Hi,

I added some changes to CVS. This changes enables automated wrapping
of Key-Value Coding accessors. When you define a subclass of 
NSManagedObject, RubyCocoa defines wrappers to attributes and 
relationships from CoreData models.

my Employee.rb at chapter 3.
-------------
require 'osx/cocoa'
require 'osx/coredata'

class Employee < OSX::NSManagedObject
  
  kvc_depends_on [:lastName, :firstName], :fullNameAndID

  @@temp_id = 0
  
  def fullNameAndID
    sprintf('%s, %s (%d)', lastName.to_s, firstName.to_s, employeeID)
  end
  
  ns_overrides :awakeFromInsert
  def awakeFromInsert
    @@temp_id += 1
    self.employeeID = OSX::NSNumber.numberWithInt(@@temp_id)
  end
  
end
-------------

A new module function OSX::CoreData.define_wrapper() is core of the 
feature.
