+;------------------------------ Header File ---------------------------------
+;   This is basically a combo of MarctheMER's and Neviksti's header files
+; Perhaps reading their's will also help your understanding of the header,
+; but I believe this will be the simplest method of defining your header,
+; as Marc's doesn't provide a full explanation, and Neviksti's can be
+; a bit more difficult for beginners (using the WLA directives is easier).
