  18 # Makefile for generating and updating Unicode-extracted files.

  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
  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.
