p>

<pre><code>$&gt; ocamlbuild -use-ocamlfind -pkgs 'angstrom' project.byte
</code></pre>

<p>Surprisingly, I'm having trouble importing Angstrom to the <code>utop</code> repl. Commands like <code>#open Angstrom</code> indicate a value bound to the module name. I have searched for documentation of module imports from the repl, but I haven't found the result that I'm looking for.</p>

<p><strong>What's the best way to reference an external module from <code>utop</code>?</strong></p>
