Bugfixes
~~~~~~~~

* CLDR: The lxml library is no longer used for CLDR importing, so it should not cause strange failures either. Thanks to aronbierbaum for the bug report and jtwang for the fix. (:gh:`393`)
* CLI: Every last single CLI usage regression should now be gone, and both distutils and stand-alone CLIs should work as they have in the past. Thanks to paxswill and ajaeger for bug reports. (:gh:`389`)
