ActsAsWrappedClass
    by David Stevenson 
    http://flouri.sh

== DESCRIPTION:
  
ActsAsWrappedClass is designed to automatically generate a wrapper for an object that you don't want to be allowed to access certain methods in.  This is useful in cases where you want to sandbox what users' code can and can't do, by providing them access to the wrapper classes rather than the original classes.

== FEATURES/PROBLEMS:
  
*  Wrappers do not dispatch const_missing yet, so constants are not accessible yet.

== SYNOPSIS:

	class Something
	  acts_as_wrapped_class :methods => [:safe_method]
	  # SomethingWrapper is now defined
  
	  def safe_method  # allowed to access this method through SomethingWrapper
	    Something.new
	  end

	  def unsafe_method  # not allowed to access this method through SomethingWrapper
	  end
	end

	s = Something.new
	wrapper = s.to_wrapper
	wrapper.safe_method    # returns a new SomethingWrapper
	wrapper.unsafe_method  # raises an exception

== REQUIREMENTS:

* none

== INSTALL:

* sudo gem install acts_as_wrapped_class
