  Message : Automatically call flex/bison if necessary ANGLE translator's parser code generation is changed to use the binaries of flex/bison stored in the cloud. scripts/run_code_generation.py now automatically runs these files if the input files change. Bug: angleproject:3419 Change-Id: Icce4247f93b27baf8ee12dbb16112fa2cc98c111 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1940572 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>

  # update_flex_bison_binaries.py:
  #   Helper script to update the version of flex and bison in cloud storage.
  #   These binaries are used to generate the ANGLE translator's lexer and parser.
  #   This script relies on flex and bison binaries to be externally built which
  #   is expected to be a rare operation. 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.
