But I don’t know “modern” references. In a terminal, running<div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>man re_format</div><div class=""><br class=""></div><div class="">will give you the man page, which does have all the information. I can’t say it’s super-illuminating, but it will give you all you need to know.
