# Gera o eight-bit-passage.pgapp do The Eight Bit Passage (Christopher Night, PyWeek 18, 2014) a partir do tgz original do
# PyWeek (versao 2, sha256 abaixo), portado de Python 2 para 3 por um patch (eight-bit-passage/web.patch): sintaxe (2to3),
# divisao inteira, laco principal assincrono (exigido pelo pygbag; Q no menu de pausa recomeca em vez de sair), save em
# /saves, sem o ruido por pixel das imagens (lowres) e o main.py da raiz. Fora do .pgapp: o tgz da versao 1 que vinha
# dentro, as capturas de tela e o .pyw. Zip deterministico (Builds/pgapp.py).
