The big dilemma for generic bitbake code is what information to give the user

when an exception occurs. Any exception inheriting this base exception class

has already provided information to the user via some 'fired' message type such as
|

an explicitly fired event using bb.fire, or a bb.error message. If bitbake
|
|
encounters an exception derived from this class, no backtrace or other information
|
|
will be given to the user, its assumed the earlier event provided the relevant information.
