CLI::Framework::Command::Meta - Represent "metacommands" (app-aware
This class is a subclass of CLI::Framework::Command. It defines
"metacommands", commands that are application-aware (and thus,
implicitly aware of all other commands registered within the application).
Metacommands have methods that set and retrieve a reference to the application
within which they are running.
This class exists as a separate class because, with few exceptions, commands
should be independent of the application they are associated with and should
not affect that application. Metacommands represent the exception to that
rule. In the exceptional cases, your command will inherit from this one
instead of "CLI::Framework::Command".
See tutorial advice on this topic.
Retrieve or set the application object associated with a metacommand object.
$app = $command->get_app();
$command->set_app( $app );
