Just a note: if you are thinking of writing docs to be used as Qt help files (like the ones you see in assistant) maybe you should take a look here:

It's a script to convert restructured text (plain text with light markup) into full-fledged Qt help files, including TOC, multiple nested sections, keywords, filters and the rest.
