Passing in options to Composite Grammars

[davestevens]

I'm currently using the Ruby generation, I currently pass in objects to @init which I then use within the rules for computation.
I am attempting to utilize composite grammars but to do this I need to pass options through to the delegate. In the Ruby.stg there is the following:

newDelegate(gram) ::= <<
<gram.name>.new( <trunc(gram.delegators):{p|<p:delegateName()>, }>
  self, @input, :state => @state<@delegateOptions()>
)
>>

I have been searching and I can't see where @delegateOptions() comes from.
I want to be able to define it in the file which is performing the import to pass on extra options to the delegate. Is there any way to do this?
