NAME
       Log::Message::Handlers - Message handlers for Log::Message

SYNOPSIS
           # Implicitly used by Log::Message to serve as handlers for
           # Log::Message::Item objects

           # Create your own file with a package called
           # Log::Message::Handlers to add to the existing ones, or to even
           # overwrite them

           $item->carp;

           $item->trace;

DESCRIPTION
       Log::Message::Handlers provides handlers for
       Log::Message::Item objects.  The handler corresponding to
       the level (see Log::Message::Item manpage for an
       explanation about levels) will be called automatically
       upon storing the error.

       Handlers may also explicitly be called on an
       Log::Message::Item object if one so desires (see the
       Log::Message manpage on how to retrieve the Item objects).

Default Handlers
   log
       Will simply log the error on the stack, and do nothing
       special

   carp
       Will carp (see the Carp manpage) with the error, and add
       the timestamp of when it occurred.

   croak
       Will croak (see the Carp manpage) with the error, and add
       the timestamp of when it occurred.

   cluck
       Will cluck (see the Carp manpage) with the error, and add
       the timestamp of when it occurred.

   confess
       Will confess (see the Carp manpage) with the error, and
       add the timestamp of when it occurred

   die
       Will simply die with the error message of the item

   warn
       Will simply warn with the error message of the item

   trace
       Will provide a traceback of this error item back to the
       first one that occurrent, clucking with every item as it
       comes across it.

Custom Handlers
       If you wish to provide your own handlers, you can simply
       do the following:

       o   Create a file that holds a package by the name of
           "Log::Message::Handlers"

       o   Create subroutines with the same name as the levels
           you wish to handle in the Log::Message module (see the
           Log::Message manpage for explanation on levels)

       o   Require that file in your program, or add it in your
           configuration (see the Log::Message::Config manpage
           for explanation on how to use a config file)

       And that is it, the handler will now be available to
       handle messages for you.

       The arguments a handler may receive are those specified by
       the "extra" key, when storing the message.  See the
       Log::Message manpage for details on the arguments.
