# Gera o monsterz.pgapp do Monsterz 0.7.1 (Sam Hocevar, codigo e graficos WTFPL; musica de MenTaLguY em dominio
# publico; efeitos sonoros do Barrage, OpenOffice.org, Wesnoth e Kismet, GPL/LGPL) a partir do tarball do Debian
# (monsterz_0.7.1.orig.tar.gz) com os quatro patches do pacote Debian 0.7.1-16 (GPL-2+: correcao de alinhamento, de
# blit, tela de abertura e porta para Python 3) e o nosso monsterz/web.patch (laco assincrono em 12 quadros por
# segundo, saves em /saves, sem o menu de tela cheia, "quit" volta ao menu, sombras sem numpy). A musica .s3m vira
# .ogg aqui (Builds/pygame-music: modrender, da libxmp 4.6.2, e wav2ogg, da libvorbis 1.3.7, em artifacts/tools/;
# mesmos bytes a cada execucao). Zip deterministico (Builds/pgapp.py).
