The problem is some files[1] has: | ermission is granted for unrestricted non-commercial use | [0] - https://anonscm.debian.org/cgit/pkg-multimedia/audacity.git/tree/lib-src/libnyquist/nyquist/license.txt [1] - https://anonscm.debian.org/cgit/pkg-multimedia/audacity.git/tree/lib-src/libnyquist/nyquist/xlisp/xlisp.c I am a little bit confuse about SGML: xhtml-symbol.ent xhtml-special.ent xhtml.lat1.ent Thera are open source alternatives, as said here[2]: Open-source implementations Significant open-source <https://en.wikipedia.org/wiki/Open_source_software> implementations of SGML have included: * ASP-SGML <http://ftp.sunet.se/pub/text-processing/sgml/ASP-SGML/> * ARC-SGML <http://ftp.sunet.se/pub/text-processing/sgml/ARC-SGML/>, by Standard Generalized Markup Language Users', 1991, C language * SGMLS <http://ftp.sunet.se/pub/text-processing/sgml/SGMLS/>, by James Clark, 1993, C language * Project YAO <http://ftp.sunet.se/pub/text-processing/sgml/YAO/>, by Yuan-ze Institute of Technology, Taiwan, with Charles Goldfarb, 1994, object * SP <http://www.jclark.com/sp/index.htm> by James Clark, C++ language [2] - https://en.wikipedia.org/wiki/SGML Regards, Herbert
