 =head1 NAME
 
-Maypole::Application - Maypole Universal Frontend
+Maypole::Application - Universal Maypole Frontend
 
 =head1 SYNOPSIS
 
     use Maypole::Application;
 
+    use Maypole::Application qw(Config::YAML);
+
+    use Maypole::Application qw(-Debug Config::YAML -Setup);
+
+    use Maypole::Application qw(Config::YAML Loader -Setup -Debug);
+
+    use Maypole::Application qw(-Debug2 MasonX AutoUntaint);
+
 =head1 DESCRIPTION
 
-This is a universal frontend for mod_perl1, mod_perl2 and CGI.
+This is a universal frontend for mod_perl1, mod_perl2, HTML::Mason and CGI.
 
-You can omit the Maypole:: prefix from plugins.
-So Maypole::Config::YAML becomes Config::YAML.
+You can omit the Maypole::Plugin:: prefix from plugins.
+So Maypole::Plugin::Config::YAML becomes Config::YAML.
 
     use Maypole::Application qw(Config::YAML);
 
+You can also set special flags like -Setup and -Debug.
+
+    use Maypole::Application qw(-Debug Config::YAML -Setup);
+
+The position of plugins and flags in the chain is important,
+because they are loaded/executed in the same order they appear.
+
+=head2 -Setup
+
+    use Maypole::Application qw(-Setup);
+
+is equivalent to
+
+    use Maypole::Application;
+    MyApp->setup;
+
+Note that no options are passed to C<setup()>. You must ensure that the
+required model config parameters are set in C<MyApp-E<gt>config>. See
+L<Maypole::Config> for more information.
+
+=head2 -Debug
+
+    use Maypole::Application qw(-Debug);
+
+is equivalent to
+
+    use Maypole::Application;
+    sub debug { 1 }
+
+You can specify a higher debug level by saying C<-Debug2> etc.
