In general custom events are not supported. There are however occasions where
you might want to write a custom event type that results in \s-1TAP\s0 output. In
order to do this you use the \f(CW\*(C`register_event()\*(C'\fR class method.

.IX Subsection "EVENT METHODS"
All these methods require the event itself. Optionally they can all except a
test number.
.PP
All methods return a list of array-refs. Each array-ref will have 2 items, the
first is an integer identifying an output handle, the second is a string that
should be written to the handle.
