-Tempest Field Guide to Exceptions
-=================================
-
-
-What are these exceptions?
---------------------------
-
-These exceptions are used by Tempest for covering OpenStack specific exceptional
-cases.
-
-How to add new exceptions?
---------------------------
-
-Each exception-template for inheritance purposes should be added into 'base'
-submodule.
-All other exceptions can be added in two ways:
-- in main module
-- in submodule
-But only in one of the ways. Need to make sure, that new exception is not
-present already.
-
-How to use exceptions?
-----------------------
-
-Any exceptions from this module or its submodules should be used in appropriate
-places to handle exceptional cases.
-Classes from 'base' module should be used only for inheritance.
