+// The following features are defined:
+//
+// CATCH_CONFIG_WINDOWS_SEH : is Windows SEH supported?
+// CATCH_CONFIG_POSIX_SIGNALS : are POSIX signals supported?
+// CATCH_CONFIG_DISABLE_EXCEPTIONS : Are exceptions enabled?
+// ****************
+// Note to maintainers: if new toggles are added please document them

+// Many features, at point of detection, define an _INTERNAL_ macro, so they
+// can be combined, en-mass, with the _NO_ forms later.
