The only tricky thing with emscripten_wget is that as mentioned in the docs,
http://kripken.github.io/emscripten-site/docs/api_reference/emscripten.h.html#c.emscripten_wget it requires the ASYNCIFY option. It's easier in general to use the async version, emscripten_async_wget, which does not require ASYNCIFY.
