# This script will update emsdk/bazel/revisons.bzl to the latest version of
# emscripten. It reads emsdk/emscripten-releases-tags.json to get the latest
# version number. Then, it downloads the prebuilts for that version and computes
# the sha256sum for the archive. It then puts all this information into the
# emsdk/bazel/revisions.bzl file.
