 program options).

  * WAX - it's a metaphor!
  *
- * The WAX framework allows object to have generic/anyobj properties.
+ * The WAX framework allows an object to have generic/anyobj properties.
  * These properties can be addressed through generic/anyobj identifiers.
- * A property of a WAX object may even be another WAX object.
  *
- * When a property is a WAX object, the returned value must be an obj pointer.
- * A WAX object provides two objs of pointers: obj::ptr and obj::sptr.
- * The choice of pointer vs smart pointer depends on the owner of the memory.
+ * The WAX object itself is an anytype container much like boost::any.
+ * To retrieve the value of the appropriate type, use my_obj.as<type>().
  *
  * Proprties may be referenced though the [] overloaded operator.
  * The [] operator returns a special proxy that allows for assigment.
  * Also, the [] operators may be chained as in the folowing examples:
- *   my_obj[prop1][prop2][prop3] = value
- *   value = my_obj[prop1][prop2][prop3]
+ *   my_obj[prop1][prop2][prop3] = value;
+ *   value = my_obj[prop1][prop2][prop3].as<type>();
  *
- * Any value returned from an access operation is of wax::obj.
- * To use this value, it must be cast with wax::cast<new_obj>(value).
+ * Property nesting occurs when a WAX object gets another object's link.
+ * This special link is obtained through a call to my_obj.get_link().
