An anonymous reader writes: I'm a professor and next semester, I'll be writing a college textbook which will be free (as in beer). What I'd like is both a web version and an ePub version, with the latter being generated from the former. That is, when I update the web version, I'd like to be able to produce a new ePub version with no additional changes. I'd like help in two areas: (1) Suggested work flow: I currently hand code all web/CSS code, but as I envision updates, I wonder if there's a more efficient way of going from text to web to ePub. (2) Suggested templates or examples that show a good HTML5/CSS3 web and ePub format for a textbook. I don't want/need comments, discussions, etc, as that happens in the University's CMS system.
