This accessor contains the boolean state of the --help, --usage and --?
options (true if any of these options were passed on the command line).
+=method B<print_usage_text>
+
+This method is called internally when the C<help_flag> state is true.
+It prints the text from the C<usage> object (see above) to stdout and then the
+program terminates normally. You can apply a method modification (see
+L<Moose::Manual::MethodModifiers>) if different behaviour is desired, for
+example to include additional text.
+
=method B<meta>
This returns the role meta object.
