Not Ruby, it&amp;#x27;s written in Rust instead.&lt;p&gt;It&amp;#x27;s very easy to customize either via plugins with Rust or by overriding template files. While the linked article is cool, it seems like a lot of effort to maintain such a set up. Then again, if you&amp;#x27;re a Ruby expert I could see this being worth it.</text><parent_chain></parent_chain></comment><story><title>Ruby for eBook Publishing</title><url>https://nts.strzibny.name/ruby-for-ebook-publishing/</url></story>
