# Prepara os jogos de dtsudo (Tux Planet Speedrun Any%, Tux Planet 2, Symbiosis Chess, Queen Sac, Chess Comp Stomp with Hacks,
# DT Danmaku 2). Sao paginas HTML/JavaScript prontas no repositorio (C# transpilado com Bridge.NET, ou TypeScript compilado),
# entao nada e compilado: o script baixa o tarball do commit (sha256 conferido), escolhe os arquivos do jogo, aplica as mudancas
# de dtsudo-games/patch.py e empacota tudo num tar.gz deterministico.
#
# Mudancas (patch.py): CSP no index.html (nenhuma requisicao fora da pasta); o link para o GitHub do autor nao faz nada; os saves
# do navegador (localStorage, mesma origem para todos os jogos) ganham o prefixo "<slug>:"; no Tux Planet Speedrun, a frase do
# texto de instrucoes que xinga os "devs" fica neutra. Fora do pacote: o app Electron (main.js, package*.json, .desktop...), o
# codigo-fonte C#/TypeScript (continua no tarball de fonte) e, nos jogos de xadrez, o stockfishSourceCode.zip
# (vai em "sources" do bundle.yaml, ao lado do binario). O index.html e a pagina do jogo renomeada.
#
#   src/FredGames.Bundler/Builds/build-dtsudo-games.sh [slug ...]      (sem argumento: todos)
#
# Saida: artifacts/build/dtsudo-<slug>-<commit7>/{<slug>-<commit7>-dist.tar.gz,licenses.txt,LICENSE.txt}; o tar.gz tem que
# sair igual em dois builds seguidos.
