[svn-r940] Purpose:

    New Feature

Solution:
    These files are the expected results of the HDF4 hdp dumper,
    which has been executed in the following order:

    hdp dumpvg file.hdf > file.dmp
    hdp dumpvd file.hdf >> file.dmp
    hdp dumpsds file.hdf >> file.dmp

Platform tested:
    Solaris2.5, HP10.20
