# Gera o Main.swf do Alien Egg Farm (Andras Nemeth, MIT, github.com/cu2/Alien-Egg-Farm, commit dd5fc4e) com a
# fonte trocada: o Flixel 2.35 embute a "Nokia Cellphone FC" (freeware, sem licenca de redistribuicao); o
# alien-egg-farm/patch-font.py reescreve essa tag com a Silkscreen (OFL 1.1) e deixa o resto do SWF como o autor
# publicou (sem recompilar).
