# Generates Rust tables that define Unicode "script classes" for the purposes
# of autohinting.
#
# For performance, we want to link various pieces of data by index. For ease of
# modification and to avoid errors, we want to define those links symbolically
# by name. Thus, this script exists which converts symbolic references to
# indices when generating code.
#
# The bottom of this file contains the Rust generation code.
