+ * WAX - it's a metaphor!
+ *
+ * The WAX framework allows an object to have generic/anyobj properties.
+ * These properties can be addressed through generic/anyobj identifiers.
+ *
+ * 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].as<type>();
+ *
+ * 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().
+ *
+ * Note: Do not put a class derived from wax::obj into an stl container.
+ * MSVC will compile the code, but the binaries will crash at runtime.
+ * Rather, use pointers or smart pointers to instances of the derived class.
