An HDF5 +attribute is a user-defined HDF5 structure that provides extra information +about an HDF5 object. +<P> +Working with groups and group members (datasets for example) is similar in many +ways to working with directories and files in UNIX.

After the +example, an HDF5 tool is used to examine the file contents.
