Is Docbook dead? I see it mentioned here only as an output format, between HTML and PDF, which sounds strange because I don't know any way to view it without first converting it to something like HTML or PDF. Docbook is a bit verbose, but highly semantic. I always liked the idea of Docbook, though I could never get it to work well. At best, you waste a lot of time installing and configuring a big slow chain of programs to get ugly HTML or PDF that's virtually impossible to adapt to the style of your webpage or book. Today the docbook.org "Tools" tab only points to a couple of XSLT stylesheets, so it looks like they haven't improved since last I tried. It's one of those technologies that I say "I should learn that...", look at for a couple days, and then say "Maybe I'll check back in 5 or 10 years." Like XSLT.
