 To run narcissus with jstests.py, change to the js/src/tests/ directory and run
 the following command (which excludes tests that are particularly slow):
 
-  python jstests.py -d -j 4 $OBJDIR/njs -m narcissus.list -x slow-narcissus.txt
+  python jstests.py -d -j 4 $OBJDIR/njs -x slow-narcissus.txt
 
 
-The js/src/tests/narcissus directory can be used for any tweaks that might be needed
-to make Narcissus work properly.  Currently, Narcissus is failing a number of
-tests.  narcissus-failures.txt can be used to ignore those tests.  Note that
-narcissus-failures.txt also includes all of the tests from slow-narcissus.txt.
