     Consider taking a nap if you run Ant 1.6.x or 1.7.0 against a
     "big" setup.
 
-    The tests use the pathconvert task whose performance should be
-    dominated by directory scanner, they would use ressourcecount if
-    that had been available in Ant 1.6.5.
+    If Ant 1.6.x is detected or the property ant16 has been specified
+    on the command line then the tests will use the pathconvert task
+    instead of resourcecount.  So if you want to compare Ant 1.6.x
+    with later versions of you must specify ant16 on the command line
+    during your 1.[78].x tests.
 
     The tests will use the default settings of followsymlinks="true"
     and casesensitive="true" unless those values get overwritten by
