the accessors. The accessors in the following subsections are added.

=head2 B<< no_routes >>

boolean flag to avoid routes generation upon plugin import. Used during
the L</BUILD> process. Defaults to C<0>, meaning that the routes will be

L</install_get_route>).

the I<verification token> required by FaceBook to make sure your settings
are accepted by your bot. You MUST set this or it will complain loudly
