Both fonts below are compiled into the IW4L binary with `include_bytes!`, so

Third-party source code
--------------------------------------------------------------------------------

No third-party source code is vendored in this repository, and the build links
no third-party project named below. The Rust crates compiled into the IW4L
binary, with their licence and copyright texts, are listed in
THIRD-PARTY-LICENSES.txt; the binary embeds that file and `iw4l licenses`
prints it. `cargo xtask licenses` regenerates it from Cargo.lock.

References consulted during development
--------------------------------------------------------------------------------

These projects were read while working out how the original games behave. They
are named here because the reading happened, not because anything of theirs is
distributed: none of them is vendored, linked, bundled or otherwise shipped.

OpenAssetTools — https://github.com/Laupetin/OpenAssetTools
  Open-source modding tools for older Call of Duty games. Its asset-structure
  headers document the on-disk layouts IW4L reads. Licensed under GPLv3.

oat (iw4x-x64 fork of OpenAssetTools) — https://github.com/iw4x-x64/oat
  The x64 fork, at revision 3a7442dee5ce040cfdb8da23fdb9fb525b5f743e, is the
  tree whose IW4MS headers were read for the 64-bit FastFile layouts.
  Licensed under GPLv3, like its upstream. No file in this repository is
  compiled against, generated from or distributed with those headers.

IW4x — https://github.com/iw4x/iw4x-client
  A custom client for Call of Duty: Modern Warfare 2 (2009), with dedicated
  servers, security fixes and modding support. Read as a cross-reference for
  asset and protocol behaviour. Licensed under GPLv3.

KisakCOD — https://github.com/SwagSoftware/KisakCOD
  A Call of Duty 4 open-source reimplementation. Read as a cross-reference for
  engine structure. IW4L targets IW4, so this is a neighbouring generation of
  the same engine family, not the same codebase.

t6-scripts (Plutonium) — https://github.com/plutoniummod/t6-scripts
  Decompiled Black Ops II multiplayer scripts. Read for how Black Ops II
  equipment behaves (Bouncing Betty, Shock Charge, Trophy System, Sensor
  Grenade, EMP Grenade, C4, Tactical Insertion) and for its constants. IW4L's
  `crates/assets/src/t6_equipment.gsc.txt` is written for IW4L, not copied
  from it.

Ghidra — https://github.com/NationalSecurityAgency/ghidra
  The software reverse engineering framework the original game binaries were
  read with. A development tool: none of it, and none of its output, is
  committed here or distributed with IW4L. Licensed under Apache 2.0.

FFmpeg — https://ffmpeg.org/
  Read and queried during development of the native T5 WMA2 decoder.
  Wire codeword mappings and exponent band grids were measured by submitting
  decoder queries. No FFmpeg source or executable is distributed or linked.

OxideAV WMA — https://github.com/OxideAV/oxideav-wma
  Evaluated and read as a reference for WMA2 decoding. No source is vendored
  or compiled into IW4L.

No Call of Duty game data is contained in this repository or in any IW4L
release archive. IW4L reads game data from a copy of the game the user already
owns and has installed. Call of Duty, Modern Warfare, Black Ops, related
trademarks and all original game assets belong to their respective owners.
