# Compila o Crypt of Grimwin (roguelike de possessao, 7DRL 2018, do Team Kalamakkara; MIT; TypeScript + PixiJS 4 +
# rot.js) para a web a partir do fonte, num commit fixo, com o Node 24.21.0 (artifacts/tools) e o package-lock do autor:
# npm ci + webpack 3 (o do projeto). Unica diferenca para o "npm run build" dele: a configuracao do webpack
# (Builds/crypt-of-grimwin/webpack.fredygames.config.js) sem o HappyPack e o ForkTsChecker, que nao rodam no Node
# atual, e sem o source map embutido; o ts-loader compila so (transpileOnly), como o do autor em modo happypack.
# O index.html gerado carrega ../dist/index.js (a estrutura do repositorio); aqui o script fica ao lado do HTML.

# site.tar.gz (a pasta do jogo) tem que sair igual em dois builds seguidos.
