Instance Method Details

#option_parser ⇒ Object

Gets the root ‘option_parser`. Plugins do not append to this directly, but instead supply a list of options, arguments, descriptions, and default values. `SnapEbs` manages the namespacing of options, and each plugin receives its own `options` object.
