=head1 DESCRIPTION
See L<Catalyst::Manual> for more documentation.
Catalyst plugins can be loaded by naming them as arguments to the "use Catalyst" statement.
-Omit the C<Catalyst::Plugin::> prefix from the plugin name,
-so C<Catalyst::Plugin::My::Module> becomes C<My::Module>.
+Omit the C<Catalyst::Plugin::> prefix from the plugin name, i.e.,
+C<Catalyst::Plugin::My::Module> becomes C<My::Module>.
- use Catalyst 'My::Module';
+ use Catalyst qw/My::Module/;
Special flags like -Debug and -Engine can also be specified as arguments when
Catalyst is loaded:
=item -Debug
-enables debug output, i.e.:
-
- use Catalyst '-Debug';
-
-this is equivalent to:
-
- use Catalyst;
- sub debug { 1 }
-
-=item -Dispatcher
-
-Force Catalyst to use a specific dispatcher.
+Enables debug output.
=item -Engine
-Force Catalyst to use a specific engine.
+Forces Catalyst to use a specific engine.
Omit the C<Catalyst::Engine::> prefix of the engine name, i.e.:
- use Catalyst '-Engine=CGI';
+ use Catalyst qw/-Engine=CGI/;
=item -Home
-Force Catalyst to use a specific home directory.
+Forces Catalyst to use a specific home directory.
=item -Log
-Specify log level.
+Specifies log level.
