33 The big dilemma for generic bitbake code is what information to give the user
34 when an exception occurs. Any exception inheriting this base exception class
35 has already provided information to the user via some 'fired' message type such as
36 an explicitly fired event using bb.fire, or a bb.error message. If bitbake
37 encounters an exception derived from this class, no backtrace or other information
38 will be given to the user, its assumed the earlier event provided the relevant information.
