# Gera o gatemender.pgapp do Gatemender 0.2 (Erik Letson, Librejam 2020) a partir do zip do autor (hmagellan.com,
# hoje fora do ar; a copia do Internet Archive e identica byte a byte, sha256 abaixo), com um patch
# (gatemender/web.patch): so o laco principal assincrono (exigido pelo pygbag). O jogo grava os recordes em hs.json
# mas nunca os mostra, entao nao ha o que persistir. Fora do .pgapp: os .swp de editor e os .pyc do zip. Zip
# deterministico (Builds/pgapp.py).
