won't remove the C<class_has()> function. To do that you must include
C<no MooseX::ClassAttribute> as well.
+If you want to use this module to create class attributes in I<other>
+classes, you can call the C<process_class_attribute()> function like
+this:
+
+ MooseX::ClassAttribute::process_class_attribute( $package, ... );
+
+The first argument is the package which will have the class attribute,
+and the remaining arguments are the same as those passed to
+C<class_has()>.
