TLDR: There is a field in called EMSCRIPTEN_ROOT in the config file which in theory can be used by external tools to find the "active" emscripten. I'm proposing to remove it.
--- Maintaining this field has a cost and it can get out of sync with the emscripten you are actually using. Imagine you run `emcc` and if parses the config file and finds EMSCRIPTEN_ROOT pointing to different version of emscripten. The two current users of EMSCRIPTEN_ROOT that I know of are the scons support: https://github.com/kripken/emscripten/blob/incoming/tools/scons/site_scons/site_tools/emscripten/emscripten.py And ammo.js: https://github.com/kripken/ammo.js/blob/master/make.py#L17 In both of these cases a better solution would be either: 1) looks for `emcc` in the $PATH 2) check for EMSCRIPTEN_ROOT in the environment. Parsing the config file is also a rather brittle solution, and prevents us from iterating on the config file format and how its parses. It also uses python's `eval` which is nasty.
