# Gera o the-return-of-the-rogue.love de The Return of the Rogue (Bastien Leonard, 7DRL 2022, GPL-3.0) a partir do
# commit 305cbe6 do repositorio, com um patch nosso (publicado junto do fonte):
#   the-return-of-the-rogue/web.patch   comeca em janela (nao em tela cheia); liga os modulos audio, sound e data do
#                                       conf.lua (o love.js quebra com eles desligados: "null function" no start); a escala
#                                       da interface nao liga a tela cheia so para medir a tela; a tela de morte nao tem Quit.
# O .love segue o `make build` do autor: o conteudo de src/ na raiz do zip, mais assets/ e vendor/ (que so tem o
# submodulo vazio do profiler, usado apenas se run_profiler for true), mais o LICENSE.txt. Zip deterministico
# (ordem alfabetica, data fixa, deflate).
