=head2 What about Maypole::Application - loading plugins\r
\r
-The main job of L<Maypole::Application> is to insert the plugins into the \r
-hierarchy. It ensures that L<BeerDB> inherits from the first plugin, which \r
-inherits from the next, etc., until the last plugin inherits from the frontend. \r
-\r
-It is also the responsibility of L<Maypole::Application> to decide which \r
-frontend to use. \r
+The main job of L<Maypole::Application> is to insert the plugins into the\r
+hierarchy. It is also the responsibility of L<Maypole::Application> to decide\r
+which frontend to use. It builds the list of plugins, then pushes them onto the\r
+driver's C<@ISA>, then pushes the frontend onto the end of the driver's C<@ISA>.\r
+So method lookup first searches all the plugins, before searching the frontend\r
+and finally L<Maypole> itself.\r
\r
From Maypole 2.11, L<Maypole::Application> makes no appearance in the\r
inheritance structure of a Maypole application. (In prior versions,\r
L<Maypole::Application> would make itself inherit the plugins, and then insert\r
itself in the hierarchy, but this was unnecessary).\r
\r
-The order of inheritance is the same as the order in which plugins are supplied \r
-in the C<use Maypole::Application> statement. \r

=head2 Who builds the model?\r
\r
First, remember we are talking about the standard, unmodified Maypole here. \r
