# Compila o Outlaw Mayor Panic! (01010111 / Will Blanton, Ludum Dare 41, 2018; codigo, arte e musica MIT;
# github.com/01010111/LD41) para a web (HTML5) com o HaxeFlixel, com as mesmas ferramentas pinadas do Plankter (Haxe
# 4.3.6, Lime 8.1.2, OpenFL 9.3.3, HaxeFlixel 5.8.0, flixel-addons 3.2.3; ver build-plankter.sh, que as instala) e o
# zerolib 0.2.3 (MIT, lib.haxe.org). O jogo usou um zerolib de abril de 2018, que nunca foi publicado no haxelib (a
# primeira versao la e de julho de 2018); o 0.2.3 e a mais antiga e traz quase tudo, e o que falta (ZState,
# ZPlayerController, ZBaseController) esta em outlaw-mayor-panic/web.patch. O ndll do Lime so existe para x86_64:
# em Apple Silicon roda sob Rosetta.
#
# Mudancas (o repositorio do commit pinado e o que mudamos esta em outlaw-mayor-panic/web.patch):
#   - o texto de fim de jogo "GO FRICK URSELF" (um insulto disfarcado) sai da lista de frases;
#   - classes do zerolib de 2018 que o jogo usa e o 0.2.3 nao tem, escritas de novo (shim/), e tirados os imports que
#     nao eram usados; o findPath do HaxeFlixel 5 recebe o simplificador como um enum (antes eram dois Bool "false");
#   - a fonte padrao do HaxeFlixel, "Nokia Cellphone FC Small", vira a Jersey 20 (SIL OFL 1.1), como no Plankter;
#   - uma Content-Security-Policy no index.html (nenhuma conexao fora desta origem);
#   - a versao do cache de assets, um numero aleatorio que o Lime grava no LD41.js, vira 1 (build reprodutivel).
