 ---------------------
 
 Extensions are responsible to provide/include their own dependencies or create companion modules/bundles to do so.

+Translation Provision Responsibility
+------------------------------------

+####Core:
+The core will be released with only English. Translations will be provided as secondary downloads.
+
+####Third Party Extensions:
+Third party extensions should endeavor to include all available translations within their release. A quick release cycle should be used in order to quickly make available new translations and small bug fixes as they become available. While a contributor may make an extension translation available as an additional download, this is discouraged and should be included in the main package as soon as the next release.
