# This script will update emsdk/bazel/revisions.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.
