Returns the formatted usage by injecting given required arguments

    formatted_specific_usage += required_arguments_for(klass, specific_usage)
    # Add required options
    formatted_specific_usage += " #{required_options}"
    # Strip and go!

def run(instance, args = [])

implementation to create custom commands.
By default, a command invokes a method in the thor class. You can change this

def run(instance, args = [])
  arity = nil
  if private_method?(instance)
    instance.class.handle_no_command_error(name)
  elsif public_method?(instance)
    arity = instance.method(name).arity
    instance.__send__(name, *args)
  elsif local_method?(instance, :method_missing)
    instance.__send__(:method_missing, name.to_sym, *args)
  else
    instance.class.handle_no_command_error(name)
  end

rescue NoMethodError => e
