Hi, I don't know if you are aware of it, but the README at ftp://tug.ctan.org/pub/tex-archive/info/examples/ltt/README now states: <snip> "License is (according to the upload notice by the author): Debian Free Software Guidelines." I also had a short look at the book, there's nothing in it about the examples, except for the download location (so I didn't find anything contradicting the above). Thanks Thomas
