4. DOOM engine (via doomgeneric)
|
|
================================================================================
|
|
Shipped as the bundled "doom" application (doom.elf), built from the doomgeneric
|
|
port of id Software's DOOM source release.
|
|
|
|
License: GNU General Public License, version 2 (GPLv2)
|
|
|
|
DOOM source code is Copyright (C) 1993-1996 id Software, Inc., is Copyright (C)
|
|
2005-2014 Simon Howard (Chocolate Doom lineage), and is licensed under the GNU
|
|
General Public License version 2. doomgeneric is Copyright (C) its respective
|
|
authors and contributors, likewise under GPLv2.

|
|
WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A

|
|
|
|
IMPORTANT: The DOOM application (doom.elf) is licensed under GPLv2, separately
|
|
from MontaukOS itself. The MontaukOS Software License Agreement does NOT apply
|
|
to doom.elf or to the doomgeneric/DOOM source. The full GPLv2 license text is
|
|
distributed with the corresponding source.
|
|
|
|
WRITTEN OFFER FOR SOURCE: The complete corresponding source code for the DOOM
|
|
application, under the terms of GPLv2, is available on request and is provided
|
|
alongside MontaukOS distributions. Contact: daniel@nexlink.cloud.
|
|
|
|
DOOM GAME DATA (doom1.wad): This notice and the GPLv2 license cover only the
|
|
DOOM engine code, NOT the DOOM game data. MontaukOS bundles "doom1.wad", the
|
|
DOOM shareware episode (Knee-Deep in the Dead), which is Copyright (C) id
|
|
Software, Inc. The shareware WAD is NOT covered by the GPL and is NOT public
|
|
domain. id Software's shareware terms permit free, non-commercial redistribution
|
|
of the unmodified shareware WAD, but do not grant rights for commercial
|
|
distribution or modification. If MontaukOS is ever distributed commercially, the
|
|
shareware WAD should be removed and replaced with a freely licensed alternative
|
|
(e.g. the Freedoom project's freedoom1.wad / freedoom2.wad, released under a
|
|
BSD-style license), or distributed only with id Software's permission. The
|
|
registered/commercial DOOM WADs (e.g. doom.wad, doom2.wad) are separate
|
|
copyrighted assets and are NOT distributed with MontaukOS.
