 =head1 DESCRIPTION
 
-Maypole is a Perl web application framework to Java's struts. It is 
-essentially completely abstracted, and so doesn't know anything about
-how to talk to the outside world. C<Apache::MVC> is a mod_perl based
-subclass of Maypole.
-
-To use it, you need to create a package which represents your entire
-application. In our example above, this is the C<BeerDB> package.
-
-This needs to first inherit from C<Apache::MVC>, and then call setup.
-This will give your package an Apache-compatible C<handler> subroutine,
-and then pass any parameters onto the C<setup_database> method of the
-model class. The default model class for Maypole uses L<Class::DBI> to 
-map a database to classes, but this can be changed by messing with the
-configuration. (B<Before> calling setup.)
-
-Next, you should configure your application through the C<config>
-method. Configuration parameters at present are:
-
-=over
-
-=item uri_base
-
-You B<must> specify this; it is the base URI of the application, which
-will be used to construct links.
-
-=item display_tables
-
-If you do not want all of the tables in the database to be accessible,
-then set this to a list of only the ones you want to display
-
-=item rows_per_page
-
-List output is paged if you set this to a positive number of rows.
-
-=back
-
-You should also set up relationships between your classes, such that,
-for instance, calling C<brewery> on a C<BeerDB::Beer> object returns an
-object representing its associated brewery.
-
-For a full example, see the included "beer database" application.
+A mod_perl platform driver for Maypole. Your application can inherit from
+Apache::MVC directly, but it is recommended that you use
+L<Maypole::Application>.
