ember-intl-twitch v0.0.21

Fork of Ember-Intl to support our YAML format. This only affects the transformation and bundling part of Ember-Intl. Any of the formatters stuff is loaded through the main Ember-Intl (which has its bundling features disabled because this addon takes care of it).

Differences:

• Transforms Web-Client's Smartling YAML file on app build (transforms meta-properties to normal key/value format)
• Converts translations to Javascript files which are loaded asynchronously. This right locale is set by Rails when rendering index.html.
