<p style="margin-top:0;margin-bottom:0">I'm wondering if I could get some advise regarding xref.</p>
<p style="margin-top:0;margin-bottom:0">I've found across a number of projects, anything using Cowboy triggers similar alerts for me to below:</p>

<p style="margin-top:0;margin-bottom:0"><span>===> Warning: api_handler:init/2 is unused export (Xref)</span></p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">The init/2 function is most definitely used - it's the Cowboy callback used exactly the same way as the demo echo server does here:</p>

<p style="margin-top:0;margin-bottom:0">I'm hoping to incorporate the xref test into my CI workflow, but I'd need to understand first how to convince it that Cowboy functions are not "unused". Is this a bug in xref or rebar?</p>
