 39# Input: -d dir -j javahcmd foo1 foo2 . . .
 40#        Compares generated "_jni/foo1.h" file with "foo1.class", and
 41#        generated "_jni/foo2.h" file with "foo2.class", etc.
 42#        (NOTE:  unlike its closely related cousin, outofdate.pl,

 46# Returns: list of headers which are OLDER than corresponding class
 47#          files (non-existent class files are considered to be real old :-)
