# Makefile for generating and updating Unicode-extracted files.
# This Makefile is NOT used as part of the GNU libc build. It needs
# to be run manually, within the source tree, at Unicode upgrades
# (change UNICODE_VERSION below), to update ../locales/i18n ctype
# information (part of the file is preserved, so don't wipe it all
# out), and ../charmaps/UTF-8.
# Use make all to generate the files used in the glibc build out of
# the original Unicode files; make check to verify that they are what
# we expect; make install to copy them to the location expected by the
# glibc build; and make clean to remove all generated files.
# We keep a local copy of the downloaded Unicode files, to avoid
# running afoul of the LGPL corresponding sources requirements, even
# though it's not clear that they are preferred over the generated
# files for making modifications.
