[Zope] - additional docs, of builtin modules and _ ?

Has any thought gone into extending the HelpSys stuff to also document the contents of _ and the standard builtin modules? I had something to just dump this out back under Principia at my last place of work - I could re-hack this, but it would be much prettier as a component of HelpSys.
