-"""
-Generic error hierarchy
-Leap/EIP exceptions used for exception handling,
-logging, and notifying user of errors
-during leap operation.
-
-Exception hierarchy
--------------------
-All EIP Errors must inherit from EIPClientError (note: move that to
-a more generic LEAPClientBaseError).
-
-Exception attributes and their meaning/uses
--------------------------------------------
-
-* critical: if True, will abort execution prematurely,
- after attempting any cleaning
- action.
-
-* failfirst: breaks any error_check loop that is examining
- the error queue.
-
-* message: the message that will be used in the __repr__ of the exception.
-
-* usermessage: the message that will be passed to user in ErrorDialogs
- in Qt-land.
-
-TODO:
-
-* EIPClientError:
- Should inherit from LeapException
-
-* gettext / i18n for user messages.
