# Exporta o One Minute Away (Denis Bourge / Srynetix, Ludum Dare 51, MIT; github.com/Srynetix/one-minute-away) para a
# web com o Godot 3.5.3 oficial (o jogo foi feito no 3.5.1): modelo webassembly_release (sem threads: nao precisa de
# SharedArrayBuffer nem de COOP/COEP), sem PWA. O jogo usa o plugin do proprio autor, o sxgd (MIT,
# github.com/Srynetix/sxgd), que no repositorio do jogo e um submodulo (pasta vazia): baixamos o commit exato
# que o jogo aponta (3154b93) e o colocamos em addons/sxgd. Mudancas, todas feitas aqui:
#   1. sxgd sem doc/ (105 MB de documentacao gerada) nem .github/;
#   2. o jogo sem art/ (projetos do FL Studio, so de autoria) e sem a imagem do logo do Ludum Dare
#      (assets/3rd/ludumdare.png, marca registrada): a tela de abertura passa a dizer "Ludum Dare" em texto;
#   3. o export deixa de fora o modulo Font Awesome do sxgd (o jogo nao o usa; fica no fonte), promo/ e o
#      rascunho de tileset (*.png~).
#
#   src/FredGames.Bundler/Builds/build-one-minute-away.sh
#
# Saida: artifacts/build/one-minute-away-be7c52c/{web/,one-minute-away-be7c52c.tar.gz}, que o bundle.yaml do jogo
# confere pelo SHA-256. O tar.gz (jogo + sxgd, com as mudancas acima) sai igual a cada execucao.
