 # OctaCore license

 All new OctaCore code is provided to you under the terms of the BSD-2-Clause
 license, while the original Tesseract/Sauerbraten portions retain their original
 license. OctaCore only ships the altered source code of the original projects,
 without the media content.

 Sauerbraten source code license, usage, and documentation.

 You may use the Sauerbraten source code if you abide by the ZLIB license
 http://www.opensource.org/licenses/zlib-license.php
 (very similar to the BSD license):


 LICENSE
 =======

 Sauerbraten game engine source code, any release.

 Copyright (C) 2001-2020 Wouter van Oortmerssen, Lee Salzman, Mike Dysart, Robert Pointon, and Quinton Reeves

 LICENSE NOTES
 =============
 The license covers the source code found in the "src" directory of this
 archive as well as the .cfg files under the "data" directory. The included 
 ENet network library which Sauerbraten uses is covered by an MIT-style 
 license, which is however compatible with the above license for all 
 practical purposes.

 Game media included in the game (maps, textures, sounds, models etc.)
 are NOT covered by this license, and may have individual copyrights and
 distribution restrictions (see individual readmes).


 USAGE
 =====
 Compiling the sources should be straight forward.

 Unix users need to make sure to have the development version of all libs
 installed (OpenGL, SDL, SDL_mixer, SDL_image, zlib). The included
 Makefile can be used to build.

 Windows users can use the included Visual Studio project files in the vcpp 
 directory,  which references the lib/include directories for the external 
 libraries and should thus be self contained. Release mode builds will place 
 executables in the bin dir ready for testing and distribution.

 An alternative to Visual Studio for Windows is MinGW/MSYS, which can be compiled
 using the provided Makefile. Another alternative for Windows is to compile under
 Code::Blocks with the provided vcpp/sauerbraten.cbp project file.

 The Sauerbraten sources are very small, compact, and non-redundant, so anyone
 wishing to modify the source code should be able to gain an overview of
 Sauerbraten's inner workings by simply reading through the source code in its
 entirety. Small amounts of comments should guide you through the more
 tricky sections.

 When reading the source code and trying to understand Sauerbaten's internal design,
 keep in mind the goal of Cube: minimalism. I wanted to create a very complete
 game / game engine with absolutely minimal means, and made a sport out of it
 keeping the implementation small and simple. Sauerbraten is not a commercial 
 product, it is merely the author's idea of a fun little programming project.
