# Compila o Juicefruit Orchard (jogo de fazenda de suco de Michael Pauley/reheated, Ludum Dare 45; codigo, arte e
# musica CC0 1.0; fonte m5x7 de Daniel Linssen, CC0) a partir do commit e9d2410 de github.com/reheated/ph, onde o
# jogo vive em juicefruit/. Faz o mesmo que o "ph build" do autor: o TypeScript do jogo e da biblioteca ph
# (tsc 5.9.3, uma saida so, sem source map) vira game.js, os recursos viram game.dat (Builds/juicefruit-orchard/
# bundle.mjs reproduz o formato) e o template vira o index.html. Unica mudanca: uma CSP no index.html (nada sai do
# site). O codigo do jogo nao e alterado.
#
#   src/FredGames.Bundler/Builds/build-juicefruit-orchard.sh
#
# Saida: artifacts/build/juicefruit-orchard-e9d2410/{juicefruit-orchard-e9d2410-dist.tar.gz,licenses.txt}; o tar.gz
# (pasta dist/) sai igual em dois builds seguidos.
