+  Assumes that the definition of ROM in apple.c has
+  been commented out.
+
+  This program is a successor to my 'interpreter.c'
+  utility, which unfortunately did not keep up with
+  the progress of my program.
+  This one works by letting you program the ROM with
+  whatever machine code you want.
