The next attribute option is new, though: the C<predicate> option.
This option creates a method which can be used to check whether
-a given slot (in this case C<parent>) contains a defined value. In
+a given slot (in this case C<parent>) has been initialized. In
this case it will create a method called C<has_parent>. Quite simple,
and quite handy too.
Now, as with all the other recipes, you can go about using
B<BinaryTree> like any other Perl 5 class. A more detailed example of its
-usage can be found in F<t/003_recipe.t>.
+usage can be found in F<t/000_recipes/003_recipe.t>.
