description         Provides dynamically loadable (compression) filters for HDF5
long_description    ${description}. Filters for bitshuffle, bzip2, and lz4 are \
                    included. See also \

notes \
"To enable, use (with H5Pset_filter()):\n filter_id = 307   for bzip2\n\
filter_id = 32004 for lz4\n\
filter_id = 32008 for bitshuffle\n\n\
To enable use from Matlab, or other tools expecting the default HDF5 plugin\
path, create the required symbolic link:\n \
 mkdir -p /usr/local/hdf5/lib\n \
 ln -s ${prefix}/lib/hdf5 /usr/local/hdf5/lib/plugin"
