=head1 NAME

Catalyst::Manual::Components - Reuseable components for Catalyst applications

=head1 DESCRIPTION

This section lists the some of the components (and plugins) that are
available to extend the runtime functionality of Catalyst. Most components
are not distributed with Catalyst but should be available from CPAN.
They typically require additional modules from CPAN.

This list may well be outdated by the time you read this, and some
plugins may be deprecated, or, conversely, may now part of core
L<Catalyst>. Be sure to check the Catalyst:: and CatalystX:: namespaces
for additional components, and consult the mailing list (
L<http://dev.catalyst.perl.org/wiki/Support> ) for advice on the current
status or preferred use of your chosen plugin/framework.

=head1 PLUGINS

=head2 L<Catalyst::Plugin::Account::AutoDiscovery>

Provides Account Auto-Discovery for Catalyst.

=head2 L<Catalyst::Plugin::Acme::Scramble>

Implements a potent meme about how easily we can read scrambled text if
the first and last letters remain constant. Operates on text/plain and
text/html served by your Catalyst application.

=head2 L<Catalyst::Plugin::Alarm>

=head2 L<Catalyst::Plugin::AtomPP>

Allows you to dispatch AtomPP methods.

=head2 L<Catalyst::Plugin::AtomServer>

A plugin that implements the necessary bits to make it easy to build an
Atom API server for any Catalyst-based application.

=head2 L<Catalyst::Plugin::Authentication>

An infrastructure plugin for the Catalyst authentication framework. Now the
recommended way to do any form of Authentication.

Note that newer versions of the authentication plugin allow multiple
C<realms>, so that you can authenticate users in different ways in different
parts of your application.

This, however, has involved deprecated all classes in the
C<Catalyst::Plugin::Authentication::Credential::XXX> and
C<Catalyst::Plugin::Authentication::Store::XXX> namespaces.

These plugins are still usable, but they have mostly been replaced with
new modules in the new namespace which will work together.

=head3 Available Credential modules:

=head4 L<Catalyst::Authentication::Credential::AuthTkt>

the body into UTF-8 octets.

=head2 L<Catalyst::Plugin::Unicode>

Disrecommended plugin which tries to autodetect the uft8ness of the output

sub-classes by scanning the underlying table schemas, setting up columns
and primary keys.

=head2 L<Catalyst::Model::CDBI::Plain>

A neutral interface to the C<Class::DBI> module which does not attempt
to automate table setup. It allows the user to manually set up
C<Class::DBI> classes, either by doing so within the Catalyst model

classes.
