Commands
Commands are simply pre-defined styles for specific output:
$climate->error('Ruh roh.');
$climate->comment('Just so you know.');
$climate->whisper('Not so important, just a heads up.');
$climate->shout('This. This is important.');
$climate->info('Nothing fancy here. Just some info.');
Note that the error command simply applies styles and sends the default stream (using STDOUT). To send content to STDERR see the section on Output.
