-
-    For example, this command line:
-
-       mx unittest -G:Dump= -G:MethodFilter=BC_aload.* -G:+PrintCFG BC_aload
-
-    will run all JUnit test classes that contain 'BC_aload' in their

-
-    To get around command line length limitations on some OSes, the
-    JUnit class names to be executed are written to a file that a
-    custom JUnit wrapper reads and passes onto JUnit proper. The
-    MX_TESTFILE environment variable can be set to specify a
-    file which will not be deleted once the unittests are done
-    (unlike the temporary file otherwise used).
-
-    As with all other commands, using the global '-v' before 'unittest'
-    command will cause mx to show the complete command line
-    it uses to run the VM.
