# Gera o fujo.pgapp do Fujo (Radomir Dopieralski, 2014: codigo e graficos; musica de Joanna Piechowiak; tudo CC BY-SA 4.0)
# a partir do commit 1d5cf99 do repositorio (codeberg.org/osgames/fujo), com o patch fujo/web.patch: porta de Python 2 para
# 3 (xrange, parametros-tupla, divisao inteira, .next(), StringIO, listas no lugar de views), lacos assincronos (pygbag),
# a janela de 480x480 (o original abria 320x200, pequena demais para a arte), save em /saves e "Exit" voltando ao titulo.
# Um arquivo trocado: a fonte PF Ronda Seven Bold (Yusuke Kamiyamane, "All rights reserved" nos metadados) vira a
# Jersey 15 (OFL 1.1, google/fonts), com a OFL junto. Fora do pacote: arquivos de empacotamento do Python 2.
# Zip deterministico (Builds/pgapp.py).
