Hi, guys, I submit a script for checking i18n message for quantum project. https://review.openstack.org/#/c/17201/ That script can find message that need i18n. Although it only can ensure LOG.xxx message must be i18n, and only show warn for other message. But it might be better than none. And it might be useful for other openstack project. So send a note at here. Welcome any suggestion! Thanks! Alex
