Revised Commands -> use symfony/console -> php ma (MyAAC)

Usage:
php ma list
php ma cache:clear
php ma plugin:install guild-wars.zip

More sophisticated:
echo "Hello, this is hello world message" | php ma mail:send test@test.com --subject "This is subject"

Also: custom commands can be added via Plugins: just need to return new class instance that extends \MyAAC\Commands\Command in plugins/*/commands folder
