# Monta o Terminus (aventura de texto que ensina a linha de comando do Unix, de luffah, a partir do jogo de Michele Pratusevich e Shawn
# Conrad, com a arte de Emma Tolley; GPL-2.0, com imagens MIT e musicas/sons CC0, CC-BY e CC-BY-SA) a partir do commit 52e6433 de
# github.com/luffah/Terminus. O proprio sistema de build do autor (tools/build/build, Python) gera game.js e os dialogos; ele precisa de:
#  - o submodulo tools/lib/python3/ogaget (github.com/luffah/ogaget no commit e253684, que o tarball do GitHub nao traz) e do polib 1.2.0
#    (PyPI, so Python), ambos conferidos pelo sha256;
#  - o "cp -rT" do GNU, que no macOS nao existe: Builds/terminus/cp-shim.sh o traduz para "cp -R origem/. destino" (so no PATH do build);
#  - as musicas e os sons, que o "make fetch_resources" do autor baixa do OpenGameArt: aqui cada arquivo e baixado da URL do .txt do
#    recurso e conferido pelo sha256 (Builds/terminus/resources.tsv; os dois zips grandes so fornecem 4 arquivos); char.wav e grl.wav
#    (vozes do texto, do autor) nao estao no repositorio, entao Builds/terminus/beeps.py gera dois bipes nossos com o mesmo nome.
# O ingles do autor esta incompleto: terminus/en-extra.json (283 textos da interface e do jogo, mais 6 que faltavam nos dois idiomas; traducao nossa) completa o dialog.en.js.
# Nao usa Node nem npm (o "-html" do autor, que gera um HTML unico, precisa deles; aqui a pagina e montada como no servidor de
# desenvolvimento do autor). Mudancas nossas: index.html em ingles (dialog.en.js), com uma Content-Security-Policy e sem as
# imagens de teste; so os arquivos de css do formato woff/woff2; o engine fica em js.engine/ (o index.html do autor o espera la).
#
#   src/FredGames.Bundler/Builds/build-terminus.sh
#
# Saida: artifacts/build/terminus-52e6433/{terminus-52e6433-dist.tar.gz,licenses.txt}; o tar.gz tem que sair igual em dois builds.
