MontaukOS - Third-Party Notices
===============================
MontaukOS is proprietary software governed by the MontaukOS Software License
Agreement (see license.txt). It incorporates or is distributed together with the
third-party components listed below, each of which remains the property of its
respective owner and is provided under its own license. The notices and license
texts in this file apply only to the corresponding third-party component and not
to MontaukOS as a whole.
This file is provided to satisfy the attribution and redistribution conditions of
those licenses. Where a component permits a choice of license, MontaukOS relies on
the option reproduced here.
================================================================================
1. Limine (bootloader)
================================================================================
Shipped as binary firmware payloads in the bootable image (e.g. BOOTX64.EFI,
BOOTAA64.EFI, BOOTIA32.EFI, BOOTRISCV64.EFI, BOOTLOONGARCH64.EFI,
limine-bios-cd.bin, limine-bios.sys, limine-uefi-cd.bin, and related files).

modification, are permitted provided that the following conditions are met:
1. Redistributions of source code must retain the above copyright notice, this
list of conditions and the following disclaimer.

Note: The build system also derives in part from the Limine C++ template, which
is released by Mintsuki and contributors under the Zero-Clause BSD (0BSD) license.
0BSD imposes no attribution or redistribution conditions; this acknowledgement is
provided as a courtesy only.

2. BearSSL (TLS / cryptography)
================================================================================
Linked into MontaukOS userspace networking components.

3. stb_image (JPEG image decoding)
================================================================================
Used as the single-header image decoder behind MontaukOS image/JPEG support
(programs/include/gui/stb_image.h). This is the "libjpeg" component referenced in
the build; it is in fact stb_image by Sean Barrett.
stb_image is dual-licensed (MIT OR public domain). MontaukOS relies on the MIT
option, reproduced here:

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.
This program is free software; you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation; either version 2 of the License, or (at your option) any later
version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY
WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A
PARTICULAR PURPOSE. See the GNU General Public License for more details.
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.

this Agreement modifies, supersedes, or limits the license terms applicable to
such third-party components. To the extent of any conflict between this Agreement
and a third-party license with respect to that third-party component, the
third-party license controls for that component only. The applicable copyright
notices and license texts for these components are set out in the
THIRD-PARTY-NOTICES file that accompanies the Software and are incorporated
herein by reference.
5. Feedback

perpetual, irrevocable, worldwide, royalty-free license to use and incorporate
such Feedback for any purpose, without obligation or attribution to you.
6. Term and Termination

Project regarding the Software and supersedes all prior or contemporaneous
understandings. If any provision is held unenforceable, the remaining provisions
