NAME

       MooseX::App::Message::Envelope - Message presented to the user

DESCRIPTION

       Whenever MooseX::App needs to pass a message to the user, it does so by generating a
       MooseX::App::Message::Envelope object. The object usually contains one or more blocks
       (MooseX::App::Message::Block) and can be easily stringified.

       Usually a MooseX::App::Message::Envelope object is generated and returned by the
       new_with_command method in MooseX::App::Base if there is an error or if the user requests
       help.

       To avoid useless object type checks when working with this method,
       MooseX::App::Message::Envelope follows the Null-class pattern. So you can do this, no
       matter if new_with_command fails or not:

        MyApp->new_with_command->some_method->only_called_if_successful;

       If
