-- exception handler test module
--
--
-- To avoid this from crashing the module will startup in inactive mode.
-- to make specific errors happen you need to cause them by following
-- chat command:
--
-- exceptiontest <location> <errortype>
--
-- location has to be one of:
-- * mapgen: cause in next on_generate call
-- * entity_step: spawn a entity and make it do error in on_step
-- * globalstep: do error in next globalstep
-- * immediate: cause right in chat handler
--
-- errortypes defined are:
-- * segv: make sigsegv happen
-- * zerodivision: cause a division by zero to happen
-- * exception: throw an exception
