# Input: -d dir generated_file foo1 foo2 . . .
#        Compares generated file with "_jni/foo1.h", and
#        generated file with "_jni/foo2.h", etc.
#
#        (NOTE:  unlike its closely related cousin, outofdate.pl,
#                the "-d dir" must always be specified; also, unlike
#                its closely related cousin, jniregen.pl, if the generated file
#                is older than ANY "_jni/foo?.h", then the generated file will
#                be regenerated in its entirety, rather than just the portions
#                associated with the list of files returned by this script)
#
# Returns: list of headers which are NEWER than corresponding class
#          files (non-existant header files are considered to be real old :-)
