# Monta o Tiny Tale (Diego Barbera, 7DRL 2016, MIT) a partir do commit 43cfa39 de github.com/dbrabera/tiny-tale, sem etapa de
# build do autor. Mudanca em tiny-tale/no-external.patch: o rot.js 0.6.0 (BSD-3) deixa de vir do cdnjs e vai junto
# (mesmo arquivo, sha256 conferido) e a tag duplicada de Log.js sai.
# O index.html ganha tambem <meta charset="utf-8">: sem ele o navegador le o texto UTF-8 como Latin-1.
#
#   src/FredGames.Bundler/Builds/build-tiny-tale.sh
#
# Saida: artifacts/build/tiny-tale-43cfa39/tiny-tale-43cfa39-dist.tar.gz (pasta dist/; igual em dois builds seguidos).
