# Gera o which-way-is-up.pgapp do Which Way Is Up? (Olli Etuaho, bifurcacao 2.0.0pre de Daniel Foerster/pydsigner,
# GPL-2.0 no codigo e CC BY 3.0 no resto) a partir do commit 53a0dd4 do repositorio, com o patch web.patch: porta de
# Python 2 para 3 (imports, has_key, print >>, divisao inteira, None > 0), os lacos viram assincronos (pygbag), o
# leitor de TMX do pytmx vira uma funcao de 20 linhas (so o primeiro mundo usa TMX), a pasta de saves passa a ser
# /saves quando ela existe (a pagina a guarda no IndexedDB) e os menus de tela cheia, personagem e mundo saem (os
# outros dois mundos dessa versao nao tem todas as imagens). O script tira do pacote os arquivos de desenvolvimento
# (run_game.py, .bat, .ico, setup.py com py2exe, stubs que nao compilam) e poe o main.py de entrada.
# Zip deterministico (Builds/pgapp.py).
