# Compila o Cityforge (versao modificada do micropolisJS de Graeme McCutcheon, GPL-3 com os termos adicionais da Electronic
# Arts; TypeScript/JS + jQuery 3.7.1, webpack 5) a partir do commit f13a162 de github.com/graememcc/micropolisJS, com o Node
# 24.21.0 de artifacts/tools e o package-lock.json do autor ("npm ci").
#
# Mudancas (cityforge/cityforge-fredygames.patch): nome novo na interface (a licenca proibe distribuir modificacao com a marca
# do jogo original e exige marcar como modificada), sem o widget do Twitter, doacoes, links externos, fonte do Google, paginas
# about/name_license, chave do save no localStorage propria ("cityforgeGame") e build id fixo (sem git).
#
#   src/FredGames.Bundler/Builds/build-cityforge.sh
#
# Saida: artifacts/build/cityforge-f13a162/cityforge-f13a162-dist.tar.gz (dist/); o tar.gz tem que sair igual em dois builds.
