# Prepara o Cruel Mines (um campo minado "cruel mas justo", MIT, Pawel Marczewski / pwmarcz; o repositorio chama o jogo de
# "Kaboom") a partir do commit 2c5cc17 de github.com/pwmarcz/kaboom. Nao precisa de build (HTML, CSS e JavaScript puros, com
# Bootstrap 4.3.1, MiniSat compilado para JS e long-press-event, todos MIT e com o aviso de copyright no proprio arquivo).
#
# Mudancas, todas no index.html e feitas aqui (cada uma falha se o texto esperado nao existir):
#  - titulo e cabecalho: "Kaboom" (titulo de um jogo da Activision) vira "Cruel Mines";
#  - os quatro niveis perdem os nomes de um jogo comercial e viram Easy, Medium, Hard e Expert, com o tamanho a vista;
#  - saem a secao "See also" (YouTube, Tatham, minesweepr, GitHub e blog do autor) e o rodape com o link do autor: nada da
#    pagina leva para fora do site. O credito do autor fica no texto da pagina do jogo e no LICENSE.
# Nenhuma requisicao sai do site (o jogo nao usa fonte, imagem de terceiros nem rede).
#
#   src/FredGames.Bundler/Builds/build-cruel-mines.sh
#
# Saida: artifacts/build/cruel-mines-2c5cc17/cruel-mines-2c5cc17-site.tar.gz (pasta site/); dois builds seguidos dao os mesmos bytes.
