# This script updates all our generated files and exports them to a given
# directory.  This is intended to simplify the process of updating these from
# google3.  After copybara generates a branch for testings, run the following
# from a git clone:
#   git fetch --all
#   git checkout upstream/<copybara branch>
#   ./google3_export_generated_files <ldap>/<citc_workspace>
#
# Note: this is a temporary script and won't be needed once we automatically
# update these.
