# Gera o solarwolf.pgapp do SolarWolf 1.5 (Pete Shinners, LGPL-2.1; graficos de Eero Tamminen, GPL-2, com os fontes
# POV-Ray no tarball) a partir da versao do Debian (solarwolf_1.5+dfsg1.orig.tar.xz) com os patches do pacote
# 1.5+dfsg1-7 que valem para a web (porta para Python 3, musica ao ligar o volume, transparencia das imagens, som no
# inicio, ortografia; o da thread de noticias, o do .desktop e o do comentario do .desktop ficam de fora) e o nosso
# solarwolf/web.patch (laco assincrono, carga dos recursos em quadros em vez de thread, saves em /saves, sem noticias
# nem rede, sem tela cheia e sem "quit"). Fora do pacote: oldsolarfox.png (captura de tela de um jogo do Atari), a
# tela de noticias, dist/, solarwolf-gfx/ e os arquivos de apoio. A musica .xm 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).
