# Gera o forgotten-angel.pgapp do The Forgotten Angel (Christopher Night e Mary Bichner, PyWeek 19, 2014) a partir do tgz
# original do PyWeek (sha256 abaixo), portado de Python 2 para 3 por um patch (forgotten-angel/web.patch): sintaxe (2to3),
# divisao inteira, sem numpy (transparencia e tingimento das imagens so com o pygame), laco principal assincrono
# (exigido pelo pygbag), sem o botao Quit, saves em /saves, pickles lidos com encoding latin1 e o main.py da raiz. Fora do
# .pgapp: as quatro musicas de Mary Bichner (so "permission given to distribute with this game", nao e licenca livre; o jogo
# fica sem som e o patch tira o credito delas da tela de titulo), as ferramentas de geracao de mapa (Python 2) e o .pyw.
# Zip deterministico (Builds/pgapp.py).
