# Monta o Super Overachiever 42000 Deluxe (Artur "suve" Iwicki, Ludum Dare 42; codigo AGPL-3.0, o resto CC BY-SA 4.0) a partir do
# commit 9b4d555 de github.com/suve/LD42, repetindo o que o Makefile do autor faz, sem php, imagemagick nem pngcrush:
#   - src/*.js: o mesmo sed do Makefile (caminhos ../gfx/ e ../sfx/ viram relativos);
#   - gfx/*.png: o "convert -transparent '#209C00' -transparent '#FF678B'" vira Pillow (as duas cores viram transparentes), sem o pngcrush;
#   - map/*.png: Builds/super-overachiever/map-to-js.py, porte em Python do src/map-to-js.php;
#   - index.html, style.css e sfx/*.wav copiados.
# As licencas (LICENCE-AGPL-v3.txt e LICENCE-CC-BY-SA-v4.txt) vao junto na pasta do jogo. Precisa do Python de artifacts/tools/venv (Pillow).
#
#   src/FredGames.Bundler/Builds/build-super-overachiever.sh
#
# Saida: artifacts/build/super-overachiever-9b4d555/dist.tar.gz (pasta dist/); sai igual em dois builds seguidos.
