# Exporta o HedgeClog (semi-confituriers, GMTK Game Jam 2021; GNU GPL v3, musica "Wonderful" de Scott Buckley
# CC BY 4.0, github.com/semi-confituriers/HedgeClog) para a web com o Godot 3.2.2 oficial (a versao do
# projeto): modelo webassembly_release (sem threads: nao precisa de SharedArrayBuffer nem de COOP/COEP), sem
# PWA. O repositorio traz um export_presets.cfg que nao serve para a nossa pagina; o nosso fica ao lado deste
# script. Mudancas no projeto, todas feitas aqui (o fonte GPL publicado e o projeto ja modificado):
#   - text/Impact.TTF (fonte comercial da Monotype) vira Anton (SIL OFL 1.1, google/fonts no commit pinado,
#     conferida pelo SHA-256), com o OFL.txt ao lado;
#   - saem os dois cartazes de meme (poster-doge e poster-thisisfine, com os nos que os mostram nas fases 14 e 9)
#     e todos os arquivos .kra (fontes de desenho do Krita, com versoes dos memes).
#
#   src/FredGames.Bundler/Builds/build-hedgeclog.sh
#
# O editor (macOS) e os modelos de exportacao vem do release 3.2.2-stable do GitHub, conferidos pelo SHA-256
# e ficam em artifacts/tools/godot-3.2.2, instalados sob lockf (outros scripts podem estar instalando ao
# mesmo tempo). O editor roda com HOME dentro da pasta de saida (configuracao e modelo isolados).
#
# Saida: artifacts/build/hedgeclog-f0bcfb2/{web/,hedgeclog-f0bcfb2.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
# acima) e sai igual a cada execucao.
