# Monta o XiangQi Wizard Light (GPL-2.0-or-later, Morning Yellow / xqbase.com; xadrez chines em JavaScript) a partir
# da pasta JavaScript/ do commit 6221733 de github.com/xqbase/xqwlight. O motor (position.js, search.js, book.js,
# cchess.js) vai sem mudanca; so o board.js muda (Builds/xqwlight/):
#   - os textos em chines (mensagens de fim de partida, em GBK) passam para o ingles e saem por window.xqStatus;
#   - as imagens e os sons do repositorio nao tem origem declarada: o tabuleiro e as pecas sao desenhos nossos (SVG
#     gerados por Builds/xqwlight/gen-images.py, pecas com as letras K A E H R C P) e nao ha som;
#   - as medidas de style.left/top/width/height ganham "px" (a pagina original roda em quirks mode, a nossa nao).
# A pagina (index.html, app.js, app.css) e nossa, com a interface em ingles; app.js e a logica do index.htm do projeto.
#
#   src/FredGames.Bundler/Builds/build-xqwlight.sh
#
# Saida: artifacts/build/xqwlight-6221733/xqwlight-6221733-site.tar.gz (pasta site/); dois builds seguidos dao os
# mesmos bytes.
