Most information about this package from the readme.txt. 
This file only highlights what's new in this release.
1. Upgrade the source code to HDF5 1.8 APIs. The current release will not support
HDF5 1.6 anymore. 
2. Re-organize the directories. unittest directory is removed. Add two new directories:
validprog and examples.
One can check the tool with sample files under the examples directory. Follow the simple 
readme under the examples directory to check. 
The source code and makefile template for the validation program has been moved to the validprog
directory.
3. Update makefile.augment and makefile.check for manually building the tool.
4. Completely rewrite readme, validation and usage docs. 
5. Provide a 64-bit static binary at http://hdfeos.org/software/aug_hdfeos5.php
