# Monta o Z.E.A.L.O.T.S. (stcucufa, 7DRL 2024, MIT) a partir do commit fecadd3 de github.com/stcucufa/zealots: so a pasta
# 7drl/ (index.html, game.js e style.css, sem mudancas; o jogo e JavaScript puro sem build) e o LICENSE. A pagina da
# raiz do repositorio (texto de apresentacao, capa e links para itch.io e GitHub) nao entra: as criaturas do jogo sao
# letras na tela e os nomes de personagens de terceiros citados nesse texto nao aparecem no jogo.
#
#   src/FredGames.Bundler/Builds/build-zealots.sh
#
# Saida: artifacts/build/zealots-fecadd3/zealots-fecadd3-dist.tar.gz (pasta dist/; igual em dois builds seguidos).
