+description = """SIONlib is a scalable I/O library for the parallel access to
+task-local files. The library not only supports writing and reading
+binary data to or from from several thousands of processors into a
+single or a small number of physical files but also provides for
+global open and close functions to access SIONlib file in
+parallel. SIONlib provides different interfaces: parallel access using
+MPI, OpenMP, or their combination and sequential access for
+post-processing utilities.
