 =head1 DESCRIPTION
 
 This is a universal frontend for mod_perl1, mod_perl2 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.
