\pagebreak
Pagebreak and linebreak has to be done manually with pygmentize, this feature is
not yet implemented. Open the appendix.tex file and see the source code
afterwards how the pagebreak is done. For that the appendix.tex has to be
written with pagebreaks, so that the layout of the pages is done manually.

Linebreaks are easier to do, just check that the lines are in the box of the pdf
file, otherwise make a linebreak yourself.
