"""Convert CLDR data to qLocaleXML
The CLDR data can be downloaded from CLDR_, which has a sub-directory
for each version; you need the ``core.zip`` file for your version of
choice (typically the latest). This script has had updates to cope up
to v29; for later versions, we may need adaptations. Unpack the
downloaded ``core.zip`` and check it has a common/main/ sub-directory:
pass the path of that sub-directory to this script as its single
command-line argument. Save its standard output (but not error) to a
file for later processing by ``./qlocalexml2cpp.py``
When you update the CLDR data, be sure to also update
src/corelib/tools/qt_attribution.json's entry for unicode-cldr.
