NetBSD has several articles that could and are converted to PDF. While the final conversion and its methods is another task, having a nice book layout is necessary.
In this task, you have to research the different styles a NetBSD article would need (i.e., code blocks, other blockquotes, special quotes for commands, for manpages, etc.) and everything around like a front page, the font, etc.
You can deliver the specification either as a Latex style or exactly written with some example images.
