# Gera o uslingborg-defense.pgapp do Uslingborg Defense (Christopher Night, PyWeek 14, 2011) a partir do zip original do
# PyWeek (sha256 abaixo), portado de Python 2 para 3 por um patch (uslingborg-defense/web.patch): sintaxe (2to3), divisao
# inteira, sem numpy (a textura do mapa e o tingimento das imagens sao feitos so com o pygame), laco principal
# assincrono (exigido pygbag), Esc nao sai, sem a fala (os .ogg de fala nao estao no pacote) e o main.py da raiz.
# Fora do .pgapp: "Lame Monster Party" de Paul and Storm (CC BY-NC-SA, nao serve; a fase final usa outra faixa do
# proprio jogo), a captura de tela e o .pyw. Zip deterministico (Builds/pgapp.py).
