# Gera a pagina de jogos de Bitsy (o exportador de HTML unico do motor Bitsy, MIT, ja embutido na pagina de cada jogo) dos
# repositorios dos proprios autores: Left Undetected (mildmojo, GGJ 2018), The King Is Back (Victor Enrique) e A Cozy Winterwalk
# (Rick / tinyworlds), todos MIT. O HTML vem do commit pinado e conferido pelo sha256; as mudancas nossas ficam em bitsy/make.py:
#   - Left Undetected: sem o rodape com links (repositorio, itch, Twitter e site do autor) e sem o @ e o site do autor na tela final;
#   - A Cozy Winterwalk: sem a trilha de fundo, que o jogo tocava de um video do YouTube (script e iframe externos);
#   - CSP que bloqueia qualquer requisicao fora da pagina.
# O texto da licenca do Bitsy (LICENSE.md de le-doux/bitsy no commit ee412fa) sai junto, para o LICENSE.txt.
#
#   src/FredGames.Bundler/Builds/build-bitsy-games.sh
#
# Saida: artifacts/build/bitsy-games/<slug>.html (+ <slug>.bitsydata onde houver, <slug>.LICENSE e bitsy.LICENSE). Roda duas vezes com o mesmo resultado.
