>Very few (if any) fancy and well typespeced books by major publishers have been made with LaTeX. I know, because I know that industry. What do they use, then? (I'm actually pretty curious, because I am writing a dissertation that I currently build with LaTeX, but I find it much nicer to write in Org mode. I'm doing whatever I can to avoid a hard dependency on LaTeX for the backend, and to allow exporting to multiple formats.) Why do they use whatever typesetting solution(s) they use? Does it actually produce better/nicer output than LaTeX (for non-math text)? Does it just have nicer syntax or friendlier error messages? What's the advantage?
