-// How to define a type safe enum list using the ENUM_CLASS macros?
-// ===============================================================
-// To get an enum list like this:
-//
-// enum class MyEnums {
-// Value1,
-// Value2,
-// ...
-// ValueN
-// };
-//
-// ... write this:
-//
-// ENUM_CLASS(MyEnums) {
-// Value1,
-// Value2,
-// ...
-// ValueN
-// } ENUM_CLASS_END(MyEnums);
-//
-// The ENUM_CLASS macros will use C++11's enum class if the compiler supports it.
-// Otherwise, it will use the EnumClass template below.
-
-#if COMPILER_SUPPORTS(CXX_STRONG_ENUMS)
-
-#define ENUM_CLASS(__enumName) \
- enum class __enumName

-#define ENUM_CLASS_END(__enumName)

-#else // !COMPILER_SUPPORTS(CXX_STRONG_ENUMS)
-
-// How to define a type safe enum list using the EnumClass template?
-// ================================================================
-// Definition should be a struct that encapsulates an enum list.
-// The enum list should be names Enums.
-//
-// Here's an example of how to define a type safe enum named MyEnum using
-// the EnumClass template:
-//
-// struct MyEnumDefinition {
-// enum Enums {
-// ValueDefault,
-// Value1,
-// ...
-// ValueN
-// };
-// };
-// typedef EnumClass<MyEnumDefinition, MyEnumDefinition::ValueDefault> MyEnum;
-//
-// With that, you can now use MyEnum enum values as follow:
-//
-// MyEnum value1; // value1 is assigned MyEnum::ValueDefault by default.
-// MyEnum value2 = MyEnum::Value1; // value2 is assigned MyEnum::Value1;
