Include, one cannot live without the other. The use case
must include another use case. For example when you create
an order you always must verify name etc.
Extend, one can live without the other only some instances
the use case will extend to another use case to do some
stuff. For example, you can create an order but if the
order is for a new customer you possible have to do
additional check which you do not have to do for existing
customers. In that case you can have an extend use case.
