This package is a modified version of the CTAN package tufte-latex
which is under the Apache2 License 
(https://github.com/Tufte-LaTeX/tufte-latex). 

The xtufte-latex allows to use lualatex with OpenType or TrueType fonts
and also by default Biber instead of BibTeX!

It does _not_ work with the default tufte-latex package and pdflatex.
