description         HDF5 general purpose library and file format for storing\
                    scientific data

long_description    HDF5 is a data model, library, and file format for storing\
                    and managing data. It supports an unlimited variety of\
                    datatypes, and is designed for flexible and efficient I/O\
                    and for high volume and complex data. HDF5 is portable and\
                    is extensible, allowing applications to evolve in their use\
                    of HDF5. The HDF5 Technology suite includes tools and\
                    applications for managing, manipulating, viewing, and\
                    analyzing data in the HDF5 format.
