# Gera o 20000-light-years-into-space.pgapp do 20,000 Light-Years Into Space 1.5.2 (Jack Whitham, 2006-2021, GPL-2; graficos de Cris
# Grada tambem GPL-2; fonte Bitstream Vera; foto lunar da Apollo 15, NASA; icone do XSane, GPL) a partir do tarball do Debian
# (lightyears_1.5.2.orig.tar.gz, o mesmo do repositorio do autor na versao 1.5.2) com o nosso 20000-light-years-into-space/web.patch
# (lacos assincronos, sem busca de novidades nem navegador, saves em /saves, sem "Exit": o menu recomeca).
# Tres texturas (006metal, greenrust, rivets), cujas originais vinham do site Accustudio ("livre de direitos" so pelos termos
# do site), e o som do terremoto, cuja original dizia "dominio publico" sem fonte verificavel, sao trocados por arquivos que
# o nosso 20000-light-years-into-space/gen-assets.py desenha e sintetiza (Pillow em artifacts/tools/venv; o som vira .ogg com o
# wav2ogg de Builds/pygame-music). Fora do pacote: testes, empacotamento, o manual em PDF e a foto de exemplo.
# Zip deterministico (Builds/pgapp.py).
