I have only little knowledge about LaTeX, basic formatting, basic math fomulae etc.. I found that LaTeX is hard to configure to my own flavor. Recently, I've heard about Docbook, which is also a typesetting mechanism, but much easier since it uses XML. So, if my main job using LaTeX/Docbook is writing a simple document (not a class book) with some mathematics, and I want easy configuration, and a highly constomizable application, which one is better, and is there any good book on Docbook?
