Source: xsok Version: 1.02-19 Severity: serious Justification: possible DFSG violation
[Please do not Cc: me, as I’m “on the list,” so to say, and I prefer to reserve my inbox for private communication only. I’d have set up Mail-Followup-To:, but there doesn’t seem to be a way to make it point to the report being filed.] The xsok debian/copyright file seems to suggest that xsok was created solely by Michael Bischoff: $ tar --xz -xO -- debian/copyright < xsok_1.02-19.debian.tar.xz This is Debian GNU/Linux's prepackaged version of xsok. xsok was written by Michael Bischoff <michael.bisch...@gmx.net>. The upstream source was downloaded from ftp://ftp.io.com/pub/mirror/FreeBSD/ports/distfiles/xsok-1.02-src.tar.gz The current Debian maintainer is Peter Samuelson <pe...@p12n.org>. Much of the packaging work was done by previous Debian maintainers Sven Rudolph and Joel Rosdahl. Copyright (c) 1994 by Michael Bischoff (m...@mo.math.nat.tu-bs.de) [GNU GPL 2+ notice follows.] There’re two issues with this. First, xsok includes doc/cyberbox.doc, authored by Doug Beeferman (I presume lib/Cyberbox/ files are also derivatives rather than original xsok work.) The .doc file (quoted below) appears to allow verbatim redistribution of the respective game, but there’s no indication that ‘modifications and derived works’ are allowed (as DFSG requires) as well: S O R T A F R E E W A R E N O T I C E This game can be distributed freely and played free of charge. If you like it, however, I wouldn't mind a small donation for the effort I put into writing the program and (ughh!) in making the levels. I say "ughh!" because making the levels was by far the more time-consuming of the two projects. Neither is there any such indication on http://dougb.com/ . (I intend to contact the author of Cyberbox shortly to comment on this issue and (or) possibly re-release at least the portions of xsok derived from the original game in DFSG- compliant fashion.) Worse still, the ‘screens’ (= maps, levels) included in lib/Sokoban/ appear to mostly come from the original, proprietary version(s) of Soko-Ban. Consider, e. g.: http://web.archive.org/web/2023/https://www.mobygames.com/game/1715/soko-ban/ http://web.archive.org/web/20230407165659im_/https://cdn.mobygames.com/8e54fc3c-bee0-11ed-9c42-02420a000140.webp http://web.archive.org/web/20230407165658im_/https://cdn.mobygames.com/0b7522d4-c204-11ed-ab6b-02420a000194.webp The first Soko-Ban screen, identical to lib/Sokoban/screen.01 . http://web.archive.org/web/20230407165658im_/https://cdn.mobygames.com/058c7f98-ab6b-11ed-aaf5-02420a00019c.webp The second Soko-Ban screen, identical to lib/Sokoban/screen.02 . Moreover, taking a look at an earlier curses-based implementation of the game from [1], which (according to its README.v2, as quoted below) borrows screens from ‘the PC-version’, we find out that likely /all/ levels from 1 to 50 inclusive are taken from other software, while several other levels (86‒88) are derived from the same. I’m not aware of any evidence to suggest that the original Soko-Ban might be out of copyright or ever released as free software, from whence I conclude it’s likely proprietary, including the level designs. The first thing I have to say is that I don't have the sources for SOKOBAN under MS-DOS. I believe that this program is copyrighted. I took only the idea and the screens of the PC-version.
