This module provides a common base class for all exceptions
which are related to user or configuration errors. These exceptions
should be caught and reported to the user using a meaningful message
instead of a stacktrace.
When handling errors in KAS, never return directly using `sys.exit`,
but instead throw an exception derived from :class:`KasUserError` (for user
errors), or one derived from `Exception` for internal errors. These
are then handled centrally, mapped to correct return codes and pretty
printed.
