-      Historically this option has been passed to the script.  This is
-      supposedly because at the beginnig the script was placed outside
-      of the ruby source tree.  Decades passed since the merge of
-      YARV, now I can safely assume this feature is obsolescent.  Just
-      ignore the passed value here.

-      This option used to override VM option that is defined in
