8#   Helper script to update the version of flex and bison in cloud storage.
9#   These binaries are used to generate the ANGLE translator's lexer and parser.
10#   This script relies on flex and bison binaries to be externally built which
11#   is expected to be a rare operation. It currently only works on Windows and
12#   Linux. It also will update the hashes stored in the tree. For more info see
13#   README.md in this folder.
