I want to produce a
Sorry for the n00b way of posting this, but it seems I'm unable to find anything around (compared to LaTeX). And onestly I'm very surprised about that.
Docbooks are XML, and get transformed to output formats using xslt processing and css stylesheets.
There seems to be a Debian package to help you called dblatex. It seems to convert from docbook => latex => dvi => pdf under the hood, so be prepared to pull in a bunch of packages for it.
Sorry I can't help further; I use neither docbook format nor the Debian distribution.
