.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class is a subclass of CLI::Framework::Command.  It defines
\&\*(L"metacommands\*(R", 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.
.PP
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
\&\f(CW\*(C`CLI::Framework::Command\*(C'\fR.
