Looking at http://www.delilinux.de/oksh/oksh-0.3.tar.gz, I see: The copyright notice at the top of alloc.c is still there, providing (I presume correctly) sole attribution to Marc Espie. The file mknod.c is gone, per the comments on the site ("Removed internal mknod builtin command"). The file oksh-0.3/LEGAL is identical to revision 1.2 of /usr/src/bin/ksh/LEGAL in the OpenBSD CVS repository. In addition to those, oksh-0.3/COPYING is the GNU GPLv3, and oksh-0.3/README.oksh says oksh is licensed under the GPLv3, see COPYING. oksh contains code originally released as Public Domain and BSD 3-clause License. >From my understanding, the author of the port has met the requirements of the 2-clause BSD license under which alloc.c is distributed. They refer to it as the 3-clause BSD license, which GNU appears to do as well (http://www.gnu.org/philosophy/license-list.html#ModifiedBSD), depending on where you look (http://www.gnu.org/licenses/info/BSD_2Clause.html). -- Matthew Weigel hacker unique & idempot.ent
