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.

  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
  included on the MontaukOS ISO at 0:/os/licenses/GPL-2.0.txt.

  application, under the terms of GPLv2, is available on request and is provided
  alongside MontaukOS distributions. Contact: daniel@nexlink.cloud.

  DOOM GAME DATA: This notice and the GPLv2 license cover only the DOOM engine
  code, NOT any DOOM game data. MontaukOS does NOT distribute any DOOM WAD files;
  they are proprietary content of id Software, Inc. To play, users must supply
  their own legally obtained WAD, or a freely licensed alternative such as the
  Freedoom project's freedoom1.wad / freedoom2.wad (BSD-style license).

5. Flat Remix (icon theme)
================================================================================
The MontaukOS desktop and applications use icons from the Flat Remix icon theme
by Daniel Ruiz de Alegria. MontaukOS ships a curated subset of the theme
(renamed and reorganized for MontaukOS) in SVG form on the ISO (0:/icons/ and
per-application icon files).

  Copyright (C) Daniel Ruiz de Alegria <daniel@drasite.com>
  Upstream: https://github.com/daniruiz/flat-remix

  the terms of the GNU General Public License as published by the Free Software
  Foundation, either version 3 of the License, or (at your option) any later
  version.

  ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
  FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.

  MontaukOS itself. The MontaukOS Software License Agreement does NOT apply to
  the icon files, which remain under GPLv3. The full GPLv3 license text is
  included on the MontaukOS ISO at 0:/os/licenses/GPL-3.0.txt.

  MODIFICATIONS: The icons shipped with MontaukOS are a modified subset of Flat
  Remix (files selected, renamed, and reorganized for MontaukOS; first modified
  2025). These modified versions are likewise available under GPLv3.

  CORRESPONDING SOURCE: The icons are distributed in SVG form, which is their
  source (preferred form for modification); the files on the ISO are the
  corresponding source. The complete unmodified theme is available from the
  upstream repository above, and the MontaukOS-modified set is available on
  request: daniel@nexlink.cloud.
