# 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 in this folder.
