title: Can I create completions file for rlwrap?
body: <p>I use the following script to start the toplevel:</p>
  <pre class="lang-sh prettyprint-override"><code>breakchars=&quot;(){}[],^%$#@\&quot;\&quot;;:''\\&quot;
  exec rlwrap --remember -c -b &quot;$breakchars&quot;  -f &quot;$HOME&quot;/.ml_completions -S '&gt; ' ocaml -init ~/.ocamlinit &quot;$@&quot;
  </code></pre>
  <p>Then how can I build the .ml_completions file so that I can auto-complete input in the toplevel?</p>
