714 Helpers are classes that provide two methods.
716 * mk_compclass - creates the Component class
717 * mk_comptest - creates the Component test
719 So when you call C<bin/create view MyView TT>, create would try to execute
720 Catalyst::Helper::View::TT->mk_compclass and
721 Catalyst::Helper::View::TT->mk_comptest.
723 See L<Catalyst::Helper::View::TT> and L<Catalyst::Helper::Model::CDBI> for
726 All helper classes should be under one of the following namespaces.
728 Catalyst::Helper::Model::
729 Catalyst::Helper::View::
730 Catalyst::Helper::Controller::
