+<tt>--mode=<normal|test|stress></tt> can be used to invoke "test" or "stress" mode, which are only useful if you're hacking on DMD. The default is normal mode.
 "test" and "stress" modes set their own <tt>--sample-below</tt> values, so you
 should never have to specify both <tt>--sample-below</tt> and <tt>--mode</tt>.
-To run the tests, specify <tt>--mode=test</tt> and start Firefox. It will print out some stuff and very quickly exit. Then run the following command from the top of your source directory.
-  memory/replace/dmd/check_test_output.py . test.dmd
-(If you invoked Firefox from a different directory to your source directory, you might need to specify the path to <tt>test.dmd</tt>.)
