-fast storage and retrieval of R-objects like vectors, matrices and arrays to
-binary files in a language independent format.  The HDF5 format can therefore
-be used as an alternative to R's save/load mechanism.  Since h5 is able to
-access only subsets of stored data it can also handle data sets which do not
-fit into memory.")
