# SDL 3 built with Emscripten, static, for the web port (make web): the same
# release source the sdl3 component builds for the host (its pin is read from
# sdl3.sh, so there is one), with JoeyLib's patches for SDL's Emscripten code
# (installer/patches/sdl3Web), compiled to WebAssembly into
# toolchains/opt/sdl3Web.
