+
+#ifdef	DOCUMENTATION
+
+There are two macros you can define before including this file which can
+change the things defined by this file.
+
+DEBUG:	if defined, will cause enter/exit messages to be printed by the
+	ENTER/EXIT/EXITV macros.  If not defined, causes ENTER to do nothing,
+	and EXIT/EXITV to generate 'return' without any messages.
+
+	If defined, should be set to the name of the including module.
+
+MAIN:	Should be defined for a program containing a main() function which
+	is linked with other modules which include this file.
+
+	Value is not important, only existence/nonexistence matters.
