This package's original tooling (build scripts, Makefile, launcher) is
licensed under the MIT License - see LICENSE.

The systemshock binary and its shared libraries in lib/ are built from
Shockolate (https://github.com/Interrupt/systemshock), which is licensed
under the GNU GPLv3 - see LICENSE.Shockolate. It is included unchanged
and is not relicensed by this project's MIT license.

Game assets are not included - see res/GET_ASSETS.txt.

The Android build additionally bundles:

- GL4ES (https://github.com/ptitSeb/gl4es), vendored and patched (see
  android/gl4es-patches/) and compiled from source at APK build time as
  lib/arm64-v8a/libGL.so. It is MIT-licensed.
- The Khronos Group's OpenXR-SDK loader
  (https://github.com/KhronosGroup/OpenXR-SDK), prebuilt unmodified as
  lib/arm64-v8a/libopenxr_loader.so. It is Apache 2.0-licensed.

The Windows build (cross-compiled via MinGW - see README's "4.2. Windows
cross-build") additionally bundles:

- GLEW (http://glew.sourceforge.net/), unmodified, as glew32.dll - used
  for OpenGL extension loading, which Windows' own opengl32.dll doesn't
  provide past OpenGL 1.1 (Linux instead gets this straight from Mesa's
  headers, needing no separate loader library - see
  engine/src/MacSrc/OpenGL.cc). It is licensed under a combination of the
  Modified BSD License, the MIT License, and the Khronos License, all
  permissive.
- The MinGW-w64 runtime's winpthreads library, as libwinpthread-1.dll. It
  is MIT-licensed. (GCC's own runtime, libgcc/libstdc++, is linked
  statically into systemshock.exe instead of shipped as a DLL, under the
  GCC Runtime Library Exception - this doesn't subject the rest of the
  binary to the GPL.)
