description         An HDF5 plugin supporting LZ4 compression/decompression.
long_description    ${description} Provides very high throughput compression \
                    and decompression. Use filter ID = 32004 to access. See \
                    also http://www.hdfgroup.org/services/filters.html for \
                    background.
