This is a demo of how to include Mathematica notebooks in a latex document. See also \url{http://drorbn.net/AP/Projects/nb2tex/nb2tex.pdf} (written in Groningen!).

The files used to construct this document are all at \url{http://drorbn.net/AP/Projects/nb2tex/nb2tex.pdf}. The ``main'' file is {\tt Demo.tex}. It defines a few macros that detail how various types of Mathematica notebook cells should be formatted (especially see \verb$\nbpdfInput$ and \verb$\nbpdfoutput$, it contains all the text down to the separator line below, and it inputs {\tt TraditionalHopfStructure.tex}. That latter \verb$.tex$ file is produced automatically from the notebook \verb$TraditionalHopfStructure@.nb$ by running the code in the notebook \verb$Make.nb$.
