title: How can i split a binary in erlang
body: <p>What I want is, I think, relatively simple:</p>
  
  <pre><code>&gt; Bin = &lt;&lt;"Hello.world.howdy?"&gt;&gt;.
  &gt; split(Bin, ".").
  [&lt;&lt;"Hello"&gt;&gt;, &lt;&lt;"world"&gt;&gt;, &lt;&lt;"howdy?"&gt;&gt;]
  </code></pre>
  
  <p>Any pointers?</p>
