Instance Method Details

#exclude_options(*options) ⇒ Object

when #exclude_options is called on a command class, we take those options and generate a #recognised_options method overriding the parent’s #recognised_options to pull out the options we don’t want.

it probably seems odd that we’re calling #instance_eval here if this is to be modifying a class. Since we’re in the ClassMethods module while will be applied to the class, in the current scope, self is the class, so our current instance is the class definition.
