[svn-r942] PURPOSE: New Feature SOLUTION: h5toh4 is an H5 utility which converts HDF5 files into HDF4 files. It converts only those H5 objects which have have mappings into H4 objects. Some H5 objects that may be converted into H4 objects are: 1) H5 group objects may be converted into H4 Vgroup objects. 2) H5 dataset objects of integer or floating point datatype may be converted into H4 SDS objects. 3) H5 dataset objects of compound datatype and rank 1 may be converted into H4 Vdata objects. Field members of the compound datatype are constrained to be single dimensional. Platforms tested: Solaris2.5, HP10.20
