# This file builds the js components using emscripten. You normally don't need
# to run this, as the builds are bundled in the repo in bin/. Running this is
# useful if you are a developer and want to update those builds.
#
# Usage: build-js.sh
# Usage: EMSCRIPTEN=path/to/emscripten build-js.sh # explicit emscripten dir
#
# Emscripten's em++ and tools/webidl_binder.py will be accessed through the
# env var EMSCRIPTEN, e.g. ${EMSCRIPTEN}/em++
#
# You can get emscripten from
# http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
