  Description: 

1. converter

See HDF4 to HDF5 mapping specification at
(http://hdf.ncsa.uiuc.edu/HDF5/papers/h4toh5) for the default mapping 
from HDF4 object to HDF5 object.
 
The whole converter includes 10 files, h4toh5util.h, h4toh5main.h, h4toh5util.c, h4toh5main.c, h4toh5sds.c, h4toh5image.c,h4toh5vdata.c,h4toh5vgroup.c,h4toh5pal.c and h4toh5anno.c.

2. this file 

Converting an hdf4 independent vdata object into an hdf5 dataset of compound dataset.
