Hi,
I would like to offer my image and my support as a maintainer for this image which is placed under:

• https://github.com/trzecieu/emscripten-docker
• https://hub.docker.com/r/trzeci/emscripten
• https://hub.docker.com/r/trzeci/emscripten-slim

I spent pretty decent amount of spare time maintaining it and optimizing the image size (which at the moment is ~160MB for Emscripten + base tools) and I think that it will be much more trustworthy if we could offer it from an official source.
