#initialize(slop, short, long, description, config = {}, &block) ⇒ Option
Incapsulate internal option information, mainly used to store option specific configuration data, most of the meat of this class is found in the #value method.
slop - The instance of Slop tied to this Option. short - The String or Symbol short flag. long - The String or Symbol long flag. description - The String description text. config - A Hash of configuration options. block - An optional block used as a callback.

#value=(new_value) ⇒ Object
Set the new argument value for this option.
We use this setter method to handle concatenating lists. That is, when an array type is specified and used more than once, values from both options will be grouped together and flattened into a single array.
