Subject: The meanings of Asterisk (and Webby)

Hi all!

I have a class that is used in a Webby page. The class needs to make
use of a function within three modules:

--------------------------------------------
module Webby
module Helpers #:nodoc:
module UrlHelper
--------------------------------------------

Since the function is an "instance"
function, I need to include the modules like so:

--------------------------------------------
class Categoriser
	include Webby::Helpers::UrlHelper
--------------------------------------------

Later in my class I have (bear with me):

--------------------------------------------
def render
..
  html << %[<li> #{link_to_page(:title => r.title)} </li>]
--------------------------------------------

link_to_page (within the three modules) looks like this:

--------------------------------------------
 def link_to_page( *args )
    self.link_to(*_find_page(args))
  end
--------------------------------------------

And gives me:
NoMethodError Exception: undefined method `find' for nil:NilClass

I can't find any reference to this usage of the asterisk, and
I don't know what the *_find_page does. Can anyone explain it to me?
