"""Assemble the build kit: what a player needs to build Ocarina of Time on their own PC with tools/make_game.py.

    python tools/make_kit.py --xlate <dir with nx2navi_xlate.exe and .id> [--ffx amd_fidelityfx_vk.dll]
                             [--ffx4 FOLDER]
                             [--dlss nvngx_dlss.dll | --no-dlss] [--dlssg nx2navi_dlssg.dll [--streamline SDK]]
                             [--prompt-art FOLDER [FOLDER ...]] [--out build/kit] [--zip]

The kit holds this repository's runtime/ with its shaders compiled (tools/build_shaders.py builds the SPIR-V headers
here, so a player's PC needs no shader compiler; their sources go along), recomp/, the build tools, the shader
translator built from tools/xlate,
NVIDIA's DLSS library with its notice (tools/dlss_pin.py: downloaded from NVIDIA's DLSS SDK repository and checked,
or --dlss; not with --no-dlss), DLSS Frame Generation in bin/dlssg/ with --dlssg (nx2navi_dlssg.dll from
tools/build_dlssg.py beside NVIDIA Streamline's runtime, tools/streamline_pin.py: downloaded from NVIDIA's Streamline
SDK release and checked, or --streamline), AMD's FSR 3.1 library with --ffx, its two FSR 4 libraries with --ffx4, the
button art with --prompt-art, and README-BuildKit.md; no game code, data or anything generated from the game.
check_content runs over the folder before it is zipped. The --xlate folder must hold a translator built from this
checkout's sources (tools/build_xlate.py check_built), and the --dlssg DLL must export every function
runtime/dlssg/nx2_sl.h declares (tools/build_dlssg.py check); the script stops first if not.

--prompt-art names folders that hold XGamepad, P5Gamepad and Keyboard_Mouse, or those three folders themselves: the
pictures tools/pad_prompts.py reads go into the kit's prompt-art folder (tools/prompt_art.py art_files), and
make_game.py draws the Xbox, PlayStation, Steam Deck and keyboard and mouse prompts from them. Without it the kit builds the game
with the game's own prompts only.
