NAME

       App::Info::Handler::Carp - Use Carp to handle App::Info events

SYNOPSIS

	 use App::Info::Category::FooApp;
	 use App::Info::Handler::Carp;

	 my $carp = App::Info::Handler::Carp->new('carp');
	 my $app = App::Info::Category::FooApp->new( on_info => $carp );

	 # Or...
	 my $app = App::Info::Category::FooApp->new( on_error => 'croak' );

DESCRIPTION

       App::Info::Handler::Carp objects handle App::Info events by passing their messages to Carp functions. This means that if you want errors to
       croak or info messages to carp, you can easily do that. You'll find, however, that App::Info::Handler::Carp is most effective for info and
       error events; unknown and prompt events are better handled by event handlers that know how to prompt users for data. See
       App::Info::Handler::Prompt for an example of that functionality.

       Upon loading, App::Info::Handler::Carp registers itself with App::Info::Handler, setting up a number of strings that can be passed to an
       App::Info concrete subclass constructor. These strings are shortcuts that tell App::Info how to create the proper App::Info::Handler::Carp
       object for handling events. The registered strings are:

       carp
	   Passes the event message to "Carp::carp()".

       warn
	   An alias for "carp".

       croak
	   Passes the event message to "Carp::croak()".

       die An alias for "croak".

       cluck
	   Passes the event message to "Carp::cluck()".

       confess
	   Passes the event message to "Carp::confess()".

INTERFACE

   Constructor
       new

	 my $carp_handler = App::Info::Handler::Carp->new;
	 $carp_handler = App::Info::Handler::Carp->new( level => 'carp' );
	 my $croak_handler = App::Info::Handler::Carp->new( level => 'croak' );

       Constructs a new App::Info::Handler::Carp object and returns it. It can take a single parameterized argument, "level", which can be any one
       of the following values:

       carp
	   Constructs a App::Info::Handler::Carp object that passes the event message to "Carp::carp()".

       warn
	   An alias for "carp".

       croak
	   Constructs a App::Info::Handler::Carp object that passes the event message to "Carp::croak()".

       die An alias for "croak".

       cluck
	   Constructs a App::Info::Handler::Carp object that passes the event message to "Carp::cluck()".

       confess
	   Constructs a App::Info::Handler::Carp object that passes the event message to "Carp::confess()".

       If the "level" parameter is not passed, "new()" will default to creating an App::Info::Handler::Carp object that passes App::Info event
       messages to "Carp::carp()".
