Method: Drydock::Command#show_commands

Defined in:
lib/drydock.rb

#show_commands ⇒ Object

Print the list of available commands to STDOUT. This is used as the “default” command unless another default commands is supplied. You can also write your own Drydock::Command#show_commands to override this default behaviour.
