They talk about locale-specific files here http://docs.angularjs.org/guide/i18n but don't mention where to get them (the official AngularJS repo doesn't contain them).
So where does one obtain these locale files?
You can also get them with bower:
bower install angular-i18n
It is the official bower distribution that mirrors the files at https://code.angularjs.org/
More info at https://github.com/angular/bower-angular-i18n
Lastest stable version i18n files at here: http://code.angularjs.org/1.0.3/i18n/
You can also find other versions at here: http://code.angularjs.org/
