-/* This macro creates the following functions:
-
- gdbpy_initialize_{NAME}_event
- Used to add the newly created event type to the gdb module.
-
- and the python type data structure for the event:
-
- struct PyTypeObject {NAME}_event_object_type
-
- NAME is the name of the event.
- PY_PATH is a string representing the module and python name of
- the event.
- PY_NAME a string representing what the event should be called in
- python.
- DOC Python documentation for the new event type
- BASE the base event for this event usually just event_object_type.
- QUAL qualification for the create event usually 'static'
