# Gera o duckmaze.pgapp do Duckmaze 0.2 (Andy Balaam, 2006-2007, GPL-2-ou-posterior; os graficos sao desenhados no codigo e as
# telas de titulo sao dele) a partir da etiqueta 0.2 do repositorio do autor (codeberg.org/andybalaam/duckmaze, importado do
# SVN do SourceForge; commit 7bc7f1b, 10/11/2007, o mesmo da versao 0.2 publicada: sem a musica do fork de 2014), com o nosso
# duckmaze/web.patch: porta de Python 2 para 3, lacos assincronos e timers proprios (pygbag nao tem pygame.event.wait nem
# set_timer), saves em /saves, sem o editor de fases (as fases dele nao podem ser jogadas na 0.2), sem os itens de som e de sair.
# Fora do pacote: o editor, as imagens e o executavel para GP2X, o material de empacotamento e a pagina do projeto.
# Zip deterministico (Builds/pgapp.py).
