Now that I have my book project basically running on mkiv (the layout probably has a few problems left, the main one currently being extra whitespace after a chapter heading compared to mkii), I’d like to try producing ePUB from it. ConTeXtgarden says I have to add a backend and points me to the info on the standard project structure (which I use), but there I don’t find anything about a backend. The extended example says that starting january 2015, things have changed with ePUB, which probably also applies to me as I only recently started with a fresh download of a current ConTeXt mkiv. So, can someone tell me what I need to do to get a basic ePUB output? And what command do I run to update my separate ConTeXt tree? And which one to find out what version I’m running? G
