# Gera o seismic-afterburner.love do Seismic Afterburner (rominou66, AGPL-3.0) a partir do commit dda3128 do
# repositorio, com um patch nosso (publicado junto do fonte):
#   seismic-afterburner/no-quit.patch   a tecla Esc deixa de fechar o jogo (no navegador so sobraria um canvas preto).
# O .love e um zip deterministico (ordem alfabetica, data fixa, deflate) com main.lua,
# conf.lua, src/, assets/, LICENSE e credits; ficam de fora o que o jogo nao carrega: assets/map (arquivos do
# Tiled; o mapa vem de src/level_data.lua), tres musicas nao usadas (Mars, Venus, Intro Jingle), os .ase
# (projetos do editor), capturas de tela, README e a pasta makelove-build (binarios).
