  # update_glslang_binary.py:
  #   Helper script to update the version of glslang in cloud storage.
  #   This glslang is used to precompile Vulkan shaders. This script builds
  #   glslang and uploads it to the bucket for Windows or Linux. It
  #   currently only works on Windows and Linux. It also will update the
  #   hashes stored in the tree. For more info see README.md in this folder.
