<title>Initialising and Finishing using the Library</title>

<para>Raptor requires initialising a raptor_world object before using
any of the classes which take the world object as an argument in
their constructors.  The function to make the world object is
raptor_new_world() and the destructor raptor_free_world().
<programlisting>
  raptor_world* world;
  world = raptor_new_world();
  ...
  raptor_free_world(world);
</programlisting>
</para>
