How to update:

0) get latest CLDR from http://cldr.unicode.org/index/downloads

1) update $Locales::CLDR_VERSION && $Locales::VERSION

2) build modules out of CLDR, something like this:

   Note: If the DB mods are NOT changing you'll have to update "my $v_offset" in _locales_build_utils.pm && perl -pi -e 's{0\.23}{0.24}g;' t/042.*
   
   ./_build/cldr2locales ../Downloads/
   
../Downloads/ == path to downloaded and extracted CLDR core (should contain 'common/main' dir)

3) do any other changes

4) tidy it all (rt 69971)

  perltidy -b `find lib/Locales/DB -name '*.pm'`
  perltidy -b lib/Locales.pm
  rm `find . -name '*.bak'`

5) perl Makefile.PL && make && make test 

6) RELEASE_TESTING=1 make test 

7) ... make dist && sudo make install
