I&#x27;m geuninely curious, is this how these books are typeset?<p>I was at a conference a few years back and one of my favorite presentations was a guy from O&#x27;Riely. Up to that point most of their works were converted from docbook with XSLT to pdf,epub, or html. He had been working on HTMLBook[1] to write books in asciidoc, convert to (x)HTML5 and the conversions were written in CSS and used an antenna house processor.<p>It was an XML conference, so all things latex was a bit taboo. But in general, we handle a lot of XML in publishing.<p>[1] : <a href="https:&#x2F;&#x2F;github.com&#x2F;oreillymedia&#x2F;HTMLBook" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;oreillymedia&#x2F;HTMLBook</a>
