# Compila o Super Mango (jonathanperis/super-mango-editor, MIT; C11 + raylib 6.2 + Emscripten) do commit 615c748 para o
# fredygames.com, com o Emscripten 6.0.10 (o repositorio fixa o 6.0.13 no CI; EMSCRIPTEN_VERSION=6.0.10 troca so a conferencia).
#
#   src/FredGames.Bundler/Builds/build-super-mango.sh      # precisa de cmake, make e python3
#
# So o jogo: o alvo "make out/super-mango.html" (o editor de fases e o inspetor de debug nao entram; a pagina de debug tambem
# nao). O repositorio ja traz a pagina da build web (web/shell.html, com CSP sem rede externa) e nao tem links para fora, entao
# nao ha patch. A arte e do pacote Super Mango de JuhoSprite (CC BY 4.0), os sons sao gerados em codigo pelo proprio projeto
# (tools/gen_sounds.py) e o texto usa a fonte embutida do raylib. O raylib vem do tarball do commit que vendor/raylib/manifest.json
# fixa (sha256 conferido), passado ao build_raylib.py com --archive.
#
# Saida: artifacts/build/super-mango-615c748/super-mango-615c748-dist.tar.gz + licenses.txt
