+ * \section intro_sec Introduction
+ *
+ * The C++ API provides C++ wrappers for the HDF5 C library.
+ * It is assumed that the user has knowledge of the HDF5 file format 
+ * and its components.  If you are not familiar with HDF5 file format,
+ * and would like to find out more, please refer to the HDF5 documentation
+ * at http://hdf.ncsa.uiuc.edu/HDF5/doc/H5.intro.html
+ *
+ * Because the HDF5 library maps very well to 
+ * the object oriented design approach, classes in the C++ API can 
+ * closely represent the interfaces of the HDF5 APIs, as followed:
+ * 
+ * \verbatim
+ 	HDF5 C APIs				C++ Classes
+ 	-----------				-----------
+ 	Attribute Interface (H5A)		Attribute
+ 	Datasets Interface (H5D)		DataSet
+ 	Error Interface (H5E)			Exception
+ 	File Interface (H5F)			H5File
+ 	Group Interface (H5G)			Group
+ 	Identifier Interface (H5I)		IdComponent
+ 	Property List Interface (H5P)		PropList
+ 	Reference Interface (H5R)		Reference
+ 	Dataspace Interface (H5S)		DataSpace
+ 	Datatype Interface (H5T)		DataType
+  \endverbatim
+ * \section install_sec Installation
+ *
+ * Please refer to the file release_docs/INSTALL
+ * under the top directory for information about installing, building,
+ * and testing the C++ API.
