"""Prepara os recursos do The Burdened Raid para a edicao web (dentro do projeto extraido):
  - troca a fonte bitmap core/assets/font.fnt/.png (exportada da Alagard, que nao tem licenca registrada) por uma gerada
    da Jacquard 12 (SIL OFL 1.1), mesmo nome de arquivo e mesmos caracteres (BMFont em texto + pagina PNG);
  - apaga o badlogic.jpg (imagem padrao do libGDX que o jogo nao usa) e os arquivos do SoundManager2 e da pagina
    antiga em html/webapp (o libGDX atual nao usa o SoundManager2).
Uso: fix-assets.py <raiz do projeto> <Jacquard12.ttf>"""
