# Exporta o Viva Hexagon! Feat. Ipulo (zeddy1267; quebra-cabeca de hexagonos para 1 ou 2 jogadores; codigo GPL-3.0,
# imagens e audio CC BY-SA 4.0 do autor, fontes Londrina e Press Start 2P SIL OFL; gitlab.com/zeddy1267/vivagon)
# para a web com o Godot 3.5.3 oficial (o projeto e do Godot 3, GLES2): modelo webassembly_release (sem threads),
# sem PWA. O export_presets.cfg (preset "Web") e nosso, ao lado deste script. Mudancas no projeto, todas visiveis
# no fonte publicado (o tar.gz ja as traz):
#   1. os botoes dos creditos que abriam sites (OS.shell_open) nao fazem mais nada (viva-hexagon/web.patch);
#   2. tres efeitos sonoros de terceiros sem licenca registrada saem: fire.wav (sem uso no jogo; tem a etiqueta de
#      outro autor, "Damien H-Devaux"), smack.wav ("AX Entity") e player/balloon_pop.wav ("Belanhud"); os dois ultimos
#      sao tocados pelo jogo e trocados por sons sinteticos gerados aqui por viva-hexagon/gen-sounds.py (CC0);
#   3. o export deixa de fora o README.md.
#
#   src/FredGames.Bundler/Builds/build-viva-hexagon.sh
#
# Godot 3 precisa de duas passadas depois de "-e --quit" (a primeira exportacao ainda perde importacoes).
#
# Saida: artifacts/build/viva-hexagon-497ebae/{web/,viva-hexagon-497ebae.tar.gz}, que o bundle.yaml do jogo confere
# pelo SHA-256. O tar.gz e o fonte publicado (o projeto no commit pinado ja com as mudancas 1 e 2) e sai igual a
# cada execucao.
