# repositorio kitao/pyxel (commit 0ccb8f8), com um patch nosso (mega-wing/no-quit-key.patch: sem tecla de sair, que na
# web so congela a pagina). O .pyxapp original e desempacotado, o patch aplicado e o zip refeito de forma
# deterministica (Builds/pyxapp.py): dois builds seguidos dao o mesmo sha256.
