+#### `UNITY_SUPPORT_VARIADIC_MACROS`
+
+This will force Unity to support variadic macros when using it's own built-in 
+RUN_TEST macro. This will rarely be necessary. Most often, Unity will automatically
+detect if the compiler supports variadic macros by checking to see if it's C99+
+compatible. In the event that the compiler supports variadic macros, but is primarily
+C89 (ANSI), defining this option will allow you to use them. This option is also not 
+necessary when using Ceedling or the test runner generator script.

 ## Getting Into The Guts
 
 There will be cases where the options above aren't quite going to get everything
