# Compila o Cultivation do fredygames.com: o jogo de jardinagem em comunidade de Jason Rohrer (2007,
# dominio publico) em WebAssembly, com o Emscripten 6.0.10. Este script e os arquivos de
# Builds/minorgems-web/ fazem parte do codigo-fonte publicado junto do jogo.
#
#   source <emsdk>/emsdk_env.sh      # emsdk install 6.0.10 && emsdk activate 6.0.10
#   src/FredGames.Bundler/Builds/build-cultivation.sh
#
# Fonte: o tarball upstream do Debian (cultivation_9+dfsg1.orig.tar.gz: o codigo da versao 9 do autor,
# com a biblioteca minorGems dele, sem a pasta do portaudio), conferido pelo SHA-256. O jogo nao leva
# nenhuma mudanca de codigo: o que o Emscripten nao tem fica nos arquivos de Builds/minorgems-web/
# (GLUT que falta, portaudio sobre SDL2 audio, GLU e glBegin/glEnd, sleep, ver glut-compat.h).
#
# Saida: artifacts/build/cultivation-9/cultivation.{js,wasm,data}, que o bundle.yaml confere pelo SHA-256.
