# Prepara o Gomoku (MIT, Yao Yujian / yyjhao; jQuery Mobile + um Web Worker com a IA nega-scout) a partir do commit a664ec1 de
# github.com/yyjhao/HTML5-Gomoku. Nao precisa de build; o HTML puxava jQuery 1.8.2 e jQuery Mobile 1.2.0 (MIT) de code.jquery.com
# por http://, e aqui os tres arquivos sao baixados de la uma vez (SHA-256 conferido) e servidos junto do jogo.
#
# Mudancas, todas feitas aqui (cada uma falha se o texto esperado nao existir):
#  - jQuery e jQuery Mobile vendorizados em js/ e style/ (o ajax-loader.gif do jQuery Mobile, que o repositorio nao traz, aponta
#    para o ajax-loader.png que ele traz); o atributo manifest (offline.appcache, arquivo que nao existe) sai;
#  - sai tudo que nao tem origem declarada: as texturas de madeira (woodfloor.jpg, wood.jpg, small-wood.jpg) viram gradientes CSS,
#    as imagens happy.png e sad.png (desenhos de memes de internet) viram os SVG nossos de Builds/gomoku/ e o icon.png, a pasta
#    splash e o splash.xcf (7,5 MB) ficam de fora;
#  - a pagina "About" (links para o site e a loja de extensoes do autor) vira um texto sem links.
# O jogo nao faz outras requisicoes.
#
#   src/FredGames.Bundler/Builds/build-gomoku.sh
#
# Saida: artifacts/build/gomoku-a664ec1/gomoku-a664ec1-site.tar.gz (pasta site/); dois builds seguidos dao os mesmos bytes.
