// Note there is no @ in front of test above.  This is so that the
//  harness will not mistake this file as a test file.  It should
//  only see the html file as a test file. (the harness runs all
//  valid test files, so it would run this test twice if this file
//  were valid as well as the html file.)
// Also, note the area= after Your Name in the author tag.  Here, you
//  should put which functional area the test falls in.  See the
//  AWT-core home page -> test areas and/or -> AWT team  for a list of
//  areas.
// There are several places where ManualYesNoTest appear.  It is
//  recommended that these be changed by a global search and replace,
//  such as  ESC-%  in xemacs.
