# Tk), teclas e controles escolhidos por dialogos sem laco proprio, dados lidos onde estao (o original os copia para uma
# pasta temporaria a cada execucao), saves em /saves. Para o jogo caber no navegador:
#  - sem a fonte Takao P Gothic + IPA Font License (6 MB, so serve as traducoes japonesas), sem as traducoes (.po), sem
#    as fontes dos sprites do Tux e do som da mola (sources/) e sem splat.wav e wood.wav (nao usados);
#  - a musica (24 MB, ~150 kbps) e recodificada a ~70 kbps com Builds/retux/recode-music.py (decodifica com o pygame-ce
#    e codifica com o libvorbis de Builds/pygame-music/);
#  - explosion.wav (sem autor nem licenca no LICENSES) vira o efeito gerado por Builds/retux/explosion.py (CC0, nosso).
