Similar here, i use Docbook and then convert to PDF with FOP, this all via Red-Hat's Publican. Recently i actually started writing in asciidoc, which i convert to docbook and then to pdf and other formats. This is now pretty slick. Both asciidoc and docbook also provide good localization tooling for gettext, which i need.
