[Kimchi-devel] [PATCH 1/8] refactor exception: Create a common Exception to translate error messages
Aline Manera

Sun Feb 9 22:47:55 UTC 2014
From: Aline Manera <alinefm at br.ibm.com>
KimchiException will be the base for all other Exception types in Kimchi
It will translate the error message before raising it.
Then UI can use the message directly. That way we avoid duplicating messages
on UI and backend.
Also add i18n.py which will contain all the backend messages to be translated.
