# Package exception model:
# Here we subclass base Python exception overriding its constructor to
# accomodate error message string as its first parameter and an open
# set of keyword arguments that become exception object attributes.
# While exception object is bubbling up the call stack, intermediate
# exception handlers may insert their own attributes into exception
# object.
