Hi,
after composer require mediawiki/cldr 2015.10 or putting the "mediawiki/cldr": "2015.10" in required section of composer.local.json I get the extension extracted into folder mywiki/extensions/Cldr and not into mywiki/extensions/cldr as it is suggested on https://www.mediawiki.org/w/index.php?title=Extension:CLDR&oldid=2000529#Installation. What folder shall be correct?
