As a true CS professor, Knuth distinguishes between the program (i.e. the code of the program) and the name of the program (file name of the code for systems with file naming conventions). 2. The code is in the public domain. Anybody can do anything with it. 3. The associated set of names is *not*. I share this inderstanding with the developers of derivatives of Knuth's work like pdfTeX, EC fonts etc: they freely used fragments of Don's code but changed the names. Since their work is endorsed by Knuth (he sent a nice letter to Han The Thanh's thesis committee, for example), it is probably an adequate understanding. Whether these conditions are DGSG-free or not, is a subject of a heated discussion on the debian-legal. My personal opinion is that either they are or, if not, they should be grandfathered: TeX used to be the greatest example of free software for decades, and it would be a shame to lose this. -- Good luck -Boris Clothes make the man.
