+\section evaluation_s3 Macro MUONCheckDI.C
+
+MUONCheckDI.C performs a consistency check on the methods of the
+AliMUONMCDataInterface and AliMUONDataInterface classes. There are several
+helper methods in these classes which make it easier to fetch data, which
+means there are at least two ways of fetching the data within the same class
+interface. The macro checks to see that the results given by these different
+methods are identical, as they should be.
+
+The macro also inherently exercises the AliMUONMCDataInterface and
+AliMUONDataInterface classes and should be run after any modifications to
+these classes to see if things still work. Putting it another way:
+MUONCheckDI.C is a testing facility for developers of these two classes.
