18# Makefile for generating and updating Unicode-extracted files.
19
20
21# This Makefile is NOT used as part of the GNU libc build.  It needs
22# to be run manually, within the source tree, at Unicode upgrades
23# (change UNICODE_VERSION below), to update ../locales/i18n_ctype ctype
24# information (part of the file is preserved, so don't wipe it all
25# out), and ../charmaps/UTF-8.
26
27# Use make all to generate the files used in the glibc build out of
28# the original Unicode files; make check to verify that they are what
29# we expect; make install to copy them to the location expected by the
30# glibc build; and make clean to remove all generated files.
31
32# We keep a local copy of the downloaded Unicode files, to avoid
33# running afoul of the LGPL corresponding sources requirements, even
34# though it's not clear that they are preferred over the generated
35# files for making modifications.
