-// Detect a number of compiler features - mostly C++11/14 conformance - by compiler
-// The following features are defined:
-//
-// CATCH_CONFIG_CPP11_NULLPTR : is nullptr supported?
-// CATCH_CONFIG_CPP11_NOEXCEPT : is noexcept supported?
-// CATCH_CONFIG_CPP11_GENERATED_METHODS : The delete and default keywords for compiler generated methods
-// CATCH_CONFIG_CPP11_IS_ENUM : std::is_enum is supported?
-// CATCH_CONFIG_CPP11_TUPLE : std::tuple is supported
-// CATCH_CONFIG_CPP11_LONG_LONG : is long long supported?
-// CATCH_CONFIG_CPP11_OVERRIDE : is override supported?
-// CATCH_CONFIG_CPP11_UNIQUE_PTR : is unique_ptr supported (otherwise use auto_ptr)
-
-// CATCH_CONFIG_CPP11_OR_GREATER : Is C++11 supported?
-
-// CATCH_CONFIG_VARIADIC_MACROS : are variadic macros supported?
-// CATCH_CONFIG_COUNTER : is the __COUNTER__ macro supported?
-// ****************
-// Note to maintainers: if new toggles are added please document them
-// in configuration.md, too
-// ****************
-
-// In general each macro has a _NO_<feature name> form
-// (e.g. CATCH_CONFIG_CPP11_NO_NULLPTR) which disables the feature.
-// Many features, at point of detection, define an _INTERNAL_ macro, so they
-// can be combined, en-mass, with the _NO_ forms later.
-
-// All the C++11 features can be disabled with CATCH_CONFIG_NO_CPP11
