The Console package provides the infrastructure for building command line applications with the Joomla! Framework.

Add "joomla/console": "~3.0" to the require block in your composer.json and then run composer install.

{
	"require": {
		"joomla/console": "~3.0"
	}
}

Alternatively, you can simply run the following from the command line:

composer require joomla/console "~3.0"

If you want to include the test sources and docs, use

composer require --prefer-source joomla/console "~3.0"
