+ *
+ * Note the extra parenthesis around the DEBUG_printf macro...
+ *
+ * Newlines are not required on the end of messages, as both add one when

+ * If the first character is a digit, then it represents the "log level" of the

+ * current levels we use:
+ *
+ * 0 = public APIs, other than value accessor functions
+ * 1 = return values for public APIs
+ * 2 = public value accessor APIs, progress for public APIs
+ * 3 = return values for value accessor APIs
+ * 4 = private APIs, progress for value accessor APIs
+ * 5 = return values for private APIs
+ * 6 = progress for private APIs
+ * 7 = static functions
