I want to produce a PDF file out from a DocBook source on a Debian system. What should I do?
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 are some resources online: DocBook xsl seems promising. This docbook format page also.
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.
