# Gera o pathological.pgapp do Pathological 1.1.3 (John-Paul Gignac, GPL-2.0-ou-posterior; trilha de Matthias Le Bidan,
# logo de Carrie Bloomfield, efeitos tambem do CannonSmash e do Gnibbles, GPL) a partir do tarball do Debian
# (pathological_1.1.3.orig.tar.gz) com seis patches do pacote Debian 1.1.3-18 (GPL-2+: pontuacao, sem placa de som,
# pygame 1.8.1, musica em ogg, porta para Python 3) e o nosso pathological/web.patch (lacos assincronos, saves em /saves,
# tela cheia a cargo da pagina, "Quit Game" volta ao menu). As duas musicas .xm viram .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).
# O fonte vai de ISO-8859-1 para UTF-8 (o pygbag nao le a linha de coding). Zip deterministico (Builds/pgapp.py).
