This file describes the licencing terms for AudioQuake, the Level Description Language (LDL) tools and the supporting data and programs distributed with them (not all created by us). It exists to make sure that you're completely aware of what you (and we) can and can't do with the software. After the following summary, each section describes a component of the AudioQuake and LDL distribution and the licence used for it.
There are three licences in use:
- The documentation (AudioQuake user and development manuals, and Level Description Language tutorial, as well as other text files such as this) is distributed under the GNU Free Documentation Licence (GFDL).
- The Prototype textures are copyright 2017-2019 by Aleksander "Khreathor" Marhall ([email protected]; https://twitter.com/khreathor). They're freely usable in Quake or any game, as long as Aleksander gets a credit, which is totally reasonable: thanks Aleksander!
- Everything else is distributed under the GNU General Public Licence (GPL), version 2 or later.
This is the QuakeWorld game engine on which AudioQuake is based. It is distributed under the GNU General Public Licence (GPL). For more information, please read the COPYING file.
This repo builds on id's "Quake Tools" code, which is also released under the GNU GPL.
That code is linked to this repo via a submodule, and the compiled tools are distributed as part of the AudioQuake and LDL bundle. Some patches (maintained in this repo) are applied to ensure the software will build, and to relax constraints it places on the paths where WAD files are located. Those patches, as they're both applicable to GPL'd software, and reside in this repo, are too distributed under the GPL.
The Open Quartz game data, which includes sounds, textures, models, maps, gamecode (although the AGRIP gamecode is used instead) and UI graphics, is included out-of-the-box. This means you can have fun right away, even if you haven't bought Quake. You can make maps and play multiplayer games with Open Quartz.
The project is hosted on another service, but development stopped some time ago, so the latest data files are included here and, as usual, are covered by the GNU GPL.
Our modified gamecode and sounds are the resources we've added to the ZQuake engine, vanilla gamecode and in-game data to make it accessible. The licence used here is the GPL. For details on what this means, please consult the COPYING file.
We did not create all of the sounds from scratch: some are derivative works and some were donated to us. However they are all distributed under the GPL too. Please check out the AudioQuake ACKNOWLEDGEMENTS file for details---and many thanks to everyone on whose work we've been able to build!
The launcher is a separate program to the game engine and data. It provides a UI for running, customising, modding and making maps for the game, as well as text-to-speech facilities for when the game is running. Again, this is distributed under the GNU GPL. For details on what this means, please consult the COPYING file.
The LDL library and UI (integrated into the launcher) were developed as part of AGRIP and are released under the GNU GPL, as above.
These textures are used in the high-contrast variants of maps. They are freely usable in Quake or other games, and are copyright 2017-2019 by Aleksander "Khreathor" Marhall ([email protected]; https://twitter.com/khreathor). Thank you, Aleksander!
The manual for AudioQuake and documentation for LDL are distributed under the GNU Free Documentation Licence (FDL). A copy of this is included in an appendix of the AudioQuake manual.
