Subtasks

Mina provides the helper invoke to invoke other tasks from a task.

# config/deploy.rb
task :down do
  invoke :maintenance_on
  invoke :restart
end

task :maintenance_on
  queue 'touch maintenance.txt'
end

task :restart
  queue 'sudo service restart apache'
end

In this example above, if you type mina down, it simply invokes the other subtasks which queues up their commands. The commands will be ran after everything.
