# Generates a 64K line output of the form HHHH NNNN, where HHHH is the Unicode
# codepoint in hex, and HHHH is the partition name.  The input file is the
# spec HTML file as prepared by michelsu.  As of this writing, this file can
# be located at http://ie/specs/secure/trident/text/unicode_partitions.htm
#
# The output of this script file can be analyzed by the associate script
# unicodepartition_analyze.pl.  This script will indicate what codepoints are
# multiply defined, and which are not covered.
