Fuego + WASM = fuego.js?

[klueq]

It would be interesting to compile Fuego with Emscripten into a WASM library and then use in JS web apps. It could be a in-the-browser Go bot or a tool to analyze games or tsumegos.

I gave it a try, installed boost and sys headers, but still emcc gives way too many cryptic errors:

emcc -O3  \
    -s WASM=1 \
    -I /usr/include \
    -I smartgame \
    smartgame/*.cpp
