# Gera o singularity.pgapp do Endgame: Singularity 1.1 (commit 99729e8 do github.com/singularity/singularity: codigo
# GPL-2+, dados e sons CC BY-SA 3.0, fontes e imagens listados no LICENSE.txt do projeto) com a musica de Max McCracken
# do repositorio singularity/singularity-music (commit 025e269, CC BY-SA 3.0): so quatro faixas (tres de jogo, uma de
# vitoria e uma de derrota). O nosso singularity/web.patch (porta para o navegador): laco de dialogos assincrono (os
# dialogos que a logica do jogo pede no meio de um tick ficam numa fila e abrem em seguida), sem numpy (npshim.py, um
# substituto em Python puro das poucas chamadas que o jogo usa; a mascara de dia e noite do mapa e desenhada em linhas
# com pygame), sem linha de comando nem polib, saves e preferencias em /saves (pelo $HOME e o XDG que o main.py aponta
# para la). Fora do pacote: as traducoes (so ingles), testes, docs, utils e os fontes do Psycle/Renoise.
# Zip deterministico (Builds/pgapp.py).
